Re: ThinkPad T14 Supervisor password

vertyanov or RT809H works always for new Lenovos
Vertyanov is easier no need to solder wires only remove 1 resistor, you can use Keyboard connector to read only eeprom area

Hello, which resistor should be removed? you can firmware algorithm plz, there is Vertyanov 3.1

One resistor is connected to Reset pin. This resistor should be pull up resistor so you just need to move the resistor from pulled down to pull up

Re: ThinkPad T14 Supervisor password

Super password in EC, change directly with EC chips, or use RT809H flash, I come from China

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.

Anyone could help same laptop, same programmer?
I face exactly same error, as a difference I use 24-pin FPC cable as requirement of programmer, with right pinout (from diagram) and nothing...
I found post in another forum about T14S with almost same MB, and same EC and one user read well the chip, and remove the password but with SVOD3.

012: Please use the 24-pins FPC cable and close to Keyboard interface 1 pin with same align direction.

036: Wait for the chips enter into the ISP status, please wait...
037: Wait for the chips enter into the ISP status, please wait...
038: Wait for the chips enter into the ISP status, please wait...
039: Wait for the chips enter into the ISP status, please wait...
040: Wait for the chips enter into the ISP status, please wait...
041: Wait for the chips enter into the ISP status, please wait...
042: Wait for the chips enter into the ISP status, please wait...
043: Wait for the chips enter into the ISP status, please wait...
044: Wait for the chips enter into the ISP status, please wait...
045: Wait for the chips enter into the ISP status, please wait...
046: Boot error, please check whether the EC chip is supplied voltage and ISP cable is connected properly or not. The ISP cable should not exceed 10cm in length.

Adding the battery to the power supply before reading the EC helps in some instances.
