Unlock Bootloader MacOS Z5 Simple sim - Xperia Z5 Q&A, Help & Troubleshooting

Hi Guys,
Been through the whole net and lots of threads but it seams that I am stuck at:
fastboot -i 0x0fce oem unlock XXXXXXXXXXXXXXXX
...
FAILED (remote: Command not allowed)
finished. total time: 0.009s
I have installed ADB, checked it worked but is seems that fastboot cannot talk to my phone, all other fastboot commands (apart from help) are returning "FAILED (remote: unknown command)".
Note: I have the same error using flashtool, is there something wrong with the phone, maybe because branded (in France).
Any help would be greatly appreciated.

Do you have the "Enable OEM Unlock" option enabled in the developer settings?

[E1] Bootloader Unlock Problem (important!)

So. I would like to unlock the bootloader. All fine, I get the code, and when I type in
Code:
fastboot -i 0xfce oem unlock 0xcodehere
it says
Code:
FAILED: Command did not succeed.
However, when I do it the second time (enter the command right again) it says OKAY but the device will end up on a bootloop next start, and when I try to flash a kernel, it says not allowed.(fastboot) If I flash when unlocked without restarting device, the device will shut down at SONY logo. Is it possible that I got a temporary unlock? How could I unlock the device successfully?(permanently) I tried it with Flashtool, and the same results. I literally tried everything. I also cannot install the permanent OS-independent CWM because of the shutdown at the SONY logo. I didn't yet contact my service provider, but I don't think they would like the idea. I really want CyanogenMod on my device, and I'd also like to fix some problems if I can. Please try to help ASAP. Thanks!

I have the same problem. Did you resolve it?
Open Phone and dial *#*#7378423#*#* go to Service Info->Configuration if Rooting Status says Bootloader unlock allow: No you can't unlock it. If it says Yes go to Sony's official website for unlocking and follow the instructions.
Good Luck.

How can I unlock the bootloader?

I've tried Sony's instructions but when I run fastboot, I get this error:
Code:
FAILED (remote: Command not allowed)
This is the command I run:
Code:
fastboot -i 0x0fce oem unlock 0x0
I removed the last part on purpose.

Have you turned off/disabled my Xperia and enabled the oem unlock in the developer options.

May I ask you (or anyone else !) what device to chose in Sony's devices list ?
I don't see Xperia XZ.
Or it doesn't matter ?

[Q] Unlock bootloader of Wiko Rainbow sibling: Wiko Y80

Hi everybody,
I know this is a thread about Wiko Rainbow not about Y80, but maybe someone had the following problem in the past...
I would like to unlock the bootloader of a Wiko Y80 to install a custom ROM.
On the Internet, there are many pages where there is the same guide (written in different ways) for unlocking the bootloader using 'fastboot'.
The problem is that 'fastboot' does not work because:
fastboot flashing unlock > FAILED (remote: Not implemet.)
fastboot oem unlock > FAILED (remote: unknown cmd.)
fastboot oem get_unlock_data > FAILED (remote: unknown cmd.)
fastboot flashing unlock_critical > FAILED (remote: Not implement.)
By chance, does anyone know if there is another way for unlocking the bootloader or, even better, to flash a ROM like LineageOS GSI?
I would like to have some news from guys who really made/tried it successfully.
Thanks,
Roberto
I hoped i would be able to do this as well but nope, no luck
I managed on Y61 just enable oem unlock in developer settings then run
Code:
fastboot flashing unlock
