Hardware Switch hard mod NAND dump, with Low Voltage eMMC Adapter.

[FXDX]

Hey, I'm looking to recover save data from a fully dead switch (I have all the keys etc. from the console). Am I understanding correctly that I should be able to use the SD card reader I currently have + the Low Voltage eMMC adapter to do a full NAND dump but the only issue is I won't be able to dump BOOT0 or BOOT1? That would be completely fine for me as I just need the USER partition.

Got a living dex on Pokemon Sword that I was pretty sad to lose (really shitty that they don't let you do cloud saves for Pokemon but I understand their reasoning even though I'm sure they could come up with some way to make sure it couldn't be abused to dupe pokemon) but if I can get the USER partition from the NAND that would be perfect.

Try mmcblkNX device.

Wow that looks a lot easier for the same price, can't believe I never found that. Thank you!

Thanks again for the recommendation. I had already bought the Low Voltage eMMC adapter but I ended up buying the mmcblkNX too when you mentioned it. The Low Voltage eMMC adapter came yesterday and it wasn't too hard to set up, took 15 mins or so to solder it all up and it dumped the NAND at around 5/6MB/s.

It's funny because the mmcblkNX arrived today and it's so much easier and better, I wish I hadn't done it all yesterday it took so much longer. Literally just plug it in and install the driver then it dumps at 20MB/s.

Well at least I've finally got my saves back though and they're now backed up to google drive

Great thread. Can't believe I missed this info for 2 years. Just ordered mine

Were you running Linux? How did you acquire the driver? My system doesn't even recognize the device as being plugged in. I've tried it in Windows & Ubuntu

I used the drivers linked here: https://gbatemp.net/threads/emmc-reader-for-hac-emmc.584027/#post-9408815

Windows 10

I'm guessing you had zero trouble using the exploitee board, but can you give me some pointers. I'm testing the process with a good Switch eMMC module that I can read just fine with the mmcblkNX adapter, but no luck with the exploitee. I've tried both a working Switch eMMC module and a SD card and neither work with the exploitee. What SD card adapter did you use, I have the recommended Transcend TS-RDF5K?

Yeah I had no problems using either board. I'm using an SD Card reader I got that was recommended for 3DS Nand dumps a long time ago here: https://amazon.co.uk/Anker®-Reader-RS-MMC-Support-Warranty/dp/B00LFIXC8I/

I would check your solder points with a multi meter maybe, from what I remember I just dumped it the exact same way as I did with the mmcblkNX adapter.

Aliexpress.???? Is there others tool to read nintendo switch mmc chip i have tenssy... And ps3 sescon reader pll... And pic raspberry... Or just only this reader????

Wow - are you saying that Anker reader can read boot0/boot1? That's super hard to find in a generic adapter, and very handy if so. Did you use it with Windows/Linux/macOS?

No, they acknowledged not being able to dump BOOT0 and BOOT1, they only needed to recover saves from the USER partition.
