Active 2 bootloop issue

My wife's Active 2 40mm went into a bootloop. Tried all the rebooting tricks to no avail. Got an RMA from Samsung and sent it in. They claimed water damage and voided the warranty on a 9 month old watch, and wanted $210 to fix a watch that is retailing for $200 new depending on the week. No thanks, had them send the watch back. It's still bootlooping but now the display is all weird. Is there anything I can do, I'm not seeing much on repairs for this watch outside of screen replacements. I haven't seen anyone else with the same problem. What can I do?
