Once clicked, all the necessary info will appear in a smaller window.
Additionally, it’ll ask you “Do you want to download this firmware?”
So, click on the Download button if you want to proceed.
Wait for the file to download completely. Once done, you’ll get a “Downloaded successfully!” message.
Hit the Close button > Now, you’ll find a couple of firmware files in the Downloads folder.
Some of these files will have the ‘FILE’ prefix in the name for sure.

Please Note: Make sure to simply delete the fwinfo.xml file from that folder (if available). Otherwise, the FTF (Flash Tool Firmware) will be corrupted.

Now, you’re ready to move to the FlashTool method below.

2. Steps for FlashTool

If you’re not aware of FlashTool, it’s S1 flashing software that works well for all Sony Xperia smartphones because Sony uses the S1 protocol for flashing stock firmware files on their Xperia devices officially.

You’ll have to download FlashTool and install it on your PC.
Now, run FlashTool > Click on the Tool tab from the interface.
Select Bundles > Then click on FILESET Decrypt.
Next, you’ll have to click on the Browse button (three dots icon) to locate and select the Source Folder.
So, just select all the firmware files which have the name starting with the ‘FILE’ prefix.
Once you added those files on the FlashTool interface, you’ll see those files in the ‘Available files’ section.
Now, click on all those added files to select or highlight them altogether.
Then click on the right arrow icon to shift all the files to the right-sided box (Files to convert).
Once done, you’ll see all the moved files on the right-sided box.
Click on the Convert button and wait for the process to complete.
It may take some time. So, have some patience.
The FlashTool will start decrypting all the added ‘FILE’ prefix firmware files.
Once finished, you’ll see a new window called ‘Bundler’.
Here click on the ‘Device’ field to automatically select your specific Sony Xperia model.
Now, type the specific region under the ‘Branding’ field.
Then type the Build Number in the ‘Version’ field.
Make sure to select and move all the files that you can see on the left pane. [But do not select & move .ta files]
So, you’ll have to move the selected files to the ‘Firmware content’ box on the right side.

Please Note: We repeat that do not select and move .ta files for sure. That’s important.

Now, click on the Create button and wait for the process to finish.
The FlashTool will start creating the bundle and once the process is complete, you’ll see a message that says “Bundle creation finished”.
You’re done. Just close the FlashTool window.
