Windows 7 x64
Galaxy Nexus i515, BROKEN SCREEN, USB DEBUGGING WAS NOT TURNED ON. The phone is completely stock I just turned it on and used it until I broke my screen. Screen lock is on.
I have been trying to access my phone, using Fastboot, to wipe it before I send it in for warranty. I can not seem to do this at all. It seems that I can not install the drivers because I have not enabled USB debugging. Is this true? I have been following this guide : http://www.teamandroid.com/2012/07/30/how-to-set-up-adb-fastboot-with-android-sdk/2/ When i go to manually install the drivers, from SDK, I get, "The folder you specified does not contain a compatible software driver for your device. If the folder contains a driver, make sure that it is designed to work with Windows for x6-based systems." I then tried the driver from Samsung and got the same response.
So then I hold VOL+ _ VOL- and Power and tried to install the drivers for Fastboot with the same outcome as above. Also when I boot in Fastboot mode the drivers that are installed make my phone a modem. The driver is called, "SAMSUNG Mobile USB Modem." I can not get this to change.
So to summarize I can not get the ADB Drivers to install, because I do not have USB Debugging enabled, that in return will not allow me to install Fastboot Drivers because when I plug the phone in the computer sees it as a Modem.
Any suggestions? I am just trying to erase the info on my phone I have given up all hope of recovering any data.
Thanks,

USB debugging drivers/interface have nothing to do with fastboot drivers/interface. What's a screen lock?

I meant a screen pattern lock. When you wake up the screen you have to connect the dots in a certain pattern before your screen unlocks and you can use the phone.
As far as, USB debugging drivers/interface having nothing to do with fastboot drivers/interface, then what am I doing wrong? I can not get my computer to see my phone as an android device.

I know what a screen pattern lock is.
Uninstall all drivers, reboot pc.
Assuming device is off: press power+vol up+vol down, until you feel the vibration. Wait 2 secs or so. Device will be in fastboot mode.
Read this thread, i say again, READ this thread, obviously start with the first post! - http://forum.xda-developers.com/showthread.php?t=1812959
Thanks for the link. I read it and followed instructions for installing the drivers. Here is what I did:
1.Uninstalled all drivers
2.Rebooted my PC
3.Downloaded these Drivers, as suggested: http://forum.xda-developers.com/showthread.php?t=1379875
4.Followed these instructions, on how to install the driver without windows trying to find one automatically: http://forum.xda-developers.com/showpost.php?p=29044502&postcount=735
Everything seemed to go well under the Device Manager, when I plug my phone in in fastboot mode, it shows Android Phone -> Samsung Android Interface. This is way better than what I had before, when it was showing up as a Modem. Now when I try to use fastboot.exe and I type "fastboot devices" nothing shows up. I reset the computer and replugged in my device, in fastboot, and the same thing nothing shows up in fastboot.
Thanks for you help.
Did you miss the part about having to feed windows the same driver again, when connecting the device for the first time, in FASTBOOT MODE?

Not sure if I understand what your asking.
I followed all of the steps here: http://forum.xda-developers.com/showpost.php?p=29044502&postcount=735 I connected the phone booted normally and let windows find a driver so that the driver reads Portable Devices -> Galaxy Nexus. Then I unplugged the Nexus and booted it in fastboot mode and plugged it in. Next I followed the directions to install the Universal_Naked_Driver, in fastboot mode. I can not install the driver for ADB because I can not enable USB Debugging with my broken screen.
Thanks Again.
Why is it so difficult for people to understand that USB debugging has nothing to do with anything outside the booted OS?

W8 a sec, do you even have your bootloader unlocked???
You said you're running stock, so that should have been my first question, because to unlock your bootloader through the usual way, you need to confirm a dialog on the device... which in your case, doesn't have a working screen.

Lets see:
That post shows how it's done, correctly. (I think, from what i've read)
pay attention to part 3)
3)
NOTE:
- The method described here can be used to install the "Samsung Galaxy Nexus ADB Interface" driver as well as the "Samsung Galaxy Nexus Bootloader Interface" driver.
- Differences between the two procedures. One is done with the phone booted up normally and "USB Debugging" is enabled, and the other is done when the phone is in fastboot. I will cover the "USB Debugging" part here.

We will now install the two drivers that efrant talked about in his post.
A) (FOR ADB - WHEN RUNNING ANDROID OS):
Enable USB debugging on your device
- Goto Settings > Developer Options > Check "USB Debugging"
- Connect device, manually update driver to Naked driver by 1wayjohny, done. On 4.2 and above, you'll need to confirm that you accept the host's (your pc) RSA key.
B) (FOR FASTBOOT - WHEN RUNNING FASTBOOT MODE)
boot into fastboot mode - power off phone and hold vol up + vol down + power
Click to expand...
Click to collapse
Both for A) and B), you need to do the "Update drivers manually" part!
Right now, your only option is B), that is to use fastboot to either:
- Flash stock images.
- To get your data back, boot a custom recovery (which won't require the RSA key confirmation for ADB) from fastboot, then use ADB to pull your /sdcard/ or whatever.

I am learning this ^. I am having trouble getting my computer to see my phone, in fastboot mode. All of the instructions that I have read start with installing drivers for ADB, which requires the phone to be USB debugging mode, and then the drivers for fastboot. So I thought my trouble was, since I can not install the drivers for ADB, and that I was having trouble with all of my drivers, that it was probably the fact that my phone can not be put into USB debugging mode. I now realize that USB debugging has nothing to do with fastboot, as fastboot is before the OS is booted. I am still just having trouble with my fastboot driver and seeing my phone with fastboot.exe.

No my bootloader is not unlocked. Is this the reason that my phone is not detected by fastboot.exe? Do I need to unlock my bootloader?
I have been trying option B, as I know this is my only option. I have been doing the "Update drivers manually" part I even tried on another PC with windows 7, to no avail. What ever I seem to do I can not see my device in fastboot.exe.

No. Fastboot should be able to see your device if the proper drivers are installed. Fastboot is REQUIRED to unlock the bootloader

If you used odin to flash something, that will unlock the bootloader. Flashing a section of edited param using OMAP flash will also unlock the bootloader.
Beamed from my Maguro.
I also have the same problem with my galaxy C5.

My galaxy C5 is also not recognized as a bootloader interface while in fastboot mode, after installing all the drivers correctly. Samsung usb driver v1.5.63.0 makes the changes i think, and it makes it as a modem instead of bootloader. maybe the solution is i have to manually update the driver of that modem into bootloader, right click on the modem in device manager and change it's driver into bootloader of your phone, maybe it works. I will try it this way.
Let me know if this solution has worked for someone.
Thanks
I already enabled OEM Unlock and USB Debugging in Developer options.
then I connected my LG G4 H811 to PC and confirmed MTP.
adb devices just shows:
List of devices attached
If I select USB charge instead of MTP, the adb devices shows:
List of devices attached:
LGH811***** offline
Looks like MTP mode adb cannot connect to H811 at all.
Does anyone know the reason? Really need to unlock bootloader and then root my phone.
Thanks

its beacause your mobile's Debugging didnt alowed that usb connection. when u type 'adb device' there should be a popup on your device asking to connect to pc. choose Allow. it will be online hen.
Thanks for the reply!
But there is no popup on the phone when I type "adb devices". The only popup I see is when I connect PC and phone with USB, a popup on phone asks me "Allow this computer to access your phone data?" I choose "Yes"
Any help will be much appreciated.

If all the checks boxes are ticked, try revoking USB debugging authorizations. Connect your device as MTP (try PTP as well) and try to adb devices again and see if you get the pop up on your phone. Last option would be to boot into recovery via button combo and reboot into the bootloader from there.

I tried all of your suggestions, none of them work.
PTP/USB charging mode, adb devices shows:
List of devices attached:
LGH811***** offline
MTP shown no device attached...
I did get into download mode (bootloader mode I think) - screen says Firmware Update, do not unplug the USB connection until the process is complete
Then I tried to run fastboot oem unlock, it stucks at
< waiting for device >
and there is no change on phone screen.
Any other ideas? I really need to root my H811. Appreciate any suggestions!
Change to PTP mode.

It sounds like your usb drivers ars not properly installed. I would try uninstalling and then reinstall. Did you happen to install LG Bridge?

Download mode is not the recovery. If you have TWRP installed as your recovery, power your phone off completely and disconnect it from the computer. Then press and hold volume down and power. Keep holding and when you see the LG screen, release only the power button and press and hold it quickly again (you should still be holding volume down). This'll take you to the factory reset screen, select yes twice and you should be taken to twrp. REMEMBER, ONLY DO THIS IF YOU HAVE TWRP INSTALLED!

I followed all steps in the thread you list. I am stuck at "adb devices" where I didn't see my phone is listed if I connect with MTP mode. For USB charge or PTP, I see devices but it is offline.
With this problem, I cannot get my phone reboot into bootloader mode and run oem unlock/twrp.

Did you tried revoking the usb auth?
http://forum.xda-developers.com/g4/development/unlock-bootloader-h811-20o-t3459285/post68630578
Do you receive a popup afterwards when connecting the usb cable?
PTP or usb charge should be fine.
What OS are you running?
.
I am using Window10 on my PC.
I made a tiny progress: I installed LG Bridge software and it updated LG driver on my PC. Now when I connect phone to PC with USB (of course I choose "ALLOW" for popup USB Connection Allow this computer to accept your phone data?). Now I see devices under MTP mode but it is still offline so I cannot boot it into bootloader mode. There is no popup when I run adb devices.
I tried revoke USB auth a couple of time, no luck
Finally I made it work!
The reason is adb I was using is too old
I changed to 1.0.31 then it works w/o any issue.
Thanks for the help all the way! I really appreciate your patience.

Good Afternoon,
I took my Pixel C to a CEX store a few months back, just turned it on and they set a PIN and I cannot get it to boot. I tried going into recovery mode to factory reset but get 'no command'. The bootloader is locked and it looks like USB debugging is disabled because I cannot get my computer to recognize it despite having adb/fastboot installed and the Google USB drivers.
Have you any ideas about how I can fix this please? I can get into fastboot mode on the device but cannot get WIndows to recognise it is there.
This is now resolved, I had to add the device ID to android_winusb.inf - fastboot then recognised the device and I could perform a bootloader unlock which in-turn erased the tablet and allowed me back in.

I don't think usb debugging is necessary if you select flash mode. Just check that drivers are installed in pc properly or not.

It surely is a problem with pc. Try using your friend's pc.
One another thing, can you enter fastboot mode?
Type fastboot devices in cmd while connecting your phone with vol- button.
I am trying for the first time to root my 7t pro McLaren, and I ran into a problem. When the boot loader is turned on, and I use fastboot devices, nothing happens. When I do adb devices with it powered on, it shows that its connected. I tried to use the oneplus usb driver update, and nothing happened. does anyone have any solutions? I have OEM unlocking turned on and SIM permantly unlocked. If it helps I'm running on windows 10.

Hi.
What you want to do exactly?
To Root open bootloader as first.
Developer options /Default usb configuration/ file transfer. Then check if pc "see" your device. fastboot fastboot devices. If visible then u are at home let's say
Make sure your USB port on the phone is clean using compressed air. Though if it works with ADB it should also work in bootloader
