Kimfly Mate 9 (SC7731) is a budget 5-inch Android device mainly sold in emerging markets under OEM/ODM branding. Users have reported issues such as constant bootloop or being stuck on the Kimfly logo after a failed OTA update, random app crashes (“unfortunately, app has stopped”), rapid battery drain, network drops, touch lag, Play Store sync errors, and failed charging (especially after charger port issues). Some units are bricked after using generic Android tools.
Flashing this official SPD V01_20170822_6.0 firmware is the best-known solution for reviving a dead device, clearing boot and system errors, solving battery drain and camera/Play Store bugs, and restoring your Mate 9 back to factory performance.
