Cydia Impactor Provides an Alternative Method to Root Android Devices via Windows or Mac OS X

August 24th, 2013 3 comments

Cydia Impactor is a GUI tool for working with Android devices from computers running Windows or Mac OS X.  It can be used to reboot the device, enter fastboot mode, access the shell, scan for USB drivers for your device, and a bit more.

Cydia_Impactor

But its key feature is to provide root access to many Android devices by exploiting of the Android “Master Key” vulnerability, and if it does not work falling back to a different signature verification bug. There are other tools (e.g. unlockroot, Moborobo,…) or methods to provide root access, but if those do not work or you have troubles installing drivers, Cydia Impactor may be worth a try.

I did try on MK908 and T428 mini PCs in a Windows XP netbook, but for some reasons the software could not detect the USB connection (with USB debug enabled in Android), although Moborobo did. But Benjamin, who tipped me about this application, told me he successfully rooted a Mediatek MTK6577 based phone, as well as a tablet powered by Rockchip RK3066.

If your device firmware has been patched against the two bugs used for the root exploit, you won’t be able to root the device. Currently three device/firmware combinations are known to not be rootable with Cydia Impactor:  Motorola Atrix 4D 4.1.1, Huawei Ascend Mate 4.1, and HTC One 4.2.2.

August 20th, 2013 5 comments

Ostec Electro-Optical Science and Technology, is a company headquartered in Shenzhen, China, with a factory based in Guangzhou, that manufactures optical devices such as telescopes, microphones, endoscopes, and scanners that connects to your computer, or tablet via USB or Wi-Fi. Charbax of armdevices.net interviewed the company in April at the Hong Kong Electronics Fair, and uploaded the video (see bottom of post) very recently. Let’s have a closer at some of the products.

KoPa WiFi Telescope (Model TW501)

The first device is TW501 Wi-Fi telescope that comes with a tablet holder, and allows you to visualize the picture directly on your smartphone, tablet, or other Wi-Fi capable device either via specific Apps or via the web browser.

KoPa W5 Wi-Fi Microscope and M101 USB Microscope

Ostec also manufacturer USB and Wi-Fi microscopes that act more like a powerful magnifying glass than an actual microscope as you may think of it. However, it’s still useful for the education market, beauty care, checking PCB traces, etc… The company lists 4 models in their site, including on that does look like an actual microscope, but during the interview, the focus was on W5 and M101 portable microscope, respectively with Wi-Fi and USB interfaces, both of which allowing for real-time visualization on iOs and Android devices, as well as Windows or Mac computers.

DroneShield – Raspberry Pi Powered Drone Detector

May 2nd, 2013 1 comment

In case you are wary of having drones, such as RC helicopters, quadrotors…, flying around your house and invading your privacy, DroneShield can help you detect consumers’ drones by using a Raspberry Pi, a microphone and FFTW library, a C library for computing the discrete Fourier transform.

DroneShield

The device will capture the audio with the microphone, analyze the noise spectrum of the drone flying around, and search for an entry in a signature database, and if a match is found the device will then send an email or SMS to inform you of the “invader”.
DroneShield_Block_Diagram

There are complex challenges to overcome, or limitations, with this method, as any background noise will affect the detection, and drone emitting little noise or flying at high altitude won’t be detected. Spectrum analyses should however help avoid false positives such as a loanmowers and leafblowers as those emit a different kind of noise.They also need to gather more signatures to store in their database for this device to be more useful, and plan to rely on the community, but I haven’t found links and/or instructions to do so yet.

Currently, they have a working prototype (DroneShield V0.0) on a laptop, and they’ll port the code to the Raspberry Pi (DroneShield V1.0). FFTW library supports x86 SSE/SSE2/Altivec SIMD instructions, as well as NEON instructions on ARM, which are not available on the ARMv6 processor (Broadcom BCM2835) used in the Raspberry Pi. I don’t know the processing power required to do real-time FFT, but there could potentially be performance issues on the Raspberry Pi.

They give hints, but do not commit, that they may release the source code for V0.0 and V1.0, as well as the hardware documentation for V1.0 after the indiegogo campaign.

You can get a DroneShield fully assembled by pledging $69 on Indiegogo, alternatively you can pledge $59 to get a box with all parts needed, and do the assembly yourself. Delivery is expected in August 2013. This is very much an “American thing”, and there does not seem to be an option to ship this internationally.

The next step, DroneShield V2.0, will be to build a specialized hardware, possibly based on ARM Cortex processor, and at a cost close to $20.

Collabora and Fluendo Release GStreamer SDK 2012.5 Amazon

June 14th, 2012 No comments

Last week, Collabora and Fluendo jointly announced the release of an open source software development kit (SDK ) for GStreamer multimedia framework.

The SDK aims at easing the integration of Gstreamer  into projects and provides a pre-built version of the framework which is available for Linux, Windows and Mac OS X.

GStreamer is used in many Linux applications such as media players (Rhythmbox, Banshee and Amarok),  video editors (PitiVi), and media centers such as XBMC among other applications. It’s also often the framework used to play videos on ARM platforms with implementations for OMAP 4/5 and devices compliant with the OpenMAX standard.

Gstreamer website has also been updated and provides links to download GStreamer SDK and documentation on the home page.

The new documentation looks pretty good with fives main sections:

GStreamer developers also announced that future releases of the SDK will support Android, iOS and possibly other platforms.
