3.7.3. Flashing EC (SMSC MEC, 2019-*)
On the latest generations of ThinkPads, the security issue that allowed to inject the DXE driver and bypass the password does not exist anymore. The password is still stored inside the EC, in a write-only region.
However, it appears that dumping the EC with a dedicated programmer, erasing it and flashing back can actually clear the password. See: https://www.badcaps.net/forum/showth...t=95736&page=5

Hey guys,
have a laptop here that has a supervisor Password (dump in Attachements).
Before i write the Serial NR.etc i wanted to say that strangely after flashing with 3 different Bios dumps and one from lenovos site
the laptop works but everytime it wants me to type a supervisor password i never set.
I thought the supervisor password is stuck in the ec bios but no it isn't either because after replacing the ec chip from one of another board it still has the supervisor password.
Anyway i wanted to ask what of the two chips is the ec bios because on the left... -
Hi all, I'm new here, a few words about myself: CS student, interested in hardware stuff too - tinkering my whole life but with practically no experience when it comes to firmware "hacking".
So I have this X380 Yoga with a supervisor password in place and before doing anything stupid I figured I'd rather ask.
I plan on using the tool from this thread: https://www.badcaps.net/forum/troubl...password-remov... -

Good day, everyone!
I'm encountering an issue with my Lenovo X1 Yoga 5th Gen laptop related to the BIOS supervisor password. I'm seeking assistance and guidance from the knowledgeable members of this community in resolving this problem.
I am no expert and cannot perform soldering or unsoldering of the chip from the board. Therefore, I attempted to use an EZP 2023 programmer with a clip to extract the BIOS bin file without removing the BIOS chip from the motherboard. The BIOS chip has the following letters imprinted on it: "Winbond 25Q80DVNIG 2026". I used the... -
I have a laptop that was purchased second-hand, and I am able to boot Windows on and extract the BIOS dump (ONLY the BIOS region, I was unable to dump anything else due to an FCERR I received trying to dump the other regions) and use normally. However, because the BIOS is locked with a supervisor password, I am unable to use anything else except for Windows, and it has also disabled some hardware features of the laptop itself, such as the fingerprinting module, etc. that I really do wish to use.
I have been digging around for nearly 2 weeks trying to find any mention of the same model...
