@Homeless Ok, lets take the old-school route. First flash the official 20A bios from Gigabyte using EFIFLASH. Then post a new RW report.
@Luciann FYI, the mod is perfect. SLIC Toolkit can't work under UEFI/GPT systems. If you again install Windows in UEFI mode, just insert cert & key. To check SLIC under UEFI, use RW-Everything.
The mod is WORKING and that's the important thing for me. Even if i want to install Windows in UEFI again i can't use it, my onboard sound doesn't work, i get code 10.... installed windows 3 times, install one driver at a time with reboot, tried 3 diferent version of drivers. Regarding the bold (i did that) from your post, SLIC Toolkit works just fine on my main pc with Windows installed in UEFI, see the screens attached. It's that any different than the "bios" resulted from the steps bellow ? (just asking) 1. Start Phoenix tool 2.14, then -> 2. Select your BiOS file to mod 3. Select manufacturer "other" 4. Select your desired SLIC 2.1 file 4b. Select the matching certificate file and press verify (this part is optional) 5. Select method "dynamic option" 6. Press "advanced" to modify settings 7. ticked "insert SLP 10 Module for slp mods" 8. Press "Done" 9. Press "Go"
