Requires Root: Yes     Apply In: CWM Recovery     Optional:      Optional:      Android Version:

This is my first kernel on the Galaxy Nexus. I came from working on two previous kernels on the Droid Incredible.

The kernel will only work on JB and is carrier independent as all Galaxy Nexus kernels are from 4.0.3 onwards. It uses the AnyKernel updater method so it's compatible with ANY ROM.

/* NON-STANDARD DISCLAIMER:
I understand that if I disable fsync I am liable for any possible data corruption that could result.  While dynamic fsync has been added, there is still the risk of data corruption.
*/

IMPORTANT: On 3.3.0/1.12.0 and higher, the WiFi drivers from the Linux 3.4 kernel branch breaks WEP functionality. Also, to ROM devs that want to bake in this kernel into their ROM, they will need to pull the hostapd file included into their /system/bin or WiFi tethering will not work.

*NOTE* starting with 4.0.1 there is now a Jellybean 4.1 version as well as a Jellybean 4.2 build with the old WiFi driver
Please pay attention to the zip you're downloading

I will give it a shot. I'm on Jelly belly 7.3. Which I really like the stock kernel; have had good battery life on it, and better reception(I didn't change any settings). Tried a few others, and leankernel seems to be doing just about as good as stock(I did use trickstermod app to change settings), interactivex has given me best battery life so far. And I will try yours out for a day. I'm mostly in Wi-Fi, I'm on the edge of Verizon network reach where I live so I get service just no bars. So that drains my battery pretty good. Sorry so long winded just saw no one posted. So thought I'd give your kernel a shot and report back for you.

Wow glad to see you here tiny. Your kernel rocked on the DINC.

Soooo I'm too clueless to know if this question is one of those "well duh of course it will / won't" but is your kernel compatible with TricksterMod?

[d00dr]

Awww yeah! Downloading and flashing the minute I get home from work! Tiny's kernels are the best!

[petecraig612]

Hey Tiny really good to see your work on the Nexus. You and chad had the best kernel back in the day for the Inc. I'm going to try this out, what kernel controlling app do you recommend using I've gotten FC's with Franco Updater and Trinity Kernel Toolbox.

[WhataSpaz]

Color control and trinity contrast? Flashing now

[parkson]

This is nice!

Awesome! Glad to see you working on the gnex now :) I'll definitely give this a shot later.

[runagt2]

Thanks for this man! Keep up the good work. Someone just returned my Dinc which I lost three months ago. Checked out the development threads and realized you and Pons are still making it kick ass!

I'm using trickster with it right now
