I have the t-mobile US t999.
Last night I was having an odd issue with the networking dropping. I've had the phone for about a month, modded since day 1 with a CM10 variation of a rom (sorry, I forget the exact rom). I had no issues whatsoever up until this point. After a few restarts thinking maybe it was a fluke issue with the network, or network signal in my room, the phone forced itself into emergency call mode only. I couldn't get it to come out.
So I decided I was going to odin on a stock rom as I could get it into download mode, that went through successfully. When the phone boots, I get the android taking off (Tmobile 4g) logo. Then the white samsung logo, and it doesn't go beyond this. I know this can take long so I left it there for about an hour, nothing. The phone also displays a blue led the entire time it's hanging as well.
Also worth noting, when I attempt to boot into recovery it just vibrates over and over.
Not sure what my next steps should be. Any help would be greatly appreciated.
