Dear plutomaniac,

I have cleaned more than 100 images with the help of your efforts, but there is one image I have a problem with. When I open it with FIT and I have 4 files: Bios Region, ME Region, etc.. The extracted ME region from this image is 1MB smaller than the same image from your repositories and I cannot build a new image with it, the FIT program crashes (End Task). Can you please investigate where is the problem?

The image is from HP Elitebook 840 G2 notebook.

I am interested in one more thing. I head that DELL is giving a customers option to choose whether to have ME in bios or not. Its like they can remove ME completely from bios if customer asks for it. Do you know if this is possible and can you remove it?

Hi @plutomaniac

May I ask for your advice? I got few dumps of bioses for my laptop model (Dell XPS 9550) from different sources, and I'm trying to go through cleanup process. But my issues is - neither I use my original dump (made with programmer) or any of other dumps from other machines - FIT doesn't open them crashing with error. There is "identical" model Dell Precision 5510 that has mainly same hardware, same version of BIOS and same version of ME firmware - and i can open it's dump image with FIT - but i'm little bit scared to write ME based on non-native BIOS (for next few weeks I have no access to programmer, but i can unlock flash descriptor)
Here are dump - https://drive.google.com/open?id=1HpZeBs...91O6ZEwjg180bdh

@plutomaniac

I'm not sure about two of this dumps. But at least one is from trusted source (that one that have long name "Dell XPS 15 9550 - Compal AAM00 LA-C361P - Rev 1.0 (A00) UH8.bin" - it was made by one enthusiast from working unit). Also, my own dump (it's not in that archive) - has Corporate H. And has same issue loading into FIT. How it can be? How Dell is making this images if even official Intel tool is rejecting to load this images? Do you have any idea what may be issue and what may be workarounds?
Also, what if i will take operational ME image from other same laptop (but much older version of ME - some of initial versions when laptop was released) - and will flash it on my laptop without cleaning ME data? My laptop has strict Boot Guard enabled, so if i will screw up ME - most probably only way to recover laptop will be to reach my programmer.

@plutomaniac

This is my own dump:

This is dump from similar model (actually, only difference from my model is discrete GPU - i have Geforce, and Precision has Quattro)

Also, I forgot to write that my main issue - ME stuck on BringUp phase with "CHECK_BUP_OVERRIDE_STRAP" status

P.S. I did just check BIOS update packages for both XPS 9550 and Precision 5510 - they are absolutely same. Do you think this means that i can take ME configuration from Precision to prepare ME image for my laptop (following CleanUp guide)?

@plutomaniac

Thank you very much! Just got my programmer, flashed that image, and now things are looking much better - at least i have now my ME interface device back, and meinfo is giving response with a lot of information. Will test a little bit more, but for now looks fine

Hi,
I was reading and following the guides and very useful for me with learning and playing around. I got stuck with the current device with mixed up firmware that I cannot understand how to work on it. I spent a lot of time trying to understand but the machine partially booted with glitches or sometime no boot at all.
Can you please help with the clean ME for the machine and explain a little on what version tool used, how it works? It is embarrassing that I cannot do it after you guys spent so much time to detail the process. The file is extract from another machine.
Thank you for your help.
