Failed to match warmboot with fuses (HELP)

[chaDLord]

Hey i updated my STOCK OFW to 20.0.1 but i kept my emuMMC to 19.0.1, when i launch it i get the error failed to match warmboot with fuses. and when i launch CFW - sysMMC i get " unknown pkg1 version" here are some photo (i'm on a v2 mariko switch btw with a mod chip)

When you updated the OFW to v20, it burned the fuses to match v20.
In order to do a warm boot, you also need to update the CFW to v20 and preferably Hekate/Atmopshere as well.
That 'PKG' error is something you get when versions as too old.
