XZ3 unlock bootloader Failed: Command did not succeed

As the title suggests, I tried to unlock my XZ3 model

 

INFO:
Bootloader unlock alowed: YES
BUILD: 52.0.A.3.202 (factory)

 

WHAT DOING:

-I do All the appropriate procedures:
-I received the unlock code from the official Sony site
- Platform-tool download and driver
-on the phone sets it basic, active developer commands
- USB DEBUG and UNLOCK OEM tip on the mobile phone menu
- I turn off the phone
-Attack the mobile in fastboot mode (blue light)
-then in the devices and printers, which appears a new one when I plug in the cel in fastboot mode, I update the driver of the device appeared, I tried both with the drivers of the model XZ3 downloadable from sony and those of google (android studio).
-I do the ADB command -> fastboot devices
  and ai read the model serial

- Then enter the code to unlock the phone: fastboot oem unlock 0xCODESEIAL
  and I get this: FAILED (remote: 'Command did not succeed')

 

I searched many guides and discussions on the net, but it always ends that I can't find a solution.

Some say that when XZ3 came out, the OEM unlock command on the phone's configurations, to wait for the December 2018 version.
Another says he unlocked it with the version: 52.0.A.3.84

 

But now we are in 2019.

 

If I update my phone, it will go directly to:
 52.0.A.8.14 then to 52.0.A.8.25 and finally to 52.0.A.8.50.
I've tried all the updates, always the same error.

 

I don't understand how to try anymore!
I searched for all possible solutions. Or maybe not.

 

Do you help me ??

Thanks

[SOLVED] Re: XZ3 unlock bootloader Failed: Command did not succeed

Fortunately, I understood the mistake.
[SOLVED] I was wrong in writing the IMEI code, and consequently the unlock code was generated wrong for my cell.
The error practically tells you: wrong code! They could waste to put a more precise message in the ADB.

Re: [SOLVED] Re: XZ3 unlock bootloader Failed: Command did not succeed

I'm not sure whether to laugh or cry at this point. After spending an entire WEEK trying to figure out why my Xperia Tablet Z wasn't unlocking, and researching solutions and workarounds, I finally realized through Flashtool that I had entered the IMEI number incorrectly all along... Plugged in the correct code and BAM, unlocked. I guess I should have heeded this thread sooner.
