Before proceeding, please note: Flashing firmware carries risks. If you flash the wrong version, experience a power outage during the process, or interrupt the installation, you can "brick" your device (render it unusable). Proceed at your own risk. EVPAD devices generally use an OTA (Over-The-Air) update system which is much safer than manual flashing. Authentic firmware files are not always publicly listed
