[Q] Kernel compatibility rules ?

Hello,
I'm looking for some info on the things I should check before flashing a kernel on my Note...
what's important ?
what versions are compatible ?
how do you find out ?
it's a french phone with the following characteristics :
Baseband : BUKJ1
Kernel : KJA
Firmware : Gingerbread 2.3.5 stock
I'd appreciate a "universal" answer or link to some info on this, so I can see for myself next time I have a choice to make on this, or at least a tip on which CF kernel I'm supposed to flash to avoid bricking it
thanks !

sorry wrong forum - delete

Even I have the question!
Not Wrong Section!
What if I install another Kernel on my Note?
My current Stock kernel is KK3 what if I installed another one like the one of the following?
KJ1, KJ4, KJ6/KJ7, KK1/KK2/KK3/KK4, KKA, KK9
Would it brick? OR Just do crazy stuffs like Network incompatibilities, H/W Module errors?
Would it Still Work?
And are kernels just Different coz they are from devices of different locations?
Need Help on this !

I stumbled upon some short info in a reply, and tried it a few times myself.
so, baseline is that your kernel MUST match your ROM version, or closest possible, as long as you do not yet have a custom recovery installed
(because if you mess things up then it's -best case- download mode and odin flash).
I was on KJA, flashed a KJ1 kernel and had a few problems at boot but nothing that prevented me from using the system.
(nb : numbering system is 1-9 then A-Z, so KJ1 is 9 versions away from KJA, but a lot more away from KK1)
when you have a rooted, recovery'ed kernel, you can flash an entire ROM at once, which usually have matching kernel and system versions.
in this case, you have no problem since both are made for each other.
I may be wrong but it seems to work that way.
in your case I'd flash any kernel in the KK# series (preferably KK3 since it's the closest one to your original kernel), but only if you plan on flashing a rom afterwards.
it's useless if you don't, anyway.

Thanks For the Answer.. Just to confirm,
I'm one of the HTC Dream user's & used to create ROM's & MOD's
Had ported 3.0 to Dream.. with zrFreak and other's So I'm interested into this:
Can you Explain The PIT, CSC ... all those stuffs ?
Just wanna know what Refers to what partition..

nope, I don't know much about Odin flashing, been following tutorials when I needed to mostly...
keep in mind I'm only a user, not a dev =)
(although one that has done quite a bit on his phones so far and is not afraid to try or code a bit)

Ah lol okies...
Coz I'm planning to start customizing SGN making new ROM's...

Maybe this post might help. It has some very specific statements about kernel & rom versions at the end of the original post.

[Q] how to deodex stock rom la6?

Hi,
I've tried several custom roms, while they are much faster than stock rom and i do find faults in them so always go back to stock rom.
However I want to deodex my stock rooted rom. the reason for this is that i need this patch for arabic on my phone.
http://forum.xda-developers.com/showthread.php?t=1424144
can someone help me to do this, all other threads are for other phones, is the method the same? and are the requirements also the same?
finally, if there is a way to get arabic full and not broken up like what i currently have, can some help with that instead, because that is what I really need.
cheers and thanks in advance.

You have 2 options mate:
1. Easy way:
- Download a stock, deodexed and prerooted ROM from [ROM] Stock ...LA4,LA6,LB1 ROM[Stock Deodexed & Tweaked Version]
- Go to that patch thread you posted and get the patch for the ROM you downloaded
- Flash and profit
2. Hard way:
- Go to [GUIDE] dsixda's Android Kitchen - Now with SGS2 support (Windows/Linux/Mac) and get the kitchen up and running in your machine
- Deodex your ROM by yourself
- Get the Arabic patch
- Flash and profit
EDIT: You actually have another option if all you're looking for is only Arabic support:
- Got to [STOCK ROMS] N7000 All stock ROMs + install + Root guide All at 1 place,Latest XXLC2
- Download the ROMs with the region code of JPXX (where XX is e.g. LA)
- Flash and profit
However, you may want to get the directly rootable ROMs to gain root and CWM recovery after flashing but never mind this if you don't care about root

Thats not actually hard mate and you dont deodex it.only the script does.The actual way is to use smali/baksmali.Just for your info.And yeah the easy method is to flash stock,deodexed rom

Well I've been using smali and backsmali for a long time but that's not for everyone and dsixda's kitchen is a great way to start learning about cooking ROMs

thanks mate, you've been a great help, i might as-well use the easy way. but first may give the hard way a shot, I want to learn about all this stuff, coming from the n900 its all interesting.

Yeah But I bet we can never learn by using scripts though the scripts are great .Ok no off topics anymore.

as most of us now have knowledge that the ics official rom is out but only the german one, is there a stock rom which is pre rooted and pre deodexed? just like what's available for the GB rom through here.

[Q] First-Time Custom ROM&/Kernel, need Answers

Hello
I've spent the last 24 hours browsing the O2x section of XDA, and decided that I might change the ROM and/or kernel. I'm considering either Paranoid Android or DjangoManouche ROMs with the KingOfBirds Kernel (If i go with DM) or Kowalski Kernel. However, I have some questions that I just can't find the yes/no answer for. Would anyone be able to answer these for me?..
1. I am running Stock Rooted ICS V30A with CWM v6.0.1.5, busybox and adb installed, which I assume I achieved through steps 3 and 8 on the AIO toolkit because I didn't do anything else.
Does this translate to "I am on the new partition layout with EXT4, have cwm recovery and can proceed to install kernels and ROMS for the new partition layout"?
2. I generally use my p990 for gaming, movies and internet yet still using it as a phone at school. None of the kernels (Kowalski's or KingOfBirds) I am looking at using state whether or not they have Tegra H/W acceleration support, which I do not want to loose. Do the above/all kernels for the p990 support H/W acceleration? :fingers-crossed:
3. Do the kernels and ROMs above still allow me to edit vold.fstab and have a 32gb internal memory from my sd card?
4. I see a lot of people saying CM10 is the best, but a lot of posts with questions and fixes for bugs with it. Any users of this one able to tell me if it is stable and would be suitable for me (see question 2)?
And if you are using DM or Paranoid Android, what are they like for someone who wants a nice fast stable O2X?
5. Will backing my apps up with Titanium and zipping my internal storage be enough to save my game data? $9m on Hill Climb Racing I don't want to loose.
6. When I am changing, should I format my phone in cwm, and then flash the kernel after ROM? (eg DM -> KingOfBirds)

hi there! i'll try to answer some of your questions:
1) you are on the new bootloader and should flash rom's for this particular setting(this doesn't necessarily mean you can't go back to the old bootloader-search for unbrick tutorial in development section)
2) from what i know they do(someone correct me if i'm wrong)
3)i don't know
4)i can assure you that official cm10 is an excellent rom and you should try it ) (i for one never had any major problems(bug call,bsod) and will return to it after some testing )
5) i think it will do just fine
6)every custom rom has some guiding points in the first post(and second and maybe third ) ) please do follow them and you will have no trouble.
good luck!

Thanks a million vader I'm going to give CM10 a shot on that note, but like you said if someone can confirm for sure if the H/W acceleration works that would be great too.

I don't think that h/w acceleration is something that lacks in the post-cm9 roms. After lg released both official ics, sources and our cm device maintainer aremcee(ricardo) got hold of them all stock roms and cm variants have hwa. I can confirm that tonyp, in his ParanoidAndroid has the option to assign which app to use hwa

Cool ok, Thanks again Just one last question - should I install kernels before/after zip if not specified by creator?I think I'm going to try pengus77's kernel and CM10 build for the new bootloader.

Flash the kernel after you're done with the rom. Cheers!

That was the last question hopefully Backing up my phone atm (done cwm, titanium and AIO backups, i should be covered ) and then I'm going to shoot this rom and kernel at it. I'll post back how it goes.

[Q] CyanogenMod on stock kernel

Hi!
I was wondering if it would be possible to run a CM userland on a stock kernel (Yes I am one of those fools who bought a device with "bootloader unlock allowed: no").
This has been done in the past for other phones and apart from delivering a CM experience to locked phones this would also allow for a working Bravia engine on CM. Sure there would be some limitations when running such a setup (e.g. because of certain kernel modules not being available), but Sony seems to update the official firmwares at a acceptable pace, so there are fairly recent official kernels available: Most recent stable CM is based on 4.2.2 as is Sony's most recent firmware.
I can hardly estimate how problematic other aspects (ABI version mismatches, etc..) might be when trying this, but I remember CyanoSpaceMod for the XU which worked for devices with locked bootloaders. It was a working CM9 and implemented CWM in the same manner as the dual recovery on the XZ for locked bootloaders running on the stock kernel.
All in all it seems to me that all the building blocks are there, but I have no experience in building CM, so I cannot do this on my own, I need some guidance.
Would it be enough to simply build CM for the prebuilt stock kernel as outlined here, even if it meant that tehre would be no CWM support initially? The kernel itself can easily be extracted from a stock rom...
Any help -- even just an educated guess -- would be appreciated.

Not possible matey.

Could you point me to somewhere, where I can find an elaboration on the subject so I can educate myself?
Why is the XZ so much different than other Sony phones? Or is it simply because Sony was so forthcoming in open sourcing everything they legally can, fostering kernel hacking so that the CM kernel now differs greatly from the stock kernel?
In that case I can fully understand that major changes in the CM base would be required to make it run on the stock kernel...
(I am actually just asking out of curiosity, since I got an unlockable device yesterday )

[Q] CM on locked bootloader?

I've read through the forums of the XZ, and found no trace of people trying to load CM on locked bootloaders.
So I was wondering if there is any development going into that direction on the XZ? (ramdisk hijack, kexec,..)
I don't have nearly enough experience to go into something like that, but I was wondering if something like this would be possible for our XZ.
Devs at Xperia SP forum managed to hijack ramdisk and load SlimKat and CM11/10.2 on a locked bootloader device, so maybe we can use the same method?
XSP thread
Maybe we can follow their example and get CM on our device working with locked bootloader!
Does anybody know any reason why this would/wouldn't work on our device? I'm starting to look into it, but maybe some more experienced developer can help.

I dont think its passible because CM need a custom kernel and the custom kenel need UNlocked bootloader

Roms like CM,AOKP,PA,slimkat and so on use custom kernels for their respective roms
Custom kernels require unlocked booloader, if you try to flash custom rom in locked boodloader it will get in to a boot loop
You will need to unlock the bootloader (which WILL void your phones warranty) then flash any custom rom

I am aware of all of the above. That's why I suggested hijacking ramdisk (as they did on Xperia SP). That would enable us to load CM (or any other AOSP based ROM) on top of the stock Sony kernel.
At least that's how I understood it. You can check the thread I linked in the first post. The devs even posted the links to the source code of the ramdisk hijack method!
