Rock64 don't boot

[zet_lab]

After the next (last) update, the system does not boot, there is no ssh access, and the monitor does not turn on.

I just didn't install updates for three weeks and decided to update yesterday
What should I do, re-install the system ?

 

The loader is located on the sd card, and the system is on the hdd, using the 4.4.x kernel
