When I connect my phone to my computer via USB, the first time it installs drivers and makes a noise. The drivers it installs are "Samsung Mobile Modem Diagnostic Serial Port (WDM) (COM6)", "Samsung Mobile Modem", and "Samsung USB Composite Device."
However, the device does not show up in Windows Explorer, and if I turn USB debugging on, it does not show up as a device I can debug on.
The device is running Android version 4.0.4 with model number SPH-D710.
I have tried installing the Samsung USB Driver for Mobile Phones, but that does not do anything differently when I plug in the phone.
I have tried with both of my cables and it works with neither one.
I have tried dialing *#7284# and changing USB to modem then back to pda and restarting the device, but that makes no difference as well.
The phone used to be a Credo Mobile phone but last year it was flashed to Page Plus. I'm not sure if this could have made the USB connection to the computer stop working as a USB storage device.
The phone shows up in devices and printers as a modem and USB hub.
Any ideas on how I can get it to work with my computer (Windows 7)? I mostly need it to work for USB debugging which is currently impossible.
Wrong forum, belongs here. I've asked mods to move your thread, sit tight until they do.
Found solution
I found a solution:
I had to change it to AP mode by dialing ##8778#. It was set to CP mode, probably from when I had it flashed. Yay!
Found it in this thread: http://forum.xda-developers.com/showthread.php?t=1956802
Thanks for helping me find the right forum.

Ok so I want to root my epic, there's just one problem... ADB doesn't see my phone. It is listed in my device manager and is showing as working. but when i try and list adb devices it shows nothing. My phone is in USB Debugging mode. I have the Samsung drivers installed. I just cannot figure out why this is not working for me. I have looked everywhere and have been unable to find anything that has helped my problem at all. Tried to upload a pic showing my device manager but i guess i cant yet because i haven't made enough posts yet. Device manager show my device in three different sections one under USB Controllers as SAMSUNG USB Composite Device, One under Ports (COM & LPT) as SAMSUNG Mobile Modem Diagnostic Serial Port (WDM) (COM4) , and one under Modems as SAMSUNG Mobile Modem.Thanks for any ideas.

Try different USB port, switch data cable and also uninstall - reboot- reinstall driver - reboot - reboot phone - try again.
If you are using a laptop sometimes it's flaky. Reboot often and remember that you may have to kill that exe process... Think it was adb.exe a few times and just screw with it until you trick it to work. Trial and error

Ok so I wated a video on rooting samsung epic and one thing that I noticed was that when he hooked up his epic it showed up in the device manager under ADB Devices and mine shows up in 3 other locations. Is this where my problem is... am I just having issues with my drivers?

Turn off any security and uninstall the samsung drivers. reinstall drivers and watch and make sure your phone is detected by your pc. Now run your rooting app.

Hello. I am having the same problem as described above. The Epic is installing as a modem (on my Win7 PC) instead of an Android Composite ADB Interface. I cannot connect at all to the Epic (cannot connect via adb with debugging turned on and it I try and mount the Epic no folders show up on the PC). I have reinstalled the drivers and checked all of my serial ports. Also, I have a Samsung Captivate that works fine using the same system. Incidentally my wife took the Phone into Sprint to get the latest android version and they gave her a hard time cause it was rooted. I think they may have done something to the phone cause I pulled pictures off her phone to the PC last week. Help please!!
OK, so I got the Eipc to work. I still do not know the root cause but here are the steps I took to "fix it":
1) Unplugged USB cable and disabled usb debugging
2) Plugged in phone to USB and selected Mass storage. The drivers were installed correctly
3) Unplugged phone and turned on USB debugging)
4) Plugged in phone and the proper devices were detected but windows hung on installation of a "strange" unkown ADB device
5) Unplugged phone and plugged back into the USB port and all was working!
Hope this helps.
Hi All,
I can't seem to get QPST to work with my Epic 4g (trying to change the PRL). I've followed this guide: http://forum.xda-developers.com/showthread.php?t=898628
The issue is (as far as I can tell), the computer isn't using the correct drivers. I can't get the phone to show up as a com port regardless of what UART/USB settings I try, charging/USB tethering, or USB debugging enabled/disabled.
I've attached two pics from device manager, the first is using USB tethering, the other putting it in Charging mode. I've even tried reinstalling the Samsung USB drivers and manually updating them with the phone connected -- but no luck (it says the best drivers are already installed).
Any suggestions?
Found the fix: need to plug in the phone with PDA/USB selected and switch to MODEM/USB after. Otherwise my computer doesn't even detect a USB connection.
Hi there..
I'm new user for Sprint SPH-L710 from Indonesia
just wondering is anyone can help me with MTP connection issue
I already install SPH-L710 driver plus Samsung KIES to my PC but when in plug in my L710 to PC there's nothing show up on notification bar like others Samsung device that i have (SPH-D710 & Gtab 8.9 P7300) that show option to see the contain of the device but on L710 there's nothing anly charging, & on KIES is always on Never Ending Connecting progress..
already re-install Driver & KIES but the result is still the same cannot connect to PC except charging
but actually my PC can read my device as MOdem & Port Samsung USB Driver plus i can use Odin to Flash new Firmware..
Already try with USB debugging checked or not checked and still have same result..
i'm afraid is the problem with USB setting but when i dial ##8778# (UPST Mode) is nothing happen (on Epic 4G & Epic Touch when i dial ##8778# the option with USB connection when we plug it to PC) cause i'm form Indonesia & all CDMA device have to Flash the number from Indonesia CDMA Operator. i'm afraid when Flash the number (via Modem USB Setting on UPST Mode) the person who did it is forgot to set back the USB connection & the problem is until now i cannot get contact the person..
is there anyway that i can do to fix this issue...??
Cheers
Actually I'm in the U.S. on sprInt and have the same issue, my device is not activated yet.....also on win xp, I can use Odin as well so I can live, hope someone can help you

hey everyone,
first of all this is my first post and im new to this so please bear with me
I just bought a T-Mobile SGH-T889 Samsung Galaxy Note II running on Android 4.1.1 with build # JRO03C.T889UVALJ1
I am having some troubles connecting my phone to my computer via the the included usb cable
whenever I connect try to connect my phone to the computer, it would search for updates to install drivers but it would always say that the driver software was not installed due to no drivers found. from what I understand, they should be Samsung drivers but for some reason, mine says:
Qualcomm CDMA Technologies MSM X No driver found
Qualcomm CDMA Technologies MSM X No driver found
I did several searches on the forums but have yet to find a solution or driver for my phone. please help!
I have looked into this thread but the driver provided for the root kit is for Samsung V 1.5.9.0
Thanks!
Welcome to the forum!
I'd say to try uninstalling any Samsung drivers from your pc, then restart it. Go to the Samsung site and download the latest USB drivers. The ones provided in the kit usually work, and I'm not sure the ones on the site are any newer.
Once that is done, if you are still having problems, try a different USB cable.

I had similar issues all I did was Change to another USB port.
Also I did a complete shutdown of the PC & phone not just a reboot.
thanks for the quick replies
I have tried several times or rebooting both the phone and the computer after installing the drivers but to no avail...
I have also tried changing to all the different usb ports on my computer but still no luck
I will try to find another cable in the house to see if that will work.
Will the samsung usb drivers work though? because i have tried those several times, the ones from the root kit as well as the ones from the samsung website but it still doesnt detect it. Are there qualcomm drivers available?
some other information that I forgot to mention earlier, I am running Windows 7 64-bit
sometimes when I connect the phone to the pc, it would load up this driver --> Qualcomm HS-USB Modem 9004 Driver
but then when i disconnect it, it wont detect it again...
a solution im thinking is maybe i should reset the phone to factory default settings? would that help?
For whatever reason, your pc is not recognizing the phone correctly. Can I ask, have you installed drivers for another phone on that pc in the past? What flavor of Windows are you running? Are you up-to-date? Have you tried disabling your firewall temporarily? Finally, try booting up in safe-mode and connecting the phone. That should let you see what it thinks your phone is when no drivers are installed.

I had a Blackberry before but I had already removed all the software and drivers for it before getting the note 2 and I am currently running Windows 7 Home Premium 64-bit and they are up to date. I will try disabling my firewall and safe mode once i get home.
I re-read the tool-kit instructions and noticed i missed something. Am I supposed to put the phone into download or recovery mode before connecting the USB to the computer (after installing the USB drivers)?
I will have to try that once i get home as well... but I still dont understand why it shows up as qualcomm drivers instead of Samsung drivers
anyways thanks for the suggestions I will let you know how it turns out.
This problem is likely due to Samsung's USB cable, as noted in other threads.
Change the usb cable before trying anything else....
ok so i got the drivers to install finally...what i did was boot the phone in to download mode then connect the phone to my computer via usb cable and it worked...but for some reason it doesnt detect it when i launch the rootkit it does not detect my serial number
If i restart my phone normally, and then try to detect the phone again on the computer it will not detect it and goes back to saying the qualcomm CDMA technologies MSM is missing drivers again...
So the only way for it to detect the drivers is in download mode but i cant seem to get the rootkit to detect my phones serial number

EDIT: another question...so once i have the drivers installed, am i supposed to reboot the phone back normally (not download mode) for it to detect the serial number?
I apologize if this isn't the proper forum.
I had a Samsung Galaxy S3 (The non LTE version) with T-Mobile. I have used the KIES 3 software to backup my phone.
I got a Samsung Galaxy S4 (the M919 model) with T-Mobile.
First, I connected the phone to my Win7 64-bit Home Edition pc with the same Galaxy S3 USB cable. It charges, and I hear the "boo-beep" and Windows 7 says it's installing device software and then comes back and says "unknown device" installation failed. In Device Mangler, it shows up under USB controllers, for some reason as "unknown device".
Okay, so I reinstalled the Samsung USB drivers.
No go
I used the actual S4 cable that came with the phone.
No go.
I have done the debug USB mode. No go.
I have verified that the MTP protocol is used (vs. Camera) and that it's set to MTP+ADB
I've switched back and forth to camera vs. MTP
Windows seems to detect the USB signal in that it knows when it's plugged in and when it's not, but it seems to IMMEDIATELY (and I mean very very fast, like under 1 second) "find" it always as a USB controller -> Unknown Device
So, I've tried my laptop. windows 7 64-bit. Same thing.
I had a spare pc around, so I even reformatted the drive and put a fresh copy of windows 7 on it. Same thing.
I've manually installed the Samsung drivers (without KIES). Still no go.
So I guess my questions:
1) Is there some other method to verify USB port is working properly? (like can you connect it to something else and have it work)? I'm assuming it's good since not only does it charge, but it at least is attempted to connect with Windows 7
2) I've got 2 more cables ordered --official Samsung ones--just in case
3) Can you root and unroot a phone without USB? It seems they all require USB drivers, and ODIN to work. I ended up having to manually backup the S3 via GCloud or whatever to get my stuff transferred over.
Oh, I also have an SD card in the phone.
Yes, I tried unmount it, and even removing it, rebooting, etc. Still no go.
I am trying to find an XP machine to see if that works any better.
thank you.
