If your iPhone gets to the Silver logo but restarts from there again and again then it is an indication of problem with the booting system. This often results due to Jailbreaking or updating your iPhone to latest iOS without enough battery life. You can fix this easily by entering into DFU Mode.
A DFU mode stand for Device Firmware Update mode which helps you to make small changes to the software that is exactly responsible for running your device. It is most often confused with Recovery Mode but it is very comprehensive than that. To enter into DFU mode follow these steps
Step1: Connect your iPhone with Computer
Step2: Since your device is turned off you need to hold down the sleep/power and Home buttons at the same time for atleast 10 seconds. Be patient in this step and make sure you hold these buttons for exactly 10 seconds because otherwise you will enter into recovery mode.
Step 3: After 10 seconds have passed, let go of the sleep/power button, but keep holding the Home Button.
Step4: Now Apple Logo will appear on you iPhone but you should not stop holding the home button until recovery warning pops up on your iTunes.
Step 5: A difference between DFU and recovery mode can understood by observing your iPhone screen. If it is black then you are in DFU mode and if shows a cable connecting to the iTunes icon then you are in recovery mode. The latter cases you will need to repeat all the steps and this time you should lay more emphasis on Step 3 and Step 4. It is normal if you don't get there in first few tries.
Once you are in DFU mode you can downgrade your iPhone iOS in case the new version has created the problem.
