Can't restore emmc backup

[progmatv]

Hello! I tried to restore emmc backup on nintendo switch but I see an error from 1st photo. At partition folder USER.00 file have zero byte size. Then I tried restore rawnand backup as a single file, still not working.
If open emmc at tegraexplorer, USER folder don't open with DESC: NO FAT error.
And for last try I open rawnand in Hacdiskmount, dump USER folder and I recieve error (2nd photo)
Am I have bad backup? If I can't restore backup (gamesaves most important for me) then how can I upload clean firmware (with cfw of course)?

Did you resize user partition? Also is the original backup complete?

Seems like you restored a corrupted backup. 010000000000001f is the ns service title and it shouldn't cause crashes.

First dump your prod.keys and mount emmc in nxnandmanager. Format your user partition and see if that helps. If not you need to do a nand rebuild. Use your own prodinfo and prod.keys, generate boot0/1 and system titles with EmmcHaccGen, restore them with nxnandmanager and that should fix your problem.

Thank you for answer! I guess I resized user partition when installed switchroot. And I recently found backup from installing chipmod for the first time but it was created 3 years ago I think it is not compatible with newer firmware.

I want to try your way and I'll write as I try

No that's not works, USER partition's broken. For last try before nand rebuild I tried restore old backup and maybe there is an option to update without turning on OFW? Because backup with 14.1.2 firmware and 19 burnt fuses (17.0.0+) and have error when boot OFW - pkg2 decryption failed! pkg1/pkg2 mismatch or old hekate
And when CFW - a fatal error occured when running Fusee. Failed to find IN1

It helped me to perform a NAND rebuild with a donor dump.

Thank you @randy_w!
