This is a guide for save a replaced or dead emmc Nintendo Switch consoles fully noob friendly step by step.
This gonna take a while, you need to be patient or persistent enough.
And you can"t go online but you can use card games, homebrews, pirated games too.
Everything you need to save your switch is in the NSW DEAD EMMC Repair pack


Special Thanks to Adran_Marit for the pikafix pack and guide.

Requirements

To follow this tutorial you will need a few things:

Your bricked consoles prod.keys
Your bricked RCM vulnerable switch
A replacement emmc chip
A working donor switch
A computer/laptop with x64 Windows
My NSW DEAD EMMC Repair pack
prodinfo_gen download the latest and use it in step 75. instead of the one in the pack if you want to update to 14.00

1. Download the NSW DEAD EMMC Repair pack from the requirement on top and extract it to your desktop or somewhere you want.

2. From the USE IT ON PC folder install the dotnet-runtime-3.1.23-win-x64.exe

3. From the COPY TO SD folder copy all the files and folders on the root of the dead switch sd card.

4. On your sdcard mark all the files and folders / right click / properties / special / untick the ready for archive, press ok and apply.
you need to do this every time you copy something on your sdcard.

5. Inject the Lockpick_RCM.bin from the USE IT ON PC\payloads folder with tegrarcmgui on both the dead and working switch.

6. Select dump from sysnand, when it finished press a button and select reboot to rcm.

7. Inject the hekate_ctcaer_5.3.4.bin payload on both switch.

8. Go to Tools / USB Tools / SD Card

9. On the sdcard of your dead switch go to the switch folder and copy the prod.keys to your desktop to a folder name dead switch keys, do the same with your working switch and make a separate folder for that prod.keys too.

10. Unmount your sdcards in hekate go to Tools / Backup eMMC do the eMMC BOOT0 & BOOT1 and eMMC RAW GPP too.

11. After the backup finished remount your sdcard and save the backup folder from your dead switch on your pc somewhere.

12. Go into the backup folder and you will see a similar folder to this 5b4d2a82
in that folder there is the rawnand and the boot0/boot1 files. after copying the backup folder to your pc from the dead switch you can delete the contents of that folder.

12. In the folder 5b4d2a82 you need to create a restore folder and you need to copy all the files from you working switch backup/5b4d2a82 folder to your dead switch.

13. If you finished the copying unmount your dead switch and go to tools and do a Restore eMMC

14. If the restore finished close it, go to USB Tools

15. select "eMMC RAW GPP" (sysNand) - Set read only to off

16. Open NXNand Manager from the USE IT ON PC\NxNandManager_v5.1_x64 folder

17.Press Ctrl+D or press File > Open Drive

18. Choose eMMC GPP hekate

19. Press Ctrl+K or Click Options > Configure Keyset > Import keys from file

20. Choose your dead switch prod.keys you copied to your desktop in the dead switch keys folder

21. Press Save
You will notice it will say Bad Crypto and Keyset Needed, this is normal.

22. Right click on Prodinfo then click on restore from file

23. Choose PRODINFO.bin from USE IT ON PC\Nand files folder.

24.Press yes on the restore prompt

25. Close the transfer box

26. Repeat Steps 22 - 25 for the ProdInfoF, Safe and the other partitions
Do the same restore process for the BPKG2 partitions too
PLEASE DON'T TOUCH THE BOOT0 and BOOT1 in the NxNandManager these two need the etcher later

27. Press Ctrl+K or Click Options > Configure Keyset again

28. Click on clear keyset

29. Choose your working switch prod.keys from your working switch keys folder on your desktop

30. Click on save

31. Right Click on USER choose Decrypt & Dump to file save it somewhere on your pc.
you need at least 60gb os free space for this trick, and be patient this will take a while

32. After it finished you have a user.dec file

33. In the NXNandManager click on file and close drive

34. Click on file again > choose drive and then select the user.dec file

35. Press Ctrl+K or Click Options > Configure Keyset again

36. Click on clear keyset

37. Choose your dead switch prod.keys from your dead switch keys folder on your desktop

38. Right click on user, and choose encrypt & dump to file
now you have a user.enc file too, you can delete the user.dec file to have free space

39. Click on file again > choose drive and then select the user.enc file

48. Click on file / Open physical drive and select hekate eMMC GPP

49. Double click on system, install the driver and mount the partition to a drive letter
in top you will see Bis key 2 crypto upper and tweak lower, now you need your biskey2 from the dead switch prod.keys

50. Open your dead switch prod.keys with notepad and copy the line:
bis_key_02 = 40ac3d379c83b2fccdbb7e8b4906a099a6e7926c47cc415ae32c22f823eeabbe
this is just an example from my switch, every switch have a unique biskey2 and others.

51. you need to cut the long line in half like this
40ac3d379c83b2fccdbb7e8b4906a099 - a6e7926c47cc415ae32c22f823eeabbe

64. Click on Flash
if it ask anything just press ok or continue

65. Unmount "eMMC BOOT 0" and Mount "BOOT 1" - you may need to unplug the switch from the usb and replug it to continue

ENJOY!
For the step 4 (4. On your sdcard mark all the files and folders / right click / properties / special / untick the ready for archive, press ok and apply. you need to do this every time you copy something on your sdcard.) you could save time, doing that on the downloaded zip BEFORE uncompresing it, the un-compresed files copy the status of their father. the same applies to 89-92 and 97-98 steps

can you make a donor rawbin backup of an emummc

Envoyé de mon SM-A505W en utilisant Tapatalk
with this guide you can save your sysmmc.
so why bother emummc?
you don't have a nand chip?

if thats the case this is interesting.
if the emummc works without a physical emmc chip then i make a guide for that too later, but i don't have a spare sdcard for that right now.

but if i'm right this guide will help the emummc too because you can mount that too and do the nxnandmanager things on that.
and you can create a emummc partition on the sdcard with tegraexplorer on the partition sdcard tab.

if i have time i upload my donor switch nand backup with the prod.keys file too to 1fichier then we don't need a donor switch, just the nand backup and the prod.keys file.

10. Unmount your sdcards in hekate go to Tools / Backup eMMC do the eMMC BOOT0 & BOOT1 and eMMC RAW GPP too.

11. After the backup finished remount your sdcard and save the backup folder from your dead switch on your pc somewhere.

12. Go into the backup folder and you will see a similar folder to this 5b4d2a82
in that folder there is the rawnand and the boot0/boot1 files. after copying the backup folder to your pc from the dead switch you can delete the contents of that folder.
Hello, thank you for your Guide.
I try to revive my Switch which have a bricked eMMC: “failed init eMMC”. The only backups I have are the prod.keys.
Do I need a backup of my eMMC BOOT0 & BOOT1 and eMMC RAW GPP, because if I try to dump a Backup the process crash’s with the log “failed init eMMC”? So I can’t make any Backup.
Is this required?

if your emmc is fully corrupted don't suffer with the backuping.
you have your switch own prod.keys that is the point.
you need a nand backup of another switch and you need to restore that on your faulty switch.

but first remove your switch backplate and try to plug out the emmc and blow a little air in the connector socket and plug back in your switch.
in the best case you just have some contact issue with the emmc or switch connector socket. (like some strand of hair sorted some pins)
in the worst case you need to replace the emmc chip and do my guide from step 1.
but if i have time i do a guide for emunand without emmc chip and you can able to save it without buying a new emmc chip, you just need a big microsd.

Ok thank you, I firstly will wait for your emuNand Guide and try this method because it sounds much safer then changing the eMMC-Chip.

Nice guide!
I don't think it's actually possible to run emuEMMC without a working eMMC; I tried to explore this route but people here told me that the emulation still relies on some functions from the physical chip so it has to be working. But if you could provide rawnand.bin and its prod.info for decryption that would be great because that's where I'm stuck also D:
I'm following this guide: https://gbatemp.net/threads/guide-nand-rebuilding-for-no-backup-broken-emmc.593995/
It's actually trying to achieve something very similar to you but it also requires a donor switch which I don't have

If your eMMC cannot be seen in Hekate (like you said, "failed init eMMC”), the only thing that can help you is mmcblkNX or something like that: https://github.com/ignasurba/mmcblkNX
I'd emphasize that it's the only thing that might work. I ordered one, waited a month for it to ship, and found that my eMMC was still not readable (did not even recognize device). The next thing to try would have been to reflow/reball but that is beyond my expertise sadly.

If I right understand in some cases a eMMC-Partition can get unwritable. With such a adapter you are able to fix this issue under Ubuntu.
I examine my Switch again and found out, that sometimes I can read BOOT files, but RAWNAND not.
But this is only sometimes the case, often the system logs “failed to init eMMC” also in BOOT file dump.
Can this might fix my case?
