As an irony my device stopped working as well (as noted here for Boox 60
https://www.mobileread.com/forums/sho...d.php?t=147532) after being approx 2 days in standby mode while I was away for the weekend. Has anyone had similar problems and solutions?
Conclusion: do not buy, before the firmware is fixed.
EDIT: After a long messing with the device, I finally got it back working again. Still very angry at Onyx though.
