[Meizu MX] slowsunset:
Hello xda, here's guide for bootloader unlocking for Meizu MX4 and Meizu M1 Note.

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)

Archives contains:

custom-recovery_mx4_philz - custom recovery philz touch 6 for MX4

custom-recovery_m1note_philz - custom recovery philz touch 6 for M1 Note

gscript - folder with unlocking script

patched-stock-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-stock-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

terminal emulator - easy terminal emulator

UNLOCKING PROCESS:

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) VERY IMPORTANT!!!

**************************************************************** (Android 5.0/5.1 firmwares uboot not patch)

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

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!!!

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!!!

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

Create a folder with name "UNLOCK" in phone root directory (SD card)(DCIM folders, Picture, Music, data etc.) and copy in already patched loader file "uboot.img" from firmware folder from PC (where we started our patching (unpacked firmware)).

Pack this firmware (on PC) back in archive (using 7-zip/winrar) with name "update.zip" (default flyme firmwares) - could be useful.

Copy a folder "gscript" together with the contents in phone root directory (SD card).

Install "terminal emulator" on your phone from "gscript" folder.

Open terminal and write

su

sh /sdcard/gscript/unlock.sh

*Important!!* Wait 3 minutes for script action

Reboot your phone by command reboot . If it succesfully boot - congratulations, all right.

Further:

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

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).

You can flash custom recovery - and use it for your needs.

*CARE!!* DON'T try to flash stock meizu firmwares from any custom recovery, we have patched stock recovery for that.

ALWAYS DO A BACKUP!!

VERY IMPORTANT Notes:

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.

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.

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