so my f90bt started doing the reboot problem i went into test mode and looked at the igo folder and everything was corrupted. i tried to delete and reinstall but the files wont delete and i cant copy new files in either. im at an impass. i cant find anything on how to actually reformat my flash disk. can someone please help me!!

so i found out how to format it by playing around on the unit but there is 4 listed drives available for formating. can anyone tell me which one it is.

so i been fiddling around with no luck. ive hit the wall of IDGAF! so im just going to try one of them. worse comes to worse i brick it, pull it out and put my old deck back in for a couple months until i have the cash for a 930bt. i search the forums daily and cant find anything that helps. everything i find skips the explanation of the step im stuck on and noone really seems to be in here anymore. so here goes nothing...

it works!! i formatted the right drive and then whilst search not in the troubleshooting forum but in the mods forum i found a link to a torrent of the files. dl'ed them and installed today with great success.
