Unlock is Unlock bootloader or unlocked to work with all sim?
If you have unlocked bootloader just do it next step:
If you want to flash it with Flashtool, you don't need to lock your bootloader.
If you ask for update with Pc Companion or Update Service, furst lock your bootloader and then try.

[Q] Xperia Z1 root problem. Please help

Hello dear members,
my xperia Z1 is running on 4.4.4 build 14.4.A.0.108, I was looking for a method to root it.
I understood that I have to unlock the bootloader before rooting. The problem is that the phone says bootloader unlock says NO when i enter the "*#*#7378423#*#*" menu...
Is there a solution to root the phone without unlocking the bootloader or a method to unlock the bootloader even if not allowed?
Thank youuuuuuu all
You do NOT have to unlock the bootloader to root
You do HAVE to look in the development section for the root tools though
Just google "root xperia Z1 4.4.4"
Thanksss !

[Q] Z1 cyanogen 12 (lollipop) on Xperia Z1 bootloader allowed: No ?

Hi XDA!
I just did a straight 7 hours research on how to install cyanogen rom on Xperia Z1, then i saw that we can't on smartphone that is not allowed in the bootloader.
But i saw that we can install with some roms ready for bootloader not allowed. but i didn't find any of the latest version.
And i don't know why we can't toogle it ON... Some websites give their services to toggle it ON. but how they do that ... And no solutions for open public to counter that...
Is there a solution that i miss to pass the bootloader ON ?
Is there a cyanogen mod for xperia Z1 on lollipop for BL ON ?
Is there other solutions ?
Oh and i finally manage to ROOT my Xperia Z1 !
Thanks a lot !
Bootloader
is your bootloader is unlock now ?
Nexus line phones have always had the option to unlock the phone's bootloader. But for all other non-Nexus phone such as our Z1, there are phones with the option:
Code:
[Bootloader Unlock Allowed: Yes], and
[Bootloader Unlock Allowed: No]
There are those firmwares that you can install through a custom recovery such as TWRP on a phone with [Bootloader Unlock Allowed: No] - if I am not mistaken, those firmwares are those that use stock kernels. And those that require a phone with [Bootloader Unlock Allowed: Yes] are almost all of the time require a custom kernel.

How To Root Sony X Performance so-04h ubl no

Unfortunately, you can't flash modified firmwares without unlocking your phone bootloader.. If I'm not wrong there's no way to root Marshmallow without unlocking the bootloader.. Its only possible to root without unlocking bootloader for lollipop and lower..
