INSTALLATION
1. Install zip from recovery
2. Follow the instructions, if you don't know what to do, use the preselected options
3. Reboot
For installation, it seems a lot of people have finicky phones when it comes to flashing stuff with aroma.
If the installer gets stuck at 0% then you need to reboot to bootloader and do fastboot erase cache
If the installer reboots at 10%, you need to do a nandroid backup of /system partition and restore it. I think a dirty flash would also work.
After you install it, if you get a black screen or stuck at the HTC logo, no need to worry. Just hold down the power button untill the capacitive buttons start flashing and the phone restarts. The kernel installed correctly.
As always, with overclocking, not all phones can handle all frequencies. If it doesn't boot, or randomly reboots, or freezes, your first course of action should be to reinstall with a lower frequency.

ElementalX Log File
Every boot, a log file is created at /data/local/tmp/elementalx.log. This file shows the date and time and all settings that have been applied. Use this to verify and troubleshoot configuration options. Also shows your PVS bin.
Kernel Tuner/TricksterMod/Venom Tweaks, etc
You don't need these apps because the ElementalX installer sets everything up automatically, but if you want to check or change settings, you can use these apps. Just be aware that some of them (e.g. Kernel Tuner) are set by default to apply settings on boot, which can interfere with the settings you chose in the ElementalX installer.
Note: on the most recent versions, fauxclock interferes with GPU overclocking unless you disable pnpmgr (not recommended)
Overclocking
Overclocking (or underclocking) is optional. The installer lets you choose a maximum between 1134MHz (underclocked) and 2160MHz (overclocked). You can set the maximum frequency individually for each CPU core in the installer. Whatever frequencies you chose in the installer will be set at boot for each CPU. Not all devices can handle overclocking. The stock maximum CPU frequency is 1.7GHz. I recommend a mild overclock, like 1836MHz. Clocking higher creates heat and wastes battery for very little performance gain.
CPU voltages
The installer allows you to choose from several undervolting options. These automatically undervolt the lowest frequency (384MHz) where the CPU spends most of its time. The voltages for other frequencies are assigned based on the PVS bin of your phone. CPU voltages are fully customisable with apps such Kernel Tuner or Trickster Mod, but I recommend leaving these other voltages as-is unless you are prepared to do a lot of testing. Be careful, lowering voltages can cause instability. Generally, having reboots while the phone is asleep is a sign that your minimum voltage is too low. The minimum voltage allowed is 700mV.
Be careful with undervolting. If you have bluetooth or sound issues, try increasing the minimum voltage.
Minimum CPU frequency
The minimum CPU frequency in this kernel is 384MHz. This chip was not designed to operate below 384MHz and I am respecting Qualcomm's design decision to have the CPU idle on pll8 at 384MHz. There is a way to achieve lower frequencies using the high frequency pll, however, this is likely to cause instability and inefficient operation (battery drain, ui stuttering)
GPU frequencies
You can choose stock GPU frequency of 400MHz or overclock. If overclocked, you can choose from a range of frequencies up to 585MHz. Overclock frequencies can be changed on the fly, but you can't use the stock frequency. Conversely, if you choose stock GPU, the overclocking frequencies will not be available. To change between stock and overclocking mode, you need to reinstall. The same voltages are used no matter if the GPU is overclocked or not.
GPU Governor
The default GPU govenror is ondemand. It works well and is recommended for best balance between performance and batter life. The simple governor is also available, but ramps up the GPU frequency much quicker than ondemand, so may impact battery life. The governor can be set in /etc/elementalx.conf
Thermal Control
I've added kernel based thermal control and throttling. HTC's thermald is very aggressive and throttles the CPU frequency pretty much anytime you use all four processors. This kernel based implementation allow better performance while still protecting your phone from overheating. There are three levels of thermal control, which can be chosen in the installer or changed in /etc/elementalx.conf. The default option is recommended. With the run cool option, your CPU will run about 5C cooler than default while under heavy load. With the run hot option, the CPU will run about 5C warmer than default under heavy load.
MPDecision settings
There are three mpdecision settings available: battery saving, stock and performance. I think they are self explanatory. These can be changed in /etc/elementalx.conf
Max screen off frequency
This is optional and must be selected in the installer. I recommend enabling it. This limits the max cpu frequency while the screen is off. The default max screen off frequency is 702MHz, which is a good balance between limiting the voltage/frequency and the time required to complete tasks while the screen is off. You can adjust this with applications such as Venom Tweaks.
I/O Schedulers
The default i/o scheduler is ROW. Other available schedulers are ROW, CFQ, FIOPS, SIO, NOOP and deadline.
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.
Sweep2Wake
Sweep2wake (S2W) allows you to wake up your device by swiping your finger across the capacitive buttons from left to right. Swiping from right to left will put it back to sleep (sweep2sleep). The options are: sweep2wake/sweep2sleep, sweep2sleep only, and disabled. If you use apps such as Kernel Tuner, the sweep2sleep only option can be selected by choosing "On with backlight". You can edit /etc/elementalx.conf to change the setting on boot.
/sys/android_touch/sweep2wake
0=disabled
1=enable sweep2wake + sweep2sleep
2=enable sweep2sleep only
DoubleTap2Wake
DoubleTap2Wake (DT2W) allows you to wake the device by double tapping in the bottom inch or so of the screen, above the capacitive buttons. You can edit /etc/elementalx.conf to change the setting on boot.
/sys/android_touch/doubletap2wake
0=disabled
1=enable doubletap2wake
Logo2Wake
Logo2Wake (L2W) allows you to sleep or wake the device by long pressing the HTC logo. You have to press just slightly above the HTC logo. The screen will automatically turn on or off with a long press. You can edit /etc/elementalx.conf to change the setting on boot.
/sys/android_touch/logo2wake
0=disabled
1=enable logo2wake
Pocket Detection
Pocket detection protects against accidental wakes while S2W, DT2W or L2W are enabled and the phone is in your pocket. Pocket detection uses the proximity sensor. A few people have a problem with their proximity sensor that makes DT2W not work, so I've made an option to disable pocket detection. You can edit /etc/elementalx.conf to change the setting on boot.
/sys/android_touch/pocket_detect
0=disabled
1=enable pocket detection
Logo2Menu
Enabling Logot2Menu (L2M) allows you to use the HTC logo as a menu button. You must press just slightly above the HTC logo. You can edit /etc/elementalx.conf to change the setting on boot.
/sys/android_touch/logo2menu
0=disabled
1=enable logo2menu
Button Light Notification
With Button Light Notification (BLN), the capacitive buttons will blink on and off when you have a new notification. As soon as the screen comes on, BLN is canceled and the lights will no longer blink until you have another notification. Please note that if you have your screen set to turn on when a message arrives, you will not see the buttons blinking because once the screen comes on, the button light notification is canceled. You can edit /etc/elementalx.conf to change the setting on boot.
/sys/class/leds/button-backlight/blink_buttons
0 = disabled
1 = BLN enabled
NTFS and exFAT support
This is for anyone who wants to use OTG to connect a USB stick or portable harddrive formatted with Microsoft's NTFS and exFAT filesystems. You will need Stickmount or a similar app, HTC Sense does not automatically detect these filesystems.
Other stuff
This kernel supports many game pads and controllers, including PS3 controllers and some X-Box controllers. It has full OTG support. A refresh rate of 60Hz for HDMI output allows you to play games on the big screen without choppiness. CIFS support is built into the kernel. Faux sound and color control are also supported.
