Re: HP BIOS unlock tool

I always get the attached Error. I put the exe and the file from Chip directly to C:/ but still no change. What could be the Problem?

Hp elitebook 830 G5.
I am writing via google translator, so sorry for the mistakes.
What chips need to be soldered and from which to write off information, I have three of them?
After I read the chips, can I modify them via HPUnlocker_v1?

Re: HP BIOS unlock tool

Re: HP BIOS unlock tool

For the BIOS dump. Im having some issues. No matter how I try to read it with the 341 programmer with software Asprogrammer with both ver 1.4 and 2.0. Every read of the chip brings up all FF FF ..
I am not sure if the chip is encypted to show this or if the chip is bad.. or if the issue is with the connection. the chip is on the circuitboard, battery is out of laptop, and its not plugged into the charger.

I did bios upgrade 1.51 after password unlock. It was working fine but after couple hours it started behaving weird. So I thought it might be soldering fault and tried to heat up the chip with no success. I was able to backup 1.51 backup from the chip but I feel that its corrupted based off comparison with another laptop backup.

I am attaching it here.
So far I tried older bios version 1.39 unlocked backup but nothing worked.
Same LED blinking pattern that shows logic board failure.

Oh BIOS is empty, I think that's the issue. I am not able to read the chip now , It seems damaged. My programmer reads another Winbond chip but not this one.

I have old bios 1.13 backup. I am attaching here.

Requested information :
Model : HP EliteBook G3 Touch i5 6200
Logic Board : 6050A2892401-MB-A01
