on the instructions where it says: Once ready, type these commands in cmd prompt from your adb tools directory. After every line press enter.

adb push flash_image /data/local/
adb push rageagainstthecage-arm5.bin /data/local/tmp/
adb push mtd0.img /sdcard/

you might have to navigate the command prompt to the directory where you have adb installed
...those instructions directed you to download the android sdk to the root of your c:\ ... so your command prompt should read:
C:\android-sdk-windows\tools
before attempting any of those commands, if you downloaded the sdk to another loacation
you will have to point the command prompt to that location... hope this helps

and PS make sure USB debugging is enabled on your phone and you have the correct drivers installed

I think he means you need to SHIFT + right click and select CMD, or cntrl + rt click? in the folder

ok but for the adb? Once ready, type these commands in cmd prompt from your adb tools directory. After every line press enter.
What do i do here?^
