Hello. I have the tbook16power (M5F8) too. I wiped the internal Memory and flashed it new with intel phone flashtool (only Android). Then i booted a windows 10 64bit uefi installation-Stick and installed windows. All works fine. Then i flashed android TWRP-Recovery for teclast tbook 16 power (m5f6?) and it works fine too. then i rooted theandroid and it works two days verry fine with android and windows. but now, the Battery goes empty becouse of forgotten to charge. and after charging, the white Bootmenu was lost. at first, i could switch with “Boot to Windows” or boot to android-Apps, but since today, all switching is lost…
Does anyone knows how to get the Bios or EFI Files? I think, the Bootloader or Bootmenü is stored in the BIOS, or EFI, or at some other places,not in the emmc.
