HI GUYS
I HAVE HP 650 G8 CONPOTRACE LOCK
DA0X8QMB8E0
SN;;;;5CD120VFLZ
PLS HELP ME WITH THE CLEAR-ME FILE

I have a ProBook 650 G8 with a BIOS password, and I used this script:
https://www.badcaps.net/forum/troubl...y-bios-patcher

Everything went without errors, and the BIOS dump is "patched" (I compared it with the backup and can clearly see the changes). However, when I turn on the laptop, I get a message saying that the BIOS data has been recovered, and unfortunately, the password remains.

I tried running the "HP_Factory_Mode_Full_Script" as well as each of the individual scripts from the archive. Unfortunately, I’m getting the same result. The script is 100% working—it changes the HP_MPM status, and it worked on another HP laptop. I just created a backup using HP BCU and then restored the serial numbers back. I'm very grateful for this script! I used to do all of this manually and didn’t even know such tools existed.

But for some reason, on this ProBook 650 G8, I’m having this issue—the password doesn’t disappear, MPM doesn’t activate, and I only get a message saying the BIOS has been recovered, no matter what I do.

Please, I’m asking for help—what am I doing wrong?
Below I’m attaching the patched BIOS and EC dump, with which the laptop turns on and works, but the password still remains.

Hi, I managed to solve the password problem! The BIOS version was too "fresh," specifically from late 2024. So, I decided to use dumps from another identical laptop, clean the ME region, and use them on this one. There were some issues and errors in Intel FIT (Error 179: [Fit Actions] Failed to parse CSE region), but I managed to fix those as well, thanks to the WinRAID forum. If something isn't working out, I recommend just using dumps from another laptop; it worked for me.

I also noticed that the script somehow doesn't change the MPM state. Here's what it should look like in Hex (search for "HpMpm" in the dump): 48 00 70 00 4d 00 70 00 6d 00 00 00 00 23 01 00 02 00 00 00 aa 55 3f

Nice work..but in the end you didn "t unlock your own dump, you just replaced it with another one, hence the errors.

You write too long, where is the serial number ?

Good day, dear hoaca388. Before disassembling the laptop, I made a backup using HpBCU "/GetConfig:". In the donor dump, I modified the HpMpm state using a hex editor and then restored the serial numbers using the same HpBCU tool. I'm still learning. I’m not doing this professionally. I just work at a recycling company, and sometimes we receive laptops, but usually it's Zebra printers and Elo monitors. So I don’t have much experience.

I have a HP ProBook 650 G8 with a message stating "Devicefreeze-9" and states that it's reported lost/stolen.

Anyway to remove that? I am attaching EC / SPI ROM in hopes that someone can help me clear it.

Thank you, I flashed my SPI ROM with the file you provided and it went through a BIOS update screen and went back to the same lock screen after it was completed.
