Want to change Serial, UUID etc on HP Elitebook but MPM is locked

[ManniLudde]

Hello,

i hope this is the right Thread. Is it possible to change my serial Number on my Elitebook 850 G5? If so, is there any Tutorial which VErsion of the DMI Tool i need. I tried the HP BCU 4.0.25.1 Tool, there i can only change the bios options and not the Serial. When i try running the wndmifit64.exe the following error is shown:

"MPM is not unlocked. Will not be able to set BIOS settings. Please escalate with the UUID to get SMC blob to unlock MPM.

Thx for ur Help!

Contact HP and give them your UUID and serial, tell them you replaced the board and need SMC.Bin
