Fix Samsung error “Unauthorized software detected” when flashing with Odin

Did you try flashing CWM, CF Autoroot or TWRP recovery in Odin only to see a Kies error saying “Unauthorized software detected on phone” with an exclamation point?  The fix for this is very simple.  All you have to do is use a newer computer because chances are the computer you are using either has slow USB ports or is old computer.

After switching to a newer computer I noticed I booted up into CWM just fine.

You can also try switching USB cables because that makes a big difference.
