Thanks to those who have donated!
1. Install zip from TWRP Recovery
2. Follow the instructions, if you don't know what to do, use the preselected option
First boot will take a while. Let it load all the way, then let it settle in for a few minutes, then reboot again.
Q. I installed ElementalX and now I'm stuck in a bootloop
A. Go to this thread and get S-OFF: http://forum.xda-developers.com/show....php?t=2155071
Q. I installed ElementalX and now my phone is laggy/sdcard is corrupt/camera doesn't work/other random problem not related to the kernel
A. Please don't fill up my thread with vague complaints. As long as you pick reasonable voltage and frequency settings, this kernel is 100% stable and problem free. I know what I'm doing and I don't do anything to the kernel that will mess up your phone. If you have problems, it's because of something else you've done. If you think you've found a bug with the kernel, please include dmesg output or /proc/last_kmsg
Q. I installed ElementalX and I get random reboots
A. If the reboots occur when your phone is idle, increase your voltage or increase your max screen off frequency. If the reboots occur while you are using the device, scale back your overclock and/or increase voltage. If all else fails, choose the vanilla option.
Q. What if I am still having problems?
A. If you are having problems the key to getting help is to provide appropriate detail.
Number 1: Description of your issue
I'm most cases people in this thread will try and help you. The more information, the better chance someone in the thread will be able to help you.
If you can't be helped by one of the experienced ElementalX users it would generally be referred to the dev
Number 2: Details of installation options e.g.
- ElementalX 6.5 Vanilla
- CPU Max: 1.7ghz
- CPU Min: 384mhz
- GPU OC: On
- S2W: On
- fsync: On
- Zram: On
Number 3: Logs, refer to the following details on gathering appropriate logs
In the below example the adb path is c:adb
Open command prompt type cd c:adb
The following two commands can be used to provide logs to help troubleshoot slowdown/freezing issues.
adb shell top -n 1 > c:top.txt
adb shell dmesg > c:dmesg.txt
If you experience a non-user initiated reboot please follow the below steps to provide last_kmesg
* After reboot issue is encountered boot to recovery
* use the file manager to copy /proc/last_kmsg to sdcard/download/
* mount usb and copy it to your computer
* zip it
* post it with details of your issue in this thread.
* restore your nandroid and boot into your last stable config

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!)
The settings can be changed by editing /etc/elementalx.conf and rebooting. Advanced users can apply settings on the fly by running /etc/init.d/99elementalx as root.
There is no need to edit /etc/init.d/99elementalx. All settings are configured in /etc/elementalx.conf.
If settings are not sticking, make sure the file permissions for /etc/init.d/99elementalx are set to execute. Every time the settings are applied, a log file is created at /data/local/tmp/elementalx-kernel.log. Problems can be diagnosed by looking at the log file.
Please check to see if any /etc/init.d scripts or apps are interfering with your settings If you're on ViperXL, make sure your settings in Venom Tweaks are the same as the ones in /etc/elementalx.conf (for example, sweep2wake settings)
You don't need Kernel Tuner because the ElementalX installer sets everything up automatically, but if you want to check or change settings, Kernel Tuner is recommended. Just be aware that Kernel Tuner is set by default to apply settings on boot, which can interfere with the settings you chose in the ElementalX installer.
Venom Tweaks force close
If Venom Tweaks closes when you try to access the CPU tab, go to Settings->Apps->Venom Tweaks and push the Clear Data button. This should fix the problem.
Vanilla: stock voltages, stock l2 cache frequency, stock bus bandwidth
ElementlaX: increases l2 cache frequency and bus bandwidth, allows you to choose voltage level in installer
Ultra: increases l2 cache frequency and bus bandwidth even more. May cause instability, please test thoroughly for stability if you use this option.
Overclocking (underclocking) is optional. Whatever frequency you chose in the installer will be set at boot for both CPUs. Frequencies can be changed any time using apps like No Frills or Kernel Tuner. WARNING: not all devices can handle overclocking. The stock maximum CPU frequency is 1.5GHz. In versions of the kernel prior to 6.4, the frequencies were labeled wrong so you won't be able to overclock as high with version 6.4+.
CPU voltages can be changed with Venom Tweaks, Kernel Tuner or System Tuner. Be careful, lowering voltages could cause instability. If you have stability problems even at the highest voltages, try the vanilla version
Minimum CPU frequency
Sets the minimum CPU scaling frequency. 192MHz is the recommended default and should work fine on the vast majority of devices. The 384MHz option is available for devices that experience random reboots while the device is idle. It is recommended that you try increasing the minimum voltage by 25mV before changing the minimum CPU frequency.
Max screen off frequency
This sets the highest CPU frequency available while the screen is off. It is recommended to disable this for stability. Also, do not set this to 192MHz or 384MHz, as many devices experience random reboots at these frequencies. The default is 486MHz, which should be safe for most devices. If you experience random reboots while the device is asleep, set this to a higher frequency. This setting can be changed in /etc/elementalx.conf or using an app like Venom Tweaks.
3D GPU: 480 (overclocked) or 400 (stock)
2D GPU: 266 (overclocked) or 200 (stock)
Intellidemand is the default CPU governor. There are other governors included, however, intellidemend is recommended for best balance of battery life and performance.
Installing a new ROM
If you install a new ROM, it will overwrite /etc/init.d/99elementalx and /etc/elementalx.conf. The kernel will run perfectly fine without these files, but you will lose your settings and certain features.
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). There are now options for sweep2wake/sweep2sleep, sweep2sleep only, and disabled. If you use ViperXL, make sure to enable sweep2wake in Venom Tweaks.
1=enable sweep2wake + sweep2sleep
2=enable sweep2sleep only
DoubleTap2Wake (DT2W) allows you to wake the device by double tapping in the bottom inch or so of the screen, including the capacitive buttons. You can edit /etc/elementalx.conf to change the setting on boot.
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.
1=enable pocket detection
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.
0 = disabled
1 = BLN enabled
What is zRam
zRam creates a compressed block device in RAM that is used as swap. Although it claims some of your RAM as swap, everything written to swap is compressed. This increases the apparent memory available to the system and helps with multitasking. Swap files on disk are very slow, but with zRam the swap is on RAM so it can be read as quickly as regular memory. Even though the data need to be decompressed, modern CPUs can decompress quicker than if it had to be to read from disk. The penalty is cpu usage, which could drain battery; however, this is likely negligable in daily use. I didn't enable this by default because not everyone will want it. This is for heavy multitaskers and will allow you to quickly switch between more apps and have more tabs open in your browser without refreshes.
zRam is disabled by default. If you want to enable it, edit /etc/elementalx.conf
change ZRAM=0 to ZRAM=1 and reboot.
You can check if zRam is working by typing the command "free" into the terminal. You should see the total used and free swap. If these are all 0, then zRam is not enabled. Please ensure that other apps are not changing your minfrees, zRam works best with low minfrees and high swappiness.
This is for anyone who wants to use OTG to connect a USB stick or portable harddrive formatted with Microsoft's NTFS filesystem. You will need Stickmount or a similar app, HTC Sense+ won't detect NTFS.
Disabling fsync can increase filesystem performance. However, there is a small risk of data loss if the system suddenly crashes. If you can't afford to lose data, keep fsync enabled. Many custom kernel disable fsync, I leave it enabled by default for safety reasons.
XBox controller support
There is an experimental module that supports XBox gamepads, however, some people have reported that it draws too much power and doesn't work. I've suggested trying a powered USB hub, but still not sure if it works.
