[Q] Do you usually flash a kernal before or after the rom?

Hi guys,
It's been so long since I have flashed a new kernal, is it better to flash them before or after you flash a rom?
are there any recommendations you fine XDA members have for kernals if I want to use it with the latest AOKP
Thanks for the help!

Since most roms come with their own kernel, I flash the Rom first, then whichever kernel I plan on using.

boot into recovery.
wipe wipe wipe
flash rom
flash gapps is needed
if want, flash desired kernel
reboot.
wait for all apps to sync,
if needed, reboot into recovery and flash a theme.

Kernel is always after the rom.
Rom's install a kernel themselves that will completely overwrite any kernel you had set.
I use LeanKernel. And stick to the stable versions.
But that's my preference. You'll have to flash a few to decide.
Kernel testing itself is a bit of a bore. You need to test each kernel for at least a full battery cycle to see how it responds for you.
Also keep in mind that you can tweak kernel settings like color control, sound control, undervolting, clock speeds, and cpu governors if you want more customization.

After the rom ... roms contain kernels so it overwrites any kernel installed already ...
Don't forget to wipe your Davlik Cache before flashing your kernel

Please Suggest a good order
custom Rom
Super Su
Gapps
custom kernel
or whichever order is good after ROM..?!!

Now, as for that kernel tweaking u mentioned, wut is the tweaking process?, & where is the kernel located?, & lastly, how would I navigate 2 it'z location? Thx a mill in advance my lady peace. P.S.

Kernal ??

Is it necessary to flash a Kernal after flashing a custom rom ?
I am thinking of flashing CM 9 or Liquid Rom. Which is the best kernal to flash with them.

-The correct spelling is kernel.
-It is not necessary to flash a new kernel with a rom. In general roms will package the stock kernel unless they note otherwise.
-I am personally a fan of leankernel because of the mission statement behind its development and the accessibility and speed of its update cycle.

Nope. Custom roms have kernels included, so you are not required to download a separate kernel. However, some kernels run better (ie, more fluid, less heat, reboots, etc) than others on the same device. It all depends on the silicon in your phone. If you plan to run cm9, I recommend sticking with the default kernel. If you're going with Liquid, use imoseyon's leankernel (the default) or franco kernels.
Edit: BTW, I highly recommend franco's kernel app, especially if you are new to the scene. It can download & install either franco or imoseyon kernels, making kernel flashing stupid easy. It also lets you overclock & undervolt, change governors and tweak color settings. And it is the easiest way to keep up with nightly/experimental builds. Not to mention it shows your support and encourages more development.

i say try them all, but for cm9 i recommend fugumod.

Thanks you all for your suggestions ...
finally going to try Liquid Smooth 1.25 (http://forum.xda-developers.com/showthread.php?t=1555667)
along with Franco.Kernel (http://forum.xda-developers.com/showthread.php?t=1367341)
...... One last question Which Franco Kernel to flash there are Milestone 2, Milestone 1, Nightly ??? Whats the difference between them ?

Also when installing extras for liquid smooth do i need to wipe everything again .. I am new to this flashing stuff
and does Liquid Smooth comes with a kernel if so which one ?

Latest milestone is the most stable. Nightlies are experimental. And no need to wipe.

@cldwar
Liquid + franco is a great choice. Liquid is an extremely polished rom. Very, very smooth with absolutely ZERO lag (it is called Liquid Smooth for a reason) and lots of customization & tweaking options. franco kernel pushes the smoothness to another level. Liquid & franco are both awesome devs who have been tinkering with android for a long time, and they both know their stuff.
Liquid comes with imoseyon's leankernel, which is a solid kernel (obviously, or Liquid wouldn't have included it in the rom). imoseyon is another well-known & respected dev that churns kernels at a dizzying rate. He must develop in his sleep. A lot of people prefer his leankernel, and you really can't go wrong with it. But like I said before, it really depends on your device. Your phone picks the kernel, not you. Milestones are the most stable versions. Nightlies are bleeding edge experimentals with the latest patches & tweaks that may or may not improve battery or performance. Since you are new to flashing, you might want to go with milestone 2 for a few days and see how it feels. On the other hand, you could jump in balls deep and go with the latest nightly/experimental
And you don't need to wipe anything before flashing the extras package.

If you have fastboot set up, grab official images from google and flash them.

doesn't matter,
infact if you flash yakju then you will get OTA as well. if you are in japan you can flash a japan radio on top of the rom.

Kernal?
I have been researching the many different kernels out there all day. I have been running GummyNex ROM's since I rooted my GNex. I really do like the options he has. I forget which version, but the battery life was amazing (which included the baked in kernel). I flashed to .0.9 and recently 4.0.4 1.0.1 and the battery life is like a V-12 Lamborghini. I just flashed a Franco Kernal and am hoping this fixes my battery drain issues.
Something has to give......

Use liquid rom with Franco milestone built ... gave me a 4+ hour screen time. Don't know why but the nightly version reduces battery life
Sent from my Galaxy Nexus using XDA

I'm running Liquid 1.3 and am using Franco nightly #143 and, so far, my battery life is really great. I was at 89% after 2 hours. I also want to try Milestone 3, that just came out yesterday and see how it performs.

Suggestions for flashing roms

Hi,
I want to install a custom rom to my Gnex. The only thing i have done so far is to change my device model yakjuwx to yakju (I unlocked bootloader and locked it again after the proccess).
I am going to unlocked it again and root my device.
However I don't know from which rom to start. I used to have a i9001 in which there is lttle development so everything is easier.
It 'd be very helpful if u could tell me which rom is the best or at least from where to start..
***sorry for my bad english

Try using TripnDroid rom n kernel...search on the forum please..
Sent from my HTC One X using xda app-developers app

Try latest rasbean build! It's superfast and the batterylife i pretty good. One of the smoothest roms I've ever tried. You can find it at fitsnugly.eutoskank.com, select rasbeanjelly, then your phone. Gapps is included I am using it with latest franvo kernel, r268. Awesome combination. But if you want a rom that you can customize very much, you should try out codename android, the nightlies or the stable version! Instead of Franco kernel you can try out Trinity kernel, the colors are so sexy man! haha. But you can set them on franco kernel too if you want.
I hope you find your own combination that fits you needs most
Edit: You can find the Codename Android nightlies here: http://goo.im/devs/codenamedroid/nightlies/cna_maguro Just pick the latest one

I was in the same place as you were a month ago. You'll most likely swap ROMs like socks in a few days or weeks. I've run CodenameAndroid (go for nightlies), AOKP JB and CyanogenMod 10. Of the three, CyanogenMod 10 is the lightest on tweaks and CodenameAndroid has the most, but that's not necessarily a good thing if you don't want to fiddle with everything.
For kernels Franco's kernel is good, get the 384MHz version, 268 nightly -- I've tested it and got better benchmark results if that's your thing.

Can someone suggest me a good ROM for it's performance and stability (stock look if it's possible) and a good kernel for it? I'm not asking for "the best ROM", I would just like some suggestions from you.

i have the verizon nexus and installed the pure android 4.2 rom. it runs great. but i cant overclock it and one of my friends has a aokp rom i believe that is still 4.1 but he can overclock it to like 1.6 or so. i would love to know if there is a clean stock-ish rom that doesnt have any fancy launcher or anything that i could overclock to beat him but still have 4.2. any help is great but if there isnt one its no prob.

If all your research tells you that the rom controls oc, then it's not for you, stay away from it for now.

You can use stock 4.2 ,just flash a custom kernel which is what actually allows the over clocking. Franco kernel is good. Then download a CPU control app from the play store.

The pacman ROM is pretty decent, you should go with a 4.1.X ROM because Google did an ehh job with 4.2 test away though, some ROMs are much different than they look

Isn't the pacman ROM in alpha stage?? That means it's not stable :-/

Minco ROM. Pure AOSP with franco kernel. Im also new to GN but I like this one quite much
Sent from my Galaxy Nexus using xda premium

I'm running CodenameAndroids 3.6 rom, and I haven't found one I like better yet. Tons of customization options. Love the navigation bar options and options to add and change swipe up shortcuts. I'm running Franco's kernel too, but haven't tried oc'ing. Not much of a gamer, so I don't feel the need.

What kind of franco's kernel? I mean experimental or stable? Any kind of oc?(cpu and gpu)

I'm running Milestone 6 stable. I'm pretty sure u can OC but to what IDK.

Now im using BuglessBeast and franco's stable kernel...i don't know if i'm crazy but some games are still laggy:-/ like Dungeon Hunter 3. What's the probleeem ?!?

I am in a similar position and didn't want to start another thread.
I am getting a used GNex tonight...
My start point is a Nexus S with CM10 nightlies and the Marmite kernel. Having Used CM7, CM9 and CM10 on 2 different devices, my temptation is to go for CM10 again. I am not a heavy user and don't play games on a phone, but the most important think to me is battery life (with smoothness a close second of course)..
Can someone please recommend me a battery saving kernel with CM10?
Or another good ROM / kernel combo?
TIA.
Sorry - I realise that I just killed a panda

Can anybody tell me if faux's kernels are OK?

[Q] Flashing New Kernel

Hi I was wondering what is the best Kernel for the T-Mobile version of the SG2 when it comes to battery like and performance. Right now I am running CM10 4.1.2 and its stock kernel that comes with the ROM. I am fairly new to this whole process so if I flash a new kernel do I have to wipe everything or just the cache? Please help me. Thank you

You shouldn't need to wipe everything but I do if I can. Ocd.
Also, some ROMs are not compatible with all kernels and vise versa. There is no best kernel IMO. Just test em out.

Like said before, there isn't a best kernel. But read through the threads and but can see what each one does and it's problems.
I would recommend lightning zap but u have to do some digging in the pages. It's stable, best performance and battery life
Also u don't have to wipe anything but it's recommended to flash after a new rom flash
