HP BIOS unlock tool

Re: HP BIOS unlock tool

Good morning. CH341a programmer using v2.1.0.13 ASProgrammer to unlock a HP 830G7 w/HP SureStart-protected BIOS password. Read function displays almost all FF's but doesn't error, says "Done" when finished. Drag/drop to HPUnlocker tool works fine, produces unlocked bin version as advertised. Programming that bin file back on to the chip results in continued request upon boot-up for a BIOS password from SureStart. Unlocked bin file attached as well as the read file after "hopefully" programming it back. Not sure how to read those files to confirm if what was written back actually took on the BIOS chip. Any help is greatly appreciated.

Re: HP BIOS unlock tool

I have a hp 9470m, Supervisor passord lock. I have bought a ch341a. the NeoProgrammer V2.2.0.8 is the only app I found able to detect the chip 25q128a 13EC0. but it shows verify error after reading the chip as in the pic. and it also shows an error message when trying to patch it. Can someone please help? Thank you!

you probably don't have firm contact between the programmer and the bios chip...

Re: HP BIOS unlock tool

Many thanks for this amazing tool. Worked great on my admin PW locked HP Probook 6470b. Can also confirm this tool only removes PW - all other data is retained (DMI etc).
Great stuff!

Re: HP BIOS unlock tool

Hi,

I just tried the tool to unlock the BIOS password for Probook 5670b. I read the chip with CH341 programmer and used the HP Unlock Tool. Erased and reprogrammed the chip with provided .bin file. Everything went very well without problems.

I did disconnect the bios battery, reconnected and powered on the machine but looks like BIOS is disappeared. F10 doesn't work.

Any ideas what could be probably wrong?

Thanks
