[GUIDE] Unlock Bootloader, install TWRP & install custom rom (Mokee) for Meizu Note9

Your warranty will be void.

I am not responsible for any damage on your device.

In this guide I want to show you step-by-step how to unlock the bootloader and install TWRP and a custom rom (in this case Mokee) on your Meizu Note9.

I tried it with global version but it should walk with chinese version too.

This guide is based on the YouTube video from 老婆没米了 (https://www.youtube.com/watch?v=TPESF2A9_ek&t=369s) and the github from sukana (https://github.com/sukanka/MEIZU16S_unlock_tutorial/wiki/Guide-to-Unlock-Your-MEIZU-Device)

Some background:

Normally to unlock the bootloader you have to enter developer options and activate USB Debugging and OEM unlock (since Android 5.0). Meizu hides the second option from their settings. To activate it we have to change this value inside the firmware. The frp section contains this value so we need to change it in there. To do this we use the Qualcomm Flash Image Loader (QFIL). QFIL is an application that helps to flash stock firmware. We will use it to flash our modified rom with OEM unlock activated. Note that you have to deactivate wifi and unplug ethernet cable while use QFIL to prevent issues with the Qualcomm driver.

After we unlocked our bootloader we can install custom recovery like TWRP. With this tool we can easily install custom software to our phone like custom roms or root the device. We install the recovery by booting our phone to bootloader and flash the TWRP image. This will be done by the adb and fastboot platform tools.

Prepare your PC/Notebook:

0. Download and install the required software

Unlock Bootloader:

Enable Developer options

Go to "Settings" -> "About Phone"

Tab on Build number several times until it says that you are developer

Enable USB-Debugging in Developer options

Go to "Settings" -> "Accessibility" -> "Developer options"

Switch on USB debugging

If you see something like "OEM unlock" in Developer options enable it and go to step 18 of this guide otherwise continue with step 4.

Power off your phone

On your PC/Notebook turn off wifi and unplug the ethernet cable to prevent problems with the qualcomm driver

Start QFIL (installed with QPST)

Press the Volume up and Volume down buttons on phone (NOT the power button) and connect it with your PC/Notebook, hold the buttons until QFIL shows something like "Qualcomm HS-USB QDLoader 9008 (COM3)" on the top of the app

In QFIL go to "Configuration" -> "FireHorse Configuration" and set the configuration like shown in this image and click "OK":

Now choose on "Flat Build" and set the "Programmer Path" to "prog_firehose_ddr.elf" of your downloaded firmware

Click on "Load XML ..." and choose the "rawprogram_unsparse.xml" of your downloaded firmware and select patch0.xml in the next window

Go to "Tools" -> "Partition Manager" and agree by clicking "OK"

In the next window search for the label "frp" and rightclick on it

Choose "Manage Partition Data" and click on "Read Data..."

Now open your windows filemanager and go to "%appdata%\Qualcomm\QFIL" and open the folder with the name samething like "COMPORT_3"

Copy the .bin-file and rename it to "frp.bin"

Open "frp.bin" with a HeX-Editor and change the last position of "0007FFF0" from 00 to 01 like this:

Alternatively

you can upload "frp.bin" to https://frp.xingrz.me/, follow the instructions on the website and download the resulting "frp-unlocked.bin"

Go back to the open QFIL window and click "Load Image ..." and choose the above edited file

Close the open QFIL windows

Restart your phone into bootloader by pressing Volume down and power button (this may take some seconds)

Start the windows command line tool (cmd) and navigate to your adb and fastboot directory

Enter the following:

fastboot devices

if you see some output of numbers and characters you can go on, otherwise there is something wrong with the installed device driver.

Enter the following:

fastboot flashing unlock

On your phone choose "UNLOCK THE BOOTLOADER" by navigation with Valume down and enter with power button

Now your bootloader is unlocked and you can install a custom recovery, install custom rom or something else.

Install TWRP:

Boot your phone in fastboot mode by pressing Volume down and Power button

On WIndows start "cmd" in adb folder

Enter the following:

fastboot flash recovery $PATH_TO_TWRP

there $PATH_TO_TWRP is the path to the TWRP image file

On the phone choose "Recovery mode" by navigation with the Volume buttons and enter with Power button

The phone reboots automatic three times and you will see TWRP (chinese and english language support)

Now you have installed TWRP custom recovery on your Meizu Note9. Install custom rom and other things are quite easy until now.

Install Custom Rom (Mokee):

Boot into recovery mode and wipe all data

Download the .zip-file for the custom rom (on PC/Notebook)

Optionally: Download OpenGApps, Magisk and other custom apps

Copy all files on the phone via USB connection

In TWRP go to "install" and choose the custom rom .zip-file (for Mokee: first the RADIO...zip and then MK...zip) and confirm installation

Redo this step for every .zip-file with additional apps (like OpenGApps or Magisk)

Restart your phone

Congratulation! You have successfully installed a custom rom on your Meizu Note9.
