[KERNEL][CM11/4.4.2] [ACCLAIM]»»Bexus-N2»»R5.1!!!

Demetris · Feb 19, 2014

As a side note i want to thank you guys for the love you show on my work here.
This kernel is focus on making your NookTablet awesome without sacrifice on speed vs battery life.
Hard task if you ask me.
Till this moment nothing is used from the V1 kernel this is a brand new kernel from the updated chrmhoffmann cyanogenmod cm11 branch.
Am going though to merge some commits i find appropriate to be in v2 as time goes by, but wont see much updates as i was working on this some days now and is already on a solid state.
So with no further delay enjoy for the last time my hard work

And the usual this stays mine thread

As always, thank you for your hard work Demetris. The ~$200 I spent on this would have essentially gone to waste because I didn't realize how awful it is by itself. This was my first Android device and your kernels and roms have helped me realize how powerful and fun the Android OS really is. I only buy Android now and it's because of how awesome you've made this tablet. Thanks again for your work!

On a side note, and not trying to be all gushy, but you've indirectly inspired me learn programming so I can do stuff like this! So thanks again man!

as opposed to cm11 bexus-N why is there no overclock on N2? as well as other features. installed it and its like it was never installed. like its still cm kernal. no changes at all when i install this one. will stick with cm11 bexus-N1. but still ty so very much demetris. a statue should be made to commemorate your awesomeness.

This link will explain all

Instead of rebuild V1 i just build a new kernel based on the newly updated cm-11.
Some things will be merged but 1.2hgz is as much as we can go on this kernel.
I need this kernel to be somehow battery friendly so i will balanced everything that comes in it for that purpose.
And p.s
This is not Bexus-N but N2 kernel i just liked and kept the name

What's the current max CPU frequency of this kernel? 1GHz or 1.2 GHz?

For now is 1ghz but am considering the unlock of the 1.2ghz as i think is the default freq for this chip and not an overclock.

OMAP 4430 is rated at 1 GHz by TI themselves....

http://www.ti.com/product/omap4430

...yet in applications like Samsung Galaxy i9100G, Motorola Atrix 2 and many others it runs at 1.2GHz as delivered by those manufacturers.

Bexus-N2.2 out.
Nook Tablet is now 100% bug free.
If we don’t get emulated sd cards, i have to revert the external as default i want and need the internal one to be the default one. Any different opinion please feel free to express it.

newbtrigger69 · Feb 25, 2014

soopah smooth. A+++++ better compatibility with certain apps and relatively smoother than cm 11 bexus-n1, and n2. :good::good::good::good:

Chunky Monkey · Feb 26, 2014

Highest benchmark on cm11 for me by far. I even saw it tick up to 16.2 fps during graphics test in AnTuTu.

@Demetris, firstly thanks for your work.
Your BexusNv1 is excellent, videos and everything work, and programs run super fast thanks to higher clocks.

Is it possible to clock this kernel to 1.3GHz like in BexusNv1? via commandline maybe?
Also, does this kernel support mapping the internal SD as the external SD and vice versa? 12GB is going to waste in my NT because programs complain about it not having an external SD card (I partitioned my data partition to 1GB and media to 12GB).

I'm with you.

I'd be perfectly happy with Internal storage as SDcard0, as it was configured in the original nightlies.

You wont need 1.3ghz on next release

Saw a 16.5 fps. Awesome.

Thanks a lot

newbtrigger69 · Mar 1, 2014

Thanks so much for this kernel. Getting around 10500-11000 on Antutu. BexusN v1 got me to only around 9000.
One problem, YouTube keeps playing in the background once I close the browser. This didn't happen in BexusNv1.
