It works. After a few tries, I managed to connect.... -
Łenovo Thinkpad T14 AMD Gen3 21CG
SN: PF-47FFJS
MB: NM-E441 Rev. 1.0
Hello, guys. Maybe you can help me. The problem is that SVOD4 doesn't detect the NCPX997 in my T14 Gen3 AMD. The programmer is activated and the latest available software and firmware are installed. The connection is fine; I checked. Maybe someone has an idea how to get the programmer to work....Leave a comment:

Many thanks. MaxPower3. On point as usual. Password removed....Leave a comment:

Yes, but I don't have the original MEC 1663 file read. I won't have anything to flash after cleaning. Maybe one of my colleagues has a clean MEC 1663 file saved for this model. Unfortunately, I don't know how to make one myself....Leave a comment:

Lenovo Thinkpad Carbon X1 Gen 7 SN: PF-21L93G Motherboard FX490 NM-B861 Rev: 1.0
Password on the board.
I connected the board to the JTAG connector and moved the resistor.
Unfortunately, I get the message
MECxxxx series in protect mode, work mass erase only
SVOD4 reads the entire batch and EC MEC1663 BA0, but there are only 00s there, the batches are empty.
And I can't upload the decoded EC batch. What else can I do to unlock the MEC system for writing?...Leave a comment:

All I had to do was upload the batch file with my EC, the one I provided in post #180, and all the data was there. There are no more errors. Thanks again....Leave a comment:

Thanks a lot. It works. The BIOS has been unlocked. I just need to add the SN and other data and the procedure is done. Thank you to everyone involved....Leave a comment:

Will someone try to unlock and clear this BIOS?...Leave a comment:

I have both batches ripped. Maybe someone can help me unlock them....Leave a comment:

I have two SPI chips on my board. One is a 25B512MFYIG, the other is a 28B128ESIG. Need to clean two batches?...Leave a comment:

After pressing F1 the password is still there. All functions in the BIOS are unavailable and cannot be changed....

I temporarily connected the battery, and now I can access the locked BIOS. The password is still there; I'm prompted to enter it immediately after powering on. All model data is erased. I took a few pictures of the BIOS. When I try to exit the BIOS, a message appears....

I hope it will be possible to unlock it. I've been struggling with it for a month now, and there's no result. Unfortunately, I have no experience editing EC\KBC batches, and I don't want to completely damage it....Leave a comment:

Now, I can't access the BIOS. After entering the incorrect password three times, the laptop shuts down. I have screenshots of the BIOS taken some time ago, showing how I was able to access it. I haven't tried flashing the FF file alone, as I'm afraid the laptop will be dead after that....

I've already uploaded this unlocked file from the AMD platform. These 4 errors appear and the laptop immediately shuts down.
The problem here is the SVP error. I already have a manually edited file from my batch that also has the SVP error. Maybe you guys can fix it there....Leave a comment:

This unlocked version of the attached file does not remove the password...Leave a comment:

After installing version 4, it's the same. It still asks for a password....Leave a comment:

After installing version 3, it's the same. I'm still asked for a password....Leave a comment:

I uploaded this file. There's no SVP error, but a prompt appears with errors. Picture one. After pressing F1, the password appears. Picture two. After pressing the "Click Here" link, a string of characters appears. Picture three....

This batch file with SVPerror in its name is already edited by the author of the "Universal Bios Tool by Andrew" program. I included the original, unedited batch file in my first post requesting unlocking. I don't have the knowledge to edit it myself, so I'm turning to more experienced colleagues here on the Forum for help in resolving the password issue....Leave a comment:
