Hacking Feedback Hardware Am I broke format on mmc chip? And is this even possible to fix?

Can't wipe it, or boot into ofw or cfw. It says something about "tsec keys" and "failed to launch hos". Don't know what to do.

Hi, only if you have a SYSNAND backup. or at least the console keys.

Your attached picture is not clear and can be read.

This is in Tegraexplorer, when I try to use systemwipe.te. Picture says:
"selected sysmmc
[FatFS] Error: NOFAT
Mount failed!".

I have a backup, but I does a backup when my switch not turning on already. So I think my backup corrupted as well. Also I have prod.keys but I don't know what exactly I need to do.

Thanks alot! I really hope that this method can help me.

Thanks for all who help me. But I screwed up really hard. Somehow I deleted whole OS from internal memory of switch and now I don't know what to do...

Or use a backup, or if you are lucky and have console keys use the two tutorials here on gbatemp about recreate a NAND using a donor one.

You think it can help in my situation? Really hope so. Also what keys I need? And how I can obtain them?

Enough, keep this to one thread

Edit: just enter factory recovery mode and you can should be able to restore it. If you haven't majorly screwed the mmc up
