Recently, we noticed that Sony pushed out an update to fix the Accelerometer issue on the Xperia X Performance. It seemed inevitable that they will release Nougat on the device sooner or later. Sony seems to be rolling out the Nougat update for Xperia X Performance (F8131) and X Performance Dual (F8132). It is only rolling out in select regions so far, but there are firmware files already available. The firmware files from Russia and Thailand are available so far, and you can install them on your respective devices.
Firstly, we need to download the Firmware files. There are two versions, so you need to download the variant for your respective device.
- Xperia X Performance (F8131) 39.2.A.0.327 Russia Generic (Decryption Key: !JaG5_3yJXT-_I3msNatz4-MUDBe3Ek8UCSWWWlBTWl0)
- Xperia X Performance Dual (F8132) 39.2.A.0.327 Thailand Generic (Decryption Key: !EK7j8fEh7XSzGVZGseEwcdDAbBCYwfPAnowazM-Dt2U)
- A Windows PC
- Sony PC Companion for drivers
- USB Cable (double check for faults)
- At least 60% battery remaining on your device
If you are running Windows 8 or above, you might have a few issues installing Flashtool. Win8 and future versions enable driver signature enforcement by default. This means that no matter what you do, Flashtool drivers will not be installed, unless you Disable Driver Signature Enforcement on startup. To do this:
- Press the Windows key + R together and in the ‘Run’ box type:
Now make the following selections to boot into the Start Up Setting Screen: Troubleshoot > Advanced options > Start Up Settings > Restart
Then, when the machine restarts, select number 7 i.e. “Disable driver signature enforcement”. Your machine will start with Driver signing enforcement disabled until the next reboot.
/r /o /f /t 00.
- Now you can install the Flashtool drivers.
Windows will warn that the driver is not signed and will require you to confirm the installation.
Once the installation is complete, reboot the machine
Setting up the device
On your Xperia device, make sure you have enabled “Unknown Sources” under Settings, Security. Also make sure you have turned on USB Debugging under Developer Options. If you don’t find developer options, you can enable it by going to About Phone->Tapping the build number about 7 times in succession.
Flashing the Firmware
Note: Make sure you take a backup of your device before proceeding.
- Open Flashtool and click on the Lightning Bolt on the Top-Left corner of the window. This will bring up a Bootmode chooser. Choose Flashmode and click OK to proceed.
- Select the firmware build version that you want to flash from the “Firmware” pane. Ensure the device variant is the same as the model number of your Sony Xperia device.If you want to retain your apps, data and media (photos, videos, music), then ensure that the “USERDATA” option within the “Wipe” pane is unticked. However, we recommend that when upgrading a major new Android version, a clean install is the way to go. In this case, tick all options under the “Wipe” pane. This will wipe all of your data though including your photos and videos, so please ensure you have these backed up elsewhere.
- After choosing your firmware file, click Flash and Flashtool will begin preparing your firmware files to be flashed. After preparing, a pop-up will appear prompting you to connect your device. Follow the on-screen instructions and connect your Xperia X Performance.
- Once successfully connected, Flashtool will start installing the firmware on your Xperia device. Once done, it will indicate that the installation has been successful, you can disconnect your device now and boot it up.
Note: It may take a few minutes to boot up for the first time, this is expected.
We’ve now successfully flashed Nougat for the Xperia X Performance!
