[Q]Re-Unlock bootloader after relocked - Xperia Arc Q&A, Help & Troubleshooting

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!

Able to unlock bootloader but not flash anything

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.

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!
