Panasonic Toughpad FZ-G1 Bios unlock

[ripperdxb]

Hello everyone, hope to learn more of this process as I'm completely new to this, can someone help me with the bios password, please find the attached dump. Any help is appreciated.

Have you suitable hardware programmer?

[ripperdxb]

I have but I know it can be done without opening the tablet and I don't want to open the tablet. People can do through the dump.

One of my next projects is the FZ-Gx series.
In my case we use a "Donor" .rom file from a clean system.
Then use either Aptio4 or AptioV to flash the NVRAM.
Flashing the whole BIOS will duplicate the exact model and serial number.
When I get some more info I will post here.
Best regards,

Thank you, I'll be waiting eagerly. I have seen people doing it in like within 5 mins, take the dump .rom file and change or alter the password area and flash it back again. So I know it can be done without physically opening the tablet which is a good thing and knowledge to have.

If you can log into windows you just use Afuwin to backup your Rom and then find and delete the password using UEFITool and HxD editor.
There is a video on Youtube on how to do it and well explained. He did remove the chip to flash but I'm quite sure you can reflash the Bios from within windows or DOS.
Don't know if I'm allowed to post the link so, go on Youtube and search for "How to Clear / Remove Lost BIOS Password"

I'm on the same boat here, but I bought a pack of 8 Fz-G1 for parts, at least 3 of them work but are locked, the seller hide that the had passwords and as the don't have OS installed I'm trying to backup the Roms with a CH341a but no luck, always end with bad backups... I'm sure I'm setting the Ch341a wrong, but don't know how to do it properly for this chip, a N25Q128.

@DeathBringer and others, If you can guide me how to make the backup it would be great!

Thank you in advance
