AT&T MiFi 2372 Generic firmware

Updated 2012/Nov/6 - Give a nice thanks on the blog if this helps. Thanks :)

Only hardware version less than 1.3. Read at end for versions 1.3 and greater.
This will automatically unlock your MiFi. No need for tools like dc-unlocker or the Novatel sim unlock tool.

*Generic: 
Be sure and take any SIM/microSD out while flashing it..

*The default Wifi Password is 12345
*The default login pasword is admin

*AT&T DATA ONLY SIM uses the apn
broadband
no username/password or auth.

*AT&T 3G / HSUPA
I had to go to internet -> settings -> network technology -> 3G -> apply and then battery pull to get the card to recognize 3G.

iPhone had 3G so I had just battery pulled it, but it came back up with the same issue. So I forced the MiFi with the above instructions and all is well now.

The card is getting about .25Mbps more than with AT&T firmware, on a continuous basis.

Email me jason.sands @ the-regular-gmail-com-domain and I will attempt to help you. Contact a tech friend for face-to-face help first if you don't know what 7z, zip, iso, and/or sha1 are.

  7. First you will need these drivers:

    Be sure and take any SIM/microSD out while flashing it..

  10. So mine must have been a later stocked unit because it was locked. I called ATT and got a code and then followed the procedure here http://forums.att.com/t5/Wireless-General-Device/Novatel-MIFI-2372-Unlock-Question/td-p/3247021

    CP from above link...

    Preparations:

    Obtain a SIM card from a carrier other than AT&T
    Remove the battery and note down the IMEI
    Call AT&T Wireless customer service and request your free subsidy code (10 digits)

    You need Novatel's MobiLink 3 software package suite to unlock the MiFi. No sketchy unlocking software necessary, nothing to buy if your device has been out of AT&T service for more than 90 days. There are two ways to guarantee that you obtain the proper MobiLink3 software package tailored for the MiFi 2372.



    METHOD 1: Search for the ISO filename directly

    20418676.Novatel.Multi-Product.001.iso (available in a ZIP archive)

    METHOD 2: Locate and download the Novatel MiFi 2372 generic firmware package

    20418764_MUU_MiFi23x2_FW5.26.2_ML3.00.57_NvtlGeneric_v1.2_pkg.exe
    Run it, make sure a window pops up, but DO NOT FLASH YOUR DEVICE'S FIRMWARE TO THE GENERIC VERSION
    With the program running, navigate to C:\Windows\Temp\MUU and locate the ISO file there
    Abort the upgrade process and close the program

    Extract contents of the ISO using an appropriate program, e.g., 7zip.

    LiteAuto.exe - run this, it should silently install device drivers, if you haven't already
    Installer.exe - run this next, this should install MobiLink 3

    The actual unlocking process:

    Now put a non-AT&T SIM card into your MiFi and plug it into your computer via USB WITHOUT a battery inside the MiFi.
    Run the MobiLink 3 software, it should say say that your device is network locked
    Enter in your 10 digit subsidy code--the dialog window may say that you have 0 attempts remaining, that's normal, enter in your code anyways
    Once accepted, your MiFi will restart. It's now unlocked!
