Step-by-Step Flashing Guide for Calme 4G MegaPower (MTK CPU)
Follow these instructions exactly as written to successfully flash your MediaTek-powered Calme device:
- Extract the Files: First, download the firmware zip file and SP Flash Tool. Extract both of them into separate, easily accessible folders on your computer's desktop.
- Install Drivers: If you haven't already, install the MTK VCOM USB Drivers. This is crucial; otherwise, your computer will not detect the phone in powered-off mode.
- Launch SP Flash Tool: Open the extracted SP Flash Tool folder, locate the
flash_tool.exefile, right-click on it, and select Run as administrator. - Load the Scatter File: Once the tool is open, click on the "Scatter-loading" button on the right side. Navigate to your extracted Calme 4G MegaPower firmware folder and select the text file ending with
_scatter.txt(e.g., MT67xx_Android_scatter.txt). - Verify the Partitions: After loading the scatter file, you will see a list of partitions appear in the tool. Make sure the flashing mode is set to "Download Only". (Note: If "Download Only" fails, you can carefully try "Firmware Upgrade". Do not use "Format All + Download" unless absolutely necessary, as it wipes the IMEI).
- Initiate the Flashing Process: Click the green "Download" button at the top of the SP Flash Tool interface. The tool is now waiting for your device.
- Connect the Phone: Power off your Calme 4G MegaPower completely. Press and hold the Volume Up and Volume Down buttons together, then connect the phone to your PC using the USB cable.
- Flashing in Progress: Your computer will detect the phone, and a red progress bar will appear at the bottom of the SP Flash Tool, followed by a yellow bar showing the actual flashing process. Release the volume buttons once the yellow bar starts moving.
- Completion: Wait patiently for 5 to 10 minutes. Do not disconnect the device during this time! Once the process is 100% complete, a green circle with a "Download OK" message will pop up on the screen.
- Restart Your Device: Safely disconnect the USB cable from your phone. Remove the battery (if removable), reinsert it, and power on the device. The first boot may take up to 10 minutes, so be patient.
Congratulations! You have successfully installed the fresh stock ROM on your Calme 4G MegaPower.
