@jenkins47300 Oh my God!!. I'm sorry. Good luck with Nexus 5.

@jenkins47300 Ok. Luck!!

@jenkins47300 Only works from Ubuntu 16.04

@jenkins47300 Have you install all?

sudo add-apt-repository ppa:ubuntu-sdk-team/ppa
sudo apt-get update
sudo apt-get install ubuntu-device-flash
sudo apt-get install phablet-tools

Do you check with adb to detect your mobile?

@jenkins47300 I do not know how to explain it to you. I first put my phone in developer mode (system configuration/about this device).
Connect the phone to the computer and power on + volume up (you are in fastboot now) and select recovery mode.
You may not see any change. Install adb and check that the mobile detects :

root@sku:/home/sku# adb devices
List of devices attached
0123456789ABCDEF offline

Now you can open your Magic Device Tool.

@jenkins47300 You can't put it in recovery mode?. Is your phone Meizu MX4 with Ubuntu Phone?

OK, this screen is Recovery mode
With adb devices detected meizu

root@sku:/home/sku# adb devices
List of devices attached
0123456789ABCDEF offline

But when i'm istalling no.
How i can put my phone online?

I haven't recovery mode (power on + volume up) in my Meizu.

With power on + volume down i have fastboot, but when i push to have recovery mode
only have a screen with Meizu logo and powered by Ubuntu.
