Getting debugging drivers working on Windows 7

Hello
I have a stock Vodaphone Magic and I'm looking to root it, but to do this I need to get adb to see it, which I'm having problems with.
When I plugged it in first to charge it used window's default drivers for the SD card etc. Trying to update the drivers with the ones included in the SDK dosn't seem to work as Windows says that they're less recent.
Also, I can't see any sort of "ADB" section in the device manager, even with USB debugging turned on in the phone.
Any help? I'd really like to root my phone so I can use WPA Enterprise!
Edit: Already read the wiki page, no help.

I remember having this problem when I first set up the Android SDK.
However in my device manager I did have a device, it wasn't called Android or Magic or anything similar. From what I remember it was a bunch of random letters and numbers.
From there I right clicked it, went to Properties, Update Driver and then pointed it to the directory with the drivers.
Thats how I did it in Windows 7, if that doesn't work for you then I'm not sure sorry.

Hi,
I recently had the same problem as you. The first time you plug in your phone sometimes Windows will assign USB drivers to the device instead of the ADB interface. To correct this, I uninstalled the drivers and pointed the computer to the ADB files as the new drivers. After those install it should be labelled correctly and work.

Cannot transfer files with MTP / Device not viewable in Windows Explorer

When I connect my Nexus 7 to my Windows XP (SP3) PC via USB, it's obvious the computer recognizes it and it tries to install ADB drivers. Whether I choose to install those drivers or not, I still can't locate my device in the Windows Explorer Tree. I checked Disk Management for the hell of it and nothing but my PC's harddrives were there. There's an attempt to install drivers for "MTP" but that fails and I'm pretty sure that's the cause; however, I'm unable to replicate it, even as I uninstall/reinstall applicable drivers from the device manager the MTP failure never happens anymore. I did some googling and found a thread with someone who had a similiar experience. In turn, I downloaded https://www.box.com/s/2c25e8bc42ecce400afd to try a different set of drivers. Same problem. Driver install is fine for ADB, but still unable to see my device in Windows Explorer. I'm able to successfully connect the device to the PC with PTP for the camera. I can access DCIM and cache which can serve as a work around, but I'm hoping you can provide any ideas you might have. Thank you!
edit - ***resolution***: Ok, I figured it out...I had to disable USB debugging. I don't know if this helped either, but I installed these drivers as an alternative to the drivers that were originally installed: https://www.box.com/s/2c25e8bc42ecce400afd
While connected to PC, I switched to PTP mode because I was about to give up and just use that
I then disabled usb debugging and switched back to MTP at which point the drivers successfully installed and I could now view my device in Windows Explorer. I also believe downloading the drivers in the link above helped since the first crack I took at this was unsuccessful with existing drivers.

install pdanet on pc and it will install drivers for u so it will be recognized

Been battling with this on my XP machine since yesterday. I couldn't even get debugging to work until I installed NakedDriver. And even still, there seems to be no way to get MTP to work without turning debugging off. On my Win7 machine everything worked perfectly, both ADB and MTP, right out of the box. I have the Galaxy Nexus drivers installed on both machines (which I've read are compatible with the N7). I also have the latest version of Windows Media Player (I've read that some older versions have issues with MTP). Is anyone else able to run ADB and MTP on XP?
*edit*
A: Does PDAnet let you use MTP and ADB simultaneously? Because I really don't want to install it if I don't have to. I got rid of it ages ago (too many things starting up at boot time).
B: I have a Galaxy Nexus also, and I have no issues on the XP box.

I wouldn't bother with MTP, it's not always showing the contents of the internal storage properly when viewed in Windows Explorer.
Earlier today when I was trying to set up a backup profile for it, it didn't copy all the files off. On closer inspection I found folders like TitaniumBackup to be completely empty, which is not true according to ES File Explorer on the tablet.
I tried connecting MTP again, with USB Debugging on and off but this made no difference. Also I'm only seeing the Notifications folder instead of 36 folders on the internal storage now, really random how it's working.

Same here. No change with the Asus drivers. Still can't use MTP when ADB is turned on.

poo. how do I transfer my audiobooks to this stupid device without working drivers?

1. Please disconnect Nexus7
2. Remove drivers on PC.
3. Toggle ON : Settings->Wireless&Networkings->More->NFC.
4. Re-connect device
Good luck !

1. Uncheck MTP, check the one next to it (Camera)
2. Unplug USB
3. Turn off USB Debugging (Uncheck it)
4. Plug in USB
5. Should say connected as camera, then a new window will pop-up allowing you to see your files.
Tell me if it works!

im having trouble too, is there any way to make the device to be recognised as a flash drive?

Same observation here (a few months later) on stock Android 4.1.1 rooted.
It seems that new files in the internal memory remain invisible for a long time, but so far they have become visible eventually, sometimes a day or two later. I have no clue what could possibly cause this, and I have not found any trick or workaround that makes them visible, not even rebooting. Any hint is welcome.

Didn't work. Just shows up as a camera with the limited folder access one would expect.

Workaround
I now use the following workaround.
Install SDrescan from Google Play.
Run it.
If you already had your phone connected to a computer as a media device (MTP) and are watching the contents of your SD card or internal memory in Windows Explorer, press F5 to refresh your view. If not, connect it now.
I'd be curious whether this works for you as well. If it does, press the THANKS button below.

Same issue with an old ibm x40 udated to windows xp pro SP3.
I've installed mtp driver, without success
I've "tried" to install asus driver, without success
I've tried to do as above with the help of the nexus toolkit, without success.
Everytime, the laptop recognize the device as android ADB interface.
Someone could help me?
Thank you in advance

Can't Get Debugging To Work On Nexus 7

I'm trying to run my app while debugging on my Nexus 7, but it always loads in the AVDs instead of on the tablet.
Here's my checklist of things I've done:
Went into the settings on the Nexus 7 and enabled USB Debugging.
Installed the official ASUS Nexus 7 drivers. When I connect it to my PC, Windows 7 64 bit pops up and says the Nexus 7 is connected and the drivers loaded successfully.
Connected it to my PC (Windows 7 64 bit) and it pops up and saying the Nexus 7 is connected and the drivers loaded successfully.
However Eclipse doesn't detect it at all. The app loads the AVD instead of it. And if I go to Run As->Run Configurations->Target, it's not listed. If I select Launch on all Compatible Devices/AVDs and choose Active Devices and then try to run, I get the error "No active compatible AVD's or devices found. Relaunch this configuration after connecting a device or starting an AVD".
The app is set to be compatible with Android 4.1.
Suggestions?

The only way I've ever gotten it to work is switching the 7 from a media device to a camera.

Strange. Unfortunately it still doesn't work for me. Same symptoms. Thanks though! Any other ideas?

I found I had to fiddle with the drivers a bit to get the proper adb connection. Check Device Manager and make sure it shows up under Android Phone->Android ADB Interface. If you see anything else you'll need to uninstall the offending driver and reinstall.

Ehhh...Crap. You're right. Device Manager shows Other Devices -> Nexus with a caution sign on it. Weird cause when I plug it in it'll ask me if I want to transfer photos and it'll mount it as a drive and everything....grrrrrr. This might be annoying.

I'm trying to remember exactly what I did to get the right driver to install. I think you need to uninstall the all drivers being used and then make sure that USB debugging is turned on in the Nexus before plugging it back in. I used the Wugfresh toolkit which includes tools to check what drivers are lurking around in your system.

Finally got it. Turned out, the driver files were no good. I got them from a link to Asus's site from another thread. I googled their site for different driver files and found the correct ones:
http://www.asus.com/Tablet/Nexus/Nexus_7/#download
It should be a zip file with USB in the title.
Thanks for the help!

I can confirm this, I switched it from MTP to PTP and installed the driver, and everything is working now. It's showing up in the ADB list.

Download the asus drivers and extract the zip file. Plug in your Nexus 7. Go to Device Manager -> the device (might be listed as an android device) -> Update driver. Browse to the extracted folder.
On the Nexus 7, make sure USB debugging is enabled. And, when it connects, change it from being connected as a media device to instead being a camera device.

Thanks. I ended up being able to do it with the one click root program it helped me get the drivers super happy. Now my galaxy nexus and nexus 7 are rooted. Haven't had something rooted since my Samsung galaxy s fascinate

Been at this fir 3 days. Installed, uninstalled drivers. Got ASUS drivers. Switched from Debugging on to off, then off to on. used Camera, used Media....The closest I come to seeing Nexus7 in Explorer or Computer is INTERNAL STORAGE/DCIM OR CAMERA.
I am unable to see any files, no matter what I do. So, now I must ask this: Must I be rooted to see android files? I doubt it, but I never used a Nexus before. Quite frankly, this tablet is awful for use with a PC. I need help-can u help me, pls.

Can I ask for your help guys? My Nexus 7 v1 is stuck on boot loop (either stuck on google screen or sometimes would proceed up to the nexus animation screen) and I've been trying to fix it with the Nexus Root Toolkit (NRT). I just have problem proceeding with the steps since the toolkit advices me to enable my device's USB DEBUGGING (open device , go to settings, then developer options etc) which I CANNOT POSSIBLY DO COS AGAIN, NEXUS IS JUST STUCKED ON BOOT LOOP.
Can you suggest OTHER ways I can enable USB Debugging in Nexus 7? I would greatly appreciate your help.

Problems connecting via MTP

Ok so a little background. After hearing about the Carbon backup app a while ago I decided to install it and followed the instructions to do so. One of these steps is to change the normal USB drivers to the ATB ones from the Android SDK. I did this and it all went well without a hitch. However I came to add some movies on to my nexus 7 today and it would only recognize my device in PTP mode (as per the Carbon app requires). I proceeded as normal but found that I could not create a new folder for my films. When i tried i was faced with this error:
However I found that I could create a new folder in one of the existing sub-directories so I proceeded with that. I started copying the movie files over and got another pop up looking like this:
After clickking yes I was soon faced with another error screen:
This happens for nearly every video file i have tried to transfer. I have tried uninstalling the ADB drivers and letting windows install the default drivers it used the first time, however now it will not find any driver software for my nexus 7 unless I point it to the ADB drivers. Whenever I try to connect my device as an MTP device instead of PTP windows will not recognise it and nothing will show up in my computer. Is there any way that i can defer back to the default drivers and use my device on MTP instead of PTP?
Just for a bit of extra info, the same problem is occurring on my nexus 4.
Thanks

Hmm, i have adb drivhttp://forum.xda-developers.com/showthread.php?t=2214386alongside stock drivers for mtp as im sure many do n do not face this problem.
Have you uninstalled the backup app and cleaned the registry?
Try going in to device manager and enable 'show hidden devices' and search for any leftover usb drivers or interface that might interfere with the stock drivers. As a last resort you can download your usb chipset drivers, then uninstall all chipset drivers and usb devices including those hidden, then reinstall the chipset and other drivers u may need. Eg.printer drivers, then try again.
Previously i had a sony erricson phone and it's SE's software screwed up the usb interface n i wasnt able to connect anythin thru usb mtp. That helped me. Alternatively, if u have system restore on you can try restoring to a date before this all happened.
Also, check your device for any apps or settings that might interfere usb functions like usb debugging altho it's rare. Not sure what you did but you might have semi/permanently broken some settings in the device...if you had an earlier backup which was flawless, try restoring to that first. Remember to play safe when doing all troubleshooting, windows isnt exactly smart with device drivers =< worse case you have to reset both the usb drivers and device if nothing works...

i faced the same problem last week. what i do is go through step by step like what nexus root toolkit suggest. start from scratch. remove all previous drivers and reinstall. Follow to the letter what it says. So the problem is just probably of a bad driver stuff. Remember to restart too.

[Q] USB Issues with Windows 8.1

put in a new SSD and got Windows 8.1, did a fresh install on a new hard-drive, everything's been working great, My nexus 4 has worked with with ADB./Fastboot and I've been able to transfer files to and from it in MTP mode. Been like that for about 4 days until about 3 hours ago, I had Windows Explorer crash, had to run Task Manager, end the process, and then manually restart explorer.exe My device was plugged in when this happened, and afterwards, I noticed that I could no longer see my Nexus 4 under the Devices & Drives section of "This Computer" (My Computer had a better ring to it lol) First I tried rebooting both my laptop and my Nexus 4, then I tried uninstalled the drivers, rebooting, re-installing, and then rebooting again. Did that like 4 times now, each time re-downloading the drivers, and doing an MD5 hash to create a Checksum, and checking them each time. Also to no avail. ADB shows my device serial number when i enter : ADB Devices, but says it's unauthorized, so if I try anything like: ADB Reboot Bootloader, it says Device is not authorized.
So ! I don't understand wtf is going on. Was working fine before. The drivers are up to date, I just flashed the Official OTA image, and was on the leaked image prior to that. Then earlier this evening I switched to the newest version of the Nexus 5 Port, and everything was still working fine, hadn't made any changes in a couple hours before this happened. When I install the drivers, It acts like it worked. Instead of saying "NEXUS 4" under Other Devices in my Device Manager, it says Composite ADB Interface under Android Devices and MTP under Portable Devices. Sometimes tho the MTP entry will still show the Yellow Exclamation Point. But goes away. Don't know whats up with that either.
Also, it wont let me install drivers unless I am in MTP mode, which Usually you can install them regardless (tho I never tried in Camera mode, I am just assuming about that one) Usually I install drivers without MTP or Camera modes checked, but now if I try it, it says that Windows Cant find the Drivers, even tho I am obviously browsing for them myself and selecting them. And just now I tried updating instead of re-installing them, and it keeps saying that Windows has determined they are the most up to date.
So I am out of I ideas. I even updated windows media player cause that's what fixed my issue on Day 1 of running Windows 8.1 when it wouldn't recognize it at all. So I don't know. Sorry for the long post but I wanted to make sure I got everything in there so hopefully someone can narrow down what the issue is. Cause I've been at it for 3 hours, haven't slept yet, my Nexus 5 gets here today, and I need to get this fixed before I sell it to my buddy. Its brand new, only 15 days old.*
Any thoughts ?*

First, connect your Nexus 4 and use Device Manager to uninstall both MTP and ADB devices, make sure to check the box to delete the driver files as well. Then uninstall any other usb or adb drivers for other Android devices.
Then disable USB Debugging on the phone and get MTP to work first, Windows should be able to install it automatically.
For ADB, Windows 8 will not allow to install unsigned driver. To install unsigned driver, reboot Windows 8 into Advanced startup and press F7 at the menu to disable driver signature (Google it if you don't know how). Although you could install Google USB driver which is signed I think, I recommend using Universal Naked Driver (link in sig.)
ADB Devices, but says it's unauthorized

You need to authorize it from your phone, when you connect your phone to the PC with USB Debugging turned on, a toast message on the phone will ask you to authorize the device.

ok I am gonna try that now. And as far as the part about my phone being unauthorized. I already knew about the notification that pops up, i was waiting for it to happen. Never did tho. Maybe it will happen after I do the rest of what you said. thanks, i will post my results in a min

no matter what i do, i cant get MTP working. When i uninstall the ADB entry in Device Manager it gives me the check-box option for removing drivers as well, but not on MTP. And now it wont even give me the option to uninstall, update, or anything at all, even tho I uninstalled it already so it should at least give me the option to install drivers. Even tho it's showing up in Device Manager as a Portable device, if I look in Printers and Devices, it shows up as unspecified device. Disabled USB Debugging, and all that. it says its working but it wont show up in My Computer>Devices and Drives still. For some reason ever once in awhile it will pop up with the Yellow Exclamation Point tho, only for a brief second tho. other then that, its shows it like it's running correctly. Also, nothing pops up saying that windows is installing drivers when i plug it in. Which in Win 7, XP, etc, it always did. Does this not happen in Windows 8.1 ?
Also, under Driver Details, which is the only option it lets me click on MTP, it says the drivers are from 2006 lol
Update - Just reinstalled the drivers for ADB and enabled USB Debugging, and everything is still saying its working even tho its not. But when I take my phone out of MTP mode it shows up in device manager under "Other Devices" as Nexus4, with a Yellow Exclamation, and it gives me the option to update drivers, so i tried, but it says Windows Can't find my driver. This is very frustrating.

Had this problem aswell, which was caused by the N version of Windows 8 versions.
These versions dont have Windows Media Player istalled, which is needed for MTP to work.
So to fix your problem you need to download that latest Windows Media Player (WMP) from microsoft and install that.

I dont have the N version, I have WMP installed, i mentioend your fix in the OP. Had to update it, and it worked. It was working fine for the last few days, then it stopped working suddenly

double post, sorry. dont know why that happened.

Vouch. Since I use win8.1 (no n version) Mtp doesnt work. I tried all known drivers, disabled driver signature and so on. The only working combination for me is Usb Debugging + PTP. Then I use file manager to cut the files. Airdroid would be an alternative as well.

update - SOLVED * Kind of.....I say kind of cause I still don't know what caused it but apparently Flashing to the Nexus 5 Port fixed the issue lol. I am assuming something pertaining to the way USB connectivity is controlled by Android got corrupted, and a fresh install was in order. Whatever it was, it worked and i am back in business. thanks to all those who attempted to help.
