Thank you so much for continuing to assist me.

Tl;dr: The very first bin file you sent worked!

I flashed back to the original saved bin and it didn't work until I realized the write wasn't working. I erased the IC and was able to flash to original bin onto it and it worked. After doing that I erased the IC again and put the very first bin you sent in response and it worked like a charm. Apologies for not investigating this more before asking for help.

Thank you for generating another BIOS. I flashed the BIOS with it and just like the previous one, the computer doesn't POST with that bin....

Thank you for the response! I really appreciate it! Sadly, I've tried flashing that bin to the computer and it refused to boot. Afterwards, I flashed back the old bin and it started up with the password as before. In addition, I've also tried following some tutorials and downloaded a clean CSME 14.1, placed it into the region and regenerated the image. The resulting image also didn't remove the BIOS password. If at all possible, could you take another look?...

I managed to download the BIOS. Can somebody help me remove the admin password? Many thanks in advance!...

Hello everyone,

Decided to join because there were a number of articles that I cam across when attempting to flash a BIOS and bought a CH431 to learn more about firmware and hardware in general. Appreciate all of the help that people are providing...

Hello,

I am have a similar problem. I have HP ProDesk 400 G6 DM.

Serial Number: MXL2083TCW
Product Number: 9AG51AV

The BIOS is locked and I would like to update it. I've bought a CH431A programmer, a 16pin clip and IC clamps. Using Netprogrammer and AS programmer, I cannot get the chip to read out. I've tried a number of things but including using the IC clamps rather than the clip. I have a number of questions, if anybody has a few moments I could use the help and would greatly appreciate any advice.
