Thread: [BRILLIANTLY SOLVED] Garmin Nuvi 3760 - Bricked?

Aeshong, you're a genius. I was able to see display retro-illumination light on the display in a dark room and turn it on and off.
I also succeded in getting in pre-boot mode (SYSTEM displayed in the mid of screen). However, updater isn't able to install the firmware by displaying the following message:

The GARMIN device is not responding. Please ensure the following and try again:
1. The GARMIN device's Interface is set to Garmin or Host mode
2. The cable is connected to the correct serial port
3. The GARMIN device is turned on

Garmin device displays "Loading..." and doesn't exit pre-boot mode even when I release the finger from upper left position.

FYI, I cleared non vol stat after performing the first, unlucky 3760 fw installation. I suspect that it reverted MTP mode to Auto and I didn't modify it to storage afterward.

Any idea how to progress?

Regards, Rodrigo
