Thank you very much for the tool!
I am able to unpack, modify, repack and flash a Firmware for a Pipo M6 max but I have to use the Windows version for unpacking/packing.
The Linux Version did not run under Ubuntu 10.04 LTS x64.
I extracted the zip-file and make the file "imgrepackerrk" executable via chmod a+x imgrepackerrk
If I try to open it via ./imgrepackerrk
I get bash: ./imgrepackerrk: No such file or directory
Did I miss something or do it wrong?
