    Re: HP BIOS unlock tool

    Hi there!

    I have a Elitebook 850 G2 that has a bios password. I dumped the bios with a CH341a programmer and tried to remove the password with HPunlocker and RCUnlocker, but the first generates the same image (do not make any changes to the bin file) and the RCUnlocker software says "Missing Unlockable content".

    Can anybody help me? Thanks!

      also look for a bios chip with a content of 16MB... look on both sides of the motherboard and use RCUnlocher...

          Hi all!
          Is HP EliteBook 840 G5 better to unlock with HPUnlocker or RCUnlocker?
          I also need to replace the battery.
          What is the best way to unlock or replace the battery first?

                Its the wrong chip as RCUnlocker says. There are 2 chips U365 + U366 .Find the other one and try it again.

                  From another Thread. you need to backup the U366 Chip.

                              ok this is a update. i presume nobody looked at my attachment, but this is what happened.
                              I copied the bios chip to my pc as this:
                              W25Q128JV(OTP)@SOIC8 and i unlocked it with HPUnlocker because RCUnlocker didnt work and programmed it back and it didnt work. so i programmed the original file back.
                              What i had to do is read to bios chip as:
                              W25Q128JV@WSON8 without the (OTP)(i dont know what this is) then the RCUnlocker did work to unlock it and programmed it to the chip, soldered it and now the password is gone

                              so what happened is i chose the wrong chip in the programmer, but it did read and program so i assumed it was correct bu it wasn't

                                      The tool works great for a HP 640 G1. It unlocks my Administration Password!

                                      Thanx a lot!
