Users of rooted LG Nitro HD handsets who hope for a custom recovery on their device will finally get what they deserve. The guys at XDA-Developers have done it once again, and this time around their bringing ClockworkMod Recovery version (CWM 5) to the Nitro HD and the Optimus LTE.

LG’s recent contender in the smartphone race, the LG Nitro HD (and its international sibling, the LG Optimus LTE) surely has some awesome specifications to behold. On paper, the Nitro HD shines with its award-winning 4.5-inch AH-IPS LCD touchscreen and a whopping 1.5 GHz dual-core Scorpion processor. The device is spectacular to behold as it can play HD videos as smooth as butter without sacrificing certain functionalities.

Since its inception, rooting the Nitro HD has been tempting, as to do so can unlock an array of interesting features starting with the installation of custom ROMs. Even better, there might be a huge chance that you could install Ice Cream Sandwich on your device with custom CyanogenMod 9 ROMs.
