I have a Samsung Galaxy S2 plus (GT-i9105), running Android 4.1.2 (Jellybean).

I really tried evereything – with Odin, with apps, with other programs. I tried to update with Samsung Kies, but that doesn't work.

I want to install CyanogenMod. I tried with the CyanogenMod Installer, but doesn't work. Now I'm out of ideas. Could you give me any pointers on how to succeed?

  • Hi and welcome to Android.SE! Have you tried using Heimdall to install ClockworkMod? If Heimdall doesn't let you do so -- what error message does it give you? Jul 15, 2015 at 23:55

First: Cyanogenmod is a customized version of Android and NOT a recovery.

Ok, let's move. You should root your device first. Once rooted you can install the ROM Manager App from the Play Store, which will guide you to install Custom Recovery. In order to root your S2 follow this instructions: http://forum.xda-developers.com/showthread.php?t=2663834
