This instruction primarily intended for owners Xperia devices X, Xperia Z5, Xperia XZ and other smartphones that for some reason could not update their devices to Android 7.0 Nougat via PC Companion or over the air. This happens if the purchased device was originally intended for a specific cellular operator... Then you can wait for the update for many months until the operator's service deigns to distribute the update for "their" customers.

Secondly, the instructions will be needed by those people who, for some reason, did not like Android 7.0 Nougat, its design, functionality, or so on. Through FlashTool, you can easily rollback to the old firmware based on Android 6.0.2 Marshmallow.

Note from anonymous guest - In addition to the article

I want to unsubscribe about the work done. "PociEnt" - xperia M2 dual (2302), vaccination - official firmware Orthodox kit-kat (4.4.4), operating table - win7 x64. The shoals I encountered:

1) when installing drivers from flashtool \ drivers, pay attention to the following - first, in the file properties, in compatibility, specify Vista compatibility and run as administrator;

2) when selectively installing drivers, black magic appears and nichrome does not work, ticked off everything - it took off (Windows screams for each driver, they say, counterfeit, we choose "install this driver anyway");

3) in flashtool, when you have selected the firmware, on the right, put all the checkboxes in the wipe section (by default, they are not), in other places - do not. (if you do not complete this point, get endless loading, "Will not take off");

4) the topic contains the phrase "the first download takes a very long time." To clarify, if the download takes more than 10 minutes, then something went wrong;

5) if something went wrong, you need to press something sharp (me - with a pointed match) the off button, which is next to the SIM card slots (under the lid) and start all over again.

As a result of the operation, I have a wonderful smart with an excellent system, everything shines and plows. I import contacts with the SIM with one hand, wipe my tears of happiness with the other.

So so. Hey guys. 2018 is in the yard, I bought a new Z2) was updated to 6 android, but yes, as some said - the volume of the sound was not enough. Before that, I specially checked, on the 4th it is really much louder and all the rules. And the battery was somehow suspiciously consumed ...
