[Q] Information Overload, please help a noob
Hi, I just got an i9300 used at a great price, but after some reading I'm overwhelmed at the amount of guides for it and information. Right now it's on the official stock ROM (latest firmware). I want to restore it to factory settings (it still has some of the previous owner's customizations), and root it so I can remove the useless apps like ChatON.
If I'm using Kies and Odin, would I need to back up the EFS data? Also, if I root, I would have to flash again via Odin? Is there any possibility of devices becoming bricked due to using Odin?
I just want to use the stock ROM with root.
I'm upgrading from an Xperia U, but this phone seems a lot more complicated. With the U I could use flashtool without a care.
I appreciate any help I can get.
