Hello!

I chose inappropriate firmware for startup and now my switch can't start (booting terminates at linux kernel start).

According to documentation it's possible to enter bootload menu and choise right firmware for startup.

The problem is that switch doesn't reach bootload menu phase (it goes after kernel start) in booting so I am unable even to enter it.

How can I recover switch? Is it possible to enter some service menu from bootrom (not bootload) to choise or download right firmware?

firmware bootrom bootload
