Samsungs are generally flashed with new ROMs in the same way, use ODIN to flash TWRP, backup the existing ROM with TWRP, flash new ROM and Gapps with TWRP. Since some of these steps are device specific, best to ask in the forums for your specific device as to the best current methods and versions of software.
Unless you can ask a more specific question, the scope of this general question is beyond a simple answer.
You just need to flash a brand new firmware on the phone. I found two versions for your phone with different plateform - One on Qualcomm MSM (MSM8625Q Snapdragon 200) and the other on MTK (MT6572). Since you've provide no clear description, I'll post two solutions as well.
- For MSM plateform, you'll need Odin (Heindall if your computer runs Mac OS) to flash your phone: Go here and download the firmware and follow the instructions on how to flash.
- For MTK platefore (also cloned phone), you'll need a flasher called SP Flashtool and a flashable ROM. Look here.
- For custom ROM (to upgrade to a hi version of Android OS, e.g. Android 5.0, go here and follow instructions carefully.
There is no way to change the OS If you are using a Samsung phone in recent years Then it is most likely running android You could root it but i will NOT recommend it as it will lead to unforeseen circumstances. To solve your problem you could try deleting some files and Apps that you do not use.
