A few nights ago my ReadyNAS Ultra 6 Plus (RNDP600U) froze in the middle of me using it. I tried rebooting and it sat on the "booting..." screen for over a day. So I thought I could just do an OS Reinstall. It got an error saying it couldn't properly extract. I have not tried anything else.
I updated to 4.2.28 about a month ago without any issues.
