How To: Flash / Install JellyBam ROM On Samsung Galaxy S2 [GUIDE]

Owners of the Samsung Galaxy S2 GT-i9100 have a tough choice to make when it comes to installation of custom ROMs since there are so many available. Wouldn’t it be nice if the features of multiple ROMs could be offered in a single ROM? XDA Developers’ member iGio90 has made this possible by introducing the JellyBam ROM. This new ROM combines the features of AOKP, PanaroidAndroid and CyanogenMod.

The ROM brings a vanilla UI and allows you to switch between various interfaces. The TouchWiz 5 skin makes the UI look like you’re using a GT-i9300 as well. In this tutorial you will learn how to install this new ROM on your device, but you should read over a few pointers first.

The ROM guide is specifically for the Samsung Galaxy S2 GT-i9100 and is not for any other variants produced by the company. You should also charge the battery up to an appropriate level to avoid any power outages during the process. Disabling any security softwares that may interfere while the process goes on is recommended. You should also backup any files that you consider important. Your phone should have ClockworkMod Recovery (link) installed and must be on the XXLPQ firmware. Lastly, follow every step at your own risk as we won’t be responsible for any damages if anything goes wrong.
