[QUOTE=ya_sin90;138413]I've a pair of w850, white and black..
there's no problem with the white one when i want to connect it by XS++..
but when I connect the black one, here's the result..
can anybody tell me what's going on with this phone? and what should i do?

Check this :
1. make sure your bateray is full
2. see the red led inside the power button, does it blinking ?? ( when you powering the phone )
If so , repair gdfs
3. Chek the charging port on phone, sometimes it's getting dirty and make bad connection. So clean it up
4. Try to hold 2 and 5 in the same time, while you connecting DCU 60. Does it make any different respons ?
5. If there is no different respons , you must check inside your phone.
- check flexicable or ui board or replace them

Hope it helped. Sorry for my bad english
