RCUnlocker

Re: RCUnlocker

Program this chip only, leave the other (main) as is. At first boot reset bios to factory default, then security settings, apply/save and restart.

Many thanks

Is this tool paid?
I downloaded it to test on an HP ZBook 15 G3 Mobile Workstation APW5U LA-C401P with PASSWORD, but it doesn't show anything but 3 messages.

Re: RCUnlocker

HP Probook 450 G6 here, had a bios password and I was able to dump the bios and use the tool which shows all of the laptops info and said unlocked. Upon writing it back the laptop will only boot to a screen that system locked press enter to restart and it does that over and over.

One thing I did notice when reading the bios is it gives me two options once it detects it and it will read from both.

Thoughts?

You need a SPI programmer...extract the content of the bios chip, use the program from post #1, and back to the chip with the new content..watch a video as an example..

Re: RCUnlocker

This is incredibly fascinating. I was trying to find the bios portion needed from the factory bin and couldn't figure it out. This guy just makes a tool doing it in one step with Bios_region. ��

I'd still like to know where in the new bios you can find the part needed to unlock a locked bin.

Re: RCUnlocker

Well unit refused to boot just black screen and fan full speed, ill desolder the bios chip and reflash it tomorrow.

Hp elite book 850 G5
I used flashrom on a raspberry pi w to backup and flash but I had to export the "bios_region" from the file using "Uefi Tool" to get the RCUnlocker to read it. Would not read the full bin without throwing an error otherwise. I then remerged the bin and flashed it.

Re: RCUnlocker

Well, that is why I put in place the 32MB restriction. You had to modify 16MB chip (on the other side of the board), not 32MB main bios.

Whoops

Re: RCUnlocker

Whoops

OK backup flashed to 32mb chip and unlocked the 16mb one! We are back up and running.

Gotta be the coolest thing I've done since the Xbox 360 "kamikaze hack" to reflash their disc drives!
