iPhone 5 Restarts 2 second after pressing the on button
I have an iPhone 5 that once i have pressed the on button the apple logo comes on the screen for 2 seconds then fades out and the phone reboots. it will continue to do this until i turn the phone off.
If i am quick with my timing i can get the phone into DFU mode and iTunes will detect it and start the recovery process, but as soon as the phone restarts and comes out of DFU mode the boot cycle starts again and iTunes eventually gives error 4005.
i have opened the phone and can not see anything that looks out of place. Does anyone have any tips to get this phone to boot??
Thank you in advance
