Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

[QUOTE=Knucklegrumble;984697][ HOW TO USE THE PATCH ]
STEP 1: Flash and replace current BIOS with the generated patch file
STEP 2: Boot the machine
[B][COLOR="Red"]STEP 3: Press ENTER/F1/etc. to enter BIOS settings

After Step 2: I cannot enter BIOS by pressing Enter/F1/etc. The machine does not respond to key presses at all. And I do not see the string with a prompt to enter the BIOS. I see only one string as I wrote: "Press Enter to interrupt a normal boot order".

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

It seems my BIOS dump is corrupted (see a screenshot). Correct?

But after reflash machine by original (corrupted?) BIOS I get machine with normally booting Win10.

I can't tell by the screenshot if it's corrupted.

What model is it? Can you post your original bios dump?

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

test

Test did not passed. I see the same thing. After power on I hear 5 bips and 5 bips, then a black background with the Lenovo logo and the line: "To interrupt normal startup, press Enter".

If I press Enter, nothing changes.

Did you hold down the anti tamper switch and removed your hard drive?

No, I didn't. I'm so sorry! I was hoping that without him everything would works. And during the flashing I completely forgot about it. And I don't know how to do "hold down the anti tamper switch". Could you help me with this? Where can I find this switch?

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Thank you very much for help to my dear friends Knucklegrumble and Maxpower3!

It seems all works properly now. But I did not find anti-tamper switch at my machine.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

I tried to patch a T450 but it does not work.
After reboot I can hear 5 beeps two times. After that I see the message "Press Enter to interrupt a normal boot". After I hit enter and pressed F1 to enter BIOS, a black screen appears and the system hangs.
There is no harddisk in the system and I also tried with pressed tamper switch.

This is the output from patching the BIOS:

Using UEFIReplace to inject 2 DXE drivers...
[1/2] BootOption (GUID e0746c42-d3f9-4f8b-b211-1410957b9ff5)
[2/2] LenovoTranslateService (GUID 826bcf56-bac4-43f4-8ea1-8cdf0a121abd)

Looking for volumes to patch...
[1/1] NVRAM_EfiSystemNvDataFvGuid (checksum 2609h):
   Not found... Skipping.

Done.

PATCH FILE: t450-bios-orig-1_PATCHED.bin

Good luck.

Attached you can find the original BIOS dump.
Do you have an idea, what's wrong?

Hard to tell some times with lenovo's... They have the same icons for boot and supervisor password... Can you boot into your os with original bios? Can you enter bios settings? If you can send a picture of the security section in bios

Your're right, it was not the supervisor password.
Sorry for wasting your time. Thank you very much :-)
