Instructions

  1. Moving on, we will show you the steps that your tablet must go through if you want it updated as soon as possible. Download, on your notebook or computer, these files: Odin tool from here and the Jelly Bean 4.2.2 XWUAMH1 stock firmware (file name: INU-T311XWUAMH1-20130913100405.zip). Then don’t move on until both files’ content is extracted on the notebook or PC you’re using.
  2. Then be sure to launch the Odin on the laptop and switch the Galaxy Tab 3 8.0 T311 off since you will need to make it reach Download Mode by pressing + holding Power + Volume Down + Home at the same time. After the tablet boots into that mode, you should plug it to your notebook.
  3. The connection is going to go well if the Odin recognizes your tablet. And it will recognize it by displaying “Added!!” and a yellow ID:COM box.
  4. When none of the signs before show up, you have to try again, but this time install the USB drivers a second time or take the USB cable and use another USB port this time for it. As soon as one of these solution works, you can go to Odin, tap PDA and then opt for the new firmware.
  5. Leave the boxes dubbed F. Reset Time and Repartition unchecked, then tap START. The update file will then get flashed on the tablet. The end of this installation phase will be over when you see a PASS message along with a green-colored ID:COM box.
  6. Unplug the Galaxy Tab 3 8.0 T311 from your notebook next. Then restart the former. The tablet should now have the Android 4.2.2 Jelly Bean XWUAMH1 firmware among its other firmware. See if that’s the case by opening “About Phone” from “Settings“.

IMPORTANT NOTICE: Should the Odin freeze, you should take the USB cord out first, then reboot the device by force and flash the USB drivers again. Then redo the guide from its very first step.

If, however, the tablet remain frozen in boot loops, you need to boot it into Recovery Mode again and then do as follows: choose Factory Reset/Wipe Data and opt for Wipe Cache Partition. Restart the tablet afterwards.
