Hardware Black screen after update

[ZerroXR]

Okay so I know I'm probably a moron I've likely bricked my switch but please help me..

I had a game that required me to update my software so I followed this guide switchtool sshnuke dot net (sorry if links not allowed its a guide to use with ChoidujourNX)
First time I did it it gave me error code 2168-0002 and restarted my switch lite, it turned on normally. I then figured it must be the only custom theme I had installed, so I uninstalled
it and tried the update again. All steps went fine and the last one said I need to press Shutdown now! instead of waiting 29 secs for reboot so I did.
After that - black screen. Once or twice the SX OS flashed for one sec but that was it.

I deleted everything from my SDCard (well backed it up on my PC) and put the original files I've had on it the day I got the SX OS chip installed.
Still no difference.

What can I do to fix this? Please please please help me.

EDIT: I've also downloaded the latest SX OS beta (3.0.5) boot.dat and replaced it on SD card. No difference.

Ok after very many tries of everything this is what seems to fix it for me:

1. Clean your SD card of all files on it currently
2. Restore your NAND back up folder to your SD card.
3. Download latest boot.dat from SX OS site (my case 3.0.5 beta)
4. Replace the file on SD card
5. Place card back in console
6. Hold power button for more than 15 seconds
7. Press power button once or twice and wait

That way my console finally booted!!!
