Have you double checked your unlock code? Or have you checked the root status like darkharbinger81 said. Both are common mistakes. Very easy to check too.
Bootloader unlocked: Yes.
R800i
Android version 4.0.2.a.0.42
Do I need to root it first? And the same error surfaces for my Xperia Sola... MT27i, stock 6.1.1.B.1.54, BL unlock: yes

Check (and doublecheck) what IMEI number you entered in Sony's site.
Type in dialer *#*# 7378423#*#* , go to service info> configuration and check your IMEI.
And IMPORTANT, that number will be 15 digits, but in Sony's site for bootloader unlocking you enter only 14 digits (ignore last digit)
If that fail, try some other thing:
-put usb cable in back usb ports of your motherboard
-try different usb cable
And finaly, as i recall, try by typing 0xfce instead of 0x0fce ( 'fastboot.exe -i 0xfce oem unlock 0xKEY)
Okay I went through the whole procedure again, double checked everything, the website gave me a different code and it worked this time. Thanks everybody!

Had anyone tried it before?
After I unlock my bootloader using the official method, it is a silly way to unlock your Arc S bootloader. You will lost your DRM key and FOTA bricked, I learned my lesson. If you want to unlock your phone Testpointer method is obviously a better way.
So I relock my bootloader again using a common method you can find online:
http://forum.xda-developers.com/show...php?p=20422618
fastboot flash -i 0x0fce getvar version
fastboot flash -i 0x0fce oem unlock 0xKEY
Error: cannot load '0x0fce' is what I got after execute these command.
I am so desperate to get my bootloader unlock again and manage to switch between locked and unlock state.
Is there something to do with preset.ta file so I can unlock my device again. If the re-lock patch involving this file.
Well! It seem to solved.
Using following command:
fastboot getvar version
fastboot oem unlock 0xKEY
Thanks you guys!
Hey i had sucessfully unlocked the bootloader on my Xperia Pro, however the speaker broke and i had to send the phone to service. So i relocked the bootloader by flashing a flt found here the file is called Xperia_Relock_bootloader.ftf
*I cant post links yet*.
Today i got my phone back, the service replaced the speaker on the phone, so now it works =D
However i can't no longer unlock the bootloader - here's how i have done.
1) i have installed the fastboot drivers from the FlashTool drivers.
2) Ive followed the intrsuctions given by Sony Ericsson, i entered my IMEI key
and were returmed an unlock-key to unlock the bootloader
3) Rooting Status in the Service menu says:
Bootloader unlock allowed: Yes
4) ive ran fastboot.exe -i 0x0fce getvar version and i were returned 0.3
5) The last step ive ran fastboot.exe -i 0x0fce oem unlock 0xKEY were KEY is the key i got from Sony Ericsson,
however i am being returned this
(bootloader) Unlock phone requested
FAILED (remote: oem unlock failed!)
finished. total time: 0.004s
What am i doing wrong?
Hi , when i enter this fastboot.exe -i 0x0fce getvar version i get 0.3 all good
when i enter this
fastboot.exe -i 0x0fce oem unlock 0x ( the number sent me ) I get failed phone already unlocked
but when i start the phone its not rooted ? I did try doomlord with no luck
Many thanks and Happy new year
Bootloader unlocking doesn't give you a rooted Phone.
Put superuser.zip form their site on your sd card
Hotboot a kernel now with cwm. Install zip

Learn the difference between "unlocking bootloader" and "rooting".
I have tried running these in the fastboot:
Code:
fastboot oem unlock
fastboot flashing unlock
None of them works. The first command gives
Code:
Unable to open fastboot HAL
and the second one gives
Code:
Unrecognized command flashing unlock
.
I just want to root the phone. Overall, the phone seems great, but it is fested with nasty oem apps that I don't want to use. :crying:

Are you rooted your phone?
Did you enable 'OEM unlocking' in the developer options?
You can uninstall some apps this way

Hi there,
I try to install lineageos on my xperia xz2 compact but i dont manage to get the bootloader unlocked.
The rooting status says : Bootloader unlock allowed: Yes. so i thought it should be fine but in fastboot mode the command
Code:
fastboot oem unlock <unlockcode>
gives me:
Code:
...
FAILED (remote: Command not allowed)
finished. total time: 0.069s
I tried with flashtool (found this in some forums) but i get some error as well. Even though i am not sure to use this program properly and I also got some
"No device is registered in Flashtool. You can only flash devices."
error message there.
any ideas?
problem solved, I didn't know that I would have to enable "oem unlock" in the device's developper options. what a fail..
