Installing a Kernel - Nexus 7 Q&A, Help & Troubleshooting

Well i am very new to all this stuff since this is my first android device. Can anyone please teach me the steps on how to install a kernel on my rom. I do understand that the kernel should be compatible with the custom rom i have, given that I would really like to learn how to do it.
Last time i tried i almost bricked my n7.
Thanks in advanced.

Try using the search function, there is a shed load of information on here rather than asking for your hand to be held.

[Q] Please help a noob

I really need an overview to orient me.
So I want to flash a ROM on my Epic because I want good battery life and I want to get the crappy built in apps off, and I want to have all the goodies.
I guess I need a Kernel too? from what I see.
So then I downloaded Epic Experience 1.1.9 and Mixup Kernel with voodoo.
So now how to install?
I guess I need ClockworkMod? What is that anyway, and why do I need it? Does it install both kernels and roms? or one or the other? And does it matter what order I install the kernel vs the rom? or do I somehow combine them and install both at once?
Can someone please give me a walkthrough or overview of the whole process? I can not seem to find this kind of information in my searches. and I am feeling kind of overwhelmed.
Thanks!

Suggestions

So I just picked up a tab today and of course the first thing to do is root, so just a couple of questions, I have a SGS and am on a CM7 ROM, so Im not a complete noob, although this next question may be a noob one... I was looking at the VFP OC kernel and was wondering if it was rooted, meaning can I just flash that kernel and be rooted?
The useragent mod looks to be a no brainer as far as having it, what other apps or mods would you guys consider standard ones to have?
I wont be doing anything till I fully read over what to do as far as rooting or anything else goes but it seems pretty straight forward since we are using the same tools i.e. CWM and ODIN, so just looking for suggestions ATM
Thanks ahead of time

Welcome! Use the rooting video guide to get CWM on your GT10, once you've done that just use the CWM program to flash both ROMs and Kernels.
As for the mods, you don't need them as they are already baked into most of the ROMs. Try Starburst or Task650 for ROMs, And definitely use pershoot's Kernel (and get the SetCPU app to overclock, you can get it free somewhere in these forums).
Have fun!

Great thanks for the help and direction

I9100G users Unite!

Introduction
I've had my I9100G for more than a week now and to date there's no hint of anyone working on a custom ROM or mod for it. I guess we'll have to resign ourselves to the fact that it's not really a popular model for the regular devs and if we want to get some mods or custom roms on our phones, we have to do it ourselves. I'm currently working on customising my phone, but since I have a day job and little actual experience in Android, it's going to take some time before I can put anything out. So I'm inviting fellow I9100G users to join me in the effort to get some mods developed for the I9100G.
Kernel
Firstly, the kernel. AFAIK, there are two available kernels so far for the I9100G - KH4 (Android 2.3.4) and KI1 (Android 2.3.5). There are rooted versions for both, but as of now only the KH4 one has CWM recovery. In addition, Samsung has released the source code for the KH4, but I'm yet to find the source code for the KI1. I'l like to develop for the KI1, but without a source code and CWM recovery for the kernel, efforts are limited. So I appeal to anyone who knows where we can get the source code for KI1 or can help get CWM on the KI1, please respond!
Mods
So far I've deodexed my phone running on KI1 and managed to get the battery percentage mod on it using the UOT. That one's pretty simple. This weekend I hope to try some more mods like the Advance Power Menu, for one. Once I get that done, I'll share on xda. Appreciate suggestions on what mod we can apply that's useful, but too complicated. If anyone manage to produce mods for your I9100G, appreciate if you could share.
Hopefully once we have a few mods done for the I9100G, we can consolidate them into a custom ROM for our phone.
Let's work together to make our phone better!
I would like to join with little experience on android .
I understand our target is to make custom Rom for the g model, but do you think its we can make it possible to flash other i9100 custom roms with sgx 540 processor ?
Can we have a list of things to start with to acheive that?
Btw, i tried deodexeding and i didn't success. Any advice on this .
Thanks

Hi ss219100g,
We can't flash I9100 custom ROMs into the I9100G. I tried flashing VillainRom onto mine, but I couldn't make it work. Needs someone with more knowledge and experience, I suppose. All I can try right now is try to apply various modes I pick up from xda onto my phone.
So far I've managed to apply the Battery percentage and Advanced Power Menu mods. I'll share them later today. I'm still looking around for the next thing to try. Any suggestions?
For deodexing, I used xUltimate. The link's here:
http://www.droidforums.net/forum/xeudoxus/47283-release-xultimate.html
Basically, I copied the contents of /system/app and /system/framework to \origi_frame\ and \origi_app\, run the tool, then copied the results back onto the phone. Remember to delete the *.odex files in the phone.
hi, i one of the new sgs2g user.
i would like to join and hoping if we could ever make some custom rom for this version.
but i still noob bout android, and this is my first android phone.
i was able to root my dzki1 kernel, using insecure kernel and abd command, but unable to flash cwm recovery, is there way to flash it?
and other thing, what is deodex and odex? i try google,but could not understand

It's not the one from Odia's thread, is it? I tried that one but it's rooted, but doesn't have CWM.
so meaning to say that until to-date there are no available custom ROM for the GT-I9100G devices??

Correct me if I'm wrong but I'm fairly sure the only issues you have are with te modem that's installed causing degraded data network service. I can test tonight as I have a 8100g laying around atm.
Scratch that it was the 9100T i was thinking of

In short:
1) Root
2) Deodex - use xUltimate
3) Use UOT Kitchen
Sorry I can't give more details. I'm away from my PC right now. Please search for the above tools.

have you guys tried flashing any custom themes ?
the only one working for me is battery %
and is there anyone working on an optimized kernel ? MyGKernel is very good but it isn't optimized and not overclockable as far as i know!

anyone tried this custom ROM? encountered the yellow triangle?

i did and that's normal, you get a yellow triangle because you installed an unofficial (insecure) rom or kernel, don't worry about it, it doesn't affect the stability of your phone in any way, it's just for saying that you have intalled a custom feature (rom or kernel)!

There are Roms posted in the Dev section. ICS Stock also.
Your best bet, would be to look at the directory structure on some stock rooted roms, and also look at the updater script for them.
This will give you a good starting point on what to change in your script as far as BB and SU.
MD
Also, I highly recommend you look into the android build system.
Yes its complicated.
yes its hard at first.
but there is only so much you can do to mod an already compiled rom.
even with little coding experience you are able to do a lot when you have access to the source!
plus, if you fix something, you can submit it to have it fixed for everyone.
between this guide and our CM9 thread, you should be able to get started. we have some basic setup instructions over there.

[Dev] Creating custom Kernel

Hi,
I am a C++ and Java devs. I just got my first Android device, Google Nexus 7. I had an iPad before but I sold it to try Android . So here am I
I would like to know if there was any way to learn how to create custom kernel ? If there was any help anywhere? Documentation or whatever? I never coded anything for Android yet. My wish is to be able to create a Kernel that allows overclocking. I tried the Clemsyns Elite Kernel that allows the user to overclock to 1.8Ghz. My goal is to try to get even farther, try to reach 1.9 Ghz or 2Ghz.
Thanks you
Up please
So many good devs in here please
I'm not a dev but I've seen similar posts to this before. Try searching the forums (don't limit yourself to the nexus 7 forum) and I bet you will find some links to info on kernel development.

There are plenty generic guides availible.
My simple google search yielded this: http://forum.xda-developers.com/showthread.php?t=1039854
Thanks for all of your answer
I should be able to compile a kernel by now thanks
But I was more looking for help in modifying one, since it is a really huge code, il would take a long while to read all part of it and even thought I would like to read it, when you dont know a thing about it, it is pretty hard to fins where to start x)
