S series fails to check for update and when manually downloading it, it's a file without extension, which if I had .zip manually I can then extract the .bin, however firmware verification process fails.
There's something fishy with the file.

Sandro Oliveira After upgrading fimware through the web browser, (auto-upgrade), system no longer boots.
All leds light up and stay that way.
Ping to both defined IP address and default one fails.
Reset button does nothing.Anyone knows any recovery procedure? This model has no serial port.

Oscar Colka Sandro, Yeastar has a backup firmware install in the box.
Try follow below steps to enable the backup firmware:
1. Power off your S series PBX;
2. Press the reset button and hold the button, and power on the S Series PBX;
3. After you hold the reset button for around 15 seconds, you should be able to see the LED lights are blinking with Greed, Red and Yellow color. If you see this, you can stop press the button and the backup firmware should be enabled properly.
