You can root and flash recovery without unlocking bootloader but the phone must be s-off.

I read in the Developers forums that you can get Cwm for Locked Bootloaders. Ive been trying to get it for a week and can this be done? I bought the Ultra at Bell and it says its model number c6806 and its locked.

Yes. here it is:

However just because you have CWM, doesn't mean you can flash ROM's.
All you can do is flash Root, and other mods.

sorry for the quick question, but would that work on the C6802 on .257, with locked bootloader? i've been wondering if i could get root without unlocking the bootloader(to preserve warranty).

yes you can root with a locked bootloader.
to unlock your bootloader you need to have root access.
You can always backup your TA partition, and then unlock bootloader, and then restore the TA partition and restore bootlock as well.
many possibilitites

hey thank you sir for the response. I got my phone with .257 version already on it tho, and from what I'm reading, I can't find a way to root on .257 without unlocking the boot loader. is this correct?
as I see it, the only option I have on .257 is to unlock the bootloader with the Sony method, but no way to root first. am I mistaken? thanks!

What you could do is use flash tool to go back to another firmware, then root, and then update to the newest version. But not flashing the kernel. then you can flash the modified kernel with CWM, and then flash the new kernel afterwards.
I think there is a tutorial on here that tells you how to do it.

ah yes, OK, that's what I was wondering, whether it is possible to downgrade the firmware with a locked boot loader, using Flashtool. perhaps I will try.. thanks
I just remember on some other devices I've had, a locked boot loader wouldn't allow a firmware downgrade.
I have unlocked the bootloader and now i found that there are ways to root to root phone without unlocking the bootloader is it possible to relock the bootloader without losing any phone capabilities.
If you've already unlocked there's absolutely no point in relocking it, you get more freedom and benefit more from an unlocked bootloader eg custom kernels and roms
i just want to know what is the way and suppose i want to give them for warranty repair so i should be prepared lol

If you used TA backup after rooting and BEFORE unlocking, you can return the phone to a fully LOCKED state as if you had never unlocked it.
If you didn't do a TA backup, you can only relock it and thus the reseller/repair centre know what you did.
i never made any TA backup it wasn't available that time there was no root that time without unlocking it.

Then you can't return to completely stock. The relocked notice will give you away.

Look at Xperiafirmware.com -> "Sony XPERIA Z2 D6503 - Android 4.4.2 - firmware 17.1.2.A.0.314". There is a solution to re-lock the bootloader.
Hey, i got Z2 1 week ago, and i want to unlock my bootloader so i can root and install recovery. Coming from other android phones i know the bennefits of rooting and installing a custom recovery, but what happens if i unlock my bootloader?
My bootloader is unlockable but what do i loose besides the warranty? I read in 1 thread that i can loose the quality of the camera. is that true?

You know you don't need to unlock your bootloader to root and install Cwm right? Also it is always advised to root, backup ta partition and then unlock bootloader. If you do that, you can restore your TA partition at a later date and recovery your drm keys.
Hi,
my phone is under warranty Feb 2016 should i unlock boot loader? it will void warranty i think?

There isn't much reason to unlock boot loader specially since root is available on all firmwares.
If you really want to unlock the bootloader for some reason then you can always backup your TA partition and then Unlock bootloader. Then if you ever get the need for warranty you can flash the original FTF restore the TA backup. You will have your warranty back.

Thanks mate will try to install now the official 5.0.2 from sony
unlocking your bootloader grants freedom and easier at loss of your warranty and some xperia features
however staying locked lets you keep your warranty and xperia features but its generally annoying for me atleast
It's possible to relock bootloader for Xperia X F5122 after unlock?
You can. But there's no way to recover DRM keys for now.

Relocked and Camera NOT Working... - Unlock, and it works.
Hi everyone, i have unlocked my Xperia X f5122 34.0.A.2.292 bootloader (Sadly)
after unlocking i noticed some functions like X-Reality not working anymore on my device...
i wanted to relock it again using flashtool, and i did it easily
but after relock camera will not work (camera app hangs when i press button or touch) - third party apps not working too.
when i unlock it again, i get camera working...
is there any way to relock bootloader and make camera work like when device is unlocked?
(sorry for bad english)

Don't know how to fix it but you could just flash this kernel:
http://forum.xda-developers.com/xperia-x/development/root-xperia-x-34-0-2-292-modified-t3449708
All functions like x-reality will work with this kernel
Relock then FLash? hmmm

Thank for Reply,
so you mean i have to relock bootloader then flash that kernel then unroot with super su?
can i get relocked boot loader and everything OK that way?
but for flashing that kernel i have to unlock boot loader
maybe this works? :
i unlock bootloader then flash kernel then unroot and then relock bootloader
but that way android ask me for patttern at srart which i dont know what is it so i have to draw wrong pattern 30 times to get device factory reset.
i dont know after than kernel will stay there or not.
its like 1 week im working on this device day and night

Problably not, you've unlocked your bootloader so your TA-partition is whiped meaning you lost your DRM keys. You can not get them back anymore. So without a kernel with DRM-fix you wont get functions like x-reality back. So just keep your bootloader unlocked and use a custom kernel with DRM-fix and you'll be fine.

Got a question, hope you can help me.
How close is that DRM-fix to the original DRM keys in terms of quality?

Is it possible to make the "bootloader is unlocked" message when booting up disappear?
No, only by relocking your bootloader.

Isn't Xperia XA came out on Android 6.01 ? if that so then you can use DirtyCow script to extract drm keys / TA.img.

you can block the bootlader now in android 8 and the camera is work
Hello: Someone can tell me if after opening it, the booloader can be blocked again. I have the DRM keys. I tried to do it by Flash Tool, but when I turn on the phone it always asks me for the android key and I do not know what it is.
Thank you.
I answer: Easy with oreo. An ftf of oreo is installed by flashtool and the mobile starts, we accept debug usb and developer mode. The mobile is turned off and reconnected to flashtool, given to the blu and relock option. When finished, disconnect the mobile and turn it on. Ask for Android key, well, it turns off and connects to xperia companion. The repair firmware option is given and the instructions are followed and when finished we have repaired oreo and the bootloader as before unlocking it.
Kisses, applause and thanks to all those who have helped me with the comments.
