Ubuntu phablet-armhf image does not boot on Asus TF101

[Carla Sella]

I downloaded http://goo.im/devs/jholtom/ubuntu-touch-tf101.zip and http://cdimage.ubuntu.com/ubuntu-touch-preview/daily-preinstalled/current/quantal-preinstalled-phablet-armhf.zip.
I flashed the ubuntu-touch-tf101.zip and then the quantal-preinstalled-phablet-armhf.zip files to my Asus TF101, but after reboot I only got a black screen.
Tried twice, cancelling cache and wiping data, but it just gives me a black screen after reboot.

[Julius Berger (julius-berger)]

Same problem here. Just a black screen...

[Steve Williams (steve-fi)]

I thought I'd chime in too in the event that something I submit helps.

I've installed 3 different versions of Clockworkrecovery mod (5.0.2.0, 6.1.0.0 and 6.0.2.0) and tried to flash Ubuntu Touch (build 0.5) as per the instructions on both the Ubuntu wiki page and the ones on XDA developers.

Tried flashing with: wipe data > cache > dalvik > install base > clear cache > install phablet > clear cache > reboot; still doesn't work.

My backlight comes on, I can adb to the tablet and communicate, but I am not 100% sure on how to get logging from it (if someone can explain, I can post logs). I can press the power button to get the backlight to go off and on.

The HDMI port works, but does the same as the tablet screen (backlight goes on and off depending on if I hit the power button on the tablet).

Tried with the dock connected and disconnected. Same results. Tried different MicroSDHC cards and this didn't make any difference either.

[Parthi (parthibaraj)]

Even I'm observing the same Issue.
Flashing is successful. But only black screen is displayed.
Even after multiple reboots same behaviour is observed.

[Ayrton Santana (ayrton)]

Confirmed. I will try to fix that.

[Jacob Holtom (jholtom)]

if ya'll can get me a logcat by running something along the lines of
adb logcat > logcat.log and then posting the logcat.log file somewhere along with
adb shell; in the shell run dmesg > dmesg.log and then post that file after adb pulling it.

[Parthi (parthibaraj)]

Same Issue is observed in ubuntu-touch-tf101 (version 0.1) also.
Attached logs for both 0.1 and 0.6 versions.

[Steve Williams (steve-fi)]

I've attached both my logs for version 0.6.

[Carla Sella (carla-sella)]

Here are my logs.

[Carla Sella (carla-sella)]

And my dmesg.

[Scott Weldon (501st-alpha1)]

I'm having the same problem here. Flashed with the newest images as of today, after wiping data. My logs are similar to Carla Sella's.

[Ricardo Salveti (rsalveti)]

I/mir::ApplicationManager( 106): virtual void mir::ApplicationManager::binderDied(const android::wp<android::IBinder>&)()283
F/libc ( 106): Fatal signal 11 (SIGSEGV) at 0x00000001 (code=1), thread 106 (ubuntuappmanage)

Just wonder if there might be an API/version mismatch between the ubuntuappmanager and hybris that are built on the android side.

jholtom, can you grab the bzr revision from yours <androidbuildroot>/ubuntu/hybris and <androidbuildroot>/ubuntu/platform-api?

[Scott Weldon (501st-alpha1)]

I tried using the old ubuntu-tablet-tf101.zip images (0.1, 0.2, 0.4, and 0.5), with the same results. Also got the same results with today's build of phablet and the current tf101 image (0.6).

[Jacob Holtom (jholtom)]

Build Server is coming online now, and i'm going to try to rebuild this again with some changes that hopefully will fix it. e.g. update the ubuntu source tree.

[Ayrton Santana (ayrton)]

Changed the status \o/
I will change to the final status when I verify the fix in my device.

[Jacob Holtom (jholtom)]

awesome, thanks for your help.

[Ricardo Salveti (rsalveti)]

I just build the image with the git repos available from the wiki, + latest from phablet and latest from the bzr branches (platform-api and libhybris), and was able to get to a working shell again.

Please make sure you have the latest of everything and it just work just fine :-)

[Jacob Holtom (jholtom)]

i updated the repo, so does the image i uploaded to goo.im work? if not i'll go update all the branches again.

[Ayrton Santana (ayrton)]

Still happening.

[Corasaaa (francesco-corazza)]

Confirm, it is still happening.

[Carla Sella (carla-sella)]

I have tried with: http://cdimage.ubuntu.com/ubuntu-touch-preview/daily-preinstalled/current/quantal-preinstalled-phablet-armhf.zip and http://goo.im/devs/jholtom/ubuntu-touch-tf101.zip but the problem is still there.

[Carla Sella (carla-sella)]

Here are my log files.

[Vincent Gerris (vgerris)]

Same for my SL101 which should be the same.
I used version 0.7 of ubuntu-touch and the daily link above from half an hour ago.
I also get a black screen on boot.

[Jacob Holtom (jholtom)]

Determined problem is not related to our image ATM. Due to NEON added to the daily images.

[Ricardo Salveti (rsalveti)]

Do you know which app might be using neon by default? I was able to get it working here after building the image myself. Will try another respin today with our current image to see if it works better.

In theory Ubuntu should not ship any neon-code enabled by default.

[Jacob Holtom (jholtom)]

Not 100% sure, but we think it is NEON but on the xda thread onkelbebu says differently. but for whatever reason this is the error. Libhybris, and platform-api are latest along with all other repo parts.
The error is: E/linker ( 219): ics/linker.c:1598| WARNING: Skipping libc.so

[Daniel Winzen (q-d-deactivatedaccount)]

This is not just happening on this device, I'm using Xperia Neo V (haida) with the same probems.

[Jose Antonio Sousa (jasousa-4)]

Same on my Xperia Neo (hallon).
Back screen... but its turn on/off secreen with power button.

[Steve Williams (steve-fi)]

Can't post on XDA devs (not got 10 posts), but the update from onkelbebu resolved my Black Screen issues.

Post can be found here:

Thanks onkelbebu!

[Steve Williams (steve-fi)]

Also, the HDMI port works, it doesn't output 1080p, only the same resolution as the Transformer Pad's.

[Carla Sella (carla-sella)]

Today I tried to flash the cm-10.1-20130404-UNOFFICIAL-tf10 and then the http://cdimage.ubuntu.com/ubuntu-touch-preview/daily-preinstalled/current/raring-preinstalled-phablet-armhf.zip files to my Asus TF101, but after reboot I still get only a black screen, but its turn on/off secreen with power button.

[Carla Sella (carla-sella)]

I'm attaching the logcat file.

[Carla Sella (carla-sella)]

and the dmesg file

[Daniel Holm (danielholm)]

Issue is back...
