Hacking Nintendo logo followed up by a black screen after NAND restore (fixing bricked software)

[KingPieter]

Hi guys


A couple of months ago my Switch got software bricked due to shutting off (probably crash) during an official nintendo update. A week ago I found a tutorial (link down below) of a guy who fixes his software brick by restoring the NAND on the system.

I've injected the necessary payloads (TegraRCM) to dump my biskeys. I've wrote the boot0.in and boot1.in to my nintendo Switch's memory and assigned all the necessary files to it with the complementary keys.

Normally the system would boot fine but when I tried to boot it, it shows the nintendo logo for a brief moment followed up by a black screen. The only way to exit this is by shutting off the switch through the power button and rebooting in RCM.

I'm kind a out of ideas atm and I might think that I bricked my nintendo switch even more to be honest...

Do you guys have any advice on fixing this problem?

All help would be appreciated


Thanks a lot,
Pieter

Does your switch have AUTORCM enabled? If not, you have Nintendos official recovery which you can use to download and probably flash the newest update.

You can access the recovery mode by holding the volume + and - at the same time while powering up your console.

Here you go:

Yeah I've put my switch into autoRCM mode. Can I just disable it?

Yeah, you can disable it the same way you enabled it.

I've tried disabling RCM auto. The screen just stays plain black upon booting attempt :/

Try holdin the power button for 20 sec to completely shut down the console and try again, it has to work

 

[KingPieter]

Nope, it won't even boot up anymore... pff I'm so sick of it hahaha

Did you try removing your game cart if any? I had the same problem.

 

[KingPieter]

Yeah the game cartridge slot is empty. It won't boot at all

Does flashing a firmware with Choidujour (not choidujourNx) in Rcm mode work?

 

[Kafluke]

Are the boot0 and boot1 files you injected from the same firmware you're currently on

I tried generating a firmware through choidujour through my pc but I can't seem to get it working. My keys.txt isn't right for some reason although I get them from my own switch.

No it's a downgraded version of the firmware (5.0.1). Not quite sure if that's the problem...

If so, is it possible to get an earlier one from the internet or choidujour (pc version because my switch doesn't boot)

 

[Kafluke]

Boot0 and boot1 have to match your current firmware.

Hmm okay, I've looked up my burnt fuses through Hekate and they're 12 in total. Which means my switch would be on firmware 9.0.1. But is it even possible to get those boot files from the internet?

If you look enough for it, you'll find it.

Are they console unique?

 

[antiNT]

As far as I know, firmware versions aren't console unique but wait for confirmation from another person as I'm not really sure.
