How do you load music & other files on this thing?

I plugged it into two different windows XP computers with the USB cord, but nothing shows up on my computer. I get some weird error on my phone, something like "PC connection unavailable ... blah blah blah ... idle screen ... blah blah ... close applications." I think this might be because I'm using LauncherPro. Why can't I just get a simple vanilla android build?

there are custom usb drivers, look for them in the how to root thread in android development subforum. After you dl them extract them somewhere and open up device mgr. U should see a usb device with a ? over it. Rightclick it and select update or install. Tell it that you want to select the location of the drivers and point it to where you extracted the drivers. You'll want to use the x86 ones if you have an intel 32bit winxp and the amd64 if u have an amd processor running windows xp.

OK.
Bring up your Settings pane and select Applications. In the Applications screen, select USB Settings and select Mass Storage. Now, when you connect the handset to your computer, pull down your notification bar and select USB Connected, it will bring up a prompt about mounting the volumes - press Mount. In the future you will just need to plug it in and mount the drives from the pull down menu.
You should be good to go. If not, try installing the Captivate drivers.
Also several people have had issues with plugging the Captivate into the front USB ports on their computers, and switching to a rear USB port fixed it - so give that try if you are still having issues.

Thanks! That was the ticket! Wow, am I relieved. Also, for any other newbies out there, it seems like you can just throw files at the drive and android will find them. I put mine under "SD", but I have a hunch you can just put them anywhere.
Also, I refuse to install any drivers for this phone, which is why I just used it like a generic usb drive. I honestly loved my iphone, but I hated that you had to use itunes with it. If I have to install anything on my computer to use my phone, android just lost an advantage to the iphone in my eyes.

I had this same problem and there is no way I could it plug into the back so I tried the USB plugs on my monitor and thankfully that worked. I don't know why this phone was made so difficult to connect to the computer and have it recognized as storage.

Yeah, I installed them trying to figure the damn thing about but I suspect they may only be needed if you want to tether via USB - not sure though.

Weird, isn't it? It's inconvenient to have the cable in the rear, but it was the only way I could get everything to play nice. I'll have to pick up some spare cables for the charger, work, etc so I don't have to reach back there and pull it out when I need it elsewhere. Not a bad idea anyway.

[Q] Zune no longer recognizes my phone

Hey there,
I'm having issues trying to sync my phone with my computer. When I connect my phone, nothing happens, Zune doesn't launch, and when I open it, it doesn't show my device as connected. I've tried everything I can think of, different USB ports, rebooting both the phone and my pc. I'm running windows 7 64 bit, and it was working before. Anyone know what's going on?
Thanks for the help!
p.s. I tried uninstalling the drivers for the device, and upon reinstall my computer said it was installing drivers for "Microsoft USB Sync" thought that was weird...

try making it forget your device (don't have your phone plugged in). to do this, click on the phone icon in the bottom left of zune, click view sync options, and then on that screen click forget device.
after this, try and connect it again.

Didn't work, i plug my phone in, and Zune still says I have no device connected

does your computer make it's sound when you connect the phone (device detected sound)? if not, you might need to reset your phone (settings > about > reset phone). if yes, does it show the eject icon in the notification area (system tray)?

yes, it makes the sound, and yes it shows the eject icon... this is very odd

I had this problem too. When i went to the Device Manager, it showed unknown device when i plugged my phone in using the USB cable.
Here is what I did (Windows 7). If you see an unknown device, right click it and select Update Driver Software. Click Browse my computer for driver software, then click Let me pick from a list of device drivers on my computer. Then click on the Have Disk button, then browse to C:\Program Files\Zune\Drivers\Zune and select WMZuneSerUSB.inf. Then select Windows Phone 7. Hit Next and you should now see your Unknown Device show up as either Windows Phone or the name of your phone under Portable Devices in the Device Manager.
Actually, I forget if it is WMZuneSerUSB.inf or Zune.inf, so you'll need to try both.
Hope this helps.

I had this problem with my Samsung Focus.
Try using the cable that came with the phone, not another one...
That is what worked for me..

Nothing seems to be working, I may have to reset my phone, which i was hoping to avoid...

Did you perhaps use the hidden Tethering feature? If so, then change that option back to "Zune sync" and you're done. It is not possible to use your phone for Zune sync and tethering at the same time, for now.

Now that you mention it, I can't remember if I did that on this phone, or my last optimus that had to be returned. What exactly do I need to do to change that back? I totally forget the process...

Dial ##634# to go to "Diagnostic mode"
Then enter *#7284# to go to "Micro USB Test"
You then have 3 options to choose: "Zune Sync" (default), "Modem, Tethered Call" and "Modem, USB Diag". Change it back to "Zune Sync" and you'll be able to connect with Zune on your PC.

Anyone else having this problem? Zune doesn't recognize my WP7 phone on a laptop with Win 7 x64, but same phone+cable works on a laptop with WinXP
The Win 7x64 laptop does connect to the phone - I tried the above tethering change and was able to pull files from my WP7 storage - but when I switch it back to Zune synch it doesn't work.

Is this specific to Samsung models? I can't get to the micro USB test on my lg optimus
EDIT: Problem solved, I had to switch back to MS COMPOSITE, and now it works fine.

Hmm yeah I have this issue on my HD7 with my PC running Win7 x64.
The phone connects fine on both ends (sound on both, phone charging, shows up in Device Manager as HTC HD7), but the desktop Zune software often does not show it as being connected. Restarting the phone and PC generally doesn't help-- just have to wait a few days until they start syncing again.
The sync setup seems really flaky (like the earlier days of ActiveSync).

i have the same problem...

Are you using virtualisation software? It's USB arbitrator modules for forwarding devices might have messed up things. This happened over here before with VirtualBox.

Exact same problem with Win7 Ultimate x64. Device manager saw my phone but zune would not.
I did the steps above to change my phone to usb tether, rebooted, then back to zune zync, rebooted, and now the zune sees my phone.
Thanks for the help.

[Q] drivers disappear?

after i rooted my phone, i pluged in my device into the computer and click mass storage. but it dosent show up on my computer. i havent changed anything on my computer so it could be something on the phone? would usb debugging make a difference cause i have that turned off?

first thing, try rebooting your phone and computer. also make sure that your memory card is mounted (settings>sd and phone storage). secondly, are you SURE that the computer isnt recognizing it as a drive? Co to My Computer so you can see a list of available drives and see if its in there. Sometimes you wont get the popup on your screen.
Drivers normally wont just disappear unless there was some type of system error. You can also go into device manager and make sure that it shows up when the phone is plugged in. If that doesnt fix it to avoid a long drawn out troubleshooting thread, try picking a day before you rooted and go to system restore and select a recent restore point. If you do that and it still doesnt correct the problem, then it may be time to troubleshoot the phone
and USB debugging wont stop your computer mounting your phone as a drive. When you pull down the notifications panel once plugged in, you should still see the option to use a USB drive whether USB debugging is enabled or not

Thanks man yea I figured it out the system fixed the drivers so it connected

Nexus 5 Is not seen on PC!

For some reason, my N5 can't be seen on my PC. It doesn't show up in device manager, and the phone itself doesn't prompt me for any kind of connection (mtp for example). I think its a driver issue, does anyone know a way to help?

Same thing with me. But I screwed something up.. I was having trouble with the drivers so I used the first guide on theandroidsoul that was posted in the stickied how to unlock the bootloader thread. After I uninstalled the driver in device manager on my win7 computer like it says in step 3 of the guide my computer no longer detects my nexus5 or nexus4. They both charge but they aren't listen in device manager/no connection sound when I plug them in.
I have restarted my computer a few times. Made sure usb debugging was on in the developer options.Toggled MTP on and off. I also checked on another computer that it wasn't the usb cable.

Same here! anyway to get those old drivers back?

Okay now this is weird. Anyone reading this must think I'm and idiot. I know for sure it wasn't working before. I used 3 different usb cables on both n4 and 5. I wiggled them and held them in place leaning in different directions just in-case the usb male end wasn't making the connection. I just tried the n4 one more time and it worked, then tried the n5 and that worked too.

went to device manager when i had my nexus 5 hooked up and it show nexus 5 with a exclamation mark so i uninstall.but usb debug has to be on.
now disconnect phone and turn usb debugging off .
after u do that connect phone and click on storage and click on 3 dots on corner and select mtp and drivers shoud install and it should work.

I tried this a couple of times! PTP but MTP isnt...

If anyone was playing around with NRT or other similar tool kits & had universal USB drivers installed to unlock, install custom recoveries & root, that could've "wrecked" other drivers & settings on it (Windows 7 ??) - one way to restore the connectivity to the N5 is to use MS's System Restore, go back to the earlier date - it should be successful restoration after it finished & reboot. Strange & hard to explain, but it worked & it was too late at night for me while helping out to work the logics behind it. The laptop normally see the N5 upon usb cable plugging in & open with the prompt to read the folders & files.
No matter what, usb debugging off & on, it was no good - only recognize the N5 when switched to Camera (PTP) mode & can only see 2 folders, normally - MTP or Media Device is the default setting & all the "SD" folders visible ...
Once reconnecting via usb cable, let it sit for 1 or 2 minutes so that the drivers can "wake" up and install & recognize the device(s).
Grrrrr, upon further checking with my old faithful HTC, the desktop OS seemed to have "corrupted" the USB drivers and now it is only reading it as a Removable Drive & not as HTC device.
I would go back & follow Littlegreenalien's steps to see what happen and then attempt a System Restore, time to brew up some coffee this weekend & deal with this minor challenge. Wondering if it's the new KitKat thing - and, sidenote, both N7 (2012) and N5 are generating random bug reports even on rooted stock rom & kernel. :cyclops:

Didn't think of a system restore! Man that's a good idea, I'll try it when I get home. My N5 also generated a bug report around when I was trying to fix this problem!

This was the answer for me as well. All android drivers need to be uninstalled, then let the computer detect the N5 and install drivers

Let us know how it turned out, look at Window's Control Panel, do you see Portable Devices & under it, it should say Nexus 5, and click it to see the drivers (total of *.dll's and *.sys on my W7 Ultimate 32-bits OS)
Now that everything has been restored, "Auto Play" popped up after a pause of few seconds with usb making connections. Rebooted the laptop & now it's seeing the HTC again after auto reinstall drivers.
Just in case anyone, off-topic slightly, if anyone is playing with their Nexus 7 sideloading KitKat & small OTA patch, you should also see Android Device under the Control Panel & the Google Nexus 7 ADB Interface - with USB Debug enabled. But, with the Nexus 5 connected, it is showing "Google Nexus 4 ADB Interface" while showing it as N5 under Portable Devices ... what the heck !
I'm going to leave it alone for the time being, if it ain't broke & is working, leave it alone & let it be. Call me lazy, TGIF - not going to go thru the routines of uninstalling drivers, rebooting & all that and ruin the webcam, camera & other usb drivers loaded on the laptop. I can run ADB and Fastboot commands, etc. just fine now.

The simplest and shortest way to connect google nexus5 with PC as MTP(Media device)

When I plugged it, there wasn't any yellow exclamation mark within Device Manager. So for me, the drivers were OK. But the device was not listed within my Eclipse DDMS. After a little bit of searching, it was just an option to change in the device settings. By default, the Nexus 5 USB computer connection is in MTP mode (Media Device).
What you have to do is:
Unplug the device from the computer
Go to Settings -> Storage.
In the ActionBar, click the option menu and choose "USB computer connection".
Then select Media device(MTP) or Camera(PTP) based on your requirement...
Plug the device and you should have a popup on the device allowing you to accept the computer's incoming connection..
I hope this will help!

Can't connect Pixel and Windows 10.

When I plug in my pixel into my Windows 10 laptop, neither device responds. This means that I get neither the AutoPlay pop up on the laptop, or the USB option notification on the phone.
What I have tried:
Plugging into a Windows 7 laptop; the AutoPlay box appears on the laptop, the USB options notification appears on the phone
Tried all USB ports on the Windows 10 laptop.
Confirmed that other USB devices appear correctly on the Windows 10 laptop
Any thoughts?
Guidance?

Have you installed the latest fastboot and adb. If not download them here and make sure to add the folder containing the files in your path or unzip the files to your Windows directory. I had the same problem on Windows 10 when I was running it and that fixed it for me.

Check in Device Manager to see if the Android device is listed. If it's listed but is indicated as not having a driver loaded, you can always download the latest drivers from https://developer.android.com/studio/run/win-usb.html and the latest platform tools at https://dl.google.com/android/repository/platform-tools-latest-windows.zip.
Extract the drivers, right click the non-working Android entry in Device Manager, point it to the main folder you extracted the drivers into and see if it'll load the drivers. This may not be the problem but worth a try. Even if it doesn't solve it on Windows 10, try the same thing on Windows 7. Windows 7 may be too old that it won't automatically find the correct necessary driver like it should on 10.

Simple enough? Hope it works for you.

thanks, but no luck
@Misterxtc thank you. Already tried. No luck
 @oirraW the device does not appear in Device Manager.
 @bobby janow I am familiar with Google. Believe it or not, I even went to page 3 of the search. The solution you found has been tried and does not work.

Install Linux, no drivers to install, it just works
Some dumbed down versions you might have to do
apt install adb fastboot
You never have to reboot, only if new kernel, and that too is going to change

Until you can get it to show up in Device Manager, there's nothing else you can do. Try a different USB port? Reboot the PC? Try a different cable if you have one? I can't think of anything else to try other than reinstalling Windows. I haven't had any trouble on Windows 7 or 10.

@piperx might be extending my tech skills a little too far. @roirraW "edor" ehT that is a pity.

clutching at straws but worth trying as tell the computer sees the phone and lists it you are stuck so enable developer options then enable usb debugging and set usb configuration to MTP then with the phone connected and the phone unlocked reboot the phone keeping the phone unlocked all the time.

It's not the use of it, it's the installation of a dual boot that doesn't take up too much space.
I did go have a look, suggestions are Ubuntu or Mint. Would like the smaller one.

Make a bootable USB of each distro you want to try. It's super easy with Rufus. This way you can try it without installing anything or wasting blank disks. I like Mint, it's basically Ubuntu with a face-lift.

I haven't actually done anything to fix it except to upgrade my phone and laptop.
Phone is on Android 9
Windows enterprise is on 1709
Now when I plug the phone in, I get the options on the phone and laptop. I choose File transfer and it works.
Not really helpful. But sometimes it seems apathy solves all problems.

If Pixel phone on connecting to windows only shows up in File Manager when you choose PTP option in the Pixel’s USB Preferences (and disappears from Explorer when you select File Transfer), you will be restricted to the DCIM and photos directory, thanks to the miserable ADB Composite driver that keeps getting updated or installed for morons who can’t handle full drive access in their pixels. ADB and PTP were designed so idiots would not need to worry about anything other than their media directories on their Pixel phones.
For anyone above age 4, full access to the Pixel SD memory is preferred. To fix the above, it is necessary to ditch the ADB drivers and get the generic MTP drivers back instead in Windows. Here’s how I did it on a Pixel 4XL with android 12 or 13:
Unplug phone, make sure Developer’s Options is ‘on’ and that USB Debugging is ‘on’
Ensure that in USB Preferences, it is defaulted to File Transfer/Android Auto and NOT to PTP
In Windows, open Device Manager, View, and check ‘show hidden files’
Then, open View-Devices by Type-Portable and delete/uninstall your Pixel phone, all of them if there’s more than one.
Then start looking for anything that says Android or ADB, and delete every shred of anything that’s an ADB Driver interface, whether composite, USB, whatever. If it has ADB in it alone or under LeMobile or Acer, it’s got to go. Uninstall and delete them
Plug in phone
Under Device Manager-View-Devices by Type-Portable find your Pixel device. Right click and Update Driver. Then, click Browse My computer, then click Let Me Choose, and then click MTB USB Device… I picked the bottom-most one
That’s it, it should work
