what is the difference between rom & kernel flashing ? Are they interdependent (eg flashing a custom rom requires custom kernel beforehand or vice versa) ? what difference do they make by flasing custom rom & kernel ? Do they depend on odexed or deodexed rom ?
Flashing kernel requires cwm/ flashtool with unlocked bootloader.Do flashing rom also requires same ?
I need to clarify these things befre flashing rom * kernel.Also which is the best one till date for custom rm & kernel?
XL C2104, 15.3.A.1.14, Odexed stock rom with locked bootloader & full root.
should i flash a custom kernel before any custom rom ?
should i get ubl & deodexed rom 1st ... ?
ROM's are majorly Deadened.. They consist of some moded features from different phone or version of Android.. They can be modified as required..
Kernel's consist of CPU & GPU governors, schedulers, CPU linking, CPU & GPU overclocking, etc..
You can flash a rom without unlocking your bootloader, but you cannot flash a kernel without unlocking the bootloader..

if u unlocked ur bootloader u will lose ur warranty......so u must make TA backup before unlocking ur bootloaders....after that u can flash kernel with CWM or TWRP RECOVERY from where u can easily flash custom rom .zip files.......HOPE THIS INFO HELPS...

hey i'm coming from using moto milestone n i'm really confused abt something
since there was no custom kernal for milestone
1) when i root my phone do i unlock the bootloader also ?
2) when i install a rom which says it has a kernal so tht means when i flash it the custom kernal flashes as well on its own ?
3) if i install a rom n then i want another kernal, do i flash it the same way ?
1. Bootloader need to be unlocked in order to root and install custom roms.
2. Each rom comes with a kernel but you can flash other kernels on it.
3. Flashing a new rom will wipe your kernel to a stock one which comes with the rom. But you can reflash any kernel on it.
So basically unlock bootloader> root> install clockworkmod> make backup> install rom> flash kernel> install different rom> reflash favorite kernel again.
When I install a custom Rom which works with custom Kernel do I install the kernel automatically too? Or I need to manual install the kernel?
Normally the kernel is included in the ROM. If not flash it manually
The kernel will be included in the rom you flash. Whether or not its a custom or stock kernel is down to the developers preference. If the kernel included is not to your liking you can flash a different one.
Thank you!

you will better off asking in the forum speecifically for that device.
try here

custom rom
I'm not responsible for any kind of damage to your device.
the following steps will do
1. search the forum for suitable device (sony lww wt19i in your case), see if there are some rooting methods available..
once you root the device go to play store or market and find app named "Rom Manager".
2. install rom manager when prompted install clockworks mod recovery make sure you have open wifi access in your reach.
3. once done look for suitable rom in the forum or google it .
4. do read comments regarding the custom rom .
5. place the downloaded rom into your phones memory.
6. if you are ready for the risks restart into recovery mod and install the rom .

This device is not supported by Rom manager and clockworks.
For sony devices you need to read the device forum (As i stated above) and use flashtool to root (And flash stock ftf's) and to flash custom (Stock based) roms you need a CMW based recovery (A dev will have made one in that device forum I presume).
Furthermore, to flash custom kernel you will need an unlocked bootloader.
Sony only have official bootloader unlocking for some 2011/12 devices, so it may only be possible on this device if a dev has found an unnoficial way
very true

yes this is true about sony devices,..
not much of a grip on sony stuff
1 lets say if I m on kitkat kernal and kitkat rom! Then I wanna revert back to jellybean do I need to flash jb kernal first from recovery then rom ?
2 if I flash Custom kernal and rom some hardware issue arrise obviously I need to be on stock rom and stock kernal and locked bootloader! So I tried finding stock kernal for Xperia L but I failed? How to get stock kernal? Or I don't need it I can fool Sony by installing stock rom only?
Grab the ftf from the link
If you want to revert back to JB:
1. Flash the kernel using flashtool.
2. From the recovery, you can install custom Rom.
OR
If you want go back to stock, just the flash the recquired FTF

i am not overly familiar with many things regarding different kernels and how to work with them, so i was wishing a few questions that i had could be clarified by someone who knows:
1. when a kernel is flashed? i mean except for the times when we flash kernel.zips via recovery, is it flashed whenever we install a custom rom? or is it flashed with bootloaders when we flash firmware?
2. I am using CM12 official nightly and facing camera frizz issues. I came across a post in the official CM12 thread where they said flashing a modified kernel supposedly fixed this problem. Now my question is, after flashing a custom kernel, is there any way to go back to the stock one? by stock i mean either the one i was on right before flashing the custom kernel or stock moto g kernel provided by motorola?
that also begets the question, can kernels be backed up like roms using recovery?

1. The kernel is first flashed when you install a ROM. You are supposed to flash a custom kernel after flashing a ROM otherwise the rom zip will overwrite it. It doesn't matter if you install it in the recovery or the boot loader.
2. To go back to the stock kernel just take it from the zip of the ROM and flash in the bootloader
where can i find the kernel inside the rom zip?
and if i want the stock motorola kernel that comes with factory firmwares
how can i collect that?
A ROM.zip contains the system folder and a boot.img
The kernel is in the boot.img
So if u flash a different kernel and still facing problems then flash the ROM again.

flashing only the boot.img of a rom wont bring back the default kernel?
and is there any way to make a flashable zip of a kernel from that particualr boot.img?cause all the kernels i see (like donkey kang/customized cm12 kernel) there are all distributed in .zip format.....
