In the world of smartphones, some devices never cease to amaze us. And while it may not exactly be the HD2, the HTC Desire HD is certainly shows its lineage. HTC may have long declared end of upgrade support for this once flagship, the developer community hasn’t forgotten it at all, and it has been dual booted, made to natively run Ubuntu, given the latestHTC Senseports, and received working ICS and Jelly Bean 4.1 custom ROMs. The latest in this series of developments for the device is the AOSP-based codefireX Android 4.2.1 Jelly Bean ROM brought to us by XDA Senior Member synergye.
The ROM is completely open-source, and is built with an optimized Linaro toolchain for those who believe this helps performance. All features other than Bluetooth are working, and there are a lot of customization options to tweak it just the way you want. An additional kernel is also available from the same developer that brings several performance enhancements to the device on any Jelly Bean ROM.
