How to Flash the Latest generic Android Nougat 7.0 for Sony XPERIA L1 G3311
a) first thing which you do, check your device firmware version (if your Xperia phone already have the latest version, you don’t need this tutorial)
b) download & install latest Flashtool from this post
c) download also Newest Android 7.0 43.0.A.5.79 Nougat for Sony XPERIA L1
d) paste the Firmware FTF file downloaded in step c) to folder „ROM“ included in the XPERIA Flashtool
e) Run the XPERIA Flashtool, click on flash and select downloaded the firmware, then click ok. Important – if you do not want to remove any data from your telephone, just uncheck flashing userdata.sin file. All data will remain on your phone, but sometimes it can cause additional troubles. So it is enough (and I suggest that) to do the backup of your personal data, then proceed with clean installation and then restore your private data.
f) turn off your phone and when Flashtool shows pop up window, attach the phone to PC with holding volume down button
g) after few minutes all is done and your phone gets the latest firmware.
