apple logo flash then black, backlit screen
Ok so, itried fixing a water damaged iphone 5s today and did the whole alcohol thing. so i put the motherboard in and tried turning it on... nothing. so i plug it in then i get an apple logo for about half a second then it switches to a black backlit screen and stays there. maybe i didnt remove all the corosion and need to clean it more? by the way i did plug it and itunes recognizes it and i restore it... i get an error code 3194. right now i am stuck and have no clue what to do because i spent a lot of money for the parts. I know the parts are 100% working because i tested them on a different motherboard. also lastly my phone doesnt turn on unless its plugged in.
Is dit een goede vraag?
