Re: ThinkPad T14 Supervisor password

can some one help me?

What kind of help do you expect? All answers was given. Blank eeprom region in EC (jtag) After this you need restore dmi. In my case I still had product name error after restore. It was solved by golden key.
Info in eeprom can be decoded by xor FF

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.

rt809h + read MEC1663 + write MEC1663 after that you will have to fix the bios information.

Re: ThinkPad T14 Supervisor password

after doing the MEC16xx writing procedure the machine loses the information, so when using the LMU to write back, just writing some information fills the others, just start writing back the SN then the SN of the motherboard, vera that some other information will already be there, the UUID code is generated automatically by the LMU, that is, you only need to know the SN of the motherboard, the SG and the machine model, nothing more.

Hello 69d0b913,

Is there any way to read the configuration before overwriting it using the HMD/LMU ?

By the way, what is the difference between HMD and LMU ?


Thanks

Re: ThinkPad T14 Supervisor password

Hello everyone,

Any update on how to remove supervisor password in EC / ITE ?
Pretty sure it's just a procedure similar to MacBooks with replacing "FF" to some region in the dump.

Thanks !
