Stock ROM kernel??? - Sony Xperia Z Ultra

Just for those like me. The ones that want to stay on stock Xperia ROM but benefit from custom kernels.
So at this time there is no need or reason to unlock bootloader if you want to use stock Xperia ROM and flash custom kernel, since there are close to or just none for the current stock ROM. For older versions there is one...doom kernel, but seems like that one will most likely stay withot support...
So for stock don't bother

Why are the Gingerbread ROMS not Flashable through CWM

Sorry for asking this,
But
Why are the Gingerbread ROMS not Flashable through CWM, What is the requisite exactly, while i am able to flash Froyo roms which uses official sources. why is this not possible for Gingerbread.
And Also Can the GB ROMS include the new basebands with them, so that the need for flashing baseband separately can be avoided.
thanks
They are, except for the stock ones and ROMs based upon it.
No, there is no known way to flash baseband from recovery.

[Q] Which kernel for stock ROM (ST15i)?

which kernel should be used for the stock .62 firmware. I dont want stock kernel since i want root and cwm
(bootloader unlocked via official method by sony)
try this one:
http://forum.xda-developers.com/showthread.php?t=1440161
or this one if you want to overclock:
http://forum.xda-developers.com/showthread.php?t=1398910
its probably the most stable kernel for beginners
Rage kernel recomended.I use this one since i got my mini, that is 3 months and so far absolutely no problem.
Rage Kernel or X Kernel, last one requires also custom WLAN modules, which are also in the topic. Both have worked fine for me, your own choice, which one you want. Didn't notice any difference in battery consumption between these two kernels.
thnx everyone. pls tell me the order of installation of kernal and rom. which one should i install first? and do i need both .42(for rooting) and .62(for upgrading)
First kernel, then ROM.

[Q] Baseband

do i need to manually update the baseband of my phone? or each kernel/ROM has differrent baseband? help me plz
if a different baseband is required for a certain rom then this will usually be posted on the first page..
just check requirements of the custom rom first.
custom kernels - official ftfs
i just wanted to know if there're any risks of flashing ftfs while using a custom kernel. for example, i installed a custom kernel (Rage something) which only supports stock ROMs. i have a LWW which had .62 baseband. i downgraded it to .42 for rooting and all that. now, will my phone get bricked or something if i flash a different ftf, official or otherwise? (for instance, like the one in this thread: http://forum.xda-developers.com/showthread.php?t=1605150) the thread has .70 baseband, but as far as i know, latest officially released by SE is .62, so is this a custom one? also, how do i root .62? i have already unlocked the bootloader.
also, if it's not too much trouble, can u pls explain the architecture? as far as i can understand, Kernel and ROM are parts of the OS, rite? so what's the baseband (firmware), considering these are all software components?
just checked the link that you have posted. this is the ported official ICS rom.
that rom has its own kernel.
flashing it to your current kernel would brick the phone.
also there will be big differences because you currently have GB (Gingerbread).
baseband is the radio firmware, that is for the phone signal. this will be region dependent.
so, the baseband is the ftf thing, rite? but ppl were saying that .58 (in LWW) had some bugs like repeated rebooting of the phone, and that .62 fixed this bug and also improves battery life.
also, i repeatedly flashed many kernels into my phone. i mean, every time i tried a new ROM, i had to install the kernel provided with it (like FXP 115, or the one provided with the rom, the boot.img), over the already existing kernel, but i had no problems. so when does the risk of bricking come into play? i couldnt really understand what u meant by, "that rom has its own kernel. flashing it to your current kernel would brick the phone."
and yeah, i tried some ICS roms, like these:

http://forum.xda-developers.com/showthread.php?t=1445821 (FXP 115)
CM 7.2 RC0 coconut
each had its own problems, so i reverted back to stock. but gotta admit, the CM9 android 4.0 UI was really awesome compared to GB
when i was using .58fw, did not encounter the automatic restart.
never noticed that much difference also after upgrading to .62
this is the build or sw version of the rom.
the baseband is independent from this build of the rom.
you are doing it correctly, flashing the required kernel for each rom.
if you would just flash new rom over any kernel would result to bootloops.
bricking is really minimal and there are still ways to fix it,
it is rare that changing roms and kernel causes permanent brick unless there was already a hardware problem to begin with.
im also checked this roms but haven't installed them yet.
will stick with hybrom for now,

Custom ROMs for locked bootloader/stock kernel

Hi!
I would like to ask whether there are some really nice custom ROMs for locked bootloader / stock kernel. (Yes, I really don't want to void my warranty.) If anyone knows one, please share a link here. Thanks!
If you really want a custom rom without unlocking bootloader and for stock kernel :
Ask SONY to make one for you because ONLY SONY/official firmware can be install for locked bootloader or firmware that are sign by SONY (mean custom firmware that SONY certificate only)
If you really want custom rom badly,why don't sacrifice your warranty for something that you like?
Custom ROM removes your warranty also.
You could try THIS one... it's a mod, not a custom ROM. This is the best you can get without unlocking the bootloader.

[Q] Do custom roms have kernels? Like CM12

I have never installed a custom rom in my 4 year android experience. But alwaya modified stock roms. Now I have gotten tired of the stock lollipop performance on my note 3 n900. A nexus 5 is way faster than my note 3.
I am thinking about flashing CM12.1 on my note 3.
But I am scared about kernel stuff.
Do custom roms replace the stock kernel? Like CM12.1
And is it dangerous to install custom kernels.
Also
How easy it is to go to stock after custom rom?
Is it just a simple flash through odin?
I read somewhere that odin mode can also get corrupted.
I want to know
How easy it is to mess up the odin mode and Brick my device 100 percent
As far as my knowledge goes
As long as there is odin
U can flash stock rom.
Plssssss do give answers any one who is advanced in android at such a level.
It wud mean a looooot to me.
