I want to ask about w300i

" Weather security camera my asking wires ".

Well I read it 8 times and still no clue. Why do you have a security camera for looking at the weather? Why is the camera asking you for wires?

Green is normally Ground, but may depend on the make and model.

you have to press and hold the button on the jabra for a few seconds till it either stays lit or flashes, then search for it on your phone, then when it asks enter the passcode (if it asks for one)
As you dont mention what version of jabra you have i cant help with the code, consult the user manual

it is not possible as the space in sim is only 32 or 64 k and can only same contacts and afew msg.

Have you checked for the battery?

It might need replacement.

Hai dud,
It appears the so-called WSOD affects several models of SonyEricssons, and there's nothing that can be done about it, at least from the consumer's end. All you can do is call up SE, tell them the problem, and they may (should!) issue an RMA. 

Hope it Helped You!

it can be defactive battery problem. did u try by changing new battery.
if not, do it by the way.
or if it not the issue then tell me that this problem comes automatically or when u open its flip to get viewed inside.

The flex cable is damaged, it needs to be replaced. It is what connects the motherboard to the lcd screen in your phone. I had to replace one not to long ago and it had the same problem and now it works. Hope this helps. Good Luck!!!!!
