How to Update Galaxy Tab 3 8.0 SM-T311 to Android 4.2.2 ZCUANA1

A tablet for which there are many users in China is none other than Galaxy Tab 3 8.0 SM-T311. In January, new firmware came out so that this gadget’s owners could update it to Android 4.2.2. Find out more below!

This new official firmware is known as ZCUANA1 and it works only with the Galaxy Tab 3 8.0 T311. In case you have another model, we suggest using a different guide. Ours is going to brick your device.

There are various goodies you can enjoy once your tablet is upgraded: a new Gallery app with superior speed when loading, a new set of sounds for wireless charging and low battery bug fixes, USB debug white-list, no Bluetooth audio streaming bugs, the possibility to long-press the WiFi and Bluetooth icons in Quick Settings so that you can easily toggle the on/off state and a whole new set of download notifications.

Using Samsung’s KIES to apply the update is possible; but you need to own a Galaxy Tab 3 8.0 SM-T311 which operates a stock ROM. In case you stick to our tutorial, though, here’s what you should know: if the tablet is rooted, the ZCUANA1 shall be responsible for the following cons: the device will have its root access revoked and he system partition is going to be erased. Don’t worry about the important data: it is going to be preserved. The internal and external SD cards will also come out of this unaffected.


Once the disadvantages have been laid out and you aren’t appalled, proceed to the following set of pre-requisites:

  • turn USB Debugging on;
  • download the Jelly Bean 4.2.2 ZCUANA1 (here’s the China variant) and Odin from this page on the laptop;
  • create two sets of backups (one should be a standard one and the other should be a full NANDroid backup);
  • which must have Windows among its specifications;
  • USB drivers appropriate for your gadget must be flashed on your notebook;
  • if the tablet’s battery needs it, fully charge it;
  • on the tablet and notebook, be sure there are no security programs turned on (after you’re done with the tutorial, you can enable them again).Galaxy-Tab-3-8.0-T311
