How To: Root And Install TWRP Custom Recovery On Samsungs Galaxy Tab S2 T810/T815 After Updating To Android Lollipop

Samsungs Galaxy Tab S2

Samsung launched their Galaxy Tab S2 in July of this year.  Just like the first Galaxy Tab S, the Tab S2 came in two variants, a 8.0 inch and a 9.7 inch version.  In this post, we will be concentrating on the 9.7 inch version which comes in model numbers T810 and T815.

The Galaxy Tab S2 9.7 originally ran on Android 5.0.2 Lollipop and one variant has already received an update to Android 5.1.1 Lollipop.

If you have a Galaxy Tab S2 9.7 and you want to go beyond the boundaries Samsung place and access the true open source nature of Android, you are going to need to have root access and a custom recovery installed.  In this post, were going to show you how you can root your device and install TWRP recovery on it.

Prepare your device:

  1. This guide is only for use with the Galaxy Tab S2 9.7 SM-T810 and SM-T815.
  2. Charge the device’s battery to at least up to 50 percent.
  3. Have an OEM data cable to make the connection between your device and a PC.
  4. Back up your important contacts, SMS messages and call logs. Back up any important media files by copying them to a PC or Laptop.
