If you want to install the latest Android 4.4 KitKat custom ROMs on the T-Mobile Galaxy S2 SGH-T989, you MUST have the latest CWM Recovery 184.108.40.206 or later.
If you don’t, your install will simply fail.
So, how to update?
I made it really easy for you guys so all you have to do is install a zip file using your existing CWM Recovery. Once installed, simply reboot into recovery and you should see CWM Recovery 220.127.116.11.
