AT&T has just started rolling out the Android 4.1 Jelly Bean Jelly Bean Update to the HTC One X. Owners of this device will definitely be pleased with the various improvements brought by this update which already went live a month ago to international users of the One X.


Some of the most notable features brought by this update are

  • Changes to the notification display that groups updates from the same application together and allows you to expand or collapse any notification.
  • The ability to view the full text of an SMS message and the full photo of a MMS in the notification window.
  • An event notifications display that offers more of the event description, allowing you to quickly see relevant details without having to open an app.
  • New countdown timer for the front-facing camera.

To get the update you will just have to go to the “About Phone” section and click on “Check for Updates” to see if it has already rolled to your device. If it isn’t available and you can’t wait for it to arrive you can manually install it.

  1. Call ATT ask for tech. You might have to call a couple times because they all dont know. They can attempt to push it to your phone. If that does not work, you need to back up your phone. Go to download htc sync minimze it then back up to main page pick your device in this case ATT HTC ONE X near the to of page right hand corner download update its called evita I dont recall the whole file name. But it is only one, once downloaded plug in your phone and follow the instructions its all automatic. I would suggest having tech walk you through it. Not required but to make sure you dont run into a problem and have an issue. I did this todaY AND EVERYTHING IS WORKING GREAT. Its really easy but like I said for peace off mine have ATT tech support walk you through it .

  2. Red triangle with exclamation mark then this appears on the screen.

    E:Can’t open /cache/recovery/command
    E:failed to mount /sdcard (no such file or directory)

  3. Same here, /sdcard can’t mount. Every user who tried this in AT&T forums gets same issue. Maybe test a procedure before giving instructions?

  4. Its not working for me, just says Sdcard it doesnt mount. !!!!!! wow how you did ? Please let me know
