Broken Logic Board Battery Connector

Hi all

I wonder if anyone can give me some advice before I do the repair?

I have an old iphone 4 with a broken battery connector. When connected to the mains the phone starts up as normal but has a blue banner on my old home screen picture stating activation required. When i slide to unlock I get the connect to itunes screen.

When I connect to the laptop all I get is a the apple logo cycle. Since I connected this phone I realised there are some pics there that I don't have which weren't backed up.

Is this issue just down to the missing battery connector.

Thanks in anticipation

Jonny
