How to install Ubuntu on Meizu Pro 5 that was originally with Android?

or to be more correct, mixed with this

I was able to install ubuntu OTA11 using this tutorial. I did not read the articles from (4.) here is what I did: 1. unlock using xda links 1-3, press home-power-down for recovery mode TWRP 2. copied via USB all ubuntu OTA-11 files to TWRP folder. 3. Installed everything as said 4. unpacked not using tar -vxf but just tar -xf /sdcard/TWRP/… (10x times faster), reboot! – grandrew Jun 28 at 20:50`

Now I have ota-11, but I would of course like to update, and as it says here, it's possible

For those interested in OTA updates – in this method you should do it manually. Ubuntu will download OTA files to /cache/recovery. You need to manually unpack them. After you tap "install and reboot" in ubuntu updater – system will boot into custom loader. Mount system and unpack new files using tar as said in main post using advanced->terminal. – grandrew Aug 2 at 10:29`

I checked /cache/recovery after I tapped "install and reboot" ,and it was quit a lot of files there.

I am little bit unsure which files I should "tar".

  1. Can I cd to recovery and "tar" there, does it work like that?
  2. It is also tar.xz.asc and tar.xz files there, but I guess tar.xz.asc is some kind of signatur. So if I have understood it correctly, the only files I "tar" in recovery is the tar.xz
  3. Do I only "tar" the 4 as in the guide or do I include image-master.tar.xz and image-signing.tar.xz? If that is the case, in which order do I "tar" them?
  4. It's also some more files there, ubuntu_command, .version, last_log, log, recovery.fstab, storage.fstab Can I ignore them?
  5. When I am done (however it's going to work) can I wipe cache?

I now it was a lot of question, but if it works, at least I have understood a little bit more about the Ubuntu phone and maybe I don't brick it yet 🙂

Best Answer

I can confirm that updating via TWRP terminal works just fine. I have done myself on my Pro5. Just do exactly as you did when installing and only those 4 files. The system will be updated and all data will be kept intact. When finished you can wipe the cache. No need to worry about bricking the phone, not this way at least:-)
