What was your previous firmware, and what does have now? All of the firmware upgrade versions are available at Downloads and Updates for Firmware . I’ve been running 2.11 for over a year without issue.
I recently discovered that there are early beta models that do not have upgradable firmware. Those models don’t have a USB drive, they have an SD card.
When it freezes, it’s the boot screen, not the printing screen? Previous posters have had some issues with power stability causing the controller to reboot in the middle of a print. But that usually reboots the controller, leaving it at the on-but-not-printing screen. Getting stuck on the boot screen could be a power supply issue (under voltage), but it’s more likely to be a controller issue.
