Kernel issues - General Questions and Answers

Hey guys, I've just flashed my evo 3d with Yoda's rom. It runs pretty good, only that when I installed the rom it asked me if I want to install Yoda's custom kernel. And I did, but here comes the problem! When I had Yoda's kernel installed it wouldn't let me toggle wifi on. I tried reinstalling everything, flashing the rom and kernel separately, but no luck. Soon I figured out that it worked only with the stock kernel.
--------------------------------------- -Is there any other kernel that could run with Yoda's rom? Sorry for the long post. I'm new to flashing kernels and I couldn't find any answer.

Cm7 and faux 0.1.2

Just curious... I have revolution hd 3.1.0 with faux 0.1.2, but its randomly restarting for me. Is this because of the ROM? And if it is, and if I flash with cm7 rom do I have to remove faux kernel 0.1.2?

When you flash CM7 it should replace the faux kernel with the CM7 kernel. CM recommends sticking with their kernel for the CM7 rom as well.
Thanks, the cm7 thread is developing and someone just pointed it out.
Exciting day... I hope cm7 will kick butt..

Which version of 0.1.2? If you opted for the higher clock speed version, your phone may just not be able to handle it.
If you flash CM7, it will replace the faux kernel with CM7's.
But if you flash CM7 I would recommend Faux's kernel for that as well. It's smokin' fast! I didn't have any shutdowns on the 1.78GHz, but I still went back down to the middle speed (1.67GHz iirc) just to prevent a lockup when the system is really stressed. Who knows, CM might have a better kernel than Faux after it's all said and done, but it's fun to play with as it all develops

[q] my screen is black afer installling kernel!!

I just installed the [Kernel]CM7 [2.6.32.45] on my phone with CM7 already installed. when I turned on the device after the LG logo my screen turns black?!! What coulfd be the issue...I apologize if i come off as a idiot....
You installed what kernel???
From who?
From where?
Cm7 rom has a stock kernel, so you must have flashed a custom kernel, did you check to see if it was compatible with cm7??
Yes its this kernel [Kernel]CM7 [2.6.32.45]. I downloaded from XDA and it says its compatible with CM7. When i rebooted the G2x from CWM the LG logo showed up and then went to a black screen
Just enable USB connection and put a different kernel on ur phone and flash it. Ur phone obviously can't handle the kernel

Which CM7 Kernels could the G2x handle fo.....Im new to the whole kernel thing & im tryna get some help & I want to get more power from my phone.
Each kernel is different for speed, battery life, experimental... so on and so on. Every chipset is different in our phones some can't handle certain kernels.
Sent from my LG-P999 using XDA Premium App
So what kernels would work on any G2x?? Thanks for the tip idk all our chip sets are different.

Personally om using latest faux's kernel, I'm on latest nightly - cm7

Don't forget to wipe cache, wipe dalvik cache, then flash kernel, then run fix permission, reboot, enjoy

Sounds they are referring to Faux's Kernel...
You have to match them up properly as CM7 just went through a few kernel changes and the Custom Kernel developers have to make them compatible. I think Faux has .44 out which is supposed to work...
Then you also have 4 options from Faux: Pre-OC/UV or Stock Speeds; and CM and DS battery drivers.

MIUI Users: I have a couple questions before updating to the latest

I'm currently running MIUIus 2.1.20-EN-Pyramid
Kernel 2.6.35.13 Trinity
Firmware 1.45.401.2
Recovery v2.2.7 RC3
So far I've been pretty stoked on this ROM (ARHD is the only other one I've tried but I'm sick of that interface). Here' s some questions I have before rushing out and flashing the new build:
Is the 2.2.3 build really much better than the 2.1.20?
Do I have to superwipe from recovery before flashing?
Is the 3.12 Firmware manditory for this new rom or just recomended?
I'm reading that people are having better luck with the Trinity kernel wich is what I've got installed (installed when I first flashed MIUI). Do I need to find a newer version than the one listed above?
I'm reluctant to update because I've got the phone totally dialed right now. Titanium backup has never been very reliable for me and I hate to loose my themes and settings. How can I retain all this info?
Thanks
For me, it seems faster. Better battery life. Flash this from, then flash the Trinity miui kernel for more stableness

overclock cm9

So i just installed cm9, and my phone can only go to 1188mhz so how do i over clock because i know the sensation can go to 1.6
Install system tuner and try to raise the value. If not, install a kernel compatible with cm9 and u should be good.
On some of the early nightlies I was able to use faux123's 005b3 asop kernel and overclocked to 1.78. I only used it on a couple of the early nightlies. I tried flashing it a few days ago and got bootloops. I think that was on nightly 01, maybe 30.
Stock kernel works fine for me. Overclock will probably be available sometime down the road. Someone on cm9 dev thread is running faux's kernel now, apparently without problems. I guess YMMV, or maybe that should be MMMV.
Isn't there a kernel less than 1.78 like 1.67 or something. A 1.6 kernel should be ok and u don't need to turn it up to max.

For CM9, faux is the only one that maybe works as far as I know. There is a mod over in the dev forum that overclocks to 1.5, I think. Haven't tried it, so I can't verify.
cm9 was great, but it wasn't stable yet and couldn't be over clocked
so i tried aokp that wasn't as good the screen looked too small and spaced out, but yo ucould over clock. And unfortunately without me knowing my phone was backing up my apps, ON MY DATA, so i owe virgin about 200$ now =_= for using 70$
In the end i went back to arhd, do yo uguy have any recommendation.
Use faux kernel 005b3 it will over clock it to 1.728.and it is stable and will run great.I have been running it for 5 days no problem.

First make double sure the kernel is compatible with your rom and operating system and firmware . Then wipe cash.and dalvik cash, then flash like a rom. By downloading the Kernel to the root of your SD card and flash through recovery. I like 4 ext recovery. After wiping you install from SD card then reboot. Hope this helps.
Of course do the download first, then wipe, then flash

[Q] Kernel for ARHD 3.4.2

Hi,
I have the rom revolution HD 3.4.2 on my tf101 and I would like to change the kernel. Which is the best for this rom? I tried guevor kernel but it doesn't work.
Thanks.
Any kernal ibwould use stock kernel because with tthqt rom stock works best
Sent from my PG86100 using xda premium
Ok, thanks for your answer.
There should be no reason why guevors kernel didn't work. Raymans kernel is close to stock with the addition of over clocking and more governors if you are worried about radical changes.
Actually, it's just when I flash kernel in CWM (wipe data and dalvik cache), my tablet reboot in the recovery each time and I have to reinstall my rom.
edit: testymeh and harmony kernel work but not guevor.

The only other kernel other than the stock one ive used is Guevor v22.6. If that one didnt work as well for you then you should try his v1.1 kernel. Just install it through your custom recovery. Best of luck sir!
I flashed the kernel but when I conect to my PC, my tablet is not detected.
Someone has an idea?
I'm using guevor's kernel v22.6 with ARHD 3.4.2 and it's working fine.
No SOD no RR. Team Rogue touch recovery.
Thanks, works great
