This is a tricky one you need to open the phone. use a sucker place the sucker on the screen near to the home button. slowly pull up the screen slowly. when open up a bit you will see the screen connection etc carefully remove these.( take care of the hidden cable dont brake the flap that holds the cable in place just lift the black part from the bottom) and pull away the screen. now when this is done, take away the numbers cables in order it has them on it 123456 etc. and un screw the board. remove the sim card holder and lift from the bottom and pull out from the bottom at same time lifting up. now with board out clean the connections on the bottom of the board the copper squares etc a nail file pad will do. dont go to made doing it. then do the same to the others on the phone case. while the board is out get an old tooth brush and some nail varnish remover and put some on the tooth brush and clean out the connector for the usb and charger socket. and lave to dry. put phone back together in revers order. now when it is done plug into a pc/laptop not charger. it should turn on to charging leave to charge up fully. and phone should be fine.

My iphone wont turn on after dying


Try a hard reset on the iPhone. Basically all you need to do is hold down both the On/Off button at the top of the iPhone as well as the Home button (the physical round button at the bottom of the screen) for about 10-15 seconds or until you see the Apple logo on your screen. Once the Apple logo appears you can then release the buttons and let the iPhone turn itself back on again :)

Turn iphone off. Power on holding power and home at same time for 10 seconds, then release power button but hold home for another 30 seconds. Screen will stay blank but should be in DFU recovery mode. Plug into iTunes and recover.

IPhone 3Gs shut off and will not turn back on.


I just had the same problem but while filming a video and then pressing stop. You need to "cold boot" (hard reboot) by pressing the home button (center round one) and the start button (top right button) at the same time. Hold both buttons down until you see the apple logo on the screen. Your data should be there. Always go to an Apple Store if you have problems in the future.
