You need a separate PC to do this. The following steps are extracted from Zelgar post Here, a very good summary indeed. You need a fully-charged X98.
I’ve followed that guide and as I said in my original post it requires you to boot to Android and enable debugging mode.
I only have Win10 on my tablet so the flash.bat doesn’t detect the tablet and fails.
Surely there must be a way to flash the bios directly from Windows on the tablet itelf??
