CM7 Kernel Recommendations?

Hello all!
Just upgraded my wife from the MyTouch 3G Slide to the G2 as she has to have a keyboard and we were on our 5th replacement Slide. So, as she is not the geek that I am, she will not be constantly flashing new ROMs and such. However, I am going to at least install the latest CM and I am looking for kernel suggestions. I already have root, s-off, new hboot, and all that, I'm just waiting for CM7 to finish downloading.
I started using Android with the G1 and constantly updating Radios, as well as ROMs and I currently use a Samsung Vibrant running a TeamWhiskey ROM. It's stable as anything, I like the theme, and CM7 still has some broken stuff on the Vibrant. I'm glad to see that Eugene recently picked up a G2 as he made some bad ass kernels and ROMs for the Vibrant.
So, let's here those kernel recommendations and why you recommend them.
Thanks!

Well am currently using mexdroidmod and their kernel is pretty awesome because its fast and stable. My best advice is to test the diffrent kernel and read through the tread, see what people say about it. All the kernels I have tried are all awesome so you should try them

pershoot's kernel. great batt life and OCing

Umaro's kernel has been rock solid for me and has tons of features as well. You can OC all the way to 1.9 Ghz if you so please and it has smartass.

well considering your wife isn't much of a techie.. i say you should go with pershoots kernel because he's always releasing updates and i've never had a problem with any of them. the battery life is excellent if you use the right radio (.17 and .30 have been good to me), but you need to experiment with this though. the phone runs beautifully, just make sure you use superwipe+ to format/wipe so you don't end up with gps issues like many people have had, good luck!

I've run umaro, eugene, pershoot, flippy, pyro, etc etc... aaand I've decided that the provided kernel is pretty much good to go. yeah, there are some little trinkety things with a few of the above kernels that the standard CM7 kernel doesn't support... but honestly, they're worthless to a user who just wants to turn the phone on and have it work.
set her up with the stock kernel @ 245-1017 (I haven't found a reason yet to ditch the ondemand governor, it seems to work best with CM7) and a vanilla gingerbread launcher and she'll be blown away.. that's my $.02

Like said above, CM kernel is great. I've tried most or even all available kernels for CM and finaly decided to stick with original one. It's stable and supports OC (up to 1.5GHz) "out of box", so really, I see no single reason to use the other ones.

I'm also thinking about changing the kernal, but only for smartass. Does smartass offer that much of an increase on battery life or anything else? Also, when you OC, do you use SetCPU or just CyanogenMod Settings?

not at all pooping on any of the guys who swear by smartass/other governors, but the change in battery life is almost unnoticable for me.. the change in performance however can be pretty apparent.
here's my problem with "battery saving" governors:
in order to save battery, these governors are supposed to be more intelligent about which frequencies they select once a task is called... well, that's all well and dandy, but the problem is that the majority of battery-hogging apps (ie streaming music/video, gaming, browsing for a long time, being on the phone, etc) are still going to be battery hogs with or without a fancy governor. the governor isn't capable of making an app that needs a lot of processing power run well at a lower frequency, it can only try to be more selective about which frequencies it uses in order to attempt to save battery life.
additionally, most people use their phones like this: phone is idle (ie screen off), and a call arrives. call ends, phone is back to idle. texting a few people, back to idle. playing a game for 15 minutes, back to idle.
is it really logical to assume that these short bursts of activity are going to benefit at all from a fancy shmancy governor? I doubt it.
I still swear by ondemand or interactive (both work well for me) thru built-in settings if possible (ie cyanogen performance settings). second choice would be setcpu with no profiles (unless you're overclocking heavily, then you should at least have a temp warning profile). at this point, screen-off profiles don't do a damn bit of good, because pretty much every kernel we have for the vision is going to scale down during inactivity.

[Q] Trinity V.S. KTManta for AOKP Pub? (N10)

There seems to be two major kernels that people use with the AOKP Pub ROM. Which side are you on and please do share with us why? Thanks

I don't use AOKP, but I'd use Trinity. It's familiar to me since I used it a bit on my Nexus 7 back in the day, has a fsync toggle, and I find KTManta has... a lot of settings (this really isn't a problem though for most people)

And its about to get a LOT more

Many people actually site the abundance of settings as KTManta's strongest feature. Case in point would be the fact that it seems to be the only kernel out there that has any sort of display calibration settings, although still considerably lacking. So from a performance standpoint the Trinity has an edge then?

They are both great kernels... We are lucky... You can't go wrong with either

Yes and no. At stock settings between both I think Trinity does have an advantage, because Im pretty sure 620MHz is the default speed for the GPU. KTManta is faster right now, but it also allows for higher clock speeds and has more options. But those higher speeds are not default on the KTManta kernel, you have to select them if you want to overclocked GPU on your tablet.
Both kernels have automatic RAM overclocks up to 866 MHz when you get to the higher GPU steps (above 533 speed), but KTManta will have in its next release (unless Ktoonsez and my tests say otherwise) up to 912MHz memory speed. But again, that wont be default as it is a high overclock setting. SO default to default, Trinity, but when fully tweaked out on both, KTManta is faster. There are some nice and easy settings pre-made to load in the tweaking app if you dont want to do the fully tweaked out settings yourself. Some really great member posted them on page 275 of the KTManta thread :silly:

i use ktmanta 03-02-13b with aokp
positive
- stability ( except inserting a device through otg )
- fast
- battery ok ( ktkoonservative , sio )
negatives
- gets too hot in games
- zen not working for me ( letters corruption)
- not compatible with pppoewidget drivers for my modem
Trinity kernel are very good for battery and coolness , except i can use them with my external hdd
New ktmanta are the best now for many ,i think, but for me gives instability problems ( restart when use the bar progress in a movie with mx player , restarts sometimes with the default settings )
Franco kernels are still imature for me .
They all are very good kernels from very inteligent developers so we are in good hands for this device . you should try it all . as many here saying - every device reacts different.

You mentioned that your device becomes too hot in games. Is that under stock or have you done modifications such as with the clocks, voltages, etc.? Thanks

[Opinion] WHICH SETUP WORKS FOR YOU?: Best Rom/Kernel/MOD configurations

The purpose of this thread is to have the HTC One community come together and share what configurations work for them mainly when it comes to Battery Life and Performance.
Now after being a SENSE Lover for so long, I was hesitant to leave it mainly because of GPE/AOSP crappy Emoji's. Then after forcing myself to move to AOSP, I found it hard to leave because of HALO. Then upon finding out that HALO had been ported to the Xposed Framework and finding a way to put apple emoji on the HTC One, I decided to try out a GPE Rom which led me to create this thread. Here is my current configuration:
ROM: SinLessROM GPe v6.2.5 Beta 4.4.2 (with Nocturnal Settings)
[ http://forum.xda-developers.com/showthread.php?t=2348176 ]
Kernel: ElementalX 11.4
[ http://forum.xda-developers.com/showthread.php?t=2249774 ]
CPU underclocked to 1350 MHz
Undervolted to 725 Min
GPU Overclocked to 504 MHz
GPU Governor: Simple
CPU Thermal throttling: Run Hot
Manages CPU Cores: Battery Savings (Experimental)
Logo2Menu
USB Fastcharge
Enable Graphics Boost
Enable extFAT support
Went to Developers Options and selected "Force GPU Rendering"
Runtime: Dalvik
Performance: This configuration has doubt been the BEST I have ever used. The phone is extremely snappy and the problem I used to have that my phone wouldn't charge while it was plugged and I was using it is completely gone. My phone NEVER gets hot or lags, even when watching movies while being on a phone call (don't ask lol) or listening to music while playing Real Racing or Asphalt 8. There's was no need to overclock the CPU so instead I Underclocked it to reduce heat. I used to be the type to Max out everything but I've realized that in reality, how much power can an app actually consume? Apps open in a second and I have absolutely NO hiccups in any of my apps.
Battery Life: As you could see from the screenshots over provided, I've never had battery life life this before. 6 hours plus with the screen being on about 85% of the time and phone being awake about 90% of that time (I'm a heavy user) and still being on 29% left is simply amazing (to me). Not to mention one been listening to music (Apollo Music Player) about 75 of the entire time.

How did you get the good emojis on Sinless ROM? I want the Sense or AOSP ones, not the stupid Google Hangouts ones.
I dislike the Hangouts messaging app as it has bad looking emoji icons and no "return" key to make a new line when sending text messages.

[Q] Best Working Set-ups

So for the newbies (I have been modding Androids for a years now):
What's the set-up you have found to work best? Are there any issues with it?
Here's mine:
Cyanogen 10 (ROM)
KTManta with kttweaker app(kernel)
interactive CPU: 2100/200 GPU:720/100 (Governor)
FIOPs(scheduler)
Notes:I also gave a five volt boost to the CPU steps (but I would do this last thing and only if you need it). Advice from Omnislyfer: I would like to tell you is about the overheat of you device. Our exynos processor it's great, but it has got some problems with temp at higher frequencies. You have overclocked a lot your device, and I think it's an insane thing to do. The main goal of voltage settings are to undervolt the device at stock frequencies, in order to reduce the overheating effects. You have done exactly the opposite: you have OC your device and also you have rises the voltages. So thrust me: from Ktweaker app, load default settings (so max CPU free will be 1700, and 533 for gpu), then subtract at least -50mv to all CPU voltages and -25 gpu voltages. You will not see particular performance loss (our n10 rly doesn't need Overclock) and hoverheat problems will disappear. Thanks Omni, I currently am testing this. Edit: Tested and this is great advice for this kernel. There is still heat issues for cpu intensive apps, but they are slower to manifest. Straight GPU functions (MX player -HW+) do not seem to need the undervolting and may be able to be ramped up. I did not test with any intensive games as it is hard to seperate the processors.
Video player (this is important for Nexus 10's):
MX Player with the custom codec properly installed (it occasionally (1/100 hours) drops the app when streaming video (twitch), but re-opens easily.
Comments to the community: I agree that people should try out everything. However, I recently had to re-root an old phone and run back through a lot of threads to find a stable set-up. This was to even see if I had rooted correctly. On the Nexus 10, the base Cyanogen 10 kernel kind of blows and my device was all sorts of buggy. The purpose of this is to help new modders and share some knowledge about stable set-ups with each other.

I've ran the gambit of custom ROMs through various versions of Android swearing by one over another but in the end I returned to rooted stock, Franco kernel, XPosed framework with Gravity box. Stability is my driving force and that just seems the most stable without loosing features such as the immersion UI.
Must have apps:
SuperSU
Viper4android
LMT
Nova launcher
Neutron
MX Player
For me other apps fall off in importance but those are the ones I'm taking to a deserted Island.
Sent from my Nexus 10 using XDA Premium HD app

And this is my config:
-Purity ROM - - > clean, stable and fast;
-Trinity Kernel - - > extreamly fast, but it leaks some feature (there is No Undervolt);
-ART runtime! - - > you have no idea of the advantages. Everything is faster and great battery life improvements.
About the apps :
-SuperSu;
-Nova launcher;
-Trinity Kernel Toolbox;
-MusicFX

Hi,
First I think you should give a look at this thread: http://forum.xda-developers.com/showthread.php?t=2725128. Many people are sharing their configurations there, it may help you .
For me, I'm using CM11, no additional tweaks for kernel or anything else, just CM11 was good enough for me. I can play Dead Trigger 2 without frame drops, listen to FLAC audio in Poweramp without issues and watch heavy videos on MX Player.
Also boot time is ≈20 seconds, so I found this to be my favorite setup .

[Q] The best ROM for gaming

Hi guys,
first of all let me apologize for this stupid question. Personally I hate these questions too, but I have my device in service for 3 weeks, therefore I'm not able to continue with my research...
It's already a long time since I've bought my G2 (D802). Of course, the first thing what I've done > go to custom ROM ... (It's my habit since Xperia Arc S) I think that I was dissappointed of my new LG G2 even then. Games wasn't fluent and lagless as I supposed they should be. It was another good reason to go to the custom ROM. But unfortunatelly and surprisingly it was even worse. So I find another thing why is that so bad. In that time custom ROMS wasnť based on Kitkat sources (kernel), so I hoped that everything will be fine after developers merge source code. But the improvement has never become (in that form I hoped for) In that time I became reconciled that I will never play games on my G2 as smooth as on my iPad.
That's the reason why I'm looking for the best ROM for games. (I'm a heavy gamer)
So my question: Do you know any good rom for Gaming? Could you recommend me something?
I tried Mahdi. PA, Beanstalk, Slim ROM, CloudyStock, Pro, Flex, G3... But none of these ROMs is fine...
(I can't understand how can be Cloudy ROMs so popular (Nothing against Cloudyfa ) because they have too many lags in games !!! I think it's more laggier than stock...

What's the definition of "lagless" for you, and what games are you playing?
First of all, you have to realise and acknowledge that this is a smartphone. No matter what, it's still a phone and it's not made for heavy gaming. Second, you have to realise that despite the fact that many developers (ie Gameloft) has a lot of experience with games, they're too lazy too optimize them even for the most powerful chips out there. The games utilise 100% CPU speed even if they don't need it at all, and then the CPU throttles down because it's becoming too hot. Logic/10.
Thirdly, you have to realise that the ROM is not what makes the game fluid or lag-free. It's the kernel.
Since the G2 (like ALL other phones) is cooled passively (it has no fan whatsoever), it's important that it runs as cool as possible to prevent overheating and throttling.
My advice to you would be the following:
Install your favourite ROM and a kernel you can tweak heavily (gpu/cpu). A good bet would be dorimanx.
Go to kernel settings, and chance max frequency to 1.27 Ghz or around that. Change governor to performance.
Change GPU to 450 Mhz.
Try playing a game =)
I used to play Asphalt 8 back when I first got the phone and I got about 30 FPS? Anyway it was smooth as butter, and I see no real reason why you want to put a custom rom on your phone. The good 'ol days where nothing was better than custom roms are pretty much over. Stock is just fine, root it, use a custom kernel if neccessary and use xposed. Will solve it.

Of course that kernel is the most important thing in performance (because of sequencer laws, etc...), but nowadays we have no (except render) custom kernels for AOSP/ CM ROMs, so my question was focused on a ROM → I connected it to the whole... (And furthermore each ROM has own kernel. + ROM can cause lags as well)

Unfortunately these times are gone, at least I think it. There were lots of updates, which increase the performance consumption (Simply they add tons of new features and stuff, but they ,,forget" to optimize that... ) I played this game, Dead trigger 2, Dungeon Hunter 4 and even simple games like traffic racer with incredibly high count of lags (And it wasn't lags in miliseconds → not always). I thought it was because of my current ROM (Mahdi) so I tried PA and then stock based ROMs (CloudyFlex, Stock) but nearly no changes) Therefore I think it will be the same on stock ROMs too, if it's on Cloudy ROM with heavily optimized kernel, system... (Even Dorimanx kernel doesn't change anything).

Thanks for this tip, I tried something similar but with UC to 1,9 GHz and I didn't set governor to performance (My device was incredibly hot in a while with performance governor), I didn't notice any bigger changes - I expected that lower frequency will cause even more lags and I was obviously wrong. For sure I will try your advice.... :laugh:

I don't like the LG's design of system, and I don't like xposed → it causes higher battery consumption and it ,,eats" RAM and performance (At least on my previous device )

i have 10 xposed modules installed and i didn't notice any additional battery decrease...
as for ram, as stated many times - free ram = wasted ram...
as for the thread - "what's the best this&that" threads aren't allowed on xda
i played rr3 and csr racing on this device and didn't notice anything wrong with the framerate (stock kk v20f, rooted with dorimanx kernel on default)

Oddly enough, I haven't noticed a major change in gaming performance coming from the S4 Pro. Asphalt 8 specifically is buggy, sluggish, etc on my LG OG & G2, but I don't care for android gaming since the apps aren't optimized (too many HW configs, whereas iOS is just SGX & Ax chips).
Transmitted via Geass

First of all, I like to say that we lacked similar threads, so OP started an useful topic. I would have stayed with simple dual-core smartphone, but I bought G2 in November for a reason, to try new games and so on, I woudn't have bought it if I needed a phone only for texting and browsing, like many argue like this. What I observed is that, 2,3 Ghz for a phone with passive cooling is a nonsense because after few minutes of gaming it will keep running like 1,5 Ghz and lower, hell what's the use of those 4 cores if a device would burn out. I never owned an apple product, but on my colleague's 5S, they run very smooth and fast with same graphics on a dual-core, so it all goes to optimazing and not using these ridiculous frequencies. I was expecting a lot from a phone like that, sorry for a long post.
