Make backup of stock rom without ROOT
Friends our cwm is working without root also..so backup your stock ROM without root from cwm .
If you backup your rom from cwm then you dont have to go for odin every time for reflash your stock rom.
Just whenever you flash any custom rom then first go for restore stock rom then root and then flash any custom rom..
Then your mobile never brick..
Always go to stock rom then flash custom rom..
Sorry for my english.
