[Q] Cannot install Windows 7 64 bit Drivers

I've tried everything I can possibly think of. I have an Asus Laptop with Windows 7 64 bit and absolutely cannot get my Epic to be recognized. I've uninstalled and re-installed the driver more times than I care to mention. I've tried mounting the device to no avail either. I've tried plugging in the phone into each of the USB ports on the laptop to no avail. I need to get the computer to recognize the device so I can get odin to recognize the phone so I can flash back to stock. Right now it doesn't do so. Does anyone have any ideas of what I can do to get this up an running?

Try installing the 32-bit drivers even if you're on a 64-bit computer....

The same issue comes up. It says that the drivers are not successfully installed (even though the installer goes through) and it says "Unknown Device" over and over.

Are you removing previous drivers?
then rebooting before installing new drivers...
also are you using stock cable?
if so buy a new cable you can get cheap ones online for like a dollar just search micro usb cables

Yes, yes, yes. Does the cable really make that much of a difference? I saw that people have had issues but I mean it charges properly all the time so I figured it was ok to use.

Absolutely!!!!!!!!!!!!!!!!!!!!!!!!!!!1
That cable is worthless get a Blackberry cable they are very durable and dependable.
i was having problems also..... all because of the cable.

I'll probably go buy a cable from Walmart, order a cheaper one online from Monoprice and return the other just so I can odin my phone...I really hope that's the issue though.

does it keep looping "unknown device" in the corner, almost like you unplugging and plugging back in repeatedly?
ifso try cleaning the contacts of the usb port on phone and on the small end of the cable.
if not then try totally uninstalling the drivers you installed and if possible when its saying "unknown device" open the device manager, r-click then unistall in there.
USBDview has always been able to dig me out of the home when ive had usb related driver issues... just run it and delete/uninstall anything samsung/android/adb etc related, reboot pc and phone then try again...maybe even redownload the drivers

update (you replied as i was typing): one bandaid for the cable you could try for now is to take a needlenose pliers or something and slightly squish the micro end to try getting a tighter fit.... i had to do that to the cable i keep at work.

You can always just download kies. That's what I did. When I was trying the standalone drivers I had trouble. Installed kies on both of my laptops and coding works beautifully everytime. And I seriously think you guys are ill. Its a cable... its digital. It either works or.it doesn't. I use my samsung wire exclusively. Its thin and I like contour on the plug. Both cables have worked flawlessly on both of my epics.

You are wrong.
Cables can have breaks in them which give them intermittent connectivity. Also, since this cable has several (5 I think?) single strands of wire in them, a single wire could be screwed up causing this (or the pin for a single wire on either end) That would still allow it to charge, and partially be recognized by Windows, but not allow it to fully communicate causing this problem.
I have a cable that I only use for charging because it has this EXACT problem. Another cable works perfect, but this particular cable gives me the unknown device.

Right.. so it either works or it doesn't lol if both cables are in perfect working condition then there would be no issue. Its all preference. I personally use a blackberry micro usb cable. It locks in to the usb port on the phone better. Just so im not paranoid about the wire coming off while flashing... cuz thats bad lol

I didn't articulate myself clearly, but that is my fault.
If a single wire inside the cable is broken (for the sake of simplicity let's just say it is the RECEIVE cable - from the device to the PC). The PC can recognize that there is a device there, but because the device can't talk to the PC, Windows can tell there is something there, but has no idea what it is since the device can't talk back to the PC. Also, in this scenario the cable would charge just fine since those individual lines are intact.

To quote u "Yes yes yes" it does make ALL THE DIFFERENCE... I had the same problem and made serveral posts about it when the phone 1st came out, I tried everything... Uninstalled/Reinstalled/Rebooted many times, Manually deleted the folders where the drivers are held then Re-installed, Installed Kies (which is a P.O.S. and was a BIG WASTE OF TIME imo.) I tried everything and just about gave up until 1 day i looked @ my roomate and asked him 2 let me borrow his cable to his cheap cricket phone 2 see if it would make a difference.
Well it worked... Get a new cable, if you've done what ive done and it still doesnt work, its the cable and not the drivers

I've done just about all I freaking can on this as well.
I've installed, un-installed, and re-installed the drivers. I'm running Windows 7 64 bit on Bootcamp.
I've used USBDView, I've uninstalled all of the connected drivers. They get re-installed, but the phone keeps keeps coming up as an Unknown Device. I try and locate the Samsung USB drivers directory, but it keeps coming up as Unknown.
Does anyone know specifically what directory I should use choose when trying to manually link the driver in Device Manager? I'm having a ***** of a time here.

Anybody have any ideas for me? Thanks.

I had the same problem. Buy a new cable from monoprice. The second I bought a new cable for my 64 bit Asus laptop it worked.
Trust me, buy a new cable.

I had the same problem. I didn't follow directions to solve my problem in Odin. I had to start Odin and plug my phone in and quickly put the phone into download mode. I did that a few times and finally got it to recognize. With Syndicate, it now recognizes every time. I say that now. LOL

This is how I fixed this problem. After doing all I could think of, uninstall, install, system restore, nandroid restor to when phone was being recognized... all these didn't work for me. I still got the same unknown device in device manager.
The fix: with samsung epic drivers already installed. Turn the phone on, plug into your computer. Let device manager find unknown device. Power off the phone. Boot into recovery. Pc will recognize your phone as samsung android device. Reboot your phone and you should be good to go. Hope this works for the rest of you. Good luck.

Isn't the original issue that the driver install fails? not that the device isnt being readed?

[Q] Windows 7 Doesn't Recognize my Continuum...

So I'm attempting to root the Continuum, but for some reason the phone won't effectively connect to Windows 7. For example, when I hook the phone up to my Samsung i7 laptop, all the phone does is charge. It doesn't even ask me if I would like to use usb storage or anything. The computer also doesn't recognize the device. Any ideas? Thanks!

A couple questions first:
- Did you install the Continuum drivers?
- Does your phone bring up the USB connection in the status bar?
- Does it bring up the Verizon VCast website on connection?

1. I likely did not install the Continuum drivers, and I have no clue where to get them. I'm assuming Samsung's website, but it's a bit hard to figure out and navigate...
2. My phone does not bring up the USB connection in the status bar.
3. When I go to the browser, it brings up the Verizon website with news, etc.
It should probably be stated as well that this phone is not activated. I am using it on wifi only for the time being because I traded it with a friend for another phone.

Alright, so I've figured it out. Strangely enough, I was just using a generic USB to microUSB cable, and I actually needed to use a Samsung cable. Weird, right?

So...now that I'm rooted, how in the world do I install a custom rom? I saw that there's a ClockworkMod Recovery out, but what does "Odin" mean? I'm coming from an LG Optimus V and have extensive experience rooting and installing custom roms and recoveries, but I've never heard of that before. Thanks again!

First, we dont have much for custom roms on this phone. The couple we do have contain fairly well written "how-to's" for them.
Second, if you are not sure, do some research and find out as many answers with the vast pool of knowlendge at your fingertips (the interwebs) as you can. There has already been a swarm of questions asked, and I am sure the answers may already be there for you.
I am waiting for the update and Froyo roms to come out before I bother with custom roms, but I am not holding my breath for that. I will probably be on my next Android phone before I will bother. Modding it up with Widgetlocker, ADW Launcher, and some other goodies at the moment to tide me over.

I had this same problem today. USB mass storage wasn't working, adb wasn't working. I wasn't using the samsung cable, but I can't see how that would make a difference, as the cable I was using has worked for literally a couple dozen different phones from different manufacturers - including other samsungs. I had the samsung drivers installed.
The owner claims that only media sync works on his computer as well, and that usb mass storage has never worked. Anyone have any ideas on how to fix this?

i am also getting this problem. as far as i know i am still using the samsung cable, as normal micro-usb cables dont fit in the continuums port. ill look for another one, but this is quite odd. what i have done (all windows 7 64 bit):
drivers uninstalled
drivers installed
lagfix on
lag fix off
factory reset (within adrenalyne's rom)
i am going to try to transfer the stock rom via bluetooth and see if that works
edit: turns out that isnt possible without odi recognizing the device, which it doesnt (not even in download mode). this is very peculiar
some more information: nothing even shows up in device manager. no unknown devices, nothing. the phone charges, but thats it. i might go to the verizon store and see if i can get another cable

My guess is because you are using a 64 bit version of windows..

Why would that matter at all?

The 64bit version of Windows 7 is notorious for not being compatible with a lot of devices. There just arent any 64bit drivers. If you dont understand how to run your software in the proper compatibility mode you will run into problems. I used the x64 version of Win7 for about 12 seconds after I realized my ancient usb optical mouse didnt work lol.
My advice, try running the Samsung driver installer in compatibility mode and see if that doesnt help.

Compatibility mode won't do anything in the case of drivers. I'm not sure what your issue is though as all of my Samsung phones have been picked up fine from within Windows 7 x64. Is the phone picked up on any non-Windows 7 computer? Have you checked in Device Manager to see if it just needs installed?

its the cable. i took mine to the verizon store, they tested it, and gave me a new one for free. works perfectly now

Excellent, problem solved!

So it turns out a factory reset fixed it. Using a moto cable. So that's definitely not the issue. Flashing froyo now. Thanks!

I have encountered that a few times also. Its weird cuz when I plugged the usb into ac charger it almost immediately asks if I want to mount sd for data transfer. 20 mins later I unplug usb from unit and plugit into my win7 pc and nothin? So plugged back into ac unit and it recognize....so I mounted and it didn't know what to do lol. I then plugged back intopc...waited...changed orientation and 'Boom' pc sees it...in fact I change orientation whenever it seems to hang and seems to work....
sent from my XDA phone - its more than a continuum

I should also note that I have never used a samsung cable and every usb micro I've used (moto,kodak,BB,Lg) has fit and worked. But I have noticed some usb related quirks since froyo update like no lock screen after charging till I push home button, inaccurate batt icon (goes from 3/4 to 1/4 in like 10 mins but overall batt life is same as before)...
On an unrelated note I also can't get v6supercharger to work...?

GNex not recognized in Windows 7

I need help getting my Windows 7 x64 to recognize my GNex.
Whenever I plug it in I dont hear the default USB plug-in sound (Windows), but my phone is charging.
I cannot mount my storage either in recovery or inside Android.
My device manager is not showing errors and my GNex at all.
Tried installing the Google USB Driver from SDK, no luck
Tried PDANet which did not install because of missing drivers.

Use a program called usbdeview and uninstall the drivers you have installed for the Gnex. Then use the galaxy nexus toolkit to install the correct ones.

You dont by chance have the "fast charge" mod enabled through your kerenel do you? Because if so you will need to disable the feature first before plugging up to you Windows machine.

This is starting to become an "epidemic".. :O

I can almost guarantee that it's usb fast charge, devs should really put a warning on that

I too have a Win7 x64 laptop and had a similar issue, but the Device Manager did report an error with the Android 1.0 and/or Samsung driver. I had to manually update driver for it to work thru Device Manager.

Woops. Well there are some ways to check what is disturbing the connection. Let's start at the beginning:
Check if your phone is configured to interact with your computer. After conneting your phone you should get a selection list in your phones notification bar. Make sure to select usb storrage from that list.
On your windows computer go to [start] and type "device manager". After the application (that shows all hardware devices connected to the system) loaded connect your phone and check if something changes. If everything works all right you should get your nexus. If a question mark apears double click it to check the problem.
Try yo connect your device to another computer or with another cable. If the problem is not solved by above steps contact your seller.
If this is not possible install Airdroid and connect your phone to your computers browser or ES file Explorer to browse your pc over the network

Ok, I'm having this issue, but Windows doesn't even recognize anything is plugged in! I tried it on a TON of computers at work with several different USB cables. Nothing! All I get is charging, but no options in the top menu or anything. Is this a toasted Nexus? I just got it, now I can't even transfer files to its storage. I've been transferring files through dropbox...which is annoying...if it is USB Fastcharge, how do I disable it?

Their IS a fix for this, but we need the code to get into the PhoneUtil menu and turn USB back on.
It's an issue with Samsung phones apparently, and here's a fix someone found a while ago.

What annoys me is that when I got the phone it was already rooted and I didn't have a chance to try it stock or back up the original. It was rooted with an older version, so I flashed 4.0.4 on it. Check out the reviews on newegg I'm not alone in reporting a messed with Galaxy Nexus.

My issue is definitely hardware. I sent my GNex back and they sent me back a new one which I received yesterday. I checked and this one wasn't previously rooted or Unlocked. It worked for a day (worked as in windows saw it and I could xfer music/books/comics to it) after I get home from work Windows stopped recognizing it. I did NOTHING to the phone, it just stopped being seen by windows. I only used the cable that came with it and charged it the night before using the supplied adapter, but the USB still stopped working. Last resort I did a system restore to the phone and the USB still doesn't show up in anything ,Tried 5 of my Windows PC's A bunch of PC's at work, my friends Mac, my Ubuntu powered Netbook, my Xbox360 and PS3, even the Transformer Prime using the keyboard dock. This is telling me it's a hardware issue with the Device. Might be somthing wrong with the latest batch of GNex's but the USB seems to give out. Even if I put the phone in ODIN mode NOTHING recognizes it. So, before you all waste your time finding a fix, this is 100% absolutly a hardware issue with these phones, I don't know why, but I had Two bad ones in a row, and am Hoping my 3rd isn't borked too.
I have a bad history with Android phones....My first Nexus One wouldn't stay on, so I got a replacement from HTC. My first two G2x's would constantly reboot, It wasn't until the 3rd one that I got a working one. Now I'm hoping I don't have to go through 4 bad Galaxy Nexus' before getting one that actually works!
I have the opposite luck with tablets....the Novo7, Iconia A100 and Transformer Prime have been perfect outa box. This ordeal with android phones makes me seriously consider exchanging the GNex for an iPhone4s....but the iPhone4s screen is SOOOOO tiny!!!

Galaxy Nexus USB Not Working

Try ever so carefully bending the usb port up towards the screen. Maybe with a tooth pich so you do not scratch anything. My SGS2 did this and after tweaking I had ZERO issues.

I just tried that it sometimes works now (rarely though ). I also noticed that the phone charges its just the MTP that isnt working

Same issue...
Went to root my Gsm gnex... Couldn't connect to the pc...
And now whenever I go into gallery it force closes... Could it be an issue with the internal storage?

Is there any chance that you've got fast-charge enabled (say if you're running a kernel that allows it and some script starts it upon boot?)? If so, then USB Storage or MTP isn't going to work and isn't supposed to until you do this:
1) take it out of fast-charge mode (like with .. trickster mod or an "#echo 0 > /sys/.. {wherever it goes, have to google it},
2) unplug USB
3) plug it back in
4) hopefully it'll work if that was the problem.
Just a thought and it's happened to me. I use a script I wrote on boot to enable fast USB charge and another from userspace to disable fast charge so I can see the drive.
Good luck.

I use Trinity Kernel and I made sure fast charge is disabled. I even flashed from Rasbean to CM10 to make sure it isnt related to the Rom or kernel. I'm guessing it might have something to do with the usb port in the phone as sometimes it connects but disconnects after a while
Thanks anyways

Ah well, too bad. I guess if you need to get to your PC and don't mind reduced speeds, you could always use a cifs (common internet file system) aware kernel, (faux or air I think, maybe more), then use cifsmanager to mount whatever PC share you like and transfer over the air for now.

checked driver installation on both PC's ????

hardware issue?
I did some research and came to conclusion that it is most likely a hardware issue. I had tried bending the pin inside the USB port but that didn't do the trick for me and seems to be a rather unreliable solution. I found a guide to replace the port yourself on ifixit. Since I don't own the tools and am not very good in repairing those things myself I had mobiletechvideos do it for me (i'm not allowed to post a link but you'll find it by googling for it).
It's a fair price for not having to do it myself and risking serious damage to the device. I got my phone back after 9 days and since then it has been working like a charm.
Anyway, it sucks that the micro usb port is that fragile and got damaged so easily in the first place.

I had connect problem and everyone kept saying i needed to install drivers and sending me to toolkits. I KNEW drivers installed. Turned out to be the usb inf file in sdk only had nexus one, ns4g, and the 7 wrote in. I copied the gnex info to the file and rebooted computer. Worked perfectly. Didn't even get the new hardware popup.
*Shaolin Shadowboxing*

I've been using trinity and noticed that sometimes it doesn't recognize the USB when plunged in after it's been up for awhile... Something happens when it's been on for awhile I don't know if it is fast charge related or not..
My solution... reboot the phone with the USB plugged in.. works EVERYTIME...

Phone Charges but wont connect via USB

About 2 weeks ago my phone started having issues with the microSD card. I was plugging it into my computer off and on trying to get the card to read. Then one time the computer just stopped recognizing the phone. Since then I haven't been able to get any computer to recognize my phone. I plug it in and no MTP / PTP options show up, nothing in the system tray to indicate I have attached a new USB device. It just charges the phone.
Phone info:
Samsung SGH-i747m
Android version 4.2.2
Baseband version I747MUMLL1
Kernel Version 3.4.37-cyanogenmod-g7b457dc
What I've tried:
Uninstalled and reinstalled drivers
Every USB port on the box
Factory data reset--both from the setup menu, and the diagnostic bootup menu
USB debugging mode, both on and off.
Changing the UART and USB settings in the *#7284# PhoneUtil. After my last factory reset, it's set to PDA/MTP+ADB.
3 different computers, one Win 7 64 bit, one, one Win 7 32 bit, one Win XP SP3
about 5 different USB cords
I tried a touchwhiz rom CSROM
Cleaning the USB connector with a pin / air can
Changed the Kernal
Anything else I should try? Is there a way to determine if the USB plug on the phone is bad?

Every USB port on the box
Factory data reset--both from the setup menu, and the diagnostic bootup menu
USB debugging mode, both on and off.
Changing the UART and USB settings in the *#7284# PhoneUtil. After my last factory reset, it's set to PDA/MTP+ADB.
3 different computers, one Win 7 64 bit, one, one Win 7 32 bit, one Win XP SP3
about 5 different USB cords
I tried a touchwhiz rom CSROM
Cleaning the USB connector with a pin / air can
Changed the Kernal
Anything else I should try? Is there a way to determine if the USB plug on the phone is bad?

What ROM are you using? Not stock obviously running 4.2.2
Make sure fast charge isn't selected. You can't use USB with fast charge enabled. There is either quick tile setting for it (aokp) or under performance settings or in ktweaker.

Is your USB port open? Example: at my office desk, USB only charges but does not allow devices to connect.

Thanks for the reply. I've tried about 5 different roms, some touchwiz some not. Haven't gone back to stock yet though.
However I went back to a AOKP rom, Tasks650. Haven't been able to find the usb charge toggle button yet but I may have a kernal not compatible with it. However when I plug the phone into my computer and look at the Battery is says I'm on AC charge so that is likely a good place to start looking for a solution.
Thanks again.

yeah, I've used the port before these issues started and it still works with my Galaxy Nexus.

If plugged into USB it says ac charge than fast charge is enabled. That's what it does. Goto setting and find the sub menu for the quick setting tiles. There will be one for fast charge. You select it, drag down your quick tiles and you can select and deselect it.

Faulty cord. Go on amazon or order another one. I use a heavy duty one from mediabridge for $5 and it does data and charging. Many times over the years I get an OEM micro usb cord that charges all 3 different galaxy S models I have then after use it will work on 2 and then only one. Sometimes it will just charge and not work with data transfer.
I highly doubt it's your phone.
I saw you tried different cords but were they new ? A picky microUSB or one that's more worn out might only work with a certain cord.
You can replace the microUSB port and it's cheap and I assume there a video on youtube for it but off course it's up to you.

Downloaded a new version of Task650 and enabled fast charge, reset the phone and then disabled it and reset the phone again. Same issue. PC does not recognize the phone but it charges. Check battery and says its on 'AC' charge. I wonder if somehow the two middle pins on the phone got shorted out so it permanently thinks its on AC charge?

Yeah, I just got 10 new microUSB cords to the house. They are cheap ones. However I tried a few other ones I have around the house. I don't know if any of them are the original Samsung cords but I certainly have original HTC microUSB cords. I've probably tried about 14 different ones in total now. I don't think its the cord.

I am in the same boat , my phone works perfect on Win 7 but not on Win XP.
I use airdroid or mmc adapter only if needed.
I did try a web link to fix the mtp issue ( before my xp pc was refomated ) and have had the phone recognized as a USB drive , can't find the link anymore. It has something to do with windows media player .
If I find something , I will report back.

Warranty exchange ? If it is the port.... It won't get better. I'd exchange or try a swap

On your windows XP device, download the newest version of Windows Media player. That always got it working for me.

I have this same issue now. Is WMP update really the issue here?

About 2 weeks ago my phone started having issues with the microSD card. I was plugging it into my computer off and on trying to get the card to read. Then one time the computer just stopped recognizing the phone. Since then I haven't been able to get any computer to recognize my phone. I plug it in and no MTP / PTP options show up, nothing in the system tray to indicate I have attached a new USB device. It just charges the phone.

I've been having the exact same problem with my Note II - couldn't get my PC to recognise the SD card but it would charge.
However, then it stopped charging my phone, too. I naturally assumed it was the USB port or the lead, but having tried four different leads - all tested on my wife's SII and all working fine - I realised it was something else.
So I swapped in the spare battery I have and that did charge; swapped back to the old battery and that charged, too.
Weird...but OK, phone is working again.
Next day, no charging again.
Swapped batteries - no change.
Swapped batteries back - no change.
Reflashed ParanoidAndroid ROM - no change.
Flashed Samsung base ROM - no change.
Flashed ParanoidAndroid again - batteries start to charge on USB and on wall charger.
WTF????
Two days later (yesterday) - batteries no longer charge. I'm having to use an external battery charger that plugs into the walls (take the battery out of the phone, plug into the charger, leave to charge).
I've tried different kernels (Devil, NEAK), leads, batteries - nothing.
It's just goddamn weird - and a real pain. :crying:

Sounds like I would start with warranty for the batteries. Stranger things have happened because of batteries. On the inspire, when a battery would start going bad the phone would reboot when trying to take a photo with the flash on.

I Managed to fix the "Usb not detecting with PC when you connect it but only charges the phone. With me it was a software problem because it happened after i installed the new firmware. what i did was root my phone using Framaroot 1.4. its a apk application, then i installed Titanium Backup. went into titanium backup then to the MTP application and backed it up. then i restored it +all date,. plugged my phone in with the pc and it worked.

Mine turned out to be a software problem, too. I moved to the Beanstalk ROM and that fixed it, weirdly.
I've changed ROMs since (PACMan and SlimBean) and everything's still fine...

Try This

By default my phone was already set to the right settings for USB file transfers so I’ll assume most of these ship with the same configuration, Somehow it changed. I found this on a forum - it seems a few other folks declared it a success.
1.Launch the phone key pad on your note and press *#7284# (don’t forget to start with that * symbol!)
2.When you press the last pound sign (#) this will bring up an option that will allow you to change your USB connection settings (modem or PDA) – change it to PDA.
3.At the bottom there is a button that says Qualcomm USB. Click on it.
4.In that menu click on MTP + ADB option.
5.Save and reset.
6.Wait for your phone to restart.
7.Plug the micro USB cable to the Note 2 and the the other end to your PC or Mac
8.Let your computer down load and install drivers.
9.Once installing is done, unplug then replug phone.
10.There should be a USB symbol on your phone in the status bar - click on it. It should ask if you wsnd to use mtp or ptp. Click MTP
11.At this point your PC should open the phone’s folders in explorer.
12.You may have to repeat this process a few times....it worked for me after 4 tries.
Remember, you do not need to use Kies or root your phone for this to work and you should not have to fiddle with manually installing and downloading drivers in Windows 8, it should work no problem as is.
Good luck!
