I updated to the new firmware and my HM901 no longer skips track - which is a first . There is a small downside it does not play my AAC
files anymore I only had 5 tracks on there so I have converted  them to MP3 and they play fine. Most of my music is flac so it's not really a problem. I swear it sounds different but I guess it's just my imagination

I just got the HM-901 which has the stock / firmware (1.06x).  I am trying to update, and it seems like it gets stuck on the blank screen after the Recovery mode screen.  I also tried updating to v1.082 first too, but same issue.
Any ideas?
