T-Mobile Galaxy S5 updated to Android 5.0 Lollipop G900TUVU1DOB1, root little bit challenging

T-Mobile Samsung Galaxy S5 (SM-G900T) official Android 5.0 has been rolled out a few days ago with software version G900TUVU1DOB1. This is the ninth update received this smartphone, previously the NK2 update has been released a few months ago. The majority of users should updated to the latest version of the firmware now, but there are a few folks who still delay to take the OTA, fearing the root access on the official Lollipop updates (OB1) for T-Mobile Galaxy S5 will be dropped.


The Android 5.0. Lollipop update brings significant changes to the Android OS, you can assume by looking at the OTA file size that is almost 1GB. In addition to Material Design UI and sleek animation you can expect a better performance and more efficient battery. Apart from bringing the most awaited Android OS, the OA6 update also delivers small enhancements to the Wi-Fi calling.

In order to get the official Android 5.0 OTA update for T-Mobile Galaxy S5, your phone must be in stock and unrooted, because as usual, the OTA installation will be unsuccessful when it detects there is a lot of changes in the system, even in some cases, it could make the phone bricked.

Unfortunately, until now no one has confirmed if the previous method (CF-Auto-Root or towelroot) can be useful to regain superuser access. But most likely, it’s incompatible because of the many changes on the Lollipop updates when compared to previous Android releases. When forcing to make use of CF-Auto-Root you will get a security notice on the phone.

If you have not yet updated the phone to Android 5.0, we advise you to delay the OTA. When still on KitKat, you can unlock the bootloader and install TWRP recovery, so that you can easily flash the official Lollipop stock rooted ROM instead of downloading the OTA.
