1. Firmware 6.0.46G 2. Power button configured to standby. 3. Startup Z9X normally. 4. Launch ZDMC 18.8, let it startup and then idle. 5. Use remote control, press power off button. 6. Z9X will initiate standby, screen goes black then goes grey, clock display remains on. 7. Z9X does not respond to remote control power button or any other button. Zidoo app cannot connect to it. Zidoo box is officially frozen dead. Only cutting main power can recover the box. Bad bug ... ** If power button is configured to shutdown, no problems, box will shutdown properly, clock display switches off, and the red LED will light up when done.
Happens only when running ZDMC it seems. I tried without ZDMC and then standby works just fine for me. Apparently ZDMC is behaving badly when moved to standby. You can try an older version to see if it came with the ZDMC18.8 update. That will help solving it.
It also happens when using media center to play music. While music is playing, use remote to standby the unit, it will initiate standby then freeze dead. For media center, sometimes it can standby successfully (maybe 20% of the time).
Just tried sleep music running active with Music Player. No problems found. I would do a factory reset to clean the box.
