For those who have an X1 extreme with the problems of:

-Long reboot start…

-Message (A7) ME FE Downgrade - Request MeSpiLocK when starting after the LENOVO logo.

-ME Firmware version white in the bios

-It did not work the sound of the equipment.

…And the solution "Re: P52 4K, reboot three times forever, after Intel Update 12.0 Firmware. Via Lenovo Vantage" given on page 7, did not work for them:

You can try the solution THAT WORKED TO ME and that I explain on page 2 of the thread "Re: X1 Extreme" (A7) Me Fw Downgrade Request MeSpiLock Failed " and that I copy below:

Instructions:

Note: the quotes “ ” are not written

Attention: the corporate version "ME_12.0_Corp.bin" is the one that I used in my ThinkPad X1 extreme with i7-8850H vPro

1. Open command prompt as admin,

2. Write   “cd..”   and press enter.

3. Write   “cd..”   and press enter.

The objective is to go back on the route until you reach

C: \>

4. Write  “cd drivers”     and press enter.

5. Write  “cd win”           and press enter.

6. Write  “cd me”           and press enter.

The goal is to get to the route

C: \ drivers \ win \ me>

where the files that installed the failed firmware update should be.

7. Copy the following line by selecting it and copying it with "Ctrl+C"

FWUpdLcl64.exe -F ME_12.0_Corp.bin -OEMID 4C656E6F-766F-0000-0000-000000000000 -allowsv -y

8. Paste the previous line with "Ctrl+V" in the line of the command prompt

It must be

C: \ drivers \ win \ me> FWUpdLcl64.exe -F ME_12.0_Corp.bin -OEMID 4C656E6F-766F-0000-0000-000000000000 -allowsv -y

9. Press enter and follow the instructions.

10. If everything went well it will rewrite the firmware (eye the corporate version is the one that I used in my ThinkPad X1 extreme with i7-8850H vPro "ME_12.0_Corp.bin"), the writing percentage goes out until it finishes and asks for a restart

11. Restart

12. Good luck!

For all those who are angry against Lenovo for these problems. I must admit that even if Lenovo replaced my motherboard 3 times under warranty to resolve my P52 problems. It was with professional quality of service and my system work very well right now.

Hello, I also have the problem mentioned here. Meanwhile, the 4th motherboard is installed. Every time I update Intel ME, the version number disappears in the BIOS and the computer takes a long time to boot. Any ideas?
