Hoping for some assistance before putting in a product repair or replace request.
I have a pair of altos both the app and the glasses are on the newest firmware, one day they were working and the next they won't turn on. I've seen other threads about this but I've done some troubleshooting on my own and am very confused!
When you plug them in (tried multiple cables and power bricks) the LED turns full white, pushing the power button allowed me to connect the device to my phone (Samsung Galaxy a51 also newest firmware/software) they work and play music, phone has the glasses battery at 100% but once you unplug them they go dead, can't turn on no status led at all. So obviously not water damaged or anything like that. Is there a way to hard reset the glasses or roll back firmware manually? It very much seems like an issue with the battery not the actual device itself.
Thanks in advanced!
