Hm, I seem to be suffering from the same issue. Vero 4k+ will no longer boot up (blank display, no ssh).
Timeline of what I did:
- Successfully upgraded from 2020.10-1 to 2021.08-1 via
apt dist-upgrade - After reboot FullHD was no longer an option in Video output. I was limited to only 480p/720p. Before the upgrade it worked fine.
- Tried to set output to default to FullHD. After reboot same story, no FullHD only 480p/720p.
- Since the default setting didn’t work, I forced output to FullHD.
- After reboot there was no more display output. Waited for half an hour and SSH did not come back (device was not assigned a new IP, checked on router).
- Tried to reinstall, but got nowhere. I prepared a USB drive with the image, it mounts just fine on PC (three files on the root of device), so that seems alright.
All I can think is that I somehow corrupted eMMC with forcing output to FullHD :\ Would appreciate a DM with instructions how I can debrick it. I have access to Linux and Windows systems.
Cheers
