Stuck at recovery mode

[tapansheth]

hi

please do help me.

i tried to update my phone with 4.2.1 and after updating it I tried to unlock it with redsn0w and now it stuck at recovery mode.

I tried to restore via itune it gives me error 1015.

I also tried with custom firmware I found for 4.2.1 and tried to restore with itune and I got error 21.

Now I am stuck at recovery mode.

Please do help me.

I don't have custom firmware. Can anyone guide me from where can I get custom firmware to update my phone.

Please do help. PLEASE
