This is a quick guide for how to reflash
Fyme OS
on Meizu MX4 Ubuntu Edition. Flyme is based on Android with some
redesign along with extras. It doesn't ship with Google apps, but those
are easily installable.
You can flash Flyme 5.1.12G or 6.1.0G (released recently), both based on Android 5.1. To see what's new in Flyme 6, check out
THIS
page. Using the steps below, you should receive future Flyme OS updates
automatically, so there's no need to reflash anything manually for any
OS updates.
Flash Android (Flyme) On Meizu MX4 Ubuntu Edition)
Before proceeding, make sure your phone is
charged. Also, like with any flashing procedure, this may brick your
device, so use these instructions at your own risk! And finally, I
should mention that I didn't yet try to perform a reverse procedure
(install Ubuntu Touch back) so if you plan on doing this in the future,
you'll have to figure out how to do it yourself. What you'll need
1.A. adb and
fastboot.
In Ubuntu,
adb and
fastboot are available in the official repositories. To install them, use the following commands:
sudo apt install adb fastboot
These can also be downloaded from HERE (for Linux, Mac and Windows).
1.B. Flyme firmware (global version).
The Meizu MX4 global firmware is available to download from HERE.
1.C. recovery.img from Flyme OS.
This can be downloaded from HERE or HERE.
Place the firmware along with the recovery image in your home folder.
2. Enable Developer mode on your Meizu MX4 Ubuntu Edition (About phone > Developer mode).
3. You may encounter an error with
adb /
fastboot not detecting the Meizu MX4 Ubuntu Edition device. To fix this, open the
~/.android/adb_usb.ini file with a text editor (if it doesn't exist, create the ".android" folder in your home directory, and a file called
adb_usb.ini inside this folder) and paste the following in this file:
0x2a45
... and save the file.
On Windows, this file is available under
C:\Users\\.android
4. Flash the recovery and Flyme OS
4.A. Connect the Meizu MX4
Ubuntu Edition device to your computer via USB (USB 2.0 is recommended
because it looks like there might be issues with USB 3.0), then reboot
in bootloader mode and flash the recovery:
adb reboot-bootloader
fastboot flash recovery recovery.img
Note that the phone must be
unlocked when doing this. Also, the first time you use adb, the phone
will ask if you want to allow the connection - make sure you click
"Accept"!
In theory, you should be able to reboot to bootloader by holding volume down + power buttons, and into recovery by holding volume up + power,
but these didn't work for some reason on my device (I don't remember if
only one of them or both), that's why I used commands instead in this
article.
4.B. Next, power up the phone and after Ubuntu Touch boots, run the following command to reboot into recovery:
adb reboot recovery
From the recovery screen (which is in
Chinese), you need to get to a screen which displays the "adb sideload"
command at the bottom. You get to this by selecting the various options
in the recovery screen, but unfortunately I forgot which one (and I
didn't took a picture). So unfortunately I can't tell you exactly how to
get there, but remember that "adb sideload" should be displayed at the
bottom when you get to the right option.
Once you get to the screen I mentioned above, run the following command
