Error- 21

Hello friends,

This is my first blog.
After spending 2 years +, I thought of writing my blog for people who face lot of problems regarding their respective iOS devices.Various errors and many more are part of iOS devices.

In my first blog I'll be covering up with error 21which is common error  now a days for people updating their devices to iOS 6.0.1
(Specifically for iPhone)

So
First your device must be stuck in recovery mode
Download the latest version of redsn0w from Dev team's site.
After opening it
Click on Extras
Even More
Restore- Choose iOS 6.0.1 for your respective iOS device.
Redsn0w will ask for baseband preservation entering into dfu mode.
Put your iOS device in dfu mode n proceed further.
Redsn0w will do its work.
Now important thing to notice. When the whole process is done at the time your iOS device is booting, check whether its stuck on recovery mode or not.
Two options:
1- Use redsn0w's recovery fix to get your device out of recovery mode.
2- The second option which I prefer is that open iTunes, Press shift+restore and point your respective iOS firmware and let iTines work its magic.

Voillaaa after this you have successfully updated your device to iOS 6.0.1.
(Specifically for iPhone)
