Odin3 is a PC application that was designed to help us update Samsung Android phone firmware. You can install stock firmware and kernel with Odin3. You can also use it to root Samsung Galaxy S II too. Therefore, you are able to flash CF-Root into Samsung Galaxy S2. It is a must have tool if you like to try custom firmware. And get more juice out of your Samsung Android phone.

Note – Do ensure Samsung Kies is not opened or loaded in system tray when using Odin3.

As my i9100T is different from i9100, there are less methods for rooting it.

Hi JohnJohn, install Samsung Kies (it provides USB driver that Odin needs). Then try again see.
Hi Jayce,
I have Galaxy S I9000 with Android 2.1 and would like to update it to 2.3 at least – can be higher if it is possible. I tried KIES but I see that there is no update for my device all the time. What you can advice ?
Artur
Hi Artur, please consult Samsung Support. There should be Android 2.3.6 firmware by now.
I have SHW M180S. This shows Upgrade on display. Does not go further even if i re-boot it displays the same. Odin does not respond or read the device. Please advice.
Sorry Rizwan, I don’t have this model. No idea. Please consult others with this model at XDA Forum.
