Hello I also just did the same incorrect thing. I flashed back to 1.12.0 and then thought I could recovery flash to 1.3.2 and Alienware Area51m R1 will not boot. I now see that I am up against issues where the flash back to 1.3.2 would never succeed due to Intel ME firmware (dang).

Can I somehow use these posted BIOS files to recover to 1.7.3? I would like to preserve my Service tag and Windows key if possible. Thanks if can share the edit offset.

I need to hex edit the BIOS file and then desolder the BIOS SPI chip and flash and replace on mobo.

My service...
