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?
I've installed all the correct drivers and followed all the instructions, typed in 'fastboot.exe -i 0x0fce getvar version' in cmd and it responds correctly, but when I type 'fastboot.exe -i 0x0fce oem unlock 0x8953C6AC2154D8C9' to unlock the bootloader, it always gives me the same error;
FAILED <remote: oem unlock failed!>
can someone help me?

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!

So a quick thread here. Asus devices won't be unlocked by the common commands which are
Code:
Fastboot oem unlock
Fastboot oem unlock confirm
From now on, asus uses there own codes.
Here it is
Code:
Fastboot oem asus-go
Fastboot oem asus-go confirm
This is not a guide. If you use the old command it will return an error UNKNOWN COMMAND.
Thanks !

Hi, I need some help with unlocking the bootloader of my phone [Huawei Y5 (DRA-LX3)] Please!
So, I am using the adb7fastboot method to unlock the bootloader, there are very limited options to do this process, but I've managed to find what might be the unlocker code for the command:
Code:
fastboot oem unlock xxxxxxxxxx (the unlock code)
Naturally, the warning screen appears on my phone (the one that tells you about erasing all of the data by unlocking the phone), and when I select "Yes" the phone displays an error:
unlock failed... return to fastboot in 3s
And the adb/fastboot window goes something like this:
Code:
...
(bootloader) Start unlock flow
FAILED (remote:
Unlock failed - Err:0x7
)
finished. total time: 6.137s
What do you think? Is there a solution that can save my life? Thanks by the way!
