How to restore stock firmware on Samsung Galaxy S2? (Video)

Hi Jayce,

Need to ask, where do you get the micro usb jig? Can provide me the seller or a place where can i get it or can I make it my self? Another thing is what’s the function of the usb jig? Is it necessary to reset the download counter for warranty purposes? Ouh and if I root the phone what happens to the apps that I already purchased or installed in my phone?

hi jayce,
in the above video which custom rom were u using?

Hey

Thanks for some great guides regarding the samsung galaxy S2.

However, I have a question.

I have rooted my phone using odin, and I am thinking about install lite’ning rom v6.1. But how do I restore to the stock rom? As far as I can tell this only show how to restore the firmware, so the phone is not rooted anymore. I have titanium backup pro on my phone and I have made a backup of the phone, so can I use those files to restore back to stock rom with root?

Hobe you understand and are willing to answer 🙂

Best regards

Nick

Wow man, thanks!
Currently on rooted custom rom, so if anything happen in later flashes I’ll have this guide 🙂
Just ordered a USB jig from eBay.

All the best from Norway!

If I want to restore to the official firmware after root, will my contact and message still remain? Do I need any backup before restore? If yes, what software can I use to backup and how to restore back the contact and message.

Thanks.

hi jayce. i had lite’ning v.6 and thought of going to v.5. it was ok after i had the v.5 but then i thought i had to do a “recovery” so i did. when my phone rebooted, it usually starts with the S logo, right? the thing is my phone is kind of in a loop–rebooting over and over, & showing the S logo over and over again. i’ve tried to root my phone again to v.5 a couple of times, and then back to v.6 but it still shows the same thing.
what can i do?

hi Jayce, do I need usb jig if i will be resetting to factory setting?

Hey if I want to send it for warranty do I need the usb jig? I mean will they check?

how to do this without usb jig????????????

So what actually does the usb jig part do? is it necesary to revert to stock firmware, does it void warranty if you dont use it (cause i dont have it btw :p)?
i recently upgraded to the DXKH1 southeastern asia firmware, to get to the point the languages on that version are too limited and i’d like the previous ones back, like most of the european ones could you help me? i also asked this similiar question on the DXKH1 thread so forgive me for being frequent, but i am in a time of great need of assistance!
Greetings michael

Will this allow me to remove the Network start up video, widget etc?

Hi,
I got a galaxy s2, because the in-call volume too low, I followed some blog and entered into the service mode menu and tried to set some hidden setting to increase the volume. I think I stuffed up the setting, I tried to preform a factory reset, it doesn’t seen to reset everything. Will I follow your restore/flash guide above, it will fix my problem?.. Please help

Jayce,

Just to ask u about differences for the below

What is Baseband Version?
What is Kernel Version?
What is Build Number?

Currently my phone i using XXKH3 on the baseband, 2.6.35.7-I9100XXKG5 on the kernel and GINGERBREAD.XXKG5 on the Build number.

hello….i have a question….i have a galaxy s2 i9100 and there’s the thing….. i have for like 1 week and i installed the kies ….then its ask me to update the firmware to the new one….(this was like 3 days after i have the phone) then i did the update…. the problem is now after that my 4g network doens’t work only the slow one…. i tried to wipe all phone on the ”bios” and it doens’t come to the old firmware…. i’m in U.S. using t-mobile ….. can be the update is from europe when i did on kies!? u have to do this on this video to fix it!? please some help…. i’m going crazy without 4g network ( cuz the phone i had before was galaxy s t959v 4G so i miss fast internet lol )

Where to get usb jig?

may i know why after i do as you said my baseband and build no. is not the same?

my BASEBAND VERSION IS I9100XXKH3
KERNEL VERSION 2.6.35.7-I9100XWKF1-CL265340 ROOT@DELL06 #2
BUILD NUMBER GINGERBREAD XWKF1

I did this according to your guide but in download mode there is a odin logo?

@kevin: Yes, the official firmware DXKI2 is still Android 2.3.3. Samsung Kies will let you know if there is new firmware upgrade.

Will my s2 still be rooted after following this guide? Thanks.

Hai Jay,

My sgs2 won’t come into the clockworkmode recovery. only it shows volume up for update and volume down to cancel.
thank you

When I start phone in download mode there is no option to wipe data/factory reset?

Hi I need help because the problem is i got an samsung galaxy overseas from the UK and got it shipped here into the USA and it an galaxy s2 factory unlocked and unbranded but i dont know what firmware kernel is the official one for it Below is what shows up in about phone but i dont know if i flashed the right kernel or rom for it
Model number: GT-I9100
Android Version: 2.3.3
Baseband Version: I9100XXKE4
Kernel Version: 2.6.35.7-I9100ZSKE7-CL225635 root@avad-server #2
Build Number: GINGERBREAD.XWKE7

THIS IS WHAT I GET WHEN I ENTER *#1234#

PDA:I9100XWKE7
PHONE: I9100XXKE4
CSC: I9100XEUKD1
Build Info: Wed May 18 16:08:22 KST 2011

IF YOU COULD EMAIL ME AT alonzo.madonna@gmail.com or alonzo.madonna@yahoo.com
letting me know what is the right official stock kernel and rom for the phone
again i dont believe xwke7 or xxke4 where the ones first on here but i could be wrong
THANKS FOR ALL THE HELP 🙂

ALSO I TRIED TO UPDATE THE PHONE AND IT FAILS EVERY TIME DO YOU KNOW HOW TO FIX THIS I JUST WANT STOCK BACK AND NO ROOT CWM WHAT SO EVER JUST PLAIN OLD SAMSUNG STOCK

ALSO CAN I FLASH IT WITH A US STOCK ROM

MINE WAS IMPORTED FROM UK SO THE FIRMWARE IS MOST LIKELY UK

I WILL TRY KF1 seems common among unlocked version if not

what is the best all around rom
which is best
cm7
miui
villianRom
ligthingRom
Batisa70
madmack
or any others you know of which is the best all around

also how can you change boot animation im not that advanced with linux script coding
any easier way to do it

MIUI for Looks
Batisa70 for Performance (1.6ghz) its also unvolted
Madmack for Tweaks But Closer To Stock
Lighting Rom for Battery but with little tweaks
VillianRom for Insane Battery Life
LeoMar75 for Full Tweaks
CM7 for Classic android which battery as well as little performace tweaks

The top two are Batisa70 and Lighting Rom
CM7 needs stable version
most roms use it framework like miui

I like your video, I understand, but I not have USB Micro Jig. Is it so important? How do I build one?

Thank you very much for explanation .

Hi Jayce,
I like to say thank you for your support.
My problem is: I have SG2 from China now I’m living in Europe. The original firmware was ZCKG4 after update fail with Europe firmware now I use ZNKG5 also Chinese firmware. Any chance to bring my android to international firmware in order to have access to android market and other app???

Hi Jayce,
Malaysia/Singapore firmware I9100DXKH2_I9100DXKH1_I9100OLCKH1 is not working unfortunately. Any advice?

Hi Jaycee,

Badly need your help because I’ve happened to bricked my Galaxy S2 phone after using the cyanogenmod 7.1 custom rom for quite a while and trying to install back the GS2 stock ROM. Is there any way I can do to resolve this? Before this event happen though, I’ve been experiencing some problems with the SD card not being mounted and says that it should be reformatted. Does this not cover the Samsung warranty? Does it already void my warranty?

Thanks in advance!

I’ll go and check later and give you the exact result when using Odin as I’m not home at the moment. 😉

For all wich have chinese android and wish to change into EUROPE rom read the: http://forum.xda-developers.com/showthread.php?t=1192575&page=3

Hi Jayce,

I rooted my SGS2 using Odin following the normal steps. However, I tried installing customized theme.
“using recovery mode via installation through SD card “.
I am having this two problem:
TW launcher cant launch at all.

I try to boot back to original firmware with the aid of your video. but problem still persist.
Any idea or solution?
Thanks in advance

Do u suggest I try rooting it again and try ur steps. The stock firmware which I downloaded is unbranded. Is there any issue with that?

Hey, man! I’m having a problem here when trying to go back to stock rom. In fact, there are two problems.
First one is: I have no idea what stock rom I should use. There are lots of them in here (http://forum.xda-developers.com/showthread.php?t=1075278) and I wonder how could I know witch one to install.

Anyway, I went ahead and tryed the XXKI3 version. Followed all your instructions (just without the jig), but when the phone rebooted, Cyanogenmod was still there! =T

Any ideas?

Hi Jayce,

hello,

umm ever since i’ve flashed lite’ning rom v6.1 xxkh3 into my sgs2 the camera’s sound was not working and also the quality of the image is not like the usual it has very low quality 🙁 .. do you think that if i could restore the stock firmware could get the camera’s sound and quality back?

🙁

Good day Jayce, I tried to reset the binary counter using a home made usb jig but it doesn’t work. I managed to have 308k ohm through an electronic board and also tried simple series resistors through pins 4 & 5 with no success. What are the common mistakes in your opinion when making usb jig?

Thank you Jayce for your quick response, my firmware is XWKE7 (Build date: 18/05/2011) downloaded last week. Is it possible firmwares were updated with usb jig banned?

hi jayce! i have a question again sir.. is it ok if i factory reset(in the settings) my phone..my firmware is XXKI4 CF-Root now. is it ok? and what does it do? tnx!

hi mate,,

pleaese help me if you can,

i had the miui rom to my phone.. and after trying to put the original kernel of android i couldnt
upgrade it from kies…it writes that i cannot upgrade the firmware via kies,,
is this because i didnt use any usb jig ? and just install the xwki4 without usb jig/?
thankyou

Once i reload the stock firmware, is the device able to download updates over the air? Or is it locked to the firmware that u put on it? is there any way to totally reboot your device in every way, like manufactural rest the device just as it comes in the box?

I don’t get futher then step 16..

Hi, i have a white S2 and im from singapore, i root the custom lite ning rom and now i wan to flash back. I cannot remember my stock 2.3.3 version kernel so i dun dare to do the reflash to stock.

now im on kh3. Which stock firmware must i download?

My phone info:
Android version: 2.3.3
Baseband: I9100DXKI1
Kernel: …DXKI2..
Build: GINGERBREAD.DXKI2

What I found in the http://forum.xda-developers.com/showthread.php?t=1075278, under DXKI2, there’s 2 download links

1. OLC MultiCSC
2. DXKI2 Stock Kernel

Just want to double confirm, if I already rooted using CF-Root (without flashing any ROMs), and want to revert back to the stock kernel, I only need to download “DXKI2 Stock Kernel” and follow the instructions above? Thanks in advance 🙂

So, if I don’t use USB Jig to restore stock firmware, it is void warranty or there are warranty?

LoL, i need to take out battery 1st and then replug back. After that just can run the bootloader. Anyway, thanks you again.

Hey, can i use this method to flash back the stock firmware with the unrooted phone?

Can I use kies for official update after this?

I downloaded the stock FW as described
my phone now shows:
android 2.3.5
baseband: I9100NEKI2
KERNEL: 2.6.35.7-I9100XXKWB-CL616395ROOT@DELL149#2
BUILD: GINGER BREAD XWKI8

KIES Now doesnt show any firmware version and the space is blank. what is all this and how i can fix it to get future updates through kies

thanks…..

Excues me, noob question here…
If i rooted my sgs2 with cf root
and i follow the steps above , my sgs2 will be totally back to stock rom and unrooted?

Green light to service center?

do you know how to unlock carier?

hey thise firmware is bugs i donload many firmware from sam but still bug some time 3g prob some time lockscreen waiking up slowely i give to servise center they will help i hope 🙂

hi jayse android 2.3.5 have a other bootloader and you can not use the jig for it for reset wat must i do flash to android 2.3.3 ?

Before i rooted my phone, i created backup via kies so i could restore last settings made before root should anything go wrong. After root (CF root) and flash custom rom, none of my user apps were seen (I guess this is the case). Now I want to restore to previous settings. I found this tutorial but can’t seem to understand where to get stock firmware?

baseband ver: I9100XXKI1
kernel ver: 2.6.35.7-I9100XWKI4-CL575468root@DELL143#2
build#: GINGERBREAD.XWKI4

Above is as per phone info before root.

Song of the video, who sings ? It is very pleasant.

Hey jayce, thanks for the video.

My current kernel version is jpkj2 and my question is that I want to flash another stock firmware on it lets say xwke1. could that process brick my phone or it doesn’t matter ?

do i have to have the usb jig? or is it someother way to do it without the jig?

Hi Jaycee
. Thanks very much for the painstakin efforts u took to bring out such fab. video
I’ve rooted my SGS 2 with an insecure kernel first, then rooted it with s2root application and then flashed the secure kernel to remove the yellow triangle. Since i didn’t had the clockworkmod, i then followed ur method of rooting with cfroot kernel. After that I installed MIUI rom but i want to revert back to the stock rom. Will i have to follow any special procedure to do so, or the one you mentioned in the video is enough?
Have I done the wrong thing by following the 2 different methods of rooting? I did the root by cfroot kernel the next day after doing it by the first method.
My firmware version was XWKE8

I’m from Holland and want to thank you guys. It works on my galaxy S2. This video was very useful

Hey….if im from Malaysia…should i choose the Malaysia firmware or can i choose the UK?

Hi, so if i’ve recently flashed to a euro stock firmware XKK2? (2.3.6) and i would like to send it to my local service centre i have to flash back to stock firmware?

where to dwload stock firmware xwkf1?

odin not detect my phone why??

where to download usb drivers

how to fix baseband unknown??

Hey Jayce…..my SGS2 is using MIUI Rom but now i want to go back to original…..what do i need to download? firmware and stock kernel? or just firmware?

i found the XXKH3 firmware….but it won’t be able to update to new firmware using KIES…i cant find XXKH3 firmware that can be update to new firmware using KIES…

@Samarth Kumar: Install it with CWM. https://www.jayceooi.com/2011/08/10/download-bios-boot-animation-for-samsung-galaxy-s2/

Custom kernel has more tweaks. Depend on each person needs.

You can delete the Android zip after installed it.

Hey Jayce….can you tell me which stock firmware is the best and the newest?

do u really need a USB JIG to restore the firm ware on the phone to stock

Hello Jayce!
Great website!

I just want make sure one thing… Maybe it’s a stupid question: My phone is rooted I bought already like that. Will I lose the root access?

Hi Jayce.

My phone details are:

Android 2.3.5
PDA: I9100BGKJ3
PHONE: I9100XXKI4
CSC: I9100XECKJ2
Kernel: 2.6.35.7-I9100BGKJ3-CL691334 root@DELL128#2

After rooting my S2 with CF-Root-SGS2_XW_XEN_KJ3-v5.0-CWM5, wifi is not working properly, it can’t get a dynamic ip address with dhcp. I’m confused for that reason and I’m thinking to restore stock firmware because I tried to reset defaults and it didn’t solve the problem. Maybe rooting felt bad to my S2 or CF-Root file used was not the correct one?

So, I would like to restore stock firmware.
I downloaded the following from http://forum.xda-developers.com/showthread.php?t=1113928 searching my spanish firmware of Movistar:

BGKJ3: http://www.multiupload.com/DKXEKP8HU6
Firmware info: PDA:BGKJ3| PHONE:XXKI4| CSC:XECKJ2

BGKJ3 Stock Kernel: http://www.multiupload.com/H2F054ICEK
Password: intratech@XDA

Those give me two files:

GT-I9100_XEC_I9100BGKJ3_I9100XECKJ2_I9100XXKI4.TAR.md5
Kernel_I9100BGKJ3.TAR.md5

Could you tell me if I should use the first file
(GT-I9100_XEC_I9100BGKJ3_I9100XECKJ2_I9100XXKI4.TAR.md5) in PDA and without enabling “Re-partition” then I would restore stock firmware?

After that, would I see the yellow exclamation?

Thanks in advance!

hey,i did everything exactly as you did but after i close odin and my phone reboot it shows the s2 logo and then againn reboot!!!!!!!what should i do?????

i wipe data/factory reset again again and again and the same thing

plzzzz can we talk together on skype to show you my problem on video call cause i don t know what to do plzzzz

no i dont know.can you tell me how?

Hello,
I downloaded my stock ROM XWKF3 for i9100 through xda.There I saw link for stock kernel KF3 also.When I downloaded stock kernel from xda,I see that it’s an EXE program.
Now I want to know-
1.when and why is this stock kernel required(the restore-firmware guide says only .tar from downloaded firmware is required)
2.whenever it’s needed,how can exe be used on my android?
3.At the time of root,I downloaded original and “insecure” kernels for my series XWKF3 from xda.So I wan under impression that this “original” i9100 kernel is SAME as stock kernel.But now I see Stock Kernel on the link you mentioned is roughly 5MB while the original kernel that I downloaded while rooting is 8MB.SO are these two different?If yes,which one is REAL stock (original)kernel?
Thanks .

Hi Jayce,

When you flash the stock ROM again after wiping factory settings in ClockworkMod Recovery, does this remove ClockworkMod Recovery? I looked around and it seems to be awkward to remove it completely. If I wanted to go completely stock, will this method replace the ClockworkMod Recovery with the official Android system recovery ?

Thanks.

can i know where to get the usb jig? can i reset the binary counter without usb jig ? thank you

Can I dual boot into 2 roms such as miui and cm7 on my galaxy s2 i9100? plz. tell me about any elaborative procedure to do so and whether it’s safe or not. Any idea when will be the CM9 available for Galaxy S2?

Hello, your website rocks dude!!! I was wondering if you can help me with a video cuz I change some stuff from my sg2 but it was the issue of boot loop using this rom http://www.youtube.com/watch?v=QYmm4aqQ2fk, I reinstall the rom without the rooting process and no more booting, but it was a issue with some apps, now I used the rom that you posted the gingerbread 2.3.6 and everything is working fine, but I would like to clean all the configuration in order to make sure that mobile will be working properly, thank you

Thanks a lot! this really helped me revert back to stock. I had problems with a custom rom.

Hai, jay… i wanted to ask you for opinion…

previously my s2 was flashed bastisa 70 2.8 rom and i faced FC and so i reflash it again with recovery

and after i finish flashing, i straight go for CWM restore because i dont want bastisa anymore…

But now my restored stock (KL3) firmware having 20* android os (quite battery drain)

and i forgoten about the original firmware details

Currently,
Android version – 2.3.6
Basedband version – I9100XXKI3 (i can’t really recall it, but i think not KI3)
Kernel version – 2.6.35.7-I9100DXKL3-CL814816root@DELL137#2

Should i restore my phone to stock firmware again? and re cf root to get restore my logs and sms with titanium backup? Or there are other way?

Okay, tq jay^^
I take on my own risk

Hello buddy,

Thank you so much for this help mate. I wanted to revert the official ROM so desperately after upgrading to ICS 4. It was horrible with uncountable bugs and crashes. Shacks! Official is always better 😀

hi jayce,
whenever i install stock rom on my galaxy s2 indian version it goes into boot loop…
i hav tried 3 stock roms from xda forum and nothin has worked..it keeps going to boot loop…
i currently hav sensation rom 3…please help me install stock rom…

Hi jayse.
is this an indian firmware?
What about the mobile network?

I tried to go back from 2.3.6 to my customer firmware 2.3.3 but it keeps going into boot cycle.
the 2.3.3 is a single file that i upload to PDA using ODIN : I9100JPKH1_I9100XXKG5_I9100OJPKH1_HOME.tar

and the one i upgraded to (2.3.6) : alot of files that end with .tar.md5

now i havce the 2.3.6 running (sadly no arabic support).
how can i go back to the original 2.3.3 without going into the Boot cycle?

Hmmm . . .
Ok , i did again to make sure wipe is good.

still the same thing 🙂

i guess i’ll wait for a stable ICS release to come out, since i tried the 4.0.1 and 4.0.3 and they had some issues still.

thanks mate

Hey there,

I’m using the Samsung Galaxy S2 SGH-T989, Would this work for it too?

Hello,
i am in a bit of confusing situation,i purchased sgs2 from India on October with manufacturing date sept-2011 (manufactured in china exported to India)and earlier this week i updated my phone from 2.3.3 to 2.3.4 gingerbread XXKG3 after update the phone is draining up the battery very early as compared to the previous official stock firmware which was 2.3.3. i wanted to restore my stock official firmware but i don’t know my official firmware baseband or build or kernel version. i want exactly the same version of my official firmware as it worked perfectly with my phone. HELP

then which firmware should i go for? that saves my battery drainage and your download link is not working..

Is there any way to find my official firmware by product serial number or something like that..?
after updating to 2.3.4 through odin can i claim for warranty or restore back to official firmware from Samsung service centre in India.

and 1 more thing my phone display blips up after every 15 to 20 minutes and loops on for 3 to 5 times without touching the device is this normal or it can be fixed through settings menu.

Hi,
I have a problem and I am desperate to get help.
I have tried to root my phone and used Odin to put a tar file (6mb large) on my Galaxy S2. Now the phone gets stuck at the yellow sign part. I did a factory wipe and now I dont know what to do.How do I get my old firmware back? I dont know what is my firmware but I got my phone from Hong Kong. My girlfriend got the same phone from the same seller and hers says I9100xxkg1 and zskg2. What are the chances that this is the one I need ?
Where do I get it from

Dear While upgrading my galaxy s 2 it failed and now my mobile screen shows mobile an error symbol and PC. I restart it by taking out the battery but no difference. plz help

Interrupted firmware update – phone frozen with warning sign
Was trying to update firmware for my Galaxy S 2 and this was interrupted. Phone now shows a pic of a phone, 2 dots, a warning triangle, 2 more dots and a PC – and this will NOT go away, no matter what I do – viz try & switch off, take battery out, hold down every key, etc. etc.

Please help…!??

Hi, I followed your steps up to no. 20, which I understand is not necessary to go through.

I still can’t get Kies to upgrade my phone to the latest firmware, as my phone doesn’t allow it (I don’t get the pop up to press Yes on). I suspect it may still be rooted, as my kernel is named 2.6.35.7-I9100XWKE1-CL181974 root@DELL103 #2. Is this the case?

(Needless to say, I’m a noob who just managed to root my phone following your recipes. 😉

Hi Jayce,

I really liked your video and it was easy to follow…

However I need some help to find the firmware you are using as that is what was one my phone before I had it rooted now I need to go back…

I followed your link to XDA-Developers site, found the firmware I need however it is hosted on Multiupload.com which I believe is no longer available and taken down…

Can you help me find or provide me a link to the XWKF1 firmware??

Much Appreciated…

no worries…

Oh what about this site you had mentioned earlier to Ella??

I saw the PDA file for Australia (where I am located), assuming i can use this?

hi there,
I have a problem with my stock music player it doesn’t read my songs, but when i use another music player(PowerAMP) it reads all my songs. any solution

Thanks.

i also have another problem i had rooted my phone before, then i unrooted back flashed it back to normal with 1binary count…..now when i install the CSC manually *#272*IMEI# I cant find anything its just black.

The kernel version changes upon upgrading? cause i cannot find a firmware 2.3.6 for my PDA XXLPQ. Its already upgraded to 4.0.3. and onlhy that firmware i can find.

what is the official stock firmware for malaysia currently? i wanna send my fon to the service centre.

@azizi: Kernel is like the heart of Android operation system.

Hi Jayce… After flashing stock rom should i flash stock kernel related separately or it installed automatically while rom was flashing… Thanks

Hi, when I bought my phone it had this info:

1. Android version: 2.3.3
2. Baseband: I9100BUKG1
3. Kernel: 2.6.35.7-I9100BUKG2-CL342
4. Build number: Gingerbread.BUKG2

What stock firmware should I use from xda-forum thread?
Is XXKG2 good enough ? Also this means I will loose ROOT and CWM ? Now I have Cyanogen 7.1, and I wiped cache,factory reset in CWM. What else should I do ?

Jayce please tell me, is there any problem if I install a different region kernel on my SGS2 ?

Also what’s the difference between a Carrier firmware and an unbranded one? Which one do you recommend ? A Carrier firmware is blocked on using a SIM card of that carrier ?

Do I have to do factory reset

Hi Jaycee,

I just want to ask if it is ok to “unroot” your SGS2 using the stock ICS firmware? Do you think you can still claim your warranty from Samsung service centers?

Thanks!

Hi jayce!

My friend was running on ICS and wanted to revert back to gingerbread so I helped him flash

the stock firmware. But I messed up because I forgot to do a factory reset. I was stuck on the

android image wherein you have to choose what language to use and gives me an error

message so I can’t go anyfurther. After reboot I was unable to turn on the device again. I tried

using a jig but still won’t go to download mode. I also tried to replace the battery but still

nothing positive happened. I hope I did not destroyed the device. What can you suggest I

should do?

Do we need to root first to flash stock firmware or we could easily downgrade from stock ics to stock gingerbread without rooting?

Hey Jayce,
intratech hasn’t uploaded all the stock firmwares at his new site (http://androidfirmwares.net/PhoneFirmware) so i downloaded the XWKL1 firmware from http://www.sammobile.com/firmware/?page=3&t=1&o=1&m=GT-I9100&r=2#regiona
you think this site is good? should i go ahead to restore my phone to stock firmware using it?

Ok,so i want to do this because i think it will get rid of my battery drain problem..now i have one question…Do i need to download just firmware? Or kernel too? Thanks in advance 🙂 BTW,i will give you my about phone information:

Android version: 4.0.3
Baseband version: I9100XXLPS
Kernel version: 3.0.15-I9100XWLP7-CL340913
dpi@DELL134 #3
Build number: IML74K.XWLP7

Thanks mate so much,did it and it works good! 😀 THANKS <3

Hi Jayce! I went to the xda site for the stock roms. Mine is XWKF3. But I’m not really sure about the country (CPW,XEU,INU,etc) because i have no idea where my friend bought it from. I live in India. Which one should i choose? Would choosing a wrong one brick my phone?

When i get my phone connected in download mode my computer says the device is not recognised. then when i go into odin it cant find it. I got kies and the drivers but nothing. i really need help. (Before all this happened i tried rooting but failed as i used the wrong firmware)

HELLO JAYCE, my current sansung galaxy s2 firmware is 4.0.3 XWLPD updated using kies and now its rooted………..the Q which i want to ask from you is that ill need a stock firmware XWLPD 4.0.3 to restore it or any other firmware and after restoring it will downgrade to GB or remain same ie ICS

my current firmware is 4.0.3 XWLPD pda=lpd, phone=lpb ,csc=lpb…………now im going to restore my firmware back to ics so for RESTORING i need XWLPD 4.0.3 or i can use any other like XXLPQ etc there are many other firmware versions for 4.0.3………..which one i have to use

if i use any other like XXLPQ will it be installed on my device or i have only one choice i.e XWLPD

@hamza: Not familiar with other region CSC too. Mine is XME for Malaysia.

Not working! Can,t seem to get any further than wipe data/factory reset. After pressing this to activate the only next option i get is reboot. Which then goes back to the updated firmware.Please Help

Hello Jayce.

Recently I have upgraded my Samsung Galaxy S2 GT-I9100G (bought in Malaysia) from android version 2.3.6 to 4.0.3 through Kies on my computer. However I find that I liked the 2.3.6 version more than 4.0.3. So I’m deciding to downgrade it myself using Odin3v1.87.
Here are some of my questions.

1. I have downloaded the 2.3.6 version firmware (I9100GDZKL3_I9100GOLCKL3_XME) and the flashprograms (GT-I9100G Flasher + Pit) from sammobile.com. Is that an official firmware as it came with the box when I bought it?

2. So far I only had downloaded the 2.3.6 version firmware (I9100GDZKL3_I9100GOLCKL3_XME) and the flashprograms (GT-I9100G Flasher + Pit).

After unzipping (I9100GDZKL3_I9100GOLCKL3_XME), I get 2 files. I9100GDZKL3_I9100GDZKL3_I9100GOLCKL3_HOME.tar.md5 & SS_DL.dll.

After unzipping (GT-I9100G Flasher + Pit), I get the Odin3v1.87 folder & I9100G_omap4_all_20110627_CHN_OPEN_emmc.pit file.

Is it enough for me to start the downgrade process via Odin? Or do I need some other files to complete the downgrade?

3. Does downgrading via Odin from stock 4.0.3 to stock 2.3.6 will void the warranty? So far I have not rooted or installed any custom roms/firmwares on the phone yet.

4. Does downgrading via Odin from stock 4.0.3 to stock 2.3.6 increases the binary count?

Thanks Jayce for the prompt reply. I would consider sending my phone to Samsung Service Centre then.

By the way if I would like to do downgrade with Odin, do I need to select the PIT file? Or I just need to check PDA and select the (I9100GDZKL3_I9100GDZKL3_I9100GOLCKL3_HOME.tar.md5) as well as Auto Reboot & F.Reset Time and leaving the rest uncheck by default?

@Kevin: Factory reset won’t cause any issue to hardware. Do consult Samsung Support for your issue. It might be hardware issue.

Hi again Jayce I have gone into Kies to see what firmware I am using to see if I can install Ice cream Sandwich 4.0 to sort out my problem. The Firmware version i am using is PDA:LPT/PHONE:LQ6/CSC:LPA (CPW). After going on Google and finding out the version is telling me it’s a Rom version from CPW (Car Phone Warehouse.) This is where I purchased the phone from. Does that mean I can’t install or upgrade my Firmware?

Thanks Jayce I have tried to change or upgrade Firmware copying instructions from Video but to no avail. I think maybe because this phone is a contract phone the firmware might be locked. Is that possible

Hi Jayce,

I followed instructions, and after a Passed sign in Odin I unplugged the cable. However, the phone has been blinking ever since, and setup has not started. Any advice please?

just to share experience…my sg2 GT 19100G..i hv upgrade ICS OTA,,,then root it…then use CM9…so kinda hate it..i want to revert back to ICS kernel..during restoration its hang… so unpatiencely i FORCE CLOSE it …DO NOT DO THAT..if it hang always remove the battery….1st…. its still can be restart..but CANT BOOT …so i got panic…on the raya EVE already…the SGS2G got brick…so i send it to samsung support in Seberang Jaya Penang…good thing is by Hari Raya ..i managed to get it back after service..and its firmware and rom a as good as gingerbread new 2.3.6…i really appriciate those tech support help and they even open during hari raya..Thanks u guys..

Jayce:

i am from india and i have upgraded my galaxy s2 to ICS through odin. now when i connect my phone to pc via kies it says “your phone doesnot support firmware upgradation via kies. please let me know how would i restore to stock official firmware and how would kies accept my phone for upgradation. please provide the stock firmware for india as well.
I shall be highly thankful.

привет
помоги мне пожалуйста
я вставляю usb jig а custon binary не становится 0

Having a hard time with this. I got the phone with cyanogen10 and want to restore to stock. Finally got Odin to recognize my phone but now it won’t move past setup connection… Sorry I’m new to all this and have spent all day trying to figure it out. Any chance u can help?

Does this mean it is possible, contrary to what we are told, to downgrade from Gingerbread 4.0.3 to Gingerbread 2.3.3? I regret like a dog I did the upgrade this summer.

hi, do you know which is the latest version of 2.3.6? and how can I download it? I can’t understand the process because it’s my first time to do so.. thank you! 🙂

hi, I used the method that you did but after my phone reboot, the setup always force close… what do i do about it?? please reply asap.. :((

Hi Jayce,

Please let me know where to find the ICS firmware for the Samsung Galaxy S II I9000GXXKL4.
This is a unlocked phone from UK.
Couldn’t find one anywhere.

Thanks in advance.

Regards,
Hemal

Hi Jayce! Will a factory reset change my Siyah kernel back to the stock kernel? I couldn’t find a download of my model to do it over Odin so this is me grasping at straws.
