Last week, Geekbuying announced the first release of Android 4.2.2 for MK808, with support for MK808B coming soon. They warn users that it’s still beta since this is the first time Android 4.2 is available on Rockchip RK3066 mini PC, however I could not find user’s complains in the comments section, but at least one users in ARMTvTech is disappointed by this release. You’ll find three download links: Android 4.2.2 for MK808 (dropbox) – Currently unavailable due to heavy traffic Android 4.2.2 for MK808 rooted (Gdrive) – Same version as above but rooted by deadhp1 RKBatchTool  1.5 (dropbox)- Windows tool to perform the upgrade.

Latest Tronsmart Prometheus Firmware Features Android 4.2 and XBMC with Video Hardware Decoding

Last month I reviewed Tronsmart Prometheus, and I was pretty satisfied with the device except some bugs. There’s no a firmware update that should fix AC3/DTS static noise issues in this set-top box. Prometheus also becomes one of the first set-top boxes to support the latest Android Jelly Bean 4.2, and comes with an XBMC version supporting hardware decode using XBMC user interface, and not an external media player such as DicePlayer or MX Player. You can download the firmware ( 2013-3-08(4.2_root_ac3_dts_market_xbmc).zip), and install it using the upgrade procedure on Tronsmart website. I’m on the road, so I can’t try the firmware myself right now (which also explains why I haven’t posted in the last few days), but Geekuying has upload a short video showing XBMC with video hardware acceleration on the device. (Previous firmware in Android 4.1.2). Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and …

How to Display dd Progress and dd.sh Script

Upgrading software on Linux / Android boards or devices often involves copying images to an SD card or microSD. In Linux, you’d usually do that with dd, a utility that provides binary copy of data to files or block devices. A typical command would be: However, during the copy, dd does not show a progress bar by default. But dd actually supports progress report, as indicated in the manpage: you can run dd, and send USR1 signal to display the current progress once, and resume copying. Linux commando explains how to continuously return the progress. First run the dd command: Open another terminal window to find out the process id: And use the watch command to send USR1 at regular interval. You should see dd progress in the first window every 10 seconds. It works, but the output is not very nice because dd will just output 3 lines at a time, and you’ll see something like: I’ve recently come …

Droid Stick A2 Firmware With Google Play Fix

If you have read my previous review of the Droid Stick A2, I was pretty upset about Google Play since I could not install most of the apps. This is now fixed, and Kimdecent has released a firmware upgrade. Here’s how to upgrade: Download g02refDongle-ota-20130201.rar Extract it in your PC, and copy the files (g02refDongle-ota-20130201.zip and uImage_recovery) to the root of your microSD card (Formatted as FAT32) Insert the microSD into Droid Stick A2 Boot the mini PC normally, and launch the “Upgrade” app Select Local Upgrade, then select g02refDongle-ota-20130201.zip and click on Reboot and Install Package Droid Stick A2 will reboot, and it should start upgrading Android. Done Since I’ve been messing up with Android and broken something, “Reboot and Install Package” does nothing for me (some permissions issues with /cache/recovery/command), so I could not verify this works or not. Finally, I could install it on the first version of Droid Stick A2 and Google Play now works fine. …

Upgrading Embedded Linux Without Bricking – ELCE 2012

Arnout Vandecappelle, senior embedded software architect at Essensium/Mind, talks about ways to greatly decrease the risk of bricking your board/device during upgrade thanks to gubies scripts and tools at the Embedded Linux Conference in Barcelona, Spain, on November 6, 2012. Abtract: Embedded systems are often modified remotely, e.g. to upgrade the firmware or change the configuration. This may however break the system and render it inaccessible, which is a major problem if the device is hard to reach physically. Unfortunately, no catch-all failsafe solution exists to make sure that the device stays accessible remotely even if a modification goes wrong. Instead, the possible failures have to be anticipated and covered. This talk discusses some of the frequently occurring failures, how they can be detected and handled. These include power failure, kernel crashes, network failure and data corruption. We include examples of concrete use cases. Finally, there is room for discussion about possible alternative or more generic solutions than the ones proposed. …

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 …
