I documented my last EM7565 update on OpenWrt here:  
[https://lists.freedesktop.org/archives/libqmi-devel/2019-November/003166.html](https://lists.freedesktop.org/archives/libqmi-devel/2019-November/003166.html)

Ignore the first part with the debug output. Look for the prompts (root at wrt1900ac-1) to find the 3 necessary commands. File names, versions and device names must be changed of course.

Note in particular that my QDL device is ttyUSB4 because I have 4 other USB serial ports. Yours will probably be ttyUSB0, but this must be verified by eg looking at dmesg after resetting the modem.
