[Q] Backing up Kernels - Android Software/Hacking General [Developers Only]

So my Evo 4g has Fresh Evo installed and is overclocked to 1.26 ghz.
my question is, I know how to back up my Rom using Rom Manager but how do I back up my Kernel? I know that the Kernel I am using will not work with other Roms. I am very happy with my setup but still want to mess around with other Roms.
Also, if I restore to another Rom will it screw up if that Rom is not compatible with this kernel? Last thing, if i do want to go back, where can I get the stock Evo Kernel?
Please help.

From all my testing its seems that clockworkmod backs up the kernal as well. I have different kernals for all the roms that i use. someone correct me if im worng but my hydra kernal does not work with evervolv and when i swich between evervolv and stock roms the kernal changes too

So when you switch between Roms, do you use Rom Manager?
Thank you for your help.

When i switch I reboot into recovery then go to backup/restore and restore the one i want. so if i want my hydra kernal with stock rom ill restor that or if i want evervolv with the kernal it comes with ill choose it. I know its swaping kernals becasue evervolv wont boot correctly with hydra kernal

[Q] Do all kernells work with all roms???

Do all kernells work with all roms???:confused
htc desire
an does this kernel http://forum.xda-developers.com/showthread.php?t=682419
work with the rom:RCMixHD
Not all kernels work for all ROM's. Some are made up for Froyo, and some for Gingerbread. I read the OP and I did not see any restrictions, so it is probably fine for 2.2 and 2.3. Also, make sure the kernel is for your phone. You cannot use a kernel made for another phone. Make a nandroid backup before you flash.
Edit: I just saw you have a desire and the phone was from the desire forum...soooo you should be good..but like I said, you should make a backup before flashing anything.
kernel
I'm currently running the COS-DS 2.3.3 ROM with the latest BiffMod 2.2.1 Kernel. It works better than the kernel, which comes with COS-DS, but not every kernel will work with every rom. It also depends on your phones hardware.
nope. the kernels are set for certain types of roms.

How about mix the 2.2 kernel with 2.3.3 userland?

[Q] Updating Kernel

I was just wondering that if I am going to update my kernel is it necessary to re-install the rom or do I just install the zip with clockwork and away i go? I've searched the forum and couldn't find anything regarding it, I would appreciate the help! Thanks.
you can just use CWM to installed the kernels without installing the rom but there might be some compatibility issues, so check before doing it.
Ok because the reason I'm asking is because I have SupeAosp with the Trinity kernel but I'm thinking on either upgrading for Trinity 12 to 14 or trying out James Bond Kernel and I thought that there might be some prep work involved.

just flash the newer kernel on top. be sure its compatable with the rom. if you do have issues, just reflash the rom(that will bring you back to the roms "stock" kernel).
In this case you can test out different kernels but make sure you have the trinity kernel file in the root folder in case which ever kernel you do flash doesn't work out.
In such a case you would just boot into CWM and re-flash the morfic kernel.

Thanks for the insight, I look forward to testing out many kernels!

[Q] [i9020-T] Trinity UV Kernel Flashing

Hey everyone I'm kinda new to the whole kernel flashing business and I'm trying to flash the UV Trinity kernel to my Nexus S. From what I've read I only need to flash the zip from recovery without having to do any sort of wiping. The main problem when I tried this is that the phone went into a boot loop and wouldn't go past the boot animation for the kernel. I'm not sure if it's because the kernel is based off of 2.3.4 and I'm currently running CM-7.0.3. Morfic's thread indicated that the kernel was made for CM7 so I don't know what's going wrong here.

You have a ROM based on 2.3.3, meaning it's not compatible with a kernel made for 2.3.4.
Try flashing the latest cm7 and then the kernel.

Would it work if I tried a CM7 variant that's based off of the 2.3.4 source? I'm going for a stable phone and unsure about the nightly builds at this point. If not I'll probably just wait CM to update and release the rom.

it should work on any 2.3.4 cm based roms.

Kernel advice

Im currently using the miui rom with stock LG kernel. Whats the best kernel to use with this rom? Sorry if this has ben asked b4 im a total noob at this.
Since its a 2.3.5 gb rom try a kernel for gb 2.3.5, try faux's kernels for cm7, back up first in case something.
no dont use fauxs its known that your audio wont work properly, that one was made CM7 specific, even though its CM7 based it doesnt work.
im also wondering this
i came from a g2 and have no idea about all this kernal noise for this phone

[Q] Custom Kernel no Rom?

Just need a short straight and to the point answer. Is it possible to have a kernel to overclock the Nexus S to 1.4 GHz without a ROM. I am on stock android 4.1.2 rooted. I don't want to install a ROM. If so please tell me which kernel, if it's stable for everyday use and how well it works. Thanks! Have a great Day!
As long as you have a custom recovery, you can flash custom kernel. Try trinity (derkernel.com) its experimental but very stable. Though it does not have bigmem. Also you have to be aware that your phone might not be able to handle over clock till that high and therefore reboot repeatedly. Hope it helps.
