So can I really write AT+QLINUXCMD to my USB LTE Modem over tty-over-USB and execute arbitrary shell commands on the modem's internal linux installation as root

  If I remember the talk correctly, then yes. But it was said that there are several distinct firmwares…

  If your USB LTE Modem is a Quectel (or maybe Sierra Wireless) MDM9615 based modem, yes. Otherwise, no.

  It's still present even in the latest EC20E firmware EC20EQAR02A09E2G from 2016-09-24: ynezz@ntbk:/opt/devel/flexisbc/quectel_ec20/EC20EQAR02A09E2G$ grep QLINUXCMD Binary file 9615-cdp-recovery-image-9615-cdp.yaffs2 matches Binary file dsp2.mbn matches Binary file 9615-cdp-usr-image.usrfs.yaffs2 matches Edit: formating

    Would Sierra Wireless 313U be a good candidate?
