Im a noob when it comes to android. I would be very grateful if anyone could assist me in upgrading to the latest firmware. I have a Samsung tab (GT-P3100) i bought from the UK and it is unlocked. Can i install any latest firmware from any build number, or do i have to use the firmware specific for that tablet. The latest version of android installed is still 4.03 while firmware from other countries are at 4.2.2.

Some info on the tablet:
