A verified update is signed with a private key known only to the OEM. The EW6800’s bootloader checks the signature before flashing. You can manually verify using OpenSSL: ew6800 firmware update verified

openssl dgst -sha256 -verify public_key.pem -signature firmware.sig firmware.bin

If the output says "Verified OK," your update is genuine.

Before initiating the update, operators must ensure compatibility between the current configuration and the new firmware image. sha256sum ew6800_fw
