a couple of months ago I reported an issue that my C2 stops installing your “DietPi”-updates.

Now the C2 is completely broken !? No Kernel Heartbeat LED is flashing [red, constant blue] no network or HDMI response. It was just a reboot

Well, I started first to analyse the eMMC, made an Image with dd to my SDcard but it's also not bootable. Boot partition broken ?
I started from scratch with your latest image on a second SDcard, restoring my system data etc. – everything works fine. Reboots and updates are also working as expected

Now I need my fast storage back


Do you know how to fix that ? SDCARD is OK eMMC not.
I tested the Ubuntu Version from Hardkernel, but here are no problems to reboot.
Many thanks for your advice, Bob.
