[Q] Laptop won't recognize phone

my computer does not recognize my epic anymore. I have the required drivers for it , but it keeps on popping up as an unknown device. I also made sure usb debugging was left unchecked. I have been trying to connect for a few hours now but still no luck.

What OS are you using on your laptop? If it's windows go to control panel and your programs add/remove (will vary depending on windows version) scroll down to "Samsung USB drivers" and click "uninstall", then reboot. Go to here and download the most recent usb drivers again. Plug in your phone, then install the drivers.
Post your results. Most likely it is not your phone, its a driver that has become corrupt on your laptop. Other possibilities are a bad USB cable or port on your phone.

Have you tried a different USB cable? Did you make any changes to your phone or PC just before it stopped recognizing it?

I had to use a usb hub with a power source for my laptop to see the phone.
Dell D620
Samsung Epic 4g

same thing on my pc. I keep getting USB Mass Storage Device Failed Error Code 10. started happening after the first push of froyo. im running Windows 7. very frustrating.

Epic thread revival!
I'm having a similar issue with my Epic. Both my laptop and desktop will recognize my phone as "Samsung CDMA Technologies" However, I can't do anything with it except charge. What's particularly bugging me is
A) Wired (USB) Tether won't work
B) Can't mount SD card through the phone
Laptop Specs:
Windows 7 Ultimate 64bit
Linux Mint 11 64bit (I'm having the same problems with Linux)
Phone Specs:
Epic 4G (SPH-D700)
Syndicate ROM Frozen 1.2
EG22 Moden
Genocide 2.0 Kernal
Here is what I've tried:
Toggled USB Debugging (both on and off)
Used Premium Micro USB cable in addition to stock cable
Uninstalling and Reinstalling drivers
used different USB ports
rebooted phone and computer
It should be worth noting that my phone seems to think everything is a-ok. Wired Tether app doesn't report errors, and when I mount SD card, there is no error either and the phone proceeds with the "USB storage in Use" message. My computer (regardless of which OS I boot) seems to think my phone doesn't exist, unless I'm doing admin type of things, such as flashing via Odin.
Normally, when I had my previous Epic (SRF 1.0.1, EC05, Twilight Zone Kernal), before it was stolen, Wired Tether worked perfectly, especially with Linux (connect as "AutoUSB 0"), and I could mount my SD card.
Suggestions?

Go to control panel and have it update drivers from Windows Update. Takes a long time to get them all.

I get the feeling it's more than a simple driver issue. I have the same problems with Linux, and linux has native drivers. And Windows Update is useless. It can't even find drivers for my fingerprint reader. Nevertheless, I will try it next time I'm on my laptop. Windows on my desktop is fubar.

I had the same issue with my pc.. I ended up using an old vista lapptop and everything worked perfectly.. sometimes these pc's just straight out don't work with these drivers.. wish I could help you out more man

Maybe dialing ##8778# and selecting modem mode under the usb section will help automtically install drivers.. see if that works, it helped me out for the whole epic to boost mobile process

Epic 4g Not recognized on Windows 7 64 bit

I'm from the Evo 4G section of xda and just bought an Epic 4G from a friend to play around with. I've rooted and fully customized my Evo 4G and my uncle's Samsung Infuse. So I am not new to the rooting side of these phones. However, I just can't seem to get this to work no matter how hard I try.
Ok so I have done Google searches and sifted through the various "fixes" here on xda....I cannot, no matter what I do, get my epic 4g to be recognized on my Windows 7 64 bit.
I've downloaded and installed about 3 or 4 different USB driver files. I've gone through 2 different cables. I've uninstalled and even updated drivers via Windows. And I've installed and updated Kies. I bought the phone from a friend of mine who had done a full system restore before he gave it to me. So if there were any system issues they should be gone. When I plug in one of the cables the phone shows that the USB cable is connected and I have USB debugging on. But my computer shows "Uknown Device." Does anyone have any suggestions for me please?
I've included screenshots of what my computer shows me. Any help, or reference literature that I may have overlooked, that you guys can provide would be extremely helpful.

There's a few reasons this could be happening. You may want to try different USB ports on your computer or connecting through a USB hub. Also, make sure you're using the official Samsung drivers (you can search for them on XDA).
Otherwise, go to the dialer on the phone and punch in ##8778# and under USB make sure PDA is checked instead of modem. Hope that helps.

I too could never get win7x64 to work but had no problem on other pc running win7x86. I wasted hours trying. Uninstalled everything, removed all references in registry, used usbdevview, device manager, different usb ports, win update, and on and on and on. Gave up since I had other computer and it just worked 1st try. Please pm me if u find the solution. Would still like it to work on 64 bit. My thought is the 64 bit driver, but I hear others are working. :-O

Mine works fine on my 64bit Laptop. I had to update drivers once though since going to GB leak broke it. On my desktop it will only work if connected in the rear USB port.

I've used atleast 3 different computers with 64 bit windows 7, I never did anything special except for download the drivers from samsungs website...

I don't know what it is because I couldn't get the computer to recognize my phone on my uncle's laptop (which runs Vista 32). It kept giving me the same "Unknown Device" message when I went to look at the drivers.

Welcome to the Epic 4g xda section! It just so happens I was looking for Windows 7 64-bit drivers earlier today.
Here's where I found them: http://forum.xda-developers.com/showthread.php?t=798067
Then scroll down to the section "2.3 – ROOTING" and you'll find the listed drivers there.

Go here and get the drivers from Samsung:

AFAIK, that package should install the correct drivers for the OS.

I install 32 and 64 bit drivers for the i9000
Sent from my SPH-D700 using Tapatalk

I have literally the same problem, phone was reconized and connected fine when i was running xp 32 bit, installed windows 7 64 bit and nothing i do will work. Was your problem ever resolved?

All i can say is try extracting the drivers thru 7zip
then extract the files it gives you
then u should see like a folder and then copy and paste the
folder in the c: program files
and then go back to device manager and then actually manaually search for
drivers and that should work cuz it worked for me im using Windows 8

unfortunately that is one of the exact ways I tried to do it, thanks for the input tho. Just incase I over looked something searching for the driver manually, what sub category should my phone be under in device manager? thx

For those having trouble getting the drivers installed in Win7(x64/x86).
A workaround could be to use WUBI (Ubuntu's windows based installer that adds an option to boot to Ubuntu, while allowing it [Ubuntu] to be uninstalled from windows like a "normal" program).
Install WUBI, boot to Ubuntu, problem solved!
If the point of installing the drivers it to get Odin working...
The WUBI workaround would still work, you would just replace Odin with Heimdall (which is 100x better/more stable than Odin anyway).
I realise this is a lot to do for resolving a driver install problem, but... Heimdall pwns Odin anyway.

and if your in download mode when you hook your phone up
it will show up under modem it wil not show until you connect your phone

Ok I had to do the following inorder for it to work on my windows 7 x64 bit
I download the samsung epic 4g driver samsung_mobile_driver_v1.3.800.0.msi
I then used 7zip to extract the file
I then used the msi file and installed it
I then used 7 zip and extracted the samsung_mobile_driver_v1.3.800.0.msi file to a directory
I then DISABLE ALL INTERNET ACCESS ON THE LAPTOP BY TURNING OFF WIFI AND OR PULLING THE LAN CABLE OUT THE PC.
I then plug the phone into the pc usb slot
let the pc find the drivers
if it does not find them point to the extracted directory you did above and it will be good.
now do ##8778# and place the bottom into pda and if it cant find drivers point it to the extracted directory.
now turn phone off and go into download mode 1 key and power button and let windows find the drivers

Oh... my... god. I spent hours today trying to figure out how to get this phone I picked up to show me its sd card as a drive. Everyone on the internet seemed to be saying it was the lack of the right drivers, though they all disagreed on what the right drivers were. I tried so many different drivers, no luck.
That above, that I quoted: all it took. Why would it possibly be misconfigured out of the box in such a weird, impossible-to-locate way? Jeez.
(Anyway, I know I'm bumping a super old thread with this first post, but I felt compelled not just to thank this person for restoring my sanity, but also to bump up this thread's relevance for future googlers going as crazy as I was going.)

[SOLVED] Phone Not Recognized by Computer

Hello everyone. My E4GT is unable to connect my computer after I install the drivers. I tried reinstalling them, used different usb ports, and different cables to find out that it still wouldn't work. The weird think is when I connect my phone to another computer after installing the drivers, it works. I'm hoping that someone knows of a fix to this.
OS: Windows XP SP3 32-bit
Edit: I solved this problem. What the problem was that I was missing usb.inf in WINDOWS/INF . To get this file, I got it from the other computer. At the time of me doing this, my only goal was to fix my webcam because I was getting an error about a missing .inf file.

Looks like you tried different USB cables (hopefully NEW ones), and different ports too. Along with Kies.
Try going into device manager (check show hidden devices too!) and uninstall ANY Samsung drivers or software you have installed. And reboot.
Download and install the latest drivers for the Epic 4GT [ http://org.downloadcenter.samsung.c...342248/Sprint_d710_USB_Driver_v1_3_2360_0.exe ]
Reboot your system. Then try to connect again.
If you have some type of Antivirus/Antispyware application you may also want to try and temporarily disable it too. I've seen this happen before.

I'm pretty sure it is not my antivirus because the other computer has the exact same antivirus. Also, in Device Manager, I enabled hidden devices and I do not see any drivers that seem like they have to do with Samsung.

Cool, but did you uninstall, reboot and then reinstall? And did you also disable the AV just in case?

I rebooted my computer, installed the drivers, and it still did not work. It's like my computer does not know how to use the drivers for my phone.

Wow not sure what else to try. If you've tried removing all drivers and re-installing them, using brand new USB cable(s), using different USB ports and disabling AV software and if it does connect and show up on other PCs yet it still wont show on one PC, then something is amiss with that machine.
When you're connecting your device you do have it on too right? I'm sure you do but just checking.
Did you install any ROM on this device already? There are some international versions that if installed on this device disable the USB port.
And does it show up on other machines just not this one?
If it shows up on other machines than it there is something amok with that PC.
If it doesn't then..
One last thing you might want to attempt is to download sfhub's One-click FF18 http://forum.xda-developers.com/showthread.php?t=1721229 download the 'reset data' and extract the exe.
Make sure you phone is off and NOT attached to the PC.
Run the One-click application.
Simultaneously Press and Hold [Power] [VolDn] until confirmation screen appears
Press [VolUp] to enter Download mode
Then Attach your phone via USB to the PC and see if it shows up on a COM Port (anyone is OK).
IF it does you can then at least flash the stock rooted FF18 and get the device to probably work correctly next time you plug it in after of course the entire Odin/Update finishes and your phone restarts.
Just reaching here but hope that helps.

This shows up on other computers but not this one. I did install CM9 onto my phone, but when I was on stock, this problem was still happening. This is most likely something with this PC. Thanks for you help.

Well then that's it. PC is the issue it won't show. Something is pooped.
Good luck.

Just to be clear, when someone says, 'try different usb ports' make sure you only use the ports on the motherboard and not the ones on the front of the case or door.
It's the difference between powered and un powered.
That one the threw me for a loop on my win7 when I usually use my laptop with xp.

[Q] stupid question...how do I transfer files to/from my phone?!

hey guys.
just got a SGS3 for the wife and one for myself, coming from a long time with HTC Evos.
i'm having an embarassing situation...I don't see how to transfer files from or to the phone. I plug it in via usb, drivers installed automatically, computer told me the device was ready to be used...and nothing else. nothing popped up on the phone, nothing on my computer. the phones came with no software and Samsung's website does not list any drivers or software to download...
the phones are stock for now until I get a chance to root them this week or next weekend. in the meantime, what is the way a normal user is supposed to transfer files to/from this phone?!
I'm on Windows 7 on both the laptop and the PC, both have the same situation. with both phones...both fully stock but also updated with the latest software.
thanks for the help!

Weird...
it should pop up as a media device.
Plug it in and pull down the notification bar and touch where it says "touch for other USB options"
and make sure Media Device (MTP) is checked.
if it doesn pop up then either the drivers arent installed, or their not installed correctly.
or the cable is bad, or the USB port is bad.
or the devil is messing with you

make sure you have automatic updating on in windows, at least for the drivers. this is why i hate MTP, its such a pain in the ass. i sure hope someone gets mass storage mode goin in these soon. Make sure theres no unknown devices listed in the devices manager. then grab and install the drivers from here(although you shouldnt need them for mtp to work) http://www.samsung.com/us/support/owners/product/SPH-L710MBBSPR#

downloading now...when I plug it in, the cell phone makes a little noise. but no prompts come up under my notifications.
on the PC I found it the phone shows up under Devices & Printers, but there is no way to interact with it other than to see it's drivers and that they all apparently are up to date and functioning correctly...
ahhhhhh

Does it show as a plain looking generic box or does it look like an MP3 player in devices and printers?

Generic box under an "Unspecified" category. Even after reinstalling the drivers...same situation. I can't double click to open the phone and there is no prompt on my phone.

the phone is seeing as a modem by the PC...i'm guessing because of the drivers. can one of you tell me which drivers your phone is using (under Device Manager) so I can manually select those? I have many installed Samsung drivers, just need to know which one to pick I guess.

This is crazy. I curse Samsung for this mtp ****t I swear. Under portable devices. Device name should be SPH-L710--thats what ur looking for. Will probly also be listed under modems as Samsung mobile usb modem. And in the usb devices as Samsung mobile usb composite device.another thought If you didn't already, turn on usb debugging and let it install those drivers as well. Has helped me in the past. Maybe even switchin it to download mode just so windows can see it in all modes and maybe wake the hell up.

i had usb debugging on originally, turned it off. no difference.
I went and bought a new memory card reader that supports SDXC cards, so now I can at least remove my memory card and transfer files...but still doesn't help me. I want to use that extra internal space I didn't have on my Evo 3D to add more music still to my phone...so I need to connect it to the PC somehow!

it blows my mind that its not working. what version of win 7 do you have? x86 or x64?

we have a laptop and a desktop, both running Windows 7 x64. we also have two of those Galaxy S3 phones. I'm running Go Launcher, my wife using the stock Wiz launcher. I have tried in different USB ports in both laptop and desktop, using different usb cables, and with both phones. with and without adb debugging enabled. same situation.
the phone shows up as a modem under device manager. under SAMSUNG Android Phone there is only SAMSUNG Android ADB Interface listed, nothing specific to this phone. I have tried changing the drivers around to different built-in samsung drivers and drivers from when I had the Galaxy Tab, nothing. I downloaded the latest drivers as they were linked above, nothing.
there are no pop-ups on either phone and nothing on the computer beyond the noise of something being plugged in...
w.t.f.

OK. Don't think its the issue but have run into this before with a Samsung phone or two. Reboot the computer and hold down f8 as its booting. When the advance menu comes up, hit *disable driver signature enforcement*. Like I said I don't think that's it but that has caused problems for me before (thanks microsoft) on x64 bit windows and a Samsung android phone so might as well rule it out.
O yeah, and just to make sure, you dont have kies installed right?

I do have Kies installed. someone now suggested I try using it to connect my phone. I open Kies, connect my phone, it says Connecting...and never goes anywhere. I did the connection troubleshooting thing, it took a while, said it was complete, plugged the phone back in, same situation.
jeez this is really stupid.

i disabled the driver enforcement option. nothing.
I rooted the phone now. installed that easy UMS apk and set the phone to MTP mode. now I have a Samsung MTP device on my device manager but none of the drivers work with it. windows couldn't find a driver, and i've tried 6 drivers manually and they all say they can't start the device.
anything else I can do now that i'm rooted?

I do have Kies installed. someone now suggested I try using it to connect my phone. I open Kies, connect my phone, it says Connecting...and never goes anywhere. I did the connection troubleshooting thing, it took a while, said it was complete, plugged the phone back in, same situation.
jeez this is really stupid.

kies is the devil
its actually the opposite. You DO NOT want it installed. Uninstall kies completely. Idk how I forgot about mentioning kies.nothing but problems. Nix it and I bet this headache ends. And if u take that advice, have the phone unpluged during then removal . I would also recommend reinstalling the Samsung drivers I linked to yesterday. Then plug the phone in and I would bet smooth sail in from there

will try. now the phone shows up the "connected as media device" notice when I plug it in, and the PC sees it as an MTP device...but still not letting me use it. lets hope uninstalling KIES helps.

Sounds like progress. I think uninstling kies will do the trick

well I uninstalled Kies, told it to uninstall any and all drivers for mobile phones. cleaned my registry. restarted my computer, installed the drivers fresh, plugged in the phone and it seems to work. for the first time it shows as a mtp device!
thanks a million. let's hope it works to transfer files.

[Q] Phone no longer gets recognized as USB storage on PC

I've tried this on both my work PC and my home PC. When I plug the phone in, it makes the familiar connection sound and will start to charge but the computer doesn't ask me if I want to open it up for USB browsing. This is recent and there have been no firmware changes. I've rebooted the computers and the phone but nothing seems to matter. Has anyone else encountered this issue?

do you have developer options (in settings) on or off? Has the usb cable been roughly removed from the phone lately. it may be damaged?

developer options are off, I've also tried several cables

Are you rooted and on a custom Rom?

It doesn't mount as a USB drive, it mounts as a media device because it uses MTP. That's not an issue with the phone, it has to do with how Samsung set it up.

Do what the poster above me said, then make sure to unlock your phone after plugging it in or else your files won't show up

Its the same thing i can't transfer files to the phone or the external card.I don't get it i never had a problem with my galaxy 2.I've uninstalled the drives installed them again and used different cables.

i have the same problem too. my phone nolonger shows up as a storage device on my pc. i have developer options on and usb debugging checked. ive tried different cables , different computer , tried rebooting phone, tried reinstalling the drivers too .. nothing seems to fix this issue... earlier today it was working fine .. when i plug it in it pops up samsung modem and thats it.. please help

This is very strange, as a work around you can use Wireless Transfer. I've used this as my main method since my OG Epic.

same issue trying the fixes mentioned. after reinstalling the driver i get about 3 files transferred then it pops up with that error....WTH is goin on i have several gigs of books and music how am i supposed to get them off?

THis is complete crap! why is this goin on?! I can get my pc to recognize the device i can browse directories but it suddenly tries to decide when to quit when i try to transfer files. I can only get about 5 folders moved before it thinks thats all and just stops it no longer comes up with the device not functioning error message anymore.......please somebody help. I dont have a large enough sd card to just transfer. Ive searched on google and there are not actually explanation only that you cant mount the internal storage as mass storage.....samsung is going the way of HTC for me. Stupid oversights renders the device a complete waste to me. !!!!!!!!!!!!!!!!

Ok last one. I was considering getting the note 8.0, is this something that all of their devices are gonna suffer from?

I'm not going to pretend to know what's wrong with your device, as I have 2 Galaxy S3 and a Gnex and 2 Epics which all connect just fine and I can transfer any and all files from the desktop or laptop no issues.
But I will suggest maybe you set up a drop box and you can share all those files from your phone to computer or visa versa.

well after a couple deep breaths i went ahead and did that after posting those. I still cant locate a reason why it would come up with that error. There are a couple posts in another forum talking about it being win7 related and not the device it self. Ive tested other cables, rebooted pc/device, checked/reinstalled drivers, and nothing come up out of the ordinary. I hope someone locates the issues, just for having an answer to this headache. thx

An answer-
For those who are having issues insure that your device is on a Stock TouchWiz ROM.
MAKE SURE DEVICE IS UNPLUGGED THIS ENTIRE PROCESS.
1.
= Go to the Dialpad.
= Enter this code ##3424#
= Menu will pop up click Qualcomm USB Settings.
= Click the 2nd Option MTP+ADB
= Press Save
Done
2.
= On your computer go to Control Panel Click Category for the viewing style.
= You will see Uninstall A Program. Click that and go to S- Uninstall Everything Samsung.
= Plug your device back in and let default drivers install takes average 45-60 seconds.
= Device detected as MTP. You may now transfer files.
Done
Let me know if this worked for you.

As you said, the CDC serial (Unknown Device) popped up. Unplug your device and install drivers.
http://www.samsung.com/us/support/owners/product/SPH-D710
Click "Download" tab at the bottom and press the "EXE" button to download.
-Plug your phone back in afterwards and keep "Device Manager" open you will see the CDC Device disappear.
-When its installing I recommend keeping the "Installing Drivers" window open to see when everything is finished.
-After that's done switch phone to PTP via the notification menu. Let it load drivers and it will install as a camera.
-Switch back and MTP should be working.
Let me know how it goes.
