Stock O/C Kernel 1.7Ghz and CM/MIUI/GB O/C Kernel 1.8Ghz UPDATED 01/09 - Grankin01

---

First is an O/C kernel that I built from the HTC source. This kernel is stable and with the right profiles setup in setCPU has given me very good battery life. I'm giving coolbho3000 credit here as his post in the G2 forums is what helped me to do this. I am also acknowledging gr8gorilla who helped me several times through this process. Second is a kernel built from the latest CM kernel zource from zinx. It has proven to be very stable (after tweaking the voltages).

Now for the boring part ... If you choose to flash this you do it at your own risk. I am in no way, shape, or form responsible if you flash this and your phone turns into a paperweight. Once again, flash this at your own risk.

There, now that that is out of the way we can get on to the good stuff.

Make sure you choose the right kernel. The stock kernel will break your CM install if you flash it.

CM7-Gingerbread Kernels
Do not use these with CM6-Froyo! They have different ramdisks and wifi options built in.

These kernels have no issue with video. If you are having trouble with youtube and such update your GB rom to one of the newest. There was a memory leak in the source for the rom itself that zinx has fixed. Thirty to Forty-Five minutes of straight youtube action and I had no problem at all.

I have packaged this into an update.zip format that you can flash through your custom recovery. Simply choose to install a zip from the sdcard and pick the update package to install it. It will install the wifi driver at the same time so you don't need to worry about that. Everything works with this kernel so far for me if you have any problems please post them and I'll see what I can do to fix them.

Remember that you hardware is not the same as your neighbor's so while he may be able to max the settings out and run stable your device may need to be set to a lower clock speed to run stable.

Source code for both kernels has been added to github. If you want to play around with them download source from here: https://github.com/grankin01

Happy Modding/Devving!

wow, thank you sir

I was just about to start testing kernels with Zinx's CM6 anyway. Looks like yours is first.


hmmm... could not run update.zip through clockworkmod. I was looking to extract the files and push them manually, however, I don't see a zImage file to push.

No luck with the miui rom. Cant get past the splash screen.

Yeah, its based off of CM. I'm working on one built fromthe CM source right now.

There isn't a zimage. I wrapped it all up in its own boot.img and then packaged it in the update.zip with the wifi module.

Does this break the nightly CM ROM? I know gorilla's kernel does.
I appreciate your work!

Yes, it breaks it horribly. I'm working on it now.

Thanks for this grankin01. Great work to you and the others involved.

So no miui or cm6 on this kernel correct I just dont wanna break anything.
