FEATURES - Hypernova
Everything from Flar Port (Gboost removed in favor of interactive and hotplug cpu control. Not necessary with this setup
Franco's enhanced interactive governor set to default, and with tweaked settings thanks to Dan
High performance audio (Thanks lyapota)
Unified dtb's to make work with all variants (Thanks captain_throwback)
Prima wlan driver module from HTC and prima with updates compiled with kernel (Thanks lyapota and captain_throwback)
FEATURES - Stockish
Optimized -O3 linaro 4.9.2
A couple fixes and other optimizations
1. Install zip from recovery
2. Follow the instructions, if you don't know what to do, use the pre-selected options
3. Wipe cache/dalvik cache
It is recommended to disable or increase the screen timeout in TWRP recovery. If the screen timeout is enabled in TWRP, there may be a black screen after exiting the Aroma installer. This is nothing to worry about. Simply hold power and volume down and volume up buttons until it reboots. The installation will be fine. If things get stuck in aroma, simply do this reboot method and immediately hold down to get to bootloader mode, then select recovery and start from the beginning.

NOTE: Custom wake gestures are a WIP. If you have problems with the proximity sensor, reinstall with stock gestures option
NOTES AND OTHER IMPORTANT STUFF YOU SHOULD KNOW!!!
Your choices in the Aroma installer are used to build a configuration file. The config file is located at /etc/elementalx.conf. You can edit this file to change kernel settings. Whatever is set in this file will take effect when the device is booted (unless other scripts or apps interfere!)
If settings are not sticking:[*]Make sure you have busybox installed correctly and updated to the latest version[*]Make sure the file permissions for /etc/init.d/99elementalx or 99msx are set to execute.[*]Check to see if any /etc/init.d scripts or apps (such as Kernel Tuner or TricksterMod) are interfering with your settings.
ElementalX Log File
Every boot, a log file is created at /data/local/tmp/elementalx-kernel.log or msx-kernel.log. This file shows the date and time and all settings that have been applied. Use this to verify and troubleshoot configuration options. Also, in this file is your devices PVS number. Please refer to the links down below as to what the heck the PVS means. Helps with troubleshooting OC/voltage related reboots device specific. Not all devices were created equal!
Overclocking is optional. The installer lets you choose the maximum frequency. Whatever frequencies you chose in the installer will be set at boot for each CPU. Not all devices can handle overclocking. I don't recommend overclocking, this device is fast enough. If you overclock, the CPU frequency will likely be throttled due to heat. I recommend the stock frequencies, as this device is plenty fast.
The installer allows you to choose from several undervolting options: stock, -15mV, -30mV, or -45mV. This only undervolts the lowest frequency, which happens to be the frequency used the most, and this is safer. Be careful, lowering voltages can cause instability.
gboost enhances gaming performance by giving a slight boost to cpu frequencies when the graphics load is high (e.g. while gaming). It should have no effect on battery life during regular usage, so it's safe to leave it enabled all the time.
fsync can be disabled if you're looking for the last ounce of performance. I recommend leaving it enabled as there is a slight risk of data loss if your phone shuts off unexpectedly before filesystems are synced.
Installing a new ROM
If you install a new ROM, it will probably replace this with the stock kernel and will definitely overwrite /etc/init.d/99elementalx and /etc/elementalx.conf so you will lose your settings and certain features. So always reinstall the kernel after installing a ROM.
Sweep2sleep allows you to put your device to sleep by swiping right to left across the bottom of the screen where the back, home, recent buttons are. I find this useful since the stock motion gestures do not provide a good way to turn off the screen.
1= sweep2sleep right enabled
2= sweep2sleep left enabled
3= sweep2sleep left and right enabled
USB fastcharge is optional. This will allow you to charge at a faster rate when connected to a USB port. The default limit for USB ports is 500ma, this increases it to 1100ma. Be sure that the computer/laptop/whatever you are plugged into can handle it. Some will automatically cap it at 500ma. Please note that this does not force AC charge mode like previous implementations of force fastcharge. Your battery setting will still say USB mode. You can edit /etc/elementalx.conf to change the setting on boot.
There are three modes
Mode 1: Stock Motion Launch Gestures
For stock motion launch gestures, /sys/android_touch/wake_gestures, /sys/android_touch/sweep2wake and /sys/android_touch/doubletap2wake must all be set to 0. Enabling any of these overrides the stock gestures. Obviously Motion Launch Gestures must be enabled in the system settings.
Mode 2: Remove motion requirement
For this, you must set /sys/android_touch/wake_gestures to 1 and enable at least one gesture in /sys/android_touch/sweep2wake or /sys/android_touch/doubletap2wake and Motion Launch Gestures must be enabled in system settings. In this mode, when you sweep or doubletap, the appropriate input events are generated and acted upon the EasyAccessService (i.e., the system app that handles gesture actions).
Mode 3: Traditional S2W/DT2W
In this mode, wake gestures and actions are handled entirely by the kernel. The gestures will turn on the screen and that's it. For this, you must set /sys/android_touch/wake_gestures to 0 and enable at least one gesture in /sys/android_touch/sweep2wake or /sys/android_touch/doubletap2wake. It doesn't matter if Motion Launch Gestures is enabled or disabled in system settings, the gestures don't interact with it in this mode.
For modes 2 and 3, there are several options.
Add up the values for each gesture you want to enable and put the total in /sys/android_touch/sweep2wake. For example, to enable all gestures, the value is 15 (1+2+4+8). To enable sweep right, sweep left and sweep up, the value is 7 (1+2+4)
Set /sys/android_touch/doubletap2wake to 1 to enable DT2W, and set to 0 to disable it.
Set /sys/android_touch/pocket_detect to 1 to enable pocket detection, and set to 0 to disable it. Pocket detection is experimental right now, I'd say it's about 90% functional, but there is an occasional bug where it either doesn't work or works too well.
Haptic feedback can be enabled for the wake gestures in /sys/android_touch/vib_strength. This setting takes a number between 0 and 60. Default is 20, which is the same vibration as the stock gestures. Setting this to 0 disables haptic feedback.
