      Need some advice on what bios chip programmer to buy, I got a CH341A to try and flash a chip for a macbook a1708 but had no joy at all with the software just constantly throwing up errors. So I’ve convinced myself I need a good quality one as I am getting more and more laptops and macbooks that I need to replace bios chips on.
      Anyone with any experience in this giving me some advice on what hardware to get would be much appreciated

        I have tested 3 programmers

        TL866II Plus
        EZP2019 High Speed
        CH341A V1.7

        Over all the software that comes with the TL866II is the best IMO They do have a new version out but its like $200+. The EZP2019 works good. The down fall of these 2 programmers is you have to sandwich boards for the correct volts for that chip your programing. The CH341A “V1.7” is had a voltage adjustment switch and it works. Bad thing is the software is blah. Over I would suggest the TL866II over all of them.

        Quick question. Are you flashing in circuit?

        I hope you fluxing fix that.

          Thanks for the reply,
          I’m currently inundated with macbook repair, I’ve refused to touch them for years due to a real dislike for apple but had to take the step due to high demand, this first one I’m having problems with is a A1708 macbook pro, I have removed the bios chip but just get sporadic readings and errors when trying to erase or programme the chip using CH341A that I purchased, it seems to read the chip fine then just give me errors, I tried like 3 other versions of software that claim to work with this programmer 1 of them even verified the flash and said all is good but I just get a touch pad click and a blank screen on putting the chip back, I know the bios file is good so am convinced it’s the programmer / software at fault

            Chip programmers will be in stock later this week. I’ll update the post when when item is available for purchase.

              Did you look up the data sheet of that chip to see what voltage the chip is? I have seen issues with under volt programmers causing issues.

              I hope you fluxing fix that.
