How to root Android 4.1.2 is, as I said in the title?

adb shell mount -o rw,remount -t yaffs2 /dev/block/mtdblock03 /system

adb push su /system/xbin/su

adb shell chmod 06755 /system

adb shell chmod 06755 /system/xbin/su

this code works Android 2 but doesn't work on 4.1.2.

网友答案:

Change and Try using the following line:
adb shell mount -o rw,remount -t yaffs2 /dev/block/mtdblock0 /system
