This is the full script.
I built this patch on top of 35.4.1, and I’m sure it’s working fine on 35.4.1.
I didn’t verify on 35.3.1, so maybe there are something different between these two versions leading to the error.
Sure. Just run the l4t_backup_restore.func script directly.
You need some trick to set the folder path and move the code out of the function block.
I don’t see why you cannot.
