I found this thread, here, and have almost the same issue.

The ME Firmware Version on BIOS Main screen is blank.
To boot, I'm forced to press the power button a few dozen times and even then it boots intermittently.
When it does boot, it takes almost a minute to POST but everything seems to be working just fine afterward save refusing to reboot and just shuts down instead.

I have another identical T460 that works just fine and has latest BIOS (v1.42.1.11 R06ET68W) and IME (11.8.70.3626) flashed.

I'm going to purchase this kit.
Can I simply read the working chip and write it to the non working machine?

OK, so I've got the programmer and a clean dump by following section D4. CSME 11 - 12 of the Clean Dumped Intel Engine guide.
I did all of this in Windows and everything seems to check out. (File sizes identical and DATA section is Configured and NOT Initialized.

My issue now is with step 15.

"Last but not least, once your new cleaned+configured SPI/BIOS dump or Engine region is flashed on the target system, run Flash Programming Tool with command fpt -greset and wait for the system to reset (no settings are lost)."

I'm not sure how I go about flashing the cleaned .bin to the chip.

I tried using flashrom in Linux but got an error:

$ sudo flashrom --programmer ch341a_spi -w outimage.bin
flashrom v0.9.9-r1954 on Linux 5.3.0-40-generic (x86_64)
flashrom is free software, get the source code at https://flashrom.org
 
Calibrating delay loop... OK.
Found Winbond flash chip "W25Q128.V" (16384 kB, SPI) on ch341a_spi.
Error: Image size (6303744 B) doesn't match the flash chip's size (16777216 B)!
 

How do I actually flash it with the programmer?
I can use either Windows or Linux if that makes things easier for anyone willing to help me out.

Thanks for the reply.
I flashed the me region only, but the ME Firmware version is still empty and the serial number is still incorrect.
Perhaps I'm not understanding Section D4, step 9 in the Clean ME guide correctly?

I ended up successfully dumping the BIOS from my other T460 20FM model.
That dump is here: https://anonymousfiles.io/yYyAfAif/
(I tried attaching it to the post, but it was too large.

I'm really not sure what I'm doing wrong here. :(

Again, thanks for the reply.

EDIT: just saw that you changed the wording, disregard this:
I'm not quite understanding what that note is wanting me to do exactly. It's worded a bit strangely.
Also I'm not sure how I follow along on a full SPI as the guide seems to always result in a ME Region only file as alluded to in post number two of this thread (the flashrom size mismatch).

The working dump is in my previous post.
Here is the original: https://anonymousfiles.io/kZfcTJTt/

I really appreciate your help. ;)

Unable to flash:

Error 368: Failed to disable write protection for the BIOS space.
FPT operation failed.

Insofar as I know, the second dump I gave you was "proper".
I read it via the CH341A software when I first got it.

Flashing your repaired/cleaned copy via the CH341A software now.
I'll report back after I put it back together and have a look.

Everything seems to be working with your copy.
It still had the incorrect MTM and Serial number and one or two settings seem to be different/missing but I can live with that.
I ended up running the Lenovo Maintenance Disk, https://archive.org/details/i7tm38us, and corrected the MTM and Serial.

Thanks so much for all your help!

Out of curiosity, which image did you choose at step 4?
Maybe I was using the wrong one.

Understood.
I don't know where I went wrong, but I tried both NPDM RGN and YPDM RGN and still failed.
:(

I think I know where I went wrong.
Step 6 in section D4 says:

6. From the System Tools folder, go to Flash Image Tool > WIN subfolder and run fit.exe. Drag & drop the dumped SPI/BIOS image you want to clean. Go to "Build > Build Settings", select "No" at the option to "Generate Intermediate Files", leave all other settings intact and click Close.

But looking at the spoiler image, in the lower left, it appears as though you dragged and dropped the bin file from the repository (the one from step 4 before renaming) instead.
Is this correct?
