Rewrite the SN / UUID after programming MEC for Lenovo
EC MEC1633, MEC1632, MEC1609, MEC16, MEC50
note: Many users ask how to crack the superuser password. This chip is 192KB of Flash plus 2KB of EEPROM (stores the SVP superuser password and UUID). Through the JTAG interface, the flash can be read and written, and the EEPROM can be written but not read. Selecting "MEC1633_256K" to read and write will clear the EEPROM area where the SVP superuser password and UUID are located (the actual capacity is only 2KB). Then use the following tools to rewrite the SN / UUID.

if you program MEC it is very difficult to add DMI

Yes I program MEC. No way? Add DMI to EC dump?

Hello, I have found the solution to program the EC DMI data on newer lenovo thinkpads:

Go to this site and download the package and follow the instructions

GitHub - ASparkOfFire/lenovo-u1-tool: Lenovo Uone Tool for Updating machine's Serial and Model information in UEFI/BIOS.

Lenovo Uone Tool for Updating machine's Serial and Model information in UEFI/BIOS. - ASparkOfFire/lenovo-u1-tool

github.com

With this tool you can program all newer lenovos, is a hacked version of the official lenovo tool.

Hola, no se puede hacer con el maintenance disk, debes usar la herramienta U1 que he subido antes, el maintenance diskette no funciona con los bios uefi.
Lo unico que no podràs escribir es el UUID (almenos yo no lo he logrado) pero todo los demas (SN, TYPE etc) se puede.

Saludos

What is the cause of the lack of S/n?

 

[Laboratorio]

It looks like you are using the Maintenance Diskette software, if your system is a UEFI model it WILL NOT WORK on newer UEFI systems and it shows this error, you must download the U1 tool I linked above, I have successfully rewrite the L4xx - L5xx series, the E14 and E15 too, the only thing I could not do is to reset the UUID, but the serial number machine type system board serial number other DMI info can be set.
The system must be set to boot on UEFI mode secure boot OFF for this to work.
