Ok, i found the fuse....
it was shorted.
but i killed the phone by heating the shield to remove it...
i relised this: DONT heat the shield to remove it, break it off with fine screw driver.

When You Plugged Charger in it U5(NCP345) Will Enable U4(P-Mosfet) For Cgarfing If VCHG1 Pin5 Rhan 6.8 Volts. The Precess Restat If Batt VHigher Then 3.4. Pre Charger Crrunt Is Abt 40mA Depands On VBattry...

When ICHG is Larger then 1A The Pt1 Will Opand (OCP)

Also Remember If Battry CVoltage Above Then 4.35v U104 Will stop Charging....!!!!
