How to unlock (open line) Huawei E153-u1, E153-u2, and E153-u3

Okay you have this Huawei “redbox” kit from Globe, Sun, or Smart. Well as it is, its understood that it is SIM-locked to the network provider. But how about if you are on a tight budget, and want to unlock the 3G modem instead? With this tutorial, you will be using one dongle for the three 3G internet providers.

The steps are very simple, if you just follow it to the dot. I tested it on my Huawei E153-u2 (SIM-locked to Globe), and it now works very well on any SIM and Mobile Network.

Proceed with caution, and use the tutorial at your own risk! And again, follow the tutorial as described! If its not described, don’t do it! I already get feedbacks of bricking modem. Mostly its because of not understanding the tutorial. So please read it first before performing it.

Step 1. Backup the device’s data (NVItems). Download the QPST software here. Install this software; you will need it on the succeeding steps.

You will need the backup file in case something went wrong

Step 2. Locate your device’s port. Go to Control Panel, Device Manager. Click “Ports”. You should see something like the one below

On this example, its COM4. It depends on your machine! Check it carefully!

Step 3. Run the QPST software from your Windows programs menu. Click Start, All programs, QPST, Select “QPST Configuration”

Step 4. Add the port located from Step 2, to the running QPST program

Its COM4 on this example. Check your own COM port!

Step 5. Uncheck “Show Serial and USB/QC Diagnostic Port Only” to reveal all COM Ports. Highlight the device’s port.

Its COM4 on this example. Check your own COM port!

If you done it correct, you will see something like

It starts with SURF6246 in Philippines
I suggest that you DO NOT CONTINUE if you are not sure that this will work for you or your modem does not start with SURF6246. There is no turning back if the modem is bricked and I am not responsible for that.

Step 6. Highlight the COM Port from Step 5, click “Start Clients”, and select “Software Download”

Step 7. Click the “Backup” tab. Before commencing, make sure the Port: portion of the menu is pointing to the correct COM port. On the QCN File:, just click the browse button, and select the directory/folder you want the NVItems data to be saved. Click “Start”

Its COM4 on this example. Check your own COM port!

Step 8. Download Huawei Flasher here, and the Huawei E153 Downgrade firmware here.

Step 9. Start the Huawei Flasher Program. Connect your Huawei E153 dongle, and close the 3G modem dashboard (the modem application to connect to internet) if it’s open. Wait until your modem is detected in the Huawei Flasher program.

Step 10. Click “Select Firmware” and point it to the E153 Downgrade Firmware file from Step 8. You should see “6246_K” on the Model: portion of the menu

Make sure the MODEL box will show 6246_K if its not like that then stop at this point to prevent bricking your modem

Step 11. Uncheck the “06.bin” on the menu. It is needed so that you won’t get error message when downgrading the modem. Click “Flash modem”, and select “Normal mode”. Wait for the pop-up box for 10 seconds before clicking OK. Then leave the software and modem for the downgrading process. At the end of the process, you will get an error (on the 08.bin) but it’s normal. Wait until it is fully finished

Count 10 seconds before clicking OK! Don’t unplug the modem or use any program while doing this operation!

Now, you can use any SIM you like on your unlocked Huawei E153 3G modem!

If you want to restore…

For restore procedure, perform Step 1 up to Step 6, but on Step 7 select the “RESTORE” tab instead

  1. hi , i used your post to unlock my unlocked huwei modems following your steps carefully and at the downgrading process that message is pop up and said this step could kill your modem forever and sense i have nothing to use i take the risk and click yes to continue then after the hole process is finished the flasher software reset the device and it say reseting device and i heard that first sound of usb devices resetting then i UNPLUG the device and replug it again and the device become undetectable for windows anyway i think i should wait while the resetting complete or as the flasher said it killed the device , but i don’t accept the idea of the device is dead and can’t be repaired or recovered again i am looking for a way to debug this device again and i have the NVram backup that you mentioned , so is their is any possible way to get this device again and without any hardware interfaces or cables as JTAG or Mkey dongle and these thing because i am in a place that NO programming devices is available specially for USERs like me , the device is Huawei E153Eu-1 and it was customized firmware for etisalat company in Egypt and i just did upgrade it their and when i try to unlock and use it here in sudan it become very hard to break forever i used some of temproary unlocking methods until the 10th try then i reset it many times but all of that was not comfort and i don’t know why exactlly they put all these restricts while the communication companies haven’t any problem to use their devices or another if you already subscribed to their network service and pay for it , so as this story become bigger i have to mention that this post is very usefull in it get me deeper into telecom world and i heared of these software before but i wasn’t know how to use and if there is no way to fix this problem without any additional piece of hardware i just had a little amount of ACKNOWLEDGE about this and the thanks is for you .

    1. I did not instruct to unplug the modem. I do not yet know of any step to recover bricked modems, I will just make an article then if I have one.

  2. i have different issue after doing this tutorial,it brick my Modem, my modem is detected on windows but there is no signal when i put any sim card, the problem that i see is that it remove the IMEI number of my modem thats why it cant have a signal,im looking for answer to resolve this problem hope any one can help…

    also i found this medusa box that can repair this modem but its to much price cant afford it :(

    1. If you don’t get the usual error popup then your modem is now unlocked. And, after that, try find in settings “GSM Only” then change back to “3G/WCDMA Only” so you can debug if the signal is the problem (maybe you have poor signal).

      It did not changed or remove my IMEI, only the “Serial Number” set to “Unknown”.

      There is also a probability that you have a custom firmware, so you need to reflash it using the original firmware (Google for your network firmware update).

      Try to restore your modem, using the backup data (Step 1 to Step 6 ONLY). On Step 7 click RESTORE instead of backup.

      I’ll update my article to warn the users about being careless. Just follow the procedure by the dot.

  3. i have tried your software and it is so amazing it actually works for my usb modem..thank you..but what about the celphones of huawei like mine is ideos i tried to configured it using the qpst but there is no detection in the port when using device manager..can you help me with this? thanks and more power….
