From first post:
Pre-Boot for navigators nuvi 5x0 [and zumo 2x0]:

1. Turn off the navigator.

2. Click and hold the upper left corner of the screen.

3. Click and hold down the power button.

If you don't start flash in this 10 sec, your device will no longer be in pre boot.

If you can't read basics info, how will you repair your device?
Posted photos show some text above logo when entering pre-boot, that was the rationale for my conclusion. Did not find any part of instructions -explicitly- saying no indication will be visible on screen. You may want to improve instructions.

Anyway, now I know better.
