Thumbs up HP Elitebook 830 G5 Admin Bios Unlock

Hi All,

After reading all the threads I have a question, that hopefully someone can help with. I have an Elitebook 830 G5 and I am trying to remove admin BIOS password with the unlock tool

Looking at the mobo, I have THREE Winbond ICs and I am not sure which one (or in which order) I am suppose to re-program.

So far, I have dumped and re-flashed the 25Q256JV and 25Q128JV using the unlock tool, but the password remains. I did these separate and powering on the laptop in between each one.

I have just found a Winbond 25Q80DV under a sticker!

Does this 25Q80DV also need to be re-flashed?

Please could you guys tell me what order I need to do this etc?

Thank you
