Hi,
I was able to unlock my bootloader following the steps on the Cyanogen site and I'm pretty sure all my drivers are sound but when I go to flash boot (fastboot flash boot boot.img) it gives me a waiting for device message. I can
Code:
fastboot -i 0x0fce getvar version
and it comes back with 0.3. I'm not a total noob at flashing. I have my boot.img ready and I'm in the right directory so I don't understand what's going on. I have an R800i.
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?
in dialer: *#*#SERVICE#*#* > service info > configuration > Rooting status. whats written under it? whats phone model r800(?)?
Try flash tool

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!

Yes. You will need the bootloader unlock key to relock the bootloader.
fastboot oem relock <bootloader key>
