DaRippa Posted July 9, 2011 Report Share Posted July 9, 2011 Hi evereyone. I recently wanted to update the firmware of my F500BT unit (EU version). Since I don't have installed any map update I seem to have downloaded and installed the wrong version. I upgraded from 1 to 4, now knowing, that 2 would have been the only verion working for me. Now the unit boots, shows the main menu and says 'System Startup in Progress. Please Wait' (for I have German as language it actually says 'Systemstart läuft. Bitte etwas warten.'). The message never disappears, but I can start navigation, the warning is displayed (with startup message on top) and thats it - no way in nor out. Media section is also available, but is of no use. Is there any way, to install verion 2 or at least restore version 1? I've read lots of threads here and found ways to enter testmode, but it doesn't work. On booting the unit says 'Error MapDBinfo:0x1000 <=> Device:0x0010 AU: 0x0001 EW: 0x0010 RE: 0x0100 UC: 0x1000' and hangs itself. Since I didn't intend to hack the unit I have no backup of any files or folders. Thanks for your replies! EDIT: Would I be able to install the map update CNSD-250FM now? This could help, couldn't it?

whalepirot Posted July 12, 2011 Report Share Posted July 12, 2011 That might work. I bricked mine and messed with it until I got it going again. Now, you know to always backup. I resisted the urge not to. Quote Link to post Share on other sites
STI4Life06 Posted July 25, 2011 Report Share Posted July 25, 2011 Hey Rippa were you able to downgrade the firmware? Quote Link to post Share on other sites
