This is a Qualcomm MSM8916 based router with USB stick form factor and ~384 MiB RAM, ~2.4 GiB flash. It has 3G/4G (UMTS/LTE) connectivity, WLAN, and LAN-over-USB. It runs Android and gives ADB shell access.
The webinterface does barely allow any customisation, the ADB shell does not give root access.
The device can reboot into fastboot mode and into Qualcomm's EDL mode.
I would like to have a free, customisable firmware on this device.
