3 years of Avic f900bt relooping

[crywolf]

Hello, everyone. I have an Avic f900bt and it's been 3 years since I have had a properly working unit. I have tried so many different techniques throughout the years including going into test mode and downloading the hybrid 4.01 files, but I kept receiving a errors. I have also tried deleting the gps.para files and doing a reboot, but it still did not work. I have had this problem for 3 years and I just cant take it anymore! I know some other users have had this issue before, but most of the files on here were either old and/or deleted. Also, when the unit reboots, the "system startup in progress" appears and does not go away until it reloops, so I can't get into the settings. The system startup notification was never there until after I tried doing the hybrid 4.01 files. I'm not sure how to fix this and any advice would be greatly appreciated.
