Ok so..i guess i can't brick it.
So if i flash a corrupt BIOS i can re-flash the correct one again? Then that's what i wanna do.
Yes it's for RMA...i know in usa or eu they can easily find out.... but in our country it doesn't work like that...you just send the gpu to the shop and if they can't run it they let you take a new one immediately and send it for RMA later themselves lmao . so what i basically want to do is make the gpu unusable for a while, but not permanently damaged so that i can recover anytime.
