The T-Mobile Galaxy S4 had received a new OTA, the JB 4.2.2 UVUAMDL firmware. But if your handset is on a custom ROM, or rooted, then the OTA can’t be received and installed. Furthermore, if you will have to downgrade your Galaxy S4 to stock Android OS, or if you will have to restore the warranty of your handset (the warranty gets void when you root your phone) then you will have to use a manual method for installing the official Jelly Bean 4.2.2 software. So, for all that, use this step by step guide and update your T-Mobile Samsung Galaxy S4 to official Android 4.2.2 Jelly Bean UVUAMDL firmware.
This guide will take you through the installation procedure of an official update. So by completing the steps from below, the warranty of your Galaxy S4 will not get lost. Actually, if your device is currently rooted or based on a custom ROM (or if you have completed an overclock operation), now you will be able to revoke the root access and restore the warranty. Therefore, the root access will be revoked, so you will have to use a root method that is suitable with the new JB 4.2.2 UVUAMDL OS – if you will need to unchain the system of your phone. Don’t worry though as this update operation is compatible with both rooted and un-rooted T-Mobile Samsung Galaxy S4 devices.
Since we are talking about an official update and since we will flash the UVUAMDL firmware on a Samsung branded handset, for completing this tutorial we will use Odin. Therefore, you don’t have to worry as there won’t be used complex and risky apps or programs. Odin, is a dedicated tool used on update and root operations; the program is designed and offered by Samsung, so you have nothing to worry about.
Of course, if Odin will be used, then you will have to use a Windows running computer, your T-Mobile Galaxy S4 and its USB cable. Also, on the computer the S4 drivers must be installed – download Samsung KIES and install the drivers via the program. Also, as usual, on your computer you have to deactivate the security protection; then you need to enable the USB debugging option on your smartphone and you also have to charge the battery of the same. All these are preparation tasks that have to be applied if you want to successfully install the stock JB 4.2.2 UVUAMDL on your Galaxy S4.
Don’t forget to backup the SGS4 data, this being the most important thing to do before heading to the flashing procedure. Save everything you need to, including EFS folder and if possible the current ROM – Nandroid backup.
Now, since the UVUAMDL software is the stock Android JB OS released for your T-Mobile Galaxy S4, the firmware will be coming only with stock features and minor bug fixes. If you want to improve the JB experience or power up the performances of you handset, then don’t hesitate and update your smartphone with a custom ROM, or even consider in overclocking your T-Mobile SGS4.
Anyway, do note that this guide is compatible only with the Samsung Galaxy S4 model number M919. Applying the next steps on a different or similar Android based device will probably brick your handset.
