[Q] Galaxy Nexus MTP driver issues in Windows XP

Hi guys,
I wonder if anyone can help with this problem?
,
I'm having trouble hooking it up to my PC which is running XP.
When I chose to connect as either "Media Device MTP" or "Camera PTP" I get an error message on the taskbar of my PC:
"USB device Not Recognised. One of the USB devices attached to this computer has malfunctioned , and Windos does not recognise it. For assistance in solving this problem, click this message."
I click the message and get taken to the list of USB devices with one in bold stating "Unknown device", I click on it and try to update the drivers etc but PC is unable to instal newer drivers.
I think I've narrowed this down to an MTP (Media Transfer Protocol) driver not being installed on the PC, so have installed Windows media player 11, Kies, Samsung PC Studio 7, tried searching the net for drivers, even tried installing Galaxy S2 drivers and none of them work.
Does anyone know what else I may be able to try, or can someone tell me where I could get the correct driver as this is starting to drive me nuts...
PS. I have hooked up the Nexus to my work PC (running Vista) and was recognised withing seconds, so is not a faulty phone
Thanks in advaance for you help!!

Is there no way I can get the drivers in XP?

Hah, you posted what I managed to resist writing. I thought to myself 'someone's bound to bring that up'... Right on time!

Just get WiFi file explorer PRO and sync through wifi...but I'm quite sure that you can get MTP to work on winXP.

Can't really help you with the Galaxy Nexus since mine hasn't arrived yet but for my Galaxy Tab 10.1 I didn't install any driver (honeycomb also only understands MTP). I let windows install all the drives automatically, had to restart a couple of times but in the end I had a working connection with no Samsung crap like Kies installed.

I've got this as the work around at the moment, but finding it a bit laborious having to transfer one file at a time.
Finding that Samsung website is quite useless - only has the User guide as downloadable PDF.
Microsoft website is even less helpful...!

You can transfer as many files as you like....up.
And to be honest you can also try using an FTP server, it works very well and then you can browse your phone easily.

Is that with XP?
I thought I was getting there after installing WMP 11 as I got a message stating "Galaxy" when I connected the USB cable, but it still didn't work fully.
A couple of re-boots later it resorted back to "USB Device not Recognised"
Hope the Nexus conmects for you when it arrives

Do you mean that you can upload multiple files in one go with Wireless file transfer Pro?
with music for eg. I'm having to do one track at a time?
Will look at the FTP servers now, any recommendations?

Sorry no, it was something worse, Vista.
If you got xp to recognize it as "Galaxy" you should be on the right track. I remember that being the first device in Vista too. The auto update feature installed various Samsung updates, always after the device couldn't be started and almost all of them required a restart. But about five of these updates (and restarts...) later it connected correctly. No Samsung software necessary.
Don't know if that was dumb luck but I'm not complaining.

I have missing MTP driver on my WIndows XP laptop for work (I use Win 7 at home) is there any solution to this yet?

Try this.
It will install the Media Transfer Protocol Porting Kit (MTP drivers) on Windows xp and should allow the device to be recognised.
I uploaded the file (which I downloaded directly from Microsoft) so you dont have to validate first. Download it *HERE* and install.
Let me know if it works for Windows xp and I will add it to my fixes section im writing.
Mark.

Thanks, Mark,
I did find and download that file earlier but it didnt work. However, as my work laptop is subject to Group Policy, it may still work for others. I do have local admin rights on my machine so I wouldnt have thought it would be a problem but we always get quirks with our corporate builds.
I have found other references on the net to a file from Creative called "fixup.zip" which apparently includes the MTP drivers (tweaked to also allow recognition of creative devices) but I cant find anywhere to download it from.

after a little searching with Google i found the answer
so my laptop runs XP (because i shoot tethered to my Canon Camera and i know it works) and i use the laptop to sync my phones (also collects my e-mail etc) and i stumbled on this thread when i was searching for a solution as to why MTP failed to install with my new Nexus..
the solution is
to install Windows Media Player 10! once i did that, BAM! i can see my Nexus in the explorer window with the rest of my drives

New "known issue" - samsung!
I had issues trying to get the device working on 3 computers yesterday (Win 7, Vista, XP) , with only interment luck.
I got to Samsung Level 2 support, at 2pm EST, I was his first G-Nex call. We tried the Samsung driver, updating WMP to v11 on XP. Best I got was it to open sometimes (best after a GNex Reboot or after almost shutting it down: ie. holding power button in ant hitting back arrow). It opens best on my Vista PC (one I hardly use...); Sometimes I open it and get no further than the device level (GALAXY NEXUS); if Internal Storage eventually shows up, you may be able to get in; then you MAY be able to transfer files to the folders.
I got a call back from SAMSUNG Level 2 today: "THERE IS A KNOW ISSUE IN THE MTP LAYER OF THE PHONE; THERE ARE ISOLATED CASES OF PROBLEMS LIKE YOURS; SAMSUNG & GOOGLE ARE WORKING TO RESOLVE AND ISSUE A MAINTENANCE RELEASE". (As close as I can quote this.) No, there was no estimate of WHEN this would be released, but I'm hoping soon, as it is a pain and major issue for us "isolated" cases - why me?

I found that MTP does not work correctly on winxp without Windows Media Player 11. It appears to work kinda with WMP10, but not the way you would expect.

Fix
I was pulling my hair out trying to get my new verizon galaxy nexus connected to my pc running windows xp to transfer files. Finally I figured out what the problem was for me.
MTP is tied to windows media player somehow and you need to have the new version of windows media player installed for it to work. Until I did this I was getting an error when a plugged in my phone about the required files not found in the INF file or something.
1. download new version of windows media player.
2. You need to download the samsung USB drivers from samsungs website...I would post the link but I am not allowed.
make sure you click the tab for software...it defaults to manuals and doesn;t look much like a tab at all. After that mine worked beautifully although the MTP transfers seem extremely slow compared to the USB mass storage connection my droid 2 had.
Hope this helps someone else out there!

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!!!

[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

You tried a different USB cable? Just a thought...

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!

Maybe usb-debugging is on and your PC has a driver Problem with usb-debugging?
Else: Go to device management and look if the device is properly shown also galaxy nexus.
Else2: I don't know. Maybe open the window and throw your PC as far as you can

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...

Trouble connecting HTC One to laptop via USB

Hello,
I am having problems connecting my brandnew HTC One device to my laptop which is running Windows 7 x64. When connecting the device via the USB cable that came with the HTC One wrapping the cellphone indicates that it's battery is being charged and a small red LED at the top speaker is switched on.
I tried all different USB ports of my laptop, all with the same outcome.
I installed HTC Sync (most recent version), yet no sign that the celly is linked to the laptop - except for the phone displaying that its battery is being charged.
Google then took me to these forums where I stumbled accross this collection of drivers. After removing HTC Sync from the laptop I installed both, HTC_BMP_USB_Driver_x64_1.0.5375.msi and HTCDriver_4.2.0.001.exe
I also checked the cellphone's dropdown menu (when you slide your finger from the display's very top to bottom) to see if there's any USB connection shown, yet nothing!
What am I doing wrong? Can I safely assume its a driver issue hence my sister's iPhone5 connections without any issues via any of the laptop's USB ports (2xUSB2.0, 1xUSB3.0). Any help appreciated!
Regards

go to my computer on your laptop and see if HTCONE is there, click on it and will show your internal card.also check in settings that mtp is checked
make sure usb debugging is enabled, also. (in development settings)to get to development settings tap on build number (in about phone)5 times i think to enable development settings.

I can not find HTCONE in the "My Computer" window. Currently I am running the latest version of HTC Sync (64bit) downloaded from htc.com. I just enabled the USB-Debugging by checking the checkbox "USB-Debugging" in Settings->Developement Settings on the cellphone.
How to make use of the debug function/where to find the debug output?

I plugged the phone into 3 different USB 2.0 ports and waited up to 20 seconds every time. I do not hear the sound of a device being connected that usually occurs when plugging in some device via USB and no tooltip is displayed at the bottom right of the screen. HTCONE is not appearing in the "My Computer" window either.

There is no option "mtp device" in the phone's dropdown. I just did a complete reset on the celly to see if that helps, yet no effect!
I'm gonna try that last idea of yours and remove HTC Sync from the computer and plug the phone in and hope the proper drivers are installed. I'll post a status update when I'm done.

Uninstalled HTC Sync and HTC * Drivers, plugged phone into the computer, still the same issue!
If anyone has anymore suggestions please let me know, meanwhile I try it on a different computer.
Thank you for your troubleshooting ideas though, I'll let you know if I found a solution to this problem.
Greetings

UPDATE: Tried connecting it to a computer running Windows 8 x64, installed HTC Sync before. Still nothing but the battery charge indicator!
Trying a friend's USB cable tonight.

Okay, it finally worked using my friend's USB cable who bought the same cellphone, HTC One, in a store in Germany. My celly is bound to a contract a friend of mine ordered via the internet on a http://www.preisboerse24.de/.
The first weird thing we noticed was that there was already pictures from a former owner of the cellphone in its camera roll. We guessed that someone ordered it at the same seller and sent it back after a few times of usage and they simply forgot to put it back in its original state.
Now that the USB cable aint working we suspect it might not be original at all and will call them for compliants on monday.

I corrected a similar problem by tapping on "Buiild Number" in About>Software Information>More until I unlocked developer.
Then proceeded to Settings>Developer Options> and turning on USB Debug.
You might need to install the following drivers if it doesn't work for you:

[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...

Make sure you are using the usb cable marked Asus on one end that came with the Nexus 7. I had the same problem because I was using another usb cable. They are not all the same.
