Re: HP BIOS unlock tool



Ahh, of course - I suppose that is the whole point.. LOL - sorry me being stupid.

Again though - thank you for this tool!!! Really helpful!!!!!!!...

Re: HP BIOS unlock tool

In the spirit of something you mentioned in OP re: any improvements.. how about a small feature of producing a log file which details the password that was set..? As example - I have 3 laptops and I suspect they are all set using same password.. Might be able to unlock the remaining ones old fashioned way.. Superb work though!!! - tool is very very useful post HP non SMC help.!!!!

Re: HP BIOS unlock tool

Another success here. Thank You!!! HP 840 G2 locked BIOS - de-soldered MXIC SOIC 8 25L12873F package, read BIN with TL866II, applied unlocker, wrote back, re-soldered & booted to a unlocked BIOS. Wonderful!!!

Re: HP Elitebook 840 G2

So, I bought a TL866ii plus programmer and WINGONEER SOIC8 SOP8 Test Clip - got latest software from manufacturers site - all installed, latest FW on programmer. I have removed the mobo & RTC battery as well. At this point I thought I was almost there,... but for a few hours now I've been stuck just trying to read the chips... In this case I have 2 chips - a 16MB Winbond 25Q16DVSIG /1526 and a 2MB MXIC25L12873F. If I understand correctly I need to read the 16MB chip and then write a password free bin file back to it..?

Anyway, I'd really like to have a go at reprogramming the IC (its a Winbond 25q16dvsig)
I'm about to buy a TL866CS and a Pomona SOIC8 SOP8 Chip IC Test Clip Adapter so I can read (and write) to BIOS - is this the correct kit?
Then I can use the above file posted by imranromi (hp 840 g2...

Re: New Members - please post your introductions here

Hi all, new member here Found the site while looking for a way to remove a BIOS password for an HP Elitebook 840 G2. I've already asked HP for SMC.BIN reset file which did not work - I suspect because previous owner removed RTC battery and system date is way off (HP files have a 7 day window..?)... Anyway, I'm just about to buy a TL866CS and a Pomona SOIC8 SOP8 Chip IC Test Clip Adapter so I can read an write the BIOS. I've been in IT for quite a few years but this will be my first IC (re)programming using such tools. Anyway,...
