Connect your iphone to the computer and open itunes. 

 

say you put in dfu mode, no? 

 

because when in dfu mode in itunes have a tab that says restore the iphone, the prick and wait. 

 

Greetings. 

 

PD. DFU Mode 

 

1 connect the iphone to the computer with itunes open. 

2nd off iphone 

3rd keep the two buttons pressed for 10 seconds 

4th after exactly 10 seconds, release the button above and still pressing home button 

 

Appear a sign on itunes saying it found an iPhone in recovery mode.

The error 21 and error 1602 are products that itunes does not connect to apple servers to verify the firmware, so it is faster if you can try it on another computer but I spent a tutorial about it. you'll say.
