[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.

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.

Frustrating to install a kernel

Hello Xda-developers community!
I have been having consecutive problems with trying to flash a custom kernel onto my Lg G2x.
I can successfully flash any custom ROM with ease, though when I go to flash the kernel, it installs successfully, but upon reboot the device never loads.
I gave it a good 10 minutes to load, though just sits at a black screen.
I'm not sure if I am doing something rong or not.
One of my attempts was to flash the Trinity kernel with CM7 already on my G2x, though upon successful installation, during reboot I simply get about a 5-10 second android robot logo, and then the screen just sits at black not loading.
If anyone would mind helping me solve this problem, or perhaps tell me if I am doing something wrong, I would greatly appreciate it!

If it doesn't boot then the kernel is not compatible with your rom. If you are running CM7 nightlies only the kernel supplied with it is compatible.

I have the latest CM7 release for the g2x at the moment.
I tried the Trinity Kernel with Bionix 2 and CM7, so far the same result.
I saw a you tube video promoting someone who had the Bionix 2 ROM and Trinity Kernel with each other. I tried flashing them both, but it never booted.
Are there any roms compatible with CM7 at the moment?
Or is it only the Eagle's blood ROM that has kernel compatibilities for the g2x.

The only kernels compatible with CM7 nightlies are the kernels packaged with the update zip for that nightly. Flashing anything else is just a waste of time and you are going to keep frustrating yourself to no end.

When you say the latest cm 7 for the G2x do you mean the latest nightly or the latest stable release 7.1? If you have the 7.1 you should be able to use the trinity ELP but if you are using a nightly build then you can only use whatever came with that build as Jboxer said already.
Edit There are a few that you can use for 7.1 not just trinity ELP just look in the thread for each kernel and they say which ROMS they are compatible with. Also eaglesblood 2.4 is based of cm7 so if it workes on EB 2.4 then it will work on cm 7.1. Also when you flash a kernel make sure you clear the cache and dalvik cache. And wehen you boot up for the firsdt time after clearing the dalvik cache it could take 10 min to boot up mikne usually takes about 5 minutes but I have seen it take up to 10 so keep that in mind.

I solved the problem, thanks! Now I was looking around for roms and I found an miui rom for the g2x.
I like the ROM, so any idea what kernel would work with that?

Under developement, faux's kernels (based off cm7). 3 different types, cm7 stable, nightlies and a different version for nightlies. Miui works with one of his cm7 kernels. I believe it is 44s

After flashing new kernel device don't boot

Hey guys
I'm running SlimBean 2.8.0 ROM and when I try flash a new kernel, device not boot. Logo Google pass and there isn't nothing more. Only backlight of hardware keys is on. SlimRom's boot animation is not show. I tried a lot of kernels (Matr1x, Air, vta2...) but no one was work. I tried wipe data and then flash a new kernel - no effect. Wiped dalvik cache - no effect. I tried to make clean install of SlimRom's (without Gapps) then flash new kernel - no effect again. Before flashing each of that kernels I make a clean install of SlimRom (with its stock kernel). Now I'm using stock kernel.
I need a custom kernel for USB host mode.
Any ideas?

Make sure you are flashing a cm kernel

+1 for that. At 2.8 SlimBean merged CM kernel code meaning you have to now flash the CM kernel and not the All Others.

I'll try this. Thanks
Edit: It works! Thanks again!

Can't boot custom kernels

I'm flashing roms for a very long time, but I ran into a problem, I can not understand:
I have unlocked my bootloader.
Flashed TWRP
Formatted all the partitions in TWRP.
I have flashed AOKP nightly 02/01/2014 but whenever I trie to flash a custom kernel (tried bricked and Franco) my phone won't boot. It's stuck at the Google logo.
How come?

Make sure all the partitions are the correct size as well as make sure the Kernel supports the ROM. If you read the individual kernel threads and do a search, the information should be available. Its been discussed that many ROMs have switched some code in the nightlies to not being supported by some kernels while others work (such as Chaos kernel working on CM ROM while Franco kernel works stock). Depends on your preference then once you find which are supported and which are not. There is also a thread (I believe in Original Development or the other development thread) that bridges the kernel support of some to work on the newer CM based nightlies based on the CAF/nonCAF system codes that are being worked on.

Because you flashed a kernel that is not compatible with the rom. Re-flash the rom and then find a kernel that is compatible with AOKP.

I was coming from the nexus 4 running AOKP and they have had a poll about caf or non-caf. They decided non-caf, that's why I thought Franco kernel should work (worked on nexus 4).
But I see I have to do some searching.
I thought the decision was already made by the AOKP to use aosp kernel.

[Q] Little help installing rom

Atm i have elementalx kernel installed and thinking about switching to franco when i install a new rom. I am on stock rom and will probably flash to Slimkat, will i just have to flash Rom + google apps and then elementalx/franco?

Read the op for slim. If it says to flash gapps then you'll need to do that. Then flash the kernel
