T-Mobile Galaxy Note 3 updated to N900TUVUDNF9, Here’s how to root it

T-Mobile apparently was giving mass updates to most of their Android smartphone products, after Samsung Galaxy S4 that has been updated to Android 4.4.4, now it’s time for Samsung Galaxy Note 3 (SM-N900T) which receive an update to N900TUVUDNF9 software version. But don’t get too excited, since it turns out that we did not get an OS upgrade just like the Galaxy S4. Besides the not-so-good news, there is still a great report for Android enthusiasts, as the root is still achievable in T-Mobile Galaxy Note 3 firmware for T-Mobile Galaxy Note 3.


According to the TMo support site, the NF9 software updates only enable the Free In-Flight Texting service. In case you have no idea about this, in September, T-Mobile will offer you in-flight texting, picture messaging and access to visual voicemail. Using this service you could stay get in touch while in-flight, however, this service can only be used on a Gogo enabled devices and Gogo equipped US airlines.

You might think that the NF9 update isn’t too important as it doesn’t affect to your phone performance. But it would not hurt if it always runs the latest official software from Samsung, maybe this update also brings a few bug fixes, but they don’t mention it on the T-Mobile support site. If you are rooted users, you do not need to worry because we can regain root access on T-Mobile Galaxy Note 3 after NF9 updates.
