I downloaded 4.1.1 from here: http://www.sammobile.com/firmwares/1...e=TLS#firmware.. why is it keep on failing? i have checked and kies is off and i am using the original samsung cable odin recognizes the phone but it "fails"
Be thankful Odin failed because if it hadn't you probably would have had a bricked phone on your hands now. Like the senior member already advised, you can't downgrade the bootloader on the 4.3 to an older system. Desktop Odin tries to flash most partitions which is why it failed. If I may ask, why are you trying to downgrade to 4.1.1? If it's to free unlock the phone, you may be advised that there haven't been conclusive results on the viability of this process. It's possible to downgrade the system itself without downgrading the bootloader by flashing with other methods apart from Odin. I'm not aware, however, that anyone's been able to unlock even after this.
It's unlikely you'd be able to use Kies to recover from the phone's current situation as Kies will likely try to update to 4.1.1. If it isn't booting or working normally, you may try doing a hard wipe from recovery. If your phone still has warranty left on it, you may try an authorized service center. I am also assuming you are using an AT&T phone? You may be able to get it fixed at Best Buy
