RCM Replace eMMC (Nintendo Switch)
TODO: FINISH THIS GUIDE :P
If you have a totally corrupt eMMC or want to replace it or re-make an eMMC for whatever reason, you can. All you need to do is have a complete eMMC backup of a working Switch, and the production keys extracted from the target Switch.
You will require to inject the Hekate payload via RCM or similar method.
Firstly make sure you have:
- The prod.keys from the Backup Prod Keys step in the RCM Backup eMMC page, from the target Switch you wish to re-make an eMMC for.
- A full eMMC BOOT0 & BOOT1 and eMMC RAW GPP backup from a working Switch.
Basically, copy the contents of the working Switch backup/[some id] to a subfolder backup/[some id]/restore
Now insert this SD card into your target Switch, inject Hekate, then go to Tools > Restore eMMC to restore the working Switch eMMC data to the consoles eMMC.
Back in the Hekate menu, select Tools > USB Tools
Ensure Readonly to OFF

Click eMMC RAW GPP (sysNAND) and then open NxNandManager, select File > Open Drive then eMMC GPP hekate (double click it).

Then select Options > Configure keyset > Import keys from file and select the prod.keys file backed up from the target Switch.

Press Save. You will notice it will say Bad Crypto and Keyset Needed, this is normal.
... I will finish this guide when I get time. Many more steps yet.
