The Samsung Galaxy S2 Skyrocket SGH-I727 will be receiving the Android 4.1 Jelly Bean update real soon and in two flavors: the official version (from AT&T and Samsung) and the unofficial version (via custom ROMs). In order to flash such updates manually and without using OTA, you need to have recovery software installed on your phone.

One of the popular recovery tools out there is TWRP Recovery. What makes it popular is the fact it features a touch user interface, which is a relief from stock recovery or from ClockworkMod Recovery's button-mashing navigation.  Having such a recovery tool is vital as it is the stepping stone in the road to customization.

This guide shows you how to flash TWRP Recovery for the Galaxy S2 Skyrocket I727.
