Unlocking bootloader - Xperia Z1 Q&A, Help & Troubleshooting

When I check if I could unlock bootloader by that number, it says no, so I do not have possibility to unlock bootloader officially (it is denied by my operator), but can I unlock it anyway and how? Thanks for help

This have nothing to do with Unlocking Bootloader. Unlock Butloader now and you will be fine, with 4.3 the camera was fixed.
but on the info about bootloader unlocking it says not to proceed if bootloader unlock is no in service menu i dont wish to end with a brick

Have you tried unlocking? When this has happened on Xperia T's the devices were still able to be unlocked even though that had changed. There is absolutely no risk in trying to unlock an unlockable bootloader, it will just fail in the process and will still boot no problem.
It has never been reported a NO had turned to YES, but some Yes had been turned to NO, and they were still bale to be unlocked.
And before anyone gets excited this is by no means something that can be used to unlocked bootloaders that are really locked, it is just a false reading of the boot status.

Ok, so it's risky. Is not a big problem even if you don't unlock the bootloader but are you sure was saying yes before? this is wired.
You can flash updates and custom roms anyway. Not custom kernels. Sorry.

Open the dialer and press this *#*#7378423#*#* to open the service menu
then go to service info, then configuration
Then if under rooting status it is written bootloader unlocked : yes , that means your bootloader is unlocked
thanks but it only says that it is allowed to unlock the bootloader. but i want to see that i have sucsessfully unlocked my bootloader.

if it says it is allowed to unlock bootloader that means it has not been unlocked you still have to unlock it

The answer is in your post. Your bootloader is unlocked, you never relocked it. Put your phone in fastboot and you will see a violet led...
Yeah it seems your bootloader is still unlocked.
No my phone bootloader not unlocked now, and when l connect my phone in FASTBOOT mode the flash is blue
And also l cannot install cm12.1 because bootloader is not unlocked
Sorry, my English is not good
What is problem??? :crying:

Long time ago i saw a thread that a user was telling that he wasn't able to unlock the bootloader when he has using certain ftf files. It is pretty strange actually.
Try to downgrade your phone, maybe installing kk and try again mate.
Maybe this will help if you already don't know it. Take a look here. Way old that thread but maybe still guilty.

Post #2 says you have to be on stock kernel to relock your bootloader.

Congratulations. Glad I could help. You can give me a thank if you don't mind.
What do you mean with fresh kernel? You mean stock kernel, aren't you?
