Hi to all,
I've tryed to remove an 8FC8 bios password. I've dumped and modified a specific block with an HEX editor and i've reflashed the chip but i'va made a mistake. I've readed the chip with another chip model preset, specifically with W25Q256 and probabilly i've corrupted the data. It's has happened because on my XGECU programmer that chip is not supported and i've tryed to read with other preset (disabling the model check). At the end i've found the right spi model on ASprogrammer used with CH341A programmer. I've tryed to programming it many and many times until i've broken the IC and now i must also replace it.
My question. I know that the password is stored on EC so it's enough to change and reflash a new IC with a same motherboard model dump and then with the right preset read and modify the code of firmware or there is another procedure to restore the system. And, someone can share a Winbond 25R256 dump exctracted by a Dell Latitude 7420?
Sorry for my bad English and thank you everyone helps me!
PS. Before the reworking i've saved the bios main windows picture with all the info as the fw version, service tag and many more.
