Can you make sure the battery connector isnt damage at all? The shutting down thing sounds like a battery problem. The white screen sounds like an LCD problem. If you have the old screen, try putting that in to see if it does the same thing. Report back with what you find.

Hmm, check if the connector on the battery has any tears, this looks like it is/was receiving power then it just doesn't. If you can get your hands on another battery, then try and test it that way. Looks like a power issue rather than an LCD issue.

I have tried this, used another battery but still the same problem.

yesterday i tried to turn it on and use it with my sim-card and it was on for like 1 hour!

So it was on for like an hour with another battery?

No, with the same battery. When i put in another battery it also doesn't work.

Just open it up and check all connections.

Especially the battery and the logic board connections.

The way the screen gets that white haze definitely shows a problem with the display. Is the phone definitely turning off, or just the screen losing picture? Have you tried calling it after its crashed?

May just be a faulty display.

If it is definitely turning off then I would certainly say it needs a new battery.

Changing the sim card wouldnt change anything.
