Installing Ubuntu Phone (Touch) on Nexus 7 LTE

ubuntu phone

Add SDK repository

sudo add-apt-repository ppa:ubuntu-sdk-team/ppa
sudo apt-get update
sudo apt-get install ubuntu-device-flash

Enable USB Debugging on the device

  1. Make sure you have developer mode enabled (see http://developer.android.com/tools/device.html if you are unsure).
  2. Navigate to Settings > Developer options
  3. Enable USB Debugging. When a device is connected, you will be prompted in Android to authorize it.

Unlock Bootloader

adb reboot bootloader
fastboot oem unlock
fastboot reboot

Check that you have the right device

adb shell grep ro.product.name /system/build.prop > mydevicedata \
&& adb shell grep ro.product.device /system/build.prop >> mydevicedata \
&& adb shell grep build.id /system/build.prop >> mydevicedata

ro.product.name=razorg
ro.product.device=deb
ro.build.id=KTU84P

Check which channels are available

ubuntu-device-flash --server="http://system-image.tasemnice.eu" query --list-channels --device=deb

ubuntu-device-flash –server=”http://system-image.tasemnice.eu” query –list-channels –device=deb
ubuntu-touch/ubuntu-rtm/14.09
ubuntu-touch/ubuntu-rtm/14.09-proposed
ubuntu-touch/utopic
ubuntu-touch/utopic-proposed
ubuntu-touch/vivid
ubuntu-touch/vivid-proposed
ubuntu-touch/devel (alias to ubuntu-touch/vivid)
ubuntu-touch/devel-proposed (alias to ubuntu-touch/vivid-proposed)
ubuntu-touch/ubuntu-rtm/devel (alias to ubuntu-touch/ubuntu-rtm/14.09)
ubuntu-touch/ubuntu-rtm/devel-proposed (alias to ubuntu-touch/ubuntu-rtm/14.09-proposed)

In my case I am going for the currently stable ‘ubuntu-touch/vivid’ channel.

Install Ubuntu Touch

ubuntu-device-flash --server="http://system-image.tasemnice.eu" touch --channel="ubuntu-touch/vivid" --bootstrap

CyanogenMod 12 on Sony Xperia Z2

Just a quick update of the previous article on “Sony Xperia Z2 upgrading to CyanogenMod 11“.

One thing is that CM now included the custom recovery and you do not need to download any other custom recoveries !

Download the CM 12 ZIP file for Sony Xperia Z2 (sirius) and extract the ‘boot.img’ file

Download link: https://download.cyanogenmod.org/?device=sirius

Get the device into fastboot (bootloader mode)

fastboot -i 0xfce flash boot boot.img
fastboot reboot

Install CyanogenMod

Choose the “Install zip from sdcard –> Install from sideload” option

adb sideload cm-12-20150219-NIGHTLY-sirius.zip

After the install has finished choose the “Reboot system now” option.

Vodafone LTE mobile data on Cyanogen Mod

I have had some issues recently with getting LTE (4G) connectivity on the Vodafone Australia Network using CyanogenMod 11 on multiple devices (http://forum.cyanogenmod.org/topic/92919-no-4g-signal-on-vodafone-au/). Turns out that it was an APN issue after all.

The APN provisioned by default when the Voda SIM card is inserted (vfinternet.au) does not work for the LTE Data Network. It works with GPRS & WCDMA, but fails to connect when the phone is set to prefer LTE (4G) Networks and they are actually available. It means that the handset will loose mobile data connectivity altogether. There are various APN Settings floating around on the interwebs, but any I tried previously did not fix the issue.

Ater needing to call Vodafone support for another device (on GPE Stock Android) that was experiencing the same issue I got given these APN Settings:

Settings –> Mobile Networks –> Access Point Names

APN Name: Vodafone AU
APN URI: live.vodafone.com

Leave all other settings at default (for MMS settings see the link to VF Support below).

I have tested this for 2 days and works beautifully. The correct APN settings can be found here: http://support.vodafone.com.au/articles/FAQ/APN-Settings

Sony Xperia Z2 upgrading to CyanogenMod 11

Contrary to my normal inclinations not to buy anything but Stock Android phones I ended up with a Sony Xperia Z2 in a hurry over the weekend (it’s a long story…). It appears to be quite a decent handset (with a pretty good camera actually) and one of the main reason to choose this over the other options was that is was one of the few high-end devices which already had a CM snapshot rather than just nightly releases. However similar to their colleagues at Samsung the Sony people also opted to stuff all sorts of crap-ware bloat onto the Android base OS. It appears not to be as bad as the Samsung (who are the kings of crap) mods, but for somebody used to the clean Android experience it’s just very annoying. So I opted to flash it straight to CyanogenMod.

Prerequisites

You need the Android SDK installed and on your Path – see one of my other posts on how to do this.

Get Bootloader Unlock Code

Another annoying step which is not required with Google Nexus series.

http://unlockbootloader.sonyericsson.com/instructions

You will need to enter and confirm your email (WTF?) and need your IMEI number and at the end of the process you will get an update key that is required below.

Put phone into bootloader (fastboot) mode

Insert one end of the USB cable into your PC. Turn off the device and wait at least 5 seconds. Press and hold the Volume Down button and plug the other end of the Micro-USB cable in to your device.

fastboot devices
#should display the ID of the connected phone
fastboot -i 0x0fce oem unlock 0xKEY

Download CyanogenMod Release

Extract the boot.img file from the downloaded ZIP file via https://download.cyanogenmod.org/?device=sirius

fastboot -i 0xfce flash boot boot.img
fastboot -i 0xfce reboot

This should boot into Clockwork Mod Recovery and you can use the Volume +/- to navigate and On/Off button to choose.

Select the “Wipe data/factory reset” option

Note: this part was not in the CM Wiki or anywhere else and took me a while to get past. If you see an error “Error Mounting /sdcard/.android_Secure!” during the factory reset procedure you need to format the data partition manually. If you do not do this step the CM install will still work but you will not be able to boot the phone (it gets stuck at the Boot Animation).

Mount /data
Format /data

After the manual format procedure do the “Factory reset” again.

Install CyanogenMod

Choose the “Install zip from sdcard –> Install from sideload” option

adb sideload cm-11-20140804-SNAPSHOT-M9-sirius.zip

After the install has finished choose the “Reboot system now” option.

Finding a private location check-in service

Foursquare decided that it was too hard for them to compete with location services like Yelp and split their app into two separate apps. Whilst that might make sense to the 4Square CEO and his VC masters, it makes no sense from a users perspective. Foursquare can be a bit of a battery hog already, and having 2 apps to open and “annoy” you with notifications is not an improvement by any means. And if I wanted Foursquare to be Yelp – I would have used Yelp in the first place. So no – I do not want to install another separate check-in App (called Swarm). One battery hogging location app was enough.

no checkins here by leogaggl, on Flickr

The other argument used by 4Square’s CEO is that he didn’t want users confused about the “gamification” aspects of 4Square. I personally think that this is highly patronising to the Foursquare user base. I am sure most users would be able to work out what it is useful for.

Since I have always used 4Square mainly as a means to get some analytics of my movements and historic record of where I was at what time (I always downloaded my checkins to Thinkup on my own server) I was trying to find something that would fit the same use case. Meet Ushahidi (http://www.ushahidi.com/) – an excellent geo-coded “reporting” service developed in Kenya. I have been following this project for years already.

Dynamic Timeline

Track your reports on the map and over time, filter your data by time, and see when things happened and where.

Interactive Mapping

One of the most powerful ways to visualize information is to display it on a map. The Ushahidi platform give you rich information mapping tools.

Multiple Data Streams

The Ushahidi Platform allows you to easily collect information via text messages, email, twitter and web-forms.

Free & Open Source

The Ushahidi Platform is free for you to download and use. It is released under the GNU Lesser General Public License (LGPL).

Installation information for your own Ushahidi Server can be found on GitHub – or you can use their hosted service called Crowdmap.

Whilst this is obviously not an option for everybody it works for me. I will miss some the social aspect of 4Square as I had a small number of people I was sharing my check-ins with and it did bring about some by-chance meetups & conversation about other people’s check-ins. But the Ushahidi instance can be shared between multiple people. Maybe some will come along for the ride.

So long Foursquare – it was nice while it lasted ! If you treat your users like sheep – all you will be left with is sheep…

Upgrading Nokia X to CyanogenMod 11 (via Ubuntu)

The Nokia X seems to be a nice piece of hardware for just around $125 AUD. Nothing spectacular in terms of computing power, but much better build quality than your average cheap Chinese Android clone. I have always been a fan of Nokia hardware until they decided to commit suicide by firstly adding CEO Stephen Elop and ditching all of their software for Windows Mobile.

The problem with the device out of the box is that is has a horribly butchered version of Android. And by horribly I mean way worse than the usual bloat and crapware that poor Samsung, HTC or Sony users are normally subjected to. Hopefully this is only Nokia’s first step to a more open platform, but I wouldn’t hold my breath on that one.

Before committing to buy this device I made sure that I could flash it to CyanogenMod as soon as it arrives. Sidenote: I purchased from Mobicity AU – which turned out to be a big mistake. Do yourself a favour and go somewhere else unless you have weeks to wait.

Nokia X - CyanogenMod 11

Boot Mode – Nokia X

Nokia Recovery Mode:

1. Turn off your device
2. Press Volume + and Power Button 15 seconds

Dependencies

If you haven’t got the Android SDK or tools yet you need to install

sudo apt-get install android-tools-adb android-tools-fastboot

USB Configuration

sudo vim /etc/udev/rules.d/51-android.rules
#add the following line
SUBSYSTEMS=="usb", ATTR{idVendor}=="0421", MODE="0666", OWNER="plugdev"
sudo service udev restart

vim ~/.android/adb_usb.ini
#add at the end of the file
0x0421

sudo adb kill-server
sudo adb devices

Rooting the device

Download ClockWorkMod Recovery (or TWRP if you prefer).

http://forum.xda-developers.com/showthread.php?t=2703708

Check USB debugging in “Settings –> Developer Options” (it seems that the NokiaX has debugging enabled out of the box)

Boot into Recovery (see above)

sudo adb reboot bootloader
sudo fastboot -i 0×0421 flash recovery cwm-6028-normandy.img
sudo fastboot reboot

Installing CyanogenMod 11

Please note that currently this is not an official CM release but an unofficial port, however CM has already committed to taking this device onboard as an officially supported one in the near future.

EDIT 2014-06-17: WIFI is currently not working which should be a showstopper for day-to-day use.

Boot into Recovery (see above) – this should now be CWM Recovery rather than the previous Android Recovery.

Download files:
CM 11 ROM for Nokia X (Android 4.4.2)
Google Apps for CM 11

EDIT (2014-09-29): There seems to be a more complete version of CM11 here: http://forum.xda-developers.com/nokia-x/development/rom-cyanogenmod-11-m8-4-4-4-t2838336

In CWM recovery, select “Data Wipeout / Factory reset” option and wipe the data.
Select “Wipe Dalvik cache” from the Advanced Option
Select “Install ZIP –> Install ZIP from sideload”

sudo adb sideload cm-11-20140426-UNOFFICIAL-normandy.zip

Select “Reboot system now”

Note: the reboot can take about 1 minute to get started due to a bug in the current CWM Recovery.

Enjoy !

EDIT 2014-07-22: Since there doesn’t seem to be any active development on the CM port for Nokia X (which seems a shame since they are so cheap) I found an AOSP ROM (based on Android 4.1.2) which seems to be workable as a day-to-day phone.

Upgrade Rikomagic MK902 Android MiniPC from Ubuntu

If there would be an Oscar for the WORST firmware upgrade procedure (and associated drivers, documentation and general quality of software) Rikomagic should win this by a country mile !

Rikomagic MK902

Since all the information I found on the interwebs said Linux was not supported I ended up borrowing friends notebooks (as I don’t own any Windows machinery anymore). My main Toshiba Ultrabook seemed to have issues with picking up the USB from a Windows Virtual Machine). After not being able to get the absolute crap USB drivers that come with the firmware download with any of the machines (Vista & Win7_64) I was ready to throw in the towel and put the purchase of this unit (in hindsight I would not do it again anyway) down as a total waste.

I tried a last search on upgrading using Linux it turns out there was a very recent Rockchip Linux Upgrade Tool release.

Download Upgrade Tool

http://dl.radxa.com/rock/tools/linux/Linux_Upgrade_Tool_v1.16.zip

Dependencies

If you haven’t got the Android SDK or tools yet you need to install

sudo apt-get install android-tools-adb android-tools-fastboot

USB Configuration

sudo vim /etc/udev/rules.d/51-android.rules
#add the following line
SUBSYSTEMS=="usb", ATTRS{idVendor}=="2207", MODE="0666", GROUP="plugdev"

Restart udev
sudo udevadm control --reload-rules

vim ~/.android/adb_usb.ini
#add at the end of the file
0x2207

Restart the adb server

adb kill-server
adb start-server

You should be able to test with
adb devices

The output should be like the following:

adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
0123456789ABCDEF recovery

Please note: for adb to recognise the device it needs to be booted in recovery mode (as per the instructions in the so-called “documentation” from Rikomagic).

Boot into recovery mode

  1. Plug in USB Male-to-Male connector into the port marked “Slave” – not the other 3 hubs
  2. Press the “Reset” button using a paper-clip or similar pointy object (I used a letter opener which at times I would have loved to use on whoever came up with the crap Windows-only drivers and wasted hours of my life I will not get back… :P )
  3. After 3-5 seconds release reset button and plug the other end of the USB Male-to-Male connector into the Ubuntu box.

Upgrading

This bit took me a little while to work out. Turns out the device was in recovery mode and for the firmware upgrade process needs to be in bootloader mode.

Boot Device in Recovery Mode

Set the device into bootloader mode with adb.

adb reboot bootloader

Testing the bootloader mode

sudo ./upgrade_tool

./upgrade_tool List of rockusb connected
DevNo=1 Vid=0x2207,Pid=0x310b,LocationID=10c Loader
Found 1 rockusb,Select input DevNo,Rescan press ,Quit press :

Run the final upgrade of the downloaded image.

sudo ./upgrade_tool uf RKM_MK902_4.4.2_20140515.img

Android SDK issues on Ubuntu 14.04 64bit

Since the upgrade to Ubuntu 14.04 (Trusty Tahr) I have had issues running the Android SDK Tools. For example this error:

./adb
bash: ./adb: No such file or directory

Check the multi-arch architectures installed on the system.

sudo dpkg --print-architecture

Mine only showed ‘amd64’. Turns out you need to add the i386 architecture and install libc6:i386,libncurses5:i386,libstdc++6:i386 library packages.

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
sudo ./adb

Synology OpenVPN connection from Android

Connecting securely to your home network has always been a bit of a challenge since common home ADSL routers not normally contain any VPN Servers (those which do contain such are generally PPTP servers which I would hardly call secure these days). Which is probably a good thing as they would be horribly out of date considering the firmware release policies of retail router manufacturers. You could run/maintain your own dedicated server, but for most home networks that is overkill and out of the technical depth of most hobbyists. However NAS Appliances are becoming more useful in home networks for storage and other common tasks. I have had good experiences with Synology NAS devices over a number of years and the latest iteration also has a very useful VPN Server package available based on OpenVPN (as most Synology Apps are common Open Source components).

Server Requirements

This is a very straight forward procedure via the Synology Web UI (http://www.synology.com/en-uk/support/tutorials/459#t3.2)

Synology Openvpn

  1. Installing the VPN Server via Synology Package Manager
  2. Enabling OpenVPN Server
  3. Export the certificate using the button “Export configuration” (openvpn.zip) and extract the CA Certificate file (ca.crt)
  4. Forward UDP Port 1194 from your modem/router to the Synology NAS
  5. Make sure your Diskstation user account has OpenVPN privileges

Android Client Configuration

This part turned out a little more difficult than I expected. Initially I tried the “OpenVPN Connect” app by OpenVPN.net the makers of OpenVPN. However this seems to have no facility to edit the configuration and would not work at all from the imported config file.

The OpenVPN client that works well for me is OpenVPN for Android (https://play.google.com/store/apps/details?id=de.blinkt.openvpn)

  1. Transfer the CA Certificate (ca.crt) extracted in the previous step to the sdcard of your Android device
  2. Install the “OpenVPN for Android” app from the Google Play Store
  3. Open the “OpenVPN for Android” app, touch the + icon in the bottom left corner of the screen to add a profile
  4. Touch “Basic”
    1. Enter profile name and server address (Static IP Address or DynamicDNS of your modem/router)
    2. Touch the Select button for the CA Certificate
    3. Navigate to the file ca.crt on your sdcard and select the file
    4. Fill in the username and password of the Diskstation user with OpenVPN privileges
    5. Touch the back softkey or button of your phone
  5. Touch “IP and DNS”
    1. Check Override DNS settings by Server (Synology’s OpenVPN implementation currently does not support pushing servers)
    2. Google’s public DNS servers are the default and should work for most users)
    3. Touch the back softkey or button of your phone
  6. Touch “Authentication/Encryption”
    1. Uncheck Expect TLS server certificate
    2. Touch the back softkey or button of your phone twice to return to the app’s Profiles overview page
  7. Touch your profile’s name to connect (the icon with the sliders on the right allows to edit the profile)

Voila! Your Android device should now securely connect to your home network!

Connection Android 4.x MTP mass storage to Ubuntu 12.x

The ability to connect Android 4.+ devices to Ubuntu using the USB Mass Storage interface has always been a pain. With Ubuntu 13.04 a new MTP back-end (gvfs-mtp) is going to be introduced, but I have had some issues with the 13.04 Beta so I found this backport PPA to Ubuntu 12.04 and 12.10

sudo add-apt-repository ppa:langdalepl/gvfs-mtp
sudo apt-get update
sudo apt-get install gvfs
sudo apt-get upgrade

Kudos to Phillip Langdale for the work and maintaining the PPA !
