can't reinstall Ubuntu touch on MX4 Meizu-Ubuntu edition

@guyhighlander
Ubuntu 15.04 is an old version of Ubuntu Touch. Do you have the release made by canonical ?

Then you have to run the installer on your desktop.
From your previous post I'd say that the installer is OK, now you just need to be able to connect your phone using ADB.
If you already have an older version of Ubuntu Touch I'd say that you have the bootloader unlocked.

Now what does adb tells you when you run adb devices ?

The usb connection on the MX4 is a nightmare. Try lots of usb cables and ports and when you get a connection tape it down, both the phone and cable !!!

adb detects the phone : adb devices

daemon not running; starting now at tcp:5037
daemon started successfully
List of devices attached
75HABM3QVHRX device
but the installer doesn't detect it ,have to do it manually and after running the installer got same problem,like always
phone will be not detected in recovery mode.

Quick tip, have you tried to switch to Devel or RC channel then revert back to stable ?

Switch to another channel don't work.

The file not found error might indicate a data corruption on your phone and no other attempt to download it again.
I don't know how to check the eMMC memory integrity but the "FILE SYSTEM ERROR" made me think that it's likely a data corruption or FS corruption.

It looks like a bigger problem

Try this, phone not connected to PC, boot it in recovery mode, then plug to PC and do the "adb device" command.
If device not listed, this is an ADB driver issue.

On windows (see my own mx4 issue topic link i gave you above) i had an issue with ADB driver, i had to "attach" the driver for MX4 on each boot mode, normal mode, recovery mode, and fastboot mode.

@stefwe Maybe you should create your own topic in order to not interfer with OP problem as it's not the same.

guyhighlander

just booted in recovery mode and adb listed the device, when running the installer its always lost connection until "preparing system",by the way tried both on Ubuntu and Solus Linux.

just organized a new original meizu USB-cable and same problems like all the other ones,even different Distros and PC doesn't help, guess have put my meizu 4 in book shelf and wait for any solution or new update for the installer, thanks for helping anyway

I had similar problems trying to install on Oneplus 1 and followed the same recommendations for new cables without success. I suspect the problem is actually the socket in the phones that is damaged.

AppLee

That's a shame, but yes I guess hardware problems are often the case when all frequent solutions are exhausted.

cliffcoggin

It's easy to see how the sockets can be damaged if there is any strain on the cable during charging. The power connections may be unaffected yet the data connections are bent. I only charge mine wirelessly nowadays to avoid that possibility.

guyhighlander

Hurra Hurra,finally managed to install it with an old laptop with antix linux on it,including deb file for ubports-installer, adb and fastboot and my new original meizu usb-cable.
in the beginning doesn't work ,stuck on transferring data.Than changed channel to rc and everything works fine,took some time but finally its showing up on my MX4. not bad for an old man with no skills in PC,Linux and phones,but forum helps a lot and with copy and past most of I can do....
Thanks for helping

Glad you succeeded :grinning_face_with_smiling_eyes:

Well done, my MX4 is still stuck on Canonical Ubuntu Touch. I will have to have a go with antix linux.
