Self Made UART JIG and Debugging Connector for SGS I9000

As of late, it seems that the engineers among us have begun surfacing as we are seeing an influx of threads regarding very specific topics, particularly in the I9000 section. XDA member UberPinguin shares with us the idea that he had while browsing through some of these threads. Most devices, ever since the Windows Mobile, era will come not only with bootloader and roms on them. There are various levels within the hardware hat can be accessed via specialty pieces of equupments, the likes of which you will likely not encounter in too many places outside of approved cell phone repair shops or electical engineers’ work benches. These extra modes in the hardware will allow you to communicate with parts of the hardware in the logic level and such a thing could have potential impact in things such as brick recovery. Uberpinguin, decided to make a multi purpose UART JIG device, which uses a switch rather than him manually changing resistors and cables around.

This is a very intreresting concept and the dev has been kind enough to show us the parts used as well as the schematic design of his creation. If you know what you are doing and would like to give this a go, please leave some feedback, particularly if you find something intereresting while messing with this.

After reading through some very interesting threads about the UART and JTAG interfaces on the Galaxy S phones, I decided to build my own JIG to trigger the various modes available.
However, I didn’t want to mess with splicing different resistors in, and I don’t like having lots of wires hanging about. So I decided to come up with a way to choose the mode by a switch, rather than switching out different cables or using breadboards.
The resulting design is:

Send Links to Any Nearby Device with CaastMe

There already are many solutions on the Google Play store if you want to send a link to one of your devices -- but what if you wanted to do it quickly without having to install any software or logging in to a website on the recipient end? Most apps require you to do either or both, which can be a hassle (or even a security risk) in some cases. Luckily, XDA Forum Member wyemun has developed CaastMe. Inspired by...

The Witcher Battle Arena: Hectic Multiplayer MOBA Fun

Do you like MOBAs? Do you like gaming on your phone? Given that MOBAs (multi player battle arenas) have amassed millions upon millions of players, there's a chance you play LoL or DOTA. And here at XDA we love phones, and we spend a lot of time on them, so if you were to like gaming outside of smartphones you probably like some on them too. I personally like neither, and I simply download the latest 3D games to see the progression...

LG G4 Could Feature a… 3K Display?

According to myLGphones, a version of the LG G4 will not feature neither a 2K nor a 4K display - but 3K. If you are anything like me, your reaction to this news will be confusion. While we don't have many details about the sources of this leak, it has apparently been confirmed true by a poster at hardare.fr that gave some more details on model names for each version of the upcoming LG flagship. However, these leaks don't point towards all G4...
