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?

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.

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 You can only install the same or a newer version of the FW.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?

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.

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

    also gonna install twilight menu in my r4 flashcard
  • Psionic Roshambo @ Psionic Roshambo:
    One thing that just occurred to me.... The sound on the 2600 sucked less back then the harsh sound we hear now is from infinitely better speakers we have now, back when the 2600 was new speakers produced a almost muffled sound, like CRTs made old graphics look slightly better.
  • Psionic Roshambo @ Psionic Roshambo:
    I wonder if I could recommend that to some emulation devs that perhaps the sound could use some smoothing out to simulate those old TVs
  • Psionic Roshambo @ Psionic Roshambo:
    I think a few of the early systems could benefit from that, at least up to the 8 bit generation, by the 16 bit generation I think TVs had gotten a lot better in almost every way

    it says it only works for the original R4, R4i Gold (r4ids.cn), R4iDSN (r4idsn.com) and Acekard R.P.G.

    Just give it a try, but honestly if you have a 3DS you can play DS games without a card just off the internal SD card
