Pardon me for asking, but I would like some help with my Galaxy S3. A friend helped me root it a few years ago when I first got it, but I don't keep in touch with him anymore and I don't know how to update its firmware now.
I know it's rooted for sure as I've got SuperSU and Titanium Backup installed on it, but I've been on Android 4.1.2 for years now because I can't update it normally anymore. Everytime I look into trying to do so, I'm confused as to which method or files I should use, so I would really appreciate some help here.
Just a couple of queries first.
1) Is it possible to just update the firmware without any fancy ROM or anything like that?
2) Will I lose my data from doing so?
Again, please bear with me as I'm really new to all this and I might get some terms or understanding wrong. Thanks in advance.
