No. A newer build for SM-T311 is available: T311UBUBOI1. Install it instead of T311UBUBNK1 unless you need this exact version. The previous build was T311XXUBNI3.

Download the package for your region (CSC) and unzip it. In Odin, load each file into the slot with the same name: BL, AP, CP (if the package has one) and CSC, or HOME_CSC to keep your data. Odin checks the built-in checksum of every .tar.md5 file before flashing. The Samsung Galaxy Tab3 8.0 must be on bootloader binary U (30) or lower.

This build uses bootloader binary U (30). It can be flashed on a Samsung Galaxy Tab3 8.0 running binary U (30) or lower; if the device already has a higher binary, Odin stops with "SW REV CHECK FAIL". 21 other builds of this model use the same binary, so you can switch between them in both directions.
