Default URGENT!

Hey guys I was recently trying to flash back to stock so that i could carrier unlock my device, but when I was trying to flash using cwm, I kept getting status 7 error, so I read up on that and learned that cwm doesn't like certain roms.
After reading that, I used twrp, which allowed the rom to flash.

Now's where it gets bad..

the rom was booting fine, until i realized it was stuck at the boot animation for about 10 minutes.
I went back to the thread and asked how long it should take on first boot, they said 4 mintues...

I can't get back into recovery mode.. (actually i could never get into recovery mode using hardware bottons, i had to use apps such as ROM Manager)
I'm trying to use odin to flash recovery img, but no dice..

Can someone please tell me what I should do?
