M18x r2 no post after bios modifications

[Gewily]

Hello I have the same problem with my m18x r2 that happened to many before . and as I just bought bough the device two days ago and it's my first time using alienware device I had problem running it with gtx 1070 and I changed few settings in bios that made the device dead to me . starting for few seconds then shutdown . blindflashing never worked I tried many times . so I have to go with your method with the dumb for SPI Rom chip . will appreciate if anyone has the dumb that I can use to fix this . or if there is any other solution to this

Blindsflash should work fine in most cases. Did you blind flash the A03 version without any GPU in the slot? No other version will work. I changed setting for the iGPU once and bricked mine.
