Q. How to install?
Just as you install a custom kernel.
Steps:
1. Power down device and get into FASTBOOT MODE -> switch off device hold menu key & plugin usb. (LED notification turns BLUE)
2. check fastboot with "fastboot devices"
3. flash boot image
fastboot flash boot boot.img
4. Reboot with "fastboot reboot"
5. Enjoy!
How to enable/disable features?
This kernel sets properties to features so that they can be enabled or disabled easily
Code:
shardul.module.tun=0
shardul.module.isofs=0
shardul.module.ntfs=0
shardul.module.hid_apple=0
shardul.module.hid_microsoft=0
Method 1: Edit /data/local.prop directly
Method 2: "writeprop shardul.module.isofs 1" on shell / terminal emulator for individual properties set/unset
Module will be loaded on next boot!
If you want to load module only for the current session, see this app!
Q. How to undervolt (UV)?
Easy methods -> andrev_oc, IncrediControl (Thanks to adridu for the tip)
OR
Query vdd levels (output: first column: frequency (kHz), second column: vdd* (mV))
Code:
cat /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
incrementing/decrementing all levels by a specified amount* (mV):
Code:
echo '-25' > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
echo '+25' > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
adjusting the supply voltage* (second value, mV) at a specific frequency (first value, kHz):
Code:
echo '998400 1250' > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
*: vdd values must be a multiple of 25 (enforced by the interface; the regulator doesn't accept other values)
Want this on locked bootloader? : See here

Nice to see some new stuff...
Your writeprop script is well done BTW I might take it for my next release.

Is this better than the superstock kernel?

---

Awesome! Will try it as soon as I get my hands on a computer. Mine is broken right now.
Sent from my MT11i using xda premium

thanks shardul., il try it.,

Flashed...
Wifi-OK
Cam-OK
BT-OK
Video Play-OK
U-Totta OK..!!
Battery Drain to be tested..
Problem-This doesnt supprt Undervolting???
i want this feature..it really helps in battery use..
Will give a better feedback tommorow..
Charging the phone..

great work thank you
is there any way to increase amount of ram to 340 mb as G.B kernel

---

It is already 340 mb. Please check.
It can be increased more by reducing camera memory, but that may make the camera unstable!

---

Can I use this kernel with MIUIv4 (ICS) EN 2.6.8 for Neo V?

Yess u can...
@shradul- Very High Sleep drain... lost 10% in 5 hrs... i hope it will become more stable with tym and ur expertise..
Waitng for vdd..

---

@ALL:
1. I have noticed that v6 supercharger script adds "pm.sleep_mode=1" in build.prop
This causes high drain on some networks in sleep.. Just remove that line after install v6 supercharger script by zeppelinrox
2. If data is on overnight, it uses a lot of battery.. Use any script or app to turn off data when not required

See OP, updated

---

How I can test that is my phone will be stable with new voltages?
Sorry for my English.

Did you even read the OP?
There is a section on how to undervolt!!
@kibol44: Values are reset at boot.. So try low values (individually for all frequencies), if phone freezes or random reboots, then you are too low . After you have found the correct values for your phone, you would need an init.d script for setting values on every boot..
@ALL: 2-way call recording, some debugging features turned off (logcat is still enabled), VM readahead increased, NFS (which i dont think anybody uses, but available as module) turned off for better battery..
My phone running stable on it since the last 4 hours. Anyone else who is willing to test?
