Hi tried RCUnlocker on hp probook 440 g7 to remove bios admin password but did not work please help?
have attached original and unlocked bins

When I drag the 32-bit .bin file to the RCUnlocker.exe it tells me to modify the file to make it 16mb. How can I do that? Can someone help me? I also need to know which of the BIOS chips contains the NVRAM because I have a HP 805 G6 mini PC that has two identical 32mb chips in two different places on the board and I don't know which one I have to read, unlock, and write.

on both...use the HxD program (you can find it for free) cut the 32MB bios into 2x16MB use RCUnlocker on both 32MB bios, merge them and write them...be sure to make backup copies without errors so you don't have problems later...

Hello, I tried using RCUnlocker from post #1. I modified the backup .bin of the Winbond 16MB chip, then wrote the generated unlock.bin back to the Winbond 16MB chip.
However, the BIOS password still appears. Please also help me unlock the password of the laptop.
Thank you very much.

Please help! hp probook 450 g3 bios administrator password reset, please!
thanks in advance!

at post #1 you have everything you need...unlock it yourself...

[epoch]

This is a multitool and unlocker for several series of laptops. Works on Windows. No python etc installing needed, all included in package. Everything is tested by myself but since every laptop is not made equally, there might be edge cases. Always VERIFY your file after reading!!!

Unlocking
HP - ProBook, EliteBook, ZBook (including 32MB models)
Chromebooks from all various manufacturers
Apple - everything older than T2
More to come...

Information display (helps to verify file integrity)
HP - ProBook, EliteBook, ZBook (up to 16MB models for now)

Custom logo removal
HP - ProBook, EliteBook, ZBook (up to 16MB models for now)

Usage: Drag and drop .bin file to .exe file.

In case there are problems with unlocking your laptop, write a short description of the issue, upload original file and if possible, _unlocked.bin file aswell. Just crying for help is useless. Keep the topic as clean as possible.

You may ask for feature requests, I'll see what I can do.

rex98 made a Dell-8FC8-Patcher for newer Dell laptops. You should incorporate that into RC unlocker so it can unlock new dells as well without needing to use a separate tool.

Hey, how did you unlock it?
I'm getting the same "Wrong chip. Try reading and unlocking 16MB chip" message too.
Thanks a lot!

There are two bios chips on the motherboard - one, the correct one is underneath. You have to unscrew the motherboard and underneath there is 16 MB of bios. And that is the correct one.
RCunlocker easily removed the password from it and everything is ok.

Thank you very much, SMDFlea , for your help.
I read the topic more than once, and after several attempts, I was able to repair the BIOS file and remove the endpoint message.
However, another message appeared ( Manufacture Programming Mode in Unlock mode).
I used a program (BCU BIOS Configuration Utility)and made a copy of the file(config) from another laptop of the same model, and it worked fine.
But the question here is:
The device data label was previously removed.
So how can I obtain laptop data, such as the serial number, model, etc.?

[SMDFlea]

I need a video to explain because I don't understand the method

I don`t have time to make a video . Here`s your main bios..
