MX4 Ubuntu Edition: FAILED (remote: unknown command)

jamieweb

@AlainW94 Thanks for this. Will it prevent me from having to do the restore to the original Canonical UT like @Lakotaubp has detailed? Or do I still need to do that, and then patch ubports-installer with your code afterwards?

AlainW94

@jamieweb Good question, I don't know why we have to step first into the installation of Canonical version. If I was you (easy to say), I tried first to flash the ubuntu recovery, then I start the phone on it, and try to use ubports-installer, if that works, you have gain a lot of time, if not.... You will have to reinstall it. During my issue with my IMEI, I played a lot with the phone by switching between Flyme and UT, all the time, the only thing I did was to flash the ubuntu recovery, start on it and run the modified ubports-installer to get UT back (without having to re-install the original Canonical first).

Lakotaubp

@jamieweb Don't take this as gospel but Flyme has a locked bootloader you can't get in. UBports is not a standard ROM you need UBports Recovery for the installation so you cannot just flash it. You need the original UT first or UBports will not install on the MX4. As far as I know you will not have any insecure/untrusted stuff left. That is what UBports is after all. Safe and secure. The exact technical reason for this method is above my knowledge.
I did exactly what you have UT to Flyme back to UT then to UBports UT using the tools mentioned.

Please someone correct anything that is wrong in what I have said.

jamieweb

@Lakotaubp Ok thanks, I'll see if I can give this a go tonight. To confirm, once I've done this, I won't have to do it again as long as I stick with UBports?

Lakotaubp

@jamieweb Yes that's right, but once you've got UBports you will not want to change

jamieweb

@Lakotaubp That's the idea! Will this also resolve the FAILED (remote: unknown command) issue?

I think I'm actually going to try @AlainW94's modified code first, as as far as I can tell it seems like ubports-installer is just trying to reboot the phone into recovery, but Meizu phones don't support that in the way it's trying to do it.

Exactly

@AlainW94 Just as a side note before I move forward with this - is there a way to download the source for a snap package, a bit like apt source? Or should I just pull it from GitHub?

AlainW94

@jamieweb pull it from github, here are my personal notes when I did it :

git clone https://github.com/ubports/ubports-installer.git
cd ubports-installer
npm run-script dist:linux
./setup-dev.sh
npm start

@AlainW94 Awesome, this has worked! I'm in Ubuntu Touch setting it up now! Thanks for your help, I thoroughly appreciate it.

AlainW94

@jamieweb Awesome ! I'm happy for you.

@AlainW94 Now I'm working on being able to use the device without using the lock button (https://forums.ubports.com/topic/2462/ut-on-meizu-mx4-without-using-physical-buttons/15). Just set up adb shell and monitoring dbus for the right commands to lock+sleep the phone using a launcher icon rather than the physical button.

Also @AlainW94, I'm working on a blog article about my whole UT setup experience. Would I be OK to include a section on your ubports-installer code change? I will give full and clear credit with your name, Twitter, own blog, whatever you want.

AlainW94

@jamieweb Of course, no problem at all if that can help other people experiencing this with their Meizu If you need help for your script, please post in your original thread and I will try to help you. Good job.

Lakotaubp

@jamieweb Glad it worked for you. Well done. Very interesting please let me know when your blog is ready i would like to have a read and thanks @AlainW94 for your input too.

AlainW94

@Lakotaubp My pleasure

jamieweb

@AlainW94 I'm just working on my article now. Which credit would you like me to give? Do you have a website, Twitter, etc that you'd like a link to? As well as a link to your forum profile?

AlainW94

Hi @jamieweb I don't have twitter or a website so you can link my profile if you want. Many thanks to you and of course, I'm curious to read your article

@AlainW94 @Lakotaubp Hi, the article is now live!

Thank you all for your help, I thoroughly appreciate it!

AlainW94

@jamieweb Nice article, it is clear and easy to understand. Thanks for your feedback and the mention !

Lakotaubp

@jamieweb Thanks Jamie good article, should prove very useful and helpful. Couple of very small things with my Ubports hat on that you are probably aware of, one that the UBports foundation is not yet incorporated into German law and that other versions of the installer are available https://github.com/ubports/ubports-installer. That aside once again thank you for your time and effort in writing the blog really enjoyed it.
