[Custom Kernel] ZenfoneIndia2X-4X KERNEL ver 6

Credit to Vipin Arumugham / http://www.toonsters.com/zenfone-custom-kernel

**** ZenfoneIndia2X-4X KERNEL ver 6****  
Custom kernel for battery boost  
Created by Vipin Arumugham

Compatibility

- Zenfone 501CG/T00J and 500CG/T00F with WW Firmware
- 2.20.40.30 and 2.21.40.30 WW Kitkat Version
- AOSP ROM by Shakalaca
- Custom Rom Zenfone 5 PinasLang BazzROM

Features of the "ZenfoneIndia2X-4X Kernel V.6

1. 2 CPU cores are switched off when screen is off instead of 3 cores but CPU boostpulse has been reduced for better deep sleep.
2. By Default 2 CPU Cores are disabled with minor loss in performance.
3. Use this mode for Browsing ,Whatsapp, facebook, music,messenger apps etc apps which don't need heavy processing.
4. Games are still running smoothly.
5. Camera works. (HDR MODE needs 4 cores)
6. IMPROVED BATTERY.
7. IMPROVED SMOOTHNESS IN TRANSITIONS.
8. IMPROVED FREQUENCY SCALING.
9. IMPROVED DEEP SLEEP BATTERY SAVING.
10. You can manually activate 4 CPU cores for higher performance.

*NEW CHANGES*- "HOW TO SWITCH BETWEEN 2 CORES AND 4 CORES"

To enable and disable 4 cores :

Turn off screen and wake up after 3 seconds (DO IT TWICE)

[ eg: Turn off screen and wake up after 3 seconds...

..Turn off screen again and wake up again after 3 seconds ]

- 4 cores get enabled after you do the above. If you repeat the same process it
comes back to 2 cores.

In 4 cores mode: When screen is on 4 cores are active, Screen off sleeps to
2 cores in low CPU boostpulse mode. But it always wakes to 4
core mode.

In 2 cores mode: When screen is on 2 cores are active, Screen off sleeps to
2 cores in low CPU boostpulse mode and wakes to 2 cores only.

**The above is to prevent any accidental activation or deactivation of cores.**

- Do it before starting heavier apps or games if needed.
- Don't do it while heavy apps/games are already running.
- If you switch off screen again it sleeps to 2 cores but will always wake up to 4 cores until you disable 4 core mode.

4. Stability issues and hanging issues of version 5 fixed. SD CARD issue fixed.

The boot up process and bootanimation is slow. Switch off screen once after the boot up process to remove any lag.

KEEP GOVERNOR as INTERACTIVE if you have rooted your device. Uninstall CPU controlling apps and reboot. Xposed modules and gravity box may interfere with the smooth function.

------------------------
Results
- Improved battery backup
- Better Deep sleep battery saving.
- Better CPU core switching.
- Slight loss in performance.

**SD CARD ISSUE FIXED**
