elitebook 850 G7 password

[ERRA]

OK - I double checked again and I did not see any resistors missing. So, I erased the chip and programmed my original backup. Now the machine is back to normal operation with a BIOS password. So, obviously nothing wrong with my soldering. Also, I did a read on the "unlocked BIOS" before erasing it and compared it to the read that I had taken just after writing the "unlocked BIOS" and found they are now different. Powering it up must have changed the contents.

Do I need to do something with the main BIOS as well to remove the BIOS password?

TRY THIS

Thanks, but that did not work either. I wrote that to the chip and then read it back and compared them - they match. I turned on the machine and got a solid caps lock for maybe 45 seconds. It then turned off. I turned it on again and got the same 7 flashes of capslock & numlock.

Post main bios file.

Ok - Here it is. I read it three times and did comparison.

The old file you uploaded before this one is corrupted!
Now try this patch, good luck bro

[duder]

Thank you. Okay, you are saying that the very first file I uploaded (8MB) was corrupted. I can accept that, but the system was working with it. It just had a BIOS password.

My question now is what 8MB file should I use in conjunction with this 16MB file that you just gave me?

The system was working with it, i can accept that! But have you flashed that file back to the chip and pc worked ??

[duder]

Yes, I did flash it back and it worked. But it still had the password, of course. I believe I mentioned all that in my previous posts.

[duder]

Any update? Should I try the file you provided? If so, which 8MB should I use in conjunction with it?

I am tempted to just put it back the way it was and use the machine with a locked BIOS. I was able to install windows if I start the installation in another computer.

Okay - I just flashed that file back and the machine is working ... again. It still has a BIOS password of course. Windows still works. I will just leave it like that. Life is too short for this!

I wanted to try the 16MB BIOS that you kindly provided me with, but you would not tell what to do with the "corrupted" 8MB BIOS.

Please try this combo.
Flash both.

Well, that worked perfectly. Password is gone and there were no security errors. Also, I was able to do a BIOS Update. Any chance you could give a brief explanation of your magic? Maybe I can learn something for the next time. Thanks again for all your help.

Keep your main bios, write the new ec bios I gave you, comment on the result.
