A custom ROM that is running on your Android operating system always replaces the stock ROM environment. Since swapping ROMs is a problem, there is always an element of risk to installing a new ROM on the Samsung Galaxy S5 smartphone just like there is with any other device. However, for many that risk is easily justified when you get to experience what a custom ROM running on your device feels like. Many people choose to update to a custom ROM to test out newer versions of the Android operating system, and it’s a reason that will likely continue to be valid for years to come with OEMs and phone carrier networks choosing to stall updates after just a few years to entice you to upgrade to a newer device. There is also the added reason of hardware changing ever so quickly, and the newer versions of Android operating system cannot run properly on the older device — though it’s hard to believe that isn’t all part of the plan too.

Here is everything you need to install the Vision-X custom ROM on the Samsung Galaxy S5 smartphone from T-Mobile subscribers by using a custom recovery image and a computer. You should always transfer your new ROM files using the computer first because it’s the safest way.

  5. Once you are within the custom recovery environment, tap on the Backup button and proceed to backup the Android operating system so you can restore it again later.
  6. Head back to the main recovery menu and tap on the Wipe button to wipe your data and apply a hard reset on the T-Mobile S5 smartphone, so it is ready for flashing a new ROM on the device.
  7. From the main recovery menu yet again, tap on the Install button this time and follow the guidelines to upload your Vision-X custom ROM zip file from the internal storage SD card.

You can always go back to using the stock ROM you were running before by entering the recovery environment once again, taking a backup of your data and then applying another factory reset. Now download the Odin application and download your stock ROM from the Sam Mobile website.
