The first Jelly Bean update came to the Galaxy Tab 2 7.0 WiFi GT-P3110 back in December when the device received Android 4.1.1. It has been about 3 months since then. And now Samsung has been rolling out the latest version of Jelly Bean, that is Android 4.1.2, for its devices. If you have this second generation tablet device, you can avail the Android 4.1.2 OTA update by checking for its availability for you country region. Open Settings> About on your Tab 2 and tap on Software Update. You can also keep an eye on Kies for the update notification.
The Android 4.1.2 update is rolling out in phases and is currently available for select countries and regions. Nevertheless, it will hit all remaining countries soon so you will have to wait patiently. Note that if you have rooted your Galaxy Tab 2 7.0 P3110, you will not be able to get the OTA update. In that case you will have to update your device manually.

You can install any unbranded firmware from below. Only make sure that your tab’s model number is the same and also that it is not network locked.
