Lenovo Thinkpad T480 WWAN issue and Intel Boot Guard #49

Closed skullface101 closed 3 months ago

skullface101 commented 3 months ago

I successfully patched the Bios However... 1-I cannot remove Intel ME completely due to Intel Boot Guard as it beeps 5 times in a loop 2-The WWAN whitelist removal inst working or is partially working, when i plugged in the Dell EM7455 its not recognized and i cant flash it with generic firmware.

Please help me with the WWAN patch that works properly and help me disable Intel Boot Guard. Note: TPM is working in MFG mode and i need it for windows 11...etc

Bootguard has nothing to do with iME modification. You cannot completely remove iME on a 300 series chipset.

2-The WWAN whitelist removal inst working or is partially working, when i plugged in the Dell EM7455 its not recognized and i cant flash it with generic firmware.

EM7455 is a USB card. T480 does not support this in hardware.

Note: TPM is working in MFG mode and i need it for windows 11...etc

As is stated in the readme, TPM off on this model.

Do some research before blindly buying parts and messing with firmware.

No Em7455 is the same card found in T460 and T470 and i have Unlocked Lenovo branded EM7455 that works even without patching the BIOS I hide the card during boot so it bypasses the whitelist But in order to unlock another card like the DELL one i need to be able to read it first under linux then run daniel's script https://github.com/danielewood/sierra-wireless-modems/blob/master/autoflash-7455.sh

Reopen it

Yes, these models support USB WWAN, T480 does not. T480 needs a PCIe card such as Intel XMM 7262.

skullface101 commented 3 months ago

EM7455 is usb over PCIe and its working in my T480 I have another one which is not unlocked I need to unlock it

skullface101 commented 3 months ago

all my cards are M.2 WWAN form factor and all same model with different Brand/FRU I have lenovo T460 FRU and Lenovo T470 FRU and Dell FRU and btw i once had an unlocked DELL EM7455 working in my T480 but i swapped it wth a lenovo one with my friend who has a dell laptop

I figured out that was a mistake because dell version supports 2 more 4G bands

skullface101 commented 3 months ago

Oh btw i have the same issue with my T470, the whitelist makes me unable to work with the dell card

M.2 is a physical form factor not an interface, all the documentation i found online points to them being usb only and using the m.2 slot's USB ports directly.

If you need configure the card differently than it currently is, you need to figure that out yourself as this seems more of a card issue than a whitelist removal issue.

the cards works in dell laptops and usb WWAN adapters
