Hello, I have technical assistance and I do switch unlocking.
But, 2 consoles arrived here from people who tried to do the process at home and damaged the console.
None of them turn on and PICOFLY gives the error (*=* No eMMC block 0 read (eMMC init failure?)).
I imagine the eMMC was permanently damaged.
Has anyone managed to recover from this type of problem??

I had an idea yesterday to buy a new EMMC and replace it, but I don't know if that would work. Has anyone already done this?
I'll leave here a link to one I found on Aliexpress:

Link 1
Link 2
Link 3

I would like to do this, but I don't know if it works.
Or if there is a way to recover the damaged one.

Get a emmc programmer and defines emmc condition in that way, most beginner damage trace or just data corruption on boot0/1

FYI you change emmc without original prodinfo partition or keys meaning the console would not able to online or install cartridge game in most case. Kinda pointless IMO

Hello, I have never worked with NAND repair. So I don't have this programmer and other tools, like software etc...
Can you recommend a programmer or kit to carry out this work?

Is there any tutorial on how I can repair the damage to the EMMC with this programmer?

Thanks

From my understanding you can boot into Hekate with just a blank eMMC. That should be enough for Hekate to create a valid partition table on the eMMC and will likely be enough to boot Atmosphere. However, there will definitely be caveats to this. If you don't ever restore a backup of the original eMMC onto the new one, then OFW definitely will never work.

Adding to this: sthetix's video shows him reading a backup from the original eMMC before replacing it with a new one. He is using a UFI Box to create the dump which is a very expensive hardware programmer. I personally own a XGecu T48 which is about a quarter of the price and supports the Switch eMMCs as well. Depending on how screwed the original eMMC is, you may be able to do that, too. Then you could restore that backup to the new eMMC either with the programmer or with Hekate and you'd be good to go.

Possibilities to dump the emmc (if it's not completely damaged)
V1 switch with RCM bug
UFI box or his countless clones
Ft232h with Postal software
mmcblknx or his clones
If you are fine to send the emmc's to me (Germany) I can try to recover the data.

  • Sicklyboy @ Sicklyboy:
    I'm not familiar with the technicalities of the differences between the two versions, but I'm wondering if at least some of those differences are things that you could port over to the US version in your patch without having to include copyrighted assets from the EU version
  • TwoSpikedHands @ TwoSpikedHands:
    @Sicklyboy I am wanting to fully change the game and bend it to my will lol. I would like to eventually have the ability to add more characters, enemies, even have a completely different story if i wanted. I already have the ability to change the tilemaps in the US version, so I can basically make my own map and warp to it in game - so I'm pretty far into it!
  • TwoSpikedHands @ TwoSpikedHands:
    I really would like to make a hack that I would enjoy playing, and maybe other people would too. swapping to the EU version would also mean my US friends could not legally play it
  • TwoSpikedHands @ TwoSpikedHands:
    I am definitely considering porting over some of the EU features without using the actual ROM itself, tbh that would probably be the best way to go about it... but i'm sad that the voice acting is so.... not good on the US version. May not be a way around that though
  • TwoSpikedHands @ TwoSpikedHands:
    I appreciate the insight!
  • The Real Jdbye @ The Real Jdbye:
    @TwoSpikedHands just switch, all the knowledge you learned still applies and most of the code and assets should be the same anyway
  • The Real Jdbye @ The Real Jdbye:
    and realistically they wouldn't

    be able to play it legally anyway since they need a ROM and they probably don't have the means to dump it themselves
  • The Real Jdbye @ The Real Jdbye:
    why the shit does the shitbox randomly insert newlines in my messages
  • Veho @ Veho:
    It does that when I edit a post.
  • Veho @ Veho:
    It inserts a newline in a random spot.
  • The Real Jdbye @ The Real Jdbye:
    never had that i don't think
  • Karma177 @ Karma177:
    do y'all think having an sd card that has a write speed of 700kb/s is a bad idea?
    trying to restore emunand rn but it's taking ages... (also when I finished the first time hekate decided to delete all my fucking files :wacko:)
  • The Real Jdbye @ The Real Jdbye:
    @Karma177 that sd card is 100% faulty so yes, its a bad idea
  • The Real Jdbye @ The Real Jdbye:
    even the slowest non-sdhc sd cards are a few MB/s

  • Karma177 @ Karma177:
    @The Real Jdbye it hasn't given me any error trying to write things on it so I don't really think it's faulty (pasted 40/50gb+ folders and no write errors)
  • DinohScene @ DinohScene:
    run h2testw on it

  • DinohScene @ DinohScene:
    when SD cards/microSD write speeds drop below a meg a sec, they're usually on the verge of dying

    Samsung SD format can sometimes fix them too
  • Purple_Heart @ Purple_Heart:
    yes looks like an faulty sd

    @Psionic Roshambo i may try that with my dead sd cards
