Phone doesnt power on.
Hello! I bought few phones for really good price, in the bulk was a lot of batteries i tried them all on the phone but only once the iPhone connected to PC in DFU And was charging, before i managed to download the software the phone disconnected and never connected to the PC again. i cant tell if the phone is showing something on the screen because i dont know if the screen works. Weirdly the same thing happend to iPhone 6 Plus that was in the bulk connected once and never again. I even tried all the batteries on the other 6 and 6s Pluses, but nothing happend. Is it the battery? im not sure if its worth to get a battery and test it or could it be something else wrong? I dont even know if the screens are working ..
Is dit een goede vraag?
