Kernel and ROM - General Questions and Answers

Kernel and ROM goes together right? I can't have just one of them? does it explain how i get black screen with just a kernel

Well you need both a ROM and kernel. But they often can be changed. However on some devices certain kernels only work on certain roms

Razor's kernel is the Defuse kernel but yes, you can flash the different kernel over your current rom. But the Defuse kernel does appear to have a couple bugs in it so I wait wait a little bit.
thank you very much
if the android version is the same and they are for the same device it is very likely for the rom and kernel to be compatable. exceptions touch wiz roms need touch wiz kernels, aosp kernels need aosp roms, sense roms need sense kernels. there are some rare situations where a rom and kernel build need to match like some gingerbread versions for the i9000 dont work with kernels from certain other gb versions. but since we only have 2 firmware builds and they dont have a conflict between them you should be able to use any rom with any kernel unless the des did something wierd to get a feature working.

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.

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...
or does he and i just downloaded the wrong 1 ...im using his kernel and my batterylife is terrible (very heavy fone user)
Its like that for all rom's and kernels for g2x.

Because the default governors of stock kernels are already very good.

[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.

Thanks yall u helped out alot.............I just installed the WEAPON ROM with the FAUX Kernel & im using Pimp my CPU for OC & UC........Besides Faux what kernels would be good to use on all G2x phones?

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...
Harshs kernel is for ICS ROMs...

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.

Well, I have no idea what kernel meant but I know that kernel control everything inside our phone, from brightness to phone call. Let just say that if our phone doesn't have kernel, probably its dead right now.
The difference of kernel 3.0.X, We don't know yet from the users side, but from the kernel it self, it will fix the most bug our phone has.
For the 3rd, same like above, we don't know yet but I'm sure it work on every CM9/10 ROMs. If you expect kernel 3.0 will work perfectly, nope it still has random crash and battery drain.

1. Kernel is the core of the OS, which mean it let the OS to control the Phone
2. Yes, due to JB rom base on android 4.1 and android 4.1 need kernel 3.x to work full function
So, we need the JB rom work good, we need kernel 3.x, i have a Galaxy W with kernel 3 CM9, it is hell alot faster.
edit, by the way, kernel 3 is not mean to fix the bugs. it is to let the new fuction functioning.

Kernel is actually the software which acts as an intermediate communicator b/w the phone's 'OS n Hardware'.. So possibly we might get from 3.0
full h/w acceleration
Speed imprvmnt
Finally since ics n later version's r based on kernel 3 there might be some performance improvements..
P.s: frm some linux form I came to know that, there is not much diff b/w kernel 2.6.* & 3.0.*... Linux jst change the no. system. From 2.6 they directly jumped to 3.0.. More info google
