first of all i am a noob at this kind of things but i really wanted to try out the 4.3 android.
while i asked some people and told me to flash via odin as the previous firmwares, it stuck? i dont know what happened, and now my phone says
"Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again"
The only thing that is working is the Volume Down+Home+Power button to get to the download mode, there it says :
KNOX WARRANTY VOID:1
AP SWREV: A2
i dont know what these are and i know i shouldn't have done something like this because i am a noob and now i am paying for my mistakes, i beg you help me my phone doesnt even start.
One more thing, i read to flash the stock firmware via odin but i tried it and it stuck at NAND write start, nothing happens after that.
I am so sorry for being totally useless but i need desperately your help,
