• 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 my kernel u will get "ERROR" while starting WIFI...
• i will be providing modules for my kernel which HAVE TO BE FLASHED VIA RECOVERY for wifi/bt (and other things) to work correctly
• stock modules will also be provided which again will have to be flashed via recovery if u want to return to stock kernel
  
  
  
  
• 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....

• stock GingerBread FW (.63/.67/.73/.75/.76)

1. download the kernel package update.zip (it contain the updated wifi modules)
2. save the package update.zip to sdcard (on phone)
3. reboot phone and enter recovery
4. flash the kernel package update.zip
5. reboot phone and enjoy the kernel

1. download the kernel.elf & wifi modules update.zip
2. save the kernel.elf in the folder with fastboot binaries (fastboot.exe files)
3. save the wifi modules update.zip to sdcard (on phone)
4. power down device
5. start device in fastboot mode
6. use the following command to flash the kernel.elf
   
   Code:

   fastboot flash boot kernel.elf

   OR
   
   
   Code:

   fastboot -i 0x0fce flash boot kernel.elf

7. reboot phone and enter recovery
8. flash the wifi modules update.zip for my kernel
9. reboot phone and enjoy the kernel

1. download the stock wifi modules update.zip
2. extract the kernel.sin file from the stock FTF u used to flash this fimware (use 7zip to open the FTF)
3. save the kernel.sin in the folder with fastboot binaries (fastboot.exe files)
4. save the wifi modules update.zip to sdcard (on phone)
5. reboot phone and enter recovery
6. flash the stock modules update.zip
7. power down device
8. start device in fastboot mode
9. use the following command to flash the kernel.sin
   
   Code:

   fastboot flash boot kernel.sin

   OR
   
   
   Code:

   fastboot -i 0x0fce flash boot kernel.sin

10. reboot phone and thats it u should now be on stock kernel

1. start SetCPU/NoFrills CPU Control app on ur phone (or any other app which supports overclocking) (u may get a popup asking for SuperUser permissions, click ok/yes/allow)
2. now slowly increase the MAX slider to the right (one notch at a time) to increase the maximum frequency limit
3. DO NOT JUMP TO THE LAST POSSIBLE FREQUENCY
4. SLOWLY increase the frequency one notch at a time and do stability/testing for few hours

1. for better battery life try undervolting... start off in steps of -25mV and see which is stable for u... for my phone -100mV was stable...
   
   
2. before u report any battery drain issues please read this:
   [GUIDE] HOW-TO Properly Evaluate Battery Life and Provide Useful Reports
   
   
3. faux123 has posted very nice info regarding most features

if u feel that this work has helped u OR u think that the work i put into making this is worthy of donations, then click on the following link for buying me some coffee/beer/etc

If you like to use my kernels and u want to show the world that u use it/love it , then you can add this banner to you signature!!!

Ok so a weeks testing unless stated otherwise below is what i'd consider heavy use.

1080p youtube videos in browser and youtube app for at least an hr, stability test app for an hr, emu games, phone calls etc with 384/1.5ghz(I won't OC any higher then this sorry)/ondemand/deadline and dalvik cache wiped after flashing.

9002 - Used for 2 days, no issues found with the above tests, 41deg max and Stable.
9003 - Stability test report shows ~6mins @ 36 degrees it rebooted. Unstable.
9004 - Used for over 3 hrs with ondemand/BFQ IO set, no issues found with the above tests, 40 deg stable.
9005 - Used for over 3 hrs, no issues found with the above tests, 40 deg stable.
9006 - Used for over 3 hrs, no issues found with the above tests, 40 deg stable.
9007 - Used for over 3 hrs, no issues found with the above tests, 41 deg stable.
9008 - Spin off for 9003, stability test report shows ~1min @38deg it rebooted. Unstable.
9009 - Used for 2 days, no issues found with the above tests. 41 deg stable.

I was able to break the phone with 9003 and 9008 easily with out even overclocking and I always ran stability test first.

No bootloops experienced.

Doomlord can you make a kernel with all the above commits with out these two (9003) offenders for testing? I'm back to using 9002 happily so i don't believe the gpu overclock is having an effect on stability, definitely not for me.

Free Stability Test app in market if any1 wants to try:

Stability test log after 9008 crash attached.

After a while of testing with 9002 vs v1a vs 9009, 9009 offer the best stability without producing unnecessary heat and worse battery life. To me, GPU oc is really not a good option compares to performance vs battery life in return. Perhaps you can release a kernel with all the above optimization without oc of cpu and gpu?
