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;
  • create backups (a standard backup and a full NANDroid one, generated with this guide);
  • flash the sort of USB drivers which work for your tablet from this page on your laptop or comp;
  • charge your tablet’s battery if you notice that its charge levels are low;
  • download Odin tool v3.07. exe from this page and the Jelly Bean 4.2.2 T315XWUAMJ1 (the UK Vodafone version from here, the Spain Vodafone version from here, the Romania Cosmote version from this page, the Germany Vodafone version from here and the Austria T-Mobile version from this location on your laptop (or comp);
  • make sure you disable, on the notebook and the tablet, the security software that are flashed on them;
  • Windows must be the only OS running on the notebook or PC;Galaxy-Tab-3-8.0-SM-T315


  1. The first set of instructions looks like this: unzip the two packages that are now downloaded on your notebook, enter the device in Download Mode and then open the Odin on your laptop as an Admin; to boot the tablet in the Download Mode, do this: press and hold, simultaneously, these keys: Volume Down + Home + Power. That’s not all: the display will have an Android logo soon afterwards, so press Volume Up. That’s it.
  2. Once the Odin’s been launched, you should plug the tablet to the laptop with its USB cord. The connection between your devices will be established when a message saying “Added!!” and a yellow ID:COM box appear; when they don’t, you have to opt for the re-installation of the USB drivers or the use of a different USB port.
  3. If you don’t experience a failed connection between the tablet and the notebook, you can move on to these instructions: tap PDA, choose a file with CODE in the name, tap Phone, opt for a file with MODEM in the name, click on CSC, choose a file which has CSC in its name, tap PIT and choose a file with a .pit extension.
  4. A bunch of boxes will then pop up on the screen, so check them; here are their names: F. Reset Time, Auto Reboot and Re-partition.
  5. To see the Android 4.2.2 XWUAMJ1 official firmware flashed on the Galaxy Tab 3 8.0 LTE SM-T315, you have to tap “Start“. The end of the installation phase will be signaled by your tablet restarting and showing “Pass” on the screen. Unplug the gadget from your laptop: the stock firmware is now flashed on your device. Its location is your gadget’s About Tablet.

If you have doubts about this new firmware, you should revoke the update process by using the NANDroid backup file. By revoking the upgrade, your tablet’s old ROM is going to be restored.
