RB2011UiAS-2HnD doesn't boot after configuration reset

Mon Nov 22, 2021 10:16 am

I've did everything over the serial console. The plan was to upgrade software and then reconfigure the device.

However, in the middle of the process it broke. I updated RouterOS, issued a configuration reset, and it isn't booting anymore. The complete console log is attached below:
[admin@MikroTik] /system package update> check-for-updates

   b - booter options
   t - do memory testing
   x - exit setup
What's going on? How to repair this?

I admit, I must have been updated RouterBoot as well, but now, are there any options besides Netinstall? I am quite remote to this system, if it is possible to fix without Netinstall, it would be nice. And, if this is impossible, how do I proceed with Netinstall? I am very confused because it booted with the new RouterOS once, and won't boot after configuration clear. What increases the confusion is that I selected the long-term channel to update (it was named bugfix in the old RouterOS). This router was running RouterOS 6.40.3 until this update, showing no obvious signs of problems.

I fixed that RouterBoard with Netinstall (there happened a Linux version, tadam! Helped a lot). However, I am still hoping somebody explains what was the problem.
