After that modem open only one port ttyUSB0 and not work.
Please help.
Dear Apanas,
Thanks for your inquiry in Quectel forum.
For your issue, it have not upgrade the firmware successful.
Please upgrade it again to have a try, and double check whether the connection cable is stable enough, and remove modem manager to have a try, you also can change to use Qfirehose tool to upgrade it to have a try. Thanks!
Please make sure the port is USB DM port, and have not occupy by any other application, confirm the USB cable have no any issue, you can try to change another USB cable or another PC USB port to test again. Thanks!
Yes, port is USB DM port (no others only one is open by modem), no any usb cable, insert direct in PC port and already try all ports on PC - result the same (error timeout)
Thanks.
If that, it is really hard to say where is the issue. The last method you can try is to connect USB_BOOT to VDD_EXT to force the module enter into emergency download mode to try again. Thanks!
Dear Apanas,
Thanks for your updating. I am glad to hear that the modem recovered successful.
Sorry that the support@quectel.com have not contact you, i will emailed internal to push them to answer you. Sorry that bring any inconvenience for you. Thanks!
You are as user and dpdk is located in /usr/sbin/ - so system binaries -
to bypass this and also solve for other time, this issue, edit ~/.bashrc or ~/.bash_aliases
add line: alias dpkg=‘sudo dpkg’
and next time (after next login*) your username will user dpkg will use it with sudo in front
.bash* files are initialized at user log in
In all Ubuntu releases default username (first username created when you install OS) is already added in sudoers group.
You can check this by typing: id - at the end of the outputed line you will see group ‘wheel’
