Tmobile SyncUp Tracker not connecting

About a week ago the battery died on this device. Since charging it I have not been able to reconnect it.

When holding the power button for about 5 seconds the lights will blink red yellow and green for about 5 seconds then stop and display no light. Then when pressing the power button after that will show a quick yellow flash then nothing.

The app continues to say the device is offline.

Any help would be great, thank you!

Well I just got a tracker and they couldn’t get it turned on and replaced it and after two days still not connected. Fully charged but I just get a green and red light then nothing benn through two techs now waiting for a call from the escalated tech. Will keep posted 

I’m having the same problem. Did you ever figure out what the problem was?

going on two months or more now and my trackers still arent working. T-mobile even replaced them and they wont connect. We tried on 3 different phones and nothing. I think their network is permantely down.

I am having exact same issue, battery went dead 1 week ago and now it will not connect even after fully charged and rebooted. I have two of them and they are both not connecting.
