alexwarren123 Posted November 16, 2016 Share Posted November 16, 2016 Hi All, I have recently purchased a dell 770m to revive my M17X R3 with a broken 580m inside. I have flashed it to the unlocked A12 Bios, Disabled integrated graphics, set the display mode to PEG, and disabled integrated audio. It could boot with the 770m but it was not detected, so the vbios needed flashing. I tried flashing to a 770m Dell vbios, however the PC will not boot with the GPU in now. Upon doing a blind flash back to the default A12 bios, I can get the laptop to boot without a GPU, but with a GPU it hangs on the red bar on the bios splash screen. I need to know how to blind flash my GPU back to a working BIOS, every attempt using END+power in just seems to reset the default bios, re-enabling iGPU etc. I have a memory stick prepared with a better 770m BIOS along with nvflash and an autoexec.bat file, however I cannot get it to boot as it just hangs on the splash screen with the GPU in. Thanks, AlexTL;DR - GPU has a bad BIOS, how do i re-flash it if it can't boot. Quote Link to comment Share on other sites More sharing options...
