Thread: Garmin devices preboot mode

I have read the instructions and my interpretation is that there is no point in doing anything else until I have succeeded to get the device into pre-boot state. I also assume that there will be some sort of message on the screen indicating pre-boot state. Once this works I would take the next step running the software as described.

I have tried to press and hold left upper corner of screen while connecting USB cable (already connected to PC). I have also tried to press and hold screen while pressing power button (which is actually what is specified for Nuvi 50 in the beginning of this thread).

When I accidently formatted by device I also removed the partition through Windows Administration Tools->Storage still thinking it was my SD card. Could this have caused more serious damage than just the formatting?

You get preboot after dragging the .rgn in Updater.exe always pressing left upper corner on the screen, preboot lasts few seconds (4/5 max) so you must have already ticked the USB option and you must be ready to click ok when Updater will see your nuvi.
You don't have any other options, alternative is to send it to Garmin and some $$.
In my Updater.exe thread everything is explained, there are pictures too.
No problems formatting nuvi, cure works fine and if you have files backup, it's a few minutes task to restore it.
