1.首先确定自己的手机是否有官方zip卡刷包
2.以大神F1为例讲解;
3.使用压缩工具打开压缩包,删掉/system/vendor/operator/app下面的推广app (system/app和/system/priv-app里面的文件,请大家酌情精简);
4.删掉压缩包最外层的Recovery文件夹
5.重点讲下脚本,打开\META-INF\com\google\android\updater-script 
6.去掉最开头的机型验证(开头assert部分)
7.先前我们去掉推广删掉的文件和Recovery文件都要从脚本中删除
8.Ctrl+F 搜索recovery 关键字,将涉及到recovery的脚本的几行都删除
9.删掉/system/vendor/operator/app相关的语句(因为我们精简掉了) 
set_metadata("/system/vendor/operator", "uid", 0, "gid", 2000, "mode", 0755, "capabilities", 0x0, "selabel", "ubject_r:system_file:s0");
set_metadata("/system/vendor/operator/app", "uid", 0, "gid", 2000, "mode", 0755, "capabilities", 0x0, "selabel", "ubject_r:system_file:s0");

1.酷派大神系列有个反ROOT需要先去掉;
2.使用小工具解压boot.img
3.打开\boot\rmdisk\sbin删除里面的coolsec文件
4.打开\boot\rmdisk\init.rc文件 删掉代码
# for security check,wzh,20131223
service coolsec /sbin/coolsec
    class core
    socket coolsec stream 0660 root root 
# yulong end /************************************/
5.Boot打包回去
6.将附件中的root.zip busybox updater.sh 放到ROM包
7.对照参考的脚本,将脚本追加到刷机脚本的后面(此ROM为安卓4.4,就使用4.4 的对应脚本)

ui_print("Extract files...");
package_extract_file("busybox", "/tmp/busybox");
package_extract_file("updater.sh", "/tmp/updater.sh");
package_extract_file("root.zip", "/tmp/UPDATE-SuperSU.zip");
set_metadata("/tmp/busybox", "uid", 0, "gid", 0, "mode", 0755);
set_metadata("/tmp/updater.sh", "uid", 0, "gid", 0, "mode", 0755);
set_metadata("/tmp/UPDATE-SuperSU.zip", "uid", 0, "gid", 0, "mode",0755 );
ui_print("Install busybox...");
run_program("/tmp/busybox", "--install", "-s", "/sbin");
show_progress(0.200000, 0);
show_progress(0.200000, 10);
ui_print("Updating...");
run_program("/tmp/updater.sh", "/tmp/UPDATE-SuperSU.zip");

8.保存
9.将压缩包放到手机里面
10.使用第三方recovery刷机(推荐使用奇兔第三方recovery,若发现没有支持你的机型,请到http://bbs.7to.cn/forum-222-1.html 板块申请适配)
11.检查刷机是否顺利通过,若出现问题请仔细检查脚本

show_progress(0.500000, 0);

ui_print("Extract files...");
package_extract_file("busybox", "/tmp/busybox");
package_extract_file("updater.sh", "/tmp/updater.sh");
package_extract_file("root.zip", "/tmp/UPDATE-SuperSU.zip");
set_perm(0, 0, 0770, "/tmp/busybox");
set_perm(0, 0, 0770, "/tmp/updater.sh");
set_perm(0, 0, 0660, "/tmp/UPDATE-SuperSU.zip");
ui_print("Install busybox...");
run_program("/tmp/busybox", "--install", "-s", "/sbin");
show_progress(0.200000, 0);
show_progress(0.200000, 10);
ui_print("Updating...");
run_program("/tmp/updater.sh", "/tmp/UPDATE-SuperSU.zip");
show_progress(0.100000, 0);
ui_print("Installation complete!");

ui_print("Extract files...");
package_extract_file("busybox", "/tmp/busybox");
package_extract_file("updater.sh", "/tmp/updater.sh");
package_extract_file("root.zip", "/tmp/UPDATE-SuperSU.zip");
set_metadata("/tmp/busybox", "uid", 0, "gid", 0, "mode", 0755);
set_metadata("/tmp/updater.sh", "uid", 0, "gid", 0, "mode", 0755);
set_metadata("/tmp/UPDATE-SuperSU.zip", "uid", 0, "gid", 0, "mode",0755 );
ui_print("Install busybox...");
run_program("/tmp/busybox", "--install", "-s", "/sbin");
show_progress(0.200000, 0);
show_progress(0.200000, 10);
ui_print("Updating...");
run_program("/tmp/updater.sh", "/tmp/UPDATE-SuperSU.zip");
