Samsung had just started rolling out the Android 4.2.2 XXUBMH4 official firmware to owners of the Galaxy S2 Plus I9105 mobile device. This update begun hitting devices a couple of days ago, and the direct file has now been made available from the official website. You can grab it at the end of this post. Those of you in Russia will have already begun seeing it appear through the settings application. This is expected to continue for the next several weeks.

Again, like many of the latest updates we see by Android, this one does not have much in store for owners. It’s considered somewhat of a minor upgrade which focus is bringing system stability improvements, as well as bug fixes. Having said that, it’s always a good idea to jump on these when they do come out because a better running firmware is always what you should be looking for. If you are one who has noticed some issues with your device in particular, then it’s a no-brainer to take a file and update as soon as possible.|

If you haven’t updated before you will need to find a guide to help you out to avoid making any mistakes. For those of you already aware of how it’s done, only take the firmware and away you go.

If you want to learn more about this phone it was known as the device by the opposite name. It possessed a rather lackluster 4.3-inch Super AMOLED Plus panel because of its 480p resolution. It was a noticeable flaw on the display side of things, with graphics and 216ppi under the hood, there were some edging mishaps when viewing closely. If displays aren’t the end of the world to you then this won’t matter as much. To make up for what it lacks when viewing from straight on, it makes up for when looking at it from an angle. It has a supreme ability to be seen from the side. Make sure you are wary of this when you have peeping toms. For the most part, it should benefit the owner instead of hurt them.

Its main rivals in the competition are the Sony Xperia S, HTC One S and the Galaxy S3.

Checklist

  • Quickly go through the checklist before starting just to be on the safe side of life. You will have already seen the two links that are the main ones needed including for the Odin package and the firmware that will be flashing. For here, it is important to also have USB Debugging Mode enabled on the deice so that it can successfully connect to the Windows-based PC. I say Windows because the Odin application is not made for Mac or Linux. Go to settings > Developer Options > USB Debugging Mode and put a tic in the box so it is marked as on.
  • It will require the use of ODIN.
  • Verify that the S2 Plus has more than 75% battery power left. This device is getting older now and as they age the battery becomes less reliable and can also drain quicker. The last thing we want is for the handset to turn off during the guide.
  • This firmware works only for the S2 Plus i9105 and will not work if flashed on any other smartphone or tablet. Further, it can cause harm if you try it. Check the model number of your device by navigating to Settings > About Device.
  • Temporarily disable any antivirus or security programs already running on a Windows OS. It does not matter if they are free or paid for. Also put a stop to firewalls if possible because they will not except Odin if installing for the first time.
  • Lastly, it is important to backup the handset in case of data is lost. All data should remain secure when upgrading firmware, however, nothing is guaranteed when it comes to technology. We advise backing up call logs, market apps, SMS and MMS texts, contacts and more. At the very least sync the contacts with Samsung Kies or Gmail.
