Welcome to SA Tech Help
It is just hanging on the boot logo and will proceed not further. I have tried hard resetting but no go. How do I re-flash the firmware afresh. I expect this should be able to resolve the issue if it is indeed a firmware issue.

  3. Install the MediaTek Preloader USB VCOM drivers as per the tutorial here
  4. Launch the SP Tool from the extracted folder
  5. Click on the Download tab
  6. Click 'Scatter-Loading' > browse to and locate the scatter file from your extracted firmware files
  7. Connect the Mobicel Onyx to the computer via a compatible USB cable without the battery
  8. Then click on the Download/Start button and then install the battery so computer can detect and connect to its system
  9. The flashing process should then start with progress bars and you should get a green cycle with a white tick and the text 'Download OK' when the flashing is completed. At which stage you can safely disconnect the your Mobicel Onyx device and power it on for a re-setup.
