you can not. sonys answer:

If you update using any method that isn't a manual flash, be prepared to brick the phone. Re-locking the bootloader is possible.
Just make a backup with Backup-TA (LINK), flash custom rom and if you will come back to stock updated rom just flash stock ftf with flashtool and restore loader

Hey guys so to update to JB I relocked my bootloader and update using SUS. Everything worked fine and i was running JB.
Later I tried to unlock bootloader using Sony's official website. The bootloader was unlocked but I was stuck on the boot animation and it refused to turn on even after 30 minutes!
So now I have again relocked bootloader and repaired using SUS but i want to unlock on bootloader on JB..
Has any one tried unlocking bootloader on JB?
I tried unlocking BL on XGO, and it was giving me errors too.. Can't unlock it and I'm searching for an answer.
Anybody else can confirm that BL can't be unlocked on JB?
I wast just thinking of this because of root but now I'm unsure
I just unlocked my bootloader on JB, and after that I faced the same problem - It got stuck at bootanimation!

Why would you relock your bootloader anyway? Why not just flash a .ftf file using Flashtool?
Isnt it completely useless to relock your bootloader when you will unlock it again later??? i dont get it :silly:
after jb update my bootloader unlock status changed from yes to no,
I am unable to unlock it now, it's their any method to unlock it.

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:
http://forum.xda-developers.com/showthread.php?t=2426739
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 am cureently on .532(downgraded to root and backup TA). The thing is I can't apply the OTA. I also tried to temporary unroot the device. I also didn't mess up with any of the system files. The only thing I did after flashing .532 was rooting. Although the update via pc works fine but I want to keep the root.
Thanks

READ THE STICKIES
that said... now that you have backed up the TA the best thing to do is unlock the bootloader, then upgrade to .290 or .136 and flash recovery/kernel and re-root from recovery by flashing SuperSu

Is your bootloader unlocked if it is you have to lock it to apply ota the ota will download fine but you can't apply it unless you are on locked bootloader and if you are on locked bootloader you have to download root keeper app backup root reflash the .532 ftf or .290 whatever version you like the ota will apply just fine the download the app again and restore root.................

I did flash .290 and tried to root it after unlocking the bootloaded but I got stuck in bootloop. So, I went backup to the other .540 again to root it for meantime.

To get root on .290 with a locked bootloader follow this guide once you have .532 rooted:
http://forum.xda-developers.com/showthread.php?t=2612980
Then follow this guide to update to .136 (the latest FW):

Hi,
As we all know unless we downgrade and stuff, or install custom recoveries (which require some hackeries) we can't root the latest firmware.
I came across this method: http://whiteboard.ping.se/Android/Rooting
It uses the original boot.img and edits it then using fastboot it flashes it with the su binaries and security turned off.
Would this work on our Xperia?
Thanks
Probably, but you'd need to unlock your bootloader...
That kind of defeats the purpose. I'm trying to not do that
I want to be able to install OTA updates and support.
You can alway relock back once rooted. By that, you can OTA update safely and keep rooting

Ok so if I follow that guide to get root, unlock bootloader, flash the new boot, and relock bootloader, I will be able to install OTA?
Won't that brick my device since I have a modified boot.img?
In order to relock the bootloader you must firdt change back to a stock kernel, otherwise you will brick the phone, wich luckily is recoverable...
Even if yo relock on custom kernel, you will also can enter in fastboot mode to flash stock one

Basically the title. Is there a difference?
Also, I have a RN3P-Kate. I'm seeing there are a few methods to root and install TWRP. Which is the easiest/safest/best way?
No, it's not the same thing.
They are all pretty much the same, you need to have an unlocked bootloader (request from xiaomi), then you go to fastboot mode, install TWRP through fastboot, and then you can flash supersu to root.

Will I still receive OTA updates if I root, or will I have to manually update (via flashing) and reroot again?

I'm getting some conflicting information about this. According to some people on reddit, if I use Global Dev for example, I would need to unlock the bootloader to change from Global Stable to Dev, and then Dev would offer OTA (maintaining bootloader unlocked, i.e. staying rooted), or am I misunderstanding this?
