iPhone 4S turns on only with charger - no wifi, bt, mobile?
3 weeks ago I replaced the battery of my iPhone 4S 64G (2 years + 4 months old). Today it suddenly turned off but it will only turn on with the charger connected - after I unlocked the phone it does not regognize wifi, bluetooth nor mobile network - battery is at 100% but playing it little bit the display freezes.
When the charger is unplugged it will turn off completely.
Any clue which part of phone is broken? Its the logic board?
