SyncUp Tracker firmware

I'm wondering the same thing. I received a message in the app (once) that Firmware Version 679 was available, but none of my Trackers seem to be updating. I've even left them plugged into a constant USB power source for multiple days and still on 677.

Firmware update keeps failing for me too and the battery doesn't even last long enough without update so it's almost useless. I ended up with 3 devices because the sales person told me they don't cost anything which was not true, and when I tried to cancel the phone numbers attached to the devices, I was told to pay more than $100 for the devices or keep paying the monthly charges for the phone numbers for 3 years minimum to pay off the cost of the devices. This is a rip off. Anyone interested in starting a class action lawsuit?

I think I can answer everybody's question here. All right so there's a couple different generations of the sync up drive Not sure if you have the original generation because I ran into an issue where something happened I can't remember for the life of me but T-Mobile replaced it and ended up giving me the new generation and I've never had the problem you guys are discussing. So ask T-Mobile to replace your device with the newest generation and you should be okay that's the only thing I can think of to do
