fastboot unlock FAILED

I'm trying to allow bootloader unlock but keep getting the error above. I've seen various posts on this in the past but am still stumped after doing the following :
- the phone is an xperia Z3 compact
- enabled Developer options
- enabled USB debugging
- allowed installation of apps from unknown sources
- set 'Install software' with USB Connectivity
- unlocked sim (network unlocked)
- received unlock code from Sony
- running software on Ubuntu linux
Commands I've run
=================
fastboot -i 0x0fce oem unlock 0xB9D9999DF99BDB9A
...

Anybody got any other ideas ? Thanks in advance.

I think the problem is that the setting of "Bootloader unlock allowed: No" can't be unset other than by Sony. I have contacted them but I'm not holding my breath.

There seems to be 2 fastboot modes. One when I reboot to bootloader and I get fastboot to detect device. Different message than in the download mode, it has a recovery like menu but the options are different. There is one for usb-debug mode which just reboots the phone.

Howto unlock bootloader?

How can I unlock the bootloader? I followed instructions on the sony side but it doesn't seem to work:
(1) I went into the servie menu to check the status by dialling *#*#7374823#*#* -> Service info -> Configuration. It says: "Bootloader unlock allowed: Yes"
(2) While in the service info, I also wrote down both IMEI numbers (each 15 characters long)
(3) Aftwerwards I enabled dev options, allow usb-debugging and oem unlocking of bootloader
(4) I went to Sony's side to create the unlock code: https://developer.sony.com/develop/open-devices/get-started/unlock-bootloader/
(5) I did issue adb reboot bootloader, the phone rebooted and the notification led was blue
(6) then I entered the unlock code:
fastboot oem unlock 0x<insert your unlock code>
but only this error appeared:
FAILED (Write to device failed (Cannot send after transport endpoint shutdown))
fastboot: error: Command failed
Where did I go wrong?

[HELP] Unlock bootloader without OEM Unlock (Phone doesn't start)

¡ I need help please !
I have a HTC Desire 10 pro (From Aliexpress, yes warranty avoid), it was working fine (more than a year) until a few days ago. One morning I took it and it was off but the notification led was not on despite charging. I tried to turn it on and enter to recovery but it was not responding. I decided to open the phone to remove the battery and verify that it was not damaged. Mysteriously the battery was in good condition, and once I removed it and plugged it back in, the phone responded again when connecting the USB and the charger.
But there is a problem, when the system is going to boot, after showing the HTC logo, the phone turns off together with the notification led and returns to the state in which I found it at first.
I removed and placed the battery again so that it would respond again, but now I entered to recovery to make a reset, but the problem is that the recovery is very outdated, so it does not have the "wipe data" options.
It should be said that i can enter into a "recovery mode" that shows:
"

Where the blue txt is the actual menu.
In this "recovery mode" I can't use ADB commands, i only can execute some fastboot commands (PC recognizes my device because of fastboot drivers) as "reboot", but for example:
* I can't use the "erase" command because my current recovery is not supported:

erasing 'userdata'...

* Nor I can directly install the TWRP recovery because it tells me:

Well, this is the situation, and i think the solution is:
install the TWRP recovery to do a factory reset and if necessary install a ROM (official or not).
Buuut, to install the recovery I need to activate USB debugging (MANUALLY in the android options) and activate the OEM unlock option to unlock the bootloader, which is impossible for me since the phone "turns off" before starting.
My question is:
How to activate OEM unlock option without having to access to android settings? I mean, with commands in fastboot or in some software.
I have searched a LOT on the internet and I can't find anything about it, all the tutorials have the device fully functional, not like me that my device does not start.

Question NE2217 Can't unlock my bootloader

I got my token, hit oem unlocking. Rebooted to fastbootd mode, then I use fastboot flash cust-unlock. Which returns,
C:\Users\James>fastboot flash cust-unlock C:\Users\James\Desktop\10pro\unlock_code.bin
Sending 'cust-unlock' (0 KB) FAILED (remote: 'Download is not allowed on locked devices')
fastboot: error: Command failed
If I try it without cust-unlock I get,
C:\Users\James>fastboot flash C:\Users\James\Desktop\10pro\unlock_code.bin
unknown partition 'C:\Users\James\Desktop\10pro\unlock_code.bin'
fastboot: error: cannot determine image filename for 'C:\Users\James\Desktop\10pro\unlock_code.bin'
If I fastboot reboot to bootloader and do the same command I get,
C:\Users\James>fastboot flash cust-unlock C:\Users\James\Desktop\10pro\unlock_code.bin
Sending 'cust-unlock' (0 KB) OKAY [ 0.002s]
Writing 'cust-unlock' (bootloader) Device is unlocked.
OKAY [ 0.004s]
Finished. Total time: 0.099s
But, that doesn't actually unlock my bootloader. Can someone please help?

Here's some more I have tried
C:\Users\James>fastboot flashing unlock

I was able to hit oem unlock so it shouldn't be sim related, but thanks for helping

Four things:
Name of file doesn't matter
SIM unlock and bootloader unlock are separate things
Move the unlock.bin to the same folder as your platform tools so you don't have to put the entire the path. Or put it in quotation marks
Is fastboot in your system PATH? If not, prefix fastboot to look like this
Code:
./fastboot.exe

Also, what does the following command return?
Code:
fastboot devices

centifanto said:

C:\>fastboot devices
*serial number* fastboot
Also not too sure what you mean, "Is fastboot in your system PATH? If not, prefix fastboot to look like this"
But it is installed to my system drive. Even tried downloading new platform tools and trying it in my root drive of C:\

No worries. If you got the "5497b039" returned it means fastboot is working for you and your device is in the correct bootloader mode.
Does your device display "locked" in red letters?
Are you sure that "OEM unlock" is still toggled in the developer settings?

Okay so I got it, thank you for the help.
Did the commands you sent in the bootloader menu, guess I missed the second.
For anyone who can't unlock the bootloader I'll post simple instructions, on the NE2217
OEM unlock - on
adb reboot bootloader
fastboot devices
fastboot flash cust-unlock unlock.bin
fastboot flashing unlock
anyone can add anything else
