Xenial rc fails to boot on Meizu MX4

Lakotaubp · 24 Jun 2018, 09:11

@advocatux Just done. Clean install with wipe. Very basic setup. Restarted 5 times. Sometime slow to boot. Hangs on Miezu screen black bar appears at boot then goes and it boots into UBports. Others starts very quick into UBports. So yes after first reboot mine does start.
Is there a wiper button issue on the Miezu? Have to move my finger about at times to get it going.

@lakotaubp what do you mean?

Lakotaubp · 24 Jun 2018, 09:45

@advocatux oh flip spell check madness again. POWER button POWER button. Did I not say I'd fitted wiper blades to the screen: )

advocatux · 24 Jun 2018, 09:58

@lakotaubp lol, okay. I don't remember any specific issue with MX4 power button. Maybe it's a hardware issue in your device?

Lakotaubp · 24 Jun 2018, 10:11

@advocatux Only mentioned it in case it might be causing an issue for @ThePossessor in combination with 16.04. Really have no idea. Can only suggest he tries clean wipe install 15.04 then the same on 16.04 and see how it goes.

ThePossessor · 24 Jun 2018, 20:16

Thanks @advocatux and @Lakotaubp for your answers and tests.

@Lakotaubp Switching back to 15.04 works perfectly each time. I have tried to go from there to 16.04 with wipe many times. The first boot then works ok. After basic setup I do poweroff.
When I switch on again:

I get the meizu logo powered by ubuntu
Am small black bar with a text appears on bottom
button light goes on
button light goes off
small black bar disappears
screen goes totally bright
If this is the first time to switch on, then after ~20-40 seconds the device boots one more time. After this, the boot progress simply stops here at every boot.

I even tried a second MX4 I have access to. It gave the exact same result.

@thepossessor I must admit mine as I said does take a time to start up like yours, but after the bright Miezu screen so far always has.
When the screen appears to hang have you tried pressing the power button down again to see if that will force it to boot up . I've done that once before.
Also I'll check the spec/ build numbers of my Mx 4 tomorrow and let you know so you can check against yours see if there's a difference. It might give us a clue to something.

ThePossessor · 24 Jun 2018, 21:17

@lakotaubp pressing the button again does not have any effect.

Holding it a few seconds switches off again as expected.

Lakotaubp · 24 Jun 2018, 22:22

@thepossessor and if you keep holding after it switches off does the reboot still hang. Mine reboots as normal if I do this after the long bright miezu screen hang.
One last thing try the dev version of 16.04. Not sure if you have, it might just have a different effect.

Lakotaubp · 25 Jun 2018, 05:28

@thepossessor Have put mine on the dev channel and restarted and all went well. The model number for mine is M461

ThePossessor · 25 Jun 2018, 19:22

Holding power button makes the phone power off and then power on again. It does not boot to UI though.

I am already testing dev channel too. No difference.

ThePossessor · 25 Jun 2018, 19:28

Model is "M461 LTE Mobile phone".

Develop channel makes no difference on mine.

Lakotaubp · 25 Jun 2018, 19:34

@thepossessor then I'm stumped sorry different model may well be the issue. I would now post a bug report if you havn't already. If I come up with anything else I will get back to you. Lets hope someone else can shed light on this.
Have you tried the welcome and install group just in case

Sorry I had a typo. It is a M461 too of course.

The forum search did not return anything really valuable.

It is files as bug . I guess I just have to sit and wait.

ThePossessor · 27 Jun 2018, 20:59

I made some further tests by rebooting at different points of basic setup process.
This way I found out that booting is not working anymore after timezone setup.
I then first removed timezone settings with adb shell in the first boot. After this I was able to reboot successfully multiple times.
I then configured a different timezone. After this I could still reboot fine.
To crosscheck I configured the timezone I usually choose. The problem was back,

"Europe/Berlin" works but "Europe/Luxembourg" does not.

Just weird.

Lakotaubp · 28 Jun 2018, 05:00

@thepossessor I wonder if this is linked to calendar and clock crashing? Both crash after putting in settings or account settings. They don't stop the thing booting up though.
Glad you can boot up now are you still on dev. The updates may fix the problem as they roll out.

ThePossessor · 28 Jun 2018, 21:16

@lakotaubp yes I am still on devel channel.

As for the crashing of clock app. It is like most apps on MX4. If they crash when they ask for additional permission then:

Just uninstall it.
Reboot phone.
Reinstall it.
Setting additional permission then usually works.

This behaviour was reported long long time ago. I have no clue why this still is so.

Well actually I am not sure if this is what you meant with clock crashing.

Lakotaubp · 29 Jun 2018, 04:29

@thepossessor it s affecting bq5 as well not tried nexus 5 yet as need working calendar for work. Uninstalling does nothing have tried after each update on dev channel.

ThePossessor · 5 Jul 2018, 14:30

@lakotaubp - it does usually help with crashes that happen when the apps prompt for access to additional privileges. It must be a bug with the app itself in your case. I am not using the calendar much so no ideas on the one. The app starts - this much I can say. ,-)

@thepossessor Hi again just wondering if your startup timezone issue has cleared up now we've had more updates.
