I got 2 rx 570 8gb sapphire + the one with lights. So this one comes from mining so i knew that this needed to be flashed with its stock or original bios so i got mine at techpower. i checked first the vbios version all are the same but only the subsystem id is different mine i think has 1DA2 E366 the one i downloaded from techpower was 1DA2 E343. Ya i know it was different but i did this last night from the other rx 570 it just worked fine and was fixed. So what i did to the fixed one, i used the amdvbflash but it comes with subsystemidmismatch so i flash it with command prompt and now it works. So this bricked one i flashed it without saving the bios or backing up the bios that is inside this 570 (the bootable one) so got an subsystemidmismatch so i did what did last night with the command prompt and then restart it immediately. After restart my pc won't boot the fans of gpu, cpu, led fans all working but the lightning in my keyboard wasn't turning on and the monitor showing no signal. So i switched bios ( the switch in the gpu itself ) So it boots now. Then i've done it again with that command prompt now it wont boot again please i badly need help guys!!! and btw i have my main gpu its an gaming x rx 580 so this is what i've been using to post this thread. ANY HELP WOULD BE GREAT!!!!!!!
