T355XXU1AOE9 (XXU1AOE9) Update For Galaxy Tab A 9.7 LTE T555


You can now update your Samsung Galaxy Tab A 9.7 LTE T555 to the Android 5.0.2 Lollipop with the T355XXU1AOE9 (XXU1AOE9) firmware, and the update was recently published by Samsung this week. So for everyone with the tablet in hand can now get into the System Update (OTA) or Samsung KIES (by simply connecting the tablet to computer) to see whether the XXU1AOE9 is there.

But of course expecting its availability in either OTA or KIES takes time, since many regions are expecting the same firmware therefore Samsung should push it gradually to serve all the supported regions and do not be worry because you can take the manual installation to deliver the same update to your tablet, and this post will guide you through the entire process.


If you are interested, then you can continue reading this post and firstly I advise you to read the points listed in the preconditions section before following the steps from manual installations written on this post, and you will be told of what to do, what you will get, and what you don’t need to do, all will be covered in that section guys.
