Before the app writes the firmware to the modem, the app resets the modem (i.e. My E153 is originally on COM19 according to Windows. So, if you get the com ports wrong (as I did many times), it should not screw up your modem.
Even though the app doesn't work exactly correct, the author does fail-safe checks before doing any work on the modem. So here's the trick, at least for me.and also the good news. N_PORT is port that program will use for read infoĭ_PORT is port that program will use for flash modem If you have problem with com ports edit "ports.ini" file I started dissecting the error before I finally noticed the author's comments in the left hand window: All that error is saying is that the automatic modem detection function of your 3G modem is going to fail and you'll have to specify the COM ports manually in the ports.ini file (found in the same directory as the exe). But, if you're unlucky (like me), you'll be presented with this error upon launching the application:Ĭlick Continue, otherwise, the application will quit.
If you're lucky, you can probably eliminate some of the steps that I encountered. This tool is a little buggy, but at the end of the day, it gets the job done. You will also need the firmware update file: But, this method only requires Huawei Flasher Application 1.6 found here (I believe the earlier version of the flasher didn't have the NV Items Backup): There are other similar posts that mention the QualComm QPST app as well as the Huawei Flasher. However, this is a temporary unlock and will basically lock again after the modem is unplugged and plugged back in again. So, this blog is to hopefully save you some time.įor a while I used Huawei Modem Unlockerv 5.8.1b. I finally figured out how to unlock it permanently, but it basically took me all night. However, it was locked to another internet provider. (Normally I use my Nokia C5 in this case, but I seem to be getting a lot of disconnects lately from it that I don't get from the 3G/HSDPA sticks.) I had a spare Huawei E153 lying around that was not as fast (max 3.6Mbps), but still good enough for what I need. Recently my 3G modem USB dongle/stick died and I didn't want to buy another while my main one was in repair for one to two months.
