NOTE: The i9100 does not support a separately bootable recovery partition. To install and use TWRP, you will need to install a custom kernel or boot image that supports IsoRec. You can find out more about IsoRec [here](http://forum.xda-developers.com/galaxy-s2/orig-development/isorec-isolated-recovery-galaxy-s2-t3291176).
