1. 需要 root 权限
代码修改点:
/system/extras/su/su.c
60 /* Until we have something better, only root and the shell can use su. */
61 myuid = getuid();
62 if (myuid != AID_ROOT && myuid != AID_SHELL) {
63 fprintf(stderr,"su: uid %d not allowed to su\n", myuid);
64 return 1;
65 }
67 if(setgid(gid) || setuid(uid)) {
68 fprintf(stderr,"su: permission denied\n");
69 return 1;
70 }
把63,64,68,69 行注释掉,编译生成su,然后push到设备。
adb push su /system/xbin/
adb shell chmod 6755 /system/xbin/su
2. 安装 adbwireless 软件,一键搞定
在电子市场上搜 adb,前面两个随便选一个都行。
如果电子市场上不了,在 Terminal Emulator 直接输入:
setprop service.adb.tcp.port 8000
stop adbd
start adbd
通过adb 连上设备,下面是我机器上的操作结果:
deli@deli-laptop:~$ adb connect 192.168.1.103:8000
already connected to 192.168.1.103:8000
deli@deli-laptop:~$ adb shell
# busybox sh
/ #
