I have tested two different kernels but I think that this is not the problem.

My actual configuration is android kitkat 4.4.2 complete stock , multirom v22 and recovery 2013-12-24. All installed from multirom manager.

When i add the ubuntu touch rom, the install log shows two errors (one for each zip file) regarding /data partition, but the installation says that was successful.

Thanks in advance.

Just to eliminate other factors as your issue.. I successfully got this booted the first or second day it was posted (and it booted almost instantly after install). Since I had deleted it again, downloaded from the same spot and reinstalled. All else being the same (main kernel and rom) i too now am stuck at black screen. Perhaps the download link leads to an automatically updated version which killed support

How to Fix the Black Screen with Ubuntu Touch on the 2013 Nexus 7

Hi everyone!

The official way to fix the black screen after booting Ubuntu Touch for the first time on the 2013 Nexus 7 (flo) is as follows:

Make sure you have Ubuntu Touch booted (i.e. the black screen appears after the Google logo disappears).

Connect the Nexus to your computer via USB (if it isn't already).

From your computer (that has the Android ADB tools installed), run:

$ adb shell
# touch /home/phablet/.display-mir

Ubuntu Touch should immediately appear. If it doesn't, reboot; the Ubuntu Touch lock screen should appear after the Google logo disappears.

Credit to Oliver Grawert (ogra in #ubuntu-touch on Freenode) of the Ubuntu Touch project for providing these instructions to the developers.

Very good test run. It does not stay Running too long before freezing, and I'm OK with that. I bought this tablet for this reason, and had Ubuntu touch in mind when I got it. I'm very willing to wait this one out, a little side bonus I wasn't expecting was the beautiful dual boot addition, like it was meant to be :good:
[Nexus 7 (2013) General] csteene:
I ****ed up

I accidentally flashed the two zip files from the beginning of multirom not in the add another rom section. I think i may have flashed over my stock android and now its not showing up in the rom list, but ubuntu is. The thing is it wont get past the black screen with google. I can boot into my bootloader and into multirom. the problem is i didnt make a backup of android and so now idk what to do. i cant boot anything did i permanently brick my tablet?
[Nexus 7 (2013) General] Government:
can't say they didn't warn you

Did you write down or remember your build # ? The stock ROM is available via Google or on the links provided in the tutorials, right around the same place the warning to backup was located. In a hurry? That's an expensive paperweight if you get in to too big of a hurry. I have bricked a device doing that very thing, now attention to detail serves me much better. Or just temp. Install some custom ROM until you find find which stock one you had. There are hundreds of suitable ROMs for download right here on this site that should be more than enough to get you booting again, pick one.
[Nexus 7 (2013) General] Alucai Vivorvel:
So, the download link for the "armhf.zip" file that's ~458 MB keeps failing, no matter what device I attempt the download on, tablet or desktop computer. Would this be a suitable replacement? I don't think it has the Mir fixes, as it's probably not by the same user, and it's from 01/30, whereas the "~ogra" version is from 02/06.

EDIT: Just realised that this is the same as [MENTION=5699294]paolorotolo[/MENTION]'s link. Never mind!

EDIT again: And that one failed, too. Huh?!
[Nexus 7 (2013) General] mtotho:
Here is the link from the op

http://people.canonical.com/~ogra/ubuntu-touch/

Says its last updated feb 6th but apparently has fixes in it

This is the more or less official link I think

http://cdimage.ubuntu.com/ubuntu-touch/daily-preinstalled/pending/

(The link that has no device specific name,

trusty-preinstalled-touch-armhf.zip)

Its updated nightly (2/19 is latest) but may not include whatever fixes the other one does. In either case they both seem exactly as buggy to me.

Make sure multirom is up to date because the latest update fixed black screen on boot issues

Looks like they updated the small zip on Feb. 7 and the big one on Feb. 24. Just wish they had some kind of up to date change log or a PR dept.

I don't see a daily build with flo in the name.

Is there a tutorial on how to install UT on flo from scratch ? I do see on WiKi main installation procedures, but it's universal syntax. Anyone can write step by step specifically made for flo with latest build available ?

And another think multirom using r206 , is that Feb 6 release or how do they do this numeric thing ?

How did you install the xda app? When I try it asks for my Ubuntu account but the Accounts option in system settings doesn't work for me
[Nexus 7 (2013) General] droidshadow:
about the two files?...

I am so excited about this project!! Thank you so much to the developers who took this project on and got it working?...

Ubuntu Touch was one of the main reasons that I decided to purchase my Nexus 7 tablet -> model FLO.

Okay so i have a couple of questions...

First there seems to be some problems with people not being able to get Ubuntu Touch to load. They reported having issues with black screens; was this due to having an older version of MultiROM?

I installed MultiROM on my tablet through the MultiROM Manager app from the Google Play Store. Would you say that is okay, or should I go about installing multirom from the official xda thread?

Second:

What are the two files used for? Now i see that there is one zip file -> ubuntu-touch-4.4.2-system-armel+fl.zip and then there is a second. Now i am guessing that the touch-4.4.2-system-armel+fl.zip is the kernel since it was only 61MB's?

And i would guess that the second zip is the actual zip image for Ubuntu Touch...So for installation would we boot into Multi-ROM then go to add roms, add the ubuntu touch zip, then flash the kernel to the ubuntu touch zip?

If someone could elaborate a bit on the installation steps for getting ubuntu touch installed on the Nexus 7 FLO tablet i would really appreciate it!

Thank you all for your time and your assistance.

I hope to hear from someone soon, I can't wait to try this out!

ubuntu touch...stability issues?

Hello everyone, so for those of you who are actually using Ubuntu Touch I just wanted to know how you are doing with stability and what you think of the overall feel of the ROM.

Okay so one issue I seem to keep having is that every single time I start or restart Ubuntu Touch I am constantly having to enter my wifi key for my home Fios Internet system . Is anyone else having this issue?

Second apps seem to be running very slow and a lot of times i can't get them to even open up or have the apps perform like they should. For example I wanted to enter my login credentials for "Ubuntu One" but when i would click on the input box to enter my email address and password i couldn't get the virtual keyboard to come up...I ended up having to close the app several times and get the keyboard to show up.

Third...I can't seem to set my correct timezone or my correct time. Ubuntu Touch says that it is around 3AM but for me it is around 8:30PM. I am in the Southern California area, and I can't get the correct time to be displayed.

Fourth...I can't seem to get the terminal emulator to work correctly. Even when i try simple things like "which <command>" to verify that a certain command is installed, the Terminal just hangs and does nothing.

Last comment...has anyone seen an Ubuntu Store App? I don't know if I am just blind but I can't seem to find an Ubuntu Store app!? I would love to be able to add/purchase apps for Ubuntu Touch but I don't think I have this app on tablet?

Okay so here is just some of the small issues that I seem to be running into....I want you all to know that I am not complaining. I am VERY happy to have Ubuntu Touch on my Nexus 7 tablet but I just want to try and get the most out of it so I can customize it to my personal settings for a more enjoyable use. I know this project is in the development stage, so I am only posting this response to see if any other people here on XDA are having these same issues with Ubuntu Touch and maybe as a team we can all figure out a way to resolve these problems!

Thanks again everyone...and I hope to hear from someone soon!

[Nexus 7 (2013) General] Government:
almost there...

The last update to trusty touch is nearly there by my standards. I believe it is numbered 250 in multirom. I've left touch on for two days straight and having much less bugginess. Still not able to install synaptic and does not appear to have access to "Ubuntu" yet, or I guess canonical is more accurate. Updates are working very smooth now for me, wallpaper still kind of a bear to get changed and system customization is almost nonexistent. I'm hooked though, I'm looking forward to every update. Only thing I wish from this project is that they would go for more a Linux feel instead of droid feel, mini PC vs. Mobile device feel if ya follow me. But maybe with synaptic and some ui tweaks, one could get the custom feel.

Ubuntu Touch on Nexus 7 2013 only 2 Cores?

Hi,

I've recently installed ubuntu Touch on my Nexus 7 v2 (quadcore..) via Multiboot.

[Nexus 7 (2013) General] ImCoKeMaN:
Is there a way to ensure I have the latest version of Ubuntu Touch if I am installing via recovery? I may be a minority but I don't want to root my primary rom to use the Multirom App as then I can't use the tablet with my work email since they check for root. So far Multirom recovery and the custom kernel have been working fine, but I'd like to keep Ubuntu touch up to date.

I see the instructions from here:

https://github.com/Tasssadar/multirom/wiki/Using-MultiROM

This mentions a link to the cdimage files as zip files from http://cdimage.ubuntu.com/ubuntu-touch/daily-preinstalled/current/ , but when following the link they are .img and .tar.gz files.

Do these need repacked somehow?

Looking for some direction.

want to put Ubuntu on my N7 2013 using multi-ROM.

Questions are?

My kernel does not have the patch, what is compatible with Carbon Nighty 0609? That wont kill it.

Also currently running CWM recovery.

I knew I need to change it to Multi-Rom's TWRP.

will doing that wipe my device?

Or can I use Recovery Switcher to flash TWRP.

No access to a PC or Mac to use ADB or FastBoot to push anything.

Boot loader unlocked, rooted.

just looking for some ideas without killing my N7.

[Nexus 7 (2013) General] yofife2069:
Just download MultiRom Manager from the play store. You can do all you want to do from the app. It will not wipe your device. Pick the patched kernel that matches the version of android you are running. It will install their modded version of twrp. And you can also install Ubuntu from the app. May want to do a nandroid first.

[Nexus 7 (2013) General] Government:
wifi issue is a kernal mismatch

Same thing happened to me, two times actually. I, like a moron, decided to go the lazy route and upgrade my kernel via multirom that is in Android instead of recovery. It seemed logical right? There it was, available for download and install via multirom, why not.... well, at first it wouldn't boot at all. Meh... so I go to TWRP and get ready for a sideload.

All in short, Kernel and Rom have to match. I loaded a kernel for 4.4.3 and rom was still 4.4.2 and a custom this and custom that.

That is not to say that it WON'T work, but it caused my wifi to stop working or the tab to stop booting.

Easy fix for me was to start clean. I am always in a position to lose the data on the device, and of course it is safe somewhere else. So wipe/format back to factory. Then I went with CM11 4.4.3 with the matching Rom, from this site. 1st boot worked.

Went ahead and installed the KaliPwnPad as well.... timing was too perfect. Actually easier than I thought, minus the TLwifi adapter and Y cable I have to purchase.

Then went to install UTouch, and that went well. but I always have a question when I get to this point. Which version is everyone else installing?

Use the "official" method?

Been doing my homework in anticipation of my Nexus 7 arriving any minute.

I've installed the phablet tools into my Ubuntu desktop, but I don't think they're designed with Multirom in mind. If I follow the instructions to add the img files from the desktop terminal, eg

ubuntu-device-flash --channel=devel --bootstrap

(found on developer.ubuntu.com)

will that do? Or is another step necessary?
[Nexus 7 (2013) General] areshinakya:
You can use "multirom manager" on android to download and install Ubuntu touch as a secondary ROM.

You don't need your PC at all for that.

After that you can update Ubuntu touch from Ubuntu touch itself.

I bought my nexus 7 just for Ubuntu touch.

And i was completely shocked by its lack of quality and performance.

Biggest disappointment in 2014.

Problem is that Ubuntu touch users do not acknowledge performance problems. So it is unlikely they will get fixed.

On the other hand Ubuntu touch improved a lot in terms of stability and features in the last months.

Good luck with not hating it.
[Nexus 7 (2013) General] schermvlieger:
Needs more work

Ubuntu Touch installed and booted without problems following the instructions from the Ubuntu developer website.

It runs smooth enough, and the user interface of the desktop is something I could get used to over time.

However, neither the default apps that come with it, nor the apps that can be downloaded from the shop, can compete with what is available for Android. From gallery app to keyboard, each and every functionality present in the basic installation of Ubuntu Touch is one or two steps back from the default Android 5.x experience. One of the worst and most inexusable flaws is that many apps and system screens only work in portrait mode.

There'l be a long road ahead before Ubuntu Touch will be able to take away users from iOS and Android other than the most fanatical Ubuntu fans.

I've been using Ubuntu and - before that - other Linux distributions on my home computers since the mid nineties. Putting in some extra effort to make things work was always part of the deal on the pc platform, but with Ubuntu Touch as it is right now, it just does not seem to be worth the time and energy to go that route, yet.

I don't know that rom. But you are aware that you need a kexec capable kernel right? Does this rom have that? Did you install a kernel from within the multirom manager app? Maybe good to try to use some other android version as a secondary system in mrom and see whether you can boot that successfully.

Oh, there is rc-proposed for the nexus 7 now?! That's new right? I need to go find my Nexus 7 and try that.

If it is not kexec that is giving you a hard time then maybe it's just a bad UT version. I understand you already tried a couple, so it doesn't sound likely, but, maybe still: try an older stable?
