and i didn't use battery gnd as -, i use one from round pinouts, and when try to charge phone it shows message "charging" as i said in post before.
and another interesting thing: when the charger is disconnected from wall the battery animation is still on, like it is on charge, but when micro usb connector is disconnected from phone then message came up to take out charger from power source
as i said before that this way is my only option to make charging and usb connection because i don't have so thin pin for soldering.

edit: i found on n900 schematic that +5v on usb pin is actually vbus, or how i find on cpkb.org usb power detector. so, if i connect the wire to the pinout that is described as vbus or usb power detector, does it means that it is the same thing as on the origginal usb connection?

here is the picture of schematics
