Cal0 is corrupted, no DK and SBK

Friends, this is my first post, I have a question about a Switch device

I want to know if it is possible to repair a nintendo switch with some missing keys (attached photo)

I have seen some tutorials on the internet to be able to rebuild some memory sectors, but I don't know if it is possible for my case



I don't have the backup of the console, so I got it with that error

Google traductor, sorry iam mexican

Someone probably did a NAND restore with the wrong backup or wiped the PRODINFO data with FFFFFFF
Prodinfo contains some keys and certificates signed by Nintendo.
ProdInfo is stored in the emmc/NAND memory.
Without prodinfo you cannot connect to any of the Nintendo services/update servers, not even with Atmopshere.
If there is an SD card in the Switch, check if there is maybe a backup (prodinfo.bin in the root of the SD card).

If you don't have the prodinfo back, then all that remains is to become a pirate as CFW does not check if the prodinfo is valid.
Older Atmosphere versions did not care about the prodinfo.
Newer versions do care about it and it cannot be blank or corrupted.
If you are still running an old firmware then try out an old version of Atmosphere (see Github)

If you are not able to boot into Atmopshere, I think the following video explains how to rebuild the NAND with a donor image.
