How to Update Galaxy Tab 3 8.0 LTE SM-T315 to Android 4.2.2 XWUAMJ1

Galaxy Tab 3 8.0 LTE SM-T315 happens to be the tablet that will receive, today, Android 4.2.2. The help this time around comes from XWUAMJ1, which is official firmware created for this gadget.

The Galaxy Tab 3 8.0 T315 was officially launched this year in July. The new firmware came out in October and was thought for the following regions: the UK (Vodafone), Spain (Vodafone), Romania (Cosmote), Germany (Vodafone) and Austria (T-Mobile). The only version that comes with a KIES logo that’s not activated is the one meant for Romania; this being said, you can’t update your tablet with Samsung’s KIES. You can do that for all the other versions, though. Or you can use OTA via the Software Update button located under Settings menu in case you want.

But if you go with our guide, we guarantee the following new features for your tablet: a new Gallery app delivering superior speed when loading, the possibility to long-press the WiFi and Bluetooth icons in Quick Settings to be able to toggle the on/off state, new sounds for wireless charging and low battery bug fixes, fixed Bluetooth audio streaming bugs, new download notifications and USB debug white-list.

This variety of new features will only end up on the Samsung SM-T315 provided that the gadget is running a custom ROM. Don’t update a different tablet model with our tutorial, you will only brick it. If your device has root access, it won’t have that anymore once the tablet’s been upgraded. The important data will be saved, but the system partition will suffer. The internal and external SD cards will also be fine.

Requirements are now in order, so look at the list below and do what we instruct you to in it:

  • your tablet must have USB Debugging enabled;
