Xperia S Rooting question - Sony Xperia P, U, Sola, Go

Hi, i want to root my Xperia S. So ive read all the tuts and other threads.
So first question is: I have build-number 6.1.A.0.452 (ICS), can i root it without downgrading to GB?
Second question: Can i unlock the bootloader without downgrading (in the tuts its written about GB) ?
And last question: Do i have to unlock the bootloader to have root?
Sorry if this had been answered before, but the XS section is totally new to me. I had a HTC Desire totally modded before so this is totally different now thats why i'm asking.
Thanks in advance

1) If your bootloader is unlockable
2) If your bootloader is unlockable
3) No, you can root without unlocking, but you'll need to downgrade.

Yes, my bootloader is unlockable (i forgot to write that)

There is a way without downgrade. Unlock bootloader (ALL DATA WILL BE WIPED INCLUDING SDCARD), then flash Advanced Stock Kernel by Arakmar. Reboot and voila.

I think, you have locked boot loader & stock kernel ?
and that rom required unlocked boot loader & V3 kernel !

i have just bought new phone don't want to loose warranty as early as possible may be later i may dare to unlock it
i love developers who makes world look better place.. i am frequent visitor of xda from my first windows mobile since 3-4years ..
but i had very bad experience with z71 android handset which gave me lot of pain but i made full use of warranty period because there was no unlocking ..! just flashing lots of custom roms ..
but xperia is different i think i have to gain more confidence to start flashing.. because there will be no warranty once unlocked...
When you feel confident, you can Unlock you device by any method you prefer, follow the guide by following link,
http://forum.xda-developers.com/showthread.php?t=1409269
P.S, using official method to unlock the boot loader, you will void your warranty, but using XDA method you will have option to relock the boot loader again
Hope, this will help

you're welcome,
that means you are qualify to unlock your boot loader,
its not Pre-Unlocked !
if it shows No, that means you cannot unlock boot loader due to Manufacturer restrictions.
invoices presone
my phone is already rooted can i oerclock by setcpu without unlocking or do sommething etc
I think, overclocking need other then stock Kernel, check Kernels thread, which suit your overclocking need.

It allows you to put custom roms and custom kernels. It also voids your warranty.
If you phone is sim/network locked (in service menu it'll say something like: "Bootloader unlock allowed: No"), then you cant unlock bootloader unless you pay someone to unlock it with network unlock codes. Afterwards you can unlock it via offical (SE) or test-point method.
yes. subforums you try to check on development. there are many tutorials to unlock and root

Yes it is worth unlocking the bootloader. With an unlocked bootloader you can do almost anything with your phone.

Well that depends, it might have been worth for you, but for someone who likes stock rom and has no need or will to change it with custom rom (except few tweeks that can be done with root), it's probably best to keep it locked. I look at it as a pretty subjective thing. If losing warranty is not an issue and you want to go that extra mile, sure, unlock it.

[Help] Re-lock Boot-loader | Xperia Ray.

Hello!
My ray's bootloader is unlocked via testpoint method and now i want to re-lock it as i need to give it to service center for softkey repair.
Is it possible?
Thanks. :fingers-crossed:
first google before posting here man, if you unlocked bootloader via offical method there is a way to unlock it but if you unlocked it using testpoint method the bootloader unlock allowed says yes so technically according to sony your bootloader is locked so there is no method to relock it if you unlocked it with this method
Hope i helped

Sorry brother i searched a lot but just found a way to relock it if you unlocked it via official method, so i made a thread.
I will ask to delete it as soon as i get the answer.
So should i give it to service center just after flashing the stock rom & kernel?
You sure there is no way to re-lock..
I'm afraid as why the RESTORE button is there in s1tool?
actually it's quite conflicting dude anyways check these threads out

[Q] Not possible to unlock phone - is there anyother method to do it?

Hi!
I've got a problem with unlocking my XPERIA U. It has Orange branded firmware, Android 2.3.7, and I'd like to change it to for example ICS. I wanted to unlock my bootloader, but I can see a message: Bootloader unlock allowed: No.
Is there any possibility to unlock it, or not? And why this phone has no possibility to do it?
Regards,
linoskoczek
Unlock = debrand? If yes, just flash stock ROM 1.54 or 1.75 with flashtool.
You can make branded ftf backup before flashing, just in case.
BTW why do u want to unlock bootloader?
Odp: [Q] Not possible to unlock phone - is there anyother method to do it?
No, you can't unlock your phone. Probably you have simlock and locked bl by operator(Orange). But you can flash fw without Orange apps etc. Just go to development section and download latest ICS fw.

Ahh that ****ty orange...
I've flashed it to ICS, but still unlocking is not possible. Anyway, do you think http://forum.xda-developers.com/showthread.php?t=1886460 will root the phone? It's just a one thing I can do without unlocking xperia.

I think the only thing you can't do in SXP with locked bootloader is flashing custom kernel. So, the answer is yes, you can root the phone without unlocking bootloader as well as e.g. install CWM recovery.

If you want to install a kernel like lupus, first you need to unlock your bootloader. Use this tool to unlock it.

The risk of brick your device, but a lot of people already unlocked their bootloaders without any problems, your DRM will be permanently deleted, but believe me you can get more from your phone when the bootloader is unlocked, really worth it.

And you loose your warranty
Drm won't be lost if you unlock using testpoint method.

First check the bootloader status.whether its unlocked or not.
If its already unlocked then you can flash any custom kernel.If not you have to unlock BL first.Its not harmful but it will avoid your phone warranty.Try to use SE web site to unlock BL.Its the safest way..
After unlocking BT u can flash kernels anytime using Flash tool™..
Re:How to install a kernel
To install a custom kernel,you have to unlock your bootloader and there are two ways of doing it:
1.Use the official sony method...
head to unlockbootloader.sonymobile.com and follow the procedure there..
by doing so you lose your DRM keys which means services like track id wont work anymore...
2.use a testpoint method which is a bit complicated but you retain your DRM keys
for the testpoint method check this out
http://forum.xda-developers.com/showthread.php?t=1730874
Bootloader unlocking should be done carefully,you might brick your phone if you are not careful..
after the unlock is complete you can use flashtool to flash a custom kernel in fastboot mode..
