Asus T103HAF BIOS flashed to a new chip not working

[REpairAT]

Hi,
I have an issue with this Laptop. It works with the BIOS attached. But when I flash this BIN to another Chip of the same type and solder it to the device, it won't come on. Power LED is blinking and webcam light turns on. Is it possible that the BIOS is connected to the Chip ID and is there any way to bypass? Thanks a lot!

post the laptop serial number, and the part numbers of both bios chips.

post the laptop serial number, and the part numbers of both bios chips.

Serial is J1N0CX12E527036 and Chips are both W25Q64FWIG

You should change to another chip, maybe the chip you choose is not good.

The story is that I got around 10 of these tablets working, but with a BIOS password and one without, so I just wanted to flash the dump of the unlocked one to the others. Devices are all identical. I tried flashing the dump on two tablets already, they won't boot. And if I solder their chip to the one where the dump originally came from, the screen also stays black.

You can`t just copy one bios from one and expect it to work on another. For one thing, you would have to clean the ME firmware (and copy the DMI,windows key etc). The bios you posted is the one without the password, post one that has a password. It`s an AMI bios, and if the password can be decrypted then the same password might have been used on all of them. If the password can`t be decrypted it can be patched with a hex editor easily to remove it.
