    Hi everyone,
    I have a CF-53 MK2.
    I was able to dump and remove the BIOS lock (user and supervisor password) and flashed it back with a programmer and was able to get into the BIOS.
    I did a Load Defaults and now it's asking me for a password.
    I can flash the unlocked file again, but maybe someone can point me or remove it all from the dump.
    Is it possible to get the Panasonic Logo on boot again, because there is a custom one installed.
    Attached is the locked bios dump.
    Thank you!

    I already figured it out myself and deleted the passwords on these versions as well.

    I'm sorry.
    Model CF-532SLZLNM S/N 7HTSA15216

    In the second case, there are no stickers with serial numbers. There is only FCCID: ACJ9TGRI12A

    It just asks for a password again. In the second case, BIOS CF-532SLZLNM shows a black screen.
    2 original dumps with corresponding names in the archive.

Because, I ask you for a complete instruction for working with the BIOS chip.How i can upload bios ? What should I do first? If u have Video instruction for working woth Panasonic bios chips please share this video and i try to do it.
