There is some alternative better software you can use with the CH341A .NeoProgrammer ,AsProgrammer ,Colibri .You`ll find them all on the forum if you search. Always make 2 backups and verify they are both the same using a hex editors file compare function . HxD - https://mh-nexus.de/en/hxd/ .

Post your original bios backup.
