Last month, we have heard numerous Jelly Bean leaks for the Samsung Galaxy S3 and now it is HTC One X’s turn. A few members of the XDA have posted the leaked Jelly Bean ROM for some variants of HTC One X over on their forums. The international version of the HTC One X comes with a quad-core NVIDIA Tegra 3 processor. The leaked Jelly Bean ROM is based on the HTC One X+.
The ROM has Android 4.1.1 and HTC Sense 4+. To work, your ROM and your device must belong to one of the following CID groups. If your phone is not included, don’t install the ROM. The CID numbers that can install it include
