Hi There

After a drop on the floor, my Iphone 4 IOS 6.1.6, NO physical damage, NO Insurance, NOT hacked and NOT jailbroken, is stuck in this cycle, i keep getting the apple logo and a black screen.

Things noticed while connected to PC
- Phone is not recognices by PC / ITunes
- Restarts over, but only until the Apple logo is shown

Things noticed while connected to wall socket
- Phone starts up
- I can insert pin
- I can work the Iphone for some time (about 1 Minute)
- No carried and no WLAN will be found
- Speaker does not work
- Vibration works
- In the setup, carrier line is not shown and WLAN is grey (can not manipulate)

- Then after a minute it shuts down and restarts

Other things noticed
- Without power, the phone is black
- Can not enter into DFU Mode
- From the inside (completely opened) the phone looks ok and all connectors sit well and the connector cables seem to be good
- After reassembly, same function as stted above

Can anyone help me with this??? Recommend on what to do or what to replace, other than the Phone, haha

Many thanks

If you're feeling adventurous, I'd pull it all apart, and reassemble it, just to make sure everything is connected.

Something I've encountered in the past: a drop can tear a cable or disconnect a cable from the logic board.

My friend's iPhone 3GS stopped working when dropped. Something with the battery was damaged, possibly the cable. Replacing the battery fixed it.

A relative dropped her iPhone 4 and the screen went black. The cable disconnected from the logic board. Opening the device and reconnecting the display cable got it working again.

Also, iOS 6.1.6 was never released for the iPhone 4.

iOS 7.1 is the current version for it.
