[Q] Which kernels for Nexus 7 3G

Hey guys, sorry I couldn't seem to find a similar question.
I have a Nexus 3G 4.2.1 stock rooted and would like to start trying out some kernels and Roms. I can see a sub-forum dedicated to Roms designed for the 3G version, however; there isn't one for 3G kernels. Does this mean all kernels are safe for the 3G Nexus?
And finally, which kernels allow setting a max frequency so I can under clock the nexus? Help greatly appreciated.

i dont know if all kernels work on the nexus 7 and nexus 7 3g, but i do know that trinity kernel works on all variants of the nexus 7.. wifi, 3g, 8gb, 16gb, and 32gb.

Thanks for the quick reply, Simms, I did read some good things about the trinity kernel and have been watching it for some time. Is underclocking possible with it?

yes. i run it underclocked every day(as my daily), at 1150mhz high/51mhz low. its also possible to disable tegra hotplug with it and use how many cores you want(1-4 cores).

Best Kernel for 4.2

Hey everyone, I have been on the hunt for the last few days for the best Kernel for my N7, in regards to performance. Earlier today someone turned me onto M-Kernel. I must say, it is very impressive. It has a built in 1.9 GHz overclock, that I was able to set via no-frills. I am running Clean ROM.
This is a multi-purpose post. First off, I wanted to let everyone know about my experience because I had a little trouble figuring out the best combo. The second reason is I would like to know if anyone knows of any other ROM/Kernel combos to get the highest quadrant score possible.
I have a co-worker who has a Galaxy SIII, and we have a friendly rivalry. I would really like to blow his phone away with my Nexus.
Thanks!

Check the link in my sig for my guide to the 'best' kernels. I don't think there is a lot of difference between roms in terms of benchmarks results.

Motley is an overall great kernel

Some questions about ktmanta and other stuffszz

Zup everybody.
Im a new android user and im loving it. With Nexus 10 to be my first android device im very happy with it after i installed ktmanta Kernel.
although i had very litte knowlidge about what roms and kernel is/was i went for it anyways. It improved my experience alot, and everything is running real nice. Also gta vice city doesent lag at all. it lagged like hell before the kernal install.
Now i have few questions and i hope someone out there could help me with. ive seen a few threads on this forum and everyone seems to be nice unlike other forums (no names mentioned)
When i flashed (i think its called that way) the ktmanta kernel i knew that everything would dissapear, but im wondering now if there is a way to backup exact everything before loading a new rom or kernel?
also. when i play gta vice city i use min/max 1500/1500 on the cpu and it works really nice. the only problem is that i have to manually change it and after i have played the game i have to go back and change it to 200/1700 again.
can i somehow make an ikon that i push and the cpu go to 1500/1500 and if i push another icon it will go on the other setting? something like that?
Ive seen folks wright on forums that there is an app that can make your battery life better but never mention such app.
i have batterycalibr, is that the only one?
And the last question is, is there something you could recommend to a new android user (apps,widgets, specific roms, etc) ?
Im loving the android experience and im considering to sell my iphone 5 and buy a droid phone.
(please i apologize if my grammar or spelling isn't at the top)

1. Try using titanium backup to backup your app data and you can restore it once you flash a new ROM/kernel. Remember, only backup app data, NOT system data or you may result in bootloops.
2. Not 100% sure if you could use the KTweaker app or SetCPU to set profiles when you're gaming but you might want to look into that. That being said, you shouldn't have to set your min at 1500 to have fluid gameplay, or at least I don't think so and it will drain your battery much faster. IMO, check out the franco kernel if you want to have the smoothest gameplay with no tweaking necessary and no drops in framerate.
3. I really don't believe in all of that battery calibrator, juice defender, or any other app that claims to significantly increase battery life. However, if you are going to use the KTManta kernel, you can undervolt your device and get some pretty awesome battery life.
4. What kind of apps, widgets, etc. are you looking for? Find out what your style is and customize accordingly. That's the awesome thing about Android!
Hope this helped... :good:

You have to flash the kernel with the app. It should be a very fast and easy process.

Thanks alot mate. I payed for the Franco kernel and then downloaded a file and had to restart my tablet. I guess i did the process right.
Now gta runs really nice without me putting min/max at the same mhz
Can i delete the ktweakert now ?

Yep! You won't be needing it anymore. I'm glad everything worked out for you!

Having your cake and eating it too

Most of life is a choice between one or the other but with the Nexus 7 along with Root, Custom Recovery, cm10.2 unofficial, Faux Clock Kernel Control App and Jassy Release 5 Kernel it might just be possible to have both. Jassy has managed to put together a kernel that combines a 1.9 GHz over clock and a 487 MHz GPU over clock. With a global undervolt of -24 MV I managed to pull off stunning benchmarks, smooth lag free performance and incredible battery time. Just under 13 hours battery time in fact. I did this with a YouTube kung fu movie fest for about 12 and a half hours and a half hour of benchmarks and downloading a few apps. Remember if you game you can not expect this kind of battery performance but it does do great at that as well. I've attached some screenshots of my settings so you can reproduce these results if you would like.
Remember when you Root, ROM and Over clock you do it at your own risk and please thank the fine Developers who gave their time to make this kind of fantasy possible. I in no way had a hand in developing this software, I just took the time to do many benches and battery tests on many Roms and kernels then undervolted a bit.

So to replicate your results, we need to flash cyagen, and jassy release 5, and then adjust the settings to replicate yours, or does jassy's release already have some of those settings in it?
What other apps did you download?
Getting longer battery life and a faster tablet is quite attractive!
EDIT I just installed jassy r5, and my quadrant is only 5679.. is something wrong, or do I need to also do the tweaks you listed here first?
EDIT 2: I've set faux to the same setting now, but am still using cleanroom1.3, and the quadrant results are 6787

Sorry I never saw your posts. Never looked at the thread again. To replicate my results you would have to download cm10.2 and Jassy release 5 and faux kernel control app paid version and set exactly like in the screen shots. I have since made a few more refinements but nothing you couldn't play with yourself. Make sure you enable mpdecision. Make every screen look like mine.

Fiops as I/o and 62c 82c as intellithermal is the only settings changed. Bout 7 hours of YouTube and 5 hours of heavy browsing. Couldn't ask for better battery life. NO Gaming.

Yep, I did duplicate them, but couldn't get quadrant scores anywhere near yours. (they were better though.. it might be a cleanroom issue).
I upgraded to Jassy rev 6, ran into issues, and then just reflashed the stock kernel.
I was hoping we'd see Jassy rev 6 lockup issues fixed, but its been a week now. I'm also read of a few misc cm issues, and I'e been waiting for them to clear up as well. Cleanrom isn't having any issues at all, so I've stuck with it for now.

Cleanrom will not bench as high. Its a stock based ROM. Truth is though once your this high your not gonna see a whole lot of improvement in daily performance unless you go looking for it. Cleanrom is one of the best Roms I've ever used and there is absolutely nothing wrong with sticking with it. I go back and forth between the 2 myself. As themes and tweaks come out for nexus 7 2013 you'll find cleanrom will get even better than it is now also. Wish someone would do a tablet ui lol.

I haven't had a single random reboot. Chrome works real well as long as you can change it from beta in lower left of xda page. I haven't overheated but I gotta tell you I'm no hardcore android gamer. Some angry birds from time to time or subway surfers lol. I have probably gamed for about an hour or so on these settings and not gone into a state of panic about temps though. Any longer than that or some other game and I couldn't say. in fact FOR me things are so smooth on this machine I had to order a new HP to tinker with lol. Seriously this is the best android machine I've owned. And buddy, I've had em all. I also use adaway so that may help with chrome as well.

Impressive scores man.
Yeah hesitant to jump to other roms myself at least at this time. Everything is so new finding a "good one" is hard to do at least yet. Though I've used CleanROM's on other devices I've had in the past and love them. Personally if CleanROM comes out with a 1.4 I might consider jumping into it.

Thanks for sharing! My only suggestion would be for you to recommend another kernel tuning app other than Faux's app. I'm just personally not a fan of someone who does nothing but kang, and even then still doesn't credit who he is kanging from. Too many hard working honest developers for me to support a faux developer (yes, pun intended. Maybe that's where the screen name came from?).
Just my $0.02.…

I have absolutely No interest in politics on my nexus 7 2013. if he did wrong, shame on him however I have tried each and every kernel control app on the market and reported my best results. I have yet to produce scores or battery life comparable even within 10% of fauxclock/Jassy R5 combo. I do not intend to do any research at all about whatever faux123 did or didn't do. I understand a personal grudge and respect your right to hold one. If your looking for something as close as you can get to his kernel control app try trickster. I didn't have a lot of success with it but you might find a combination that works close. If I were in the middle of whatever happened between faux123 and you or whoever I might have formulated an opinion. I'm not chiding you either. You brought an issue before me and I am simply stating I don't want involved as its in my humble opinion not my place or my fight, not to mention it appears it was already fought.
if I simply hated and didn't use a product based on someone else I don't know having a problem with that individual I wouldn't be able to buy anything, at all, anywhere, on earth, or in heaven, ever! If you tell me he harmed a baby and I see he was convicted of it in a trial of his peer's elected in a fair and balanced environment I will most certainly NOT have anything to do with him. But unproven or conflicting information, that may be due to personal interpretations is difficult for me to get involved in. Especially after the fact. And then there is the whole, if a man was punished for his crime do you continue to persecute him after he paid his dues thing.

Are there any deal breaking issues in CM? If not, switching does not bother me at all, and getting better all over performance is worth while.
I just don't want to spend more time tinkering with my tablet than actually using it.

What's your binning?

appreciate you sharing your jassy 5 set up with the fauxclock app. im on jassy 5 as well and have been running the setup that jassy posted but now im gonna try your set up. i just got one question about it: how is your sleep mode stand by time? i lose 1-2% in 8 hours

I personally would call the current cm build almost RC material. I have no problems with it at all.
My bin was 14/2 if I'm not mistaken.
I probably lose a bit less than that but can't say for certain as I constantly use it lmao. I do get exceptional screen on time really. There are some screen shots on previous page I think.

Cool. Might have to take the plunge. Do you have to wipe to install it? (I didn't have to wipe for cleanrom.)

The things we need
ROOT duh
ALL-F2FS FS support
NTFS FS support
CPU Governors
GPU Governors
GPU overclocking
CPU overclocking
RAM overclocking if we can
Dual boot ROM/Kernels and 64bit Ubuntu
any more ideas?

PIE control

Most important one.. Stability. Needs to be stable, and have a few minor tweaks, it all depends on how the stock kernel is though.. HTC Stock kernels tend to be pretty sweet anyway and just need a few features added IMO.

Have been told that the CPU is way under clocked @2.3,GHz and could handle 3.00ghz easy! Note that this is a rumour, but if true wow!
Really looking forward to it now!

Um everything you listed is stuff that is the norm for custom kernels. Wonder if well see Franco or faux or flar here...im still really on the fence.

At the price probably only if the device is donated. I'm sure the size is off putting for them.

USB-OTG and USB-Audio support would be stellar (if not included as standard)
:good:

I would love to see the GPU and CPU overclocking as well as over/under volt for both for maximum tuning capability. The other things I would like to see though are RAM and bus overclocking access since with so many GPU cores if we get to overclocking we may need some more in those areas too so we can take full advantage of the higher core MHz
