In the "Download" tab, click the Scatter-loading button. Navigate to your firmware folder and select the text file ending in _Android_scatter.txt .

Before starting, ensure you have the following components prepared:

Choose Download Only or Firmware Upgrade . Note: Avoid "Format All + Download" unless absolutely necessary, as it can erase your IMEI/NVRAM data. Start Flash: Click the Download button in the tool. Connect Device: Power off your Qumo Quest 474

Unzip the SP Flash Tool and the firmware package into separate folders on your computer.

Flashing a stock ROM typically wipes all personal data, so back up your files if the device is still functional.
