[ tips / recommendations ]

for optimal results it is HIGHLY recommended to use -36 baseband with corresponding libs...

for better battery life try undervolting... start off in steps of -25mV and see which is stable for u... for my PLAY -100mV was stable...

before u report any battery drain issues please read this:

[GUIDE] HOW-TO Properly Evaluate Battery Life and Provide Useful Reports

[ intro ]

hello ppl!

this kernel is for stock SE 4.0.2.A.0.42/.58/.62 FW...

for older kernel versions for older FW refer to following:

Older Releases [FW: 4.0.A.2.368]

Older Releases [FW: 3.0.1.A.0.145/146/148]

Thank you robytigers , Adam3Sixty, The_Gatekeeper_, Flava0ne, dannejanne, drunkenfcuk, covux, Logseman & hayabusa08 for u kind donations :)

[v14 onwards] added Fugeswap to lowmemorykiller (thanks to LeeDroid-)

[v14 onwards] removed GPU overclock

[v14 onwards] bootup CPU frequency fix-up now at kernel level so no more need for having two separate versions of same kernels (1.6 GHz and 2.0 GHz), both are now merged into one :D

[v14 onwards] merged 4.0.2.A.0.58 & 4.0.2.A.0.62 FW kernel sources (not really any major changes)

[v13 onwards] reverted back to my stable 2.6.32.9 kernel source

[v13 ] blind testing GPU OC

[v11-BootManger-v2 onwards] added BootManager v2.0 to kernel ramdisk

[v11-BootManger-v2 onwards] added GPU overclocking! -raised lower GPU clock to 245 Mhz (initially 192 Mhz) & upper GPU clock to 365 Mhz (initially 245 Mhz)

[v11-BootManger-v2 onwards] reclaimed additional 2MB RAM from unused parts... Thanks to jerpelea

[v10-modCWM-v5 onwards] fixed busybox issue - if the user has installed busybox in /system/xbin/ then that busybox will be given preference over busybox at /sbin/

[v10-modCWM-v5 onwards] added my team's (Team UtterChaos)

FULL TOUCH RECOVERY

!!! (more details here)

[v10 onwards] changes in cpufreq driver & cpu freq table

[v10 onwards] disabled NFS/CIFS - this was causing increased battery drain in new kernel sources

[v09-tests onwards] testing battery drain issue

[v08-modCWM-v04 onwards] updated recovery to modCWM-v04 TouchEdition Recovery

[v08 onwards] added I/O scheduler: Simple I/O (sio)

[v08 onwards] added SLQB memory allocator (and set it as default)

[v08 onwards] added TinyRCU along with fixes (and set it as default)

[v08 onwards] some patches to fix kernel memory leaks

[v08 onwards] minor fix to display the kernel version info correctly in "About Phone"

[v08 onwards] added some mounting tweaks

[v08 onwards] added some tweaks for sdcard performance, Virtual Memory teaks, task killer tweaks

[v08 onwards] added support for userinit scripts:

if sd-ext is mounted then it will execute /sd-ext/userinit.sh & shell scripts in /sd-ext/userinit.d/ folder

also scripts in /data/local/ will be executed... it will execute /data/local/userinit.sh & shell scripts in /data/local/userinit.d/ folder

[v07-BT-fix onwards] fixed the issue: BT & Wifi dont work simultaneously

[v07 onwards] minor changes in my modified CWM recovery (modCWM-v3)

[v07 onwards] major cleaning of kernel sources (cleaned defconfigs using FXP defconfigs as reference)

[v07 onwards] TESTING: reverted some changes in kernel sources to older FW kernel sources to test if the issue of increased battery drain is resolved

[v07 onwards] compiled using newest gcc-4.6.2-(2011.10) linaro toolchain with O4 optimizations

[v07 onwards] changed kernel version string to "-DooMKernel" (will require specific modules for wifi)

[v06-modCWM-v2 onwards] LOTS of changes in my modified CWM recovery

[v06 onwards] shifted to 4.0.2.A.0.42 kernel sources

[v06 onwards] now using my own modified version of CWM recovery with "Fix Permissions" and "Partition SDcard" support and some cleanup in menu (for ease of use)

[v02 onwards] improved init.d support, now scripts in /system/etc/init.d will automatically be given correct permissions and be executed (this will not correct/fix the errors which might be inherently present in the script)

[v02 onwards] corrected VDD control to show only those frequencies which are enabled in CPU-freq table

[v02 onwards] autorooting (prerooted)

su binary & superuser.apk will automatically be installed by kernel :D (thanks to Bin4ry for posting the file RootXperia.zip; i have used the superuser files from his zip)

[ NOTICE ]

since i have changed the kernel version string stock wifi modules will no longer work on my kernel...

if u try to enable them on new kernel (v7 onwards)

u will get "ERROR" while starting WIFI

...

i will be providing wifi modules for my kernel which HAVE TO BE FLASHED VIA RECOVERY for wifi/bt to work correctly

stock wifi modules will also be provided which again will have to be flashed via recovery if u want to return to stock kernel OR if u revert to older v06 or lower kernels

remember i have already told this to u guys... if i see some users reporting that wifi is giving error because u did not follow my instructions ur post WILL BE IGNORED....

details regarding recovery and how to enter recovery

[ how to install my kernel (v07 onwards) ]

download the boot.img & wifi modules update.zip

save the boot.img in the folder with fastboot binaries (fastboot.exe files)

save the wifi modules update.zip to sdcard (on phone)

power down device

start device in fastboot mode

use the following command to flash the boot.img

fastboot flash boot boot.img

reboot phone and enter recovery

flash the wifi modules update.zip for my kernel

reboot phone and enjoy the kernel ;)

[ how to get back to stock kernel OR older versions of my kernel (v06 and lower) ]

download the stock wifi modules update.zip

extract the kernel.sin (or boot.img if u want to flash my older kernels) file from the stock FTF u used to flash this fimware

save the kernel.sin (or boot.img if u want to flash my older kernels) in the folder with fastboot binaries (fastboot.exe files)

save the wifi modules update.zip to sdcard (on phone)

reboot phone and enter recovery

flash the stock wifi modules update.zip

power down device

start device in fastboot mode

use the following command to flash the kernel.sin (or boot.img if u want to flash my older kernels)

fastboot flash boot kernel.sin

reboot phone and thats it u should now be on stock kernel (or my older kernel)

FOR OVERCLOCKING

start SetCPU/NoFrills CPU Control app on ur Play (or any other app which supports overclocking) (u may get a popup asking for SuperUser permissions, click ok/yes/allow)

now slowly increase the MAX slider to the right (one notch at a time) to increase the maximum frequency limit

DO NOT JUMP TO THE LAST POSSIBLE FREQUENCY

SLOWLY increase the frequency one notch at a time and do stability/testing for few hours

[ for modders/themers/others ]

hey guys here i am attaching a template update.zip which has been tested to work on the recovery provided here... u can add ur stuff to that file and edit the updater-script so that the u can flash ur files via this recovery...

basically it contains the correct combination of update-binary & mounting syntax...

this file is NOT required for normal/general users
