I’m using Acer Nitro 5 AN515-54. Everything is good, except no Intel MEI in device manager, no audio (Realtek ALC255 audio codec not detected), Intel ME in BIOS shows
“failed with version 0.0.0”.
No asserting HDA_SDO HIGH.

Already cleaned ME and flash back by CH341 programmer but the problem still persists.
Dumped new SPI image by “fptw64 -d spi.bin” and check ME Analyzer, File System State always shows “Configured”.
Can someone help me with that?
Someone attempted E1. HDA_SDO/GPIO33 (a.k.a. “Pinmod”) and has done damage to the system.
EDIT: If you cleaned it, then it’s re-initialized. If you have any doubts that ME seetings were messed up, search for a donor working dump and exchange ME_region.
You dont specify if this is your system or a user/client repair system… and we here are not “wizzards” to know what the system has been subjected to.
Here’s an image

and an EC

That’s it from me, good luck.

Thank you for your reply . I’ve never tried “pinmod” before.
Can you please analyze this original SPI image?

Your image reports “Initialized”…
In a successful “cleaned” image it should report “Configured”… as the image i linked.
So, you done it wrong…

The SPI image I provided is the original image, which I have not yet cleaned. Here is a clean image:

Pretty much like this to resume…

This is my system; recently, the NCP81215 chip failed, and the machine powered up but displayed a blank screen. I replaced the new NCP81215.
I have just swapped my ME region with a donor working dump and flashed it. The issue persists.
EDIT: I believe the ME hardware does not initialize the firmware.
“pinmod” is the only way to disable ME hardware, but I didn’t do it.
New clue: HDA_SDO is HIGH on the rising edge of PCH_PWR, but then drops back down.
Not seeing a relation with bios or ME fw corruption or even a cleaned one…
EDIT: There’s your issue…
Could you please move my post to the relevant section?
