i am running windows 10 1903, tried to flash by running Biosupdate as admin. I still get the " not valid " error. There is a setting in A15 bios with " Signed firmware update " title which is set to disable and i don't remember if i ever enabled it. It says " This feature when enabled will enforce the verification of the digital signatures in the firmware update payload prior to performin an update of the firmware. Once enable, the system bios cant be updated to any revision that DOES NOT contain a valid digital signature. Note : You will not be able to change the setting once the feature is enabled."
I am going to install win7 and flash it. Let you know. Thank you for the support. Really appriciated Serg ! edit : win 7 same error edit 2 : found this. https://forums.mydigitallife.net/th...mod-requests-section.7500/page-34#post-127010 would it flash this way ?
i don't know what happened with your bios - modified A15 bios was confirmed as working many times...try downgrade to the official A14 bios, and then flash modified A15 bios
