Iphone 4

Hi All

Can anyone help with a Iphone problem? I replaced the internal battery on a Iphone 4 s and it has been working fine, The person i did this for has now dropped the phone and it will not switch back on it just flashes the apple sign every ten seconds, As its been dropped I think its unrelated to the battery but has anyone got any advice before I open it up tonight to take a look please ?

Thanks
Ash

I agree that it is unrelated to the battery, as it was working when you replaced the battery and dropping has caused the flashing. The fact that the phone is displaying the apple logo indicates that the battery is still supplying power.
You could check for unseated connectors on the logic board, disconnect and reconnect them, since the drop has probably shifted one of them.

Hi Mickster
Thanks for the reply, Yes I took the back off and had a look last night as far as i can see everything is in place, I even took out the battery and reconnected it again, I have tried system restore and update but they will not go through, On further looking I think the charging dock is damaged

At the university I had a long line of girl friends with broken electronics. (very shallow relationships) They were only after one thing.
Got a wife and thought I now have only one person who needs electronics fixed. But she has a long line of friends.
