wmedia, I don’t know the version, but found it in the dump on 2015/01/09 10:43:46 (most likely this is Build Date and time), I didn’t check the performance, I just saved the dump from that message from ugabugaLV because it’s rare. Firmware using the i7 Stylus as an example (I think yours will suit as well).
Disable BIOS write protection (Chipset ->PCH-IO Configuration ->Bios Security Configuration ->BIOS Lock ->Disabled), download the program fptw.exe. To backup:
To flash:
After loading, I advise you to make a second backup and compare it with what it was flashed (the hash amount), it should correspond, otherwise, after rebooting, Windows will not boot and you will need a programmer.
