Hi, Ihave the FPC connector of SD reader broken, and I need the prod.keys for injecting saves on Sysnand. Is there a some CFW that save my prod.keys on USB, print on Screen or on EMMC? Or any windows app that extract this file from Switch?... Thank you ...

I do remember there was payload, that shows qr with keys on screen
Good memory. Are you talking about biskeydump or sa different one for prod.keys?

https://hackinformer.com/2018/04/30...-windows-thanks-to-tegrarcmsmash-by-rajkosto/

Now as a test-payload we will use biskeydump.bin which will dump your Switch’s device key. DO NOT under any circumstances share this key online. Download biskeydump.bin from here (Just extract the zip file to get the .bin file). Copy the bin file next to TegraRcmSmash.exe. Now just drag and drop the biskeydump.bin file onto TegraRcmSmash.exe and see the magic happen on your Switch. To ease getting the keys and not having to manually write them on your PC the Screen shows a QR-Code. Just scan the QR-Code with your Phone and save the text generated from it in a Test file.

You need a Micro SD card for anything CFW related, so before continuing, just get one!
If you don't have a Micro SD adapter for your PC, you can just use Hekate to move things to/from the SD card over USB.

Oh, god! Just realized the SD slot on OP's switch is broken. Shit

SD READER CONNECTOR is the easiest connector to replace in NS IMO.
Yes, even easier than 4pin backlight or fan connector because they are made by MOLEX and the plastic doesn't melt even you hot air the new one on the board.

Can someone list all the keys from prod.keys that are hardware specific?
My son is out w/ my other Switch. As soon as he gets back I will diff my two prod.keys and delete keys that match.

If someone else already knows, please chime in.

tsec_key = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
secure_boot_key = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
sd_seed = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

# These keys can be derived from tsec_key and secure_boot_key
device_key = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
bis_key_00 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
bis_key_01 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
bis_key_02 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
bis_key_03 = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

These are the unique if I remember right.
Also some googling
