Update Galaxy S4 Mini LTE with Official XXUBML1 Android 4.2.2 JB Firmware

Even though everyone is expecting the Android 4.4.2 KitKat OTA update for their Android based devices, it seems that Jelly Bean is still the latest firmware released on the market. For example, the Galaxy S4 Mini LTE had just received the official XXUBML1 Jelly Bean Android 4.2.2 OTA software, which means that KitKat is still far away from the S4 Mini users. Anyway, since we are talking about an official roll out, during the following guidelines I will teach you how to manually install the Android 4.2.2 XXUBML1 firmware on your SGS4 Mini LTE.

Regarding to the upcoming Android 4.4 KitKat release, it seems that the Galaxy S4 Mini will be able to receive the OTA only during March, or even later, this year. Until then, Jelly Bean will be running on your phone, unless you choose a custom ROM firmware like CM11 or AOKP instead. Anyway, leaving these aside, we should concentrate on the present operation which represents the manual installation procedure of stock Android 4.2.2 Jelly Bean XXUBML1 firmware on the LTE version of Galaxy S4 Mini.

Since I have mentioned the Android 4.4.2 based custom ROMs, you should know that not all the users are appreciating the unofficial updates. So, if you do flash a custom ROM and find the same unsatisfying, then you can anytime return to this tutorial for applying the stock and also official Android 4.2.2 OS, which by the way (and as I have mentioned several times by now) is dubbed as XXUBML1. Furthermore, this step by step guide can be used if you want to restore the warranty of your smartphone – as you know the warranty usually gets void once you root your device, unlock its bootloader and so on.

Moreover, due to same reasons, this tutorial is compatible with both rooted and un-rooted Samsung Galaxy S4 Mini LTE. Actually root access isn’t required when installing official updates like the present Android 4.2.2 JB XXUBML1 firmware. So, if your phone is rooted, after applying the guidelines and the steps from below, the root access will be revoked, the system of your device relocked and the factory and default restrictions reinstalled.

Now, if we are to discuss about the Android 4.2.2 Jelly Bean XXUBML1 OS you should know the following: the software is stable, comes without bugs or issues and it will smoothly run on your S4 Mini. Furthermore, the OS is bringing stock features, apps, capabilities and stability improvements so you will be enjoying the pure Jelly Bean system. With this ROM installed you will be able to receive further OTA updates – which is quite important since on rooted handsets you aren’t able to do the same (you can apply OTA updates only by manually installing the firmware).

Since we are dealing with an official update and since we are talking about a Samsung branded device, for being able to manually flash Android 4.2.2 JB XXUBML1 on your Galaxy S4 Mini LTE, Odin will be used. Odin is an official program that is developed and offered by Samsung. Therefore you will not be using custom apps for completing this guide – also a custom recovery image isn’t required on this operation.

What you do have to perform before going any further is a backup procedure. It’s true that when using Odin is quite unlikely to lose your data, but the best will be to avoid unpleasant things from happening; because of that you still have to save everything that’s important for you including text messages, call logs, internet settings, market apps, EFS folder and so on. Get the backup and restore apps from Google Play – don’t worry as you will easily find free distributed apps.

Also, before heading to the proper installation procedure you have to prepare a computer, a Windows based one as Odin can be installed only on the same. So, on the mentioned computer first deactivate (temporarily only) the antivirus, antimalware and Firewall protection. Do that because usually the security programs are interfering with the update operation. Also, since you will have to connect your smartphone with your computer, on your device go to “menu – settings – developer options” and enable the USB debugging option. Moreover, your phone must have more than 50% power left; if not the best will be to charge its battery first – it might get bricked if it gets turned off in the middle of the update procedure.

Finally, you should remember that Android 4.2.2 XXUBML1 firmware has been officially released and rolled out only for the Samsung Galaxy S4 Mini LTE. Therefore, this step by step guide is being compatible only with the mentioned Android based device.

How to Update Galaxy S4 Mini LTE with Official XXUBML1 Android 4.2.2 JB Firmware

  1. On your computer you need to download Odin.
  2. Unzip the file and install the same.
  3. Furthermore, the S4 Mini drivers must be installed on your PC. If the drivers are not there, use Samsung KIES for achieving the same.

  8. With the handset booted in download mode and with Odin running on your PC you need to connect the devices by using your phone’s USB cable.
  9. Odin will try to recognize your phone: on the program the ID:COM section will turn yellow or blue and the “added” message will be displayed.
  10. If that’s not happening then you will have to repeat the steps from above – also try to reinstall the drivers on your computer.
  11. Good, now from Odin select the option dubbed as “PDA”.
