i need help for my laptop hp 450 G7 Locked Bios Password

the posted bios is not ok..do not use the clip for writing or reading, you may have errors, remove the bios chip from the motherboard before writing or reading, or pull wires from the chip to the programmer ..

I am using CH431a mini. As it has no Chip type Gigadevice 25b127(main bios chip) that's why writing with Gigadevice 25q128 chip type.

Can you please check the following backup bios chip dumb file not corrupted.

There is a chip named WinBond25q128 after RAM slot. Is it the backup bios chip? Any idea.

Yes, I "already removed" this from the dump, because it needs to be done if you want the bios password to be cleared, so as I said just write back the edited file to the chip. Or if you know better way to do it, fill free to use it.

Re: hp 450 g7

Hey!
Is there a pure BIOS without numbers? How to change serial numbers in the bin file?

[Genyi]

Re: hp 450 g7

Hello!

You can delete data from BIOS: Serial Number, SKU Number, Universally Unique Identifier (UUID), System Board CT Number, MAC Address 1, Asset Tracking Number.

In Hex Editor Neo errors issues.

Thanks!
