==Switching back to Ethernet mode==
To put the dongle back to Ethernet mode you will need to connect the dongle to a computer in order to send it some commands via a serial terminal
#Open gtkserial or another serial terminal (or simply echo the following AT commands to /dev/ttyUSB2) (or maybe another dev/ttyUSBx):
ATZ
Disconnect the modem from the computer and reconnect it to the FireBrick
===What mode is it in?===
On a linux system, if you run <syntaxhighlight>lsusb</syntaxhighlight> you'll see something like:
Bus 002 Device 030: ID 19d2:0016 ZTE WCDMA Technologies MSM
The <syntaxhighlight>0016</syntaxhighlight> is the mode:
*1225 – Default Mode. Available USB Mass Storage Device with CD-ROM and card reader. Corresponds to AT+ZCDRUN=9+AT+ZCDRUN=F
*1403 – Operating Mode. Available RNDIS adapter and Mass Storage Device. Corresponds to AT+ZCDRUN=8+AT+ZCDRUN=F
*1405 – CDC Ethernet Mode (the one we need). A mode similar to that described above (1403). Included in Linux after starting usb_modeswitch c default settings.
*0016 – Download Mode. Under the name of ZTE., but simply a mode where available diagnostic port and two command (analog modem port and PC UI devices Huawei). Corresponds to AT+ZCDRUN=E
*0076 – "real" Download Mode. Includes a standard for devices running QC methods.
