But i have a locked bootloader
Please tell me how to do this
And if i have to unlock the bootloader
How to, without sony knowing.....
u can't...
the only way is to make a backup of your TA partition, unlock your bootloader, and flash a custom kernel. then if you need to send it back for warranty just flash the stock kernel, restore your TA partition and it will be as tho your bootloader was never unlocked
Re-lock BL

Is that really that easy ? As far as I remember relocking other devices (sola) needed more tinkering to do that.
Hi guys,
I loaded my brand new xperia sp with root and cwm on a locked bootloader but now i want to try out CM but from what i understand is that you need an unlocked bootloader, so my question is if i backup my TA partition and unlock my bootloader, then flash cm with it's kernel and would it be possible to reflash the TA partition and relock the bootloader while on CM?
thanks,

No
You can only restore your TA partition and relock the bootloader on the original Sony kernel, if you try to do otherwise you may hard brick your phone.

That.. But you could figure this out by reading the tutorial of DoomLord
All the steps for unlocking and relocking the bootloader are described there
Hi everyone!
After searching for rooting newest firmware of 12.1.A.0.266 with LB, I found that it may be impossible without unlocking my BL. So I decided to unlock BL & root it via DooMLord's method and relock again. But I have a few questions.
I heard it's important to backup my TA partition before unlocking so I do a search for it. So I found that root permission is needed for backup TA. Since firmware 12.1.A.0.266 cannot be rooted, I have to downgrade to Android 4.1 and root it by DooMLord's method. It's all OK for me.
But I need to know, if I do restore my TA backup that taken while running Android 4.1, on my newest firmware 12.1.A.0.266, can it be conflicted that lasting bootloop or bricking my device? And relocking my device will it definitely lock my BL to factory status? Please be kind to help me with these questions. :good:
Thank you all :laugh:

No restoring TA wont cause bootloop but to be extra sure you can first flash 4.1.2 restore TA and flash 4.3..

My friend,
Thanks for helping me! :good:
If I restore TA mean I'm relocking my BL. So if I flashed 4.3 again I cannot gain root access coz it cannot root without unlocked BL. Am I correct?
So how can I root 4.3, if I flash 4.3 over 4.1.2 as root is lost after flashing a new firmware.
Thank & Regards! :good:
You need to root on 4.1.2, install CWM. Download and flash a 4.3 ROM and last flash 2.266 kernel
But there are proper threads for this xD

Yes brother..... I see several threads that explaining how to do that. But I wanted to root official firmware by unlocking BL.
If I restore TA, should I relock BL after that or, first relock BL then restore TA?
Thanks!

To make it easy, unlock using flashtool. It'll automatically make a TA backup. Later when you're done flashing stock kernel you can easily click relock and it'll restore TA and relock it for you as easy as 123.

Bro,
Is that unlocking BL via Flashtool exactly same as unlocking via official Sony method? If I unlocked BL besides official method, can I relock it again successfully? And so, since official method needs to device connected with Fastboot mode, but Flachtool needs device connected via Flashmode to Unlock/Relock BL. Why is the different with this methods? Pls kindly explain this......
Thanks! :good:

Yess absolutely the same. I'm not sure about relocking it after using the official method but I think restoring the TA key actually means relocking it. Well actually you will need to fastboot on flashtool right after the flashmode. There is no difference in result. It's just an alternative way to unlock and relock. Unlocking using official Sony method is the old way of unlocking. Flashtool is just to make it easier and simpler. The result will be the same. But be sure that you make the TA backup before unlocking it for the worst case scenario not to be able to relock it

ROOTED Locked bootloader
If I received unlock code from Sony, unlocked phone via official way, than relocked bootloader and restored TA is there any way that service will detect if bootloader is relocked?

I think sony is only able to see especially if your request code!! but the operator does not see it because he lacks experience lool he does not know the word bootloader!
why this issue ??

I dont't think so, because you can request the code and never use it. Restoring TA brings the phone back to state like it was never unlocked. Nobody can tell if you unlocked bootloader or not. If you relock bootloader via flashtool instead via restoring TA backup, then they can tell you relocked it because your DRM keys will be missing. You are safe.
merci

But if I did these steps:
1 Relock bootloader via flashtool
2 Repair via PC Companion
3 Install root and restore TA Partition
4 Install official firmware from here: http://forum.xda-developers.com/xperia-z/general/stock-xperia-z-c6603-10-5-0-230-central-t2759584
Is there ANY chance they will detect it?

No is the simple answer.
I don't know if they have the tools to check such things, but they most probably will only check if official fw == 1 &if bootloader lcoked == 1.
I normal language: They will only check if you have official fw and if your bootloader is locked.
ok
is it normal that the "TA backup" is 160 kilobytes? i did a backup sometime ago.. but 160kb is not really much.. i thought it would be 800mb or something

Yes, it's normal. My own backput weight is only 121KB.
I have TA backup and locked bootloader.
If I unlock and thereby delete the TA partition, can I then restore the TA partition and still have working DRM functions while keeping the unlocked bootloader ?
No, if you restore TA partition, the bootlloader gets locked again!
Sadly like ulysse34 said

There is no way of keeping an unlocked bootloader with DRM keys active
I unlocked the bootloader, is there any way to restore drm Keys?

You can Re-Lock your device first (just to be safe)
If you used FlashTool to unlock, simply click the unlock bootloader option and make sure the IMEI and unlock code are the same and click Re-Lock
If you did it the Sony way, you should be able to use flash tool
To get back your DRM keys simply go into the TA-Backup program http://forum.xda-developers.com/showthread.php?t=2292598 (script thing) and click on 'Restore'
If you did not make a backup of your TA keys... I am sorry... but you have no way of getting them back

Good News, you can have an unlocked bootloader with DRM functions http://forum.xda-developers.com/crossdevice-dev/sony/xperia-z1-z2-z3-series-devices-drm-t2930672
This thread should help you out, you can have an unlocked bootloader with recovery / root and keep the low light etc functions
