Problem with 3gs 4.2.1 DB 06.15

[balar]

I have problem with my 3gs i update the software to 4.2.1 and JB with update DB to 6.15.
Now my iphone is recovery mode and i can't exit!
I try recovery with original software and i have error 1015, next i try this method:

Step 1: reinstall the 4.1.2 Original firmware on to your Iphone and you will get the 1015 error (Which is normal)

Step 2: Open redsnow and choose the Original 4.2.1 firmware and after verifying click on enter pwnd DFU mode then do the process.

Step 3. open back up itunes and point to the Custom firmware and let it install. You will not get any errors but the phone will go back to recover loop. PLEASE LISTEN WHEN I SAY THIS YOU CAN USE TINY UMBRELLA OR ANY OTHER EXIT RECOVERY PROGRAMS IT WILL NOT WORK. So please save your time and do the method im going to explain

But do this carefully.
Unplug the phone when it is still on the recovery screen. hold the power button until it turns off. Then turn it back on and you will get the apple logo wait for a bit and you will see the bar under it and you will get back to the emergency screen.

If you need files let me know right now i only have the 3gs files thank you

After flashing Custom firmware i don't have Recowery mode i have DFU mode and i can't exit it

Anny suggestion how alive my iphone??
