As the title says, I will teach you how to put an iPhone in Recovery mode.
Step 1
Disconnect the phone from the computer if you have it connected and open iTunes.
Step 2
Turn off the phone by holding down the Sleep/Wake button until the message appears asking you if you want to turn off the phone, then slide to turn it off.
Step 3
After the phone turns off, wait 5 seconds then press the Home button and keep it pressed while inserting the USB cable into the phone until the image with the USB cable below and the iTunes logo along with the message of warning.
This image should appear on the phone screen.
Step 4
If following this tutorial your phone screen displays that image and you are sure you know what you are doing, you can start the restore process.
If you encounter other problems that are not covered by this tutorial, please ask me using the support page located here.
