I have galaxy S2 which I bought two years and still is in its Prime Condition with no scratches or smudges at all. So Im planning to install New Version of Android OS on it.

I like cyanogenmod So I want to install this on my phone. I have never flashed ROM on it. It still got the same Stock version of Gingerbread 2.3.3

And yes my phone is root-ed

Mobile info

Model No = GT-I9100
Android Version = 2.3.3
Kernel Version =
Build No = Gingerbread JPKH1 

Can someone please tell me what are the pre-requisites to install cyanogenmod

    Have you checked with the CyanogenMod Wiki? It has a dedicated area for the I9100. Depending on which version you want to install, you can check everything there. As this is subject to change with new versions, I won't re-type all the details here :)

Yes - you can install Cyanogenmod for the i9100 S2.

Get the CyanogenMod (nightly if you feel adventurous or stick with the stable since you're new at this) from http://download.cyanogenmod.org/?device=i9100

Also, you'll need to flash the appropriate gApps package from http://goo.im/gapps

I highly recommend you read through the major posts of this thread on XDA

Also, learn how to use CWM or TWRP recovery - Youtube has a number of videos. See how its done, before attempting to do it yourself, and of course - please back up your data to the cloud or to your PC / laptop / external SD card before attempting this and if possible, perform a NANDROID backup so you can revert back to how things were should the unexpected occur and you need to recover.

  • Thanks I will check it in this weekend. But first I have to buy some dumb phone as a backup I mean if I lose my Precious S2. I must have a backup. I will update you about progress. I'm a noob in this flashing thing

  • Try the stable first. Then if you want to try new features and test the cutting-edge versions, use the nightlies.
