It shouldn’t take long now for the official Android 4.1 update to hit the HTC One X, but if you feel like you simply can’t wait anymore there is one way to flash a rather stable unofficial Jelly Bean port on your phone.

Recognized XDA contributor Football has posted the custom ROM just hours ago, but it already looks like one of the safest ways of getting an early sneak peek at Jelly Bean. There is one simple explanation for the port’s stability, with Football claiming that this is actually a leaked software package based on the shipping software of the soon to be released One X+.

Unfortunately, the maXimus v4.1 ROM with Android 4.1.1 and HTC Sense 4+ can only be flashed on certain versions of the international model of the One X. More precisely, you shouldn’t be trying out the firmware if you don’t have a One X powered by NVIDIA’s Tegra 3 quad-core processor and if your CID number is not one of the following:

  • cidnum: HTC__001
  • cidnum: HTC__E11
  • cidnum: HTC__203
  • cidnum: HTC__102
  • cidnum: HTC__405
  • cidnum: HTC__Y13
  • cidnum: HTC__A07
  • cidnum: HTC__304
  • cidnum: HTC__M27
  • cidnum: HTC__032
  • cidnum: HTC__016
  • cidnum: HTC__J15

Now if you are one of the lucky owners of a “select” One X that can safely run the Jelly Bean-based custom ROM, you should take a very close look at the installing instructions at this link (right beneath the download). The usual set of precautions applies too, so be sure to back up your data before flashing and don’t forget that you’re pretty much guaranteed to void your phone’s warranty if you flash a custom ROM.

You’re also in danger of not receiving official OTA (over-the-air) updates if you root your device, so there’s plenty to make you think twice before installing this leaked upgrade.

Then again, there is plenty to make you want it too, with most “testers” saying that the update feels just like an official one, making the phone “blazing fast” immediately upon installing. And if you prefer numbers over words, how about a 13,000 score in AnTuTu and a 7,000 in Quadrant for the One X with Jelly Bean?

All things considered, are you thinking of trying out the update or will you wait for the officially official one? How about the One X+, is anyone with an original One X considering upgrading?
