<![CDATA[Mobian to UT]]>[EN] - Hello everyone

I bought a OnePlus 6T because it has the particularity of supporting Mobian and Ubuntu Touch. I have been using Ubuntu Touch from the start. I have already :

  • Nexus 4 (avec UT
  • Nexus 7 Wifi (avec UT)
  • BQ Aquaris E4.5 Ubuntu Edition (2x)
  • BQ Aquaris M10 FHD Ubuntu Edition

Suddenly, with the OnePlus 6T I had the possibility of trying Mobian. However, but the project is not advanced enough for daily use so I would like to put UT.

The problem is that the phone only gives me the fastboot as if there was no Bootloader or Recovery anymore ... The installation of UT is blocked by what I cannot pass in Recovery mode . All attempts are returned to Fastboot.

I downloaded the OxygenOS .zip (9.0.15) but I cannot install it ...

~$ fastboot devices
3b9e7fd6	fastboot
~$ adb devices
List of devices attached

~$

Can you help me put UT?

Thank you.

[FR] - Bonjour à tous

J'ai acheté un OnePlus 6T car il a la particularité de supporter Mobian et Ubuntu Touch. J'utilise Ubuntu Touch depuis le début. J'ai déjà :

  • Nexus 4 (avec UT
  • Nexus 7 Wifi (avec UT)
  • BQ Aquaris E4.5 Ubuntu Edition (2x)
  • BQ Aquaris M10 FHD Ubuntu Edition

Du coup, avec le OnePlus 6T j'avais la possibilité d'essayé Mobian. Cependant, mais le projet n'est pas assez avancé pour une utilisation quotidienne et j'aimerais donc mettre UT.

Le soucis c'est que le téléphone ne me donne que le fastboot comme s'il n'existait plus de Bootloader ni de Recovery... L'installation de UT est bloqué par ce que je n'arrive pas à passé en mode Recovery. Toutes les tentatives renvoi vers Fastboot.

J'ai télécharger le .zip de OxygenOS (9.0.15) mais je n'arrive pas à l'installer...

Pouvez-vous m'aider à mettre UT ?

Merci.

@Webmust is the one with the issue here, not me! 😉

One of the options I was talking about is probably this one =>

And if none of the above works, MSMdownload Tool at xda-developers will put you back to stock from the factory

I only know existing "roms" for MX4 and BQ devices (very old images from canonical days) and for Volla devices (recent).

I imagine that roms can be done for any device though, but i don't know how to do some, and asked for one UT ubports recent image version (see my thread in MX4 subforum), but did not get one, finally i used installer.

Anyway, try what my fellow forumers told you, that should be fine.

Extract it and then you have to flash each file individually in fastboot. This will put it to the required Android version 9 and then you can flash UT.

Here at XDA-developers will tell you how. If you are using a Windows machine, I highly recommend flashing each file individually as described.

[EN] - Thank you keneda,

Actually, I would like to know where to find the UT image files for the OP6T in order to do a manual install. My first installation of UT was done this way.

For example, for Mobian the manual installation is very simple (https://wiki.mobian-project.org/doku.php?id=install-android) with 2 .img files and 3 command lines

~$ fastboot flash boot mobian-<device>-phosh-YYYYMMDD.boot-<variant>.img
~$ fastboot -S 100M flash userdata mobian-<device>-phosh-YYYYMMDD.root.img
~$ fastboot erase dtbo

I'm not a great technician, but UT must also be manually installable, right?

Is it still possible to proceed in this way? Are there still .img files for UT? If they don't exist, can we create these .img files from source?

As much as possible, I would like to directly install UT without doing all the very complicated process of using the UT installer.

Thank you.

[FR] - Merci keneda,

En fait, j'aimerais savoir où trouver les fichiers image de UT pour le OP6T afin de faire une installation manuel. Ma première installation de UT avait été faite de cette manière.

Par exemple, pour Mobian l'installation manuel est très simple (https://wiki.mobian-project.org/doku.php?id=install-android) avec 2 fichiers .img et 3 lignes de commande

~$ fastboot flash boot mobian-<device>-phosh-YYYYMMDD.boot-<variant>.img
~$ fastboot -S 100M flash userdata mobian-<device>-phosh-YYYYMMDD.root.img
~$ fastboot erase dtbo

Je ne suis pas un grand technicien, mais UT doit aussi être installable manuellement, non ?

Est-il encore possible de procédé de cette manière ? Existe-t-il encore des fichiers .img pour UT ? S'il n'existent pas, peut-on créer ces fichiers .img a partir des sources ?

J'aimerais, autant que possible directement installer UT sans faire tout le procédé très compliqué permettant d'utiliser l'installateur UT.

Merci.

Maybe you should ask on mobian forum how to return on android, i don't even know if you can switch from mobian to UT directly.

Tu devrais demander sur le forum Mobian comment repasser à android, je ne sais même pas si c'est possible de passer directement de Mobian à UT.
