[Q] Help: GT-P6210 not detected by W7 32 bit Enterprise at all.

Hi,
Quick background: Former sys admin with some Unix experience. Already own a Toshiba Thrive rooted with CWM. Gave that to the wife and got me the GT 7+. Read the forum here prior to buying. Rooted on day one.
Stats: GT-P6210 Build: HTJ85B.UEKL1 P6210UEKL1
PC: Windows 7 21 Bit Enterprise SP1
Kies: Kies_2.1.1.11124_17_6
Later on the first day, after installing aps, I installed latest version of Kies and plugged it in with the supplied usb cable in order to transfer some files to my Sandisk 32Gb microsd. Kies already running and debugging off as per the instructions. Results: Tab plays a notice and I see the MTP connected icon. My pc does NOTHING. No sound, no notice, Kies does nothing.
I unplugged and tried the other 3 ports. 2nd port gives me same result and on the 3 & 4 port I lose the tab's MTP notice and it begins charging.
So, this is what I have done in order:
1. Re-installed Kies--->same result. No MTP notice on tab.
2. Debugging on--->same
3. Tried in on my room mate's W7 machine---> Alas! I get a driver installation and I am able to see both drives. I quickly unplugged and thanked him.
4. Cleaned my pc by:
a. Deleting all USB controllers
b. Deleting all USB installations on registry (HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumUSBSTOR)
c. CCLEANER the whole system.
d. Turn off. Pull off battery. Press power button to drain motherboard.
e. Restart and re-install USB controllers.
f. Restart again.
5. Plug in again--->Tab plays a notice and I see the MTP connected icon. My pc does NOTHING. No sound, no notice, Kies does nothing.
6. Pull my hair, bang my head, wished I would have kept the Thrive. (just plug, and drag and drop)
Left it plugged to the pc overnight. Next morning I see the found new device on systray and it is trying to find drivers. I quickly open Kies and see some activity as it tries to connect. and after a few seconds, it stops. Result: No drivers installed, no Kies recognition, no drive letters, nothing.
8. At this point I ask my room mate to let me plug in on his pc to see if he still sees it and nothing happens on his pc.
9. I wipe the table back to stock.--->Tab plays a notice and I see the MTP connected icon. My pc does NOTHING. No sound, no notice, Kies does nothing. Then after I tried other ports, it begins charging and I lose the MTP notice.
10. I re-roo,t reconfigure the beast, and do a backup. Tablet is running smooth as silk, but it never connects. This all happened in the last three days.
11. Last thing I did, as I am writing this with the tablet plugged in to the pc and MTP notice on, was to un-mount the microsd and remount. MTP re-initializes and it does nothing.
I may be suspecting a cable and unfortunately, I am in no position to get my hands on another one in a timely manner. At this point, I could reflash back to a stock firmware, send back to amazon and wait for another one to come in three to four weeks (I am deployed to a remote area) and I just don't want to do that.
The tab runs great. Love the size and speed. I guess I can continue taking out the microsd card out every time I want to add a file, but I am afraid that it may eventually end up ruining the card and possibly the tablet.
Please help. I have scoured the internet, but all I ever find is solutions that I already have tried.
Thanks in advance,
Sal

you could use adb over wifi.. There are a few apps in the market for this. Does adb recognize the tab when its plugged in via USB?
Also try Android commander, it is a GUI based adb server, you should be able to navigate to sdcard/extstorages/ and your external card should be there

You could also use a file explorer like Root Explorer and Dropbox to transfer files back and forth.

Have you tried a different USB port on the PC? like one round the back.
Also, try without the sdcard in.
Ticked/unticked USB development/debugging on the tablet?
If it works on another computer though it would suggest its your own PC which has the problem, not the tablet.
tried with Linux on the same PC?
Does Odin see the tablet when in download mode?
if you have clockwork mod recovery, doesn't that have a USB mount option ? It does on my gs 2. My tab isn't with me to check.
Oh and kies has an option to reinstall the driver. Did you try with the older version of kies again?

I'll try adb. I will install it and see if how it works. Time is tight so I will report later.

I have done all that you mentioned with the exception of Linux and Odin. I am not going to get into Linux as that would start a whole other project. I will install ADB to see if I can force the drivers.
I just tried the CWM mount USB mount but get "E: Unable to open ums lunfile (No such file or directory)"
Also, on my friend's pc worked once but not after that.
I will continue to explore the ODIN suggestion.
Thanks,
Sal

I use ES Explorer (wonderful app!) now. My end-state is not to have to remove the card every time I transfer a file.
Sal
EDIT: Sorry, I see now the dropbox suggestion. Yes that would work for smaller files, but I am not sure that dropbox can handle movie size files. It would be a last resort solution.
Thanks,
Sal

Adb is probably going to be your best bet. It can be a pain to set up at times, but in the long run is a must have for any Android device. Kies normally installs the drivers that adb uses, so hopefully you can get them to install. If it still doesn't work I would suggest swapping it out for a new tab, as much as that sucks. If you need help, I constantly check these forums, so I should be able to provide some support

Well, got ADB installed and running. Set the path and ran it. Plug the tab with debugging clicked on, and got "MTP connected" on the tab's screen. At this point I am excited since I never seen the "MTP connected " on debug mode. I typed the "adb devices" command and got "List of devices attached" ___________________.
Yep, blank. Obviously the pc is not seeing it. My conclusions are the following:
1. Bad cable
2. Bad device
The fact that it recognized once on my room mates' pc and then none at all, and the fact that it was recognized on my pc for a brief random time, then it means that the device can't handshake with the motherboard and thus is a communication issue.
I'll try my luck with Samsung tech support and see if they can replace the cable.
Just thought of something, would installing Windows XP Mode under a Windows Virtual PC recognize new devices or just feed from the Windows 7 library?

Hmm, that is strange.. I was new to samsungs and when I tried to root it it took me a while because I didn't know that kies installed the drivers. After I installed it though adb devices showed my tab connected...

I placed the tab on download mode and queried it from adb and got nothing. I then queried it via ODIN3 and got no response as well.
I have come to terms that it has to be the device or the USB cable. Just ordered two (yes, two) different type cables to test out the theory. If they don't do it, then I am sending the tab back to Amazon.
It takes about a week to get stuff shipped where I am at so I'll check in later and report.
Sal

Just an update.
I bought a cheap cable from Amazon for $ 3.31 US to test the cable theory and guess what? It worked.
Curse you Samsung for your lack of QC with your cables. I have read throughout most of the forums (not just this one) and it seems that cables for these devices are notoriously finicky.
While on the one hand, I am glad that I got a cable that works, Samsung owes me over thirty hours of my life that I had to spend on troubleshooting a brand new device.
The part that I hate the most is that when I tried to contact Samsung's tech support, all they kept telling me is that it must be my pc even after I told them all the troubleshooting that I had done. Yes, they played the blame game.
My Toshiba Thrive worked right out of the box with a standard micro usb cable.
Ok. Rant off.
Sal

Glad to hear you got it working. Personally I have a ftp server set up on my comp that I use to transfer files back and forth. Much easier IMO than having a cable every time I need something transferred

[Q] No USB connectivity.

How can I fix my problem of 'No USB connectivity' ?
My Samsung GS3 has stopped giving me the notification that I connected to my PC. It still charges, but I can't access my files. It's been happening for a few months. When I cable up, after a second, it chimes audibly (pong-ping), but the pitch fork icon for USB never shows, there is no notification, the PC never does anything. Drop box works, Wi-Fi works, NFC works, Phone works. Samsung model SCH-I535 running Android 4.1.1 on Verizon. I have not rooted, or ROM’ed but this may take me past that brink.
I've tried::
Numerous PCs and USB cables
USB debugging (& Stay awake & Unknown sources) checked and unchecked
Unmounted & remounted SD card
Asking the PC to look for new hardware
Removed and re-installed PC drivers both from Verizon
(Verizon_Wireless_I535_GSIII_Samsung_USB_Driver_v1_4_6_0.exe)
& from “Samsung GS3 Int ToolKit”
(SGS3_International_ToolKit_v6.0.exe)
:: but nothing has fixed it. :crying:
Please don’t tell me to use a Wi-Fi app, Kies, All Share Cast, or S Beam. I want my phone USB fixed.
Thanks;
SparksGuy

What are you expecting to see when connected? The new Android o's doesn't mount the device as a drive letter - you have to access it via MTP. This means you won't see it as a drive. You need an MTP capable program to sync, or you can see the contents within the "portable device" entry.
Without proper, working MTP drivers, the phone may not show the connection. Under XP I had many issues getting the driver to work. I think other windows versions have similar issues. I had to force-load the drivers from the "eclipse" (I think) sub folder after extracting the files in the installer.

I fixed this by doing the following:
1. Reboot phone into download mode.
2. Plug phone into PC.
3. It should install some drivers at this point.
4. Remove phone from PC and remove battery to shut off phone.
5. Put battery back in and boot phone.
6. Plug phone into PC.
7. Profit??

Working, thanks!

As I tried 'download' mode, it worked, sort of, like you said. My PC found new hardware and installed MTP and ADB drivers. My procedure went more like this:
1. Remove phone from PC and remove battery to shut off phone.
2. Plug USB cable into PC.
3. Plug USB cable (other end) into phone.
4. Put battery back in and boot phone but…
5. As the phone boots, hold down Volume up and down
6. This should reboot phone into download mode.
7. PC should install some drivers at this point.
Phone was in safe mode, but another reboot changed that.
Their must be some magic in that old silk hat you found. Opps, sorry, wrong song. :victory:

[Q] Trouble connecting Nexus 5 to new laptop in MTP mode

Not sure how many would read such a long post for a question, but here goes...
Any help is appreciated!!
1. Problem
In short, I plugged in my Nexus 5 to my laptop in MTP mode, it does not show up in "My Computer".
I just wanted to transfer files to my phone via USB, not even using ADB yet.
I have yet to solve the problem after googling around for a bit.
Relevant XDA threads that I remember reading are this, this, this, this and this.
I have tried numerous combinations of (un)plugging my phone / (un)installing drivers / rebooting my laptop and phone / switching usb ports / turning USB debugging on and off / connect in PTP mode / ...
As a workaround, I am now transferring files using the AirDroid app, which is really convenient with acceptable speed.
Still, it would be nice to know why the problem occurred and see if others have similar problem.
Below I will describe the devices I have on hand and more details on the failures I have encountered will follow.
2. My Devices
A. an old Galaxy Note
B. the new Nexus 5 with the stock micro USB cord
C. new laptop
- 64-bit Windows 8 Pro (not upgraded to 8.1 yet)
- only USB 3.0 ports
D. old laptop
- 32-bit Windows XP Home
- only USB 2.0 ports
3. Details
Scenario A. Nexus 5 not showing up in "My Computer"
Naturally, the first thing I tried is to simply plug my Nexus 5 in to my new laptop. I was used to Android devices working just like that!
However, my Nexus 5 does not show up in "My Computer" after a loooong wait.
On a closer look, my Nexus 5 (only) appears in the "Device Manager" under "Portable Devices" as "MTP USB Device".
It shows my device to be "working properly". However, I cannot uninstall/disable it when my phone is plugged in (normal?)
Frustrated, I decided to unplug my phone. I have the option to "Unplug Nexus 5" under "Safely Remove Hardware", but the operation always times out, so I simply unplugged it.
Then I tried with my Note using the same cable. It works flawlessly either in MTP mode or Mass Storage mode.
Scenario B. Nexus 5 shows up, but is really sloooooooooooooow
At some point, I turned on USB debugging.
With USB debugging on, my phone appears under "Portable Devices" as "Nexus 5" (and in some other places according to what drivers I have installed).
I was quite pleased for a few seconds as my Nexus 5 now shows up in "My Computer"!
However, it took a few minutes to list the folders I have under my phone's internal storage.
Attempting to copy a 12MB file to it gives an estimated time of over 2 hours.
Scenario C. Success?
After tinkering with it for some time to no avail, I was beginning to worry if I have gotten a defective hardware.
Then I remembered I had an old laptop stashed somewhere, so I tried connecting my Nexus 5 to that.
And... voila! It works without a hitch (MTP mode, USB debugging off).
A maybe useful note is that I have used both the old and new laptops to transfer files to my Note before.
4. Possible causes
While many seems to have solved the issue by simply unplugging and letting Windows reinstall the drivers, I have no such luck.
I sincerely hope that it is not due to any hardware defects since
a) my Note can talk to my new laptop through the same micro USB with no problems, and
b) my Nexus 5 can talk to my old laptop.
I feel that this is a driver-related issue but I am not sure.
Is it possible that there are compatibility issues with using USB 3.0 port (which should be backward compatible...) or a 64-bit Win 8 Pro?
Any help is appreciated!

It is so strange..
I just bought a USB 2.0 hub and connected my phone to my new laptop through it.
Guess what... it works perfectly!
Apparently my problem was that my new laptop only had USB 3.0 ports for me to test on?
Doesn't make sense... thought 3.0 is backward compatible and my old Note works on it!
Maybe I'm missing something but I'm happy it is solved for me now

This solution worked for me. Go to http://forum.xda-developers.com/showthread.php?t=2512549 and see post #5. Be sure to thank n7of9 for the link and WugFresh for his toolkit solution. Enjoy.

Hey,
I basically seem to have the same problem as you do.
My laptop also only has USB 3.0 ports and Windows 8.1 Pro 64-bit installed.
The Nexus 5 doesn't get installed, in MTP mode it is just shown with the yellow exclamation mark in Device Manager. Downloading different USB drivers including Google's and trying to manually install it doesn't work at all. I specifically checked that all older similar drivers are gone, so I doubt that older Android devices could be interfering.
On the other hand, as you noted, using an older computer with USB 2.0 works perfectly, I had the same result.
To be honest, I'm not much of a developer or Android tinkerer, so I'm not really making any progreess... In the end, I think I will follow your example and test it with a USB 2.0 adapter.
Did you manage to get it to work without this workaround?
Kind regards! :fingers-crossed:

I'm using Linux Mint. Just plug the Nexus in. It shows up as a folder. No hassle

I had a lot of issues with my S3 and my work computer (windows XP SP3) and it was because I had half installed some USB driver that windows tried installing.
I fixed the problem in device manager by manually uninstalling EVERY SINGLE USB DEVICE attached to the computer while I had my phone plugged in.
Word of caution: You'll probably uninstall your mouse/keyboard doing this.
Once everything was uninstalled I reinstalled the Samsung drivers and it worked fine.
The same computer only required me to install the Google drivers for my N5. If I enable USB debugging, I all of a sudden can't install MTP drivers, but USB debugging disabled works fine.

USB & MTP mode
I have the same problem with my Nexus 5. The only workaround to transfer files to my phone from a computer via USB cable is to enable USB debuging, set the phone to PTP mode instead of MTP and then it shows in My Computer as a camera. I can only access the DCIM and Pictures folders but for now I have to settle for this...I copy all the files I need to let's say Pictures and then using a file explorer (on the phone) I cut and paste them to the folders I wish...e.g. movies to Movies, music to Music and so on...

I had same problem. Developer Mode...USB Debugging ON worked.

I have this problem too, but I got it to work using a galaxy s3 cable. for some reasons the cable that came with N5 did not work.

Its usually just missing drivers.. You can get them straight from Google or a toolkit as mentioned! (P.s you need to download a little applet like thing from Google if you want to hook up your Mac to your n5)
See andoid.com/filetransfer for the drivers.

This worked for me when all else failed: http://forum.xda-developers.com/showpost.php?p=35854664&postcount=7
Hope that helps!

The problem I am having now connecting is that my phone got wet recently. I dried it immediately and used dessicant to withrow the water and now it works (sort of). Now when I plug my phone into my pc, the usb debugging icon doesn't even show up.
I tried connecting to both my work pc and home laptop and they both say the same thing, that the usb device has malfunstioned and that windows doesn't recognize it.
Is it time for a new phone?

Sounds like the usb is shorting. How long did you let it dry. Give it more time and try it again.

Yeah maybe thats what happened. It's been drying now for about a week. The screen was the major problem at first but has since dried there mostly.
Hopefully it will come back. Would suck to have to buy a new phone because of that.

MTP connecting problem solved
Going back to the subject of the thread: I am pretty sure that ADB drivers and SDK (I am confident that a lot of nexus users have their devices rooted and that means they must have the above installed) is what is causing some sort of conflict when trying to connect the Nexus 5 as MTP. After I reinstalled the windows (W8) on my computer and connected my Nexus 5 it took @1-2 minutes to auto install the drivers and then worked fine...I have no ideea what happens if I install ADB and SDK again...

If you tell the SDK not to install the drivers it'll be fine

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!

Hello !!!
I faced the same problem with mine...
Couldn't connect my phone with my laptop.
It installs the driver but not displaying the folder in my computer.
I uninstalled the Existing samsung driver in control panel.
Then the issue has been solved,
Or uninstall previous mobile's drivers
Try this!?!

Search for Universal Driver here in XDA. Had the same problem most of you are having. First try and BAM! Works like a champ...
NEXUS 5

Problem solved for me
I have no more issues what-so-ever after I unninstalled ADB & SKD drivers...Windows(8) installed my phone by itself after a restart and it works as it should in MTP mode and PTP mode.

[Issue] Please help, Nexus 5 not showing up at all in windows.

By this I mean, that it does not show up AT ALL, not even as a generic device with a yellow exclamation mark (which usually happens when there is a driver issue). I can't installed the driver obviously because device manager has no entry that matches my device. I tried all kinds of cables, and my friends Nexus 5, which works fine with the cable I am using with mine, somehow mine will *NOT* get detected by my computer at all. PLEASE HELP, I am unable to upload anything to it because of this issue.

You could just google lg nexus 5 drivers and find them and install or try Koush universal drivers, same just google. Hope this helps

Have you tried rebooting your phone and computer? Tried a different USB port?
ADB and fastboot have different device IDs, is the phone recognized when it's in fastboot mode (the bootloader)?

Settings > Storage > Hit the 3 dots icon > USB computer connection > MTP is checked?
Check also the Android debugging into Developer options.

I had the same problem some time ago, have you checked Device Manager>View>"Hidden Devices"? I'm not sure about the english name of "Hidden Devices", but you will figure it out.

If you read any of the instructions for installing drivers, it asks you to go to the device manager and find the entry corresponding to your device so you can assign it the correct driver. However the device manager table does not change *at all* when I plug my phone.

It's not recognised at all in any mode, the device manager table does not change at all regardles of anything I do. In bootloader mode however, i get the "ping" noise that usually happens when a device is recognised as plugged in by windows, but nothing happens after that, I don't even have an entry in the device manager to correspond with it, all i get is "generic USB hub" entries.

Yea, tried that, still a no go.

I think possibly there could be a damaged USB pin. If other nexus 5 devices connect ok

It could be the wire
Hi,
Have you tried a different USB cable? I had the power still work and the data fail on a wire that my nexus 7 came with. A standard USB cable has 4 wires. 2 power wires ( 5v DC + and - ) and 2 data wires. Some USB cables are power only and they are missing the data wire pair so make sure your using a wire that supports data connections.

I think you're on the right track, only he has tried other cables and another Nexus 5 with success, so I think it's the same issue, but in the phone's USB socket.
It isn't software on the phone as he tried bootloader too. It *could* still be driver related, but unlikely I think. I suppose we need to try another computer

usb otg

Sorry about that I must have been reading too fast.
One way to test the pins would be to use a USB-OTG with a flash drive or one of those cool flash drives that have a male micro-usb connection.

Sometimes its best to go for Wug's Root Toolkit v1.8.4 because it is very good at walking thru many driver options and such that cause problems.

Do you have any emulator software on your machine? I had similar issue when i was using Bluestacks - android emulator on Windows.

[Q] Windows 8 Not Recognizing Phone when in "MTP" mode

I am running the June 19 build of a CyanogenMod based on version 11-20140620-Sultan-skyrocket (Android 4.4.4).
I was working to reorganize my music library and finally dump iTunes. I am experimenting with a new Music Player that requires a USB synch using MTP.
The main reason for the switch from iTunes is that a lot of my Music is Lossless encoded and it just takes up too much room on my phone. I could not find an iTunes synching solution that would transcode those large files to a smaller format during the synch process (unless I go with an iPod / iPhone).
When I switch my phone to MTP mode, the PC (Windows 8.1) does not recognize it. If I switch to Mass Storage (UMS) the phone shows up in the file explorer.
Any suggestions on how to get the MTP working would be appreciated.
Thanks

Go to device manager and look for the the icon with an exclamation mark, with your phone hooked up to usb. Right click on it and update software. Then go to where it says let me pick from a list..... Choose android composite adb interface. It'll ask you if your sure, just say yes.

Sorry for the slow reply and Thanks for the post. Unfortunately Windows would not let me update the driver in error in the Device Manager. It said it was an unrecognized USB Device and would not browse for additional drivers. I tried every way I could think of to "force" it.
Just to help determine what might be going on, I restored the ATT / Samsung ICS using CWM. Unfortunately I am having similar issues with that. Sometimes the USB connects and sometimes it is unrecognized. I tested the cables and my Windows 8.1 PC with my Galaxy 5 (stock ATT KITKAT) and everything seems to work fine. I guess the micro USB port on my phone must be going bad.
Thanks again
