Install Android 4.2.1 AOKP Jelly Bean On HTC One X

HTC One X users can now install Android 4.2.1 AOKP Jelly Bean via Custom ROM ColdIceJelly. HTC is yet to roll out official Android 4.2.1 for One X. Let us go through the guide to install Android 4.2.1 AOKP on HTC One X.

Remember that this is a Custom ROM and not an official update by Google or HTC. The ROM is in development stage and not all AOKP features have been ported to 4.2.1.

What’s New

Wlan tether now has working security network mode
Added Hardware keys mapping (Settings/Display) – thanks to maxwen for porting the fwb part

Fixed Taking photos while video recording (1080p has some issues) – maxwen
Added MenuUI overflow button – AOKP
Fixed Long Press Back button functionality – maxwen again
Using prebuilt camera lib, not building it from HAL anymore
Added back Powermodule HAL to the build – needs testing
Added Button Notification Light option (Settings/Display)
Interactive set as default governor – don’t change it if you love your phone
Used Calculator app repo from CM
Added a bunch of new options to Camera from CM (lost 2 days to get it working)
updated kernel with BT drivers to 3.1.10 ; integrate some tegra references patches for BT
Added CPU boosting modifications from CM
Fixed some bugs under the hood – AOKP and CM
Battery should be improved in this version, expect 2h of screen ON while browsing for sure!
This rom still isn’t where I want it to be – will start to add more options to the rom soon

What’s Broken
everything that is mentioned in TeamNDVRu’s thread:

A2DP for BT still has some issues
WiFi direct
In call volume adjustment works, but not fully well in Speaker mode
MHL output is rotated incorrectly to portrait in horizontal mode (but workaround added since alpha 8 for hw decoded videos/youtube. Use bsplayer from playstore, almost all videos play with it in correct rotation in hwoverlay)
No FM radio app in ROM. But Spirit FM works from market (it’s commercial!)
Probably some more stuff
