Huawei E3372 LTE GSM Modem in Stick Mode

Hi There,

I have done this successfully following this guide: http://www.0xf8.org/2017/01/flashing-a-huawei-e3372h-4g-lte-stick-from-hilink-to-stick-mode/

The steps are quite easy.

1. Open device and short the pins & attach to computer

2. Run balong utility (no need to compile as mentioned in the article) available here https://github.com/forth32/balong-usbdload

Command is: balong-usbload -p (COM port number-just the number e.g if COM4 you just need to put the number 4 not COM4) usblsafe-3372h.bin

This will put the stick in a special mode where you can then flash firmware as below

3. Flash firmware with balong flash utility here https://github.com/forth32/balongflash

Firmware available here: https://www.lteforum.at/mobilfunk/firmware-versionen-hi-non-hilink-e3372h-inkl-mod.2691/

Command is: balong-usbflash 3372h-153_UPDATE_21.180.01.00.00.BIN if your device is not a 153, do not worry after flashing this firmware you can then upgrade to the specific firmware you need from lteforum site above.

You just need the BIN file not the *.exe

Upon completion you will have a stick only device with original huawei firmware.

Hello,

I successfully flashed my E3372h (rev. 21.200.07.00.805) using this method and it works perfectly under linux Ubuntu.

But, I can't make it work on Sophos XG85 (SFOS 17.0.2 MR-2).

As soon I click on "Connect", it tries to connect and lost connection with modem. Next tries always fails since modem is not seen anymore by XG.

Here is my network.log

Anyone can help ?

Thanks for your answer but it does not help.

I still have a pppd error.

What firmware version is the modern running?

Here is an extract of mdev.log

Manufacturer: huawei
Model: E3372
Revision: 21.200.07.00.805
IMEI: 861821035707675
+GCAP: +CGSM,+DS,+ES

It is version 21.200.07.00.805

I try to downgrade to 21.180 but without success.

Do you think it can be the cause ?

Maybe I did not set up my connection properly.

Do you use PPP or DHCP ?

I change Modem Port to Serial 1 instead of Serial 0 and it's a little bit better since Sophos does not lost anymore connection to the modem.

However, PPP daemon still die with error 16 and so, no connection is established.

During firmware upgrade, I do some modifications with command AT^SETPORT.

Can you give me the result of command AT^SETPORT? on your modem to see if I have the good configuration.

For now, I have : ^SETPORT:A1,A2;12,1,16,A1,A2

I would connect the stick to a windows computer

Download this http://download-c1.huawei.com/download/downloadCenter?downloadId=94325&version=378649&siteCode=in

Configure the connection and if it works then you know you are looking at an issue with SFOS otherwise you might have the wrong firmware for your device (remember firmware is region specific, although some/most will work globally)

When I connect the stick to a Windows 7 computer, it's only seen as Storage USB Device but no COM port is added.

I don't understand why since it works perfectly on a Ubuntu computer.

I will try to flash another firmware.

Can you give me a link to the exact BIN file you use ?

I try different things on Windows but my Stick is not seen (no COM port) except when I plug it with short pin method.

This is really strange since I have no problem on Linux : ttyUSB devices are created and I can connect on 3G/4G.

Any idea of what could generate the PPP error 16 on SFOS ?

Don't know why but now it works, I'm connected.

However, IP parameters are strange and no traffic goes through the connection.

On WAN Link Manager, status is Down since it can't ping the gateway (10.64.64.64)

I've had a couple of instances where I need to unplug and plug the dongle back in. I have raised a support ticket with Sophos and it has been escalated to the devs apparently.

I find that if you reboot the appliance the WWAN1 connection does not work correctly until the USB modem is unpluged and plugged back in. Seems it needs a cold boot to work.

I'd say its the driver that is implemented in SFOS and that it does not boot and detect switch the device into the right mode.

I agree with you about this problem of modem detection at boot.

Most time (not to say all the time), I need to unplug and plug back the modem for Sophos detects it.

But for now, my problem is different : the modem is detected and the PPP connexion is ok but I have no traffic on my connection (can't ping the gateway).

I think I will open another thread about this.

Hmm not sure about that one

When your connection is up, do you have, like me, a netmask which is 255.255.255.255 ?

And does your WWAN Link Manager show the green point ?

Mine stay red since it can't ping the gateway 10.64.64.64.

Hi Vincent,

Sorry for the extremely late response the answer to your question is YES I do have a netmask of 255.255.255.255

Also I have had another issue where after a hard reboot or power outage the WWAN1 connection will not re-establish and it says that the USB modem is not identified, I have fixed the problem by running the following command in the console.

console > system cellular_wan set modem-setup-delay 15

I had to run this command twice for some reason, second time it worked

Thanks for your answer Damian.

In fact my modem is now correctly detected and the connection is established.

The problem is that no traffic passes over this WWAN connection.

I can't even ping the gateway 10.64.64.64.

Do you have an idea why ?

Hi Vincent,

Is your issue resolved?

Cos I also want to try this huawei 3372h on my sophos XG.

Thanks,

Nikole

Yes the issue is resolved for me. I have three sites with just 4G connections and they are using this setup. Rock Solid so far.

Hi Damian,

 How are you? :)

Can give me a draft/list of what exactly have you done to make this work? From flashing the dongle firmware up to the things needed to configure / commands to run into the sophos.

Appreciate your help. :)

Nikole

Hi Damian and Nikole,

Unfortunately the problem is not solved for me.

I gave up and bought a Huawei B525 4G router which is ethernet plugged into my Sophos.

This is not the solution I prefer so I am also interested in detailed explanations for running the Huawei E3372.
