CH341A and gq4x

Re: HP BIOS unlock tool

Your bios backup has the first 16MB written twice ,rather than the full 32MB. The CH341A has some alternative software , AsProgrammer,NeoProgrammer and Colibri.All available on the forum if you search.

Post the 16MB bios backup if it has the second chip ?.

you have two chips, one 32MB and one 16MB on your laptop, write both chips with what I posted ... the 32MB with 32MB and the 16MB with 16MB.

Re: HP BIOS unlock tool

Hi, I have an 840 G3 but I think I have burnt the WSON chip by using too much heat from hot air station.

This board has gold pads above and below the bios chip area which are connected to the WSON pins, so question is, could I replace the burnt WSON chip with a standard SOIC8 chip by soldering onto these gold pins ?

Thanks

Re: HP BIOS unlock tool

Can someone please help me with my 840 G3 BIOS?

It has a BIOS Password, will attach original BIOS-file.

I tried the Unlocker tool but I only get ''failed to execute script HPunlocker''
