I bought a JTV 59 a week ago. Plays fine, no issues. Firmware as received is 1.71. So I run Monkkey andf it tells me the latest version is now 1.9. Do the firmware upgrade and it fails with a messager saying Code (80009000) unknown MIDI error.
Spent 30 minutes on the phone with Line 6 tech support (very friendly). Swapped cables, USB ports, etc.... no use.
Suggested that I return to Line 6 for repair (2-3 weeks turnaround time). I was able to roll it back to 1.71.
Has anyone else experienced this? Any suggestions.
Best Regards, Mike
