WRITE_SECURE_SETTINGS无法识别

Question

我正在尝试通过adb运行以下内容，以便将WRITE_SECURE_SETTINGS授予我的Marshmallow Rom。

我的手机已经扎根了。

但是我得到了这个例外：

1|root@:/ # pm grant by4a.setedit22 Android.Manifest.permission.WRITE_SECURE_SE
TINGS
.setedit22 Android.Manifest.permission.WRITE_SECURE_SETTINGS                  <
Bad argument: java.lang.IllegalArgumentException: Unknown permission: Android.M
nifest.permission.WRITE_SECURE_SETTINGS
usage: pm list packages [-f] [-d] [-e] [-s] [-3] [-i] [-u] [--user USER_ID] [FI
TER]
       pm list permission-groups
       pm list permissions [-g] [-f] [-d] [-u] [GROUP]
       pm list instrumentation [-f] [TARGET-PACKAGE]

有人可以帮助我吗？
