ImgRepacker builds incorrect image
Help me please.
I use ImgRepacker 2.1 with Allwinner A10 ROM for chinese "noname" tablet with Android 4.0.3 ICS.
ImgRepacker unpacks ROM correctly but then repack ROM incorrectly.
I made an experiment.
I unpacked ROM and then repacked it without any changes.
Tablet doesn't boot with the re-assembled ROM.
I compared the old and the new ROMs. Both files are the same size but they contain 81 differences. These differences are:
1) One big block from offset 0050 to 03FF (944 bytes)
2) 40 blocks of 48 bytes. The 1st of these blocks begins at offset 0430 and the others repeated every 1024 bytes.
3) 40 blocks of 720 bytes. The 1st of these blocks begins at offset 0530 and the others repeated every 1024 bytes.
