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 or the iPhone won’t turn on wiki for more 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...

The issue that iPhone won’t turn on may be caused by hardware issue or software issue. If it is the hardware issue that causes such an issue, please go to the Apple store to repair it. If not, try using iTunes to restore the iPhone or apply a repair program like Joyoshare UltFix iOS system recovery, 3u Tools, and the like. Such programs can fix various iOS issues with no data loss.
