Android and openness is something we talk about all the time, but the recent developments in the industry point towards inherent flaws with this very premise. Be it from bloggers, political institutions or corporations, Android is seemingly not open enough. The “War on Openness” is ironically becoming an open war, where many players are increasing their stakes and scope to try and land a bigger hold - or at the very least, restrict Google’s - on what is the world’s...
HTC Topaz JTAG pinouts
Before today JTAG (Joint Test Action Group) pinouts for Topaz were completely unknown, but today the-equinoxe was able to discover them. This is a serial bus with four signals: Test Clock (TCK), Test Mode Select (TMS), Test Data Input (TDI), and Test Data Output (TDO). The bus is used as a test bus for the ‘Boundary-Scan’ of ICs, as in Design-For-Testability.

I purchased a drowned HTC Diamond 2 which I used to house my MDA V in.
Now I was in possession of a broken mainboard.
Since the JTAG pinouts are unknown till this date, I stripped the mainboard from all its components and traced the board in order to find the JTAG.
Had to make new probes from some needles in order to trace from the BGA-Grid..
The difficulty here was that the test-pins where on the other side as where the MPM 7200-A was, and with those tiny bga-vias it was real hard to trace.
Some pictures of the board (before stripping)
The front side of the Mainboard (it is a single board device, apart from speakers, LCD and antenna no further external parts, all on one board!).
The Pins I traced:
These should suffice to JTAG the device.

Smartphone cameras have advanced so tremendously over the past few years that they have almost completely replaced point and shoot digital cameras for the most of us. Furthermore, since our smartphones are always with us, the majority of us end up taking tons of photos throughout the lifespan of our devices. But what happens to all the old photos you take? Do you store them on an external hard-drive or keep them backed up to an online cloud service like Flickr? Let us know what your favorite way of storing old photos is and why.
Before the release of Android 5.0 Lollipop, the Holo Design guidelines served as the official reference for Android design, right from IceCream Sandwich to KitKat. However, updates to the guidelines were few and far between, leading to a lack of synchronization between Android design and current UI/UX trends. Google seems to have learned from their mistake the last time around, and earlier this week, a significant update was released for the Material Design guidelines, marking the second revision in less...
