Upgrade Your Samsung Galaxy S3 T999 To Android 4.1.1 Jelly Bean Via build UVDLI3 (OTA)

das Upgrade Your Samsung Galaxy S3 T999 To Android 4.1.1 Jelly Bean Via build UVDLI3 (OTA)

After the recent launch of the official Android 4.0.4 Ice Cream Sandwich upgrade for the T-Mobile Samsung Galaxy S3 SGH-T999 via the UVALH2 firmware update, it looks like even more treats are available for the device as another official OS upgrade bearing the Android 4.1.1 Jelly Bean mark has been leaked.

An interesting thing is the fact that you don’t have to install different recovery tools (like ClokworkMod Recovery) in order to install the UVDLI3 firmware, because the Android developers finally managed to release a software compatible with our device’s stock recovery .

The software is also reported to include a new feature, called Blocking Mode, which allows you to disable some of your device’s features as you fancy. Take notifications, timer, alarm, incoming calls or even a LED indicator for example.

You must be warned, though, that it could still have certain issues or bugs as this is not the final version of the custom ROM. Despite this, though, a small number of users have reported negligible trouble with the update.

In the next tutorial, I’m going to show you how to upgrade your Samsung Galaxy S3 T999 to the latest Android official version, aka Jelly Bean (UVDLI3- build).

Requirements and warnings

  • You could end up with undesired results from using the guide instructions on any other devices than the T-Mobile Samsung Galaxy S3, product number SGH-T999.
  • You have no guarantee that these instructions will be functional under your unique and specific circumstances as the information available in this tutorial is provided with an instructional and educational character only.
  • There will be held no responsibility or liability for whatever happens to your device as a result of using the following tutorial, which means you will be doing everything at your very own risk.
  • Make sure you do not perform any instruction until you have read and understood the whole guide first.
  • As you probably do not wish for your phone to shut down in the middle of the procedure, please ensure that its battery is at least 70%, if not fully charged.
  • Have all your personal data (E.g. contacts, SMS, Wi-Fi passwords, Internet settings) backed up just in case the procedure erases such data. I recommend you to use this simple tutorial, if you don’t know how to do that.
  • Make sure that the Windows PC recognize your Samsung Galaxy S3 when you connect it via a compatible USB cable. If it happens to encounter troubles on this step, just install Samsung Kies and all USB drivers will be automatically installed (if you choose to install this software, don’t forget to turn it off after the installation process, because it may interfere with the updating procedure).

Instructions

  • Your Samsung Galaxy S3’s current firmware version should be the official Android 4.0.4 Ice Cream Sandwich (UVALH2- build). In case you have another version, I strongly advise you to follow the next guide on how to upgrade your T-Mobile S3 version to the UVALH2 firmware.
  • Download the leaked UVDLI3 update for your T-Mobile Samsung Galaxy S3 by pressing this link.
  • Copy the file you’ve just downloaded directly on your S3’s internal SD card.
  • Turn off you device.
  • Now you have to enter your S3 into stock recovery. You can do that by holding down the “Volume Up”, “Home”, and “Power” keys together until the screen turns on. Once you are in recovery mode you can use the “Volume” buttons to scroll up / down and the “Home” or “Power” button to select an option.
  • Select the “Apply update from internal storage / SD card” option, scroll down and select the “UVDLI3” zip file you’ve saved earlier on the internal SD card.
  • Wait a few moments for the process to complete and if your S3 doesn’t reboot itself afterwards, return to the main menu and select the “Reboot system now” option.

Awesome!!! From now one you should experience the Android 4.1.1 Jelly Bean sensation directly on your T-Mobile Samsung Galaxy S3.
