my mycloud dl2100 was working fine for many many years. last time i checked, it did a firmware update and never started up again. its flashing blue, with fans very loud. it does this for a few minutes then powercycles and repeats the process again.
its been going on for hours and Im suspecting the last firmware update failed.
how do I recover it to a previous known working firmware, perhaps using a USB stick?
Please help. A lot of important files are on this drive.
