iPhone 4s

[blissgirl]

Hi Guys wondered if you can help me this morning my old iPhone4s switched itself off and won't turn back on tried to plug into computer but nothing any ideas?

First off try holding down the power and the home button for 10 seconds to see if the Apple logo appears and then release.

It is fully charged yes?

If that doesn't work you need to try DFU mode but try the above first.

@jonsie i charged it last night and this morning it was working fine
