Hacking SysNand restore failed

[Deleted User]

Hello all,

unfortunately my SysNand restore failed. I restored my original 6.01 Sysnand with NxNandmanger which worked perfectly but Boot0/1 restore fails with the error message: Input type/size does not match output/type size.
Also tried with hekate, same issue.
On top, somehow I disabled AutoRCM and my switch tried to boot OFW which was upgrade to 7.x by ChoiDujourNX. Therefor my fuses got burnt and it ended in a bluescreen.
Status now:
- SysNand (from my backup) on Switch is 6.x
- Boot0/1 (from my backup) fails to install, error message: Input type/size does not match output/type size.
- 9 fuses burnt which means FW 7.xx
- cannot boot any CFW, screen stays black
- cannot boot OFW (obviously as fuses are burnt and boot0/1 does not match) as it ends in a bluescreen
- AutoRCM is working

May I ask you for your assistance how to get the switch up and running. I do not care on which FW, all that matters it that I can boot it up normally again into OFW/CFW.

Thank you in advance for your hints and help.

PS: why i tried to install clean sysnand? I wanted to go online, update to latest FW and add a linked nintendo account to it. Linked Nintendo account was the main reason.

Looks like you'll need mattytrog's custom repair kit.

You must have somehow burnt your fuses before downgrading to 6.0... you were always in for a bad time

open up Boot0/1 partitions in hacdiskmount using your keys. If entropy test flags an issue, your dumps may be corrupt. If not, there is a version of Hekate that ignores sector sizes when writing to NAND.
