I have recently purchased a galaxy s4 from tmobile. It came with Android 4.3 and is the m919 model. I was trying to make a back up before putting cynagenmod on my phone and somehow jacked up my firmware
. Now It won't boot and just goes to the screen saying the firmware has been corrupted. I was looking for the stock os to put back on it before I try again. I have nothing on the phone and don't care as long as I can get it back up and running. I tried to download what I think is the stock rom from samsung updates but only the rapidgator is available and that said 16 hours when I started it yesterday at 7. Now its 6 the next day and still says 14 hours. Anyone have any advice or a link to the stock rom? I don't even care about the stock as I just want to put cynagenmod on it. Can I do that without putting the stock on? Thanks for any and all help.
