Here is the procedure itself (the beginning is standard and fully quotes the first steps
instructions dear biboy85 ):
1. On your computer on Windows 7/8 / 8.1, install the Windows Phone 8 SDK by downloading the link from the header
"Folder with everything you need" 2. Download the utility version set (from version 4.3.0.0 to 4.6.0.0) for unlock
from Yandex . Unzip the rar file somewhere on your pc
3. If your device was previously unlocked for 2 applications, go to the Developer Registration utility from the Windows Phone SDK and block your smartphone back. If you have not done unlock once, then go straight to the fourth paragraph.
4. Make sure that the date and time are synchronized on the PC and the phone (the hour / minute accuracy is quite sufficient, synchronization up to a second is not needed)
5. Make sure that the PC and the phone have an active Internet connection (WiFi is not necessary - my unlock worked if there was only a 3G connection on the phone)
6. Make sure that the phone has unlocked the screen and the screen is active.
7. From the folder where utility installations are located
Aiyingyong Run version 4.3.0.0, click on the big button and wait for the installation to finish. Close the installer window by clicking on the cross in the corner and in no case the button below (it serves to update the software from the official site, but the latest update, for some reason, just does not work):
8. Launch the Windows Control Panel and change the date / unit format to "Chinese Traditional, Hong-Kong S.A.R"
9. Connect your phone and wait for Windows to detect it. Make sure the screen is active again. Launch the unlock utility by clicking on the icon on the working raft. The utility gives a list of recent changes and again offers updated software. We do not need it, so again we ignore the big button and click on the cross in the corner:
10. The utility will detect your phone, what will be the message in the information panel on the right - brand name, phone model, etc. Now there are two possibilities.

but) the big button to launch unlock will be blue - i.e. It is possible to start unlock immediately! Click on the blue button and after half a minute go through the item
12. ---
b) the big button remains gray :( - something “didn’t like” the Chinese utility and it is necessary to continue. Click on the cross in the corner. The utility’s closing dialog appears. Check the box next to the lower option (in the picture - in the red square) and only after that click to the exit confirmation button (purple square). This option unloads the service that monitors the program updates from memory, which, as already mentioned, is not needed.
11. Go through the item
7. and launch the next version of the utility installation - 4.3.3.0, or 4.4.3.0, and so on, repeating the steps 7-10 until the treasured button for unlocking will not be blue. I walked version 4.5.0.0, and my son (he has the same L520) - for some reason - only to be followed by 4.6.0.0. You can, of course, immediately after the 4.3.0.0 4.5.0.0 to try to pass on, or even on 4.6.0.0, but wonder about the possibility of being successful not undertake. Anyway - what matters is that we should start with an installed 4.3.0.0 and then the following version over the old one.
12. In the end, the button will turn blue and after pressing it and still half a minute of waiting, the utility screen should look like this:
13. Congratulations! - Your phone is ALMOST unlocked into 10 user applications :-P To complete the process, you still need to restart the phone.
14. The Chinese utility has done its job - it's time and the honor to know (otherwise it has a lot of third-party services that are waiting in the wings). We launch the regular utility uninstall program and confirm the process by pressing the button in the red box below. Do not forget to return the format of the dates / units of measure in the commonly used by you:
