NEED BIOS FOR HP EliteBook 840 G5 6050a2945601-mb-a01

[iaf86]

Hi, experts. I have an HP Elitebook 840 G5 with a locked bios password. Is there a method to remove the password without an EC chip? I can successfully remove passwords using patchers and RC unlockers, but I'd like to learn how to remove passwords using the main bios chip. I tried the HP unlocker, which created the unlock file but did not work. I attempted to delete the bios password manually using Hex editor and the Usercred method, but it did not work. I am posting the 32MB bios password locked.

That dumps worked for me on several 840 G5 laptops.
First , you must check all components near the EC and BIOS chips to ensure you have not blow out any little resistor and second sometimes it takes a long time to boot for the first time after flashing both EC and BIOS and I mean even up to 5-10 minutes with several restarts.

Thank you sir, I will give it a try again sir

Thank you so much for your swift response. I appreciate it so much.
So after flash the EC & Bios you provide, I get a steady white light with 11 amber then 6 amber blinking then restart.
Please kindly help me in anyway you can. Thank you

Your provided serial does not match any of the dumps provided...in fact the two dumps are from different laptops...anyways,
here you got two dumps (EC+BIOS) but you need to use BCU tool to enter factory data ... from your provided bios content is this:
