Q: What ROMs are supported?
A: Custom Roms with and without Treble Support and Stock Roms

Q: Do my Soc will be damaged if i use OC?
A: No,All values are tested and safe

Q: What Governor to choose?
A:Read about them below


A highly modified interactive-based governor with the intention of giving the user more control by providing more tuning options. Based on CAF 4.4 commits with parts coming from blu_active and XDA user Sultanxda.


The ZZmoove Governor by ZaneZam is optimized for low power consumption when the screen off, with particular attention to the limitation of consumption applications in the background with the screen off, such as listening to music. The unique feature with ZZmoove is that it has predefined profiles and allows profile switching.


A governor developed by eng.stk (featured in his Code_Blue kernels) based on interactive with upstream caf patches and ondemand governor bits too. This governor is mainly focused on performance like the other things the developer creates but it is also well balanced for gaming and general usage.


An improved version of interactive modified by neobuddy89. Impulse aims to have a balance between battery and performance just like interactive but has some tweaks to save battery.

    Please stop asking for ETAs (estimated time of arrival), this ALWAYS ends badly for everyone. Asking for ETAs is considered disrespectful towards the devs because it pushes them for nothing. Remember they are providing their work here for free, on their free time, so it means what's coming next will be available...when done.

    Also, please stay civil any time, if a post bothers you, you just need to ignore and use the report button, then the moderation team will handle the situation accordingly.

    A few recommendations to have maximum battery life with the highest performance possible (if demanded by an app / game / etc.):

    1) Install Extreme Kernel V4
    2) Install Kernel Adiutor from Play Store
    3) Set this:

    Under "CPU":
    "Apply on Boot" Enabled
    "Schedule workqueues on awake CPUs to save power." Enabled

    Under "CPU Hotplug"
    "Apply on boot" Enabled
    "AutoSMP" Enabled
    "Screen off Single CPU" Enabled

    Under "I/O Scheduler"
    (CFQ is best the best scheduler, tested this with PC Mark and all the others, including Maple and especially BFQ did worse than CFQ! Also increasing the buffer size > 512kB gave no performance improvement either)
    "Apply on boot" Enabled
    "I/O Stats" Disabled (could be several entries, set all to Disabled)
    "Add Random" Disabled (could be several entries, set all to Disabled)

    Under "Misc"
    "Apply on boot" Enabled
    "Fsync" Disabled

    Enjoy max performance and max battery life :)
    Is clean install required? I am now in Ex V7

    ? this is daniel. He does not quote whole OP to rasie a doubt. If he has concerns he simply posts a question. Daniel is smart. Be like " Daniel"
