Apologies if this has been asked before, hacked my switch about 8-10 months ago (haven't touched it in a while).
My switch was on 6.x cfw previously updated with choi. my backup was 3.x. I tried to restore my NAND and disabled AutoRCM, my jig didn't work and it accidentally booted and is now showing 8 burnt fuses :( I'm assuming I now can't restore to my clean nand that had 4 fuses? man I'm annoyed for being so dumb. I really wanted to goto emuMMC. with CFW and OFW on separate partitions.

yes I did boot0 and boot1 then eMMC RAW GPP, just trying to restore again with eMMC RAW GPP (apparently Hekate states this combines boot0 and 1) latest Hekate

Guy's im really stuck, tried everything. even used hacdisktool but my entropy is failing on SYSTEM and PRODINFO. Im at a complete loss been at this for like 8 hours plus, should never have listened to the guy on discord new it prob wasnt safe to try to restore nand with a fuse mismatch :(

What was the firmware and fuse count for the NAND backup you made, and what was your current firmware and fuse count before restoring.

NAND backup was from 3.x, 4 fuses. last year I used Choi to update to 6.0.1 without burning any and ran CFW happily.
Decided I wanted to restore clean NAND, turned off Auto RCM, jig failed and I was left with 8 fuses.
Guy on discord said you'll be fine just restore....after restore can't boot anything from hekate not even atmo.
Tried going into Hacdisk, some biskeys pass entropy but not biskey1.
At a complete loss now on what to try next. It's my own fault so not blaming anyone but sucks.

The system refuse to boot due to too many burnt fuses, what you can do is try to rebuild your NAND with Choidujour (PC Version) to firmware 6.2 or 5.1, 5.1 seems to work for some people that attempted to restore to lower firmware.
