sony do not have the data of the phones unlocked unofficially. so if you brick your phone you can relock the bootloader with TA partition and DRM keys so that you can flash stock firmware using flashtool ( or repair using PCC ). Then you can visit service center

XPERIA Z - bootloader unlock allowed: no, but fastboot working.

I'm buying Xperia Z (SFR C6603) sim unlock or sim free i don't know.
Working with all sim cards.
I have problem: phone say bootloader unlock allowed: no,but fastboot & flashmode working.
Can i unlock bootloader or not? thanks. sorry for my bad english.
No you can't if it says no.
Fastboot works on all Sony phones, and on not unlockable roms it can be used to flash a pure stock kernel if you want. But you can also do that via recovery with the right update script or with ftf.

How to flash back Dual sim E6553 instead of E6533

Hi all
A friend of me asked me to unlock his Sony Xperia Z3+
It is the dual sim version, E6553
It had the Xperia lock and a tried different solutions to unlock it, without any success.
I also asked a friend to experiment.
He couldn't unlock it, but when I got back the phone, it had the single sim software, for E6533. Still locked.
Now I unlocked the phone. I made a reset, I can update the firmware, but I cannot flash the E6553 back.
If I try, I get this error:
ERROR - The bundle does not match the connected device
I tried with older flasher, but I get another error:
INFO - Cannot open bundle. Flash operation canceled
I also tried with Emma, but it says Phone is locked. (I already unlocked bootloader)
Phone works correctly with this firmware, but I want to use it with 2 sim cards.
Please advise.
Best regards,
Janos
