How to Enter Flash Mode on Sony Xperia XZ2

Are you ready to apply a new update package on your Sony Xperia XZ2? If you are just about to flash a new firmware manually on your phone or if you want to downgrade your device to a previous build of Android OS, you will have to enter and use the flash mode. If you don’t know how exactly to reach this particular environment, don’t worry as everything will be cleared during the following guidelines where we will detail and explain this subject.

The flash mode is therefore required each time a flashing / update operation is implied or when similar other procedures are needed on your Sony Xperia XZ2. Just like the regular recovery mode, or fastboot environment, the flash mode will put your smartphone into a particular state in which the Android core system can be accessed and then modified by Sony’s flashing programs. Shortly, the mode is used for disabling the default Android mode and for enabling the flashing environment that lets you complete different update or downgrade operations.

Of course, entering and using flash mode is an official process since this environment is featured by default within the Android core system. That’s why, for completing the steps available below you won’t have to use third party apps or other risky programs. Moreover, you won’t lose your Sony Xperia XZ2 warranty while taking care of the following steps, so you have nothing to worry about.

It’s important to know that flash mode cannot be reached by using built-in settings. This is a hidden by default environment which can be brought on your Xperia XZ2 only after initiating a special reboot sequence – and that’s what will be detailed during the following lines.

Now, since this mode is usually used on update or downgrade types of procedures, this guide can be applied as a troubleshooting method through which various software related issues can be addressed – for example by reinstalling the stock Android OS you will restore everything back to factory status, meaning that you can get rid of malicious apps, inappropriate tools, malware or unresponsive programs, these being the reasons why you can end up in experiencing boot loops, lags, hangs, screen freeze, battery drain, heating errors, total blackouts and similar other malfunctions.

Since the flash mode is related with other operations, you should backup your Sony Xperia XZ2 before deciding to do anything else. Only in that way you can secure your personal data, info, accounts and files: contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, IMEI / NVRAM data and so on. On your phone you can initiate a backup in different ways: by syncing some files with your Google Account, by securing other packages through built-in cloud storage platforms and even by saving everything via dedicated backup and restore platforms available on Google Play (in that case, make sure you choose only already tested apps for avoiding any possible problems).

Before starting to follow the steps from below check the battery status bar displayed on your smartphone. It’s extremely important to plug in the charger if the power level that’s left on your device is currently showing less than 50% power. If the power is low your XZ2 can get turned off in the middle of the update / flashing process and if that happens different software related problems might cause malfunctions on your handset.
