Hello xda, here's guide from 4pda.ru for bootloader unlocking for Meizu MX4 and Meizu M1 Note.
I'm not author, i just translated this guide from russian to english. Sorry for my grammar.

All your actions with the phone is at your own risk. The authors are not liable. This is just your choice.


Please read full instructions before you start.
Recommended only for experienced users.
This was tested ONLY on MX4 and M1 Note (MX4 PRO - NOT WORKING)


Archive "meizu-unlock" contains:

• custom-recovery_mx4 - custom recovery philz touch 6 for MX4


• custom-recovery_m1note - custom recovery philz touch 6 for M1 Note


• gscript - folder with apk gscript and unlocking script


• patched-recovery_mx4 - patched stock recovery for MX4 (who wants to flash International (index I) firmware to chinese MX4 (index A), or flash stock-customs (deleted chinese soft, game center etc.))


• patched-recovery_m1note - patched stock recovery for M1 Note (same as MX4)
  *********************************** (deleted digital signature checker and checking version of your MX4 / M1 Note (chinese/international))
  


• patcher - loader patcher

UNLOCKING PROCESS:

1. Flash clean stock firmware, do this only on android version: 4.4.2 firmware on MX4 (4.2.8.2A) / 4.4.4 firmware on M1 Note (4.2.0.5A)
   ************************************************** ************** (Android 5.0/5.1 firmwares uboot not patch)
   
   


2. Get ROOT by standard method (flyme account). SuperSu NO NEEDED
   


3. Unpack on your disc (on PC) archive with firmware which you used to flash on your MX4 (4.2.8.2A) / M1 Note (4.2.0.5A) - VERY IMPORTANT!!!
   


4. • Place in a folder with unpacked archive (p.3) file "Meizu_Patch.exe" from folder "patcher" of your downloaded archive and open this with administrator rights.
     -Theoretically, antiviruses can alarm to packer which patcher was compilated (but Dr.Web is fine) / but antiviruses recommended to be closed.
     -If you are afraid about viruses and trojans, skip this step...and all the following.
     
   
   
   • If all goes well - we see a flashing green "SusseccFully Patched" in the patcher round window - continue.
     
   
   
   • If no and you see inscription "Patching Failed!", RED - STOP - something goes wrong and if you continue - BRICK!!!
   
   
   
   


5. Delete from this folder 2 files: "Meizu_Patch.exe" and "uboot.img.bak".
   


6. • Copy a folder "gscript" together with the contents in phone root directory.
   
   
   • Further create a folder with name "UNLOCK" in phone root directory and copy in already patched loader file "uboot.img" from firmware folder from PC (where we started our patch (Meizu_Unlock)).
   
   
   • Pack this firmware (on PC) back in archive (using 7-zip/winrar) with name "update.zip" (default flyme firmwares) - could be useful.
   
   
   
   


7. • Install "gscript.apk" on your phone from "gscript" folder.
     
   
   
   • Add and launch script "unlock.sh". (for menu with adding: flyme smartbar hide - off / use flymetools double tap on right statusbar zone function).
     
   
   
   • Program should show 2 window with root access for gscript, Agree! Wait for one-two minutes for script action (until the yellow lines in the gscript window).
     
   
   
   • Wait 1 more minute and reboot your phone. If it succesfully boot - congratulations, all is fine!!
   
   

Further:

*WARNING!!!* All operations of modules flashing (recovery.img, boot.img etc.) doing ONLY BY STANDARD METHODS, by FASTBOOT command "fastboot flash"!! NOTHING ELSE!!

1. You can flash modified stock recovery from folder "patched-recovery" for MX4/M1 Note (your needs) by command: "fastboot flash recovery patched_recovery.img" and restrict the international version of firmware (in update.zip you can do all changes you want - signature will not check).
   • *CARE!!* If you flash index I firmware with patched recovery, USE Titanium or others to delete/freeze "System Update" from firmware. OTA UPDATE WILL BRICK YOUR DEVICE!!!
   
   
   • *CARE!!* Patched recovery will be rewritten on the usual stock recovery by first full android load, then after command "fastboot flash patched_recovery.img" turn off your phone and hold button "volume up" (+) and "power" before the phone starts (or delete "recovery-from-boot" as alternative).
   
   


2. You can flash custom recovery - and use it for your needs. (Our is Philz Touch) (CWM should work fine too, but not tested).
   • *CARE!!* DON'T try to flash stock meizu firmwares from any custom recovery, we have patched stock recovery for that.
   
   

VERY IMPORTANT Notes:

1. Not allowed "strange" combinations (for example flashing not patched loader and custom recovery). If system goes to bootloop - exit from "half-brick" could be very hard, if it all possible.
   


2. Loader patch and reverse packing stock firmwares should be done everywhere - it will save your time and nerves. You should avoid version mismatch of preloader - uboot - boot.img in smartphone firmware. Effects, bugs, lags can be very different.
   • *IMPORTANT!!* Then, if we flash "custom firmware", it should NOT CONTAINS "uboot.img" and "preloader.bin". All this can be flashed only in stock (modified) firmware, ONLY FROM STOCK or PATCHED STOCK recovery.
   
   


3. "uboot.img" CAN'T BE flashed by fastboot!! Also not allowed doing experiments with "preloader.bin". BRICK probability is very high!!

Meizu will close this soon, then:

1. Code will be changed and patch will finish with error and red stitching error.


2. Patch will finish successfully, but will be added an additional check - by flashing this loader will FULL BRICK.

Then use this patch on releasing firmwares after 01.09.2015 (September 1st 2015) without anyone check, with BIG risk of his phone - FORBIDDEN!!!
