Well this is what I did,
I tried to update from 4.1 to 4.3.3 using a custom firmware. I used SnowBreeze 2.7 for extracting the firmware and had Tiny Umbrella running to avoid errors plus used ireb to put my device into pwned dfu mode also to avoid errors.
Everything went fine until the process was all done and itunes said that your device will reboot and will show the Iphone Icon. But whenever i try to turn it on itunes detects my phone in recovery mode!!!....Any fixes for that
P.S : My baseband is 6.15.00
ANY SOLUTIONS?????
