Unable to boot

[fhendrikx]

Hi,

My TB-X605F was working well, but after the latest updated, it now refuses to boot. It just sits at the Lenovo logo...? Any help appreciated.

Thanks,
Ferry

@fhendrikx
Did you try to reinstall with ubp installer ?

[muskist]

@fhendrikx Same problem here.

Ok so it seems there is a problem with last update !

So we must advertise who is charged of pushing updates to stop it, and revert back to last working image in OTA.
@Luksus @Lakotaubp @AppLee @Flohack ?

@keneda Have asked in Q&A group. Guessing there is only a dev channel for updates?

Guessing too as this device was ported not long ago, and added to installer recently.

No, the device page https://devices.ubuntu-touch.io/device/x605/ says both rc and devel.

I'm pretty sure my device was/is on rc.
Which is strange because the above device page says that devel was updated yesterday.

[Luksus]

The latest update went well for me on my X605L.

Was the device connected to a power cable or docking station while rebooting?
In this case, take it out / pull the cable, try to turn it off with long press on power button and try a restart.

If this does not help, boot into fastboot, connect to pc and type in terminal: fastboot continue.
If that is still not enough, disconnect and turn it off again.
Then boot into recovery and from there hit reboot again.

If it is still not booting, try reinstalling with ubports installer + bootstrap option.

This device can be very picky about reboots. There where times were it didn't want to boot for me either, but then after X attempts it magically did work again.

Besides that, I currently encounter strange reboots on starting unity8/lomiri in devel. First only on the FP3, now I've had it on the X605 too.
The unity loading screen is visible, at some point the dots stop moving, the display goes black and then it reboot automatically... But that seems to be a different issue.

Hi all, worked perfectly for me. Yeah, it boots into scaled mode and not desktop. I did charge it up to 90% and unplugged the power cable. I have found with this tablet and a lot of other devices is to be patient on reboots - it can take some time.

Doesn't work. Only "Lenovo" splash screen.

If this does not help, boot into fastboot, connect to pc and type in terminal: fastboot continue.

Doesn't work either. Says

$ fastboot continue
Resuming boot                                      OKAY [  0.006s]
Finished. Total time: 0.006s

but "Lenovo" splash screen remains.

If that is still not enough, disconnect and turn it off again.
Then boot into recovery and from there hit reboot again.

Same result.

Recovery lets me view a file named /cache/ubuntu_updater.log. Shows an number of error messages. Is this of interest?

[Luksus]

@muskist yes sure, please show the logs.

[muskist]

@luksus
Will do later. Will have to copy by hand.

[muskist]

@luksus

Hope it's readable.

UBports Recovery -> View logs -> /cache/ubuntu_updater.log

[Luksus]

@muskist hm, looks like there was an rc update, but I did not know that a new rc was already released.

I think your best option would be, trying to reinstall using the ubports installer and choosing the dev channel and bootstrap option.

@luksus
Just upgraded my TB-X605F on devel channel and all went smoothly.
Re-booted without a hitch.

[fhendrikx]

@keneda Thanks.. I've gone through UBports installer and it finished the update, and is now booting again.

[Keneda]

@fhendrikx
Wich channel ?

[Lakotaubp]

Not 100% sure this is for this issue but seems to be. From Alfred in Q&A group

"Same happened to the JingPad. The problem seems to stem from the fact that GSI ports overlay device-specific changes to the rootfs in a horrible way compared to traditional ports. GSIs do that at install-time of the update, meaning the rootfs-tarball can trump the device-tarball's contents.

Traditional ports on the other hand overlay changes at runtime, on the fly during boot"

[fhendrikx]

@keneda It's on RC

[muskist]

Succeeded installing rc using ubports installer.

Only one problem when adb didn't see the device after booting to recovery. Worked out at the second try.

Improvements:

• Lomiri starting into staged mode
• Immediately switching portrait/landscape mode when rotating the device. Was reacting kind of sluggish before
• Display going dark immediately after pushing power button as opposed to before when it took about 5 seconds

Thanks @luksus!
