Look README:

Code:

Flash original (non modified) same version bios, then, after reboot,
flash modified one. (run flash.bat as Administrator)

I did try with "WinPlash" and there I got error message "corrupted interface descriptions in new BIOS file" Part table signature not found in the Interface. Error code -161

Here is prt srn.:

I also did try to run original flash from windows but I got message "BIOS image is same as BIOS rom, no update need at time" so I can reboot and run modified one.

You are my last hope. It looks like you've had tremendous success with whitelist removal for everything but a T420. I was hoping you could help. Thank-you!

Thanks!! Will this bios mod allow me to put a 7260HMW 802.11ac WiFi ac in my T420?
