Hi Everyone, attempting to update firmware on an Intellitouch Mobi 2 520906. It presently holds v1.17. I've been able to update the indoor remote panel and outdoor control panel to 1.19 however unable to get the Mobi to update. I have tried it powered and unpowered. Erased memory on the unit. I'm thinking that this may have something to do with the RF antennae/wireless link. I have had success with a past Mobi on another system - took it home left it unpowered for a few days then updated it. This one however is being resistent. Pentair tech support wasn't helpful. Any thoughts out there?
