Hello,

 

I just apt upgrade-ed my Armbian 25.5 from mid-August to 25.8.1 and it doesn't start after software reboot. It is usually headless, I plugged it into a monitor and all I get is a uboot logo in the top left corner. No message, nothing.

The board is the Rockpi 4A. The system is on eMMC 😩

 

What do I do now to at least roll back ? At worst make a browsable copy of the eMMC ?

 

Thanks!

Antoine

If you're still able to boot from microsd (which should be prefered over emmc if Armbian uboot is used) you can chroot into the system on eMMC and downgrade packages, either manually (apt/dpkg) or with armbian-config.

Can I just follow the Debian rescue chroot tutorial ? (with appropriate partitions)

https://wiki.debian.org/RescueLive

I suggest booting from µSD and then making a copy of eMMC to somewhere and reinstall after that.  You can then restore whatever you need from your eMMC backup.  Most likely that will be vastly less headache and much higher chances of success.

Now the issue is it doesn't want to boot from SD (eMMC unplugged). I bought a brand new µSD as a last resort but nothing.

I get a fast double blink on the status LED. Tried Armbian_community_25.5.0-trunk.131_Rockpi-4a_bookworm_current_6.12.16_minimal and Armbian_community_25.11.0-trunk.273_Rockpi-4a_trixie_current_6.12.49_minimal.

 

Where can I find old Armbian-supported builds ? Because I'm sure those work. I'll try the last supported build and report. (can't delete this post)
