chinese nokia N97 can't power on
 

I have one chinese Nokia N97 which can't power up.When i press power button it just blinks with this note 'flight mode?' and you have options 'yes' or 'no',but that stays on the screen just for a second,and turns off. If I connect it on charger nokia logo appears and freeze on that,while the battery is charging.If i try to power on when it's on charger again the same,flight mode screen for a second and turns off.

anybody to advice me something,or give me a pinout and flash directions for infinity box?????
under the battery writes: N97 RM-159, if that means something.

thanx in advance!

I have the same problem. Anybody help?
