If it's about the password, there are other solutions.

I did it your way. For Thinkpad X1 Carbon Gen 7th "FX90 NM-B861 Rev: 1.0". I can read the EC dump but it's only 192 Kb
Unluckily, I blew out this resistor. I re-soldered it but the laptop couldn't boot up.
Does anyone know the value of this resistor?
Thank you

Hello Brother

Attempting to read MEC1663 blocks JTAG and prevents the read operation.
s there a way to unblock JTAG and continue reading?

Hi Badcaps Team,

T15 Gen1 with bios lock.

SN: PF2RVTMS

I have checked the dump but I cant find the location of the pass

Try to read 384kB and then you will find the location.

Thanks to everyone for the help.
My case was a ThinkPad X1 Carbon Gen 7 with motherboard NM-C661. I used an SVOD3 and the pinout from the picture I’m attaching. The reset is not needed when using the pull-down resistor.

In the SVOD software I selected EEPROM, and once the dump was read I changed the data from 0x300–0x34F to FF. After reprogramming, the password issue was solved.

Many thanks again to all, and I hope this can help anyone else who has the same model.

I am posting the mec1663 Lenovo T14 nm-c931 1st gen intel 10th that I read, the eeprom address where the password is located is at offset 0x300.

lines 350 and 360 should not be deleted

It's easier to find your way around with the decrypted file

This is what you read, from top to bottom.

I have a Dell e7440 la-9591p motherboard, no matter what I did on the device, I couldn't start it. It uses MEC5075. On the first page, someone shared the jtag paths for tx390, I searched from the schematic and found the same legs. Can I make this read by soldering it in the same way as SWOD? or with rt809f? or what are its legs? Also, I think the place where it says rp1 is for jtag, but there is a resistor with 103 written on it. Can I remove it, solder the 5 paths and 3 gnds and read it?

I followed Maxpower3's instructions and it worked. Follow him, you will also succeed.
Let's thank Maxpower3.
