Re: ThinkPad T14 Supervisor password

Has anyone read the EC IT8300 chip, from thinkpad T14 AMD, using RT809? Mine is giving an error and even with everything right, would there be any other modification on the board that I do to make the reading? I don't have vertyanov and I don't have svod.

Has anyone managed reading EC IT8300 on thinkpad T14 AMD, using RT809??

Can someone could write step by step guid how to remove password on lenovo T14 gen 1 AMD NM-C80 Rev 1.0? And what if there is something like password-on instead of supervisor password?

Hello everyone, I hope you're doing well.

I need your help, please. I'm trying to understand if it's possible to remove the supervisor password on a Lenovo ThinkPad T14 Gen 4 (AMD version).

I've read several threads on the forum, but I couldn't figure out which method actually works for the T14 Gen 4 AMD. Some mention using a motherboard jumper, others talk about a special USB key, and I also saw something about using an SVOD4 device.

To keep it simple: Is it possible to remove the supervisor password on a T14 Gen 4 AMD?
If yes, what is the correct method to do it?

If needed, I can provide the required information such as BIOS details, dumps, etc.

Thanks in advance for your help!
