Can you access the My Cloud Dashboard? If so does it show any errors in the Alert/Notification Icon section or does the diagnostic section indicate an error? The flashing blue LED can mean a number of things from indexing to some other issue.
As previously indicated, because you were apparently following the USB method for unbricking a second gen single bay My Cloud, you may have to try that process again. Sometimes one has to perform the process several times because they didn’t follow the correct procedures the first time.
You may have to copy the user files/data off the drive to another location and follow the full unbrick procedure which involves partitioning and formatting as the directions indicate.

Or search the subforum for flashing blue LED to see if there are any other suggestions. Seems to be a common issue after one tries to unbrick a My Cloud and the process wasn’t completed properly.
