The wait is finally over for owners of the HTC One X as Cyanogenmod 9 aka CM9 has been unleashed for it by the TripNDroid Mobile Engineering team of developers at the Modaco Android forums. CM9, with its improved performance and stock AOSP look is the custom ROM that everyone awaits for a new device, specially a flagship device such as the HTC One X.

However, the ROM is in its early stages of development, so there a few issues in it, which are listed in the Known Issues section under ROM Info below. Unexpected bugs may show up at any time, but that’s to be expected as long as the ROM stays under development.

The methods and procedures discussed here are considered risky and you should not attempt anything if you don’t know completely what it is. If any damage occurs to your device, we won’t be held liable.
