Xperia M2 (2406 SeaHawk) Bootloader issues. - Sony Xperia M2

Rooting status:
Bootloader unlock allowed: Yes
Unlocking with FlashTool:
Rooting status:
unknown
Trying to unlock with cmdline (fastboot -i 0x0FCE oem unlock 0x..)
FAILED (remote: Command not allowed)
Command spamming: (Device already rooted)
I own multiple compiled .ftf's, one downloaded from XperiFirm and compiled with FlashTool. Phone is currently on D2406_SEU_1287-4567_18.3.C.0.37_R1B as requested in Xperia "Official Bootloader Unlocking" tutorial. I've unlocked bootloader before and used CM without issues, has anything changed?
I tried EagleRootToool to flash_image my way into installing TWRP on 'boot' partition in 5.1.1 but that failed since only PIE are allowed.
Has anyone dealt with this issue? I would really appreciate any help regarding unlocking the bootloader, as I've understood the bootloader is never being unlocked.

My Xperia Theft Protection disabled? It might block any unlock attempt...

[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.

Trouble unlocking device using fastboot

I purchased my pixel 2 refurbished and it said it was an "unlocked" device. However that was clearly not the case. I am afraid I have a lock down device.
fastboot flashing unlock
FAILED (remote: 'Flashing Unlock is not allowed')
The bootloader reads:
Bootloader: mw8998-002.0083.00
Baseband: g8998-00023-2004070200
Some device information... (Serial, ram etc...)
Boot-slot: a
Consoleisabled
Secure boot: Yes (PRODUCTION)
Device Starte: Locked
Is there anything I can do to get my device rooted, or am I hosed?

[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

recently bought Pixel 2(with no sim carrier) with OEM unlock enable in developer options can't unlock it bootloader.

I recently bought a new Pixel 2 to install a custom OS. In the developer option OEM unlocked is enable. but after I tried to "fastboot flashing unlock" in cmd it return this error.
FAILED (remote: 'Flashing Unlock is not allowed
')
fastboot: error: Command failed
and when I return to Developer option the OEM unlocking become grayed out.
I could return the OEM unlocking to enabled again if I factory reset the whole phone. but I still couldn't unlock the bootloader.
how can I fix this and unlock my bootloader?
edit: i tried to used "fastboot flashing lock_critical" command but the output become.
FAILED (remote: 'unknown command')
I used this platform tool: platform-tools_r33.0.2-window
(according to this thread https://forum.xda-developers.com/t/oem-unlocking-issue-solved.3716668/)
My Pixel2 OEM Unlocking was greyed out but it appeared availble to change once I rebooted having connected to the internet. Then I was able to carry on towards unlocking etc.

That's interesting, I just got a pixel 2 but unlocking is disabled, toggle greyed out after attempting. How much did you pay?
Does he have some alternative way to undo the restrictions?

I'm in the same boat, tried everything I could find.
Is your pixel 2 also set to boot-slot: B by default?
