adb root 后为什么出现
“adbd cannot run as root in production builds”
看看下面的代码就懂了，你也会知道怎么去改了！
~/mywork/403-sync/system/core/adb/services.c/
110 void restart_root_service(int fd, void *cookie)
111 {
112 char buf[100];
113 char value[PROPERTY_VALUE_MAX];
114
115 if (getuid() == 0) {
116 snprintf(buf, sizeof(buf), "adbd is already running as root\n");
117 writex(fd, buf, strlen(buf));
118 adb_close(fd);
119 } else {
120 property_get("ro.debuggable", value, "");
121 if (strcmp(value, "1") != 0) {
122 snprintf(buf, sizeof(buf), "adbd cannot run as root in production builds\n");
123 writex(fd, buf, strlen(buf));
124 adb_close(fd);
125 return;
126 }
127
128 snprintf(buf, sizeof(buf), "restarting adbd as root\n");
129 writex(fd, buf, strlen(buf));
130 adb_close(fd);
131
132 // This will cause a property trigger in init.rc to restart us
133 property_set("service.adb.root", "1");
134 }
135 }
