Convert Huawei E3372h-153 from HiLink/router-mode to Stick/modem-mode [ UPDATED 2016-09-02 ]

This is updated version of my original post. I purchased additional modem that's externally identical to old one but had different serial port USB ID (USB\VID_12D1&PID_1442&MI_00) missing from earlier driver pack causing original instructions to fail. I have also included latest Stick-mode firmware 21.200.07.00.805 I've found and corrected some incorrect information on original post.

Modern Huawei USB LTE modems can be used in two very different modes. Default is HiLink mode where it functions as router doing NAT and other nastiness much like more traditional 4G routers connected over WLAN or Ethernet. Unsurprisingly default mode is HiLink, but luckily it can be changed to Stick mode getting rid at least one layer of NAT and related issues.

Actually there's also third mode which is subset of Stick, instead of native NCM interface it uses legacy PPP over emulated serial port. This can be sometimes useful with older routers with USB port but you won't be able to reach full speed in this mode.

Internet has plenty of information on how to do that. As it often is not all of that is true. Most interesting bits are also written in Russian. Despite huge improvements in translations from Google Translate it's still a bit of hit and miss.

Following these instructions will also resolve Error Code 19 and "brick" with Error Code 13 (rapidly flashing green led). Which is also why some steps may seem bit pointless at first. Feel free to skip them and then start again from beginning when Mr Error #19 and Mrs. Error #13 bite you. :)

You'll need Windows PC for this. I've used 64-bit Windows 7 and Windows 10 PCs myself.

If you've tried this before coming to here I'm sure you've seen those "open http://192.168.8.1/html/switchProjectMode.html" instructions. Those are for older models like E3372s and won't work with E3372h.

Hold tight!

  • Visit either one of these sites to calculate device specific "Flash code" based on your IMEI and write it down. Depending on current firmware running on your device you may or may not need Flash code later. Better be safe and get one ready so you don't get stuck.
  • Download and extract this ZIP that contains required tools, drivers and firmware images
  • Install "[1] Mobile Broadband HL Service" by running mbbServiceSetup.exe
    • Installs RNDIS driver
    • Installs service to switch from CD emulation to RNDIS (like usb-modeswitch on Linux)
  • Install "[2] Datacard Driver" by running Driver_Upgrade.vbs
    • Installs serial port drivers (including FcSerial needed by some devices)
  • Insert E3372h-153 with HiLink firmware to USB port
    • Preferrably directly to PC, avoid cheap chinese USB extension cables.
    • Open Device Manager and verify that RNDIS interface is present under Network adapters
    • Open command prompt and "PING 192.168.8.1" to make sure HiLink firmware is running
  • Run "sw_project_mode.cmd" from "[3] Switchmode E3372h" folder
    • This will enable "PC UI" serial port required for firmware upgade
    • Wait until you can see it under Ports in Device Manager
    • "curl: (56) Recv failure: Connection was reset" error is expected and should be ignored
  • Run "Update_WEBUI_17.100.06.00.03_Hilink_V7R2_9x25_CPIO.exe" from "[4] Huawei E3372h WebUI"
    • This updates user interface but doesn't touch rest of the firmware.
    • If you have Error Code 13 this will fix it. Code 13 ("Authentication failed") is caused by failed attempt to flash firmware resulting in Error Code 19 ("Download failed").
    • See HUAWEI_Module_Firmware_Upgrade_Guide_on_Windows_V100R001_01(5).pdf for complete list of error codes.
    • Wait until WebUI update is complete and you can ping 192.168.8.1 again.
  • Run "sw_project_mode.cmd" from "[3] Switchmode E3372h" folder
  • Run "E3372h-153_Update_22.180.05.00.00.exe" from "[5] Huawei E3372h-153 HiLink FW" folder.
    • This upgrades (or downgrades) your HiLink firmware version. You may need Flash code from one of those calculators to do this.
    • Wait until HiLink update is complete and you can ping 192.168.8.1 again.
  • Run "sw_project_mode.cmd" from "[3] Switchmode E3372h" folder
  • Run "E3372h-153Update_21.200.07.00.805_Universal.exe" from "[6] Huawei_E3372h-153 Stick FW" folder.
    • This finally changes firmware from HiLink to Stick. You may need Flash code again.
    • Wait until Stick update is complete. You can no longer ping 192.168.8.1 and RNDIS adapter has changed to "HUAWEI Mobile Connect - Network Card".
  • Run "putty.exe" from "[7] Putty" folder
    • Find serial port name from Device Manager, for example in case of "HUAWEI Mobile Connect - PC UI Interface (COM15)" port name is COM15
    • Click Serial on right hand side of Putty screen and type COM15 or whatever your port is.
    • Click Open on botton of Putty
    • Type ' ATE1 ' without quotes, you won't see what you type and DO NOT try to use backspace. If you did it right you got ' OK ' as reply. Ignore ^RSSI etc. lines you might also see.
    • Type following commands one per line to see info about your device and verify connection works. 
      • ' ATI '
      • ' AT^FHVER '
      • ' AT^VERSION? '
    • Get current SETPORT value by typing ' AT^SETPORT? '. You might want to write these down if you ever want to revert back to defaults. Mine was ' ^SETPORT:A1,A2;12,1,16,A1,A2 '.
    • Set new SETPORT value by typing ' AT^SETPORT="FF;12,16" ', this is claimed to disable CD emulation and modeswitch requirement but actually it only disables unnecessary ports appearing after modeswitch. So you still need automated switch from CD emulation to WWAN with "Mobile Broadband HL Service" or "usb-modeswitch" in Linux.
    • If you want to keep PPP support for example for older router with USB port use ' AT^SETPORT="FF;12,10,16" ' instead. Remember that you won't get full speed with PPP.
    • Reset modem by typing ' AT^RESET '.
    • Close Putty now.
  • Done. 

Your E3372h is now in stick mode, presents itself as NCM device that's compatible with Windows Mobile Broadband feature and also with huawei_cdc_ncm under Linux. You don't need 3rd party mobile tools on Windows. This means to connect Internet use built in features of your operating system, stay away from "Mobile Partner" etc. 

If you prefer keeping HiLink why not root it? :) If you don't root it someone else probably will given Huawei track record on security... There's excellent writeup and step-by-step instructions in English from Ivan. Modeswitch tools are also from him. 

Rest of files were collected from links found on lteforum.at4pda.ru and 3Ginfo.ru.

P.S. You can get E3372h-153's from Ebay for 29€/each including shipping from Latvia. Downside on these cheap ones is broken locking tabs on top cover. This is because they're LMT branded and were superglued shut with LMT SIM card inside.

  11. Hi, nice walk through, but I'm stuck trying to flash the WebUI in step 4, getting the #19 error. My stick is on firmware 22.200.15.00.00 and WebUI 17.100.05.06.965. Update Wizard is not asking for any key but stops working when it is just about half way. Stick restarts and after a while I get error #19. Rgds Sven

    2. I have the same problem (firmware 22.200.15.00.182, WebUI 17.100.12.00.182), step 4 fails with error #19.
      Starting from beginning won't help, either.

      Also, the stick doesn't respond from IP 192.168.8.1, but from 192.168.1.1, which can be modified to cmd scripts.

    3. Thanks for the procedure and tools.
      Unfortunately I have same problem here as mentioned by Gar and Olli.
      While loading WebUI firmware, it stops working when it is just about half way, and then error 19 pops up. Also I see that the "PC UI" port disappears from the Device Manager right after Web UI firmware loading has started.
      And I also get the error "curl: (56) Recv failure: Connection was reset" after running "sw_project_mode.cmd". IP is 192.168.1.1 not 192.168.8.1, but as was mentioned before, I also changed it to the script.

      Dongle is DNA branded E3372H-153 and my PC has Windows 10 64bit.

    5. hi. For anyone having the same troubles as me. Recent firmwares are locked against updates. But there is one way to do it: http://4pda.ru/forum/index.php?showtopic=582284&st=8400#entry40683419
      It worked fine for me and i finally have the configuration i want together with openwrt. But it requires you to open the device. Google translate helped a lot. Let me know if there is a step you don't understand. For example i didn't remove the battery because i didn't find one, i simply disconnected and reconnected the device.

  14. No (AT^SETPORT="FF;12,16"), you should be able to add it with proper AT^SETPORT=.

    4. I managed to get Hilink away from E3372s-153 - how ever Dongle is not any more working on Windows workstation.
      My usecase is to use it with WLAN router and dongle is working now well with it.
      So I didn't find out what caused the problem that it does not work in windows.

    ReplyDelete
  22. Because this site helped me a lot I would like to share a tiny bit of knowlage that also helped me.
    I had Error 13 and/or Error 19, both with very often flashing blue led on the modem. That means modem hanged in "download mode". Basicly it means that modem is a "brick".. To do anything with that you have to "unbick it".
    Download stript below, unrar files. Next check a COM number of your modem in hardware manager in your Windows and run a script from a command shell with parameter "COMXX" where XX is a number taken from your hardware manager. I always found two coms assigned to my modem, the second one from the list worked with the script.

    https://www.dropbox.com/sh/szyiili6kyua5u8/AACC-4BPfSGX7FEyFPqABlDoa/exit_download_mode_E3372h/exit_download.rar?dl=0

    After that try to flash modem by using :
    "E3372h-153_Update_22.180.05.00.00.exe" from "[5] Huawei E3372h-153 HiLink FW" folder.

    from THIS SITE!!! I tried about 10 other updaters and only one from this site worked. I'm not really sure why, but is seems that e3372h-153 are in at least two subversions and custom roms from one can make an error on other one and you finish with brick state modem (error 13/19).

    Thank you and good luck!

I wonder if theres a later version of this: "E3372h-153_Update_21.180.01.00.00.exe" from "[6] Huawei_E3372h-153 Stick FW" and if there is, would it be possible to just replace that file with a newer file?

  26. Hello, thanks for great how-to, I successfully converted my e3372h to modem mode.
    There was only one problem in my case, after switching mode in step number 3 there was no serial port interfaces available.
    It seems that in step 2 there are some missing drivers, after typing "fcserial.sys" into google i downloaded missing driver from link:
    http://www.mediafire.com/download/39p188qk2bfu563/Huawei-Debug-and-Project-mode-drivers-FcSerial.zip
    Then I opened Device Manager and clicked on unknown huawei_mobile device and selected driver update and after that the serial port was detected.

  30. I needed the 3g/4g modem to disable the cd emulation but leave the SD card enabled (because I have a really tiny OpenWRT router that has 8 MB of flash, with this enabled I can expand its firmware features using the sd card in this device).

    this is the command I used (also leaving modem open) AT^SETPORT="FF;12,1,16,A2"

    Other interfaces are explained here

    http://forum.mikrotik.com/viewtopic.php?t=89458

    Quoting relevant part here just in case
    -------------
    found theese settings using AT^SETPORT, and AT^GETPORTNAME:
    AT^SETPORT="initial_mode;normal_mode"

    map:
    1 - Mobile Data Modem (MDM)
    5 - GPS interface
    6 - control interface
    12 - PC UI
    10 - modem?
    16 - NDIS
    A1 - Virtual cd
    A2 - TF card reader
    FF - Dummy (disable modeswitch when using this as the initial mode?)

  31. Thank you for your great tutorial, it was very easy to follow.

    I've used Windows 10 (64 bits) and, for some reason, Putty was unable to connect to the COM port. I even tried running Putty as Administrator, but still no luck. So I booted in my Ubuntu 14.04 (also 64 bits), installed gtkterm and issued the following command under root account:
    gtkterm -e -p /dev/ttyUSB0

    This way you don't need to set echo on with the command "ATE1". After this, all the AT commands were successful.

    Meanwhile, my e3372h works in NCM mode under Windows, but not in Ubuntu. My kernel version is 3.16.0-67, maybe I need a newer kernel version, or are there any drivers I should install?

    For now I've enabled the PPP mode to keep compatibility with Linux.

  32. Hello, Does anyone here have b315s-936? I think they are related to HiLink.
    Because when we flash/update the firmware to 21.313, when in USB Mode, it's not detected in COM Ports(PC UI) anymore unlike the low versions. As a result, we can't send AT commands as well as return to previous firmware version.

    I followed this tutorial hoping to get back the PC UI interface but sad to say it's not working. :(

    Any other way to detect in COM Ports or to send AT Commands?

  45. I bought the said stick from DNA for 50€ yesterday (20160809). It had a firmware with AT^NVWREX and AT^NVRDEX disabled, and it refused to update either WEBUI or the real FW, even it goes to debug and project modes when POSTed the right XML data. I only got to error #16, 'Failed to switch the download mode'.

    Solution was to follow "krnlyng liar" advise from 4pda.ru via google translate. The solution required shorting a pin inside the modem (screws are T5) to ground for two seconds and simultaneously connecting it to computer USB port, then flashing a transitional fw and then the final stick fw.

  47. Hello, first of all thank you for this tutorial, it worked fine for me with my Huawei e3372h. I disabled Hilink mode and converted it to stick-modem mode because in router mode with Hilink I got a "dialing error" when I tried to configure the wmail.vf.es APN on it which works perfect in my smartphone and in another USB modem like Huawei e173. In stick/modem USB this APN (wmail.vf.es) works perfect and I am able to connect to Internet without problem with the native Windows mobile network manager. The problem is the connection is at less speed than in Hilink mode so...¿Anyone knows how to return/revert/back to Hilink mode from stick/modem mode please? I've been looking for it on 4pda.ru via Google translate but I am not able to understand that "bad" translation. Thank you again and see you soon.

  48. I made a mistake. I changed IP from 192.168.8.1 to something else (192.168.1.3) but now it does not respond at all, also there is no internet connection any longer (2 green blinkings every 2 seconds, before change it was ok). I can no longer login to the HiLink menu. Is it ready for trashbin or are there any ways to recover this unit? I did that before I found this internet page, I wanted to remove "router mode" and convert into only "modem mode". But since I can no longer access my modem, I want to recover it. Surprisingly there is no "reset button" on this device so no way to start over when do mistake.

  50. Hi,
    I have made a huge mistake I guess. I wanted my E3372h-153 to have hilink mode and tried flashing the hilink firmware. But my modem came in stick mode and does not have the webui installed. So right now I can't access the web ui nor flash back the stick firmware since there is no com port... Even the mode switch will not work since the web ui firmware is not present.. Any ideas how I can save my modem?

  53. Stupidily I tried to update the WebUI in E3372h-510, got Error Code 19 and now device blinks in green. Tried to use download_mode_exit but it just restart and go again to blinking. Then, I tried to use E3372h-510 downgrade (to 21.110.99.02.00) but I get Error Code 13.

    After that, it returns current versions:
    Firmware: 22.200.13.00.916
    Dashboard: WEBUI_17.100.12.00.916

  55. Worked perfectly on my E3372h-510 from Movistar Argentina!! Thank you very much, now my router TP-Link MR-3020 recognize it!!

    Just a comment: I had to manually download de file "E3372h-153Update_21.200.07.00.805_Universal" for step [6] because the zip "Huawei_E3372h-153_HiLink-to-Stick" has this file "E3372h-153_Update_21.180.01.00.00" wich didn't work for my router. You can download the file here https://routerunlock.com/?wpfb_dl=1501

    Thanks again!
