Panasonic cf-31

Hi everyone,

I have a CF-31 with BIOS password.

I followed posts from forum and followed https://gist.github.com/en4rab/55088...f3039e3c8ab6fd as guide.

I downloaded both Universal BIOS backup toolkit and AMI BIOS flasher (AFUWINGUI.EXE) to obtain BIOS dumps. (Uni. Bios backup results in 8 mb file and the AMI BIOS flasher results 2mb file)

I used Amidecyrptor and AMIDSEDecyript with no luck, the python one gives gibberish decode as password and the AMIdecyrptor gives nothing at all.

When I open dump(s) with UEFI tool to manually decode, I cannot find "AMITSESetup". I cant see any NVAR entry.

I am lost

I need help Thanks

Use HxD hex editor,search for the text word AMITSE

I used .py code and replaced with BINARY data but instead of giving me a sequence it gives me a sha1 hash.

Re: Panasonic cf-31

Thank you for the tip, need further help with ciphered password

I must disappoint you - it won't be the easy way if that's what you think.
From here on, you take the classic way - programmer, dump, edit the dump, reprogram the chip with the edited dump, and so on.

It can`t be decoded,so the selected area wil need filling with zero`s ,there are 2 seperate areas that need filling.
You might have a problem flashing the file back, if you can`t flash back with software then you will have to buy an SPI bios programmer.

He can decode with ease, I am using what you are highlighted, which is

5B 61 B6 46 11 4D 6C 78 C7 BE 22 FD 7D FB D8 5A 33 34 8E AA E9 01 44 C5 9F FA FA E2 55 FF B0 CC 0B 71 66 50 C1 47 1C 1F 77 16 D2 A9 2D 3D 88 D0 E3 63 3E F7 99 8A F4 1D 4F B1 AA 44 05 D8 60 6B

Is there a way to get UEFI Tool NE alpha 51? I looked everywhere but no luck. Just to get the right data.

The decryption algorithm is absolutely different for the Panasonic CF-U1.
The same approach cannot be used in your case.
I told you above what you should do, but of course you can continue to waste your time.

The reason I am trying because I have seen people offering this service, they just ask for dumps (without taking the laptop apart) with software and they provide a password. They ask for complete model number and dump. That means there is a way.

There might be some who know what the newer algorithm is,personally i don`t. If you want to pay go and find a seller,if they can unlock the new algorithm.If you want it done cheaper then buy a programmer,post the full backup and someone here will help for free

Thank you, I am opening the laptop now. Will try to reach the BIOS chip

[wolf3d.exe]

Re: panasonic toughbook CF-31 Bios Password

I finally reached the BIOS chip and took 3 dumps. In the past I cleared multiple passwords but for different laptops mostly hp and dells. Below is the BIN file for the BIOS, what are the steps to take to clear the passwords since I have multiple laptops?

Is it the same method as the poster explains (please see the attached picture)
Will I loose any DMI data?

I ask all these because, I don't want to put this laptop back and see something wrong and disassemble again...... I am sure you know what I mean

Re: panasonic toughbook CF-31 Bios Password

I finally reached the BIOS chip...

The full dump must be 16MB, yours is 8MB?
What is the chip markings?

Thank you for this, since I have multiple of this, could you explain how to remove the password? Thanks again.

Re: panasonic toughbook CF-31 Bios Password

I compared both dumps and noticed crypted password was removed, thank you for the help. It was very valuable. But considering the work I rather make a hole right under the keyboard to reach the BIOS chip
