Help with iTunes back up decrypt iOS 9

[sc710]

I am trying to decrypt a iOS 9 back up. sorry I had 14800 (10 or greater) when I meant 14700.( 9 and below) if I am reading that wrong please correct me .

I just followed a step by step tutorial and still am receiving the same no hashes loaded response.

the input I that I built by following the video is ./hashcat -d 1 -m 14700 manifest9.txt -a 3 ?d?d?d?d?

and received ./hashcat -d 1 -m 14700 manifest9.txt -a 3 ?d?d?d?d?

as a response

after trying this input through hashcat, It still says no hashes loaded. I followed every step exactly just to get the same error.
it also says devices memory too low. (device 2)

sorry for the vague descritption and trial and error commands, but I am really frustrated, and after following a step by step procedure I still received the same response..
after following everything step by step I don't see why I would receive a no hashes loaded response unless there was some sort of issue..

please help me understand.

this is the tutorial I followed.
