Need help with Thinkpad x131e Bios Flashing!

[tutin2678]

Hi, I bought a x131e second hand laptop which has windows 10 enterprise 64-bit installed. I tried to flash the latest bios: https://download.lenovo.com/pccbbs/mobiles/g8uj23us.exe but it failed to do so with the error 235 - Oem check failed.

I've tried to use the boot iso they got on their site too: https://download.lenovo.com/ibmdl/pub/pc...uj23us.iso but it also failed to flash.

I believe the BIOS is Phoenix BIOS. Can you guys help me find a way to flash this?

I've tried winflash64 (phoenix uefi flash tool) but the files are in FL1 format.
