It is recommended to install on stock .283 firmware.
ATTENTION!!! If you installed the .283 firmware just for the sake of installing Lolik, then you definitely need to boot into the firmware and make one call. Only then sew Lolik (otherwise there will be no network).

So let's start:
Before flashing you need to throwto external memory cardall necessary files (Fix, root) and it is desirable to clear the internal memory.

1 Turn off the phone, start Flashtool (instead of Flashtool, you can also useQuikIMG , instructions read here )
2 Holding "volume +" we connect the phone to the PC, the indicator should be onblueby color
3 Push the button "lightning "choose Fastboot mode
4 In the window that appears, select "Select kernel to Flash "
5 Find the coreboot.img (do not forget to choose the type of the .img file), click "open" the firmware process will begin
6 After successful firmware, the line will appear: "finished. Total time: X.XXX s"
7 stitchsystem.img (similar to items 3-5, just choose " Select system to Flash "and look for system.img)
8 Successful flashing log for system.img:

9 Turn off the phone, boot into recovery (by pressing the button glitch + with a flash of a white diode when you turn on the phone and display the SONY logo)
10 Go to the Wipe point and put all the checkboxes except System, Micro SDcard and USB OTG (there should be a tick onCache, Dalvik Cache, Data, Internal Storage ), hold your finger on the slider, wait for the end
11 Returning to the main Recovery menu, go to Install, select Storage there: Micro SDcard (above) and look for a zip archive with a fix and install it. After installation, the recovery will prompt you to make a wipe of all the caches, be sure to do.
12 If you need root access, go back to the Install item and put the zip with the root. (SuperSu). At the end of the installation we again make the proposed wipe caches.
13 Returning to the main recovery menu, go to the Reboot item and select System.
14 Waiting for the system to load and enjoy the use of the new Android Lollipop.

The method is suitable for installation on top of .283 and .292 firmware.
