There is a thread going around I'm the Ubuntu forums telling you to edit your buildprop to nexus 5 and a few other things and then the downloader works. Not sure if it works for everyone but,has anyone given it a try?

Wasn't the main reason this project died because the TF101 does not have NEON support or something like that?

Hardware limitation, nothing a build.prop edit could fix I think

I mean, my understanding of this is it just tricks the downloader to believing you're a N5. Then it will install Ubuntu.

To my limited knowledge you're right however, this is just to use the Ubuntu installer. I would like to try and get Ubuntu at least on and playing with it lol. I'm fairly new to the TF forums.

Also, while I'm here, if this is a Tegra issue, why does the Nexus 7 not have this issue?

can anyone tell me why https://goo.im/devs/jholtom/ubuntu-touch-tf101.zip/ is not working as a download?
i gave my best, but there is no way to click anywhere on that page, it also says nothing about downloads. ofc there is the usual paypal button asking to sponsor a thing which ofc i wont do because i want a download not spending my money.

ideas? mirrors?

Yes and downloading things made for the Nexus 5 is not a good idea.

Because it's been removed from the server, we were discussing it a few posts back

    Hello All, I've got Ubuntu Touch compiled for our beloved TF101's.

    Thread by TomTcom with instructions on how to build: http://xdaforums.com/showthread.php?t=2326453 <- Same way I do it, so have at ye!

    Remember this is still in Alpha on the ubuntu end, and our end too, but is still getting better, well at least ours is.

    New pretty picture attached by Oeio

    Instructions
    - First download the latest image (below).
    - Then download quantal-preinstalled-phablet-armhf.zip from here
    - Place both of these files in a place where you can flash them from recovery
    - Wipe data
    - Then flash the ubuntu-touch-tf101.zip, and then quantal-preinstalled-phablet-armhf.zip. IN THAT ORDER
    - Reboot and you should be good to go, make sure to clear cache.....
    - After reboot follow the instructions in post 3 to fix the resolution, and then reboot again.

    Thanks *Detection* for the screenshots and video (and onkelbebu)

    Information:
    - The Ubuntu Touch system is currently in developer-preview state, just to give you an idea of how incomplete this is.
    - My build sources may be broken; either get along with it or wait for me to fix it.
    - No longer am I the sole developer, we now have onkelbebu on board pushing changes and updating.

    SOURCES
    My modified device tree is here:
    https://github.com/jholtom/android_device_asus_tf101
    Now using this kernel
    https://github.com/jholtom/kernel_asus_tf101-lumpy

    Sources for Ubuntu are at:
    http://phablet.ubuntu.com/gitweb


    Thanks:
    onkelbebu, for his help with getting wifi working, and everything else.
    RaymanFX, Timduru and others for the kernel and device tree.
    *Detection* for being an awesome first tester.
    and of course, Canonical :p

    Don't forget the Thanks button :)

    That script is just what i'm adding into the flash of 0.5 so that no one has to do the screen resolution fix themselves, on first boot it will run and patch if for you.
    Expect 0.5 within 2 hours of this post.

    DEPRECATED - no longer needed as it now autofixes on first boot
    Fix for the Screen Density - Copy and Pasted from the Ubuntu Wiki.

    Instructions (Run from shell with transfomer connected and on.)
    adb shell
    ubuntu_chroot shell
    vi /usr/bin/ubuntu-session

    Find and edit the values for the following entries (there are two entries for each:
    GRID_UNIT_PX=10 (as suggested - read below)
    QTWEBKIT_DPR=1.2 (looks best to me by trial and error)



    SCREEN PIXEL RATIO

    We have 2 important variables that define the pixel ratio behaviour of the system and the applications, ie. how they visually scale. Look at /usr/bin/ubuntu-session for GRID_UNIT_PX and QTWEBKIT_DPR. Add another device specific settings there based on your device, using the method below to calculate the desired DPR.

    The number of pixels per grid unit (GRID_UNIT_PX) is specific to each device. Its goal is to make the user interface of the system and the applications of the same perceived size regardless of the device they are displayed on. It is primarily dependent on the pixel density of the device’s screen and the distance to the screen the user is at. That second value cannot be automatically detected and is based on heuristics. We assume that tablets and laptops are the same distance and that they are held at 1.235 times the distance phones tend to be held at.

    A reference device has been chosen from which we derive the pixels per grid unit for all other devices. The reference device is a laptop with a 120 ppi screen and the pixels per grid unit is set to 8 px/gu.

    Asus Transformer Tablet - 1280x800 - 149 ppi - 10 px/gu

    There is no way for the system to dynamically identify the correct pixel ratio for the device, which as a side effect things might be bigger/smaller than expected. For each device you will have to visually verify the quality of the result and adjust the number if necessary. If unsure, send screenshots and screen specifications of the device to the Canonical design team.

    New information for porters

    Friends,

    Daniel Holback send some new information for help the porters. The ports sources will be available through the https://code.launchpad.net/~tf101-image-dev and merge requests will be welcome. :good:

    I will make some fixes to revamp the tf101 port availability and tomorrow I will send more information about how to fork this. My build will be saucy based, fliped image. Links in some hours with the steps to help with the upstream project. :fingers-crossed:

    Thanks to jholtom and everyone else helping in this :highfive:
