After more than a month of waiting for Android 4.2.2 I decided to go for it, and try the alternate route. I downloaded a Generic ES (Spanish) 4.2.2 ROM (read here), and flashed it to my phone. The downloading of the image and installing the flashtool are the timeconsuming tasks, flashing the ROM is a piece of cake. Be sure to not wipe the data and cache partition (untick 2 of the 3 checkboxes) if you want to retain what’s on your phone.
With the new Android I would be easy to acquire root, so DoomLord said. No unlocked bootloader or whatsoever needed. So I downloaded his tool, did what the screen said, and less than five minutes later I had a rooted-phone. Things couldn’t be easier than this.
