Hi, I have a Dell Latitude 3420 with eprom model GIGADEVICE 25R256DYIG and I try dump Bin file with a programmer CH341 but the software doesn't recognize the chip. I tried with and without voltage adapter for 1.8V.

I tried several Softwares versions, but these doesn't works.

Anyone has some ideia why this doesn't work? I read some papers saying that the programmer CH341 doesn't support this eprom 25R256DYIG.

I appreciate any help!

Thanks.

Hey Bios Cracker
Unfortunately, I can’t provide the BIOS dump file right now because I’ve lost admin access and I’m unable to extract the dump from the system without it. is there’s any alternative method ? (I have OS access)

You must have a programmer to do this. The cheapest one is ch341a.
