Thread: NEED HELP: nuvi 2455LMT can not connect to PC, after being formated

I finally get it back, also I lost some of saved stuff. Thank you very much. The tutorials are very helpful, especially your preboot post and the step by step unbrick guide, and certainly the garmin cure software. Thank you all very much.

The step of flashing is very tricky and I have to switch between usb cables multiple times and press the corner very carefully to get it in preboot mode. Maybe I should get a better cable.
