What happens if you try to run again the software? We could try it again with different cables and if it doesn't work, could you attach the log files?
But, if you are still getting those errors while trying to flash the image we could try with the flashall script. For this, you need to download this file into the folder where you have the files for your Edison (FlashEdison.json, flashall.bat, flashall.sh .....)
Now, you have to open the cmd.exe and go to the folder where you just put the file and run the next line in the Console.
Then, plug your board to your PC and wait for the process to be done.
Start a session with Putty and log-in into you board to check if it's booting correctly.
