You can only do so if you have iOS 4.3.3 SHSH blobs saved for your device specifically. Check to see whether you have them first.

how to check iOS 4.3.3 SHSH blobs are available for my device or not ??

 

[willerz2]

Open up Cydia. On the main page, scroll down to the TSS Center and see what iOS's are listed at the top.

I will try make it as simple as i can...

• Don't use the SHSH blobs from the cydia server, it will cause error, use only those available in your [FONT=Droid Sans, sans-serif]device.
  [/FONT]
• [FONT=Droid Sans, sans-serif][/FONT]Use TinyUmbrella to backup your SHSH blobs ( always uncheck Request SHSH From Cydia)
  

Since you don't have the SHSH blobs from your device (not the cydia one) , the best bet is to restore the iOS 4.1 firmware.

• Download the iOS 4.1 ipsw for your device & restore it through redsn0w. The device will boot up.
• If you want to upgrade, save the SHSH blobs using TinyUmbrella & restore the new firmware through redsn0w.

There are lots of methods, but i think this is the safest bet....

Follow this procedure

Go to DFU mode, use the official ios 4.3 ipsw (not the custom ipsw you made) , restore the device through redsn0w (not through itunes)

When redsn0w asks for SHSH blobs, select local and use the 4.3 one you saved using tinyumbrella (make sure the blobs are from the device & not from the cydia server)
