Despite all the fantastic help & support found here and on other sites, I had quite a few headaches setting up my cable & software for my V400. So, since I've gone through it once, and have things more-or-less working now, I figured I'd post a little step-by-step primer for other noobs. I've got a Cingular V400 and I've set this up both on WinXP home & professional systems.
CABLE -- check out the cables on ebay. CDROM/cable package not required, USB cable only is OK. So far as I know, everything on the CDROM can be downloaded for free. Most ebay stores seem to charge almost nothing for the cable, but tack on $5 for S&H, so maybe consider getting 2 or 3 cables (as spares or for work or for your significant other or whatever). Note -- there have been many reports that FUTURE DIAL and RADIO SHACK cables don't work for this, you can generally identify them because they have a little black box in the middle of the cable that does something tricky & bad to the signal. Other 3rd-party cables are generally OK, they should just look like a plain black wire with a USB connector on one end and the special Motorola connector for your phone on the other end.
SOFTWARE REQUIREMENTS --
All software listed here can be downloaded for free from ************, either in the "Drivers" area or "Programs" area. I'd recommend downloading all this software to one directory (perhaps c:\downloads\motorola), this may make searching for drivers a bit easier. . . . Download the following:
1) P2K Driver (Vxxx phones are all "Motorola platform 2000" based) - the basic USB driver for your phone.
2) Motorola Product Support Tool (PST 6.7) - powerful software. Loads a bunch more drivers. You need to use this once to change a setting in your phone to load Java apps (games!)
3) Motorola mobile Phone Tools (mPT) - provides an interface to Outlook and Express (but not Palm?), also includes it's own computer phone book. Allows transfer of jpegs & sound files between phone & computer.
4) Midway - use to upload games (Java .JAD files) to your computer.
SOFTWARE INSTALLATION --
1) P2K driver -- required to get your cable working. Once you extract the files (just drop them in the same directory you downloaded to), plug in the phone. Should automatically launch the "detected new hardware" wizard. DON'T let Windows search for the driver, point it to the folder with P2K. If set up correctly, you should be able to go into Control Panel, select Phones and Modems, locate the Motorola Modem (your phone looks like a modem to the computer, and can actually be used as a wireless modem if you have a dial-up account), and check that basic communications has been established using the "Query Modem" function. See the motclub guide for additional details (note - the motclub installation guide is in the "Guides" area, not in the "Drivers" area!!! That's not real clear on the Drivers page where you download the driver).
2) PST 6.7 -- Running this program once will again launch the "new hardware" wizard and will set up a bunch of drivers. In addition, to configure your phone to allow uploading Java games, you'll need to use this program to make a one-time setting change to your phone (which makes the "LOAD JAVA APPS" command appear on your phone). See http://viciousglitch.tripod.com/motorola.htm for details -- one thing that's NOT clear there, though, is how to determine what Com port your phone's using -- you can determine that from the Control Panel modem window mentioned above under step 1 (P2K). Careful with this program -- you can also seriously screw your phone up with it!!! Don't be scared of running PST, but don't do too much playing around and random button pressing here either! Same thing with the "new hardware" wizard here -- just keep pointing it to the directory where you downloaded all this software, DON'T let Windows choose the driver for you automatically.
3) Motorola "mobile Phone Tools" (aka "mpt"). Pay attention (!!!) to the installation instructions here:
3a. Download & install version 1.23c -- But DON'T RUN IT OR CONNECT YOUR PHONE!!!
3b. Download & run the version 2.16 update. Run the update.
3c. DON'T CONNECT YOUR PHONE YET!!!
3d. Run mpt. When requested to register, just hit "register later". Don't worry about registering, once you run it you'll find out that it's already registered. DON'T CONNECT YOUR PHONE YET!!!
3e. Mpt should eventually pop up a connection wizard. Click "USB". Sit & stare at your screen for a while as it sets up communication with your phone.
3f. Try running Live Update (found under the settings menu in mpt). Didn't work from behind the firewall at my office, but worked fine from home. As of today, there appears to be a version 2.19a and 2.20 available. I don't see much difference between them and 2.16, but you might as well get the latest software if you can, I guess.
3g. Wait for the display on your computer to STOP saying "Initializing. . ." before you play with the program. ALSO -- look for a little red alarm icon on your computer, if you see that it means there's bad communications going on. RECOMMENDED that you turn your computer's sound on (if you can), the drivers give a little beep when the phone connects, and a different beep if communications drop.
3g. Computer-phone connections generally don't seem to be very stable. Try disconnecting/reconnecting your phone, or power cycling it. Communications do seem to improve after a while (maybe that's just wishful thinking).
HELPFUL LINKS -- http://************/
Has all software you need, along with guides, games & music downloads, heavy-duty technical information, etc. In Spanish and somewhat technical, but THE BEST resource for Motorola phones even if you've never heard a word of Spanish in your life.
Have at it FET! And anyone who wants to copy/modify/add to this, whatever, feel free! It's yours!
Maybe someone could add some more stuff on mp3's (I think I heard 48kbps at 44kHz mono, or was that 44 & 48?), as well as ringtones (although FET already covers that pretty well on his site), wireless, etc. I haven't had a chance to play with that stuff yet!
Maybe we can get this into a sticky or a FAQ? I don't know how to do that either!
One more piece of software that you may want to add to the list is P2K File Manager. Software is very handy in locating some of those unwanted ringtones, gifs and videos that are hidden by default when using MPT.
I downloaded P2K Driver and P2K File Manager, but still it doesn't work... I looked at Divice Manager, and I can see Motorola USB Modem under Modems, though.
I always get an error, and need to close P2K File Manager.
It looks like pst.dll is causing the problem.
And I don't understand "check that basic communications has been established using the "Query Modem" function." part.
Do I need to install PST 6.7 to run P2K File Manager???
I just got my v400 car kit and phone tools kit with data cable-- but the dumb thing wont transfer music to my phone keeps saying "unidentifiable information, delete?" What is this and how do i fix it !!
Guess what u have done a gr8 job ..... ......but i was wondering if this thin works for the V300 as well......as i have a v300........man i need a reply for this ......and i am in front of my computer till i get a reply .......
i'm having a serious trouble with minee.... because i've installed it in the past and itz worked but now i needed to reinstall and the windows wouldn't detect my phone enough that windows doesn't popp up the "detected new hardware" dialog....
when i plug in and then turn off and on my phone,
the windows shows "detected new usb device"
then it pops up "usb may not fuction properly" and nothing gets setup or anything. i've tried editing the registry and installing the modem driver by itself but it ended up with "Vid_22b8&Pid_0005" when on motoclub.com my v400 should be saying "Vid_22b8&Pid_4901". also when i right click on the modem and look at properties... i'm missing the "Rev_0001" that is suppose to be in the hardware ID
someone please help, i've been trying to fix it for 2 whole day....
