Kernel backup

[Cryceratops]

Hello there,

I'm running CM 10.1 currently and looking into flashing a new kernel (KT747) for better battery performance. I am still new to kernels but I was wondering how I would go about backing up the current kernel so that I can restore it if anything goes wrong, or if I am unhappy with the new one.

Thanks for the help.

Regards,
Mike

I just flashed stable cm 10.1.3 and am in the same position as you. Let me know if you find a kernel for us! I'm going to continue searching tonight.

This is the kernel I'm looking to flash, looks like a great one with lots of options for performance tweaks and battery saving:

Also, I found an app called Trickster MOD from the Play Store that allows you to backup your kernel... however I'm not sure if that's the correct way to go about doing this, I just want to be sure to have a backup of the CM kernel in case things go awry with this one.

So I went ahead and flashed with that kernel and everything seems to work so far. I haven't made any adjustments yet for battery optimization, but I'm working on it right now. I used this kernel from that thread: http://goo.gl/52odw

Goodluck, and let me know how it goes!

That's the one I've downloaded as well, still waiting on a reply as to how to safely backup. Let me know if you notice any improvements.

Hey man, if that kernel fails you there's another kernel called leankernel, which I actually prefer over kt747. I can usually overclock higher with better stability. Though, it's all up to how your phone handles it. Try making a complete backup of your rom if you can to save your kernel. Good luck.

Thanks for the suggestion, I'm still waiting to find out if there's actually a way to backup just the kernel without having to backup the entire ROM. If I should happen to want to go back to the CM kernel I don't want to have to restore the whole ROM, I can't seem to find an answer anywhere.

I'm kinda screwed right now. The file system on 4.2 is awful, and if you restore a previous rom and install 4.2 again it creates more of a mess. I'm in the process of fixing all of these directories currently. Just be careful.

Try to just reflash the rom, or flash a new nightly over it. That's usually what I do when I have a kernel I don't like, it flashes right over it back to the stock cm kernel.

The kernel is great, it's just the file system from 4.2 creating duplicates of my directories.
