Re: HP BIOS unlock tool



Hello RethoricalCheese,

Thanks for your time and reply. I dont understand where this chip can be. I've looked around everywhere. I've found some powerchip but nothing programmable or look like a BIOS chip...

Hello,

New on this board, I'am here to find help/advice on bios reprogramming.

Thank you!

Re: HP BIOS unlock tool

Good evening,

I'm the owner of a HP ProBook 4730s. The bios is locked by a lost password.

I've dumped the bios with a CH341A Programmer. I've tryed unlocker on post 1 but it's not working despite change inside the unlocked file. On the HP website the Bios is 2.5Mb but the chip (MX25L512C) is only 512kb.. I've tryed some to like UEFITool to make is smaller with no luck.

Can you help me to find a way to remove it ? Attached, the original bios file I dumped, the modified (non working file from Unlocker).
