Hi,

After a bios update from the official lenovo website the pc never turned back on.

I've attached the bios backup that I've taken after the failed update with a CH341a. ( 3,3v mod )

Already flashed and verified, turns on for about 4-5 seconds and then it turns back off. Before that it would only turn on for 2 seconds max.

CSME 11 - 15 & CSTXE 3 - 4​

In this section we have taken as an example a SPI/BIOS image dump of a model which comes with CSME firmware version 11.0.x.xxxx and SKU Consumer H. However, the same applies to all CSME 11 - 15 and CSTXE 3 - 4 firmware.
From https://www.repairlap.com/forums/tools-computer-repair.6/ threads, you will found the correct System Tool and the Me Region and TXE Region needed.


1. Open the dumped SPI/BIOS image with ME Analyzer to see what major/minor version we need as well as SKU. In this case we have:

I've opened your files from the archive and they are still "Configured", which files do I need to use to clean the ME region?

I also have error "Unable to open file" in the Intel Flash Image Tool

Just what I did upload above, bought of them 8MB & 16MB

Your file appears as "Configured", the guide says that it needs to be "Initialized", also, despite everything, I still can't open any file in the Intel Flash Image Tool, i says "Unable to open file" and "Reverting to default configuration."

Did you understand what I did send above, you should use bought Bios one for Spi of 8mb and the other one for Spi 16mb .

I know, that's what I did, and it doesn't work...

Should I try to flash them again?

If you need to open the bios files with FIT they must be merged first 8+16= 24mb than use the tool to clean by your self .
Note : not every laptop or desktop with two Bios need to be merged .
