Can anybody help me please, since i have updated my iphone 4s to OS 7.1.2 it is no longer recognised by itunes and computer, also it will no longer charge while it is switched on. ( But it will charge while it is switched of. )
If you are using a Windows based computer, follow the instructions for resetting the AMDS > How to restart the Apple Mobile Device Service (AMDS) on Windows
Reset the AMDS then see if the battery will charge while the iPhone is on.
If not, try a reset.
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
If that doesn't help, tap Settings > General > Reset > Reset All Settings
No data is lost due to a reset.
Thank you for your help Carolyn, i have try'd everything that you have suggested and nothing have work. but a message does come up on my Computer saying the following.
