Blaze won't start

[AmzyAmy]

My Blaze battery was being drained so quickly (have an iPhone 6) and it died and won't switch on anymore. 

The green light is still working but it doesn't charge or switch on. No buttons work and it won't synch with my phone

Please clean the contacts

Then Do a Restart

Also See this thread for charging best practices. If you are not charging it correctly you could be damaging the battery

It's great to see you around @AmzyAmy and @WendyB thanks for stopping by.

I would like to know if the instructions provided by our friend worked? Is your tracker working properly now or do you still having issues with it?

Hope to hear from you soon.

Same problem here... No screen but light works. Problem appear after device run out of battery, niw it charge but don't turn screen on anymore.

Troubleshooting :

1) contacts cleaned (charger and device) 

2)hold back button for 30s (nothing happens)

Obs: device charges normally and green lights are always on

Sorry @Felipek7 holding in the back button should not do anything, try a restart by holding in both the back and select buttons (lower right)
