When it comes to software updates for Android smartphones, Sony is going the best so far. In the past few months, Sony has been leaving all other manufacturers far behind in terms of Android software updates for its Xperia series. Sony has been rolling out updates, one after another and sometimes the users just get confused which one is the latest firmware and which one they should flash on their device, confusion with the firmware region is another thing that might occur. Since the firmware updates are rolled out through OTA or through Sony PC Companion, they take much time to hit different regions. Some regions receive the updates instantly while some receive the updates after long delay and this is something the Xperia enthusiast who are always willing to get the latest and greatest version of Android on their device, might not be able to tolerate. Users can also receive an update by changing the CDA of their device, but that can be done by going a little out of the way, and things should be kept as simple as possible.
Updating your Xperia device manually is the best choice if the update isn’t hitting your region and you are not seeing it coming your way anytime soon. If you’re going to flash the Generic firmware on your device, you don’t actually need to worry about the region as well as the region specific firmware comes with some bloatware that you can probably remove from your device, but you need to be careful with flashing a carrier branded firmware on your device. Flashing the firmwares manually is possible through flashing a Flashtool Firmware File using Sony Flashtool. Although there’s a number of people who post FTFs for different Sony Xperia Devices on the XDA developers forum as soon as a new update arrives, and there’s a number of some sites as well who post the FTF files, but you might just fail sometimes locating an FTF file of your choice for your Xperia device. In this case what you can do is, you can download the stock firmware from Sony’s server, create your very own FTF file and flash it on your device.
Before you start wondering how you can download the firmware from Sony’s servers, you may not be aware of Xperifirm, a great little application by XDA Senior Member LaguCool. Xperifirm allows the Xperia device users to check the updates in all the available regions, and shows the build number as well. You can simply choose your desired firmware and download the FILESETs and then compile the FTFs in order to flash. Downloadingthe firmware and compiling up the FTF might seem a difficult job, but it won’t be difficult anymore once you scroll down. In the succeeding guide we are going have a look on a comprehensive method that will help you to create the FTFs files successfully once you have downloaded the FILESETs for your desired firmware. Let’s start it now.
How to Download Sony Xperia Official Firmware FILESETs using Xperifirm:
- First of all you need to know what’s the latest firmware for your device. You can always check the latest build number on Sony’s official site.
- Download and extract XperiFirm.

- Latest Release: Build number
- Now see what build number matches the latest build number, and what region do you want to download it from.
- A firmware with the operator name like “Customized IN or Customized US” is a generic firmware, that means this firmware has no carrier limits of carrier boundaries. While other firmwares will be carrier branded.
- Make sure that you choose the firmware properly, do not download a Customized firmware on a Carrier Branded device and do not download a Carrier Branded firmware for an open device.
