Meizu pro 5 From ubuntu OTA15 to last ubports

pgp

Hello -all,
I installed ubuntu 15.04 on a Meizu pro 5 Flyme 64 Go, years ago with this method :
https://forum.xda-developers.com/meizu-pro-5/development/tool-ubuntu-touch-installer-t3469304
Now I'm interested to migrate to the latest stable UbPorts release.
Can I do that just changing the repositorys in the phone?

Lakotaubp

The pro5 is on the installer now try that first.

pgp

thank you @Lakotaubp, for development, (the short story). I tried the installer UBports Installer 0.4.14-beta. First time it failed to flash the microcode with fastboot. I tested adb : I see the device, I log in a terminal. But fastboot don't see any device. Test done after :

$ adb reboot bootloader

After that the meizu Ubuntu boot screen appear (like @ every reboot).

But the "fastboot device" command executed in root don't show anything. Even after the command :

fastboot oem unlock

So, I tested without the option "flashing the microcode" and the installer said "OK it works" but the phone screen said approximatively "error, contact meizu", in several languages. The phone reboot with no issue on the older UbuntuTouch sytem like nothing happens.

First time I installed ubuntu, (phone was flyme) it was with a script found on a forum, ~~I don't still have~~.

Here is the code :

A question is : If it works a first time, It means my phone must be international and fastboot unlocked? No?

So I will try to investigate why fastboot don't see my device.

Lakotaubp

@pgp Remind me what OS you are using on pc

pgp

@Lakotaubp I use ubuntu LTS and debian, but under my debian (buster), ubports-installer don't works.

pgp

I still don't understand why is my fastboot seems locked. I hope I'll don't have to re-install flymeOS to unlock that.
I maye just don't have the good drivers on my laptop : I just install adb and fastboot like this :

# apt install fastboot adb

Same result after :

apt install android-tools-adb android-tools-fastboot

Any idea?

pgp

Maybe a indication here : https://forum.xda-developers.com/meizu-pro-5/development/recovery-twrp3-0m86patchedst0rm77-t3469296/post68868682#post68868682

In the end they write :

Warning:
** If you flash an official update.zip from Flyme, remove bootloader, ldfw & recovery from ZIP*
** Otherwise you'll find yourself with a locked bootloader ** *

If it is my case (I don't remeber the details of my first ubuntu touch istall) It means I'm fucked ?

Sounds like your PC is not seeing fastboot, are you using sudo for all fastboot commands

Could you put an earlier unbuntu in a VM or on a thumb drive.

I had an Android device recently , win 10 would see Adb but not Fastboot, had to switch OS's in the middle of it ( to Deepin)

pgp

Thnk you @Marathon2422 . Yes all commands are done with root on debian (buster), and sudo su on ubuntu (18.04 LTS).
Next step, I think I will try this from this post : https://forums.ubports.com/topic/2755/meizu-pro-5-flyme-os-to-ubuntu-touch-modem-update-fingerprint-function

**Step 1:Unlock Bootloader
Download: https://drive.google.com/file/d/1SpPqSFQ0b7thvs_f2VqexDxQTBK6bQP5/view?usp=sharing
Rename to update.zip and put inside your device storage.
Rebooot to recovery pressing Volume up + Power and choose "System Upgrade"
Unlock Bootloader 2nd Method: https://drive.google.com/file/d/1U09dVhiBJebPMwQ1q99R2RzBC8hErLuI/view?usp=sharing
Just rename the file to update.zip put in your internal storage go to recovery and update.
Now your device has an unlocked bootloader.

Step 2: Flash TeamwinRecovery
Download: https://drive.google.com/file/d/1T30ug5TQqzRxZiKsFk3IhpR5c218N4Pc/view?usp=sharing
Reboot the device to fastboot pressin Volume Down + Power
Open a terminal and do the command:

fastboot flash recovery TWRP_3.0_m86.img*

@pgp You would need to resize the .cache partition on your phone. It's too smalll to contain all the files needed to flash 16.04
Search Increase Cache Partition on this forum, you'll find the answers.

Official Ubports won't work, install it with ubuntu-device-flash from Terminal.

Edit: also need to remove all files from .cache/recovery as it is now full of files from unsuccessful instalation.

@Stefano Thank you for the advice. I'll try asap.
