3. Open “2502 firmware update tool” folder, double click “Flash_Tool.exe”, Check “Scatter/Config File”,then choose firmware update file, then check “Download”. After check “download”, connect S3 with computer, but make sure S3 is power off. During burning time, the data will keep updating, it is normal, don’t worry.
