Unable to Root - X Style (Pure) Q&A, Help & Troubleshooting

I've tried the two methods manual and windroid toolkit.
I'm not able to get the adb drivers recognized under device manager .
I've downloaded and installed the moto device manager exe. That suppose to have all drivers
When I update adb drivers which falla under android device in device manager and choose my driver location it only gives me MTP And it fails to update
My phone model number shows under Portable devices just fine .

Maybe put your phone on the bootloader screen then plug in the phone to the computer and try to install the drivers again if they don't install by themselves...... Just a thought running thru my head at the moment so no promises this will work for you
The only other idea I can think of is to download the SDK installer and try the Google drivers

In device manager, try removing and or checking which driver is installed. I have had problems where it was recognizing and using the universal android driver versus the moto one.
To your process above, if you uninstall the existing adb/fastboot driver through device manager then reinstall the moto ones, it should hopefully port over.

[USB Drivers] Galaxy S GT-I9000 (Working on ICS)

Hello.
And bacon and spam:
I've recently upgraded my SGS to ICS (ICSSGS ROM) and started to develop a simple application.
So, now i've got to the point that the emulator starts to show its limitations, so i need to debug directly on the real device.
Well, i've been trying to make ADB recognize my phone, tried several usb drivers from several sites, none of them worked.
After several hours spanking windows, it's finally working (yes! almost 6 AM in the morning!).
What matters:
So, to anybody who have the same problem as i had, do the following:
0. Uninstall any drivers that you've tried before.
1. Extract the zip file that i've uploaded to anywhere you like.
2. Enable debugging on your phone and connect it to PC throught the USB cable
(Just connect it, don't mount)
3. On your computer, click Start -> Right click on "Computer" -> Manage
This will open the "Computer Management" window (it might take some seconds to load).
4. Click "Device Manager". Now you should find your device in the list. It must be really easy to find. It's called something like "GT-I9000" or "GalaxyS" and it has a yellow warning sign next to it.
5. Right click on it and choose "Update Driver Software". In the window that appears, choose "Browse my computer for driver software". It then asks you where is the driver.
6. Click the "Browse" button and choose the folder you extracted from my zip file.
(If you didn't change it, it must be called "Android Composite ADB Interface")
7. Click "Next" and cross your fingers. If you're lucky, it may work for you.
Final notes:
1. I'm not responsible for ANYTHING. Whatever you do, it's your own choise to do it. I guarantee absolutely nothing.
2. This is was tested on Windows 7 - 64 bits with Team ICSSGS RC4.2 ROM and Semaphore ICS 0.9.1 Kernel.
3. Have fun.
4. If you try this, please answer the topic and tell everybody if it's working for you (mentioning your Windows version and what ROM you use).

Missing file when installing driver on windows 7 x64
Hi,
I have recently installed the most recent Dark Knight ICS 4.0.4 build to my Samsung Galaxy S. The ROM seems very good but I'm an android app developer and need to be able to debug my applications on the device via USB.
I have tried the driver provided in the thread which won't install due to a missing file according to the Windows 7 x64 driver install wizard. The exact message is displayed after step 7 and says:
"Windows found driver software for your device but encountered an error while attempting to install it."
"Android Composite ADB interface"
"The system cannot find the file specified".
Is there a file missing in the package? Has anybody managed to get this driver working?
Cheers,
Ben
Does it say that it doesn't find a controller or that is there a missing file?
Anyway, please try this installer and let me know if it works for you:

What's wrong with the Nexus S drivers available with Android SDK?
Google USB driver, R4 developer.android.com/sdk/win-usb.html
The SGS will present it self like that when it is running ICS/CM7/CM9.

Nevertheless thanks for your approach. I'll test if it works with the SDK Updater.
I'm going to test in my desktop this weekend to check if it works with it.
I have the same problem, but with WIndows 7 32 bit. Drivers from discusion doesn't work. Don't you have some for 32 bit?
I found SDK Components on developer.android.com, where is Android driver which suppose to work, but unfortunately ODIN still do not see phone.
I also have the same problem but mine is worse because my phone is completely down after I tried to restore from a GB ndriod backup failure , phone won't boot , cannot boot into recovery only in download mode but no way my 4 x computers would detect the phone now ....tried using heimdall in linux as well as sdb, no go....so sad...help...

Using Google USB drivers finally worked for me. They can be optionally installed with Android SDK using SDK manager (extras). After installation drivers can be found in <sdk>\extras\google\usb_driver.
Just follow the instructions in the first post to find your device from device manager with exclamation mark. Need at least one reboot to work and I also redirected the driver installation process to Google usb driver directory but now ADB finally recognizes my SGS (MyICS, Android 4.0.3).
Edit: Operating system Vista 64-bit
[Currently stuck in "error: device not found" while trying adb push -command. I will update if I find a workaround. Probably something to do with inf-file.]
For alternate .inf -file (optional):
Google "usb-drivers-not-working-after-flash-latest-rom-ota" and see post #12 to see alternative inf-file. Some have managed to make adb recognize the device with that file, but I have at least this far been unsuccessful.
Edit: Problem above was caused by me being stupid and trying to use push in shell, which caused phone unable to locate host system folders. I don't know if that inf file has anything to do with drivers working now, but go ahead and try it if doesn't work with the original .inf

This worked for me
The very important thing is that newest Google USB driver is in
Code:
[B]<android-sdk>/extras/google/usb_driver/[/B]
location, not in
Code:
<android-sdk>/usb_driver
It really makes the difference !
these drivers only worked once...
all the other times killing and starting over adb i was getting error messages like "device not found" and "protocol fault" even though adb devices was listing the device online.
apparently i connected the phone to another USB3 port on my pc (front panel) and that was it!! it now works every time i type adb shell or adb devices.i no longer get any error messages.rather weird
anyway..i also wanted to be up to date with everything so i uninstalled all related software like the older java 6 jdk, Android SDK and the drivers mentioned above.
i followed the procedure below and installed all the latest packages:
latest java 7u5 JDK, the latest Android SDK (nstaller_r20.0.1-windows.exe) then ran sdk-manager and loaded http://developer.android.com/tools/extras/oem-usb.html#InstallingDriver google USB drivers rev 6. then installed these drives so i got the ADB composite interface on my device manager and it all works fine now.
I recenelty installed latest ICS , and SDK recognizes my phone as ACER ADB , when I'm pretty sure its a Samsung I9000 . I tried uninstalling the ACER ADB and install the one that the guy posted in the first post , and it didn't work , it said this driver is not compatible , oddly it reinstalled ACER ADB though. I can't even uninstall it at all , I removed all my Samsung drivers , and everything else I installed for Samsung , and its still there , I even tried removing the GOOGLE USB drivers , still there.
Neendless to say that the phone doesnt connect to the PC at all even though it says everything is alright. For example i got ths gPAD app , which uses the USB with Debugging to turn the phone into a mouse , but it says its not connected even though it is.

[Q] Nexus 4 ADB on Windows 7 Home

After several hours of frustration, I'm just going to ask.
I have USB debugging enabled. When I plug in the Nexus 4 Windows auto installs drivers for MTP.
It's listed under portable devices in device manager. I am trying to uninstall the driver and install the Naked driver. But as soon as I uninstall in device manager, Windows reinstalls, despite me having turned off auto-installation of drivers. I am not able to use the advanced method listed here http://www.addictivetips.com/window...utomatic-driver-installation-in-windows-vista because gpedit.msc doesn't exist for Home users.
I have unplugged the device and manually put it into Fastboot and plugged it in. Windows does not try to autoinstall drivers. I am able to install Naked drivers and the device appears as "Android Phone" in device manager.
How can I proceed?

The problem is that Windows is auto-installing the driver as soon as I uninstall it from device manager. I have this setting disabled in Device Installation Settings but nevertheless it continues auto-installing.

When you plug in your n4 in your pc, does it allow you to open the folder for your phone. If it does the drivers are installed. Mine n4 did the same as you when I plugged it in my PC, and did show Android in the device manager.
Use the nexus 4 toolkit to do it.

It's showing up as portable device, not as Android when MTP is connected. If I manually boot into fastboot, and connect to PC it will show as Android.
Nexus 4 toolkit doesn't work. When I connect the device, it still only shows up as MTP device connected.
How can I stop the "Nexus 4" driver from auto installing the MTP driver?

You could try this installer. If a prompt ever says not to install a driver just do it anyway.

I was having the same issues, toolkit didnt work, auto kept auto installing MTP only, junefabrics.com didn't work by itself, LG drivers didn't work. finally I tried the drivers in sig and adb was installed but the tool kit still didn't recognize it. I ran the one from junefabrics.com after that and hit no to not reinstall the drivers when it asks, but it's hanging when installing pdanet on my phone.

im in the same boat
I'm having these same issues. Very frustrating.
Just fixed the problem by following the directions in this post - http://forum.xda-developers.com/showpost.php?p=34154052&postcount=7
His instructions about cmd prompt didn't work for me, so in device manager I selected View -> Show Hidden Devices.
I removed all android, nexus, other android phones and then reinstalled the drivers via the toolkit. Seems to be working so far!
The MTP driver will always install as that's nothing to do with adb. If you open Device Manager it should have the other option - you then manually install the driver by browsing the the drivers folder when using the 'Update driver' option in the right-click menu when you click on it in Device Manager

its caused by the android 4.2.2 update...
For anyone still having problems, these are the steps I followed that fixed it for me. (After updating to the latest sdk version and downloading the google usb driver)
1. Uninstalled the driver from Device Manager
2. Let it automatically install the generic 'MTP device driver'
3. Right clicked on the new device and selected 'Update Driver'
4. Selected 'Have Disk' and pointed it to [android-sdk-dir]\extras\google
5. Watched an 'ADB' driver install.
6. Opened Eclipse to successfully run on my N4.

Nexus 4 ADB Connection

I am trying to connect my Nexus 4 to my PC and use the ADB commands. I have the following problems:
ADB driver is installed and "USB Debugging" turned on the Nexus 4. Device shows up on Device Manager, however "adb devices" does not list the device and unable to communicate with the attached device.
The Nexus drive, regardless of MTP or PTP disappears from Windows Explorer when "USB Debugging" is turned on, Turning off "USB Debugging" brings back the drive.
USBView shows the device with a RED light, but it appears working on Device Manager.
I do not have this problem with my other laptop and desktop.

I had sort of the same problem, try uninstalling the driver in device manager, then unplug and replug your USB. Then when you plugged in the USB go to device manager and right click on the device and click scan for hardware changes. See if that works.
I'm not sure if this is a problem caused by windows update or the new updated SDK, but it has been a big problem for me.

OK try right clicking on the the device in device manager and choose update driver, then Browse my computer, then let me pick From a list of devices. After choose have disk on and find the file where your USB drivers are and click next. It may prompt you that windows can't verify the publisher Just click install this driver software anyway.

This is what I did and waited for the PC to install the adb drivers.
I plugged the phone in and with the USB plugged in turned it off while holding the volume up and down keys. This made my nexus 4 go into download mode and the PC automatically installed the adb drivers. After I just unplugged and held the power button to restart the device hope this helped.

When you uninstalled what's there now, you did make sure to check the box that will remove the old drivers from your PC?
Just in case, HERE is another source for the drivers.

Thanks to everyone for their help.
Just to confirm I have already tried:
Uninstalling the ADB driver via Device Manager and selecting "Delete the driver software for this device" and rebooting.
After reboot, Windows could not locate any drivers and I manually selected the drivers found inside the SDK (08/27/2012,7.0.0000)
The device shows up on Device Manager as working but does not work with adb commands. However, fastboot commands work!
I tried the above with the Naked Driver and had the exact result.
If I boot into the bootloader, I am able to run fastboot commands perfectly!
I have already ruled out my USB port as it works perfectly on VMware.
I am thinking my Windows 7 is messed up somehow and re-installation is looking like the only solution :crying:

Thanks. I tried version 16.01 and still have this problem.
The problem is whenever I uninstall/install the ADB driver or disconnect/reconnect the USB, **ONLY** the "Nexus 4" appears on the Device Manager which I manually install the ADB drivers to. There is not a second "Nexus 4" on the Device Manager for the MTP or PTP.
On my laptop when I remove all drivers and reconnect the USB cable, I always see 2 "Nexus 4" listed on Device Manager. One for the ADB interface and the other for the MTP or PTP.
Please help!
Any ideas please?
Any Solution to ADB connection problems?
Hi was there any solution to this, as I seem to have the same issue.
I have tried different drivers and MTP & PPP modes as well as loading the PDAnet drivers and software.
Each time now I take care to remove all the drivers and also delete the drivers in all modes (Android running and Bootloader running)!
MTP & PPP load different copies of the drivers.
I can get either "Nexus 4" showing up in the device driver or "Google ADB Interface" or Android ADB interface" according to the driver loaded.
I can see the device when Android is running ie "ABD Devices" gives me the serial number and connected, then I can send an ADB command "adb Reboot-bootloader" the Nexus then reboots into the bootloader screen, the device driver changes to the bootloader driver (installs if not installed) however then I loose connection to the Nexus phone! "ADB Devices" returns none connected.:fingers-crossed:
I also tried unplugging and plugging back in the phone in bootloader mode but do not get adb to see the handset or it to react to commands.
I'm just about ready to try a toolkit to see if I can get past this roadblock!!!
Current computer is Win7-x64
This weekend I will try on a different computer.....Win8-X64
All comments appreciated
That's because you cant use adb when in boot loader. You use fastboot

Win 10 x64 - Motorola Device Manager failed to install the correct USB driver

So i finally got around to setting up my laptop anew, and i ran into a little snag. I've installed the Motorola device manager 2.5.4.
My XT1562 is not correctly installed as such when connected... (yes, in PTP mode, adb enabled too)
The phone knows it is connected by USB and charges, it works fine on other PCs
Reinstalled Device Manager, nope
Trying different USB port didn't help
Tried different USB cable for the heck of it
Device Manager shows Android Device "Motorola ADB interface" and one unknown "MTP".
Device shows:
The drivers for this device are not installed. (Code 28)
There are no compatible drivers for this device.
Using the auto update for drivers doesn't work. Manually Specifying the folder for the Motorola Device Manager doesn't work, i checked, there are no drivers lying around in there...
To manually specify the driver i would have to know exactly which device that thing is supposed to be. Hm actually let me check that on the other PC brb
EDIT:
Well, ive never even installed the motorola device manager on the pc (win7 x64) and it just works. Does have the ADB device as unknown in Device Manager.
If you are using Windows 10 or win 8.1 follow this guide to disable driver signature enforcement
https://www.youtube.com/watch?v=71YAIw7_-kg
For abd drivers
http://adbdriver.com/downloads/
Then reinstall Moto device manager
I've had them installed with signatures before (It was Win10 x64 before too) no problem. Did they mess that up? Thanks ill try it
EDIT
Didn't work. Rebooted with sigs off, reinstalled 2.5.4, no difference
EDIT2: There was no driver signature warning either
Riiight, after some tinkering (including a driver backup from w7 and restore to w10 solution) i figured out the actual problem. I've installed Windows 10 N, and the optional media pack is required for these drivers to work. Go figure.

Nexus 6P won't install on any system

My dad has a Nexus 6P.
When he connects it to my Windows 10 PC or his own Windows 10 laptop, nothing appears in Computer (any USB mode on the phone).
Device Manager shows a yellow exclamation mark next to the device.
Trying to reinstall shows that an error occurs whilst installing 'MTP Device' (service installation section in INF invalid).
I have tried installing the standard Android USB drivers, no luck.
I've tried with and without USB debugging mode enabled.
Any ideas?
Is the device having any issues? Like is it boot looping or just dead?
If not, it definitely sounds like a driver issue. Open up your device manager and delete any Google / Android drivers and then reboot the PC. That part is pretty important. PCs can be a little wonky with drivers. After that install them via the method posted in Heisenberg's guide. Reboot the PC again and then try.

There are no drivers to uninstall in Device Manager. If I right-click on the (exclamation mark) device in question, I simply get 'Remove', which 100% doesn't uninstall drivers, presumably because no drivers are installed.
Also, the instructions there require a load of stuff (CMD, platform tools, Android debug bridge and all that rubbish), just to install the drivers. I doubt it's that complicated.

I've given you the tools to get it up and running, whether you choose to use them is up to you. If you read the guide, you'd see that you don't need to install the entire SDK. It's one of the first things mentioned in the drivers section. Good luck.
Edit: Read your post again. Seems you're a little confused. CMD is a program already on your Windows PC. You must use it in order to use fastboot. Fastboot and ADB are literally the drivers you need to install. Not "rubbish." Read that guide and take it to heart. There's a lot of learning ahead for you, no offense.

Even if you don't wan't or need ADB/Fastboot, a link to the standalone USB drivers is provided in the guide. If you still have issues, an existing driver installation is likely causing the problem. There is a free tool called USBDeview you can use to get rid of the conflicting drivers.

My dad has a Nexus 6P.
When he connects it to my Windows 10 PC or his own Windows 10 laptop, nothing appears in Computer (any USB mode on the phone).
Device Manager shows a yellow exclamation mark next to the device.
Trying to reinstall shows that an error occurs whilst installing 'MTP Device' (service installation section in INF invalid).
I have tried installing the standard Android USB drivers, no luck.
I've tried with and without USB debugging mode enabled.
Any ideas?

If you just want to be able to transfer files back and forth between computer and phone you can try installing Huawei's Windows software which should download necessary drivers. I didn't personally find the software all that useful but it's another option if you aren't looking to do anything complicated with your phone.
