How to Flash Sony Xperia Firmware with Newflasher

This guide explains how to flash Sony Xperia firmware with Newflasher tool on latest phones: Xperia XZ2, Xperia 1 and more. For many years Flashtool has been the go-to utility for Sony Xperia users if they wanted to upgrade/downgrade firmwares or even debrand their device by installing a generic firmware and removing all sorts of branding and bloat from the system. Further, Flashtool gained its pinnacle when it integrated XperiFirm – this gave users a seamless experience in downloading their desired firmware file and then flashing it on their devices under one tool. How

Flashtool is a great piece of software and a must use for any Xperia owner but unfortunately even Flashtool has its limits. The limitation comes in if you have a newer Xperia model than Xperia XZ1 because even the most updated version of Flashtool doesn’t support newer devices just yet.

So, if you want to flash a newer firmware on latest Xperia devices then you’re in luck because developer “munjeni” has solved this problem by creating a new command-line based flasher for newer Xperia models called Newflasher. Don’t get worried by reading “command-line based” because it is even easier to use than Flashtool if you follow the steps properly mentioned in this guide. The best thing is that you can also use Newflasher tool to flash older Xperia models as well.

Newflasher: Flash Sony Xperia Firmware

So, as powerful Flashtool is, it can’t help you upgrade/downgrade or flash any firmware if you own devices from the list below but Newflasher works with these:

  • Xperia XZ2.
  • Xperia XZ2 Compact.
  • Xperia XZ2 Premium.
  • Xperia XZ3.
  • Xperia 10.
  • Xperia 10 Plus.
  • Xperia 1.

Sony Newflasher is as powerful as the Flashtool in terms of features. Like in Flashtool you can choose what to flash, skip factory reset etc. All of these functions can also be performed using Newflasher so there is no shortage of features between the two. The software you’re going to need to use Newflasher effectively are listed below along with their role during the process.

1. Downloading Xperia Firmware

At this point we are assuming that you’ve downloaded all prerequisites software and installed them. So, downloading the desired and correct firmware for your Xperia device is critical. Make sure to see the exact model of your Xperia device before starting anything.

I’ll be referencing Xperia XZ2 Premium (H8116) in this tutorial throughout as I used that device to write this tutorial. To check the exact model number of your Xperia device, simply go to Settings > System > About Phone > Model. Once you know the exact model of your Xperia device, remember it or write it down because it’ll be used shortly. For me the exact model of my Xperia device is H8116.

Now let’s start downloading the correct firmware for your Xperia device. I’m downloading Android 9 Pie firmware 52.0.A.8.131 for Xperia XZ2 Premium (H8116).

NOTE: If Xperia Companion is running close it completely from system tray so that it won’t interfere with the process below.

Step 1 – Open FlashTool. Let it sync its devices database from the internet. It will take few seconds so please be patient.

Step 2 Click on XperiFirm button from the top menu of FlashTool.
