I have Android 4.1.2 Jelly Bean official update on my smartphone, which I updated with Samsung's Kies over USB cable.
From curiosity I downloaded the rooting package http://d-h.st/ook and looked at root/META-INF/com/google/android/updater-script
In a nutshell, rooting is adding su (SuperUser) binary into /system/bin.
ui_print("***************************");
ui_print("Rooting with SuperSU 0.95 & Busybox 1.20.2");
ui_print("***************************");
show_progress(1.000000, 0);
ui_print("Installing temporary busybox");
package_extract_file("system/xbin/busybox", "/tmp/busybox");
set_perm(0, 0, 0777, "/tmp/busybox");
set_progress(0.200000);
ui_print("Mounting system...");
run_program("/tmp/busybox", "mount", "/system");
set_progress(0.300000);
ui_print("Removing old superuser");
delete("/system/bin/su");
delete("/system/xbin/su");
delete("/system/app/superuser.apk");
delete("/system/app/superUser.apk");
delete("/system/app/Superuser.apk");
delete("/system/app/SuperUser.apk");
set_progress(0.400000);
ui_print("Installing Superuser & Busybox...");
package_extract_dir("system", "/system");
set_progress(0.600000);
ui_print("Setting Permission...");
set_perm(0, 0, 06755, "/system/xbin/su");
set_perm(0, 0, 0644, "/system/app/superuser.apk");
set_perm(0, 0, 04755, "/system/xbin/busybox");
set_progress(0.700000);
ui_print("Installing Busybox...");
run_program("/system/xbin/busybox", "--install", "-s", "/system/xbin");
set_progress(0.900000);
ui_print("Symlinking...");
symlink("/system/xbin/su", "/system/bin/su");
ui_print("Unmounting system...");
run_program("/tmp/busybox", "umount", "/system");
ui_print("Deleting temporary busybox");
delete("/tmp/busybox");
set_progress(1.000000);
show_progress(1.000000, 0);
ui_print("Root complete!");
ui_print("SuperSU 0.95 & Busybox 1.20.2");
After reading and playing around with adb I decided that I go for it
For strengthening my decision a checked if the MD5 matches and it matched
mike@mikembp:~/Downloads/android$ md5 root.zip MD5 (root.zip) = 3d5cc207f625a032e7ff4fe92e3e6efa
Trying su after restart
