Help on downgrading to v2.16.0

Hi. I tried to downgrade my Reach RS+ to v2.16.0 from v2.17.3. I followed the steps on manual reflashing of firmware and it was successful. But every time I start my device for the first time it requires me to update to v2.16.2. I dont want to update to 2.16.2 because it has a bug on “Lora not connected”.
