I have a motherboard Asus strix Z490- g Gaming wifi and a 10th gen CPU. I have update BIOS to 2701 version but then I realized that I needed to update the ME firmware first. I didn't read the ASUS notice that said, "Before BIOS update, please download Intel ME update tool from ASUS support site. I updated the BIOS without doing this, and everything seemed fine until the system performed an Intel ME update and shut down permanently. Now the motherboard have "No power issue" and it seems dead!!! My attempts to reflash it were unsuccessful. Searching online, I found several people who had the same issue, and some of them resolved it with a ch341a. Does anyone have the proper ME firmware so I can reflash it on 8mb chip?

You can't just reflash only the ME into the bios with ch341. Ch341 can't write part of the spi chip, only the whole image. What you need to do is: 1. Backup current bios image from the spi chip to disk, 2. Download a stock bios image from Asus site which has inside a next lower ME version included, this will be in a lower bios version, but not necessarily in the first lower bios version, 3. Extract the ME from this stock bios, 4. Exchange the ME in the bios image you backuped from the spi chip, 5. Program this image with exchanged ME back to the spi chip, 6. Repeat steps 2-5 with next lower version ME's until you get a match between the ME version in the bios and the version the chipset expects and accepts.
This process is the only way to preserve the DMI data and MAC address in the bios, which is unique for each motherboard. If you just program a stock bios image to the spi chip you will loose this DMI data for ever, eg. having no valid MAC address, no UUID, no serial no, etc.
For viewing / editing bios image you can use UEFI Tool and UEFI Tool NE or any other tool which allows to make such operations. This is somewhat demanding, but there are good instruction how to do this to be found in the internet or just ask AI.
You can also find all possible ME versions on station-drivers site, but the issue with ASUS is that their ME's are usually not standard Intel provided ME. ASUS does often customize their ME's, so stock Intel ME's not always work fully, eg. some M.2 ports not working, or other weird issues. That's why is is better to extract the ME from a stock ASUS bios image or alternatively from the ME update software packages provided on ASUS support site.
If all this does not work due to ME mismatch between bios and chipset you will probably have to program the first stock bios version to the spi chip, having before or after transferred the DMI data and MAC from the backup BIOS image to the first stock bios image. The first BIOS version on ASUS boards has often the ability to reinitialise the chipset on the first run to accept a new ME (a factory initialisation process). There are also Intel CSME tools which can modify any bios image to do this, but this is a process demanding lot of advanced technical knowledge, not easy to do due to lack of any publicly available instructions. Make sure you have a proper CPU supported by this first bios version.Last edited by DynaxSC; 03-25-2026, 06:49 PM. -
Thank you for reply. 2 questions:
1) I have uefi tool but how do I extract the ME from this stock bios?
2)Are you sure second BIOS chip (8mb) has only ME firmware on it?Comment

Why isn't the Asus BIOS-FlashBack (low-level switch) function working?Comment
-
Hello! Led is steady and when I press the flash button, led flashes one time and becomes steady again. I have used many USB sticks with many BIOS files with NO result. I don't understand the reason....Comment
-
I am using 8gb flash-drive with normal partitioning and FAT32 formatted.
The file has been downloaded from https://rog.asus.com/motherboards/ro...helpdesk_bios/
and has been renamed using BIOSRenamer. Some people say ME firmware of the current chip (8MB) may be corrupted and as a result motherboard reject flashing original BIOS. I have never face such a problem in the past....Comment
-
Sounds appropriate. I suggest you step-back, and then try again ...
Because (like the similar MSI tech on my Intel-i9 desktops) it's designed to work in circumstance of Emergency Recovery like this. If fact, that's ALL it was designed and implemented for (not really even for normal BIOS-Firmware updates).
As an aside ... when MSI, Asus/ASrock makes motherboards for Dell, Alienware, or HP ... they DO-NOT include this functionality. It's reserved only for their real (full featured) "retail" boards.Comment

Did you read tbout that at the win-raid forum https://winraid.level1techs.com/t/so...lashback/37997
Buy a CH341A and a clip and post your backups
Comment
-
I already have CH341A for programming. I just dont understand the procedure so I can prepare the proper files to flash (16mb chip and 8mb chip).....Comment
-
The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..
you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHowIf you have found our forum useful please consider supporting us. Subscribe for a small monthly fee and receive extra benefits including our boardview / schematic archive.

I have already flash with programmer main BIOS (16mb) version 2701 after I have remove header. The problem is that I dont know if the Me BIOS firmware from it is the correct one with the secondary BIOS chip (8MB) which has this file on it. Furthermore I dont know why some people clean main BIOS file (dump) and then flash it again...Comment
-
Descriptor + ME region is on the 8MB chip, it can be extracted from the ASUS .cap, it's hidden compressed inside another compressed section of the BIOS region...
The extracted .cap goes to the 16MB chip, best to transfer DMI from the original backup before blindly flashing anything
Make a backup of the 8MB chip, and try this file (extracted from BIOS 2601), ME version 14.1.51.1528
Also upload your backup of the 16MB chip before you flashed 2701 with the CH341A (you should have made a backup before flashing it)Comment
-
Thank you very much. I will try to flash that one in 8mb SPI chip. I have upload the BIOS files (both dumps and the stock one I have already flashed at Main SPI chip).Comment

I think that 2701 stock BIOS needs Version 14.1.53.1649V1.1
“Before BIOS update, please download Intel ME update tool from ASUS support site, and update ME firmware to Version 14.1.53.1649V1.1 to ensure optimized system settings.”
Are you sure ME version 14.1.51.1528 is ok for 2701 main BIOS???
And why are there so many errors at this file (extracted from BIOS 2601)???

I’m troubleshooting an ASUS ROG Strix B660-I Gaming WiFi motherboard and I’m a bit stuck at the BIOS level. What I’ve tried so far- Attempted to flash the BIOS using the USB BIOS FlashBack (Q-Flash) port with a properly formatted FAT32 USB drive.
- BIOS file downloaded directly from the official ASUS support page.
- Followed the exact FlashBack procedure (correct port, renamed file, standby power only).
Issue:
The FlashBack LED does not blink at all — no activity whatsoever. Further investigation
Because FlashBack didn’t work, I:- Removed the BIOS SPI IC from

Hi!
Went dumpster-diving and found a bricked Lenovo P14S in trash, few weeks earlier. Symptoms - no screen, no POST, no beep, just keyboard LEDs flashing on powerup. Mute button+LED was responding though, and the display self-test was still working (via the key combo Ctrl+Fn+Power held for some seconds, see the Service manual).
Incidentally, Windows 11 have recently started auto-flashing computer BIOS in our region. Even more suspiciously, Lenovo has released a BIOS update just few days before the PC was trashed. About a week later, the BIOS update image has been oficially marked...04-14-2025, 01:56 PM -
With ASUS, not everything is quite so simple. I will show you my way. It may be longer or harder but it is the right way to do it in my humble opinion.
For example, you can have 3 similar ASUS motherboards, all being the same model, all of which will have different BIOS versions.
I will give you an example and my version of preparing BIOS from ASUS website and in the process I am always cleaning Intel ME while doing it so you have fully cleaned BIOS, no DMI data, no password, nothing.
