Nope. Those are not happy messages.
It could be that persist is not used on this or that it's not a normal format.
Or that you trashed it.

That has sensor calibration data (mostly?).
That might not be so important but its absence might be the cause of your problems.

Ok, another test:

edl /u0 /r /psuper /c2048 y

That should make a file of 1 MB.
You can just rename it y.prc and post it as attachment.

Hey, my math sucks.
Or I just forgot that you're UFS.
It's all good. Sec....

Yup, you overwrote super with a zip file.

Lunchtime for me, I'll be back.

[Renate]

Oh, dear.
Updates have the logical partitions but not the correct metadata.
You killed the metadata too.
We have to make that from scratch.

Lemme see...
