    Cannot read cFeon QH64-104HIP bios chip

    Hi, I tried to read my laptop's bios chip with a CH341a but there is nothing similar to QH64 to choose from the software's list, only 25Q64 but that didn't work and the auto-detect couldn't identify the chip either.
    What could be the problem?

      Datasheet

      User @exetico was able to read it, his auto-detect said EON EN25Q64 (thread).

        I think my programmer is not working correctly, I tried it on two other chips and it can't identify them, and reads only FF or 00 but Windows recognizes it and I hear the new device connected sound when I put the clip on the chip.
        This is my second CH341a that stopped working.
        Does anyone recommend getting an EZP2010/13 over another CH341a?

          you should fit the chip in the programmer before you connect it to the usb

            I tried every combination, I think this programmer is dead.

                To make sure the problem isn't the SOIC8 clip I desoldered a W25Q64FVSIG from an old tablet and soldered it directly to the adapter that came with the programmer, it still couldn't identify it or write anything, it was already empty.
                Then I saw a 25P05AV on an old IDE hard drive and to make sure the problem isn't the 1.8v adapter I tried that too and it still couldn't identify or read it, reads always 00 00 00 00.

                  Same thing happened to my own ch341a programmer, it went dead after the first use

                    i have ch341a and ezp2019+
                    but u need to solder a wire on pin 4 and gnd on the ezp, or it does not or less chips,

                    even the database of supported chips on the ezp software is bad,

                    so yeah the ch341a is way better with chip support
