How to flash Huawei E1550 3G Modem

September 15, 2010 Neil

A step-by-step guide on how to update the firmware (flash) of a Huawei E1550 3G Modem.

After I posted the How to unlock Huawei E1550 3G Modem, I received a lot of inquiries through comments and emails asking for a detailed procedure on how to flash the modem.

I tried to flash my modem’s firmware but it almost fried the unit. After an hour or so of Googling, I finally was able to completely flash the modem’s firmware.

Warning

Flashing/Updating the firmware of your 3G modem is risky and may cause the modem to stop working. The procedure below has been tested on only ONE Huawei E1550 3G modem. No further trial was performed using another unit or other models of Huawei 3G modems.

Update/Flash at Your Own Risk

Overview:

Flashing is a procedure wherein the firmware is re-programmed or updated. Flashing could also mean loading the same firmware to the device.

I loaded firmware version 11.608.12.04.21 to my Huawei E1550 3G Modem. After the procedure, the modem failed to detect network signals. It took hours of scouring the net to find the solution; I used Hyper Terminal and reactivated the connection.

I used dc-unlocker to check for information needed later on the steps.

The Tools:

  • Firmware for Huawei E1550.

You can download the firmware from several sources.  I use Firmware Version 11.608.12.04.21 because I read from the Huawei forums that the later updates have problems with 2G network.

E1550 Firmware

The firmware is essential. If your provider have a downloadable firmware, try that first before using firmware you find on the net.

The link provided is for Singapore StarHub’s website where you can download the firmware for E1550.

The dashboard is the program that you use to connect to the network. This is the same dashboard that your provider tweaked to add subscriber-only restrictions and functions. This will replace the files in your data card.

The dashboard is said to work with any provider AS LONG AS you have the correct information like APN, Number, etc of your network provider.

As mentioned above, after the firmware update, the modem stopped detecting 2G networks. With the use of Hyper Terminal, we’re going to remove that restriction

GUIDE

Update Dashboard

This is a fairly straightforward procedure.

  1. Plug the data card (Huawei E1550 3G Modem) to your computer.
  2. Run the downloaded dashboard software.
  3. Select “I Agree”.
  4. Start the update.
  5. Once finished, unplug the modem from the computer.
  6. Restart computer.
  7. When the computer has completely loaded, plug the modem. (This will trigger the installation of new drivers.)
  8. Once the installation is complete, restart the computer.

Flash the Firmware

Another straightforward procedure.

  1. Connect the data card (Huawei E1550 3G Modem) to your computer.
  2. Run the downloaded firmware.
  3. Accept.
  4. Wait for it to finish.
  5. Complete.

Reactivate Network

  1. Start HyperTerminal (Hypertrm.exe). (If it asks you for the location, hit Cancel > Yes.)
  2. Enter a name for the connection. (Any name will do.)
  3. Select the correct COM port where the data card is plugged into.
  4. Click Connect.
  5. Type:    AT^SYSCFG=2,2,3fffffff,0,2
  6. Hit Enter. If it’s successful, you will not receive any confirmation. Otherwise, you will see an error message.
  7. Close the connection.

That’s all. You may now try to unlock your Huawei E1550 3G modem.

  24. Zailer

    it was so simple and very well explained esp with the direct linking … I dont know how to THANK YOU for the effort you have put … in searching understanding and finally taking time to explain it so well … it took me 3 hrs trying different things stated on web but unsuccessful …. finally i ended up here (actually your first blog) and got all the tools then did it a try …. its working perfect.
    feedback.
    i didnt put any sim card during the process (cos i never had an idea card with this)
    those two RESTARTS are necessary ( i was lazy but i had to do it eventually )
    when i updated the firmware .. dc unlocker said status UNLOCKED (previously it was SIM Lock status : Locked (customized firmware))
    attempts left was wrong code 10 left 0 …but still after update it was reset to 0

    i went straight with the docomo sim … without the third step and its working fine got connected.
    pls tell me if its necessary
    thanks a lot :)

Could it be just me or does it look as if like some of these remarks appear like coming from brain dead visitors? And, if you are posting at additional online sites, I would like to follow everything fresh you have to post. Could you make a list of all of your shared pages like your twitter feed, Facebook page or linkedin profile?
