Well to start. You can read the stickies, the how tos, and watch some of the videos.
Then there is also that g o o g l e thingy.
That would really help. It will probably keep you from turning your device into a shiny paperweight.

I've not had good luck with custom or source kernels. I use oudhs recovery and do a backup within recovery before flashing a kernel. The only combination my phone behaves with is stock kernel. I don't know why nor do I have any speculations. My phone just doesn't work right with custom or source built kernels. The phone either heats up fast or the Google keyboard I use starts acting flaky, so that's why I stay stock rooted hotspot mod with custom recovery. This phone is a totally different beast than my s2.

I agree. S4 acts way different than my S3 as far as flashing things go. Seems the S4 is way more sensitive and does some wonky stuff sometimes.

First, download a custom kernel such as Chronic or KTweaker, then nandroid, wipe caches, flash the kernel zip, fix permissions, and reboot. ROMs come with their own kernels; to get your original kernel back, just reflash your ROM.

What ROM/kernel combinations do you use? The only buggy kernel I've used is KTweaker. On Carbon 4.3, it reboots whenever my phone attempts to stream video. It may help to change your governor, especially if the kernel's default is Interactive.

i have come from Xperia X10i. where i could flash roms in minutes with Xrecovery thx to J&Z & Trip for his wonderful roms without the need of connecting my phone to a pc.
I am a bit confused now. i have made up my mind about custom roms, Villain and Lightening. i want to try both.
I dont want to damage my SGS2 as it looks very very delicate. My questions is do i have to use ODIN all the time for changing and testing roms? or is there an easier way. The reason for this question is as:
My X10 usb port got damaged due to flashing different radios/basebands for different roms and i decided to get SGS2.
Odin is probably the easiest way to flash a rom but most custom ROMs are flashable with clockwork recovery. You first have to flash a custom kernel with odin to get clockwork though.

Depends on the rom dev, if they make the rom flashable thru cwm recovery (cognition,batista etc) or odin like litening, villain.
Honestly both are pretty simple and quick. I have all my user apps, touchwiz config backed up thru titanium backup. So it only takes 5 to 10 mts to flash a new rom and restoring apps.
And don't worry you are not going to brick a samsung phone, odin will always rescue you if you can get into download mode

that's good, if i was to flash your ROM for example do i need to install CWM on my GS2 first?
my old phone was the HTC One X and I remember having to repack the kernel for the rom I was using
1) is it the same here with the Nexus 4 after rooting/unlocking? any automatic repackers out there?
Also,
2) do I still need to "fastboot flash boot boot.img" everytime I flash a new rom
PS pretty excited about getting back into the android scene. my nexus 4 is coming in tomorrow.
From what I know I never had to repack any kernel on my nexus phones. All you need to do is run the unlock command once through fast boot and you can flash whatever you like. This phone is made so you can run what you like without jumping through hoops like the branded phones.

can anyone second that?
once the bootloader is unlocked, and have a custom recovery installed, you can flash any nexus 4 kernel you want(compatible kernel). you dont have to repack anything.
Thanks simms22

if thats the kernel that you are flashing. theres only one that i can think of that requires flashing the boot.img, all the others are flashable via the recovery. but, to answer the question, after every rom flash, youll have to reflash your custom kernel, as the rom will overwrite the kernel that you are running.

Coming from a One X myself, I can confirm that you don't need to go hunting for a repacked ramdisk for use with your kernel of choice.
As the Nexus is fully unlocked, (not some half-arsed partial unlock that was the case with the One X), all the kernels can be flashed directly within recovery

THANK YOU for your responses guys.
any opinion on the best rom/kernel available right now for the nexus4?
I would really like the features of AOKP and cyanogenmod but hates little bugs.
Probably might stick with stock rom but maybe a franco kernel for now??
rasbean jelly rom, trinity kernel. stock rom is good too. but theres no best, theres whats best for your needs. experiment with a few different roms/kernels, find what you and your device likes best
I have the ATT 16G S4 variant. The device is rooted, sim unlocked, and has a twrp recovery. Two questions,
1. I have made a back up in twrp for boot, system, and data. But I do not see an option to back up the stock kernel. So how do I make a back up for my stock kernel? Or is the stock kernel already backed up as part of system?
Now I want to try running the Omega custom rom on it. I know I have to also flash a tw based locki patched kernel for my att variant since the bootloader is locked.
2 What is the best kernel for running Omega on ATT?
Thanks!
Your kernel is backed up with the boot when performing a nandroid. But "best"of threads are against xda rules man. Gotta try for yourself

Right, I meant, what are some of the tw based kernels which will run smoothly with Omega rom on my att device?
Not sure. There is only two kernels for tw and im pretty sure it says in in the link below you have to use a specific one
http://forum.xda-developers.com/showthread.php?p=41834056
Edit. It says must use loki kernel. I skimmed over the faux kernel thread and didnt see anything about it being loki'd
So use KT kernel

I read that Adam and faux both work on ATT as well. I am on KT right now. I'll give the other two a try later. To see which one I like best.
Thanks!

All of them work perfect, each phone and what you run on your phone affects how the kernel will work for you...try each one, give 24hrs per kernel to see if battery results and such are for you.
Good luck

Thanks! I have been on KT for the past couple of days. Everything seems fine so far. I will try Adam and Faux in the weeks to come. I did notice the phone heats up pretty quickly after using the swipe to capture screenshot function. Is that normal?
Where can I find the Adam kernel download for AT&T S4?
I have recently been switching my ROMs up alot and have been having issues going from AOSP back to TW through regular flashing of the ROMs.
I generally don't have any problems switching from TW to AOSP, but whenever I flash the other way I am just left with a black screen after the Sammy logo.
To effectively get TW back on my device I have to Odin back to stock and then Odin flash a recovery and start from scratch.
I was curious as to the rest of the communities experience with this as I may just be missing a crucial step when switching between the two systems.
I usually format the /system and do a factory reset and wipe both caches
Does anyone else have a problem like this?
sounds like a kernel issue since your wiping system and data and cache? so i wiould flash another tw kernel when going back to tw if it doesnt boot, i use the kt kernel.

Supposedly, there's a way to make every ROM SS compatible. I think it has to do with removing the boot.img, but I'm sure there's more it than that. I've seen people complain about there being no SS ROMs, then someone mentions this solution, but nobody takes action. Honestly, it's going to be up to someone that has a locked down device to start putting out these SS compatible ROMs.
Then, you will run into kernel issues like we used to run into on the older SS ROMs. Let's say you want CM10.2 that is 4.3 based. Your stock ROM is 4.1.2, so you'll run into kernel issues like an inop camera, WiFi, etc. Honestly, your best bet is to find one of the 2 SS compatible stock ROMs that are the same kernel as you and use Xposed to modify it. There's someone on DroidRzr that used Xposed on his X with a stock ROM and he has been able to load up the custom CM themes.

Yeah... It can't be that hard - all the other motos have SS CMs out. Just gotta have someone with the knowledge and need/want to make it happen
