Re: HP BIOS unlock tool

I've done everything. And why is the red line "system is booting in manufacturing program mode" now shown at the top? What does this mean?

Everything is checked in detail down to each character. There are no errors.

There were 20 reboot attempts. Each time, the number decreased by 1. After 20 reboots, the inscription no longer appears, but the PASSWORD again appeared to enter the BIOS.

Now I understand, it is necessary after unlocking, on first boot, BIOS needs to be reset to factory default. Only after entering the MPM data.
For this you will need to program the BIOS again.

Re: HP BIOS unlock tool

Let's agree on the exact sequence of actions.
1. I solder and reflash U365 again.
2. I turn on the laptop, go into the BIOS and install MPM. I save and reboot.
3. I go into the BIOS and reset the settings to factory settings. I save and reboot.

So to do?

Or swap steps 2 and 3?

No, it doesn't work. After flashing, I immediately reset the settings to factory settings. After the reboot, I entered the MPM data. Still the red inscription comes out. If I reset the settings again, the MPM information disappears, and the number on the red inscription again goes from 33 downwards.
He does not like the MPM information, although I enter everything correctly, I tried it several times and double-checked it several times.

I found a solution to the problem.
While the BIOS lets us in and allows us to change the administrator password, I set my password. Then he rebooted 33 times until the red inscription disappeared. After that, the BIOS asked for a password to enter, and my password worked!

@alimcorp
It's not necessary... But that's ok!
The important thing is that you got it resolved.

New file

Re: HP BIOS unlock tool

New file

Thanks hoaca388, the file you posted is exactly the same as the file i have written to the bios already. Did you alter any code in the file ? OR did you just unlock it with HP-Unlocker tool ?....Because it is identical to the file that's currently in the BIOS chip, see picture

Re: HP BIOS unlock tool

No, i was build a new file from your file. Of course it should be 16MB.

Re: HP BIOS unlock tool

Thank you guys for your advice.I really appreciate that.
Do I have to remove the chip from motherboard or I can use clip attachement with EZP2019 programmer?

I never got it to work with the clip, so my advice is to remove the chip.
Did you check the chip on the upper side towards the keyboard, or is that the chip you are referring to here ?
