How To Install CyanogenMod 9 / MIUI 4 On HTC One X [Tutorial]

The HTC One X is an out and out powerhouse, and with a Tegra 3 quad-core processor as well as a beautiful, svelte design, it’s unsurprisingly one of the top choices among Android users.

Building on the success of its equally Desirable predecessor, it’s a gluttonous nugget of sheer power, and with such high-spec hardware, it figures users would want to modify and tailor the experience to the extreme. Those wishing to open their device up past HTC Sense 4.0 will be pleased to learn that the Android development community has not only managed to get CyanogenMod 9 up and running on HTC’s flagship smartphone, but also, MIUI 4.


As is often the case with the first versions, the ROMs are more than a little rough around the edges. While CyanogenMod 9 takes a while to connect to 3G, it also doesn’t support camera or Wi-Fi hotspots. It’s not all doom and gloom, however, and the developers have re-calibrated the buttons on the HTC One X enabling multitasking button to play the part of the menu button.

The leaked MIUI 4 beta for the One X is fully operational, maintaining features such as the stock HTC camera, gallery and music (including Beats Audio). If you want to install either, then check out the tutorials below.
