Hmm… This is what most of the user don’t like to do ~ hard reset your own phone. But I am going to hard reset my HTC HD2 in the near future. Why? Most of the applications like calculator, Google Maps, Garmin Mobile XT do not able to rotate to landscape mode anymore. Luckily, Opera Mobile 10 which heavily use still working. And HTC album and music player are working fine too. Not sure why my phone behave like this. Maybe I installed some ‘dangerous’ applications… Who know? Anyway, there is the guide to hard reset HTC HD2 that I took from HTC website.
Performing a factory reset via settings
- On the Home screen’s Settings tab, tap Menu > All Settings > System > Clear Storage.
- Enter 1234.
- Tap YES to perform the reset, or tap NO to cancel the reset.
Performing a factory reset using phone buttons
- With your phone powered off, press and hold the VOLUME UP and VOLUME DOWN buttons.
- While holding the volume buttons, press the END/POWER button briefly and then release it.
- When you see a warning message on screen, release the VOLUME UP and VOLUME DOWN buttons.
- Press the VOLUME UP button to perform the reset, or press any other button to cancel the reset.
By the way, do remember to backup your data first before hard reset (if you still can). You can sync with Microsoft Outlook or Microsoft My Phone to backup personal data like contacts, calendar, SMS, tasks. For programs, you need to use other backup application. Usually, I prefer a clean installation after format. So backup data to Microsoft My Phone is enough for me.
I really hate to hard-reset electronic devices. Last time, when I hard-reset company old HP PDA device, the PDA device gone forever and faulty without reason. Haizz…so be careful when hard-reset any electronic devices…
Hey Jayce, thanks for the support you give everyone here. Im sure like me they all appreciate it.
Anyway quick question in regards to a hardreset. If i was running droid on my hd2 (as per all your great instructions), will i be able to just run droid again from sd card or do i have to go through the whole process again?
Hard reset will not remove HardSPL3, radio version and Android on SD card. But your Windows Mobile data will be deleted and back to factory default mode.
Nice info,but the backup think should be at the top,when i have read that part,was already too late.Thanks anyway, i didn t loose too much data!
please i want to make sure that i have the right pereq before i continue…. i have a US version tmobile hd2 and my SPL is 2.10.0000 8g xe radio is 2.10.50.26… my Rom is 2.13.531.1…. please do i need to install or upgrade my rom? do i need to install hspl3? what do i do with bootloader? how is the battery life of nand? pls help me.
What do you want to install?
I’ve coded my phone, using htc hd2 software for adding lock pin code to block the phone. Now the password is not working any more and I cannot use my phone. What shall I do?
Thank you
Just hard reset it. It will load back to factory default mode.
Hey Jayce, If I hard reset my phone, would I finally be able to switch my phone to the droid builds? I was successful one time and then couldn’t do it when I tried again. I just keep getting “error certificate is not trusted” messages when I hit cld & haret. How can I fix this? Thank you

my htc hd2 has locked me out of the phone for some reason it just wont recognise my number code. I have tried the volume up/ volume down trick many times but it just wont work. Other people have also tried for me an still no luck which i cant understand because my buttons were fine when the phone was working. Is there anything else i could try any suggestions apart from the option of putting a hammer through it (which i am close to doing) would be great!
1. Power off your phone.
2. Press volume down button (don’t let go) and power on your phone.
3. It will load into ‘Red, Green, Blue and White’ screen bootloader.
4. Then install Windows Mobile again.
I’m selling my hd2 and its running android. I’m trying to delete everything on the phone. tried the hard reset w/ buttons but it does nothing. My gmail account is still on there and I for some reason I cannot delete it at all. How can I delete my email address from the phone.
Here’s what it says when i try to delete it “Remove Account – This account is required by some applications. You can only remove it by resetting the phone to factory defaults (which deletes all your personal data). You do that in the Settings Application, under Privacy.
Factory data reset does not reset anything.
Maybe you can try wipe data/factory reset in ClockworkMod Recovery – https://www.jayceooi.com/2011/04/20/how-to-wipe-data-cache-with-clockworkmod-recovery-on-htc-hd2/
im having the same issue, except i ‘bought’ a phone with previous owners gmail on it. did you find a fix?
im worried if i reset the phone, *hard or soft* it will remove the aftermarket installed android system, do you know if it will? i know nothing technical about phones, so sorry if this is a dumb questions.
How do i install windows mobile if the screen wont change from red green blue and white?

hi, i just bought a hd2 rooted with android off ebay. the previous owners gmail is set up on the phone. they changed their password and so the phone can not access google or the market for apps, its making me enter a password, but does not let me change the email itself and of course i dont know the previous owners password to get in. i tried to remove that email and it wont let me, says i have to do a factory reset.
my question is, when i do a reset will it remove the android system?
i am not a techie gal, so i have no idea what to do. please someone help me : )
It should not remove the whole Android system. But it will remove all the installed applications and data.
I’m having the same problem but when I do the factory reset the way the phone tells me to it still doesnt delete the previous owners gmail info. I hope the volume up/down trick works.
Nope… still there and I still can’t get into the apps market 🙁 I’m going to cry!
Can you load into ClockworkMod Recovery? Something like this https://www.jayceooi.com/2011/08/15/how-to-install-cwm-nand-android-on-htc-hd2-video/
If can, wipe data and cache then.
Thank you for the great advice , my HD2 had not been working for 5 months , and then i saw your post and it worked ! thx .

Factory reset in CWM then.
