Panasonic Toughbook CF-C2 please remove bios password!

@Andreasbest
The default supervisor password may be found in other forum (have sent you a pm), the point is that most likely this laptop may be one like the ones used with diagnostic tools in service centers (VAGCOM VAS ODIS), on which it seems they set a default supervisor password on these. I was also checking other 2 Getac bioses, one from a B300G4 and a V110, at least one of these laptops has BOSCH on the bottom and both of these laptops have also a hard coded supervisor password in them, every time we try to reset them the supervisor password remains set after reboot.

What programmer are you using? The ACPI BIOS ERROR you get while trying to load an OS may be due to some of the bios modules being probably damaged (according to UEFITOOL which report invalid data checksums).

@aaac thank you for the passwords i'll try them.
Although i highly doubt the unit is from diagnostic center.

@AAAC As i suspected none of the passwords worked, was a Federal Government machine.
@smdflea the bios.zip is not working, asking for password right away.

Ladies and Gentleman we have a winner!
The bios2 works like a charm, supervisor password is clear, uefi works, usb boot devices unlocked and finally "restore defaults" doesn't restore any supervisor password!
Now tell me, WHERE THE HELL WAS HIDDEN???

Thank you very much mate!

p.s: i keep testing as there is no bios update for these machines to correct everything.

You need CH341A programmer

thank you so much for your reply. could you please help me with the wiring diagram of that programer and where do i connect it in my CF-C2 ?

[Andreasbest]

Re: Panasonic Toughbook CF-C2 please remove bios password!

There is option to buy it with 8pin flex clamp that fits 100% in the bios chip, in my case though this was impossible (never figure out the reason) and the programmer didn't recognize the chip so i have to desolder it everytime and solder it on a small pcb that comes with the programmer to read it and write it.
But now since the bios is ready you will have to do it only once

Re: Panasonic Toughbook CF-C2 please remove bios password!

Unlocking password is possible, problem on C2 M series is that after "set bios default values" the password returns.
This is why SMDflea build this specific bios.

@Andreasbest
I got the programmer and the 8 pin flex clamp cable. I will try and update the chip with bios2 file from SMDflea.
So the bios chip is the one that reads 402R6? Correct?
My machine is asking for a password when I switch it on... It doesn't even let me enter the bios... Do you think its a supervisor password or a user?
Would flashing it with bios2 resolve it?

Apologies... Just wanted to know if such claims are legit.

[saurabhhsrivastavaa]

Re: Panasonic Toughbook CF-C2 please remove bios password!

OK.. So I tried and tried but couldn't read the chip

I had to desolder the chip, but my chip has something else written on it. I tried both the chips, it reads but I think it is not correct as I get FF and somewhere 0 also... While writing it gave error on both the chips buffer is greater than the chip...

panasonic CF-C2 unknown bios password.

Hello all,

i recently acquired a cf-c2 with a password protected bios, previous owner has no idea what it is. The laptop is possibly ex police stock...uk.

so far i have dumped the bios using aptio afu tool....and then tried to decrypt the bios password stored in amitsesetup.

i cant seem to get any values to return that correspond to ascii scan codes.

this is the hexbody found using UEFITool NE....

0BD0660EC12E1C527716D2A92D3D88D0
E3633EF7998AF41D4FB1AA4405D8606B

considering i stumbled upon another thread here about editing the bios and flashing it over a clip.....i am starting to wonder is this because the password is SHA 256 encrypted.

any advice from someone with some knowledge in this area?

thanks for reading.

passworded bios attached
