So here's the deal. I had Cyanogenmod 10.2 on my phone for a while now and I've always had problems, although a nice rom but too many crashes, battery drainage etc. So I wanted to go to stock but before doing so I thought I'd give Cyanogenmod 11 a try and see how that works, which turns out to be worse and I lost all phone signal and data, pretty much no service. So now I tried to go back to stock for good. I downloaded the stock 4.1 something rom file, odin and tried going back which didn't work cause I would keep getting a fail sign on odin. By the way I tried different versions of Odin since that was suggested to me by my friend and that didn't do anything either. Then I read a blog about using Samsung Kies on my PC, now after I did that I got a message on kies that my phone encountered an error. Now when I turn my phone on I get a message "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again."
Is my phone bricked for good? Can I go back to stock? I'm not sure what else to do here now. Why is it hard finding a stock unrooted 4.3 rom for my phone on the internet? I also can't use that clockwork recovery mode either, it just gives me the message "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again" when I try going into that to even try and install Cyanogenmod again so I can use my phone until I find a solution to going back to stock.
Edit: Ok so I just installed clockworkmod recovery through odin and I was able to install a rooted stock rom through the recovery, but now the problem I'm encountering is that it gets stuck on the AT&T logo when booting up the phone. Installing stock rom through odin still gives me the fail message.
Edit 2: I tried installing a stock unrooted rom through recovery and it gave me some error but now the phone goes passed the AT&T logo after that however I have no service now. How do I fix that and how should I go about installing stock unrooted rom since Odin gives me the fail message?
