iPhone won't charge. "This accessory is not supported"
Hi everyone. My iPhone 3gs won't charge fast enough.
Every time I plug in my iphone 3gs to charge, it keeps getting the error message: "This accessory is not optimized for this iPhone". And even when it does charge, it will have that message, and it takes 30 minutes just to charge up 5% of the battery
What I have done=
-Replaced Charging port 2x with brand new parts (Mengtor & Wireless parts inc)
-Cleaned the board and all chips and possible connections with isopropyl Alcohol.
-Used many MANY different chargers (Wall, Car, Docks, Firewire, etc etc)
And none of them have worked!! Any help guys?
