Unable to install UBports on MX4 Ubuntu edition

[Stefano]

Sorry to hear that. It's a mystery what's happening to your MX4. I wish I could help, but a I can't.

@Stefano Thanks for trying.

When I was trying to install on my device I tried different cables and ports and nothing seemed to work. Know how frustrating it can be, but you will get there.

Guess you have but have you tried using the SP flash tool. I used it to put flyme on ut mx4 might work for you.

[halucigenia]

@UKPhil Thanks for the encouragement

[halucigenia]

@Lakota I will look into the SP flash tool. Thanks for the advice.

@halucigenia Just curious,coming from flyme,did you go into dev mode,and permit OEM unlock.
Or from UT,switch to dev mode while unplugged then connect and watch that dev page,you should get a window asking to Allow PC to connect,(maybe !!)

[UKPhil]

@halucigenia have a gowith the process that I mentioned and see how you get on. This was the only thing that worked for me after being ready to throw it all in and go down the andriod route.

@UKPhil I can't get the devmode version of MDT to run
I ran
sudo apt update
sudo apt install snapd

I ran sudo snap install magic-device-tool --devmode

snap list
Name Version Rev Developer Notes
core 16-2.28.1 3017 canonical core
magic-device-tool 1.0 289 marius-quabeck devmode

When I run magic-device-tool as my normal user
I get the message "snap-confine has elevated permissions and is not confined but should be. Refusing to continue to avoid permission escalation attacks"

When I run sudo magic-device-tool
I get the message "cannot change profile for the next exec call: No such file or directory"

Looks like snap is incompatible with my kernel
snap --version
snap 2.28.1
snapd 2.28.1
series 16
ubuntu 17.04
kernel 4.11.12-041112-lowlatency

I think snap needs an "Ubuntu supported" kernel.
I will try again when I can reboot into another kernel.

The devmode version of MDT doesn't connect to the phone either.

There must be something wrong in that adb / fastboot are not running on the phone.
Time to give up and just keep on using Cannonical UT until I get a fairphone 2 or something?

[UniSuperBox]

The problem seems to be that USB isn't connecting at all. The MX4 has a notoriously bad USB connector.

You might need to try different ports or cables until you're able to find one that works. Run dmesg -w and plug in the phone. Does anything appear indicating that *hci found a new device?

Same port same cable (MX4 Flyme device now with USB module that was in MX4 UT device)

Now what?

[UniSuperBox]

The device with Ubuntu Touch doesn't seem to be working correctly. See if you can plug it in to a USB 2.0-only port. You can also check if there's anything obstructing the pins in the port.

The goal is to have an output like your Flyme device.

[halucigenia]

@UniSuperBox I have tried it in a USB2 port and it was in a USB2 only port when I ran dmesg -w

The fact that I have switched the USB modules between the devices rules out an obstruction.

It must be a hardware issue past the USB port, or a software issue on the UT device.
