Guide: How to Update the Galaxy S5 SM-G900T to G900TUVU1BNG4 4.4.2

Samsung as well T-Mobile support team always advises us to prepare the following important notes to consider before performing the software update.  I have also added some useful insights why you should follow this procedures to keep your  phone in safe.

Recharge the phone – You should make sure your device is fully recharged before performing the software update. Do not also remove the battery during the software update is in progress. A power failures may cause damaged to your device that might results as we so-called “soft-bricks”. If this happens your device may just stuck on Samsung logo or welcome screen and can’t reboot normally.

Backup important data – Even though it is not as always necessarily but if something might went wrong while taking the software update your  your important data is already in a safe place.  You should back-up your important files, including contacts, emails, messages, photos, videos, apps and other stuff. Like I said while during software update process is interrupted there is a possibility that your data stored from your device internal SD card may lose or deleted when a sudden unexpected failure happened and it forces you to perform a factory data reset which basically wipes your phone’s memory.
