Warning: The MediaTek MT6580 chip in the Cosmos V6 is notoriously unforgiving. A power failure, incorrect USB driver, or using the wrong Flash Tool version during this process has an extremely high probability of causing a “hard brick.” This means your phone will show zero signs of life—no vibration, no LED, no boot logo—essentially becoming a dead piece of hardware with very limited recovery options.

How to Flash the Firmware
To install this firmware on your Hotwav Cosmos V6, you must use the SP Flash Tool, as it is powered by a MediaTek MT6580 chipset.
- Download the firmware file and an older, compatible version of SP Flash Tool (v5.16xx is recommended) on your PC. Install legacy MediaTek USB VCOM drivers.
- Extract the downloaded ZIP file. The crucial “MT6580_Android_scatter.txt” file will be inside the extracted folder.
- Open SP Flash Tool, load the scatter file, and select “Firmware Upgrade” or “Download Only” mode.
- Ensure the phone is powered OFF. If it’s stuck in a bootloop, remove and reinsert the battery for a few seconds.
- Click “Download” in SP Flash Tool and connect your phone to the PC via USB. The tool will detect it and start the flash process automatically.
