Dude this kernel is awesome. Previously Franco was my goto kernel but flash was corrupted on it so I've been searching for something that ran as smooth but didn't have any luck till now. This kernel is SWEET. Paired with sgt7 it's a match made in heaven.
[Nexus 7 Android Development] Flukester69:
Yes very nice kernel! I too was Franco mostly but I find his N7 kernel is severely lacking and his app on N7 stinks compared to on Galaxy Nexus. While there is no immediate tools for this ROM, after installation I find no reason to tweak. Things seem very fast. I am using Dark PA 2.52 and its much better on this kernel.
[Nexus 7 Android Development] ÜBER™:
Lolwut? Its the SAME app. Just the nexus 7 is limited because of the LCD and limited tegra processor. I don't see what you're complaining about... and now on this kernel it has less but you're fine with that? :confused: making a ton of sense... :rolleyes:

I was having SOD problems on 0.3 (posted a last_kmsg).

Now on 0.4 I don't have any SOD, but instead when my device goes to idle and turns the wifi off, it won't come back online, and crashes the wifi settings menu when I try to go there to restart the wifi.

Eventually the switch in the main Settings.apk turned it off, and afterwards it's again working fine.

ROM related... I've experienced that with other kernels on the same ROM.

[Nexus 7 Android Development] :
How can it be Stock 4.1.2 related, though? :confused:

Also, if you've experienced it with other kernels on the same ROM, surely the kernel is the reason?

EDIT: Furthermore, Wi-Fi works great on the stock kernel, as well as franco.Kernel r25 (using the same stock ROM).
[Nexus 7 Android Development] Flukester69:
And by the way there is a lot of stuff missing in the N7 app. Is color profiling not possible on the N7? True the features are not there but then really the only thing the app does is load when you don't need it and allows slightly faster updates. There is a huge difference in the capabilities/usefulness of the app vs on the Galaxy so I don't get what your big huff is about. I own Galaxy and N7 n I use Franco religiously on my Galaxy. IMO the app is a waste to buy on the N7. This kernel however performs perfectly with no tinkering from the get go. Anyhow...
[Nexus 7 Android Development] ÜBER™:
So supporting the developer for his hours upon hours of work is not worth it unless it pack loaded with features... please. I was wondering why you were complaining about there not being enough in the app. Now you're using a kernel with no kernel app and very few options and you're perfectly fine with that? How does that make any sense. And i already told you its the nexus 7 fault not the app or developers. The LCD is not easily manipulated. So that is why there is no color control. The app doesn't just help you it helps support the dev, nobody said you need it everything is easily manipulated by a dozen other free apps. The point in buying it is showing support.

There was a reason why I didn't do interactiveX on this device... Man it's been so long I don't even remember lol. I'll probably do one or two updates until I put it on maintenance mode (ie. bug fixes only).
[Nexus 7 Android Development] 57op:
it works with cm12, but root is broken. i guess it's a ramdisk issue.

i'll try unpack original cm12 boot.img and replace zImage with your kernel.

If you're on Lollipop USB audio works out-of-the-box I tested this on my Nexus 7 running freakslim from here:

http://xdaforums.com/nexus-7/development/freak97-slimkat-t2897163

All OTG functions worked, USB audio, mounted USB stick only thing that didn't work for me was no charging in OTG mode.

On Lollipop all the USB audio and OTG-mode drivers are built-in. Just need a kernel that supports fast-charging in USB host mode, which does not exist yet for N7 on 5.0.2, if or when this comes out we should be able to run any 5.0.2 ROM in our in-car installs. We really only need the fast-charging enabling kernel now and can manage all power on and sleep options from tasker which is what I am doing now in my in-car install. My OTG cable is custom made though so the tablet can not provide power to the USB hub preventing USB devices from being capable of putting any drain on the tablet.

My install thread is here:

http://www.driveaccord.net/forums/showthread.php?t=286114

I went back to 4.4.4, but had to completely wipe the tablet from fastboot, load a factory 4.4.4 image from google from adb then load custom recovery, then flash custom 4.4.4 ROM, kernel and fastboot flash the chainfire root binary again to get back to autodroid with root.
[Nexus 7 Android Development] SkOrPn:
Freak released a new build today that is quite amazing in the way of smooth performance. The reason I am replying to your post is because in his changelog I noticed there were new Battery commits built in. I wonder if what you were looking for, fast charging, is now part of those commits? He is also using LK 5.2, so not sure about this. Anyway, thought I would mention it.

Oh and by the way, love the car install great job. My brother did the same thing to his Boxster S this week, except a permanent in-dash install, so I know first hand the fun you had, lol.

I am able to run stock 5.1.1 on LeanKernel. I wanted to get F2FS to work with /data and /cache but /data doesn't seem to work. The boot animation just kept going and the n7 never booted up.

Can someone confirms that deepsleep works on stock 4.2 wirh lean 0.6 ? Since i flashed the kernel deepsleep seems to have difficulry to kicks in.
[Nexus 7 Android Development] Imoseyon:
That's the plan for now. Plans can always change of course. :) All depends on how much time i can spare...

Jellybean's powerHAL will modify your max freq whenever it wants to. The stock powerHAL only knows to do that up to 1.3Ghz. Say you set the max freq to 1.5Ghz using setcpu, stock powerHAL will mostly likely reset the max freq to 1.3Ghz after the phone wakes from sleep. The modified 1.5ghz powerHal will reset it to 1.5Ghz instead. So basically flash the 1.5ghz version if you want to OC to 1.5ghz.

I will have another modified powerhal zip out in the near future that doesn't mess with your max freq at all.

Yup, confirmed. :)
