Update BIOS and Unlock Better Performance

English | 中文

Introduction

The BIOS packet in Firmware v0603 folder is from Xiaomi stuff, so it is reliable. It is highly recommended to update to 0603 version because the script for fan fix is based on that version.

The ME firmware in ME folder is from Fernando's Win-RAID Forum. Using the latest ME firmware helps avoiding potential malicious attack. The ME firmware version in the folder is Intel CSME 11.8 Consumer PCH-LP Firmware v11.8.55.3510 and the version of Intel (CS)ME System Tools is Intel CSME System Tools v11 r14 - (2018-08-09).

Warning: Since the operations are related to BIOS, there's possibility that if some errors(such as force quit the update program) occur during the update process(so as to scripts in #8), the whole system may unable to boot.

If unfortunately this situation happens on you, you need to find Xiaomi stuff to fix your device. If you use this program, you should agree that you are the person who take whole responsibility, instead of the author.

How to update BIOS

  1. Download all the files in Firmware v0603 folder.

  2. Extract all the files and copy them to the root directory of a FAT32 U disk.

  3. Restart your laptop and press F12 botton to choose U disk to boot.

  • IMPORTANT: From this step, your computer should keep in charged by AC adapter until the whole update process finishes.

  1. In the new shell interface, type unlockme.nsh and press Enter, then the system will automatically restart.

  2. Repeat the third step, and this time type flash.nsh.

  3. Wait until the update process ends.

How to update ME firmware

  1. Download all the files in ME folder.

  3. Make sure, that your notebook is connected to a charger and in the loading mode.

  4. Run the Windows PowerShell as Admin and type the following:

  1. Now type the following command:
.\FWUpdLcl64.exe -F ME.bin

(note: the first character is a dot!) and hit the Enter key. The rest will be done automaticly.

  1. Wait until the process has been successfully completed.

  2. Restart the notebook.

How to unlock better performance

FallenChromium and Cyb created scripts for changing DVMT size from 32MB to 64MB, unlocking MSR 0xE2, and editing Embedded Controller(EC) firmware to reduce fan nosie. For more information, you can visit #8 and cybsuai's repository.
