I did test them pin by pin, all the pins are independent. By the way, why some other user request, only 1 bin file ok, but I need both? Could you explain a bit more? And I did try to load one of clean 5410 firmware to the main chip and the services tag become 7Y9N273-8CF8 in the bios password screen and I could get in read-only bios while I can't even get in bios when I use original firmware and it shows 7Y9N273-0001.
Thanks a lot.

NeoProgrammer should read it ok , but you can try with ASProgrammer and Colibri as well but i don`t think you`ll do any better. The problem is the adapter and/or the soldering, or the CH341A itself is faulty, you can try resoldering all the pins on it. There`s a voltage mod you can make to the black CH341A , try that too, see if that makes any difference , or buy a better programmer.
