Unbrick AT&T Galaxy Note 3

Providing root access to Android devices allows users several capabilities that help them to maximize the use of the phone or tablet. While rooting allows for a better performance, more customizations, and an overall more sophisticated software, giving root access and installing custom mods does not always happen efficiently, or without any complications. For one, installing a file that has previously been modified before you download it can brick your device. This can happen whether you are rooting or installing a custom ROM or installing an official firmware.

Bricking can be classified into two: soft brick and hard brick. In soft brick, the device turns on but a yellow triangle appears on the screen. This kind of brick can easily be solved. Meanwhile, in hard brick, the device shows only a black screen and it does not react to any action you perform. This case is much more difficult to solve, and you will need to bring your device to a support center for them to solve the issue.

This article will teach you how to unbrick your AT&T Galaxy Note SM-N900A. Those who have used Odin before will find it to their advantage and the entire process will be much easier.
