trinity kernel works fine too

I'm loving the trinity kernel myself! It is blazing fast at 1.7Ghz. (gets a little warm but other than that it is just awesome) No issues so far using stock 4.2.1 ROM

Stock ROM, as in not rooted? If you are running a custom 'stock' ROM, as in you flashed it to your device than any number of good kernels will do what you want.
But at a minimum you need to be rooted and have a custom recovery installed.

S-Off G2 Flashed with pre-rooted 2.3 ROM, now can't overclock :(

I just flashed my G2 with this ROM:
http://forum.xda-developers.com/showthread.php?t=1211143
I'm rooted S-Off, and I just came from bone stock factory 2.2.
I overclocked my phone using this method:
http://forum.xda-developers.com/showthread.php?t=813681
And all worked fine until I flashed the 2.3 ROM.
I adb pushed both .ko files to test them out, and I keep getting this error in my terminal emulator: "insmod: init_module '/data/local/vision_oc.ko' failed (Exec format error)" I'm running the command as su, obviously. I don't see why flashing a new ROM would effect my ability to overclock without replacing the stock kernels...
You're trying to put a kernel on there made for the 2.2 ROM.
You're running a 2.3 ROM. Right now there are no custom kernels to overclock that ROM that don't also break other things on the phone.
If you want 2.3.4+ and overclocking, look into one of the other custom ROMs made from AOSP (like CM7) that come with custom overclockable kernels from the start, or have overclockable kernels available for them.
So is CM7 stable for the G2? Meaning that everything works (WiFi, GPS, video playback, etc.)?
Because right now this bone stock 2.3 ROM I'm running is seamless, I'm not really a tinkerer, I just want things to work.

CM7 is extremely stable. Its been in a stable state for a long long long time. And has more features than stock with better performance and battery use. I flash nightlies and its more stable than some ROMs out there.
Just make a nandroid backup of your current ROM. You can always go back...
What about g-lite?

+1 for glite. Pretty much stock with an Oc daemon. I love the awesome battery life as well

yea I've been meaning to try it got the stock prerooted now, just have to get tired of it lol.
you can use setcpu and set 8X55 can use 1ghz
You can also use cm7 with the stock kernel and OC your phone to 1ghz easily.
Cm7 is very stable btw - ive found nothing which is not working.

Question about the custom kernels

Hello all,
I was wondering why arc's developers are only working on custom roms which require custom kernels... I am not a rom developer, I am only java developer with knowledges about the android development system. That's why I wanted to tell you this question. We have GB roms based on stock 2.3.4 which run very well with stock kernel. Like aniking or TEAM rom. Is it about the lack of recovery in the stock kernel? Or the lack of performance in the ICS stock kernel? I can't unlock my bootloader (Carrier branded) and I don't want to unlock it by tespoint for now.
Thank you for your replies
About the possible mistakes, I'm French, sorry for that.

I've experienced the stock kernel as heavy on the battery. Replacing it with CWM stock kernel or other increases the battery time, atleast that's why I rather stick to the custom roms and kernels.
Customs kernels have more battery drain than stock so prefer them if you are heavy user I think you confused..the customs have other benefits.

I agree, custom kernels have bigger battery drain than stock in most of the cases. But that's not my question : Why there's no ICS roms that run on stock ics kernel? I know the benefits of custom kernels, I used them with my previous X8. But for now, I can't unlock my bootloader.

i been using doomkernel and haven't seen a significant battery drain in compared with stock. or maybe the difference is just not far apart. used custom kernel just so i could oc that slow 1ghz

Any ICS ROM based on stock firmware will run on stock kernel. Arconium ICS works fine on a stock kernel. However we need the recovery to flash zip files and make backups.

[Q] Custom Rom or Stock?

So I've had my Nexus 7 for awhile now and wanted to getting everyones opinion on how they run their Nexus. What rom do you run if you run one or why do you choose to run it stock? I am currently running a simple TabletUI.zip. Give me you thoughts and opinions.
In still running it in stock because it's good enough for me atm x). I don't need tablet ui or something else. Opened bootloader and rooted.

I am very much into custom roms for my Sprint G'Nex but for the Nexus 7 I run stock. I do have it unlocked and rooted just in case but as of right now, for what I use it for, stock JB is great.
i started with rooting and tried the franco kernel.
Someday i just tried a custom rom. Not for any reason, just trying and playing around a little bit.
Thats mainly it.
I do it, because i can
Stock is good, but Paranoid Android is REALLY good, and the tweaks it has are probably much better than the TabletUI.zip. I just saw a ROM called "Cookies and Cream" that is based off of Paranoid Android and Codename Android, so that one's probably worth checking out too.

[Q] new nexus 4 user, kernel recommendations?

I'm no expert in advising you but I personally use semaphore kernel and I really love it! Franco is the best for saving up juice in your phone! And if your a extreme overclock fan then faux must be your choice! For gaming matrix kernel or ma1rix kernel is the real deal. Note i guess they are still working on 4.3 bootloaders so just check their threads out and confirm that it is for 4.3 bl or not.

Nexus 7 3G 2012 doubt

Hello all,
I'm on the forum for a long time, now, in the beginning in the HTC Desire forum, then on the HTC Sensation and now here.
I just bought from a friend an used Nexus 7 3G (Tilapia) tablet, which I really like.
I realized too late that the 3G model has far less developmnent activity with regards the Wifi only model, probably due to its far less distribution.
Now, I rooted my tablet and installed CM11, but I'm not completely satisfied.
What I'd like to have is a Kernel with the possibility to overclock the tablet, but I can't find any for the Tilapia.
Moreover, the available ROMs are not too much, and all based on CM11.
So, my questions:
1. Is there a stable Kernel I can use with CM11 (Kitkat 4.4.2) with which I can overclock the tablet?
2. What would happen if I install a Kernel + ROM designed for the Grouper model on my Tilapia? Would it work (with the exception of 3G, of course)?
In other words, is the hardware the same on Grouper and Tilapia, so I can use the saem ROMs and/or Kernels?
Thank you in advance.
Ciao,
Giovanni

V1.4 is what your looking for. Unsure if it will work on the tilapia though, if you wanna try it make a backup prior. If you bootloop/hang at boot hold vol down and power that will get you back to bootloader where you can access recovery

How did that work out for you?

Hello,
At the end I installed SlimKAT ROM, which is very slim (pune intended) and fast, together with the Faux Kernel.
I'm running the "Ultimate" version of the Kernel, running the processor to 1.7 Ghz (actually, 1.6Ghz): I cound't be happier!
Ciao,
Giovanni
