Thanks for these detailed instructions, they seem to have solved the issue! I also managed to back up a device running Jetpack 5.1.1 using the same process along with the patch file I mentioned here: Unable to backup reComputer Industrial J4011 on Jetpack 5.1.1 - #5 by astampcv
Quick question on the batches you mentioned - does this mean if I create an image on a Seeed reComputer Industrial today and order another one at a later date that I may not be able to flash the later device with the image from the first device?
If so would I be able to get around this by taking the SSD out of the new device and putting it into the old device to flash it before reinstalling it in the newer one?
One of my reasons for wanting to create a backup is that the latest batch of reComputers we received from Seeed seemed to have some instability when running our software so we were hoping to use this backup process as a way of ensuring the setup (OS, drivers etc) is identical.
