[Puck] Unable to connect. Device became undiscoverable from both Macos and Android

Yes, then I suppose I have the latest bootloader. I actually ordered this one last week on 17th July. I bought it from shop.espruino.com: Invoice No.: ES-00224 Order ID: #301; if that helps.

Steps I followed.

1. Battery out
   
2. Press and hold the reset button
   
3. Insert the battery. Green LED lits
   
4. Release the button immediately, the Green LED brightens up.
   
5. I used my Android phone with nRF Connect app to scan.
   
6. But still, I'm not able to see the device on the app.
   
   

Does this mean that the Bluetooth trans-receiver is damaged?
