I can send my hex edited and unlocked ones but thes still show 640shaders So I am still there, it is working but still 640shaders. I had to desolder the bios flash spi ic and made an Arduino SPI flasher circuit and flashed back original with it and soldered back to make it boot and work again. No computer was booting up with it even if I set onboard graphich to default, preferred, so could not flash it back from PC. I also made a desperate attempt flashing a Sapphire RX550 unlocked bios, but as winatiflash does not alow it in win due to dirrerent subsystem ids so I manually efited in polaris the ids same ad yeston ones, but did not change offset.
I tried to unlock shaders with SRBpolaris, and also with hex editor same pattern as here, but no matter what I do it still shows 640 shaders only (after restart) in gpu-Z.
