I have the stock kernel without root. And I buy my st15 since a week and I have a question because I'm confused.. When I flash a kernel that says " root and cwm" it mean that I have root permission to flash rooms? I don't need more?
Ahh.. Other question. With the rooted kernel in my phone I only need install the superuser to use apps that requires root access?
Excuse me for my bad English.. And thanks for your answers!
Since you are using stock kernel, u can use zergrush method to root.
but if u want to flash custom roms, u need to flash custom kernel. Almost all custom kernels are pre rooted and have clockwork mod. u need to unlock your bootloader to flash custom kernels.
the superuser app get installed by default when rooted.

ok. but my question is: I only need the bl unlocked and a kernel with cwm and root to flash a Rom? ( exactly the fxp cm9!)
You need to understand a couple of things about ROMs and Kernels.
Unlocked bootloader, lets your device get into "bootloader mode", giving you the privilege to install a custom made Kernel. Some kernels (most) come prerooted, which means that no matter what Rom you install, whether it is stock, or custom or whatnot.
Root gives you the ability to read, write, and execute apps and files that are in the /system folder.
Think of it as layers of a cake. Bootloader -> Kernel -> Rom -> Root

Not only /system folder, but everything else also, that is in / folder, that is the root folder. You get access to the root folder, folder before system.
thanks a lot! I go to do these steps with the fxp kernel for cm9!

According to me, CM9 already has root, right?

Rooted the phone using flashtool, then installed clockworkmod recovery using Xperia CWM-Auto. Flashed HYBROM 16, and then lost root access as well the recovery. Any Advice on how to get root acces back?
maybe u take a wrong step.
never heard such problem.
u should use custom kernel with root n cwm feature like rage kernel, x kernel, etc....
just try it again from beginning.

Hybrom requires custom kernel, like X Kernel, Rage Kernel or Kernel by bbooff.
These kernels already include Recovery also.
And that ROM already has root access.

Yup..u should install custom kernel..
My advice go for bbooff kernel if u want to install Hybrom..
to check whether u have root access or not just check the superuser app in ur phone..
I just now unlocked bootloader & now i want kernel with following features
1.Root
2.CWM
Every custom boot image has these
1. get custom kernel <--- you automatically got CWM
2. get custom firmware (ROM) <--- superuser included, usually pre-rooted

you don't understand dude... root is ROM related, not kernel. so stop struggling or i'll laugh at you switching kernel for the sake of root!!!
i guess mayb this will help. http://forum.xda-developers.com/showthread.php?t=1849802

as i said before, custom kernel doesnt bring you root, it just gives you CWM. to get root, you need to install custom ROM (coz custom ROM usually pre-rooted) or install root manually if you wanna stick to stock ROM. to install root manually, search this forum around.

What he is looking for probably call insecure boot image. There are basically 2 different ways to give root, 1) insecure boot image 2) su binary
1) Insecure boot image basically give root access to anything, which is why many rom developers do not use since AVERAGE user who dont understand a thing about their phone, this will bring lots lots of trouble
If you want this, compile it urself. Use google
2) SU binary basically manage the root privilege to be given to certain command or apps which u usually encounter.
Use custom rom or root it urself if you want to use stock rom. If you want stock with pre-rooted, put the su binary urself here or find some stock rom with pre-root

Hi, I have some noob questions about roms, kernels, etc.: 1)once I have unlocked the bootloader and flashed a custom kernel if I flash the stock rom with Flashtools I lose the root but not the bootloader unlocked, right? 2)once done this, for flashing a custom kernel with Flashtools I need root permission? I think no, right? 3)using Flashtools can I safely flash the stock rom with the exception for kernel.sin part? In this case the custom kernel remains at his place, right? 4)but in these cases I lose the root, and I have to do the rooting process again, right? 5)some custom kernels have auto root feature... with this feature manual rooting is not necessary?
Thanks a lot.

1) Yes flashing stock rom doesn't relocks ur bl.
2) Nopes all you need is an unlocked bl.
3) Neva tried
4) Nopes if you have unlocked bootloader just flash any pre-rooted kernel and ur good to go. Most of the kernels here are pre-rooted.
5) Nopes not necessary

Ok, thanks.
...but I have another question: 1)if after unlocking BL and flashing custom kernels it's not necessary to do rooting process anymore (in stock rom too...?) what is the auto root feature? I'm slightly confused... 2)are there then kernel not rooted? 3)then is rooting process about kernel and not rom part? Why do i read in every rom (not kernel) "Rom pre-rooted"?

After flashing a custom kernel... You phone will be rooted... So you don't need to ado any other rooting procedure then... Yes in stock ROM too
Auto root is just that all custom Kernels are pre rooted... You don't need to root separately...
The stock Kernel is not pre rooted
Rooting procedure is neither about ROM nor about Kernel... Its about Android OS... Root enables you to customize Android system...
Kernel and ROM are just its parts... Pre Rooted ROMs have superuser installed... But you must have CWM and Root to flash ROM.
And for more of such questions read the stickied basic guide.

...and if a kernel has not auto root feature? What does it mean...? like this one: http://forum.xda-developers.com/showthread.php?t=2160537 The developer has removed this function. Maybe I can ask in the developer thread directly...
You won't have root access... Simple... Stop confusing yourself.
PREDATOR95 ->->->->a.k.a. ->-> predatOr
Third question in first post.
No you won't lose root if u flash stock rom without the kernel. (provided u have a rooted kernel first)
For question 3... Yes you can... but if u want to really retain the kernel exclude fota and simlock too

I would like to run custom ROMs( CM) based in my device. To start with, I aj a total noob and my device currently runs stock ICS provided by sony itself. It's not rooted. I wanted to know the steps regarding how-to do the procedures like :
~> unlock bootloader ( is it needed or not)
~>root (needed or not)
~> flash custom ROM( which one is good and runs fast,least buggy)
~> which CM?
~> which recovery, which kernel, how-to's
Etc.
I don't know if all info is available on the forum in one thread or not, so I created a new thread.
Thanks in advance.
AW: Help regarding Sola Custom ROMs
You have to try every ROM on your own! Everybody has an other way to use it's Smartphone, so nobody can say which ROM is perfect for you and Root and CWM is needed for every Custom ROM Cause you need CWM to install the ROM and to install CWM you need Root And if the ROM is compatible with a locked or unlocked BL is said in every OP of a Custom ROM
Open your eyes and use the search function! You can find nearly EVERYTHING here on xda
But still a guide would be helpful...if possible...

If you don't wanna unlock your bootloader(which will void your warranty) but you wanna install cwm, you can always root your phone and install the cwm recovery... Now, every custom roms is very good!!! You must be thankful to all the devs here and try some roms on yourself... We can't tell that which Rom is good for you so you must try it on your own... CyanogenMod 9 is good and very smooth but requires you to unlock your bootloader... You also must unlock your bootloader to flash awesome kernels that provides overclock and many more...
You can find cwm recovery for locked bootloader at here!! Be sure to follow the steps properly!!
And to root stock .54, you must first flash the .10 kernel using flashtool, root it using binary method, then flash back the .54 kernel..
Hello
I have a few questions about the hole "thing" cause this is my first android phone and on apple there was just the option jailbreaked or not jailbreaked
My first question is about the bootloader.
since i was reading the thread "[FULL ROOT] Community RootKit! (ASEC vulnerability) {v01} [20140615]" i am asking me why should i unlock my bootloader when im able to get root without doing this?
Is there any special point for wich i need the unlocked bootloader or is it just written for the people who unlocked there bootloader already?
Then to second question is about the sequence.
Am i right when i
1. get root
2. install cwm or twrp
3. install custom rom?
by the way: is there any huge difference between twrp and cwm? because at the table "Kernels" there is the TWRP for the Xperia T2 Ultra and an unofficial version and from CMW is an unofficial version too? Wich should i use?
and my last question is should i wait for version 2 of the RootKit or are there just small differences?

Bootloader unlock is required to install Custom kernels like DOOMLORDS kernel. In case if you dont want that then no need to unlock BL.
Just follow this post http://forum.xda-developers.com/showthread.php?t=2784757 to get root on Locked Bl and then revert back to .402

hi manu44,
first thank you for the answer.
but it is possible to root and use an custom rom with an locked bootloader or?
is there a away to do it step per step?
i mean first root with rootkit, then later install an custom rom ? or do i need to do it all at one time ?

A custom ROM is different from a custom kernel. Some custom ROMs do not require custom kernels (because they use stock kernel), but others do. So it really depends on the custom ROM that you want to use. Instructions and requirements will be posted in the respective ROM thread.
But if you want to use a custom kernel, then you will need to unlock the bootloader first.
And obviously, if you want to flash a custom ROM that needs custom kernel, then you will have to unlock your bootloader first.
Even if you want to flash a custom ROM that does not require a custom kernel, you need to first root the phone with the RootKit. Because flashing custom ROMs is usually done via recovery, and recovery installation requires root.
Hope the above is not too confusing.

So just to be sure.
I Run the toolkit for root
Then i take twrp or cwm
And then i flash a custom Rom wich use stock kernel
And that can i do with a locked bootloader?
What can be different in an other kernel?

Yes, run Rootkit, install recovery (TWRP/CWM) and then you can flash custom ROM which uses stock kernel.
Custom kernels allow functions such as overclocking, undervolting, etc.

then i have 2 new questions
1. How can i downgrade my phone ? just download the fw and use flashtool?
got an iphone till now and there it was a hard work to do it ..
2. is there any difference between locked and uinlocked bootloader? i mean in the point of restoring so that i have my warranty back?
1. There's now an even easier way to root the 402 firmware that does not require you to downgrade first:
http://forum.xda-developers.com/showthread.php?t=2784900
But note this post, where you have to change something in the install.bat file for it to work on the Z2:
http://forum.xda-developers.com/showpost.php?p=53480221&postcount=81
2. It's a little more work if your bootloader is unlocked and you want to relock it before sending it to the service centre. You need to have your TA backup before doing so. If your bootloader is locked, you just have to remove root via SuperSU before sending it in for service.
