How to Update Meizu MX4 with CM 12.1 Android 5.1.1 Lollipop Custom ROM

Meizu MX4 is coming with decent to high end hardware specifications, but the software support is not that great. In that respect, most of the MX4 users are still stuck on KitKat, while others are currently experiencing the already outdated Jelly Bean platform, even though some Lollipop OTA have been released in limited markets only. So, probably you are trying to find a stable and smooth Android 5.1.1 update for your Meizu MX4.

In that case, you can now use this dedicated step by step guide where you can learn how to install the CM 12.1 custom ROM on your own Meizu MX4. This version of CyanogenMod is based on stock Android 5.1.1 Lollipop OS and has been optimized and customized especially for your MX4. However, this CM12.1 release is not coming straight from CyanogenMod, so we are not dealing with an official built of the already mentioned ROM.

In fact, this release is supported by those of xda-developers – we should thank them for this step by step guide. Therefore, this CM 12.1 firmware is only a ported CM version that comes to update the Meizu MX4 to latest Android 5.1.1 Lollipop OS. However, according to those who have already tested it, the ROM works without major problems, though some minor bugs have been reported lately – anyway, you can safely install the CM12.1 system if you are planning to make this ROM your default one (on a daily basis, the Android 5.1.1 Lollipop OS can be used without lags, bugs, hangs or other similar software related issues).

Since the CyanogenMod ROM might come with minor problems, before updating your Meizu MX4 with this Android 5.1.1 Lollipop firmware, you should make a Nandroid backup. Through this operation you can save (and restore when needed) the current ROM that powers your Android device, without having to apply another dedicated and risky update or downgrade operation.

CM 12.1, as a custom ROM, can be installed only in certain situations and conditions. In that respect, you first have to unlock the bootloader of your Meizu MX4. Moreover, after taking care of the bootloader aspect you have to root your Android device for unlocking the internal system – the Lollipop ROM will have to access, modify and optimize the Android OS that runs on your phone. Finally, on your Meizu MX4 you have to install a custom recovery image such as CWM or TWRP recovery as the custom ROM is provided in form of a .zip firmware file.

It is important to know that with CM12.1 installed, your Meizu MX4 will run better and faster. Also, the battery life will be upgraded, new features that cannot be found on the default Android 5.1.1 system will be flashed and the basic Lollipop UI will be customized and optimized. However, everything comes with a risk: you will void the warranty of your device once you start to apply the steps from below – CyanogenMod is a custom ROM and not an official OTA update, so this Lollipop release shouldn’t be associated with Meizu or with Google.

Do note that if you will brick your Meizu MX4, you won’t be able to reclaim its warranty when taking it back to service – most likely, you will then have to pay for the technical assistance. That’s why, at this moment you might want to check how to manually fix the most common Android related issues.

While installing a custom ROM you have to make a hard reset and clear cache on your Android device. If you skip these processes, then the new Android system will not run properly on your phone. So, considering these aspects, before starting the update procedure from below, you need to backup your Meizu MX4. The backup can be easily applied (through Google Play apps, cloud storage platforms and so on) and you can easily save different type of info such as images, videos, audio files, contacts, call logs, text messages, internet setting, IMEI / NVRAM, market apps, calendar info, saved passwords and lot more.

Other general pre requisites must also be considered; in that respect read and follow:

  • A computer must be used as on the same you will get the CM 12.1 firmware file.
  • Temporarily turn off security protection from your computer – else, the download process might be interrupted.
  • Your phone and its USB cable will also be required.
  • Install the Meizu MX4 USB drivers on your computer.
  • On your smartphone go to “menu – settings – about phone” and tap several times on Built Number for gaining Developer Options.
  • Then, also from your handset, check the USB debugging option – this feature is located under “menu – settings – developer options”.
  • Charge your smartphone if the battery status is showing less than 50% power left; if you skip this process then your phone might get turned off, and possible bricked, during the installation process.
  • The Android 5.1.1 Lollipop custom ROM is compatible only with the Meizu MX4 variants or so try not to mess things up.
