I had constant freezing issues on a very regular basis until seeing what was going on. When you perform an upgrade, by following the directions in the .txt that comes with the firmware upgrade file, and then perform a scan afterwards the music database gets messed up with duplicates, which definitely is a cause of freezing. To fix it, this database should be deleted during an upgrade or downgrade of firmware. Doing a factory reset through the UI doesn't delete this database.
For the database to be deleted for a full reset you have to boot into recovery mode (shut down, turn on holding in the power button and volume up button, keep holding volume up button until in recovery mode). Do a factory reset from that screen. Also with the later firmwares, there's a folder that gets created on the root of your sd card. Plug into a computer and delete that folder. At this point you're ready to let the dx50 perform a full scan, and if that was the only issue causing all the freezing you should be good to go.
I haven't experienced a freeze on any firmware since I discovered this a couple months back, after suffering through it daily for a good month, was about ready to ask for a refund.
None of this is intuitive or user friendly. But key point to take away, do not perform a full file scan if you've already performed one and have all the database files still present from the previous scan. Don't let it perform a full scan because you added or removed some albums from your SD card, just navigate to the new folder and it will scan and add only that directory to the database. And, taking note, the regular factory reset does not wipe this database for you. So if you keep changing firmware versions, and keep performing fresh scans after each one without clearing your database it becomes a total mess.
