We've updated nevo firmware to the latest version, so there might be some problems while updating if wrongly operated (see how to update the firmware for Android). Once it failed, the watch seems to be not working: no matter which button you pressed, there is no LED or vibration; or even the blue LED is flashing, it can't be paired with the phone. Here is what you can do if you are an Android user. 


Preparation work:


1. a sufficient battery is necessary.

2. make sure there is no other Bluetooth devices expect for your phone (Bluetooth on).

3. the app "Nevo" is on the latest version.


steps 1:  app setting-->forget watch-->app will restart; or delete the app. it's the same thing.

steps 2: while reinserting the watch battery CR2025, hold the 1st and 3rd button at the same time. You will see all the white LED flashed once. If so, you are doing it right; if not, please take out the battery and try again;

steps 3: turn on the app, on the third screen "turn on the watch bluetooth", long press the screen( the nevo watch image), app will scan the watch on DFU mode, and popup a dialog to tell user to do OTA, press "YES" and restart the update. 



This is for when nevo has failed the updating and was in DFU mode. In this case, you may find nevo in phone BT settings defined as "Nevo_DFU", and not as the normal name, like "Nevo8AA".
