[Problem] Bricked ASUS ROG GL702VM BIOS after WU

Seems this is an old issue you have… on Badcaps.

Rebuild a 310 file with 2nd pad transferred from your dump.
The Asus files are only Bios region so it needs to add to top of it, the dumped 0x220000 (2175Kb).
As an option, you may also clean the CSME fw engine and/or replace with factory empty NVRam volume.
As advised already in BC, i wouldn’t touch the EC as the system responds to PSW, Leds and charge.

We don’t even know if they are indeed your original dump or web collected…so take it as you want.
That’s it, nothing more to add. You may wait for others users POV.
