If you own the Samsung Galaxy S2 GT I9100 smartphone then you can now update your phone with the latest Jelly Bean 4.1.1 based custom ROM firmware, as those of xda-developers had just made available the Thebyani software. I know that there are many updates leaked for the SGS2 devices, but the present one is coming with many improvements, bug fixes and extra features, so you might want to check it out. You have the installation procedure explained below, along with the Thebyani features list and with the required preparation tasks therefore, if you want to perform this tutorial just read and apply the next lines.
As you can already tell, the Thebyani custom ROM is not offered by Samsung and also there are no words about a possible Jelly Bean 4.1.1 OTA release for your Galaxy S2 GT I9100. So, by flashing this beta update on your phone you will be aware that some operations must first be completed on the same. This because, a custom firmware is working only on a rooted device that has a custom recovery image installed into the system. Therefore, you must have a rooted S2 with CWM recovery installed. If not, you will not be able to apply the steps from below.
If you do choose to root the OS, then you must know that this implies in voiding the warranty. There are many advantages that come with a rooted smartphone, not to mention that the warranty can be previously regained. For that you need to downgrade to the stock ROM, or to update to an official launch of the Android platform. Of course, by doing that the root access will be revoked and the bootloader relocked. Now, after rooting you must get and install accustom recovery image. You can anytime flash CWM recovery as it is the most popular recovery tool used by the Android users.
