Samsung Galaxy S2 News UpdateGalaxy S2 users can still upgrade Samsung's 2011 flagship device, SGH-T989, T-Mobile Model. IBT has provided a tutorial on how to update the device to Android 4.4.4 KitKat AlpineROM.

Make sure the device is rooted before going forward for custom ROM installation.
This new AlpineROM Android 4.4.4 KitKat firmware has to be installed on the Samsung Galaxy S2 SGH-T989 (T-Mobile ) variant only; if tried on other devices, it might get bricked [To check your device model: Go to Settings >> About phone >> model number]
Installation of custom ROM requires clearing of memory in the smartphone, so make sure to back all the data by installing Clockwork Mod (CWM) Recovery/ TWRP in the smartphone.
