Lets say I don't do S-Off (i don't really know what that is, my earlier phone was a crappy samsung) and I do the update with the RUU, will I be able to do S-Off later???
The thing is that i don't want to void the warranty. Coming from a really bad phone, where I had to mod EVERYTHING to get it working acceptably, I would really like to settle down and be stock for a while. Of course, that feeling will probably last a few months and then I will be flashing roms every 2 days lol.
If I flash the RUU manually, that doesn't void the warranty right? I mean, its an official firmware i suppose. On the other hand, if I can only do the S-Off thing right now, i might consider staying a while longer with 4.1.2 ... after all it is not so bad.
