How to Update Galaxy Tab 2 7.0 GT-P3100 to Android 4.1.2 DDCNA3

If you’re in need of a way to update Galaxy Tab 2 7.0 GT-P3100 to the newest Android 4.1.2 Jelly Bean variant, you’re in luck. We have just what you want in the shape of this tutorial!

This Samsung device was released two years ago in April. The firmware we prepared for the upgrade came out last month. This means that your tablet’s OS will go from an older OS to the most recent version with the newest official firmware available. Its name: DDCNA3.

India is the country most suited for the firmware above. With an activated KIES logo, the new official firmware is indicated for people who want an
update done with KIES
. We recommend using this method only on a device which already has stock ROM on it.

If your Galaxy Tab 2 7.0 GT-P3100 isn’t equipped with stock ROM and you’re not used to the KIES option, you can use our tutorial. Which strongly advises you to update the Galaxy Tab 2 7.0 P3100 with our method instead of another tablet.

The novelties

The list of novelties delivered by the new OS are made of touch anticipation, a new keyboard and sync and connect email updates. If you think that’s all, read on: your tablet will sport Google Now, a fixed frame of 60 fps, mini apps and all share. But wait, the list isn’t over: extended Vsync timing, free style widget, automatic adjustment for the size of widgets and pop up play are also featured. The last two features: triple buffering and group cast.

Dealing with a rooted Galaxy Tab 2 7.0 GT-P3100 has its disadvantage. That’s because the update will do this to the root access and system partition: revoke the former and erase the latter. It’s not all black, though: the important data, internal and external SD cards will all stay where they currently are.galaxy-tab-2-P3100
