STEP 1: Download Firmware

1. To begin with, you will have to download the firmware for your H8416 with the desired region. For that, launch the XperiFirm software on your PC
2. Next, select your device (Sony Xperia XZ3) from the left-hand menu bar and select the model number H8416.
3. Go through the firmware information section and select the region.
   
4. Then on the right side, click on the latest available firmware that it displays. It should be present just beneath the Available Firmware section.
5. A popup dialog box will then appear, click on the Download button.

The downloading process will now begin and once that is done, you will get an Unpacked Successful message. Click on OK. You could also go through our guide on how to install stock firmware on Sony Xperia using Xperifirm and Flashtool to gain more knowledge about this tool.

If you have flashed the firmware using this guide, then you don’t have to follow the second and the third step. If not, you can flash the firmware using the Newflasher tool command.

STEP 2: Boot your Sony Device to Flash Mode

1. You will now have to boot the device to Flash mode. To do so, power off your device. Then press and hold the Volume Down key and connect your device to the PC via the USB cable.
2. As soon as the Notification LED light turns green (while the device is in a switched-off state), it indicates that the device has been successfully booted to Flash Mode.

STEP 3: Flash Sony Xperia XZ3 H8416 Firmware Files

1. First of all, extract the Newflasher inside the same folder where the firmware files are present (that you got from the XpeirFirm tool in STEP 1).
2. Now launch the NewFlasher application on your PC.
3. Type in n and hit Enter. Then again type n and hit Enter. You should now be taken to the flashing stage.
4. Make sure to connect your device to start the upgrading process.
5. Now press Y and again Y to reply in the affirmative. The conversion process will then begin and once that is done, the tool will notify you that is now safe to disconnect your device.
6. Hence, disconnect it from the PC and then press and hold the Power key to boot it to the converted firmware.
