HP Elitebook 820 G1 - Still BIOS password after flash

[silversthlm]

Hi,

The problem is that the BIOS is password protected and i have been reading a lot of threads about this.

I bought the "USB Programmer CH341A Series Burner Chip 24 EEPROM BIOS Writer 25 SPI Flash". (had to wait about a month to get it...)

The BIOS i got from HP.

Since im good at electronics and soldering i desoldered the BIOS chip from the mother board without any problem.

Then i reprogrammed the new BIOS and resoldered the chip.

To my dissapointment the BIOS is still password protected.

How can i solve this, is the password stored somewhere else?

I have attatched the bios files, the "bios_backup.bin" is a backup of the bios.

I tested 2 different bios versions from HP and a 3d one which i found here in the forum somewhere.

What am i doing wrong?
