Guest errmsg Posted June 8, 2013 Report Share Posted June 8, 2013 (edited) Just in case somebody needs to unpack official Acer builds for A1, A2, A3 and A4, here is an unpacker for acer_MergedOSFile.bin: GitHub, Win32 build: unpack_acer_mergedosfile.exe (sha1:b4f5a706d4b8244be48df9d11ce1670a09789980, 16K) This is a command line application only. Please note that if you want to flash the .img file with fastboot, you will need to skip first 20 bytes of the image. Use -s option. Usage: ./unpack_acer_mergedosfile [-s] [-f] [-d dir] acer_MergedOSFile.bin -s Skip 20-byte header for some files (enabled for A4) -d dir Use this directory to extract (default ".") -f Continue even if MD5 check fails -h This help E.g in Linux: $ ./unpack_acer_mergedosfile /home/rye/Projects/VFIT/acer_MergedOSFile.bin Checking MD5...
