Cant connect "disk drive" style to PC??? - Verizon Galaxy Note 3 Q&A, Help & Troubleshooting

I have not had any luck locating other people with this issue.
First off let it be noted my note 3 will be replaced tomorrow by a new note 3 (severe signal issues hampering the ability to make or receive any phone calls)
That being said, I was trying to back up some app data and long story short - I'm trying to connect my phone to the pc but the PC refuses to acknowledge it.
When the phone is plugged into the pc (usb 2 - any port) it simply charges the phone and calls it a day. No popups - no notifications - no verizon bloat spam.
I've tried installing samsung drivers via download, I've tried their Kies software. I'm getting nowhere.
Also - an odd thing - I was trying to get Helium (carbon) to work and it had me enable USB Debugging (pretty standard procedure) - When it asked to do that it auto popped up the setting page which was labeled something like "developer settings" (helium actually opened up the setting page for me) and I did - Prior to that and since that point I cannot find that settings page anywhere on the phone, as thats the page I was looking for the "disk mount" option that I'm used to seeing on my tbolt. Helium wont bring it up again either as usb debugging is enabled now.
what in the heck is going on with my gn3???

You can get the Developer Options screen in the settings by going to About Phone and tapping on the Build Number line repeatedly until it says "You are now a developer."
As far as mounting as a disk, that functionality is long gone since the Thunderbolt. There may be a yet unfound way to mount just the external sd card as a drive, but the internal memory is formatted with ext3 or ext4 and windows wouldnt touch it if it could.
Im not sure of your computer setup, but if you are using an OS before Windows 7 you may need to install the MTP porting kit from Microsoft (http://www.microsoft.com/en-us/download/details.aspx?id=19153). All newer Android phones now use the highly inefficient, annoying MTP protocol to do file transfers through USB.

Just learning about this myself because just changed from note 2 to note 3 and had no problem on note 2. Seems like wifi transfer is a fairly easy way to go. Download something like WiFi File Transfer then you can search hidden folders and such and transfer files. Not as easy as mounting the drive though. Would like to know about other options.

Activesync 4.5 Problem: won't connect to my device anymore

so i thought i'd give vista's "windows mobile device center" a try on my vista laptop, and wasn't surprised to find that i couldn't get it to recognize my phone. i was surprised to find that the xp computer that i've been using with activesync for a long time suddenly stopped recognizing my phone as well.
up to now i've hard reset phone (dcd 3.04, 3.37 radio) and reinstalled activesync 4.5. no dice. please if anyone can help me troubleshoot this thing i'd be way grateful. why has my phone stopped communicating with my computers?
For WM 6 devices, on Vista you must upgrade to Windows Mobile Device Center 6.1.
i downloaded and used 6.1 on my vista machine, but it didn't work. any other ideas? i think there may be something that changed on the phone, because now, activesync won't work either...
...bytheway, the phone will charge when plugged into either, but that's about it.

Just for ****s and giggles, have you tried the following:
1. Using a different usb port
2. Blowing the dust out of the port on the phone
3. Using the Y adapter that came with the phone in between the sync cable and the phone
First, plug into the USB, wait for the Windows new device chime, see if anything occurs in the WM Activesync.. If no Activesync connection is made (after the 'connecting' has stopped) then unplug and plug in back in another USB port. Do that at least 4 times (cycling between ports...even the same may eventually work) to see if you have a success.
Restart your PC, Soft-rest your phone and try again.
If still nothing, then don't bother plugging your phone in and then Run As An Administrator the attached batch file and then under View 'Show Hidden Devices.' You'll now see all devices that have ever been installed and retained for your OS, with the faded devices as those not currently attached/active.
Rather than the batch file you can open up a Command Promp Window with Administrator access (Start\Programs\Accessories\Right Click on Command Prompt and Run As An Administrator)
(I usually keep that batch file accessible in the root of my OS partition, just to keep it easy to clean out legacy device drivers that can cause problems.[/i])
Enter:
set devmgr_show_nonpresent_devices=1
start devmgmt.msc
Uninstall
Network adapters\Microsoft Windows Remote Adapter
Portable Devices\PocketPC
Then under Programs & Settings uninstall the Windows Mobile Device Center upgrade, and then reboot your PC. Reinstal that Device Center 6.1 update and then again connect your phone with the USB. (for the XP machine you can do all of the and unistall/reboot/reinstall the ActiveSync 4.5.
(note to self or another.....these steps to be added to the Wiki for ActiveSyn issues)
well, i'm thinking that the "****s and giggles" have it. i blew into the port, plugged her in, and it connected to my xp machine, just like days of old. after about 3 minutes though, the connection dropped, and i've not been able to get it going again since. i think this rules out any software/settings problem, and looks like it's a hardware issue. i'll try cleaning it one more time a little later, and if no go, i'll have to figure a way to re-flash the stock rom (i only have a 6gb card...) and send the beast back. thanx for the input, guys (specially keystone, dang man that was one badass post with some instructions that will help someone, i'm sure.)
Do you have the Y adapter that came with the phone? The one with the audio jack and the 5 pin mini usb on one end and the 11 pin mini usb on the other? The reason I ask is because for some reason HTC decided to put an 11 pin mini usb connector on our phones, yet supply us with a data cable that's standard 5 pin mini usb. If you have it, just humor me and try it and see if it keeps the connection.
Oh and P.S....the "****s and giggles" wasn't just a shot in the dark. I've solved many activesync problems for people before using all 3.
I actually hadn't used the cord without the Y-adapter untill today. both ways yeild the same result.
Another Activesync problem
I've been on vacation the last week and while away i had to do a clear storage..anyway, my phone was fine but when i connect thru activesync i get an error code : 85010014 and my contacts list doesnt get updated...:S can anyone out there give me some advice or do i hafto start from scratch?
Also is there a way to find my contacts on my comp?

Well the hoop jumping is fun and all but I think if you uncheck the "Enabe advanced network functionality" in Start > Settings > Connection > USB to PC it may help.
Damn! That was simple. I unchecked the "Enabe advanced network functionality" box and I'm up and running! I'll save the hoops for later. Thanks!

Hi, thanks that work for me fine too
my mogul has been giving me crap with vista and xp for weeks. Nothing can solve it. I've re-flashed, downgraded, used different ports, different cables, modified the USB to PC settings.
Add this to the list of things that randomly seem to be a problem for this phone.
I had a similar situation, none of the software based suggestions fixed it. Wiggling the cord around would sometimes connect, but soon thereafter, my phone stopped charging. The USB port was the culprit, so be careful.
I'm sure everyone who was having troubles figured out solutions, just thought I'd add in my dealings with this.
I just had the phone activated today (yes I bought used) and brought it to work to sync with my work outlook, well the usb cord would charge the phone but give me nothing but errors in the way of actual data connection. I was a little bummed this afternoon thinking I bought a partially broken phone. But WHILE HAVING THE PHONE CONNECTED ( I bold because I had done this multiple times while not connected and had no results) I opened the Comm Manager and clicked on the sync button at the bottom, suddenly my computer could recognize my device and I was sync'ing like a mad man.
Very possibly a stupid thing I should have done from the start, but I don't know any better since I'm brand new to all of this. I only post in hopes of helping another bummed out soul as was myself
I an running a HTC TyTN-II 4550 phone (WinMo 6.1) on a desktop PC (WinXP).
I couldn't get Activesync 4.5 to work either, but there were obvious reasons--my version of Office 2000 isn't supported (2003 is the earliest, I think) and IE and Outlook are not set as my default mail clients (-and that's how I like it-).
I didn't really need Activesync but I did want to be able to get files on and off the phone from my desktop PC through the USB cable. When I'd connect the phone, Activesync would automatically start up and spin the little logo for a while and then say "connection couldn't be made" and then I couldn't do anything--even move files on and off the phone.
What I found works is this:
1) open the Task Manager, and kill the wcescomm.exe process.
2) navigate to the folder that Activesync is installed in, and run the file named WCESMgr.exe.
3) that will popup a window, asking if you want to sync, or cancel. Press [cancel]
4) the normal Activesync window will come up, and the choices for "Sync" and "Schedule" will be greyed out, but the "Explore" button should work.
Sometimes I can disconnect and reconnect the phone without going through steps #1-#4, but not always.
With the "Explore" window you can drag files on and off the device.
I tried dragging small Word and Excel docs on and off; both converted properly when dragged onto the phone, but only the Word file would convert again when dragged off.
The phone will access the internet through the USB when hooked up this way, also.

My HD2 freezes/crashes after connecting to USB in my PC

After installing Miri's rom 6.5.x my HD2 started crashing every time I connect it to the PC whether it is on ActiveSync or DiskDrive mode. It sometimes crashes right after I connect it , but most times after I disconnect it. I have installed Steve007 and SUperboy007 Elegance theme , Midomi , ManilaBirthday , Klaxon , NetRipper's KeypadLedControl , CorePlayer 1.3.6, AppToDate, JWMD Icon Changer, TouchPal, cleanRAM, TorchButton, Chainfire HD2 3D Driver Patch, Mosko.Mobi FIM , Jaguaralani HD2 Action Screen , SRS WOWHD , Resco Explorer and Resco Photo Manager , Xtask , SPB Backup and BSB Tweaks 1.6.
Could you please tell me what is wrong ?
I did hard reset after I flashed the rom.
Anybody?
your whole device or just audio manager?
dont know if this is of interest to you:

My problem is different.My whole device crashes and needs a soft reset after I disconnect it from the PC
Have you installed any of those to the storage card? Because the storage card is not available to the phone when you connect in file mode, though it should be ok in active sync mode. Most of those things should not be installed on storage card anyway.
Also, when you connect the phone it seems to me that it starts to prepare the pre-selected option right away, so if the last time you connected in file mode, this connection will be opened as soon as you connect, and if you change to another connection, the first connection is dropped and the other opened. To avoid this you could go into the usb settings and change connection mode before inserting the usb cable.

I've found my HD2 the same problem. As most of my apps were installed on SD card, when I connect the phone to PC, it's OK until I run an app that was installed on card while the phone remains connected to PC. Afterward, the phone freezes without any word.
Just a piece of my own experience...
Are there any new hints on this item?
My HD2 also freezes, as soon as I disconnect from USB, using hard disk mode. (When using USB to ActiveSync, there are no freezes).
this used to happen to me 2 months ago, but i cant rememeber what was eactly the reason, it may have been 'a theme, task manager or as i rememeber i suspected G profile '...
nothing of these is installed on my device (beside the OEM task manager).
Thanks anyway!
Just try to give it some time. Due to the fact that windows as well as several programs use some kinda autoplay options when external storage device are connected it may take some time until you can use your device. Mine freezes for seconds to one or two minutes until it can be used.
I remember when I made a rom and it didn't include a few oems in my kitchen, it caused freezing when I tried to access the sd card when connected to the computer
have you flashed a new rom to see if the rom isn't the problem?
I only flashed the new official Vodafone 1.72 ROM.
Exactly same kind of problem in HTC touch HD
I know I am discussing this in HTC touch HD2 forum, but I have HTC Touch HD and facing exactly same kind of problem. Have Upgraded from 6.1 to 6.5. Worked flawlessly for 5 months until now. Phone freezes in the Today screen right after connecting to computer thru USB and have to resurrect by resetting. I have Winterface UI installed. It used to work fine before. Please help.
I have noticed after many many efforts and after reading many subjects about the freezing issue, and after almost dumping the HD2 in the garbage, that the reason for this problem is the SD card 32 fat. I have switched a couple of 8GB cards and the system freeze starts within minutes. Then I copied every thing onto a 4G card 16fat and the mobile is flying since then.
Also avoid spb-traveler as it has a conflict with the device making it very slow and full of errors.
Still a problem...
I was excited when I saw that someone had posted on this subject, as I too am plagued by my phone crashing when its connected to USB to the pc. Unfortunately, the post was from a long time ago. I'm using the newest T-mobile rom 3.14.531.1 and it occurs EVERY time I plug the phone into my Windows 7 computer or my Mac...
I don't specifically believe that it's related to the SD card itself, because I can connect in Android via USB and this isn't a problem. I suppose, this could be an issue if it's just related to WM 6.5. My next option (my phone is not with me currently) is to remove the SD card and plug in the phone and see if the same thing happens. If it still occurs, I believe that would 100% rule out the SD card as the issue.

Well, I removed the SD card and when I plugged it into a computer it STILL acted weird. The symptoms seemed different though. First, I can't hit the start button. Well, I can physically touch it, but it does not respond at all. Nor does the start icon at the top take me to the start menu. Also, I tried to go into settings > Menu > All Settings to then turn off sense to see if that was the problem, and it won't even let me in to the 'all settings.'
I guess next step is to just do a hard reset in hopes that this fixes the problem, that or move to a custom rom. I just don't really want to do either because I have a lot of stuff I'd rather not tweak to get to where my phone is at again.
If anyone has any ideas, please help.
Thanks
Hey
Just turn the data sync options like fb and twitter to off. ANd you phone will be running in no time. JUST went to the same problem today and found turning data options off as the best solution.

Can not access from PC both SD or Internal flash storage

Initially all worked OK. But then after some installs from the Market i am not able to do that
Here are some facts:
- i see the drive letters assigned for both of them on PC but when you click Explore the message is "Please insert a disk into drive M: (or N or whatever)".
- They are shown as mounted on the phone . Dismount and mount again changes nothing
- the phone is recording photos/videos OK on internal memory means flash is working fine.
- SD card is perfectly working too. if you extract it and put into computer you can read/write it. On the cell you can play music from it etc no problems
- I restored everything with Factory Data Reset but things did not change
- Same story from another PC
Is this some driver problem ? Or flash memory is locked by Vibrant OS?
I suspect EasyTether or PDANet third party driver for Samsung phones is responsible.
Tethering works though
It's probably one of your 3rd party apps. Mine works fine.
Isn't it strange that combination of cell factory reset + another fresh PC does not work?
S4X, I had the same issue this morning. I was performing a data transfer and had a error message (from computer). From that point forward my phone was no longer able to mount the internal storage, external micro sd card. The only portion of space that was recognized was the dedicated internal app space. Wiping the phone failed to repair the issue. I took it my local tmobile store and they immediately swapped it for a new one. No hassle no fuss. I hope these are isolated incidents. So far my new new phone is working great.
I'd recommend a return.
I should note, my phone was not rooted and I did not have either PDAnet or Easytether installed.
Same problem here, have not fixed problem yet. looks like it's getting replaced tomorrow.

Sorry to hear about your troubles, I'm keeping an eye on it. If it happens again I'll post something. In the meantime, I'm avoiding any multi-gig file transfers. I'm hoping we're just two unlucky owners and this is not a wider issue. Otherwise, I love the phone.
try turning on development mode. With that off, my mac wont see my vibrant at all. turn it on, and everything shows up.
i think easytether caused the issue
i couldn't get pdanet to work, they didn't have the correct samsung driver, so i unistalled pdanet from my laptop
installed easy tether yesterday - had a heck of time getting the driver to install
then tonite, like you said, couldn't get the laptop to recognize the phone,
uninstalled easytether, re-installed, and actually did it a few times tonite - took about an hour to get my laptop connection working
the hardware recognized changed from Samsung T959, to CDX morem something, and finally when on the last attempt it was recognized as an "android ADB device" and i let windows auto install the driver, it's now working
really think it's easytether and that driver not being stable
i'm on a windows xp w/sp2
Thanks for responds guys but happily after billions of different attempts the problem is solved.
I still can not understand how these changes to the phone happened. Probably some installed software changed in Vibrant something.
Anyway, here it is, it's very simple, but this has an additional step to what it was before nevertheless. After usual USB cable connection and confirmation of using the phone as a mass storage device on the phone popped up menu (if you've made this selection on the phone settings), say into Voice dialer: "Open SD Card", and when new screen appears, click "Enable USB mass storage"
I can also post the way i tether if you like. It works fine like it works fine with EVO for example. T959 is recognized well
As you know compared to EVO and other phones the Vibrant/Samsung Galaxy S only requires one more step before installation of application on your PC: it needs Samsung own USB driver.
So you get from Market and install application on your cell; download driver from the web and install on PC; download and install application on PC.
---------------------------------------------------------------------------------------------
Here are some details for those who never tried tether and might need step-by-step instructions:
Step 1) Get and install PdaNet or EasyTether from Market on your cell phone and in Settings/Applications/Development check ON "USB debugging"
Step 2) Download and install USB driver for Samsung cellphones on your PC. Same driver works for both PdaNet or EasyTether applications. I took it from (i am new user at XDA and am not allowed to post the links) www (dot) mobile-stream (dot) com/easytether/android (dot) html
Step 3) Google, download and install PdaNet or EasyTether ( i usePdaNet, it has Bluetooth data connection option also) on your PC. During installation the application will find that the driver is already installed and will ask you what to do, you answer NO to reinstall
When you will need Internet connection:
a) Connect Vibrant and PC using USB cable
b) Launch PdaNet on Vibrant, push button "Connect"
c) if you set up not automatically connect then click on PdaNet icon "Connect" on your PC (in the task tray in right bottom corner)
Done !
Novices also may not know that these applications are free for 1 month for both secure and regular unsecure http/https connections. Then if you need https you have to pay one time fee ($10 or $18) which will work on one phone and several PC. Just a regular http stays free.

Plug in hd2 it charges but wont read sd

I plug in my phone to my computer and ut charges but it wont connect to computer through DISK DRIVE WTF... I RESET IT TWICE AND NOTHING... ITS NOT CORD OR PHONE CUZ IT CHARGES...
when you plug it in to your PC in a mass storage mode the memory card is locked
the phone acts as a thumbdrive so you can drag and drop files onto your sd card.
theres a prompt that AKSs?(asks) you what mode would you like to connect.
either sync or mass storage.
every phone does it same btw.
Two possibilities-
1. Your card may have gotten corrupted. It's a fairly common occurrence and it will cause your phone to not be able to read it. Plug it into the PC via a card reader & see if you can see any files on it. If it takes an unusually long time for your comp to see it, or if all you see are wierd files with numbers as names, then its corrupted. Even if it loads fine, it wouldn't hurt to reformat it anyway just for the sake of maintenance. I suggest formatting it as fat32 with 64k allocation unit size for the best read speed.
2. Your settings on the phone are incorrect. Go to settings>system>connections>USB to PC and make sure the disk drive option is enabled, and that the "ask me first about USB connection type" option is checked.
If neither of those fixes it, back up your data & try a hard reset. If that STILL doesn't fix it, then your card is dead.

USB MTP/PTP Connection Problems to any computer.

Hello, I've had the V20 for a number of months now and love the phone, but I never tested out a data connection before, only to find out that when I use both the LG cable and a Anker USB3.0 cable, my phone is not able to connect to any computer. The system prompt to select the MTP or PTP connection appears, but after making a selection and the computer seeing the phone for a split second, the connection is lost and the USB prompt appears rapidly over and over again. I even went into developer options and set MTP connection always.
I tried a reboot, battery pull and capacitor discharge, and a full system restore. No fix. The only work around I have now is a samba server or moving files with the SD card manually.
Please, if you have any ideas? Does not work in Windows and Linux.
Thank you.
Have you installed LG bridge?

Did you enable USB debugging in Developer options? If no, enable it.
Change the power settings in windows for the USB.
Power options
Advanced settings
Disable "USB selective suspend setting"
Tried all the above

Yes, USB debugging works and I'm able to use ADB with my phone and both the Windows laptop and Linux Desktop. However, neither is able to reliably connect through the typical MTP and PTP methods. I finally got MTP to limitedly work with MTP when I use the LG supplied cable and ignore the USB connection prompt in Windows and Linux. I go straight to File Explorer and access the file directory of the phone. Every time I open a folder or access a file though, the phone rapidly pops up the USB connection message over and over while the file moves.
All third party cables and USB devices are not working other than just charging. In Linux, the error message in my logs is:
usbfs: process 20678 (mtp.so) did not claim interface 0 before use
reset high-speed USB device number 101 using xhci_hcd

Is this behaviour on accessing and copying? You can not copy a file from your Windows laptop to the phone?
Yes, I cannot open folder directories, nor move files from phone to computer or visa versa.
Also. Try to not let the phone screen turn off. Change display time to 15 minutes or something.. Change back when finished. GL

I was able to transfer files both ways via USB and had the pull down USB options without ever having to add USB debugging. Then I installed AVAST and USB has become charge only... none of the widely recommended solutions above will unlock USB. I see no apparent settings in AVAST so I will call them. If no resolution then I will trash Avast

No, I never could resolve it. I ended up using Samba to fileshare with home computer, but lost any OTG cable ability. Never used antivirus or security software with my phone.

Just fixed it... turned out to be the port on my PC, I switched ports and its back as it was, no need to enable dev mode or USB debug... its still slow connection... I have to look up Samba solution, never used it.
Thanks for sharing
I just experienced the same problem with the USB connection constantly cycling between being plugged in and not. Windows kept alternating between the device connected and disconnected system sounds. I unplugged the USB 3.0 to USB-C cable on both ends, unkinked and straightened it, and plugged the cable back into the PC and the phone. Hasn't made another peep for the last half hour and the phone is staying in USB file transfer mode. I wiggled the cable at the phone end and still no further disconnections. Maybe I didn't connect the cable securely at the PC end the first time.
This is the first time this has happened since I started setting up the phone this week, so I don't know what to make of it. Regardless, I need to order some more USB-A to USB-C cables since this is my only one.
USB File Transfer Issue - Resolved
Hi, I had the exact same issue with the computer not seeing the phone as far as files. I was still able to use ADB, Fastboot, etc, so I figure it was not a hardware problem. Tried two different computers as well. Every time I selected "File Transfer" in the USB settings, the phone would beep, and when connected to the computer, the computer made the usual chime. The phone would not show up in explorer still.
Previously this phone had been rooted, but I wanted to bring it back to stock. I had flashed the latest KDZ file. Then using ADB and Fastboot locked the bootloader. It seems that the USB issue happened after that. Here is what finally fixed it:
Turned on developer options the usual way (tapping build number in software info) and then turned off "Allow OEM Unlock." Then I turned off developer options. Still, no luck, so I then re-flashed the latest KDZ (H91820h) again, but this time with the bootloader locked.
After everything was done, I set the phone up again, and now file transfer works perfectly.
I did not want to chance locking the bootloader while the phone was still rooted. I learned the hard way about that, and nearly bricked the phone once before. Luckily I still had factory upload saved in the LAF partition.
Hope this helps someone out there.
Turns out it was not fixed permanently

After thinking it was in fact fixed, I rebooted the phone several times, turned off, then on, and all seemed well. Until the next morning. I turned it on, and the same issue happened again. No File Transfer mode to computer. ADB still worked. After being on for a while and getting warm, all of a sudden file transfer started working again. Rebooted, and turned on and off, and it continued to work. I figure its a bad part with a thermal issue somewhere so I put it in the freezer for 5 minutes. When booted up again, the same problem occurred until the phone warmed up. Weird? So I tried something completely different. I downgraded the phone to H91810p and tested again. It seemed to work fine. I put it in the freezer again, and the problem will not show itself. For whatever strange reason the problem appears to be heat related, and ONLY happens with the latest KDZ, Oreo 8.0 The only thing that I can theorize is that the SOC is bad, or there is a bad area of flash memory that is intermittent.
Does anyone have any clues? I am going to put it back in the freezer, go to work, and test again when I get home to confirm.
