Running Ubuntu in Android with ODROID-X Development Board

I’ve had several people asking me about running Linux on Android in the last few months, but I did not look into it into details, because I thought we would just be able to run server apps. That is until Rohith left a comment on CNX Software Facebook timeline,  that it’s possible to run Linux in Android, and access the user interface via VNC (sort of simple, but I did not think of it). You probably need at least 1GB of memory and a multi-core processor to run this sort of setup correctly, so I finally decided to give it a try by running Ubuntu 12.04 with Unity interface in ODROID-X development board. I mainly followed the instructions available at http://linuxonandroid.org/ and inside the Android app. Most of the steps I followed can also be replicated on other rooted Android hardware platforms. Apart from Ubuntu 10.04 & 12.04, you can also install Debian and Backtrack distributions. Updating Android, rooting and …

How to Root Kimdecent T21 mini PC and other Nufront NS115 Android Devices

The guys at androidpc.es have acquired a Kimdecent T21 mini PC (aka GV-21) based on the dual core Nufront NS115 processor, and posted instructions to root Kimdecent T21 in Spanish (and now in English) before writing a full review which should be posted next week. Here are the English instructions below: Download Moborobo and install it. Moborobo need to install unsigned drivers. By default, Windows 8 is not too happy with unsigned drivers, and you’ll have to follow these instructions, if you use that OS. Download ROOT-T21 and uncompress it. Make sure USB Debugging is enabled in your mini PC (Settings –> Developer Options) Install Moborobo Daemon from Google Play. Start Moborobo in the PC Execute  ROOT_T21_GV-21_V01.bat inside ROOT-21  folder and follow the  instructions. Moborobo needs to reconnect with T21 via Wi-Fi when the ROOT programs requires it. Once the procedure is complete, you can download and install SuperSU, as well as the latest version of Busybox. Those instructions may also work for …

WM8850-MID Tablet Firmware Files and Root Instructions

I’ve bought a noname tablet described as W8850-MID in the Android Settings that did not come rooted, and after several attempts trying to find how to root the tablet I had more or less given up, as tools such as UnlockRoot or OneClickRoot did not work with the device. After not using my tablet for 2 months, I started it again, but it just showed the Android animation forever, and failed to boot to the home screen. So I had to do something and finally managed to find firmware files for the device and root it. I’ll explain the whole process I went through in this post, but basically all you have to know is that if you have the same WM8850-MID tablet as I have (WM8850_MID7_PuZhi_W01_8223), it is fully compatible with Eken W70 and you can just install the latest W70 firmware (v1.10) from Eken support site that comes already rooted or use a tool called RootBurner (if you …

Building Kernel Modules for AllWinner A10 Android Devices (e.g. Joystick Support)

Reader JP has enabled Joystick support in Android 4.0.4 on its Mele A1000, this now works with a Playstation2 joystick via USB adapter, a Huskee PC joystick, and 2 other unbranded joysticks. In order to enable Joystick support he had to build a kernel module, and encountered a few issues, so he wrote an how-to which shows what challenges he went through and what solutions he found to those issues.I’m sharing today a slightly edited version of this how-to. This How-to assumes that you have a valid Linux environment where you can build allwinner A10 kernel. The toolchain used was “Sourcery CodeBench for ARM GNU/Linux Lite“ which can be downloaded here: http://www.codesourcery.com/sgpp/lite/arm/portal/package7853/public/arm-none-linux-gnueabi/arm-2010.09-50-arm-none-linux-gnueabi.bin To install it, simply run: You’ll also need the latest Allwinner A10 kernel source: Then follow the usual procedure: I then selected the modules needed for different kind of joysticks namely: I saved the settings and continued the build: Then I copied my modules to my sdcard, went …
