Friends .
First I would like to congratulate you for the initiative to install the rom in JLB foston FS - M787S .
Well I had problems with my FS - M787s , I needed to install your rom , because by the firmware of my problems , I could not do a backup .
Acquire another FS - M787S , with original Rom working perfectly , plus the accelerometer chip is different . Is mma 7660 and standing with his rom is DMAR06 .
Good not see the problem , unfortunately most of the battery which is with Rom Jely BEAN 4.1.1 , warms the A13 chip and drains the battery very fast .
I made a backup of the original rom FS - M787S which is working perfectly , via ClockworkMod .
More to try to make the recovery of this backup original rom in Rom FS - M787S with JB , the finalikzar the restore and boot , it boots up more FOSTON lock the screen after the video of the car on the highway .
I opened the two FSM- 787s . The only difference is the chip accelerometer that in FS - M787 rom with original model MMA7660 , and the other is DMAR06 .
I would love to be able to leave the two with the original rom foston .
Are there other ways to make an image or backup that can actually restore the Tablet ?
thank you
