I have solved it now.
I couldn't get it to work at all by modifying the BIOS. I tried autopatching using volinakis EfiSystemNvDataFvGuid_L390.bin in VOLUMES, also tried manually replacing the sections with UEFITool and even HxD. Each time it would just power cycle on boot.
I ended up removing the password using the shorting LPC pins method.
[B][URL="https://www.badcaps.net/member/237374-smdflea"]SMDFlea[/URL][/B] you can remove the attachment and/or my posts. It wont be useful to anyone as I don't think that file can be patched successfully.
Thanks,...Leave a comment:

Hi, could someone help me unlock this BIOS please.
Lenovo Thinkpad L490

I have tried the autopatcher, and get the tune. I have also tried replacing the section of the bin file that has been changed in all of the successful unlocks in the thread 0x410000 - 4EFFFF. It seem to be the same in all. This just causes it to power cycle.
If anyone could tell me how to do this myself, that would be greatly appreciated.Leave a comment:

Re: HP Elitebook Folio 1040 G3, Password Unlock
Thanks to both of you. I made the same changes to the admin pass section as was made to the power-on and now I'm in.
Is there anywhere to learn how to do this for different makes/models? It would be nice to be able to help out others with this sort of thing.Leave a comment:

Re: HP Elitebook Folio 1040 G3, Password Unlock
Thanks for the amazingly quick response. I have just tried the new file. It has removed the power-on password but the BIOS Admin password is still there.
Please let me know if it was something I have done wrong of if you need the bin file for the other chip.Leave a comment:
