RuuviTag Pro is dead

App says the battery is too low to operate. Replaced the battery a few times today, and there is no response from the device. No lights. Is it dead? This is the Pro with the black case that has been out in all kinds of weather and dirt attached to my vehicle… What is the tiny pushbutton for? I see no reference to it anywhere. Still, pressing it does nothing.

Hi, sorry for the troubles. Please send a picture from inside the device circuit board to email Push button can be used to change firmware to bootloader mode when updating the firmware.
