Homebrew How to restore serial number with atmosphere back up

[Superkidxl2099]

I was currently wondering how to restore my prod keys after I had messed up with incognito rcm, I know I’m not banned because my servers aren’t restricted by Nintendo and my serial code is xaw0000. I had read up on a possible method of restoring the switch with atmosphere back ups which I luckily had saved due to me downloading a game for my ps3 and backing up all my switch files. I just wanna know how do I use my original prod keys that are xaw9(etc) and restore it back to the original serial number

My prodkeys on my sd card are xaw000 but the ones on my pc are the originals

If you used incognito_RCM, do you still have the resulting prodinfo_sysnand.bin or prodinfo_emunand.bin? If you do it's as easy as putting them back on the sd card root, booting Incognito_RCM and clicking restore.

If not and you have a sysNAND or emuMMC backup, you can try backup your current NAND to preserve the data, to restore the old backup, use Incognito RCM to backup the keys out of it, restore the new backup you did and restore the keys from Incognito RCM.
