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 […]

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 […]

How to Root UG802 Rockchip RK3066 mini PC

If you follow this blog (and others), you should already know there’s a new dual core Cortex A9 Android mini PC in town based on Rockchip RK3066. Deadhp1, a reader of this blog, bought one and left a short review about the device, including his first impressions and an Antutu benchmark (6801). He also noticed that the device is not rooted by default, and followed the instructions for Window N90 II tablet (source: Slatedroid) to root the device: Download Moborobo Download a modified version of SuperOneClick – Short Fuse (Originally found in Slatedroid link above). Install Moborobo and start the program Make sure USB Debugging is enabled on your mini PC(Settings –> Developer Options) Connect your UG802 mini PC (using the microUSB port) to your PC Wait for Moborobo to detect the device Extract the contents of SuperOneClick Run SuperOneClick.exe Click on Root It will says the device is already […]

How to Allow Apps To Write Files to USB Mass Storage Devices in Android

When you’ve got an Android media player or mini PC, you may want to connect an external USB drive and allow write access to this drive to some applications. However, this is disabled by default in Android, although file managers appear to allow copy/paste of files to those drives without issue. Some applications may even refuse to install if they can’t find writable SD card or USB mass storage  device. I’ve tried to install the latest version of aTorrent (version 1.7.6) in my Mele A1000, and it could not install at all and returned a message like: Can’t install on SD card or USB device The solution below is adapted from a solution on XDA Developers Forums. Some instructions tells you to use an app such as Root Explorer to edit the files in Android (ES File Manager will also do, after allowing “Up to Root” option), but I personally […]

How to Create a Custom Android Firmware for CX-01 mini PC

I’ve written a post about updating the firmware on CX-01 mini PC last week. But, this week I’ve been able to go further since I’ve learned some tools available for Telechips TCC8902/TCC8903 firmware files are also compatible with TCC892X firmware files, and it’s possible to extract the firmware, modify/add files in different partitions and repack all this to burn it with FWDN tool. I’ll explain the different steps in this post, and even if you don’t own CX-01 it could be interesting as some of the commands are common to all Android devices. But first: BIG FAT WARNING!!! Although I believe the steps mentioned in this post are safe, and errors can be recovered by using the CX-01 firmware, CX-01 mini PC is not unbrickable, and if I’m wrong your device will become useless and you won’t be able to fix it. I may also mention some tools (but not show […]

How to Upgrade Firmware for CX-01 mini PC

[WARNING: Although these instructions worked with my hardware (CX-01 bought via Pandawill), it appears to break some CX-01 devices (See comments section), so use these instructions with care] Pandawill finally managed to release CX-01 firmware (234 MB) about a week ago. This firmware can be used for devices with 4 or 8 GB flash memory (2 separate directories). You only need to update the firmware if your device has some serious problems, or if CX-01 gets a proper firmware update (we can always dream…). Once you’ve downloaded ROM for android TV CX-01.rar in a Windows PC, extract it and enter ROM for android TV CX-01 directory. You’ll find 1 file and 1 directory: V1.0-4096-8189_en – Directory for 4GB firmware V1.0-8192-8189_en – Directory for 8GB firmware FWDN_8923.zip – Telechips tools to burn the firmware to flash Extract FWDN_8923.zip, go to vtcdrv directory and install the driver corresponding to your operating system.

How To Root CX-01 Android mini PC

CX-01 is a cool low cost Android mini PC (as low as $40), but unlike many other Chinese Android device it is not rooted.
