Hi Guys!
Garmin Nuvi 265WT, ID 827, software v6.40 , board v3.
My Sat-Nav had a boot loop problem - Garmin logo, brief white screen and reboot continuously.
Could only get Mass storage recognised if I held top left corner of screen.
Managed to flash to v6.10 - still same problem.
Next flash v500 cure (found elsewhere on another Forum) and now all I get is white screen for 8 secs. and continual reboot.
Cannot get into mass storage anymore as screen does not respond to pressure. Does the cure software over-ride the screen pressure points?

Would like to get it working - any ideas?
Have left battery disconnected for about 10 hours, still no difference.
Is Pre-Boot mode via pressing top left corner of screen?

Need repair tool to see USB again.
Thanks
