Below you can find the latest firmware for the phone and also two tutorials/manuals – how to unlock the bootloader and how to backup the original ROM customization.
How to Flash the newest generic Android Nougat 7.0 for Sony XPERIA XA F3111
a) first of all, check your device firmware version (if your device already have the newest one, you don’t need this tutorial)
b) download and install Newest Xperia Flashtool from this thread
c) download also latest Android Nougat 7.0 33.3.A.1.97 for Sony XPERIA XA
d) paste the FTF file downloaded in step c) to folder „ROM“ included in the XPERIA Flashtool
e) Start the XPERIA Flashtool, click on flash and select downloaded the firmware, then click ok. Important – if you don’t want to delete any data of your phone, just uncheck flashing userdata.sin file. All data will remain on your device, but sometimes it can cause additional troubles. So it is better (and I Preferred that) to do the backup of your personal data than proceed with clean installation and then restore your personal data.
f) Switch off your phone and when Flashtool shows pop up window, connect the phone to PC with holding volume down button
g) after few minutes all is done and your phone gets the latest firmware.
