Chosen Solution
Hello, First, let me give you a little bit of context of the problem. I am semi-experienced in Apple cell phone repair and know how to replace screens, batteries and that kind of stuff. To further expand my skill, I have second hand brought an iPhone 6 Plus with Wi-Fi problems and the infamous touch disease. To solve the problem with the touch disease I have brought a new motherboard from Aliexpress and have swapped it. At first it look like everything was working (No Wi-Fi issues and no touch disease problems) but when I plug in a charger I immediately got the “accessory not supported” error. Of course I have tried all the default steps; Different chargers (Including Apple original) > No difference.Different cables (Including Apple original) > No differenceEven connected with the original USB-C to Lightning cable connected to my 2018 MacBook Pro I get the error, while there is no problem with iTunes /Xcode data transfer.Recovery of a fresh iOS trough iTunes also does not make a difference So I have thought it was the charging flex cable (from opening it up to replace the motherboard, it looked 3th party to me and not original Apple). So I have ordered a new charging / dock connector flex cable and swapped it, but it still gives me the error. Also when I again try the above steps and does not make a difference. The only strange thing I have noticed is when I try the steps to enter DFU mode;
- 3 Sec powerbutton
- 10 Sec power- and homebutton
- 5 Sec homebutton The screen immediately lights up with the Apple logo when pressing the powerbutton, instead of waiting 3 seconds. Also when powered off the device is charging, but not when powered on. Do any of you guys can give me a clue to go from here and/or what to try next to fix it? Thanks in advance!

It’s either Tristar chip needing to be replaced or components near tristar chip needing to be replaced, sometimes it’s one capacitor / resistor missing near tristar. It will require micro-soldering to replace chip or components on the logic board.
