Official Android 4.4 Firmware for RK3188T HDMI TV Sticks Released

At the very end of last year, a beta Android 4.4.2 firmware for Rockchip RK3188 mini PCs was released, and yesterday, GeekBuying announced an official Android 4.4.2 firmware for Rockchip RK3188T (notice the T) mini PCs with AP6210 Wi-Fi modules,with bug fixes from the beta version. This should work with device such as MK908II and MK809III. There are at least two caveats however. First, I understand it will only work on RK3188T, not RK3188, and hopefully an official RK3188 mini PC firmware will be released soon, but since manufacturers may have changed from RK3188 to RK3188T for the same model during manufacturing, you have to make sure which version you are using. You can do so by installing CheckRK3188 app on your device, and check if you have the slower RK3188T SoC, or the older, but faster RK3188. The second issue is that Google Apps (Play store, gmail) are not pre-installed. You […]

Android 4.4.2 KitKat Beta Released for Rockchip RK3188 mini PCs

I’ve just been informed that Android KitKat, version 4.4.2, is now available for Rockchip RK3188 powered mini PCs based on AP6210 Wi-Fi module. This is a beta version, but it’s known to work for MK908 II, CX-919, GM282, GK525, iMito QX2, and IPPLI Mars I2C HDMI TV dongles. Albeit MK908 is also based on AP6210 Wi-Fi module, it does not appear to work right now, and the “new” model of MK802 IV with AP6210 might work, but has not been tested. Devices based on AP6330 and other Wi-Fi modules, such as T428 mini PC, are not working with this firmware, and you’ll have to wait a few more days or weeks to get a compatible firmware. Android 4.4 will bring new features that can be interesting with mini PCs such as printing support, screen recording, and overall better graphics and streaming performance. So with the recent release of AndrOpen Office,  […]

How-to Install and “Hack” Linux on T428 or MK802 IV mini PCs

PicUntu 4.5 installer is probably the easiest method to install Ubuntu on a Rockchip RK3188 based mini PC, but if you want a little more flexibility I’ll provide another method to install Linux on T428, MK802 IV or compatible devices, as well as links to go further: dual boot Android / Linux, create your own official distro, status of Mali-400 GPU support in RK3188… The method below is not new, as it was posted by Linuxium (Ian Morrison) in Freaktab in September, but this is the first time I’ve taken the time and managed to run Linux on Rockchip RK3188, and I’ll provide some more detailed steps. Prerequisites Even though in some cases it’s possible to install Rockchip firmware from Linux, AFAIK the tools available in Linux lack supports for the parameter and loader files, so ironically, you’ll need a Windows XP/7/8 machine to install Linux in your mini PC.

How to Flash Rockchip RK3066 / RK3188 Firmware in Linux

Rockchip provides 2 tools to update the flash: RkBatchTool – Used to upgrade firmware with a single file RkAndroidTool – Used to flash the NAND flash with image corresponding to particular partition, e.g. system.img. kernel.img, boot.img. recovery.img. etc… One problem is that the company only provides these tools for Windows, so if you’re using a Linux based operating systems, you’d have to run a Windows XP or 7 virtual machine in VirtualBox or VMWare, which is an inconvenience, and requires a license in theory. To work around this issue, I’ve tried to use ReactOS, an open source operating systems compatible with Windows XP, but although the USB drivers appeared to install properly, RKAndroidTool failed to recognized my device (MK908). But a member of Mini PCs community informed me about a tool called RkFlashKit, written in Python and using GTK, that can flash firmware to Rockchip RK3066 and RK3188 devices in […]

Binwalk Utility Helps You Analyze and Reverse-Engineer Firmware Files

Binwalk is a “firmware analysis tool designed for analyzing, reverse engineering and extracting data contained in firmware images”.  This tool written in python supports Linux, and somewhat Mac OS X, can scan firmware files for files signature, and can be useful for hacking firmware files, and finding hidden information. Let’s install binwalk first. It’s very easy in a Debian or Ubuntu machine, as you just have to download the package, and run a script for installation:

If you have another Linux ditributions, it’s just a little more complicated. You still need to download and extract the release package as above, but you’ll have to install the following package depending on the features your need: Minimal installation – python 2.6 or greater, and  python-magic To generate entropy plot graphs – python-matplotlib For automated extraction: Packages – mtd-utils zlib1g-dev liblzma-dev gzip bzip2 tar unrar arj p7zip p7zip-full openjdk-6-jdk Build and install […]

Firmware Update for CS868 mini PC Version 2.06 (Android 4.1.1)

If you’ve got a Rockchip RK3188 mini PC, there’s usually no issue with finding firmware updates, or even custom ROMs. But if you’ve bought an AllWinner A31 mini PC, such as CS868, you may feel everybody dropped the ball, as the system is not stable, and it seemed there would never be any upgrade. I’ve recently been made aware that there’s some activity on a Chinese bulletin board, and a new firmware is available for CS868: V2.06-4.1.1-20130610. As the name implied, the firmware is based on Android 4.1.1, and has been release on the 10th of June 2013. Here’s the Changelog against V2.05: Add video color brightness, contrast and saturation settings Output to HDMI output by default Other systems optimization and the Changelog against V2.04 (22nd of May): Reduce DDR frequency to improve system stability. Fixed potential sound failure. Optimize USB OTG interface to fix issues with Air mice. Increase […]

I’ve just received a mini PC powered by AllWinner A31, and I had to (re-)install the firmware, so I’ll explain the steps I followed in this post. The procedure is for CS868 mini PC, but it should be similar for all Android HDMI TV dongles, and media players based on AllWinner A20 or A31.The procedure below only works in Windows, and has been tested in Windows XP. I’ll mention a possible method in Linux at the end of the post. Download the latest CS868 firmware and tools, and extract “cs868 firmware and update tool 20130507.rar” file Download PhoenixUSBPro tool in English, and extract This is optional as the Chinese version is included in rar file above.
