Thank you for your help. It took me time to flash it correctly.

I flashed it using tl866ii Plus Programmer via ICSP port but I was getting error when verifying it. So, I flashed it via ZIF socket and it succeeded without error.

But ! when I started the computer I got many errors related to the EC flash ( invalid RFID, UUID, SNs... etc). I used the Lenovo Maintenance Utility Disk 1.90 to reprogram them. I succeeded on SNs (B0 and C0) but not for the RFID and UUID because I am still getting those errors:

0189: Invalid RFID Configuration Information Area.
2201: Machine UUID is Invalid.

Also, the mouse (synaptic pad) is not working !

Could you please help me?

thank you.
