Re: Unlock SVP Lenovo Thinkpad T14 Gen2
I don't know if this information can be useful, but the EC file size is 256KB, I took it from Lenovo's official website.
If we can at least write the "clean" file, I think the password would be removed...
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: Unlock SVP Lenovo Thinkpad T14 Gen2
I managed to activate the JTAG interface by removing resistor R4313 and leaving R4411 (not inserted) in place of R4410 (inserted).
By doing this you can recognize the MEC1503 on the Vertyanov and the RT809H
ID found is attached in the image.
But not everything is perfect.
In both tools, reading and writing is not done correctly... the EC is recognized, but the flash is being done incorrectly (like it is blocked).
I'll keep trying, if anyone managed to find anything,...

Re: Unlock SVP Lenovo Thinkpad T14 Gen2
Hello
Things I've discovered so far about this EC.
-Recorders such as Vertyanov and RT809H do not work for this model (MEC1503).
-I think the reason these recorders don't work is because the component's JTAG interface is not being Enabled (I tested with JTAGULATOR), even moving from the "-EC_JTAG_RST" signal to High logic level.
Even placing all 10K resistors on the corresponding lines, the interface was not enabled, making reading and writing impossible.
