Fix update 14.0.0+ error
If you followed one of the guides like this one chances are you will get a 2105-0584 error crash when you update to any firmware above and including 14.0.0, despite updating atmosphere/sigpatches.
If so, go to https://github.com/CaramelDunes/prodinfo_gen and grab the latest version of prodinfo_gen.bin.
Use hekate to place the donor_nand.bin from the guides into the /switch folder, and use RCM to inject prodinfo_gen.bin.
Follow the on screen instructions to create a PRODINFO using a donor nand (not from scratch!)
Go back to hekate and copy the generated_prodinfo_from_donor.bin file onto your computer.
Use hekate to load the eMMC that is having problems, with read-only protection OFF.
Use NxNandManager to load the drive, and click on PRODINFO (not the one with f at the end) and select restore from file.
Pick the generated_prodinfo_from_donor.bin and let it restore, this should only take a second.
Once you're done try to launch CFW again, it should work now.
