What you'll want to do is flash back your rx580 to either its original vbios or the right one you were trying to flash.
If you have not saved a copy of the original vbios you can find it on techpowerup's vga bios collection

i call msi rma and asked them getting original bios is possible and they send original rx580 bios. Then i purchased eeprom flash device(CH341A if anyone curious) for external bios firmware correction. And i manage to get my rx580 back in bussiness.
