How do you put iphone back together - Apple iPhone (16 GB) Smartphone

This could be one of two issues:

1. The cable for the digitizer may have come loose them you put the iPhone back together.

2. The digitizer may be faulty.

put it in recovery mode (hold power and home button together for 5 sec), then keep holding just home button as it boots back up.
if that doesn't fix it, there might be a problem with your motherboard.
if you look for guides online for a screen replacement you will find something. I work for company that does iPHone repair in NYC and we do this repair frequently.

you destroyed your precious iphone why this may hurt but you need to go to an i phone store ask them to buy wats left and get a new one good luk

Do a search of youtube. There are lots of "how to" tutorials on how to do such things. Discovered this after having frustrations with what to do on my own 4S.

First try the easiest solution,
turn your phone off, take out battery,leave for about 5 min.
put back together, then turn back on.
If this does not fix your problem then it my have locked you out.
this download will unlock it for you.

Try This:
1. Remove Sim Card
2. Hold in 'Home' button and 'On/Off' button together until Apple logo appears
3. Replace Sim Card
4. Hold in 'Home' button and 'On/Off' button together until normal phone screen appears.


Also, Try this:
1.) Shut down the iPhone 3G.
2.) Start up iTunes
3.) Hold down HOME button on the iPhone 3G
4.) While keeping the HOME button depressed, plug in the Sync cable
5.) A message will pop up to ask if you want to reset.
6.) Just click YES and the reset process should start.

You most likely didn't connect a component to the board or one of the ribbon cables. I'd go back into the phone and follow the steps again to try and determine anything that wasn't connected as well as you'd thought.

Thanks

Put 3 fingers together on the screen and move them around, it should fix the problem. I somehow managed. The trick is NOT to put 3 fingers together whilst playing a game!!!!

Try a hard reset: Menu button plus power button together for 5 sec. If that doesn't work there is a motherboard problem. If Apple doesn't replace it for you, you can find the logic board on Ebay or at iPhone 3GS Repair and if you're tech savvy, there is a guide that shows you how to put in the part at iPhone Repair Guide.

Hold both the home and power button together for 10 seconds, it should at least give you an apple, if nothing then your iphone is gonna need some work...
