As the title suggests, HPs failure to properly provide support OR updates for such laptops is outstanding, therefore I am reaching out to this wonderful place.
System Model: OMEN by HP Laptop 17t-cm200
(HP official website does not see 17T-CM200 as an actual model prob because it got discontinued, it is recognized as 17T-CK2000)
System SKU: 70W93AV
2 months ago I updated my BIOS from F.11 to F.12 as per update recommendations. A few days later after updating, I was hit with a âBitlocker recoveryâ screen. Unsure what caused it, I entered the recovery key and went on. I have some apps for my Engineering that need TPM Modules to be available most of the time. One of them warned that the TPM Module is missing. I went on the check the BIOS configuration and all seems to be clean and working:
TPM is set: Available
TPM has been: Cleared multiple times
Defaults were applied multiple times
CMOS has been reset multiple times (Win + V + (3 sec power button)
Attempts to downgrade BIOS failed (WIn + B +(3 sec power button) + USB with BIOS files
Clean installation: Windows 11 and Linux Ubuntu to verify that it wasnât some sort of OS issue
HPâs own cloud recovery method
UEFI and Intel CPU diagnostics found no abnormalities.
ME in the BIOS has version: 0.0.0.0 Despite downloading all required drivers
NOTE: This laptop has fTPM module, not a physical one.
At this point I am greatly losing hope of restoring my laptop into itâs OEM bios config. So I am considering either some sort of bypass way to force flash older BIOS firmware (F.11) or get myself a CH341A/CH347 Programmer and just force reflash the entire BIOS chip, hopefully restoring these two pieces.
Peace!

Look like a corrupt ME, indeed. MeatWar gave you the link for the cleaning procedure already. This procedure is described for ME up to version 15, but 16.x will work accordingly.
For the Intel tools search for 16.1r0 in the forum. Try to make a dump with fptw64 -d SPI.bin
Unfortunately anti tampering / recovery features have been introduces widely in these generations notebooks. You should check for redundant information / other large SPI chips when dumping your firmware!
The HP firmware update contains a complete Intel firmware image, so you could simply use the ME region extracted from this update and replace the ME region in your dump.
Your system might have a firmware TPM, so be sure to have secured the recovery information for every encrypted drive!
And again, make sure to check for recovery SPIs which may have duplicate information and to (cautiously) dump it, too.
So I have attempted all that said. I might be doing something wrong since I am always unable to go past all software related to fw update. The issue is that is just cannot detect the ME hardware and it cannot proceed. Is there something I am skipping or just ainât doing right? Is there isnât anything does that actually mean I will end up using the Programmer tool I mentioned in the beginning?
Thatâs very unspecific- âattempted all that saidâ isnât very precise - conclusion is as you said âyouâre might be doing something wrongâ.
Attach the files you created / the dump you made or the commands used and their results- then we might be able to advise.
Sorry for making myself unclear, I was rushing and did not really check out what I was going to send.
I am going to redo all steps and document each step of doing the guides.
So Currently I dumped my SPI, got the file, analyzed that itâs 16.1.32.2418
Okay so now I might be dumbfounded somewhere around the part where the File System State is suppose to be Initialized rather than Configured, is there a way to make Initialized?
I donât understand what you tried to generate with FIT.
But since HP does provide a complete firmware image you can simply use it. Transfer the first and second padding in bios region from your own dump to HPs firmware image.
Be aware that thereâs the second NVRAM volume missing, the system will generate it automatically later. But that means that second padding not just begins after the NVRAM, but 0x40000 âlaterâ, at 0x683000
Do you mind telling me about the SPIs with 16 MB or a little smaller? What other software will allow me to extract more SPIs from the board? Sorry if it sounds somewhat stupid but I am lost abit.
You need to provide motherboard information, detailed hres photos, hp product number etcâŚ
ex: SPS N35247-601⌠many modern systmes have multiple NOR flash ICs and we are not HP employes to have access to all relevant repair information/schematics of all system ww
In short:
I have to get every single information of my motherboard, including the actual text on the Mobo itself? like Disassemble the mobo and take pictures of the chip and the codes it has on it .
You do as you please sirâŚits your task only and the system is in your possessionâŚnot oursâŚ
Didnt you mentioned the possibility of using a CH341 programmer in 1st post? Well⌠this is relevant for operationâŚlike this example:
I am sorry, that sounded somewhat rude. I did not expect this to be an easy work. I played around bioses multiple times, sometimes success sometimes fail. I never did anything around HP bioses. I do know that I can flash the BIOS chip the hardware way. i will post the specs later on.
Does that mean im not expected anymore at âThe Excelsiorâ for dinner and after-hours party with a bunch of twenties girlsâŚall pay by youâŚdamm sir, ill try to be more gently at you and more rude to my womanâŚsome nervs!!!
Get on your âhorseâ do your job done and feal lucky if succededâŚOVER_N_OUTâŚof here.
