Hacking 7.0.1 Downgrade Brick

[damononeil11]

I attempted to recently downgrade my switch from 7.0.1 running Kosmos 11.1.1 to 6.2 using ChoidujorNX. For whatever reason it bricked ! Basically if i booted up RCM and inserted payload it would bring up the Kosmos atmosphere logo then the nintendo logo but then go black screen. Now after erasing SD card and rebuilding it with nothing but Hekate i can get it to RCM and Hekate but don't know where to go from there.

What i have access to:
1. Full backup while i was on 7.0.1 BOOT0 & BOOT1 & RAW.
The problem with this is i've put those files under the restore folder and when I click restore in Hekate it says 'Error 4' failed to locate but I can see that it's in the right location.
2. I can fully access Hekate which includes downloading keys & everything. I know that the switch isn't completely bricked and that I can fix it, I just don't know how.

My question is this: What do I need to do in order to rebuild my switch in either 6.2 OR 7.0.1. I don't care about losing data or if it's CFW or OFW, I just want my switch to not be bricked anymore, I can rebuild it from the ground up if i need to.

If someone could please suggest something that would be super helpful! It's infuriating seeing the Nintendologo load and not work. The only reason I attempted to downgrade to 6.2 was because I won a SXOS license giveaway . If someone could also tell me how it bricked that would be helpful because I have no idea what I did wrong. AutoRCM can be enabled or disabled as well if that helps. Maybe I need to boot something? I'm new to CFW so would love some help

Much appreciated!!!

[UPDATE]: So I've managed to restore to 7.0.1 via BOOT0 & RAW but now I can't boot into CFW, how can i fix this?

SXOS should be compatible with 7.0.1. No need to downgrade anymore.

Double check that the backup is under /backup/<emmc s/n>/restore/. The files need to be named rawnand.bin and boot0 and boot1 without any file extensions.

Make sure that it really is in the correct folder (backup/correct_rng_number/restore).
This is how to rebuild your NAND.

What's the '<emmc s/n>' part of the folder directory?

The serial number of your emmc. that should be the only folder inside the backup folder on root.

Thanks! It's restoring now, fingers crossed in can actually boot when it's finished
