Well, it seems its about time I release one of the most awaited thing (after a long long time) for this device.

Presenting you with a piece of real dev (kinda), Zapdos Kernel.

Features

Compiled from source.

Compiled using ARM official toolchain (4.4.3).

Bootable on ALL firmwares. This removes the distinction between 'old' and 'new' firmwares.

Swap Support. You got that right, swap support on your favorite ROM, regardless of it being 'old' or 'new'.

CPU Frequency Scaling. Apps like CPU-Z and others will now show more details than ever.

1400 Mhz Overclock.

Governors enabled.

More Governors added.

CPU Idle Power Management Support.

More CPU Frequencies.

Modified Voltage table for better battery life. [UPDATE]

Settings -> Battery, will now show battery usage by apps too. Partially fixed in v2.0 Update.

More I/O Schedulers.

Dynamic Read Ahead Support.

Dynamic Fsync v2.0. Gives massive boost in I/O Performance, and is reflected in benchmark. (Thanks to Faux123)[UPDATE]

Added Double Tap 2 wake feature.

Added bunch of TCP Congestion Controls.

Added Mali GPU profiling.

Based on gzip compression method.

Insecured boot.

Easy root enabled.

Bunch of corrections.

Uses Custom boot splash.

Added VR I/O Scheduler. [NEW]

Added Zen I/O Scheduler. [NEW]

Added TripnDroid I/O Scheduler. [NEW]

Added FIFO I/O Scheduler.[NEW]

In-app updates. [NEW]

Disabled Gentle Fair Sleepers. [NEW]

Asynchronous I/O latency to a solid-state disk greatly increased.. [NEW]

NOATIME and NODIRATIME by default. [NEW]

Disabled CRC check. [NEW]

Optimized SLUB. [NEW]

Optimized Square root algorithm. [NEW]

No dirty things in kernel version. [NEW]

Bugs/Glitches

It is highly likely to experience bugs and glitches, because CPU frequency is enabled. Samsung had disabled it for stability issues.

After reboot, battery remaining value drops drastically, but will increase back eventually to normal, its a glitch, not a bug.

Attaining CPU frequency scaling like other Android Phones is difficult, real-time CPU Frequency scaling isn't possible because, if tried, results in crash.

Broken battery usage by all apps after overclock. Partially fixed in v2.0.

DoubleTap2wake is experimental, it sometimes does not work by name (i.e you need to tap more than 2 times, but it will work for sure).
