I’ve been lurking this forum for about a week looking for solutions. I have a CF-53 which came with an EM7305 installed and has mostly worked fine, once I got my Windows installs to behave.
I recently purchased a used Lenovo EM7455 as I would prefer a CAT6 modem. Obviously, this didn’t work and I have spent many hours over the last week messing around with various Ubuntu bootables and terminal emulators but finally I managed to open the ports for COM and Modem, change the PID/VID and flash generic firmware. Everything looks good and I’ve been pleased to get this far…
…but it still shows “No Service” and cannot connect.
Could anyone please suggest what I should now try?
Many thanks in advance.
