iPhone 4 keep rebooting after screen replacement

I have a big problem, i replace my broken screen and now my iPhone 4 don't have signal (no service) AND keeps rebooting after 2 minutes.

2 things: i can't "reconect" the lower antenna connector to the logic board (dont fit in the socket) (image)

and i dont turn off mi iphone when i was changing the battery the first time (i read that this could be the problem) also my clock restart to 1969.

thanks for the help and sorry for my bad english.

We can't see the picture. The date/time thing is just a small ios 6 bug.

You biggest problem is you cant connect the antenna connector. As long as you dont fix that the problem wil be the same.

The rebooting could be a battery problem, or just software. Did you try restore?

I had the same issue it would not boot, just keep restarting its self, just display apple sign then 5 sec later just turn off....

I dont know if it was because of shier luck but here is what i did

Plugged phone into PC, Apple sign appeared

Removed phone from pc then Held Power on for 3 secs

While holding power button held Home button in for 10 secs

Then release power button still holding in home for 10 secs more..

then phone turned on and stayed on.... i have signal and all functions seem to be working fine... hope this helps someone out there
