請教一下android fastboot 兩個問題
 

1.我做了這一個動作 fastboot oem unlock-go 想反悔
fastboot oem lock 出現此訊息 FAILED (remote: unknown command) ??
刷回原廠完整包，recovery 已刷不進去??但系統開機正常
為何解鎖反刷不進去? 如何 undo ?

2 fastboot -i 0x0489 oem idme bootmode 0x4000
FAILED (remote: unknown command)
finished. total time: 0.016s
另外
adb shell idme bootmode 0x4000
/sbin/sh: idme: not found

idme 是什 ??
