iPhone that freezes on the Apple logo can be a simple problem. It usually happens when you have just done things like updating your iOS, recovering copies from iDevices or posting a new app. To restore the device to normal mode again, there are some things you can do. You can either set the phone in Device Firmware Update (DFU) setting that completely restores your iPhone, or use Ifunbox to detect and delete problems that cause problems.
Using the DFU Mode
This method applies to almost all versions of the iPhone. First, with a USB cable, you need to connect your troubled Apple iPhone to iTunes. Then turn off the iPhone. Often it's not easy to turn off the iPhone that is locked and show Apple's tag. The trick to do this is to push both the home button and the power button for about 10 seconds. If you succeed, you must notice that the screen is dark. When the phone is switched on, continue to press the home button (while switching off the power key) for 10 seconds or longer to restore your phone to iTunes. The iPhone is now in DFU mode, then click OK and Restore options to restore the gadget to normal. It takes time and patience with this method; Sometimes you may need to repeat the process 2-3 times before you achieve the desired results. If you have already tried this method but have not been successful, you will probably need to turn off antivirus and firewall security measures and repeat the steps again.
Using ifunbox Software
The software ifunbox basically works in the same way that Windows File Explorer is user friendly. The software supports iOS 4.0 and has many features, including the ability to control the iPhone / iPod file system, video and music to and from iPhone and iPod, perform file operations on iPhone and serve as high speed general storage devices. If you have Ifunbox software, you can restore the problem without having to recover the phone. Basically, ifunbox allows you to see the applications you have installed on the iPhone. Simply connect iPhone to your computer and click on the search button to get a list of MY3G files. After the search results appear, delete all MY3G files you find and try restarting your gadget. Hopefully your problem will be solved now. Note that ifunbox is a light program you do not even need to install before using it. To prevent iPhone from happening again, only download and install applications from trusted sources.
