[Q] Urgent Need Kind Help
I am using a docomo SO 02f and recently I have updated it from 14.3.B.0.288 to 14.3.B.0.310, however I regret to do this coz it cannot be easily rooted (such as easyroot v12) and consumes the battery like a monster . Therefore I'd like to unwind it to the previous version but duno how to achieve that. Can anyone here help me with that pls? Step by step instruction is preferred and appreciated for your help.
