Thank you so much for the project.

Just want to assure that your code works fine. It took me several hard hours try to figure out why #17 and #18 only solve half of my problem.

My E1750 (which I got about 10 years ago) is locked to one network provider. Running your code will spit out broken pipe trying to connect to ttyUSB1 and ttyUSB2.

I want to share my solution here. Hope it helps others. My guess is that some providers, like mine, will ask Huawei to immediately disconnect the device if not suitable sim card is detected.

==== THE WRONG WAY ====

I plugged in another provider's sim card.
Plug the usb in.
Run usb_modeswitch.
The computer will still "see" E1750 but there is no way your code will be able to write to the device. When I run

func@func:~$ dmesg | grep tty

[ 186.516118] option1 ttyUSB0: GSM modem (1-port) converter now disconnected from ttyUSB0

You can clearly see that ttyUSB0 has been disconnected.. Sad!

==== THE CORRECT WAY ====

First plug a valid sim card from the original provider to keep the device connected to your machine.
Do all the usb_modeswitch and any other stuff you need to do to load your device.
Execute the unlock script. Everything should be running as expected.

I am writing this comment to you using the unlocked E1750 dongle via the initially 'unsupported' sim card.
Kudo to you.

My OS is Ubuntu 18.04.2 LTS
My dongle is E1750 fixed Viettel carrier
I have install python2.7, python3 (default) and python3.7.3 as well as pySerial

I totally don't know about Linux. I just learn to unlock my modem

Thank for your help

Sorry because I'm not familiar with GitHub and Linux. So may be I miss some useful post when I looking for

P/s: I also wish to know about Linux OS and I saw that GitHub is very useful

Thank,

Answer 3 · 2019-06-29T09:38:46.000Z

As said, the error states that python cannot access the dongle. Either you (i) do not have sufficient privilege to access the device, or (ii) the device disconnected itself when it cannot find a valid sim card.

To fix the first error. Just run the command using sudo prefix. You don't need to use su but su should work just fine.

To fix the second error, you need to put a valid (preferable active) 3/4G Viettel sim card in first. Your dongle most likely disconnected itself when a Viettel sim card is not found.

Mine is also a Viettel branded dongle. What I am saying is yours should work.

Testing port /dev/ttyUSB1

This may be because you need to run this program as root.

I inserted a 4G Viettel Sim, then verify by turning off wifi, and connect internet using that Viettel SIM card. After I have verified the connection of my dongle, I disconnect dongle and re-connect the wifi. The result is not improved.

May be I installed the python and pyserial improperly?

What is the output of lsusb?

Did you implement the #18 fix?

Answer 6 · 2019-06-29T14:56:03.000Z

Hi function1983,
The output of lsusb:

I really don't understand much about # 15,16,17,18.
I did: copy the codes from # 18, replace to the unlocker.py downloaded from the main page

def identifyPort():
print "Trying to find which port is the active modem connection."
print "Please be patient as this can take a while.\n\n"
for p in glob.glob('/dev/ttyUSB*'):
try:
print "Testing port " + p
ser = serial.Serial(port = p,
timeout = 15)
ser.write('AT\r\n')
activity = ser.read(5)
if activity == '':
print "\tNo activity\n"
ser.close()
continue
except:
print "\tError, This may be because you need to run this program as root.\n"
ser.close()
continue
else:
print "\tActivity detected\n"
ser.close()
return p
return ''

Please teach me about:

usb_modeswitch
catch exception (how to catch, what is it? How to manually catch?)

I also try:

serial.Serial(port='/dev/ttyUSB1', timeout=15)

The result same:

Looks like your computer has detected the device, which is a good sign.

Your dongle could act either as an usb storage device or a WAN dongle, but NOT both. usb_modeswitch tells the dongle to switch between the two modes. Default is usb storage.

#18 fix is to tell python to ignore any error message when sending AT command to each usb device and just keep iterating without crashing to terminal after failing the first usb device. CODE HERE. But first, run dmesg | grep tty after usb_modeswitch to see if your device is listed as connected there. Please include the output if you still face the issue.

Answer 8 · 2019-06-30T05:50:05.000Z

I replaced the codes from SHOTbyGUN to original unlocker.py then perform:

lsusb
usb_modeswitch
dmesg | grep tty
sudo ./unlocker.py

Here are what I did:
