Reinstall dashboard (i've broken dashboard)

See the various discussions on how to unbrick the My cloud device. So long as you do not touch the fourth partition ( sdb4) which typically is the user partition, one should be able to push the correct files, depending on which My Cloud model one is using, to the My Cloud to restore it’s function. Note that there are two different models for the single bay/single drive My Cloud. The process used to restore it is different for each version. See the following discussion started a few days ago where someone asked a similar question about recovering their My cloud without loosing data.
