Hacking Switch bricked?

[MoveJockey]

Hello.

I followed a tutorial that says restore your emmc boot0/1 and emmc gpp backup to downgrade to an earlier system firmware. I never used a cfw.
Now it doesnt turn on, only rcm mode works.

Any ideas to manage this?

Never used a cfw, then how are you going to restore YOUR nand backups?

I followed this guide but I give up cause I dont find a keys.txt for fw 6.0
If I find a keys.txt could I manage to "unbrick" my switch with these method?

yes, in theory

choidujour is very picky when it comes to keys, it's better to use your own keys dumped with lockpick but if you don't have them, search and search online until it works for you

restore your backups and start from scratch, or better yet, wait for 7.0.1 CFW
