Hacking Switch won't boot. Blackscreen when booting OFW/CFW/Fusee-Primary

[eyeliner]

What made you recommend exFAT?

He had it before.

I made a backup of my backup and then messed with it. So in theory the orignal backup should work?
I just tested the original backup i made with sxos with sxos and it gives me Errcode=00FFFD47.
So my only backup is not working. I guess my switch is useless then?

Did you figure it out? The Error code you reported means that SXOS didn't locate a backup to restore. The directory structure I indicated should help with that.

Cautious approach to introduce less variables that could introduce other potential free radicals in an effort to trouble-shoot. I appreciate it. Some people would take it as advice that they should use exFat, lol.

I know that FAT32 is better but i tried it non the less.

As for the solution you send me. It gave me the same error.
It did not work at first try and now im troubleshooting a bit.
But i have to do sth else now so i think it might take about 2 hours.

So I restored my NAND with sx os and it still boots into blackscreen. I think i can now stop trying to fix my switch lol.

Try using a fresh boot0/boot1.

That's too bad. Strange that you can see at atmosphere screen but nothing else. I think you have autoRCM enabled or you made the backup when the boot 0/1 were dirty.

 

[Hochgeschwindigkeitswolke]

Yeah AutoRCM is definetly not enabled i made sure about 100 times.

Yeah that seems quite plausible. Too bad.

Tell me something, yo... You tried to downgrade?
What about if you wait a few in that black screen, press power to wake the system and press volume up or volume down? Or plug the charger? Any icon on screen?

Yeah already tried everything you just said. And everything that has something to do with the original firmware does not work, so also no indicator that the switch charges. I only see charging in Hekate.

If the original Nand is the culprit, it's because:
themes, brick code or a messy downgrade. Try to rebuild your Nand like this: https://switch.homebrew.guide/usingcfw/manualchoiupgrade.html
Update to latest.

Cross your fingers, all 21 of them.

EDIT:
also, read the very last point in that guide.

Good luck, mi amigo.

Well i also tried that and i still have the same blackscreen.
Maybe i really toasted anything inside the switch although i dont know how.

There's something you are not telling. The Switch doesn't simply refuse to boot. That's almost impossible.
Disable AutoRCM
Take out the SD
Boot without payload

Yeah i tried a lot of things before i made the original post. Because i didnt know what to do i made the post.
And really. Disabling AutoRCM and booting without sdcard really just ends in a blackscreen.
If there is anything im not telling you it is because i dont know.

Can you boot into maintenance/recovery mode?


In order to enter Recovery Mode, the following combination must be performed:

• With the system powered off, press and hold Volume Down + Volume Up;
• Press the Power button while still holding Volume Down + Volume Up;
• Let go of the Power button and keep holding Volume Down + Volume Up until the maintenance applet shows up.

Already tried that but jsut to make sure i just tried it again and it really just does nothing.
Just a blackscreen.

Should i try to load android on my switch? Maybe i can test some things there, like ram etc.

I honestly don't think it's a H/W error. I believe it's a F/W issue or user error.

As I was saying boot0/boot1. I got the same black screen on emmunand because of a dirty boot0/boot1.

It sounds like this is the issue. How did you clean your Boot0/1?

Does OP know what F/W version the backup is?

 

[Hochgeschwindigkeitswolke]

My backup Firmware is either 11.0.0 or 11.0.1 bit i think its the latter one.
And how do i get a clean BOOT0/BOOT1 ?

Hi Hispeedcloud

Don’t know you read my last post. But to be sure, did you tried to boot without entering the RCM Mode ? Boot the stock system, just normaly. No jigg using, no payload sending.

It sounds weird, because you told, that you were working on the heatsink components before. After this, the Switch was working fine first, then it was entering the standby mode and going defect.

A few days ago i changed a mainboard on a Switch. While reassembling i don‘t connect the daughterboard with the gamecardslot correctly and the Console stuck on the Switch bootlogo. After i fixed this, it worked fine.

For me, your problem sounds like it has to do something with your work before. Did you checked all the connections and that everything is clean ?

Greets, Snap.
