本文介绍了如何在Android 9的用户版本中启用fastboot调试。通过强制启用特定的宏开关，如ENABLE_UPDATE_PARTITIONS_CMDS, ENABLE_DEVICE_CRITICAL_LOCK_UNLOCK_CMDS和ENABLE_BOOT_CMD，可以在user模式下使用fastboot命令。" 109303481,8753399,C++抽象工厂模式详解,"['设计模式', 'C++编程', '软件设计']

从如下代码中可以看到，fastboot的命令是由这几个宏打开的，只要在user模式下强制使能这几个宏开关即可

#define ENABLE_UPDATE_PARTITIONS_CMDS
#define ENABLE_DEVICE_CRITICAL_LOCK_UNLOCK_CMDS
#define ENABLE_BOOT_CMD

          struct FastbootCmdDesc cmd_list[] = {
      /* By Default enable list is empty */
      {"", NULL},
/*CAUTION(High): Enabling these commands will allow changing the partitions
 *like system,userdata,cachec etc...
 */
