Hello,
Could someone can check my bios dump, is it correct?
The laptop is CF-54JU003TG
I used afuwingui for windows to make the dump. After when I tried to flash it, I received error 43 - that can't be eraced the rom. After restart, the laptop is stay on black screen. I tried to flash the bios with CH341A with original dump, but the situation is the same.

Thank you in advance.

This is the first dump:

Afuwin failed to create a complete backup file.

Thank you for your response hoaca388.
What kind of options I have right now, can I use another BIOS.

Hello, I've been trying to get Windows 10 on my Panasonic cf-54 and I tried everything but it seems I have to access the BIOS anyway.. I found someone online but he's asking 20 usd for it and I read on here to surely not pay for it

So here's the question: could anyone help me find my BIOS password? Can't seem to figure it out to do it myself..

thanks in advance!

Try this.

What device did you use to create your backup? I'm afraid it's only half. This device password cannot be decrypted but it can be erased, so look for a programmer device to read the bios chip and be able to rewrite the new bios to the chip after removing the password.

Thanks for the reply hoaca388, I will search one and try again
that explains why it didn't work when I tried deleting it myself

Hi,
I bought CF-54 MK1 used years ago with open BIOS, without password request.
Recently I accidentally set the BIOS to default settings, since then it has asked for a BIOS password.

Can't fully use the device now. I'm desperate, please help.
Many thanks for possible help!

PS: Dump read with AFUWINGUI 5.12.03.2045

Hello mate!

Thanks for the quick work and help!
Unfortunately, I don't have a flash tool at hand at the moment, but I think the problem has been solved...
I seem to have been blind and missed the PW requirement thread that you corrected. Thank you very much!

When I get my hands on the hardware, I'll report the results.

Unless you can give me a tip on how to carry out the flash procedure using software. If possible?
Then case can be accelerated.

Thanks again and see you later...

You can use the AFUWINGUI to flash the bios. Start AFUWINGUI, open the unlocked rom and flash it back.

I've tried several times with different options...
Unfortunately, this is not possible (please see below)

[WhateverGDR]

Looks like your flash is write protected. In my opinion, only a CH341A programmer can help. But since you can't use this ROM! You then have to read out the complete bios with the CH341A programmer and then have it unlocked again here.

I have already ordered exactly this tool and am now waiting for delivery.
There is one more question: Should EEPROM be unsoldered, or can programming be done directly on the board?
Thanks!

[WhateverGDR]

You can try it on the board first. If that doesn't work, the chip must be unsoldered.

Hi, can I use one of the bios files with password already removed or is it necessary for someone clear mine? File is from CH341. Thank you.
