Everywhere I check, Api fix is the only suggestion. You say you're stuck on 05, have you tried using the 06 boot loader and binary changed to API_FILE.bin? If this doesn't work, maybe you can try a factory cable load. You might be able to force the 9000 into loading if you start during the boot sequence. Just a suggestion, never tried this myself. I just remember being able to do this with other pansat models (old night rider fix). Let me know how you make out.
