Cerbo bricked - flash fails with "error installing software"

My Cerbo-GX got bricked last night and does not show anything on the display. No updates on VRM and it’s not controlling anything in my setup.

Decided to reinstall the OS with the microSD card. It boots with these lines and then stops:

Searching for installer image…
Installer image found on mmcblk0p1
Creating partitions…
Error installing software

What would be the next step to revive this broken Cerbo?

Presume that you have debug access to the cerbo, and are trying to install a full image, not a .swu image?

It can happen that the rom becomes un-writable, in which case, there is little that can be done.

Thanks @MikeD ! Yes, I’ve used the full zip and flashed it with balena-etcher. No sure what you mean with debug-acces…

Guess this is a warranty case then!

Ok, I don’t use etcher - I found it was not good, but that is just my opinion. I use a linux machine and just use disks to write the SD cards. I use this for the cerbo, Beaglebones and Pi’s. with no problems. - well almost. Disks will not properly unzip the archive before writing it. This can also cause the error you are seeing.

so: Unzip the archive using a standard program, then format the sd card using an image writer that you know is good. then try again.

by debug access: If you have the skill level there is a serial console port inside the cerbo where you can see the boot process go on via a serial terminal. If this doesn’t make sense to you, you can look this up using other small computers - eg beaglebone as an example. I was assuming that you had this given the messages you quoted above, but the debug access has a lot more detail. How did the Cerbo get bricked?

OK, clear! I should be able to get that working and will try another imager-tool. Else, it’s just a warranty claim as this cerbo stopped working during the night. No changes, no updates, nothing else.

Tried different ways but to no reveal. Replace the unit with a new MK2 device and all is working again. Old unit has been returned for repair/replacement.
