Hope for the best, if you look at DX80 thread, you would be dreaded by how unreliable it is for some people. It's quite surprising, although it can be fun for someone who likes to fiddle with things. Sounds awesome though when it works.
I am still thinking that it might have to do with some cards/files/tags (I for example haven't had any of the recently reported issues with the DX80). I guess the easiest way would be for the people who are facing issues to send their Micro SD cards to iBasso so they could get around the issues. It is a total makeshift but if it finally helps solving all software issues for everyone, I guess both those people as well as iBasso would be satisfied.
