UConnect Stuck in a Restart Loop?

Has any found a resolution to the u connect 8.4 reboot loop? I had my 17 HC in to dealer today for an update from original 14.9 to 16.12 to fix some Bluetooth issues and the unit now loops in reboot. They're saying I may need a new head unit if it doesn't settle down but I'm thinking the update might not have completed successfully. They did the fuse 37 pull but no help. I didn't do hard reset yet. There is an extended Mopar warranty on my car but still don't want the dash pulled apart and a refirbed unit installed if we can avoid it. Dealer also found something about Sirius travel services needing to be disabled and leaving the car running exposed to sky for 30 minutes but that solution seems like a stretch. Thanks for any info.

I've tried just about everything, pulled amp radio and usb hub fuses let car sit overnight, etc and still no luck. It appears to be in some kind of a subscription update loop but won't stay on long enough to allow me to do anything. The NAV map screen tries to load but never does so I can't try the navigate trick to stop the reboots and the factory reset option is missing from the dealer mode menu. Not sure if there was a procedure problem, bad instructions from Dodge or an incompatibility the software cannot deal with but it's shot at this point. I'd love to get my hands on the 16.12 zip file and try to load it myself but the uconnect site tells me my software is up to date and I can't find it published anywhere. Dealer ordered a replacement radio which will be a refirb, not thrilled about that but fingers crossed it's a good one. Supposedly it will have the latest software on it already, hopefully it won't be missing the air intake temp gauge that some owners have reported.

Not seeing factory reset. Are you referring to settings gear menu or dealer mode menu? I tried reset personal settings but it didn't do full reset, just reverted changes I had made like EQ settings etc while station presets remained. I found a link to a 16.8 download on a Jeep owner's site but need the 16.12 the tsb was reccomending. If anyone knows a site please post. Hard to believe this is truly irreversible, I'm sure when my core is sent back after dealer replaces it the radio the factory will do a reset on it. Thanks again for any info.

My debacle continues. No ETA on when a refirb radio will be available from United Radio and Dodge MVP warranty refuses to authorize a "new" unit from warehouse stock. They said it could be 3 or more months before a refirb can be sent which is totally unacceptable. On the reboot, even after pulling fuse the drain somehow continued to kill battery and after several full discharge cycles the battery gave out and will no longer charge. Dealer tested battery and confirmed bad so I purchased new OEM from dealer and opened case with FCA customer service asking for reimbursement since radio mess caused failure. FCA is declining to reimburse me for battery. Terrible treatment IMHO, I have a 60k car and can't drive it unless I disconnect battery every night. Latest proposal is to have dealer pull my radio and send it out for rebuild and possibly give me a rental car which seems absurd. Mopar warranty and customer service channels not working out for me very well.
