Hi to everyone. I wrote this request because i've tried everything but i can't resolve my problem. I've an HP HP ProOne 600 G6 22 All-in-One with faulty motherboard and i replaced it . The new motherboard had different Product name and serials but was not a problem. The main problem is that with the new motherboard the touchscreen not worked so i flashed the old bios from the faulty motherboard. Same problem , no touchscreen and all DMI get from EC , so i reflashed the EC with the old motherboarboard and now touchscreen works fine and all DMI data are correct but every time i boot the PC it gaves me "Endpoint Security Controller Problem" and i don't know how to resolve . I've tried to clean ME on main BIOS but nothing changed.
I think that the problem is because the System Board CT number and MAC adress doesn't match with the new board so it gave an error but i don't know how to resolve it.
I attach the original BIOS+EC from old motherboard and from new motherboard , maybe someone can help me in order to have full working touchscreen and Endpoint controller error gone.
These are the identifiers for the motherboards:

Adding the build ID and feature byte might solve that. Have you tried editing the config file or using Bios Config Utility
BuildID and feature Byte are ok .
I don't edited anything because i can't enable MPM mode.
If i use NEW BIOS and EC the PC Boots without endpoint error and with DMI data of the new spare board but Touchscreen not working, It i use OLD BIOS and EC (From the original motherboard) PC Boots with working touchscreen but it gave endpoint error..

Anyway i've solved the problem injecting official BIOS firmware from HP support site in the BIOS Region of the old motherboad BIOS backup . Flashed the original EC file from the old motherboard to the new motherboard (in order to get enabled touchscreen) and flashed the BIOS region free file.
PC boots in MPM mode , after filling DMI data with BCU and rebooted everything works fine without endpoint error and working touchscreen.
