Here are the infos from my device (SM-A500FU):
PLease tell us how to dd PIT and EFS:
PIT: dd if=/dev/block/BBB of=/storage/extSdCard/sm-a500fu/backup/dd/out.pit bs=8 count=CCC skip=SSS
1. How to get the missing items right ?
Reference Post: http://forum.xda-developers.com/show...php?p=52329632
2. Must we save all of those for EFS and is the ending .img OK ?
3. Should we save those too ?
4. And what of the rest is useless ?
