I currently just had my uncle hand me a Samsung Galaxy Note 2 GT-N7100. At first I had to service it so that it can read my SIM card because it was locked to a previous provider (It was locked to Smart. I'm from the Philippines). I paid him quite cheaper compared to the others that I talked to so I think he used an easier method by just rooting my phone. I checked and it is rooted. My question is now, can I still update my firmware to the latest available for this model? My current version is 4.1.2
Thank you for any help that I'll get about this. Open to suggestions as well to remedy.
