General Upgrade from Jelly Bean to Kitkat

Hi
I have just bought Samsung Galaxy Young GT-S6312. It came with Android Jelly Bean (4.1.2). I want to upgrade it to Android Kitkat (4.4). I know the procedure of upgrading android OS, however, I have two questions:
1. For this phone model, which android rom should I use, as in YouTube comments, some people are complaining that after upgrade their phone stuck at boot, and I want to avoid this error.
2. In case this happens, then how can I revert my phone to factory OS, where I can download this factory OS and how can I restore it?
Regards
