Thread: Nuvi Pre-boot Mode

i've had a frustrating time trying to get a nuvi 550 into preboot mode. Follow instructions for this model but all i end up with is the calibration mode. Anyone with a Nuvi 5xx come up with a reliable way to get these into preboot mode?

I have a Nuvi 1350 that I can't get to recognize in USB mode.
Where do I get updater.exe and a good firmware file to load to it. Preferably, I'd like to restore it to factory state.
Thanks!

My unit isn't bricked. Everything works except it won't be seen by my PC to do updates.
(I have 4 units, all with this problem, one is pin locked and I don't know the pin my sister used and she doesn't remember it, and lost all paperwork in Sandy when her house was washed away, one has a white screen, and the last one works but won't charge or access usb.)
I can't get into any diagnostic screen that lets me turn on the mass storage option instead of auto detect, and using updater.exe says that there are no updates for my unit. I think the firmware is corrupt and I want to wipe the unit and reload it with the factory load. But, can't get into USB mode to even start.

OK, so I couldn't get any of the fixes to work, couldn't even get my unit to be recognized by my PC. But I left it plugged in to a charger for a couple of weeks - AND IT CAME BACK TO ITS FULLY NORMAL & OPERATIONS STATE. There is no rational explanation for this I can imagine - other that just dumb luck.
