I have a bricked ASUS AC3100 router that I have interest in reading/flashing the BIOS with a CH341 programmer and SOP8 test clip. The problem is I have very limited hardware knowledge. I removed the casing and took pictures of both sides. I know I'm supposed to remove the battery and find the BIOS. However, it doesn't look like it has a battery and I don't know which is the BIOS chip. Can anyone help identify the BIOS?
