I ask for help to create the firmware for my device.
I bought a router based on Quectel E25-EU, the seller said that Openwrt is there, as a result, there is simple Linux without a web interface, only Telnet control that does not suit me.
The device has 128 MB RAM and 128 MB Flash.
Can someone tell me how to collect? I’m ready to thank if they help to make the device working on openwrt!
