I tried uploading firmware “V4.8.308.4145708_zZW128_e5351ea_DSI0177” to my Dusun gateway “DSGW-040-7” and now it stopped working.
I don’t have the appropriate firmware for DSGW-040, and since it was on an older firmware 3.x I decided to upgrade it. Now it’s not accessible over the network.
I installed those devices at a remote location, now I need to make modifications to my default firmware and add new default mqtt broker, username/password, and other settings.
First, I need to know what files to make modifications on in order to get default device certificates, mqtt configurations, LTE settings done.
Then, once I make those settings changes I want to repackage the firmware. Do you have any guides to unpacking, changing and repackaging the firmware?
Finally, once the firmware is packaged, I want to deploy it on a URL and then push the remote Gateway to fetch and update its firmware from that URL.
