Tutorial: USB DUN with "Wireless Modem" app on HTC Mogul
 

Description:

The "Wireless Modem" application lets you connect your mobile device via a USB cable to a computer, and dial-up (DUN) to your phone's EV-DO data connection. This allows you to access the Internet on your computer via your cell phone (tethering)!

It seems Sprint/HTC neglected to give us the necessary files to get the "Wireless Modem" (from the good old pre Windows Mobile 6 days) application working. This is a howto on getting "Wireless Modem" setup and running. I've attached the missing files needed at the bottom of this post.


Tested with:

HTC Mogul running original v2.08 Windows Mobile 6 ROM with Windows XP Pro SP2 (32-bit), and Vista Ultimate Edition (32-bit)


Why is this better than other methods?:

You may ask what the purpose of this method is when you may already have a working solution such as Internet Sharing, PDANet, or USBModem? Good question, it's:

Better than PDANet because:

• It's free
• Doesn't rely on ActiveSync
• Can be shared. Since "Wireless Modem" works through a dial-up adapter, on Windows XP/Vista machines it can be shared with other clients via ICS (Internet Connection Sharing). For instance I've connected via my laptop, and shared that connection via a crossover network cable from my laptop to an XBox 360, to let the XBox 360 access the Internet!

Better than USBModem because :

• It's free (Wireless Modem's behavior is pretty much identical to USBModem)

Better than the "Internet Sharing" application (included with WM5 AKU3+) because:

• It's not NAT'ed, you get a public IP with "Wireless Modem". NAT'ed connections are problematic with some games and applications, such as certain VPNs.
• Since it's not NAT'ed there's less communication overhead, resulting in a slightly better latency, and faster transfer speed.

Setup Summary

1. Install the Dial-up Networking through Bluetooth Under WM5 AKU3/WM6 Hack
2. Enable PAM (Phone as Modem), and set it as the default dial-up connection
3. Apply registry changes to (hopefully) disable NAI (tethering) detection
4. Setup a dial-up connection on your client (eg. laptop) device
5. Decompress the attached files and place them in the proper folders
6. Run the "Wireless Modem" app, and start it sharing via USB
7. Connect your device via USB cable to your computer
8. Dial-Up to the Internet and enjoy!

Installing the Dial-up Networking Through Bluetooth Under WM5 AKU3 / WM6 Hack

1. From the Bluetooth DialUp Access folder in the attached .zip file, install WM6_BT_DUN.cab into main memory on your device.
2. After installation, soft reset your device

Enabling PAM (Phone as Modem) Connection

1. You must first have the MSL number for your phone. The MSL unlock code is used for programming your phone yourself, and is unique for every phone. You can retrieve the MSL for your phone by using the GetSPC application. It's essentially a keygen that calculates what the MSL should be from the hexadecimal ESN (case-sensitive). You can download it from HERE. Otherwise you can call Sprint technical support, tell them you're a developer, and you need the MSL number for your phone.
2. Open up your dialer, and dial in ##3282#
3. A window should open, select Edit
4. Enter in your MSL from step 1, and press the OK button (left softkey)
5. Select the line that has the value MIP_Mode under the Item column
6. Press the Menu button (right softkey) and choose Edit
7. Change the value from from Mobile IP Only to Mobile IP Preferred
8. Press the OK button (left softkey) and soft reset when it tells you to.

Setting PAM (Phone As Modem) as the default dial-up connection

1. Go to Start->Settings->"Connections" tab
2. Select the "Connections" applet
3. On the "Tasks" tab, select "Manage existing connections"
4. On the "Modem" tab, make sure the "Phone as Modem" radio button is selected
5. Press "OK" to save your changes

Disabling NAI/Tethering Detection (hopefully)
Using a registry editor, navigate to the "HKEY_LOCAL_MACHINE\Software\OEM\WModem" key, and set the "CheckProfile", "Multi-NAI" and "WModemDUN" DWORDS to a decimal value of "0". Remember to soft reset for the changes to take effect.

Note:
The following note does relate to getting the "Wireless Modem" application, but might of interest to those using the "Internet Sharing" application. It seems Sprint is up to shenanigans in regards to tethering for SERO users. Those of you running Sprint ROMs should navigate to the following registry key "HKEY_LOCAL_MACHINE\Comm\InternetSharing" and delete the string value named "Extension". This will allow you to connect to the Internet via the "Internet Sharing" app without the dreaded error 67/authentication errors. Previous to this fix, Mogul SERO users would have to connect to the Internet via another method (such as starting Internet Explorer first) before pressing the Connect button in the the Internet Sharing application.

For the lazy, I've created two Mortscripts (included in the attached .zip file), that apply ("MogulTetherFix.mscr") and, check ("CheckMogulTetherFix.mscr"), that the proper registry entries have been made (both for "Wireless Modem" and "Internet Sharing"). To use these scripts you must first download, and install MortScript from HERE or HERE.


Installing the missing files:

From the attached .zip file, copy the following files:

Wireless Modem.lnk
- Description: Shortcut to Wireless Modem application (Points to "\Windows\WModem.exe" /LAUNCH)
- Place in \Windows\Start Menu\Programs folder on your device

WModem.exe
- Description: The actual "Wireless Modem" application
- Place in \Windows folder on your device (v2.08 Mogul ROM already has this file).

WModem.exe.0409.mui
- Description: English language resources file needed by WModem.exe
- Place in \Windows folder on your device (was missing from v2.08 Mogul ROM).

Setting up USB Modem driver on the computer:

On the Phone device:

1. Make sure you've applied the NAI/detection registry changes described in the beginning of this post.
2. Some say, you should terminate ActiveSync on your device, and terminate ActiveSync/Windows Mobile Device Center on your desktop, before running Wireless Modem, but I skip this step, and it seems to work fine for me.
3. Launch the "Wireless Modem" shortcut.
4. Make sure "USB" is selected for "Connection Type"
5. Press the "Menu" button, and choose the "Start" menu item

For a Windows XP/2000/Vista client computer:

1. Login into Windows PC as a user with Administrator credentials
2. Connect the USB Cable from the Mogul to your computer
3. After a short period of time the Found New Hardware Wizard screen will appear. On my Vista laptop, I let it search the Internet to find suitable drivers. It took a while, but it eventually found and installed them for me.

For those that have trouble getting/installing the drivers, I've extracted them from my machine using DriverGrabber, and put them in the attached .zip under the "drivers" folder. To install them, repeat steps from above, but instead of letting it search the Internet for suitable drivers:

1. Select the No, not this time option and press the Next button.
2. Select the Install from a list or specific location option on the displayed dialog and press the Next button.
3. The Please choose your search and installation options dialog will appear on the screen. Uncheck the Search removable media option, and use the Browse button to point to the appropriate subfolder under the \drivers folder from the unzipped archive attached to this post. After that, press the Next button.
4. The installation will be started and the Hardware Installation warning will be displayed. Press the Continue Anyway button to go on with the installation.
5. After that, the Completing the Found New Hardware Wizard screen will appear. Press the Finish button.
6. The driver installation is now complete and Windows will pop up a balloon with the text "Your new hardware is installed and ready to use".

Creating a New Dial-Up Connection:

For the Sprint CDMA network, the dial-up number is #777, the user name and password are blank.

For a Windows XP/2000/Vista computer:

1. Start the Create a new Connection wizard. To do this, press the Windows Start button, select Connect To, choose Show all connections, and look for the wizard in the Network Tasks area in left of the panel. Alternatively, go into Windows Control Panel and choose the Network Connections item.
2. The Welcome to the New Connection Wizard screen will be displayed. Press the Next button to proceed.
3. The Network Connection Type screen will be displayed. Select Connect to the Internet and press the Next button.
4. The Getting Ready dialog will appear. Select the Set up my connection manually option and press the Next button.
5. The Internet Connection dialog will appear. Choose the Connect using a dial-up modem, and press the Next button to proceed.
6. The Connection Name screen will be displayed. Type in the name of the connection. For example, Internet via USB Modem is good. Press the Next button.
7. The Phone Number to Dial screen will be displayed. Type in the #777 and press the Next button.
8. The Internet Account Information screen will be displayed. Don't enter anything for the user name and password, uncheck the Make this the default Internet connection checkbox and press the Next button.
9. The Completing the New Connection Wizard screen will be displayed. Enable the Add a shortcut to this connection to my desktop for easy connection access and press the Finish button.
10. Now start the Internet via USB Modem dialog by double-clicking on its icon on the Windows desktop and press the Properties button
11. The connection properties dialog will be displayed. On the General tab, make sure the Use dialing rules option is disabled
12. On the Options tab, uncheck the Prompt for name and password, certificate, etc. and Prompt for phone number options, and press the OK button.
13. The CDMA data connection is now setup!

Connecting to the Internet:

1. Make sure you've applied the NAI/detection registry changes described in the beginning of this post.
2. Some say, you should terminate ActiveSync on your device, and terminate ActiveSync/Windows Mobile Device Center on your desktop, before running Wireless Modem, but I skip this step, and it seems to work fine for me.
3. Launch the "Wireless Modem" shortcut.
4. Make sure "USB" is selected for "Connection Type"
5. Press the "Menu" button, and choose the "Start" menu item
6. Connect the USB Cable from the Mogul to your computer
7. Double click/dial-up the Connection you made previously, make sure the connection is set to the right dial-up device (HTC USB Modem)
8. Enjoy!

Disconnecting from the Internet:

1. Disconnect your dial-up connection on your computer
2. Disconnect the USB cable from your mobile device
3. Press the "Menu" button, and choose the "Stop" menu item
4. Press the "Done" button

FAQ:

• My connection seems flaky/slow, how can I fix it?
  
  Don't place your mobile device too close to your computer. If the devices are too close your connectivity could get flaky.
  
  
• By using this will I be charged by my phone carrier?:
  
  Generally, this will incur the same charges as using the Internet on your phone. If you have SERO data plan, and you applied the NAI detection hacks correctly, you should be fine. The only way to be sure the NAI hacks worked, is to look at your next bill. You are responsible for any charges you may incur.

Final Thoughts/Comments:

This should also work for Bluetooth DUN, irDA, and on the MAC and Unix platforms. For the MAC and Unix platforms it's just a matter of locating and installing the correct drivers, and setting up the dial-up connection. If you get this to work on those platforms, please reply, with a copy of the drivers, so that I can update the install package. You might have some luck with the drivers HERE. Also you may want to locate/try the PPC-6700 USB drivers for those platforms. And for hints on how to setup the connection on a MAC/Unix machine, try examining the USBModem manual, as the steps should be very similar.

Changelog:

v0.1

• Initial Release

WOW! Great job. very precise. this is how a tutorial should be written. easy to follow and everything is explained. thank you for your hard work.

a question or two. i use ICS with luv2chill reg hack and never really had a problem (except with activesync always wanting to turn on). how dramatic of a difference will i see if i switch over to DUN?

also, call me optimistic, but i still believe that rev a is coming soon. what effects if any will the rev a upgrade have with a DUN connection? thanks.

Thanks.

The difference will be very small, but we're dealing with slower connections in general, so every little bit helps, especially on the upstream. The main advantage is that it's not NATed which allows you to host server services, if needed, like FTP, Remote Desktop, or run certain games, VPNs, and apps that don't work well under NATed conditions. Anything that requires you to forward a port is problematic when using "Internet Sharing".

I have no idea how DUN will work when Rev A comes out (probably in 3 years), we'll just have to wait and see.

delewaresace,

dude you need to learn how to spell ot go get a spell checker...your post made me throw up in my mouth a little

...another fine example of the american educational system

Was that trip really necessary... Oh, and by the way... you might want to get one for yourself. You have grammatical errors and you misspelled "OR" in your first sentence.

ROFLMAO!!!!!!!!! Yes, I had to say it.

Hay look, it's Gaudere's Law (it's about the 13th one down).

i posted this on my mogul using Opera Mini that does not have spell check or cut and paste. i'll go back and see if i can edit it.

there is a big difference between misspelling and typo's dumbass...get it straight

p.s. no one said anything about grammar..anyway..off the the dictionary for you..first look up mis-spell. then look up typo...WOW they mean two different things!

thank you american educational system

edit: im not usually ever the spelling nazi but I couldn't help myself.
and to the dumbass who said my typo was a mis-spell..get real..we all know what a typo is

I think you mean:

yep that's what I meant and that's how I spelled it..I like the bold addition you made though

edit: I noticed you changed my spelling of grammar in the quote you used. that's not cool

Nope, I did not. I just quoted it before you corrected the spelling.

what a GREAT tutorial, you couldnt have done a better job. it works because im posting from my laptop sitting in my car connected with my 6800 :)

thats funny. and he tried to go back and change it.

and not to totally derail this thread, i plan on doing the wifi hack to use my mogul as a hub. do you think that the DUN hack you have here would affect any settings or screw up anything with that? i can't really see why it would, but i thought i would ask.

Nope, If you're talking about the Internet Sharing over WiFi tutorial, I wrote that too, and have no trouble using one or the other on my Mogul, the files/methods they use are not related at all.

Great guide. Worked like a charm!

when I dial ##3282#, my phone does nothing. I am using the touch dialer. Could that have something to do with it?

Yes, old/non CDMA dialers are known to break debug dial code functionality. If you want a Touch like dialer that works properly on CDMA, use this one:

http://pdaphonehome.com/forums/ppc-6...heme-here.html

With the following skin:
http://pdaphonehome.com/forums/ppc-6...tml#post655902

Tried this on the DCD rom and the codes won't work either. The ##DEBUG one does but not this one. Tried installing the dialer above but it also does the same thing. Anyone know how to do this on the Alltel ROM?

This is my question also...
 

I also tried the above dialer and can't get ##DATA# to work. Anybody know how?

I did some investigation for you guys, the dial code ##3282# just brings up the application EPST.exe with a parameter of ##3282 ("\Windows\EPST.exe" ##3282). I've created, and attached, a shortcut file you can copy to your device, and run, as an alternative to accessing it from the dialer.

Thanks Talyn, that did the trick!

I'm running Sampson's latest WM5 rom with radio 1.47, and I'm stuck on the step of setting PAM (phone as modem) as the default dial-up connection. When I go to start - settings - connections - connections - tasks tab - manage existing connections - modem tab, the only thing that is there is CDMA1X with number #777...there is no "Phone as Modem" radio button. When I click on edit for the CDMA1X, the modem choices are 'cellular line' (what it's currently on), 'bluetooth', 'generic irda' and 'hayes compatible on COM1.' Is there a way that I can make the proper settings?

I tried running through all of the remaining steps in this great tutorial anyway, but when I get to the installation of drivers on my XP machine it detects a generic serial connection, but then can't get an IP address.

Anybody know the answer? Thanks for your help! This forum rocks!

:headbang:

TalynOne, what a great write up on setting up USB DUN! I was confused on the differences and this is exactly what I was looking for. Cheers to you!

This might be of use to those trying to input other dial codes:

I would skip the PAM portion, I think it's more of a tweak than anything. Hmm, there seems to be more more stuff missing on Sampson's WM5 ROM, than the Mogul's WM6 ROM, try importing the attached file into the registry, soft reseting, and see if that helps.

Thanks for all your great help Talyn!

Sorry to be a noob, but how do I import this file into the registry? I'm using PHM regedit, and when I click on tools the 'import' option is greyed out. I clicked on the file but it just takes me into PHM, with import greyed out. Is there a specific place in the registry that I have to navigate to in order to import the file? Thanks for everything - you should go into teaching.

I'm on my Mogul now and can't see a link in the 1st post to DL the zip file. Am I overlooking it, or could you add it so mobile users can see it? Awesome write up by the way!

Also, what does it mean if I get "cannot connect using current connection seting" when I click on the link to DL GetSPC?

thanks for the help, I finally got it working.

Thanks, I actually do teach. Sorry for the delayed response, real life got in the way, and I was hoping someone else might help...

To import .reg files I personally use the Registry Editor in the shareware suite Resco Explorer, works quite nicely.

A freeware alternative is to use Total Commander, which features registry import features. A howto on importing a .reg file is HERE.

You could also use the free CeRegEditor, which is a desktop application that can interface with your Windows Mobile registry, you can get it by clicking HERE.

The only one I've actually used though is Resco Registry Editor...

The mobile version of the PPCGeeks forums doesn't display attachments, and the reason you're getting an error while trying to download GetSPC is because the mobile browser you're doesn't support FTP (the GetSPC is hosted on PPCGeek's FTP server). If you don't have access to a desktop browser to download these files, let me know, and I'll upload them somewhere else and provide a link for you.

Thanks for the great write-up! Incredibly clear; I'm having some trouble getting the driver setup to complete. The first driver I install (manually) is the HTC USB Modem driver, which goes flawlessly. Then, windows detects a second hardware device and I point it to the HTC Diagnostic interface driver. It then pops up a file needed dialog asking for "qcmdmxp.sys" on HTC USB Driver Disk. Is this second driver needed for this tethering method to work? Thanks again.

Try pointing it to your \windows\system32\drivers folder.

I just have to say that these directions worked perfectly. This post in fact comes from my laptop connected to my phone. :D

Thanks for the detailed and concise set of instructions (as well as downloads)!

Are there 64 bit drivers for the USB Modem? I can't get drivers for x64

Tried this today and worked flawlessly. Thanks

edit- nevermind got it to work.

I'm doubting it. I've been searching Google all day long and the only x64 driver I can find is for the TYTN/Kaiser. I'm going to contact HTC and see what they say. Can't hurt to try I suppose.

Help Please1 I 've done everything except I do not see a windows directory on the Mogul so what do I do with these...

Wireless Modem.lnk
- Description: Shortcut to Wireless Modem application (Points to "\Windows\WModem.exe" /LAUNCH)
- Place in \Windows\Start Menu\Programs folder on your device

WModem.exe
- Description: The actual "Wireless Modem" application
- Place in \Windows folder on your device (v2.08 Mogul ROM already has this file).

WModem.exe.0409.mui
- Description: English language resources file needed by WModem.exe
- Place in \Windows folder on your device (was missing from v2.08 Mogul ROM).

I'd like to get the bluetooth connection working too but have not had any luck other than sending picture files from the Mogul to my computer. On my last phone I had a DUN connection on my laptop that would connect via bluetooth on the phone. I'm at a loss on how to get it to work on the Mogul. BTW that connection says it is using com 40. Kind of high but I don't see how to change it.

Never mind, I stumblen on to the solution......

My response:

I would like to thank you for your response.

I appreciate you taking the time to respond to my email. I do find it hard to believe that the manufacturer of the device doesn’t support the necessary drivers to connect the devices to computers. Motorola supplied the drivers for my Motorola Q, Dell supported the drivers for my Axim X51V, HP supplied the drivers for my iPaqs….. Seems a little suspicious to me as I have seen the Vista 32 bit drivers available for the Mogul. Either way, thank you for your time. I will do some more research prior to contacting Sprint as they are as helpful as a man with one leg in an *** kicking contest.

Have a good afternoon.

i used the GetSPC app but when i enter the code, it says that its the wrong code.
