My Iphone 4s stuck on apple logo.I already connect it to Itunes on PC but it errors in restoring

Greetings JeromeDelta22,

Thanks for using the Apple Support Communities!

I understand that you are seeing the Apple logo on your iPhone and have been unable to restore it. In this situation, I recommend reading over and working through the steps from the following article to help resolve this issue.

If your device turns on but gets stuck during start up

You might see the Apple logo or a red or blue screen for a long time during start up. Try these steps:

1. Connect your device to a computer and open iTunes. If you don't have a computer, you can borrow one, or go to an Apple Retail Store or Apple Authorized Service Provider for help.
2. While your device is connected, force it to restart. Press and hold the Sleep/Wake and Home buttons at the same time. Don't release when you see the Apple logo. Keep holding until you see the Recovery mode screen.
   
3. When you get the option to restore or update, choose Update. iTunes will try to reinstall iOS without erasing your data.
   

iTunes will download the software for your device. If it takes more than 15 minutes, your device will exit recovery mode and you'll need to repeat steps 2 and 3 again.

If your iPhone, iPad, or iPod touch won't turn on - Apple Support

Have a great day!
