I installed the Overcome_v3.1.0_KRATOS_NoWipe. I have a Samsung Galaxy Tab GT-P1000.[australian] the Overcome ROM is great I am very happy with it . Unfortunately I can't do backup
I have a problem with doing backup. but I can't do backup with ROM Manager (Premium) with overcome ROM
When I try do it. The screen gos funny [weird lines on screen]

is there other app to backup for overcome rom?
I can't do that [Release power button about 3-5 seconds into the hold] because I am disabled guy. my hand is not able to do that

is there app can do that automatically ?

please help
