hi,
I am an advance user and recently brought the Samsung Omnia W i8350 a.k.a Samsung Focus Flash. Initially it connected fine and updated twice with zune since the initial stock version.
I did not had time to explore much and I am pretty new to the Windows Phone 7 environment. few days back when I connected the phone to the PC, the device was recognized as GT-I8350 and windows kept on searching for drivers but no drivers were located. I tried installing the zune drivers but even they do not allow me to connect the device to zune (hence no music, no updates, no backups )
Then I downloaded drivers from tsar3000 and they automatically instal 3 devices off my phone, one was a com port, one was modem , and so on...
STILL NO CONNECTION TO ZUNE.
I have tried almost everything but to no avail. can you guys help me?...
Regards
PS: between the last successful connect and unsuccessful connect, there was a time when Win7 stopped booting, so I simply stopped many services and booted again because I had a presentation and no time for a fresh install, could this possibly be a service issue?... I tried starting some services but the did not work. Can anyone enumerate the services required by winP7.5?... also if a manual driver is available, it will be appreciated.
PPS: I also tried running the windows phone 7 drivers from zune folder, it gives an error the device cannot start.
You put the phone in tethering mode, it sounds like. The COM port and modem drivers indicate that the phone is sending a different USB device ID than normal. On the gen1 Samsung phones (and quite possibly on the gen2 ones, but I havne't checked) you could put the phone's USB port in a mode where it would act as a modem for the PC. It sounds like that's what you've done.
Try a search on "WP7 Samsung tethering" or similar and see if you can put the phone back in its normal mode.

hey thanks,
I was just reminded, that I was one day testing the steps mentioned on this thread, to use the phone as USB modem, hence had left it there since then, Never used it though.
Great! Solved!
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.
Thanks. :good:
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.
Hi,
I'm trying to learn about serial communication with devices from an Android tablet via USB host mode. I have a tablet, I have the devices, I have the apps... they just won't talk. It's most likely something to do with the firmware on my odd tablet, or maybe I'm just missing something stupid.
The tablet:
SUPERPAD FLYTOUCH
10.2" >24GB< ANDROID 4.0 TABLET A10 1.5Ghz CPU | 1GB RAM
"About this Tablet" says:
Model: BC1003
Android 4.04
Baseband ver 1.5rc4
Kernel 3.0.8 [email protected] #2 Mon Aug 6 15:23:31 CST 2012
There are 2 USB-A ports on this device. One has a physical switch that goes from device to host mode, comes with a male-male cable for attaching to a PC. The other port is host only. I can connect a USB thumb drive and it mounts just fine, shows up in the file manager, no problems. Same for a USB keyboard. It powers any USB device I've plugged into it.
The problem:
It works well enough for most things. But, I've now run into two applications that won't use the host USB port on the thing. Both seem to want to do basic serial communication. At this point, those 2 apps are about the only things I actually want to do with it, so I'm willing to experiment.
I have a USB oscilloscope that comes with an Android app. The app installs and runs fine, but it won't recognize the hardware usb device I've plugged in. Annoying, but I don't really need it. I've recently purchased some digital scales(DROs) for my lathe/mill. There's an Android app that interfaces these scales to an Arduino device via USB. Installs fine, won't connect to the Arduino. Okay, now this is starting to get annoying. Also, for what it's worth, the Android app for doing general Arduino stuff didn't work either.
So, the USB hardware works enough to connect a USB thumb drive or keyboard but the firmware won't use said hardware to do what I want.
The questions:
Am I doing something wrong? Is there an app I can install that enables serial communication over USB host mode? Am I missing something stupid?
Is there any other firmware I can run that will allow this communication? I think I've got the Windows utility that will allow me to flash the rom. I've watched the youtube vids on dis-assembly so I can pull the internal tf/sdcard and make a full dd backup. I'm assuming it contains the roms and everything else. Actually, I'm thinking about just pulling said card and replacing it with a smaller one for experimenting. Will I still be able to flash it using the windows LiveSuite utility even with a blank card inserted?
At this point, I'm willing to play. I mean, it's still useful enough to be careful, but I'm willing to take some chances and put a little work into it. If I can get it running with the DRO software while talking over USB to the Arduino, I'd sacrifice everything else. GPS, battery life, wifi, screen rotation, sound, whatever. I'd just bolt the thing next to the mill and that's that. Failing that, I'll put it back to stock and stick it on the fridge for my wife to look up recipes, Yeah, poor tablet... motor oil and metal swarf or cooking oil and flour. No happy retirement for this tablet, sitting in a drawer gathering dust.
Any hints, links, recommendations, or directions appreciated.

I installed "L" on my Nexus 5 when the image was first released, and I've left it on since. The bugs were a minor annoyance to me, and I enjoyed having the latest OS version. Now that the release of "L" is growing closer, I've decided to switch back to stock so that I'll be able to OTA update once it's official. However, I can no longer connect to my computer via USB. The computer will recognize that there is a device attached, but then return Unknown Device. I was able to flash "L" to the phone, and had previous flashed Cyanogen, so obviously it used to connect.
I've done some searching and seen other people with the same problem, so just to cover all of the basic questions, I have done all of the following:
- Rebooting both devices.
- Switching USB cables (7 different cables).
- Tried every USB port on 3 different computers.
- Tried connecting a Nexus 4 and Nexus 7 to ensure the USB ports and cables worked (they worked).
- Switching from PTP "camera" to MTP "media" under USB settings on the phone. Also dev mode.
- Installed the Google USB Drivers.
- Reinstalled the USB drivers for my computer.
- Uninstalled all drivers, rebooted computer and phone, reinstalled drivers.
- And probably some other things I'm forgetting right now.
Questions for anyone who can answer:
1. Other threads have suggested to other people that the USB port on the phone may be hooped. If this is the case, is there any option of sending it back to Google to be replaced/repaired? It was purchased less than a year ago through the Google Play Store.
2. Is there ANY other way to revert to stock Android without plugging in to a computer? I'm worried that I'll be stuck with this dev preview of "L" forever, and that's just unacceptable (not throwing blame, I know it's an at-your-own-risk preview, but I don't want to buy a new phone right now).
Thanks for any help.
Will it recognize itself in ADB or Fastboot mode(Through BL)?
Any commands returns "Error: Device not found."
adb devices returns nothing.
edit: Fastboot DOES recognize it through the bootloader! I hadn't tried that! Frantic tinkering will now ensue, thank you!
Hi,
I realize that there might be an answer to this already, however I have been searching for a while and no such answer has presented itself. I have come across other threads on this forum that explain how to get in. However my concern is that these are really old posts and perhaps point to an older version of Android?!? The reason I didn't follow those tutorials is I am afraid of wiping off any data that might exist on the phone (which is not something I would like to do!!!)
So it is as follows:
LG NEXUS 4 - 02 NETWORK UK
NOT ROOTED
STOCK EVERYTHING
USB DEBUGGING DISABLED
CRACKED SCREEN\DIGITZER - NO TOUCH RESPONSES ACCEPTED
So my question is this, can I access the files on here including all music/photos/contacts/messages etc and back up to a WINDOWS PC. Please forgive me if my responses sound noobish to you, as I am not familiar with Android, so might ask some daft questions.
Thanks in Advance
Anybody? I fear for trying anything as I do not wish to loose pictures etc.
Stock Everything
Not Rooted
No USB Debugging Enabled
Can I enable usb debugging through adb?
you do not need usb debugging enabled to transfer data from device to pc, my question is, when you plug your device into your pc, does your computer recognize it as a mass storage device and can you see your phone in the list of devices with removable storage ?
