Unable to flash 16.04/devel to Pro 5 Ubuntu Edition

[tomoqv]

I am trying to go from UBPorts 15.04 to 16.04 on my Pro 5 (Ubuntu Edition). I have tried the UBPorts installer as well as command line as follows, but it seems my Pro 5 won't enter recovery.

~$ sudo ubuntu-device-flash --server=http://system-image.ubports.com touch --device=turbo --channel=ubports-touch/16.04/devel --bootstrap --wipe --verbose [sudo] password for tomas: 2018/01/09 08:58:26 Device is |turbo| 2018/01/09 08:58:26 Flashing version 11 from ubports-touch/16.04/devel channel and server http://system-image.ubports.com to device turbo 2018/01/09 08:58:37 Waiting for device to enter recovery mode ... Failed to enter Recovery

When I do [Power] + [vol up] it gives me a purple screen with the Ubuntu logo in the middle. Neither UBPorts installer nor command line boots past the splash screen.
I have tested with different cables and different PCs too. Is there anything else I can try?

I recommend that you start the installer from a terminal window and this way you will see some messages telling you if there is a progress of a download or anything else.

Another of my experiences with the installer is that first the phone has to be booted with power + volume down and then it will say on the installer to boot the phone again with power + volume up. Sometimes it doesn't even say that but I had to try it and it worked.

Today I tried again to flash xenial (16.04) using the installer and got stuck pushing at 42% and then I canceled everything. I think I will wait until the fingerprint will work (https://github.com/ubports/ubuntu-touch/issues/396).

Success!
Thanks for the tip. I started the installer with sudo ubports-installerand it worked!

Wow! Great! What did you do in order to make it work? Just that command and then it worked? And what buttons did you have to press on the phone?

Bad news. After OTA update (I think r15) the phone no longer boots. I reflashed it today, but the problem persists.

How to flash:

1. Put the phone in fastboot mode by pressing [Power] + [Vol down]
2. Connect it to your PC with a USB cable
3. Open a terminal window and launch UBPorts installer with the command sudo ubports-installer
4. Wait for the installer to download files and ask you to boot the phone to recovery
5. Boot the phone to recovery by pressing [Power] + [Vol up] (a dark purple screen with Ubuntu logo should appear
6. Wait for installer to finish
7. Exit installer

I hope they fix it soon... I see there is no new version for today (http://system-image.ubports.com/ubports-touch/16.04/devel/turbo/).

I think I will wait until fingerprint will function (https://github.com/ubports/ubuntu-touch/issues/396) and then switch to xenial.

Thank you for writing down the instructions, very useful...

What you can do is :
sudo ubuntu-device-flash --server=http://system-image.ubports.com touch --device=turbo --channel=ubports-touch/16.04/devel --revision=14

I have done this and installed without any proble;n 16.04 ...
