MOX bootloop upgrading from 6.4.4 to 6.5.2

Hi! I tried updating my MOX to 6.5.2 yesterday and it ended up in a bootloop.
I managed to restore the 6.4.4 snapshot and it worked again.

I have an Omnia too but now I’m afraid to update it :smiley:
Any ideas/tips how to solve/debug it?

Thanks!

If it’s really a bootloop, then a 1.8 V serial cable…

Which (unlike the covers) is not officially distributed by Turris project.
