用http://www.htcdev.com/bootloader/unlock-instructions/page-4/連結的
Step 12
In the command prompt type:
fastboot flash unlocktoken Unlock_code.bin.
但是怎麼都是得到這個回復
c:\android>fastboot flash unlocktoken Unlock_code.bin
sending 'unlocktoken' (0 KB)... OKAY [ 0.151s]
writing 'unlocktoken'... FAILED (remote: unlock token check failed)
finished. total time: 0.159s

請問高手 這是哪裡有錯?
