Great thanks to Darek Z. from MeizuPolska.pl for preparing this tutorial, I am only translating it (with his agree).
Original thread (POLISH) can be found here - http://forum.meizupolska.pl/watek-meizu-pro-5-zmiana-id - it was created to make more easy than similar thread on 4pda (http://4pda.ru/forum/index.php?showtopic=724754&st=160#entry47352757).
So, first some theoretical basics. I found, that each Meizu Pro 5 phone has written information in it's proinfo file and discovered, that each Pro 5 region has own version:
In normal case, access to this partition in phones with locked bootloader is not available, but thanks to BusyBox v1.24.1-meefik, its cp aplet is some kind of exploit, that allows us to get there.
So, let's begin!
What we need at the begining:
0. Installed Flyme OS 5.1.3.0A (on this firmware it works 100%).
1. Working root (Logged to flyme account, settings -> security -> root).
2. Installed SuperSU by Chainfire (with root privillages) - https://play.google.com/store/apps/details?id=eu.chainfire.supersu
3. Installed BusyBox by meefik (with root privillages) - https://play.google.com/store/apps/details?id=ru.meefik.busybox
(steps 2 and 3 are very important, you must use exactly those 2 apps)
4. Installed Android Terminal Emulator (with root privillages) - https://play.google.com/store/apps/details?id=jackpal.androidterm
5. Modified proinfo file (https://mega.nz/#!8ZJ01aZK!2WfKciJk1yQQK3SwimVylqB5JJkMsEGua32_76hTBac). We unpack it and move .img file to our sdcard.
When all steps from 1-5 are ready, we run Android terminal and type those commands (all command we confirm with ENTER):
Everything should look similar to this: https://drive.google.com/file/d/0B9jnuCte0sZ0WEY0WkxabUpjVmM/view?usp=drive_web
After that we reboot our phone, and to make sure everything works, we open terminal again and type commands:
If we see there machine_type=M576_intl_official, than everything is fine, and we can use international firmware
After that, we can unlock bootloader using this thread: http://xdaforums.com/meizu-mx/general/tutorial-unlock-bootloader-meizu-pro-5-t3303127

Code:
machine_type=M576_unicom_custom - U version = China Unicom (my phone)
machine_type=M576_mobile_public - A version = Chinese
machine_type=M576_intl_official - I/G version = InternationalIn normal case, access to this partition in phones with locked bootloader is not available, but thanks to BusyBox v1.24.1-meefik, its cp aplet is some kind of exploit, that allows us to get there.
