Unable to find a UFI image copy from. Please reload master with appropriate UFI image to proceed wit

[Angel]

Hi,

Im trying to connect my switch (as it appears disconnected) by following one of the threads here and changing the SPR boot to the SPS boot (not sure if that's the term), and have gotten the message:

"Unable to find a UFI image copy from. Please reload master with appropriate UFI image to proceed with flash-flash copy"

This problem has been happening since I had a major power outage after a hurricane. My internet is spotty and/or non-existent. 

Please help. I work from home and desperately need fluid internet connection. 

Thank you for your time,
