Well it was released very briefly a week or so ago then Sony pulled it from the servers. It is probably possible to still find an FTF file of it if you really looked. The Xperia E6653 will use Version: 32.3.A.0.372. Apparently Sony says there were some issues with it I have however installed it on my Z5 and it's perfect. I have no problems.
I upgraded mine a week ago , but it doesn't work well: hotspot with Bluetooth doesn't work. In consequence I wish to downgrade to 6. Regards
google for the correct ftf file for your model and then use flashtool to write it onto the phone. Make sure you get it right !
