Hello All, I am on the LATEST UHMS8 Android 4.1.2 (LATEST, FEB 26) on my S2 (came though all the official versions prior). Now all that I want is to, flash my S2 back to XXLSJ Android 4.1.2 (because no official JB performed close to XXLSJ in stability/battery endurance through my experience with it, even the latest one.period). I am all ready with the leaked XXLSJ Android 4.1.2 package and Odin, Please advise on 1) Any issues there to downgrade to XXLSJ from official UHMS8? 2) Any other precautions and is it a safe move? 3) It's better to do a full data wipe prior TO re-flashing XXLSJ isn't it? How to do that? 4) My UHMS8 is rooted with Siyah-s2-v6.0b4, I may lose root no worries, OTHER CONCERNS? I don't care my apps or anything, will care to reinstall them over again...all I need is the outstanidng performance offered by XXLSJ!! Waiting for an expert's word to BEGIN!
