Hello Guys, my first time here, i hope you can help me with this one last friday i bought a Sapphire Pulse Vega 56, ( 3 display ports and 1 HDMI ) In order to obtain vega64 performance and unlock higher voltages in samsung HBM, i flashed the Sapphire Nitro+ Vega64 bios. Everything ok, the card boot up nice and smooth. The problem is, the Sapphire Nitro+ card has 2 display ports and 2 HDMI, so i noticed that my 3rd Display port is dead with this bios ( wich makes sense ). So i tried to flash back the stock bios ( i've made a backup with gpu-z ) and problems starts here. i repeat the same procedure, CMD in admin mode // atiflash.exe -unlockrom 0 // atiflash.exe -p 0 -f bios.rom, atiflash gives me following error: ( write passed 80000/8000, write verified 2/80000 fail, error 01FL1 ) If i try to flash the VEGA 64 NITRO+ again it flash's without problems, but i've tried almost every bios from techpower gpu database and i allways get the same error. i tried boot with the rescue bios and switch to the first one, but same thing happens! Tried another computer, same thing. It seems to me that must be some kind of downgrade protection because its the only bios compiled in 2018 in techpower database! i think i allready tried almost everything!
