Features not working. ROM help

[FAM0X]

Ok, so i bought a use samsung galaxy s3 I747M. When i got home I was excited to test out all the cool features advertised in the comercials, to my horror, none of them worked. palm screenshot, video while texting, and i cant find the driving mode or s-voice. After tearing through all the settings, I found the the previous owner replaced touchwiz with cyanogenMod 10. Is this why these features dont work? If so, can someone please give me a step by step manual on how to get touchwiz back? keep in mind in super noob so i wont understand your techy lingo lol. Appreciate it.

That is the problem. He has updated the phone to a Jelly Bean ROM. Do you know if the original owner created a backup of the original ROM (Ice Cream Sandwhich)? If not, what network are you on?

No, i dont think he did. I am on Rodgers. Anything I can do?

You should be able to find a stock ROM for it. However, be careful as not all S3's are alike. You will need one that is compatible with your handset and Rogers.

Also, make sure that you really have a good understanding of how to do this. If you are not careful, you can destroy your phone.
