johhny tran, what happened to the phone? Any damage that you know off? Any water exposure? Any recent updates to the phone? Did you ever have it working or did you get it in this condition?

I dropped my iphone 4 and now it will not come on. i held the power button for 30sec. I tried plugging it in. It will not turn on. At first you could here a noise. Now nothing it's black.

I double-clicked the back button on the web browser and it froze. Naturally, I tried to press home and exit the browser. After this failed, it turned it off. It now will not turn on again. I tried alot of tricks from things I found online and it still won't turn off. I hope its not broken!

First, try connecting the iPhone to a wall charger to see if it will turn on, which will begin to happen immediately. If that does not work, let it charge for 10-20 minutes and hopefully it will turn on.

Second, try a Hard Reset by holding both the Power/Top button and Home Button for about 15 seconds until iPhone turns on.

Third, try carefully cleaning the charging port with isopropyl alcohol. Make sure to clean the charging pins and let dry for a few minutes. Then try to plug in a charger and turn on iPhone.

If these initial attempts do not work, check out the iPhone 4 Troubleshooting Page. for more troubleshooting solutions. Good luck.

put into DFU mode.

1)plug in your iphone

2)hold the power button for 2-3 seconds.

3)still holding the power button, hold the home button for 8 seconds.

4)let go of the power button, then still hold the home button for 8 more seconds.

5)reverse the steps and this may take a few minutes to reboot. if this doesn't work restart the steps.

(ps. he does not say step number 2 but i find it works better.)http://www.youtube.com/watch?v=34v8HMC9B...

My iPhone is on but the screen won't come on. I've plugged it in and you can hear the sound an iPhone 4 makes whenever it gets plugged in to charge. I locked my screen with the square thingy on the screen whenever it was unlocked & that's when it started .. It was frozen so I couldn't do anything. What's a tip ?

usually this means the battery connector disconnected, crack it open, unplug the battery, and plug it back in.

I dropped my iphone four on the floor. it was in a case with the back of my screen cracked already beforehand. My home button does not work so I am not able to turn it on using the power and home screen button. I believed the back had come loose but everything is still in tact. Any suggestions?
