There are TWO methods to unlock your phone, I suggest the new one, which is based on Fastboot mode.

For ODM models, such as 16T, 16xs Note9 and so on, you can use FRP Method to unlock your device FOR FREE!

Notice: All the unlock files you get can be reused, YOU DO NOT HAVE TO REDONATE AFTER YOU RELOCK YOUR PHONE AND WANT TO UNLOCK IT AGAIN. Besides, you are suggested to use fastboot -w to wipe your data manually, or wipe data in stock recovery using the skill mentioned in Skills.

If you have unlocked your device and don't have the unlock file, you can backup your private partition via Backup&Restore Partition Tutorial, which contains the unlock state and serial number. You can restore it to unlock your device later again if you relocked.

For devices newer than 16s, such as 16s, 16s pro, 17 and so on. DO NOT use the old method, or your phone will be locked and won't work on Flyme 8. If you already done this, see the Unbrick tutorial to downgrade!

Here are the links to the two methods and the relock method:

Automatic method

Similar to the fastboot method, but is automatically processed. See https://remoteunlockservice.com/payment.php for details.

New Method(Fastboot)

This method shall work for all MEIZU devices with Qualcomm processor. This method unlocks your phone in Fastboot mode. Below are the steps:

  1. Download the github repository, unzip it to some place you like, then double click on meizublunlock.exe

  1. Reboot your phone into Fastboot mode, connect it to your computer, and make sure your device is detected.

  1. Clike on Create request button, a file named as xxxxxxxxx_req.dat ( referred as req.dat below) will be generated in the same folder that the software is in. Donate US$14.5 or 100CNY or more using the one of following links:

  1. Email your req.dat it to fastrpl@yahoo.com with title starting with DONATE, and attach your transaction number as well as your transaction screeshot. You will get the reply with a file like xxx_res.dat(referred as res.dat below) in about 3 hours. Sometimes the reply will be in Trash, please check it.

  2. Put the res.dat into the same folder as the software, start the software, click on Unlock BL and choose your res.dat file. Notice: YOUR DATA WILL BE WIPED AT THIS STEP!

  3. Here are the successful example.

Old Method(9008)

Here are the steps:

  • Install QualcommHS-USB9008 driver

  • Download the master branch and upzip it and go to the unzipped MZLOCK directory.

  • Reboot your phone into 9008 mode. Usually that is "Poweroff your phone, and hold all Volume keys and connect your phone to computer." or you can see another way in the Skills page.

  • Remember the 9008 port number.

  • Click on generate port_trace.bat, follow the instructions.

  • Donate US$5 or 40CNY or more using the one of following links:

  • Email the generated port_trace.txt file to fastrpl@yahoo.com with title starting with DONATE, and attach your transaction number as well as your transaction screeshot, and wait for reply, you will get your BL.bin and flash.bin in about 3 hours.

  • Copy the BL.bin and flash.bin into MZLOCK, and then click on unlock.bat and follow the instructions.

  • go to stock recovery and click Volume up for 5 times, then Volume down for 5 times to erase your data fully, or the touch screen won't work after unlock.

Relock Method
