. Thank you!
fghjrxzd, what's your current Android Version? If you're NOT on lollipop, you can try some automated apps which will give you Super User permissions such as the app mentioned by z0ne.
Thank you for your valuable information. that kingroot something. will I just download it at my phone then open and let it do the miracle?. after rooting what would be the best steps or apps to do/download?
After rooting you'll need "SuperSu"or a similar app to manage root permissions. If you want to cheat on games you can use SB game hacker or Lucky Patcher
Well, I'm used to NOT suggest you to install a Custom ROM if you're not experienced enough. Also, you have got very good chances the official rom of your device should be good enough to grant long life to your device, especially if your device isn't popular enough to attract expert custom-roms developers.
Anyway if you really want to install a custom rom to your device, maybe the following link could help you:

Please note, it's the most stable ROM I found for your Android device but please note there are few bugs.
I'd rather suggest you to customize your official rom, changing its appearence. There are lots of apps on Google Play to customize it.
This way it'll be 100% safe and hopefully without any bugs!
Since your username is very hard to mention and to read, I could change it for free, if you want. Just tell me the new username you'd like and I'll think about it.
