HTC One X Unlocked gets Official Android 4.1 RUU

December 10, 2012 - Written By Alexander Maxham

If you own the Tegra HTC One X, you’re probably asking HTC and everyone else where your Jelly Bean update is. It’s already started rolling out in parts of Asia, but it hasn’t made it to the rest of the world yet. And those on AT&T, you probably won’t see it for a few more months unfortunately. Although for those with the Tegra 3 version of the HTC One X, an official RUU was published by HTCRUU which will bring your software to versions 3.14.401.27. Which includes Android 4.1 and Sense 4+.

Before we get to the download links, this is only for certain variants of the One X. So if you see your CID number below, then you can use this RUU to flash Android 4.1 onto your device. Note: this is NOT for the AT&T One X. Here are the CID’s:


So how do you find out your CID? Simple. Just boot into fastboot mode on your One X, hook it up to your computer via USB, and run “fastboot getvar cid”. I know it sounds complicated, but actually isn’t. If you need some assistance, there’s a nice tutorial over on XDA that explains just about everything.

Just download the firmware, boot your phone back up again with USB debugging enabled in fastboot mode, run the file, and follow the instructions. Pretty easy. Be sure you have the drivers installed first though.

It’s important that we stress that if your CID is not listed above or you have a LTE One X, that this RUU will NOT work with your device. So if you try to use it and mess up your device we are not responsible for any damage caused and have warned you. With that said, try it out, give us feedback below as to how it went for you. Also let us know how you like Jelly Bean and Sense 4+.
