Restoring img file to eMMC - GloriousCoffee - 08-08-2020
Hi
I ran update/upgrade on my debian installation on eMMC yesterday which resulted in the system not booting anymore.
I have a backup image file of the eMMC which I did with gnome-disks but after booting a system from USB and trying to restore the image to eMMC the process is stuck on 0.0%. First I thought it might be calculating something, so I left the computer on all night, but when I woke up it was still at 0.0%. Is there perhaps some other way to restore the image to eMMC ? I don't have the USB->eMMC adapter unfortunately, otherwise I would have tried it to. Installing LUKS debian was a bit of a hassle, so inputs are appreciated if I can get it up and running again without having to go through the whole installation again.

try using dd in terminal instead of something like Gnome Disks.

I'm trying with dd now. Doing: dd if=/pathtoimg of=/dev/mmcblk1
I can see in 'top' that dd is running, but the program isn't outputing anything. Similar to how gnome-disks did (could also see it running with load in top).
Never used dd before, is it normal for it to not have any output during operation ?

Nvm my question, I aborted it and saw 40gb copied so I guess its working quietly.

add status=progress in your dd command next time so you can get some feedback. Without status=, there is no feedback(unless you issue a -USR1 systemcall in another terminal)
dd if=/pathtoimg of=/dev/mmcblk1 status=progress

Thanks ya'all
Restoring with dd worked like a charm.
