First off, the procedure is in great need of UCU1ANCE official firmware. Only when your smartphone will have it will the upgrade truly happen.

The new OS will land on your device if you’re based in the USA, use AT&T and your phone’s name is Samsung SM-G900A. The new firmware has been made especially for this model. When you upgrade another one with the this firmware, the phone or tablet will get affected.

Apart from using the device we advised, you will have to know what happens when a rooted Galaxy S5 G900A gets the new firmware. The most important part of a rooted gadget is its root access; the update will revoke that. Also, the upgrade will also damage the system partition. Nothing this bad will happen to the data.

  • a regular set of backups must be created;
  • your handset’s USB Debugging option needs to be turned on;

  • look at the phone’s battery and, if it’s empty, be sure to charge it;
  • this device’s security software will have to be deactivated;
  • also, make sure the phone’s own software firmware is turned off.

Step by step instructions

For every update available today, the first step everyone needs to perform is this: download certain packages on your notebook.
