Update Samsung Galaxy S2 GT-I9100 to Android Jelly Bean 4.3 using CyanogenMod 10.2 Custom ROM

50

The good thing I love about Samsung is, Samsung doesn’t forget its smartphones and tries to bring the latest operating system to its popular and best selling devices. But unfortunately we saw the updates for Samsung Galaxy S2 only till Android 4.1.2 Jelly Bean. Samsung has not decided/announced to roll out any new firmware update for Galaxy S2 until now. Anyways, the other good thing is that Samsung’s devices have a vast development platform and the developers always find it easy to bring the latest mods and custom roms for Samsung devices.

    • @disqus_2jzGlC3hck:disqus Hi, There are two things you can do to resolve this.
      1. Check you device’s version carefully, it must be only GT-I9100 it may not be I9100 G or some other.
      2. Download ”Rom Manager” from google play store, and update you cwm recovery to the latest version using that app, and then try flashing this ROM.
      This should work for you now, Let me know if you still can’t get it to work.
