Today we have the Sony Xperia Z that has a new Firmware update for it. The next edition is called 10.3.1.A.2.67, and it is a new Android 4.2.2. This official firmware has been made available for manual installation procedure by the kind folks over at Sony so you can load it up that way if you wish.

There is also an automatic OTA brought out for owners. Bear in mind that to receive the update straight into the settings you will first need to be running a stock version of the firmware already. If you have rooted the phone or anything in that manner, then you only have the one option of getting it manually.

It is always essential not to endeavor to put this on your Xperia Z unless you know what you are doing. If you have performed it before then you will be OK. The method for fixing it on the phone has not changed one bit. However, if you do not know what you are doing, then search for a guide to help you because you will not be able directly to load the file provided by us.

Firmware upgrades may start to slow down for this version of the Xperia because the new Z1 will be released in most countries around the world in the next few months. All up it will take over and be the new flagship model of the Sony mobile product range. Don’t worry too much, though, because the updates should continue to keep coming even when this device is older.

What will be fascinating to observe is if it has a new 4.4 Kit Kat, because the announcement is out for Galaxy range, which usually means that the other competitors will follow suit sooner than later. Don’t be surprised if it comes with the new Z1 and has a delay for the soon to be old Z, however.



  • Do not start the tutorial until you have back up all of the important data such as contacts to the device’s internal storage known as the SD card. It is the way we recommend because it is simple, and it is also why Samsung has implemented it.
  • There are other options you can pursue as several different applications that are available from the Google Play store if you would prefer doing it another way. It does not matter how you do it, but it would be foolish to start this guide without backing up because that opens the doors to losing data.
  • Every device is running Android 4.2 Jelly Bean and up has new options called Developer Options. It has been made to create a simple way to access options we want to use here such as the USB Debugging. In some cases, it has no been accessed yet so we will show you how to unlock the hidden menu.
  • Click on the notification bar and go to Settings > scroll down to About Phone > scroll down to the bottom where it says build number. Quickly tap on this build number several times and it will tell you “you are now two steps away.” Click again and it will say “you are now one step away.” Click the final time to unlock the secret Develop Options.
  • Temporarily disable any antivirus or antimalware software programs there may be running. They can sometimes interfere with the communications, making what we are trying to do here much more difficult than it needs to be. This guide poses no threat for viruses at all, so there is nothing to worry about there. Just make sure you turn it back on again before you start browsing the web or else the computer will be vulnerable.

It is a little different to the usual ODIN we are so accustomed to using; it may vary in time compared to what you are used to. Do not be surprised if it takes upwards of 15 to 20 minutes before it finishes. Alternatively it could be sooner than the usual ten minutes. Make sure you do not touch anything including the WIndows Pc or the smartphone until it is finished
