你好,
当我选择boot to download mode, 屏幕显示“This build is for development purposes only. Do not distribute outside of HTC without HTC's written permission. Failure to comply may lead to legal action.”, 然后使用数据线把HTC E9插在电脑, 打开了cmd , 输入fastboot oem get_identifier_token, 但无法解锁bootloader,显示了以下错误:
FAILED <remote: unknown command>
finished. total time:0.018s
谢谢。
