If patience is not your strong suit, we’ve got the Lollipop update for right here. Based off model no. D5803 which has already been bestowed the Android 5.0 update (NCB_1288-5411_23.1.A.0.690_R9C) by Sony, developer i360* tricked the said update to run on fellow D5833 Z3 Compact sets too.
So, you have an official Android 5.0 update right there, even though it’s not exactly officially made for Z3 Compact D5833. And thus there are some caveats. First of all, don’t try it on an encrypted device. And you need to have a TWRP recovery installed to be able to flash the 5.0 ROM we’ve got here for your Z3 Compact D5833. See step 2 of the guide for help. Further, you need to be running KitKat, firmware 23.0.A.2.93/23.0.1.A.5.77 to be exact, with full root access, too. Since this is the official version of D5833, it shouldn’t be problem.
All in all, check the software version in Settings – About phone, make sure it matches either of the two mentioned above, and then get this thing installed with TWRP recovery — you’re all now, though TWRP is sort-of tedious thing to get.
You can switch back to KitKat btw, but you’ll lose all data, including apps, games and game progress, and will need to use SP Flashtool to achieve that.
