Kernels and ROMs - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Hi All
Sorry if I have to ask a dumb question here. I'm currently using Stock Samsung ICS 4.0.4 ROM and I have just installed HydraCore v5.4 kernel.
If I install the HydraCore v5.4 kernel, does this mean I always have to look for any future ROM WITHOUT a kernel?
I understand that many ROMs come combined with a kernel packaged with it so what do if I want a particular ROM but also want to keep HydraCore?
Thanks in dvance.
Trevor

there is no such rom without a kernel.. all ROMs will have its own kernel. but then later u can change it to ur choice. Hydracore is compatible with most of the ROMs.
so if u want to keep hydracore.. u need to install the rom first and then change the kernel manually to ur choice

A rom can not be completed without kernel.
You see kernel is like backbone and basic thing required by rom.
Hydracore is good.

[Q] cutom kernel

I'm looking for a kernel thal will be working properly with stock rom
you can't have custom kernel with stock rom, you will screw up your phone
instead of custom kernel, find custom rom, improvements will be better

Stock rom cannot work on custom kernel... choose a custom rom or use stock kernel with stock rom!

Other question. wich kernel will be better for froyobread?
You will need a rom for a custom kernel. The kernel on my x8 is alfs v7 and is very good
and after install the custom kernel we can back to the stock rom?
No, stock rom doesnt works with custom carnel.

If you mean notecore kernel.. It is safe to flash roms from there as it has MMC_CAP_ERASE disabled and you can perform all the necessary wipes in order to flash the new rom

Notecore is safe but not any ics.kernel is safe to flash cm base ROM
Dont understand why op asking someone tried, why someone flash from ics when it can brick device. Just to try brick?

i'm sorry cause in a cm10 based thread i asked if it is safe to flash cm10 with notecore kernel and someone said that it's a safe kernel..So what do they mean by that? just finding a way how properly flash cm9 or cm10 if i'm on kdv7.1 ics and my kernel is notecore v13.. sorry for the misunderstanding....
i meant notekernel by gavin..
Notekernel is safe means you can safely wipe, flash CWM, can take nadroid backup/Restore on ICS ROM only.
Here in your case this safety have no concern. Notecore is TW based ICS kernel. You can't flash CM based ROM on any ICS based kernel/ROM.
To flash CM based ROM, get GB ROM/Kernel + CWM and flash CM based ROM using that.
Yes. Flash using pc odin, then root and install cwm, before flashing cm9.

That is 100% wrong,
you CAN flash CM{9,10} from a safe kernel, be it SpeedMod, franco or NoteCore, exactly the same way you can flash a TW rom from a CM kernel, as long as it's a safe kernel you can do whatever you want.
Now, if you flash NoteCore *after* you flash CM, your device won't boot, however you can always use the recovery to install a CM kernel or just a TW rom.
You do NOT need to flash a whole GB ROM, you can just flash the kernel and boot into it's recovery.
Also, you do NOT need a GB kernel or Abyss to flash anything as long as you have a safe kernel, aka SpeedMod, NoteCore, CM9/10, Thor, etc.
Your statement about flashing a whole GB ROM just to flash CM is misleading and wrong.
I still appreciate all your useful posts.
@PierreTech, it is 100% safe to wipe and install CM from NoteCore.
Steps :
0. Do a nandroid backup or a titanium backup. (optional really)
1. Reboot into recovery.
2. Do a factory reset.
3. Install CM9/10/whatever.
4. If it doesn't include google apps, make sure you have the appropriate zip file and flash it too.

Hehe dr.ketan I gotta agree this guy... You can use notecore kernel to flash any ICS custom rom... Aosp or tw.. As when you flash the rom via cwm the rom will flash its own kernel... In the case of CM9/10 the proper kernel will be flashed along with the rom overwriting notecore/speedmod..
But I can not agree the tone he does make things clear.. He could just kindly say no dude this works this way or that...
I'm sure you know way more things than me or him but in this little thing they guy its right

I meant no disrespect to dr.ketan, without his great guide I wouldn't have been able to root my phone.
Oh, i really dont mind. It.is possible i may not knowing everything . My opinion was just based on Instruction on cm9 thread where it is mentioned that cm based rom shudn't flash on ics based rom, and that only thing i took into reference. I never have used any custom rom so may be not aware of fact, but this also be useful if such clearification to be made on installation instruction on op of cm rom thread, as really i m feeling awkward to go against developers instruction.
Just to edit :
@life.eq.null
You finds my statement to flash full rom misleading and wrong, but actually
I already used word 'GB ROM/Kernel' to flash.
That just means either rom or kernel. I never said you need to flash only ROM. I showing you one possibility, if someone on Non rootable GB ROM, then it will not be easy task to flash Full prerooted/rootable ROM to get CWM? in that case it is niether misleading nor 100% wrong.
Now here i am copying text written on CM9 thread installation instruction
Make sure to run CM9 or an AOSP-based ROM : FLASHING FROM STOCK ICS OR ROMS BASED ON STOCK ICS WILL RESULT IN A BRICK!

Now if my statement is 100% wrong. totally misleading then you should head up to developers of CM9, to edit instruction in more clear way. b'coz here ROM itself said to avoid, no instruction about to use safe kernel mentioned.
I am agree your information may be recent and experience based, even i can say may be better and useful to users who are on safe kernel. But that doesn't make older instruction wrong and misleading, when till now everybody following this instruction which is instructed by developer only.

I think they only talk about the Kernel, not about the whole rom. I flashed many times a cm9 rom on a stock ics rom, but always AFTER flashing through CWM a safe cm9 kernel, or abyssnote4.2.
from ics stock, usually I boot to recovery, apply the cleaning script Sybr, flash my safe kernel (do not reboot, it will work now), do the 3 wipes, then flash new rom cm9 based. then reboot.

best kernel

Hey guys im a newbie to captivate and its developments and i need your help..............
i came from the htc g2 where there is no needed for flashing kernels for backing up roms/restoring or for wifi issues, everything was pretty much straight forward after root , but with the captivate you need a specific kernel for somethings to work...i need to backup roms and restore it......so my question which kernel comes alreaady rooted/hack to flash with odin and support wifi,clockwork,backup with clockwork recovery and everything ?
plus after flashing the kernel can i flash a recovery via rom manager?
i want a kernel that supports must miui roms and asop roms (ex: ics, jellybean)
and flashing kernels dosent break/erase root right?
PS: does a rom come with its own kernel?
Devil3 kernel 1.4.1 work just great for my JB MIUI 2.9.7

do i lose root or have to root everytime i flash a new kernel
or when i flash a rom
Devil Kernel is best on JB ROMs. Corn Kernel on GB. Every ROM comes with a kernel in it. It depends on the ROM. Reading is important.
Ok...so I rooted with corn kernel and flashed xm7...but asphalt 7 is too slow...can I flash a kernel to make the game faster ex: devil kernel and keep the Tom with root

Can anyone help a noob here?

Hi All
Am still trying to get my head around flashing FROM An ICS Custom Rom to a JB Custom Rom.
I have read lots of posts about this.
I am currently on CrashRom V12 and HydraCore Latest safe kernel, but want to try Paranoid JB Rom or similar. When i read
the OP Instructions its always says
Make sure to run CM9 or an AOSP-based ROM : FLASHING FROM STOCK ICS OR ROMS BASED ON STOCK ICS WILL RESULT IN A BRICK!
Can anyone explain what this means, because i thought if i was on a safe kernel I could flash any Custom Rom be it ICS or JB,
obviously after doing all the wipes in CWM???

yes u can proceed from where u r.. that warning seems to be when the stock ICS kernels were dangerous

[Q] About Hydracore

So I'm still pretty clueless about a rooted phone and I've had Ultimate XXLSC for months now.
Questions
1.) I can't help but think that when I rooted and flashed Hydracore, on the about phone > kernel version, it says Hydracore (I don't remember the version). But when I flashed Ultimate, the kernel name changed. It now says 3.0.31-593490 [email protected] #3 SMP PREEMPT Tue Nov 27 02:33:05 KST 2012. What happened? I didn't do anything besides rooting & flashing Hydracore and a custom ROM.
2.) Since the kernel name changed, I assume that the custom ROM changed the kernel (or maybe not. I really have no idea). Do I have to re-flash Hydracore and then flash another custom ROM?
3.) Can I really flash any custom ROMs (namely TouchWiz, MIUI, CM9, CM10, AOKP, ParanoidAndroid) with Hydracore kernel (because I plan on flashing JellyBam and some other ROMs I can't remember right now)? Do I need to flash a specific version of Hydracore (if there is any) to be able to flash a certain ROM?
Thank you for the patience and time to read my n00b questions.
I don't wanna look dumb with a bricked Note because I didn't ask/consult someone about my concerns.
No you don't need to flash the hydracore kernel again. Right now you are using a custom rom so it's already with the cwm from where you can falsh another rom

Thanks.
About my 3rd question, can I flash ANY custom roms? Why is there a custom ROM that says "Make sure to run CM9/10 or an AOSP-based ROM : FLASHING/WIPING FROM STOCK ICS OR ROMS BASED ON STOCK ICS WILL RESULT IN A BRICK!" What does Make sure to run CM9/10 or AOSP based ROM mean?
It's just a example for making sure the flasher must be on a safe kernel. They simply mean don't wipe from stock ics kernel. It can be any custom kernel you can do wipe and flash any new custom rom
