So I learned something about porting, but got a fatal problem. I have no access to IDA (the free version does not support ARM, the other is too expensive
). I searched forums, searched the web and tried free tools. I managed to disassemble the primary.bin file, but probably incorrectly. The analysis is too hard without IDA (and there are only IDA tools here
). I'm sorry, but now I'm unable to make this done. I haven't finished yet, I'm just telling you not to await any progress from me shortly.
