I heard there is a way to relock the bootloader by backing up a specific file or partition, but I forgot where I heard it..
Does anyone know more about this?
I have the 16GB Wifi version (SGP311) btw.
Are you talking about backing up the TA partition:

Just like title states. I was curious if they do for those that have forgotten or wasn't aware to back them up. I'm awaiting my z ultra today via UPS.
Thanks
AFAIK, DRM keys are contained in the TA partition, deeeep inside the memory. So roms got nothing to do with your drm keys. You will lose drm ONLY when you unlock the bootloader, and that's usually required if you decided to flash something that needs unlocked bootloader (e.g. most custom recovery and roms). If you by any means unlocked the bootloader, the only way to restore bootloader is by using backup of ta partition from the same phone.

Flashtool. But really if you are not comfortable with fastboot and adb please read more before you try messing with your phone

root and backup your TA partition now.
Then leave it unlocked.
Just flash what ever FTF you want. (any generic version will do)

unlocked bootloader wont make any difference from now on. No point in locking it unless you have a waranty claim.

Ta is a unique set of keys basically. It's static so remains the same no matter what rom, kernel or baseband you flash.

Well, it seems to me that Bell will never update the phone to KitKat, given that I never even got the update after .290, so I guess I have to take this to my own hands.
First off, is it safe to use flashtool on a locked bootloader? Sadly, Bell also screwed us out of an unlockable bootloader.
Secondly, will any ftf file that's for the 6833/6806 work?
And thirdly, what should I exclude via flashtool? My phone is currently on .290 with no root, a locked bootloader, and no way to unlock bootloader.
If anyone can provide any help, or even instructions to the procedure I should take, it would be greatly appreciated. Thank you!
Just flash the 6833 ftf and see what happens (all should be good.though) if anything goes wrong just flash a proper ftf for the bell version.

I never backed up my TA partition, is that something that I must do, or can I exclude TA from flashtool and have it work that way? I'm also unrooted, so I can't quite just back it up.

You only need to backup ta partition if youre unlocking the bootloader.
You shouldn't have any problems flashing a non bell ftf.

I flash ftf 6833 and my zu is 6802 . I nohave problem.:cyclops: my bootloder is lock!
+++++++++++++++++++++++++++++++++++++++
you must use The latest version FLASHTOOLS for flash ftf 6833 on 6802 Otherwise you cant flash !
youre fine flashing any c6833 .ftf i used the HK one, i just excluded baseband (since im not familiar with this stuff and i didnt want to mess with something that connects me to rogers lol ) TA is fine for us since our bootloader is locked from bell, i dont think well ever need to back it up.
Hi,
I had the S3 and switched to the Z2 last month. So I am new to the bootloader thing.
Is it right that I can relock the BL by restoring the TA partition for warranty for example?
Or can Sony see that I've unlocked it?
just be sure to backup your TA, and you can go back to your original undetectable state
.....
Hi thx for your reply
So when I restore the TA the BL becomes locked again? Or is it possible without locking it?
And do I need a new backup when I update from .402 to .314 ?

Why do you need unlock at all? Exist root methods without unlocking...
When I want to install a custom kernel for example.
Restoring the Trim Area locks the bootloader.

Does locking the BL wipes data the same as unlocking it?
Yeah m8, re-locking your bootloader will wipe your phone so, as always do a backup first:good:
I want to unlock the bootloader of my Z2 but I'm scared about relocking it with TA Backup. Has anyone tried it? If so, how did you do it?

what? i dont exactly understand, here is some info to clear up some doubts or potentialy answer your question. ;D
if you had a backup of your TA restoring it will relock your bootloader
relocking your bootloader doesnt bring the contents of your TA partition
and for me relocking i used flashtool as i do not have a backup of my TA partition
relocking or unlocking your bootloader wipes your device data so backup your internal storage before doing
