Is there a way to downgrade the firmware on the M2X? I'm currently on the latest firmware (3.3), and sometimes I'm experiencing hard lockups (music stops playing and entire player freezes), needs a hard restart to fix things (holding the power button until it's off and turn it on again).
You can downgrade by downloading an older version on Shanlings website, then manually trigger firmware update using SD card as source.
I am having similar issues with M5s which is basically the same OS as used in M2X. In my case the player freezes when doing the following:
1. play song on Tidal and pause
2. go into standby mode
3. wake up from standby mode
At first the WiFi needs to reconnect but the player already tries to playback the song.
For M5s unfortunately downgrading by one release did not help.
And interestingly I am not having these resume/freeze problems on M2X on latest firmware 3.3… only on my M5s.
Either way, I hope Shanling can fix it for both players.
