android adb 权限修改

1. 修改 ADB ROOT权限:

system/core$ git diff adb/adb.c
diff --git a/adb/adb.c b/adb/adb.c
index 99bea0f..d8fc090 100644
--- a/adb/adb.c

+ else
     return 1;
 #else /* ALLOW_ADBD_ROOT */

同时在system.prop中添加hw.hasusbadbroot=1

2.去掉adb 密钥校验：

ro.adb.secure=0

3.修改开发者选项隐藏

packages/apps/Settings/src/com/android/settings/Settings.java

     private void updateHeaderList(List

-        final boolean showDev = mDevelopmentPreferences.getBoolean(
