Hello, yes, I started by reflashing the file you sent me, "clearing Keys" in TPM security settings menu, and disabling absolute. I wiped the drive, and tried to reload windows, and same thing. So I flashed the file you sent me again and and tried restoring all settings in BIOS to factory default, and same thing. Still hitting Entra.
Maybe I should load it offline and use the powershell command to see if it's still pulling a key from UEFI?...

Thanks for your effort however, the device is still re-affiliating with Entra. And this is with a totally random clean Hard disk. I must be missing something fundamental here....Leave a comment:

I have a couple of this model laptop that I've tried removing MDM from in our shop standard method here, but these devices are still re-affiliating with Entra. I've attached the original BIOS as well as my attempt at removing if someone could help me out. I can't just do the thing offline because these devices are for further downstream users.

Just got back around to this one today and your file worked. Big thanks!...Leave a comment:

Yeah, I'm afraid so. What's the least bad way to get the device going again. I have plenty of spare chips that will work, but no file. Is there some kind of a "best practices" guide to building an image from scratch with no good dump? I haven't had any success in getting a file from a dell bios update. sadly...Leave a comment:

I think my employee that pulled this chip might have smoked it. The device was not 8FC8 locked, but windows entra MDM. I can't find anything to remove in hexedit and tbh the file does not look normal. After successfully reinstalling the chip the laptop no longer boots. Is this dump garbage? Full disclosure: this is the first Xeon bios that I've dumped so It may just be completely different. Is there a super generic image available? Up thread there are some semi-clean files, but they might have licensing issues I think.

Hopefully I'm necroing the correct thread.
I thought that we were good to go on removing the MDM from these devices, but even after my edit, the device came back with a log in to "customer site" during windows installation. Is there a second chip or somewhere else that I need to edit to fix these? I've attached the original and my "unlock" which didn't actually remove the MDM. I'd appreciate some help on this one.

Thank you! this worked and I see where I was making a mistake. I've watched hours of youtube on this. It took my way too long to figure out removal of MDM lock but I'm 100% on it now. Knowing what to search for is half the battle sometimes. hah....Leave a comment:

Hello, I have a 7410 S/T F6DBC93-8FC8 motherboard is model LA-J261P. I've been trying to learn how to do these unlocks because I work at a refurbisher and although I can get this one into manufacturing mode, etc. The password is coming back after exiting manufacturing mode. On several other laptops I've been able to successfully remove 8FC8 locks so I'm not really sure what I'm doing wrong here. Attached is my original UC5 dump if someone could help me unlock it maybe I'll learn....Leave a comment:

Is this still the case with this CSE ME version?. I've just re-downloaded the repository of ME stuff and I don't see that version in there. Additionally ME Analyzer is not detecting engine firmware in my dump.
Not going to lie, I've been plodding my way through hacking together bios' that work in the 100s of laptops that I need to fix. But my smoothbrain is definitely approaching it's limit... Most of the laptops I'm encountering are not passworded, although some are, the main issue that I have been fighting are in devices that have not been properly retired from an Entra Tenant...Leave a comment:
