[q] my screen is black afer installling kernel!! - T-Mobile LG G2x

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.

So what kernels would work on any G2x?? Thanks for the tip idk all our chip sets are different.

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.

[Kernel][KG2]Bali Tweaks + OC! 1.28Ghz

I added kernel tweaks from raspdeep's I9000 OC and got our bali kernel to OC, I'm running at 1.2 Ghz right now. I haven't tested this in terms of battery life, but there's a good chance your battery life may be less. So use with caution.
This 1.2 Ghz OC feels smoother and faster than stock, and better and more stable than 1.28Ghz. If you tried the 1.28 and gave up, try this 1.2, it's much better. I removed the link to the 1.28Ghz kernel because it was causing too many problems for everyone, and actually being slower due to freezing and overheating.
Battery life and stability not guaranteed
Use setcpu to control your cpu speed.
Credits to Dr. Honk for bali original, and raspdeep for OC source.
THIS IS FOR KG2 ONLY!
I have flashed this both on stock and on a custom KG2 rom, they both worked.
link removed because it was unstable - 1.28Ghz
Updated 1.2 KERNEL: http://www.multiupload.com/3QPMQY476F
3:55PM 8/3/2011
I provide no guarantees that this will work, make a backup before you try this!
This was really only made for all the kids who kept asking for an OC kernel.
It has been suggested that the 1.2Ghz kernel may be more stable, so I would suggest trying that one instead of the 1.28Ghz kernel
Flashing right now . You beat me too it ;p

Flash through CWM as usual, I've tested flashing it and it worked fine for me, so it should work for you.

I'll try adding in UV mods later, but I have to go home from work for now.
Remember once you add UV to check the voltage . Just a reminder & The kernel flash's but it auto-reboot's & then stay's stuck on SK4G splash screen .

Well it works on mine, so it's not broken entirely, so something has to be different here. pulling the link until its more tested.
Now that I think about it, the issue might have been that you were all on rfs, rather than ext4
if you can get back to CWM you can just flash the old kernel
Ok reflashed old kernel. All is well.

How best to Upgrade

I'm trying to find out the best way to install a new rom & kernel.
Should you update kernel first then rom? or rom first then kernel?
Always rom first then kernel.
Sent from my LG-P999 using xda premium
Thanks for the info...
any particular reason why?
Because when you flash a rom it contains a kernel that will erase any kernel you flash before hand. So say your wanting to flash morfics trinity kernel for cm7, you'd want to flash cm7 first then trinity kernel.
With the rom your using.... does your APN work?
I've tried the Power+ Volume UP and still no APN connection. My settings are there an selected but it doesn;t connect.
It should work, faux's rom are second to none imho.
But for right now i couldn't tell you since my baseband is unknown and gonna be sent back to LG.
y doesnt faux have goveners in his kernel...

Kernels what to use and what they do?

Well I'm still fairly new to this and looking to learn a bit more . I am pleased with my current Hellfire 2.1 now I'm looking to exntend my battery life to the best I can and I was told this can be done with kernels, Soo I was hoping I could get some suggestions and anything that could help me out understand this a bit more.
I am currently using some Faux Kernel that came with the current Hellfire phoenix release.
Lot of people say to use Trinity with this Rom but no one says why nor in the xda page of this kernel say much about what it does, I like to be well informed before doing any changes.
also how do you install a kernel just download and install from zip from clockworkmod recovery like everything else? or is there certain steps to it?
First off this should be in the Q&A...

I'm currently testing the trinity kernel, The 1.1ghz one for the better battery. Using hellfire phoenix 2.1 so far its the rom I've enjoyed the most.
Any other kernel that anyone could recommend for the best battery performance I could get I'm pleased with the stock performance of the tegra 2 I have no need for overclocks.
Harsh kernel is the best. Flash it and see for yourself

Morfic's Trinity ELP if your phone can handle it as it varies phone by phone. But I also use Faux123's kernels and they work well enough.

Don't flash it because you're using a GB based ROM...

When choosing a kernel you should first know that they all are, in the most basic sense the same, but have little tweaks that make them all different. I know that the Trinity kernel has the Voodoo sound driver built in that is much better than any other driver. Also when choosing a kernel you need to just try a few and see how stable they are as not all phones are created equal. Some can handle the Trinity kernel and some can't (and same with all others). When you find one that works well with you just stick with it. And, as I like to say, to each his own.

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
