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.
- Finally, you have now created your FTF firmware for your specific Sony Xperia device according to the region.
Note: You’ll find the created FTF firmware file inside the FlashTool firmware folder on your PC. It should be located in the C:\Flashtool\firmwares path by default. However, if you’ve selected another location, check there.
This is all you need. Now, you’re free to flash the FTF firmware file on your specific Sony Xperia device using the FlashTool via PC. Grab a USB cable to connect the handset to the PC, and follow this in-depth guide to successfully install the firmware.
