I have brought my new Xperia Z1 (C6902) and I want to know about rooting it
Let's me ask
1. If I want to root my Z1 only and I won't need to install any custom rom, Do I need to unlocking the bootloader after rooting it?
2. If I only want to install an officially stock rom, Do I need to unlocking the bootloader?
3. If I want to unroot my Z1, How can I do?
Thanks in advanced and sorry for ym English
1) No.
2) No.
3) Flash Stock Rom.

Thank you very much. I've waiting for this
For one last question,
To flash the stock rom without unlocking bootloader I must flash stock rom with Sony Emma , PC Companion or another flash tools?

Somewhere I read on XDA that we need to Lock the BL before flashing the Stock FTF?? :silly: Is it true?
I never did this with my arc... Many times I flashed the stock ftf without locking the BL everytime..

With locked BL, u can use pc companion only to restore the phone to stock Rom.
With unlocked BL, u can use flash tool only to flash ftf files.

Right.. Once we unlock bootloader and try to get any OTA or update via PC Companion/SUS, we'll end up bricking ur phone.. So in this case, we need to Relock the BL. But to flash an FTF via flashtool, we need not relock the BL. Just wanted to refresh my knowledge after reading that post...
Flashtool can be used for locked and unlocked bootloader.

Hi there!
I've unlocked using flashtool, installed CWM Recovery and rooted using the recovery-only root.
Now, I need to return the phone to as stock as possible - certainly removing root, but relocking the bootloader would be a good secondary objective.
My current plan is to use the flashtool to relock the bootloader, then use the PC software to repair the phone. Will this work?
Thanks for your help
Edit: I've searched the forums but can't find an answer, including in the starting thread - please link to a relevant portion instead of the whole thing if possible
Further edit: There's no 'relock' option in the flashtool - huh?

As of now there is no option to relock the bootloader. You can unroot the phone by simply performing a repair system command in Sony PC Companion or flashing a stock rom. This has been explained in every single rooting or custom MOD thread.
Ya you are right. Relock bootloader using flashtool and repair or flash a ftf from flashtool.
And IIRC in the beta version of flashtool u will find option to relock under BLU. And btw u won't get back DRM keys and no Bravia engine.

I don't see the option to relock anywhere - perhaps as I did the unlock on another PC?
If you can't get it to work with PC Companion use SUS (Sony Update Service which you can download from Sony's website) http://www.sonymobile.com/gb/tools/update-service/ --> for UK

You have to relock the bootloader with flashtool beta4,click on BLU.
Flash a stock rom and repair it by update service.

Thanks - I expected there to be a separate button for relocking - whoops!
I've flashed the stock ROM and that's gotten rid of the root. It also says that the bootloader can be unlocked, so that seems all perfect as far as I'm concerned. Thanks for your help, ladies and gentlemen.
Hey guys I have a rooted Xperia Sp(C5302). We know that our device is gonna get the 4.3 official update next month. My question is can we update to the official 4.3 even after having root or will it cause a problem.

As said above, root is no problem with PC Companion.
However, if you unlock the bootloader, no update whatsoever (PC Comp, OTA). After bootloader unlock only Flashtool /Emma will let you flash new ROM/updates.

Hi , so if i Relock the boot loader i will be able to use ota rite?
which is the safest method to Reload the Boot loader
I am using BL Unlocked Rooted Stock Rom ,
I think Sony stated on their unlock website that once you unlock the boot loader there's no way to relock. Check out unlockbootloader.sonymobile.com

If you backed up your DRM keys with TA-backup you should be able to relock if you didn't you are kinda screwed

You will always lose signal when flashing back down to 534, you will get it back when you upgrade

rue, I did not notice he said that
OP, you should just flash a 757 FTF then a custom kernel.
Bang, you have root!
1stly i have 4.4.2 (.757) running on my z1 and i downgraded to .534 and i rooted the device by vroot and backed up the DRM keys successfully.. and then i flashed to .290 and unlocked the bootloader by flashtool and then downgraded to .534 and then installed the dual recovery and then flashed using the flashable recovery using recovery and then i found that camera is not working properly.. camera is opening and when i press the shutter butter its trying to focus the area and after focusing it freezes and doesn't shutter... so this is my problem... please help...
So much fail.
Do not use vroot, it sends your imei number to an ip address in China.
Also, unlocking your bootloader on 4.2 will break your camera, it clearly says so on the Sony official site about unlocking your bootloader.
Now, the solution.
Restore your ta partition.
Use pccompanion to update to the latest firmware
Unlock your bootloader again
Flash a custom kernel of your choice
Install super user app of your choice

.534 is 4.2 FW. the camera will not work with an unlocked boot.

yeah..!! i have done it.. thanks
but i have unlocked it in 4.3 does it make any sence by unlocking the bootloader in 4.3 and i didn't get any recovery mode... so.. i downgrader to 4.2 and installed the dual recovery as the thread says it needs .534 firmware to root properly...

I have to ask
Why are you unlocking your bootloader? What have you done it for? You do not get a recovery mode just by unlocking the boot, you have to flash a custom kernel with recovery in it
You either do all the downgrading and install dual recovery if you have a locked bootloader
OR
You unlock your bootloader, flash a custom kernel with recovery and install super user app
there is no need for both approaches and that's why you are getting problems

i unlocked the bootloader... i didn't find any recovery after unlocking so i followed the xzdual recovery process... but is it safe to flash a custom kernel.. and by installing only recovery without kernel does this doesn't help..

Why did you unlock the bootloader? What did you want to do with it?
You can not install a recovery without a custom kernel, xperia devices have no recovery partition, it can only be installed by pushing the ramdisks to the system partition or by flashing a custom kernel.
Please follow the advice I gave several posts ago.... that is your solution.
Then spend some time reading up on xperia device flashing.
1) Xperia devices have no factory recovery or recovery partition
2) Unlocking the bootloader is the fastest and easiest method to root and get recovery (If you are allowed to do it)
3) If you cannot or do not want to unlock the bootloader, then go through the downgrade, root, dual recovery process...

Greg said fifteen times - follow his guide for here.
Yoy can't flash custom kernel especially not fastboot custom kernel on locked bootloader.
Whole purpose of unlocking bootloader is to flash custom kernel.
You are confused with all this informations, I would recommend that you read few things here on XDA to understand terms and other things.
You could seriously damage your device with just one wrong step.
