Sorry... Thanks for the feedback. /Strange... the same method's mod was used for MSI B360M PRO-VH mobo with success
I have a CH341 SPI programmer and I tried to flash nonmodified bios from MSI site using it, but the mobo gave several long beeps and switched off. And doesn't start. Have you any suggestions how can I recover it now? Probably You can make another mod? In successful mod above slic 2.4 was used. Update: I have now revived the mobo by flashing previous original bios (A4) using ch341 programmer. Flashed it to latest original (A6) bios again using built-in M-Flash with success.
