[Q]Re-Unlock bootloader after relocked

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!

Mac OS X Fastboot Mode <Waiting for Device>

Hi, I am trying to Re-Lock my Galaxy Nexus GSM version, I've downloaded the SDK files (adb-mac and fastboot-mac) and all the image files and I am trying to execute the following commands:
adb reboot bootloader
fastboot flash bootloader bootloader-toro-primekk15.img
fastboot reboot-bootloader
fastboot flash radio radio-toro-i515.ek02.img
fastboot reboot-bootloader
fastboot flash radio-cdma radio-cdma-toro-i515.ek05.img
fastboot reboot-bootloader
fastboot -w update image-mysid-icl53f.zip
fastboot reboot-bootloader
fastboot oem lock
With the phone in normal mode I connect the USB cable to the computer, start Terminal windows and run the first command, "./adb-mac reboot bootloader" and the phone will boot into the "Fastboot Mode", then I try to execute "./fastboot-mac devices" to make sure the phone is connected and properly detected and I get nothing.
If I try to execute "./fastboot-mac flash bootloader bootloader-toro-primekk15.img" I get the message <waiting for device> and it will stay there forever.
Do you know what might be the problem ?, is there other method to do this ?, go back to Stock ROM and Re-Lock the device ?, thanks
You must also install the Samsung usb drivers. I have no idea how to do this in mac. A simple search will help you tho.
