[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...?

What I really really hate about this phone? No native USB support

The usb storage. MTS or whatever you call it . Very slow, terrible for navigating/editing multiple directories/windows at once. Frustrating. Can only find size of files by going in the directory and selecting all files. Anyone know of a good quick solution to this? I've played with the common game editor but don't really see it as encompassing the solution to all the problems of not having the classical USB mount

You think thats bad? Try having Mac. I can't even get it to recognize me phone lol. I'm forced to used my windows machine.
And I believe its a JB thing, not necessarily Samsung.

I had this problem too with my macbook pro then I found a solution tonight. Try this:
1. Install Kies if you haven't already, if you have make sure it's updated.
2. Connect your phone.
3. In Kies, click Tools, then Install Drivers (this will reinstall drivers
4. Download Android File Transfer.
Should work after this. Also make sure you have USB Debugging on and use PTP not MTP.

I will be sure to give this a shot tomorrow and send along an update. I rarely use Kies, updated it yesterday but never tried the drivers thing. Android file transfer never used to work but maybe the "install drivers" step is all that's needed.
And thats why I love it here on XDA. Thanks for the help brother!

I agree... coming from a s2 skyrocket, I really miss UMS. Why bother having expandable storage when it takes hours to transfer to a class 10 32gb sd card? That is if I can get it to transfer at all.
I'm now resorting to unmounting sd card and putting it in the computer to transfer files...big PITA
SGS3 Easy UMS doesnt work either.
Edit: Actually, I'm using kies now... still miss drag and drop

Agreed. Always had driver problems with this phone. Sometimes it wouldn't connect because drivers failed to install or "bad hardware ID" pops up in the corner. Only way to get it to work was to restart comp. And it would only work until I disconnected it, then gotta restart again. -.-
I'm gonna switch back to linux once I get some free time. I recommend you do the same.

It was a problem in ICS as well. I think the reason for that they went with MTP is that users would create a "messy" file structure when they randomly dragged and dropped files anywhere on both the internal and external card. Samsung can keep things organized when they encourage you to use Samsung Kies to add files to the device.
The mandate for MTP is also to reduce piracy of protected media files by ensuring the DRM is properly done. In the past, I could connect my phone directly to my Samsung SMART TV and play 720/1080p movies via UMS. This is now blocked with MTP.

Thanks I also noticed the slow data transfer speed when I upgraded my SII to S3. Thought it was something I was doing wrong. I've changed the default transfer to PTP and will check it out tonight.

Don't bother with PTP. PTP is just a camera. It's not like UMS so you might as well leave it on MTP

I was annoyed by this as well. Now when I want to add something to my sd card I just take it out of the phone and put the sd card in my Mac and add files that way. It's a little annoying but its not that big of a deal.

I think the closest you'll get to a true UMS experience is using Samba Filesharing Server (https://play.google.com/store/apps/details?id=com.funkyfresh.samba). You can then treat it like a network shared drive.
Of course you'll be limited by your WiFi speed. I think a possibility would be a USB host adapter and a USB ethernet adapter. I'm not sure if Android has support for a USB ethernet adapter but if that works then you should be able to connect to a gigabit switch/adapter and just be limited by USB2 speed.

It's not just this phone in general. They're all going that way as of ICS (Honeycomb as well) and up. If you use Windows it's not terrible but it is still slower. And yeah trying to use it with my Mac or even my Linux box is just frustrating. The primary reasoning was to merge the data and application volumes to give more space for applications. This is a better explanation of it. I do miss USB storage mode though.

Yep, totally frustrating for me also.
I remove my microSD card when I need to do lots of file management. But it's a clumsy workaround.

[Q] My Nexus doesn't connect to the PC? Help?

Just came back from holiday so I've got some pictures to store on my computer, but I can't get my phone to connect to it. It charges fine when connected which is also bemusing, since it can't do anything else. It's definitely not my computer's problem as I've tried other computers to no avail. I've been looking around the internet but none of the solutions worked for me.
My Nexus is rooted with stock ROM on 4.2.1 Jelly Bean and hasn't had many other problems in it's lifetime, although sometimes when I go into the Gallery app it will tell me "No external storage available" and I cannot use it until I restart the phone, where the problem diminishes and reappears after a few days. I was wondering if these problems were linked in any way perhaps?
Thanks for any input guys, would really appreciate it

Is USB fast charge enabled?

I had the same problem - turns out it wouldn't connect on my PC's front USB ports, but does work on the rear ones.

first be sure that fast charging is disabled, second try other usb port if not try other usb cable if not try another computer, if not...i dont know!

That cannot be the issue. I did not have USB debugging enabled but I was still able to transfer the files. But, you can try re-installing the Google USB Driver or Samsung Driver for I9250 or was it I515?
Cheers

Check on computer that device is showing in devices and has correct drivers installed. If not samsung official manuals and downloads website (google it) has a driver pack (approx 30mb) which when installed should have every samsung driver you could need, download and run then reboot computer and plug in phone, all drivers needed should now install correctly.
Also check in usb options when first connected that mtp is checked so storage is visible to computer. Best of luck and if all else fails pc out of window sounds like fun
P.S. try flashing latest gapps to fix gallery issue, after dalvik and cache wipe, may solve gallery issue...

[Q] Anyone having issues mounting their tablet MTP

Is anyone having issues mounting their tablet via USB. If I check off Camera (PTP) I get access to my photos in my Windows Explorer, but when I check off Media (MTP) windows acts like it doesn't exist. ADB can't see the tablet either, but once I check off Camera (PTP) ADB can see the tablet... I'm using a windows 8 computer, has anyone heard of this happening, or is it happening to any other computers?

I have no issue using MTP. Did you install the driver from google?

You have some old driver that is blocking access.
Use device manager to remove the device and driver then reboot and try again using the Google drivers.

Yes. It is fairly typical. I had same issue on Windows 7 x64 and lived with it for a while.
Finally, I decided to fix it by uninstalling the drivers and reinstalling. It took about an hour after trying all sorts of tricks. There are tricks in quite a few threads here on xda. I'm not sure any one thread fixes every problem. So I found the solution was trial and error.
After messing with driver for a couple hours, serious waste of time, I got MTP working once. As a confirmation check I uninstalled the drivers once more and let the drivers reinstall on plugging in the device. It broke again, back to PTP. LOL
Not giving up, I tried again the next day and finally got MTP working again. This time I uninstalled drivers again, and the correct drivers reinstalled on device plug in. Since then everything has been great. I get both MTP and PTP working great.
I would try sfhub thread ideas and search around for a couple other ideas too. It will eventually work, but you have to isolate what exactly is the problem on your Windows 8 PC. Sometimes you are missing just one thing, sometimes Windows automatically messes with you.
Good luck.

I have no issues with Win7x64. Worked first time and every time since. Sorry...
