[charlieb]

First brick?

And then I came to the realization that 70% of folks are in here for accident tourism purposes.

Be honest, how many other numbers did you try before you decided on 70%

Theres a small chance that OP is bullshitting you by re-colorizing the picture he made from a simple whitescreen because of the exact same keyboard color. Maybe.

Nah, there's too many holes in that theory, and it's too much trouble for no real gain to be the case, from everything I've read on this thread, and from what a lot of the devs had to say commenting on it, as the thread started gaining traction, it seems like it's unfortunately real, and was partially known to exist previously likely through brick testing (stress tests) to be a thing, which is obvious as early on jjbredesen was able to point out a possible route cause related to the specific issue.

Violete kernel panic code = Bootloader error

Did u make a backup, and can u boot into RCM / run payloads?

May I quote you in the future, please.

Ill probably receive a ton of heat for that lmao but sure.

Heat Schmeat, those who avoid negative attention on the Internet, likely haven't lived. let loose those inhibitions lol

Like many others in this thread, I am backing up my nand as we speak. If anything, thank you OP for bringing attention to the seriousness of modding without backups. Hope you get it fixed man, good luck.

Also, I feel like this is still on topic and may have been answered somewhere else. Sorry if it has been answered but I haven't seen it yet.

We have a way to BACK UP the nand. But do we have a way to restore it? Might be a dumb question but I feel like if we did, there'd be a way to possibly restore an older firmware right? Kind of like how we used to downgrade the 3ds before installing custom firmware.

I got the the same issue 3 days ago, fixed by pressing power button for 12 seconds.

No, the Switch uses a system of fuses to prevent downgrading. You can only install the same or a newer version of the FW.

fuses prevent you from booting older firmwares normally (they should still be launchable via hekate though)
you can restore your backups via the u-boot eMMC UMS mode (which seems to be the cause of these soft bricks for the 1/2 people who have reported it) or via linux (you gotta find a way to make the eMMC not RO though)

Nice. Is there a guide anywhere on how to do that?

I think that is at least 2: 99% and 80% >.<

The switch is alive again, thank you rajkosto for all the hard work and time and for the patch.

And no i didnt faked the picture

 

[rajkosto]

This clever fellow somehow got a program on his computer to try and "fix" the non-compliant eMMC GPT after he had it in UMS mode (nintendo doesn't care so they swap the partGuid and partType fields, as a consequence something that is supposed to be unique, isn't, making it non-compliant), restoring the stock GPT to his switch fixed it (he says the culprit might be the ext2 volume manager from the program he installed to be able to mount ext4 partitions on his Windows PC, that may or may not be the case)

If you also managed to do this, go get gptrestore from https://switchtools.sshnuke.net and run it (Source code available at https://github.com/rajkosto/gptrestore)

If it weren't for this thread, I wouldn't have found that we even have NAND backup tools yet. Time to spend 45 minutes waiting for 29GB to backup onto my SD card. Cheers, m8. Glad your Switch is working again.

I started with 90%, then thought about the people, who might be in here to inform themselves about what happened, so they might not repeat those mistakes - then went back and forth a bit, because none of them should be modifying stuff thats on their nand - based on currently available releases, and settled for 70%.

I admit that I did it by feel and not by actually counting the fingerpointy *haha* posts and the "is this the first *whisperwhisper*" entries, nor the "we should call it VSOD" jokesters. Which I acknowledge is bad, and not at all scientific.

edit: I had also written a paragraph wondering, if the OP could offer people in here selfie opportunities with his console for a small fee, but then deleted it, because I deemed it not necessarily being in good taste.

Maybe a exact description of what did you use to have a softbrick and if you can a tutorial of how did you recover without a previous backup
