@w0lf3n Ok first thing enable developer mode on the OPO. Allow usb debugging, MTP and make sure the bootloader is unlocked (though the installer may do this for you). You need adb and fastboot installed on Mint. Then choose the wipe option in the installer if you have nothing on the device you want to keep.

Hi,

I tried that but the installer is not detecting the phone.

The USB tethering is not working.

@w0lf3n with the device connected to the pc/laptop type adb devices in a terminal. What do you get? Watch out for an allow connection message on the device if you have not done that already.

What am I looking for?
I see a lot of words.

Lakotaubp

@w0lf3n In the terminal type

adb devices

It should then say something like

Starting daemon on ---
daemon started

Then it should hopefully list your device.

w0lf3n

@Lakotaubp

No devices listed.

Lakotaubp

@w0lf3n Ok now type

adb reboot bootloader

That should then reboot the device bootloader, look for lock state. You need it to be unlocked. If it is not then type

sudo fastboot oem unlock

Then reboot the device.

w0lf3n

@Lakotaubp

daemon not running. Starting it now on port 5037
daemon started successfully
error: device ' (null)' not found

Sudo fastboot oem unlock
Waiting for device.

Lakotaubp

@w0lf3n Did you first run

adb reboot bootloader

Then if the device lock state is locked, run

sudo fastboot oem unlock

Yes, I did.

On the phone, the USB tethering is not working, it won't switch on. I don't know if that is causing the problem?

@w0lf3n Installed UT by the installer on OPO always gave me problems, but never on the command line.
If you can't do it through the installer, I suggest you to try this simple procedure:

put the OPO in fastboot mode;
Plug the OPO into the laptop;

Run the command line under the terminal (copy and paste the following)

sudo ubuntu-device-flash --server=https//system-image.ubports.com touch --device=bacon --channel=ubports-touch/16.04/stable --bootstrap --wipe

Let the procedure go until UT is installed on the OPO, this should take some time.

@w0lf3n When booted back into the existing os does the phone work ok. When connected to your pc/laptop and the screen unlocked it should show as 'android device' in your file system and you should be able to access the OPOs file system. You need MTP mode for that.

@Lakotaubp

Phone works OK in original OS but computer doesn't recognise the phone. Tethering won't work.

Lakotaubp

@w0lf3n If you are trying with the USB tethering option, that is not the option you want. You need File transfer option, can't remember if that isexactly what it is called or not but not usb tethering.

I'm selecting mtp file transfer but nothing is happening.

Lakotaubp

@w0lf3n Now you have that option retry typing (with the phone in normal mode)

adb devices

in a terminal. What do you get.

I'm relying on the Snap version of the installer on the laptop but maybe it's not vital BUT :

I suggest you to try things IN THIS ORDER in your LInux Laptop IF this has not been the case :

DON'T START THE INSTALLER RIGHT AWAY...
put your phone in developer mode (I think you've already done it);
plugging in the phone;
type adb devices in terminal : your phone should be listed and detected (i hope !).
NOW, LAUNCH THE INSTALLER and follow the installation procedure.

And if it's doesn't work, you can always try the command line procedure i gave you.

Good luck !

@domubpkm

Tried both methods and neither work.
My phone doesn't show in terminal.

@w0lf3n The cable could be at fault here too. Based on your comments this is completely unrelated to the UBports installer but you'd find the same problems trying to install any Android ROM too.

So, the questions are:

Can you use the cable simply to transfer files to/from a phone? Does it work and does the transfer succeed?
Can you try a different USB cable? Some have issues with this - usually the longer cable the worse it can get.

@zubozrout

No, the computer is not recognising the phone and I have tried 3 USB cables so far.
