HP BIOS unlock tool

[Jesse James]

Funny thing before I zip the file they are both 16.0 MB (16,777,216 bytes)

Why would this be?

I've read alot on this forum today and not sure to install a new bios and then try to go trough the process of installing all bios information. Not sure its a little more than I can understand at this point.

Because it contains mostly FF characters.

Hello all. I followed the link as best I could. Flashed the bios again. Laptop is fully functional but very slow startup and HP logo sign. I am not sure what file to use if EC needs to be repaired. All laptop info looks correct in bios. I assume that is ME area? I'm confused as this is a bin right from here and every comment says no issues

Any help would be great.

Thank You hoaca388 for all the help. It worked great. Laptop is all working. I've lost some bios information but I will search out the HP tools on this site to help input some of the lost info. I know I came across a bunch of info.

Hello,
yhank you for your help but I have a problem.
the keyboard is out of order (I did not know that "detail") so I did desold and resold twice but at the second time, I swipe one or two components (I'm sure for one, this circle alone, next the white arrow).
I think it was resistors.
Do you have the resistance of them?



EDIT> I found what I need on the forum :-)
Very nice forum here!

Hi

I have an HP 8470p with W25Q128BVFG bios chip. Is there a way to reset the password without dumping the chip using a programmer?
Also all the instructions are for the 8 pins chips. This 16 pins chip is a bit different. Would you please help me here? thank you

No.

You can buy a SOP16 clip to go with your programmer, or if you have the tools to desolder the chip get a SOP16 test socket or adapter board
