[DEV] Ubuntu Touch (Preview) for Huawei Mediapad

after_silence · Mar 1, 2013

This is a port of Ubuntu Touch (Preview) for Huawei Mediapad tablet (s7-30xx).

Keep in mind that:
- its experimental;
- not for daily use;
- only for developers;
- dont try install it if you have no skills at least in working with adb;
- you have to do a nandroid before installing;
- dont blame anyone for broken device

How to install (almost everything the same as for other cm9-10.1 releases):
1. Install twrp/cwm recovery.
2. Make factory reset.
3. Install the device specific part for Ubutnu.
4. Install the generic Ubuntu part.
5. Install dpi fix.
6. Reboot
7. Open terminal at PC, connect tablet via usb cable to it and enter the following commands:

Code:

adb root

Code:

adb shell

Code:

ubuntu_chroot shell

If you want to see GUI then type:

Code:

ubuntu-session

--- Enjoy the testing! --- (or not enjoy

)

Screenshots

Wow, this is great

too bad there is no networking, otherwise it is pretty neat

One bug is that the keyboard is too big for the screen (see messaging screenshot below).

Here are screenshots via ddms:

OMG!!! Thank you!!! Can we expect more of ubuntu touch for mediapad beyond a developer preview?

Sent from my Huawei MediaPad using xda app-developers app

That was a very quick try, so dont wait too much from it. Besides ubuntu touch in very very early stage of developing.
For keyboard Its needed to adjust ubuntu-session, i havent done it in proper way.

Rumbi · Mar 1, 2013

Please don't stop developing for the Mediapad.

By the way i have been able to setup wireless connection (to open access point, cant do it for wpa2)

To do it you need from

Code:

adb shell

perform the following:

Code:

insmod /system/lib/modules/dhd.ko firmware_path=/system/etc/wifi/rtecdc-bcm4329.bin nvram_path=/system/etc/wifi/nvram-bcm4329.txt

Then go to chroot shell via

Code:

ubuntu_chroot shell

and then setup wireless connection from there (in linux way from terminal

For example:

Code:

mount -t proc proc /proc
ifconfig wlan0 up
iwconfig wlan0 mode managed
iwconfig wlan0 essid your_ssid
dhclient wlan0

or something like that.

Hello, i have tried to get ubuntu touch running, but my screen stays black.
when typing ubuntu-session in adb I see two lines in response:
ubuntu-session
Redirecting output to local session logs

does not look that bad, but my screen stays black all the time
and i can not connect to the device via adb anymore.
any idea what is going on? I used the daily build from 8.03

thx and greetings

I tried to launch Ubuntu on my MediaPad
It's work onli in wire-to-pc mode. When I disconnect a Usb-wire - I have a blank screen.

Corn Flake · May 29, 2013

Any plans on future work on it?

I read that late may build should be for daily use so I finally managed to try it. I used latest raring build but I had no luck with getting GUI working :/

virtualXTC · Sep 1, 2013

Can I boot directly in, or is this Chroot only?

The install instructions include a chroot, but is that what ubuntu ends up running in? Is it possible to run without loading android into ram as well?

Thanks.
