Make sure USB debugging is enabled in developer options
Then do this: Setting's > Storage > Click the ellipsis top right of the screen the 3 dots) > Select Camera (PTP)
Now when you connect your phone to your laptop etc you should get an address id authentication prompt, tick the checkbox and click ok.
You may also need to install android sdk if you don't have correct drivers or whish to use cmd prompt adb

Cool debugging is enabled and SDK is installed but haven't tried the camera option. Will try after work and update. Forgot to add that adb work its only fastboot that isn't recognized.

Fastboot only works in bootloader. To get to bootloader, power off, then hold power and volume-down. Does that work?

That's just it. Bootloader works just fine but its not working on my PC. It recognizes it as android boot loader interface but says device cannot start so I can't do crap with fast boot Lol that's why I'm confused I've never had this issue

How do you know that drivers installed correctly? Was there a popup?

Either the drivers that got installed are the issue or you have cable/port issues.

I actually just gave up with me PC and switched to my wife's which I had done a ton of rooting before including my original nexus 7 and it went smooth without a hitch so Idk what the problem was

[Q] Can't get ADB to work, have tried everything

Hi All.
I'm hoping you can help - I've searched far and wide (including the awesome little "Here are the similar threads we found" box that appears when you create a thread) with no luck.
Basically, my phone is as in my signature, but I can't get ADB to work. I go "adb devices" and it doesn't list anything. adb.exe is working, and I can access it and everything via command prompt, but no dice on actually using it.
Not sure if this is helpful or related, but fastboot works 100% perfectly which is what confuses the heck out of me.
I'm running Win7-64Bit. The only abnormality is that Device Manager lists "Android Phone" as an unknown device, yet I can mount USB storage (both in Recovery and when booted into Android) and access the SD-Card.
Trying to locate drivers for "Android Phone" via Windows Update, as well as looking in "C:\android-sdk-windows\extras\google\usb_driver" doesn't assist (drivers are in the directory). Not sure if that is related, but it might be.
Thanks for any and all replies

I'm afraid windows 7-64 bit appears to be the problem. I have the same problem but, as yet, not the solution. If you have access to a computer running a different version of windows you should be able to get it to work on there!
Sorry i can't be any more help.
Windows 7 64-bit IS working - I am using it and it works without problems.
Do you have USB Debugging enabled in Settings > Application > Development?
Also: try this driver & instructions: http://unrevoked.com/rootwiki/doku.php/public/windows_hboot_driver_install

Hi Dave, thanks for the reply.
I definitely have USB Debugging enabled - I also am 100% sure that I have installed the hboot driver before (I did it when rooting for the first time ages ago), and can confirm this by booting into Bootloader and having "Android Bootloader Interface" appear as a known device.
Also, with the HBOOT-Driver, it lists the phone as "Android 1.0" when Unknown, whereas my situation lists "Android Phone" as the unknown device.

Same here.
Have you added the environment variable for the sdk directory? It won't work if you don't.
Also.. install .. HTC Sync.. .and try.. and again uninstall only HTC sync.. and leave the HTC driver and try
I've had issues getting it working too and haven't quite figured out the sequence to get it to work. All I remember is the Android SDK drivers don't work, you need to use the HTC ones. You don't need to uninstall HTC Sync (try re-installing it though). You might then need to run update drivers on the unknown device for it to find them.
I can confirm that it does work with HTC Sync still installed. I sometimes find ADB devices takes a few attempts or restarting ADB to actually work.

What i meant is that windows 7 seems 64bit seems to cause more problems than any other windows os. I had a windows 7 64bit computer and after days of pratting about i managed to get it working now, further down the road, and a bit more knowledgable(i think!) i have a new more powerful windows 7 64bit machine and i can't for the life of me get it working.
I know run adb from my wifes vista laptop and had no trouble whatsoever in setting this up.
If u tried "everything", u better don't ask for more ;-p

Can't get Fastboot to work

Ok. I can't get fastboot to work. WIndows 10 laptop. Disabled driver verification. ADB works fine and reboots into bootloader but once in bootloader no fastboot. I've got an "Unknown Device" in Other Devices in Device manager and I've tried to assign the google driver manually but it's not recognized as a driver for the device
I've removed and reinstalled drivers pre and post driver verification
I tried adding PIxel C lines to the driver INF file as instructed on stack overflow
I don't know what else to try. And i've tried on two different computers???
Help please.. thanks
I fought with this for ages today. To start with, I have the Wugfresh Nexus Root Toolkit installed. Now, when in bootloader, go to the device manager on your computer. Find the Pixel ("Unknown Device") and right click > Properties > Driver tab > Update Drivers > Browse Computer > Choose From List > WugFresh Development\Nexus Root Toolkit\data\Drivers > and pick the one that says something about the bootloader. Sorry, going off memory here. Now you should be able to get that one installed, and Fastboot will start showing up when in the bootloader.

That's OK. No problem. Did you try the steps in post #5 above?
Which operating system are you on? What worked for me on Windows 10 was to give up after several days and use a Windows 7 computer. I read everything and tried everything and I could not get Fastboot working on this device with Windows 10. I used every toolkit, every driver version, toolkits that install multiple driver versions, Minimal ADB + Fastboot, and who knows what else. If a well-documented end-to-end solution to this ever appears I'll be really grateful.
FWIW, it was my frustrations with this Windows driver nonsense, that eventually drove me to abandon Windows entirely. Been on Ubuntu for several years. No regrets.

It's very annoying, there seems to be a few reasons it fails. Cable, 3.0 usb ports, windows 10 drivers. I get different results with different cables in different types of usb ports. Also switching to PTP seems to work using a usb 2.0 port with a standard usb 2.0 A to micro with a micro to c adapter. Charging and MTP fail, but at least ADB and Fastboot respond.
I am going to try to edit the win10 driver using this post as reference.

I came to the same conclusion, but after a reboot it was unrecognized again.
Only way I can it to stick is installing the 2nd option drivers via skipsoft toolkit. Connect pixel c via 2.0 port and cable to PC. Switch to ptp. Then manually force install driver choosing have disk using bootloader option. From then on it works using ptp.
What I am able to see using USB Device Tree Viewer, is that when I plug in my Pixel C to my ASUS Z97-A blue usb ports with USB debugging enabled, it can not identify it. Those ports use Microsoft Windows 10 drivers for the Intel USB 3.0 eXensible Host Controller - 1.0. Which is what is causing the failure, not the Pixel C drivers. When I updated my other green USB ports driver, windows used the same ones on my ASMedia USB 3.1 eXtensible Host Controller and also couldn't recognize the Pixel C any longer. I rolled back to ASMedia drivers, it worked fine. Updated using newer ASMedia drivers 4/11/2016 ver 1.16.35.1 and those work fine. Now to find working drivers for the Inter Host. Win7 drivers refuse to load.
UPDATE: If your bios allows, disable xHCI. Your USB ports will work as USB 2.0 but will detect your PIXEL C without issues.
Solution works 100%
If you've installed the SDK drivers and win10 can detect your Pixel C in every mode with usb debugging off. Use these win10 USB xHCi drivers,

You need to do it manually. Google "how to manually update drivers windows 10". Do it via device manager with your Pixel C plugged in.
did do. And also before have tried to "point the update to" sdk and Wug's folders. Am not a total noob, but braincells do die, I cant stop it! If it matters, I did just few days ago clean-"re"install win10 64 but this problem was b4 that.. hence the clean start over. All Im ever getting is MTP USB Device, or wen tab's in fastboot, Android ADB Device. Both say "best is already installed".
also have done the "disable driver enforce", i do that routinely now til this is solved..

Unlock bootloader - "waiting for any device"

I got my OP3 today and am trying to unlock the bootloader. I've tried every tutorial and toolkit out there but they all get stuck at the same point in adb, "waiting for device". The "adb devices" command works fine but anything else gets stuck on "waiting for any device". I've tried googling the issue but none of the suggestions have worked so far. Any input would be great.
did you enable oem unlocking from developer options?
bro you may be running win 10 and to connect fastboot on that u need adb driver which u will find on windows update all u have to do is just connect your phone with data transfer mode and update the window 10 . ull find something name qalllcom its adb drive or i dont but after that it will like charm.
I have all the necessary developer options checked. After futzing with it for hours, I tried a different computer (also Windows 10) and it worked right away. I'm going to see what the driver issue is this evening because I still would like to use the original computer I was using. Thanks for the replies!

I've tried everything including disabling driver enforcement on Win 10 but I still have the same issue. I have the wrong drivers installed. I've tried uninstalling and reinstalling the drivers but when I plugin the phone, the wrong drivers get installed. I got it to work on another Windows 10 computer and below are device manager screenshots of the working (with right drivers) and not working (with wrong drivers) computers. I have no idea how to get the right drivers installed on the computer where its not working and unfortunately, its the primary computer I use.

Try this:
Connect the op3 to usb port - don't bother changing from "charging"
Right click on "ADB Interface" in dev man and disable it.
Without unplugging the op3 use the buttons to reboot into bootloader.
Hopefully W10 will now detect your op3 and either load the correct "oneplus" driver or create a new entry in dev man of Other Devices > Android Composite ADB Interface. Right click on this and then Update driver software > Browse my computer.... > Let me pick... > and if you're lucky One plus will show up in the manufacturer column and allow you to select the composite interface

Okay so this is the problem. I figured it out 2 days ago.
check the bootloader driver when you're in fastboot. Right click it and update driver, it should be the Android Bootloader 9.00, and not Bootloader 11.00
it's a silly weird fix, but it should be under Android and not Kedacom
I was using the Android SDK Studio Platform Tools and Google Drivers provided from SDK Studio
deleted
Similiar to the previous users post I'll try and be a bit more clear.
unplug your device if plugged in.
boot in to fastboot mode on your device.
Go to your PC and access device manager
plug your device in and you should see
"kedacom" instead of android interface
now inside you wanna click update driver
browse my compute for driver software > let me pick from a list of driver software > "Android adb sooner interface"
if its not that exact one check for the one that does say adb interface.

I created a bootable USB drive with Linux Mint to solve my problem. It was Windows 10 that would recognize my OnePlus 3 in "Fastboot Mode" with Kedacom drivers.

OP3 Not Found By Fastboot (Win 10)

So I'm running windows 10 on my pc and my op3 is easily found by windows. When I enter fastboot mode on my op3, the command "fastboot devices" doesn't show my op3. I used that 15 sec adb & fastboot installer.

Have you enabled oem unlocking from developer options?
I'm having the same problem. After going back to Oxygen OS (now 3.5.4) from MIUI 8 fastboot just doesn't work anymore. ABD works just fine (tried on Minimal ABD and Fastboot on Windows and ABD installed over Android Studio on Ubuntu. Fastboot did recognize the phone on Ubuntu but flashing TWRP resolved in a bootloop (tried the old and the new recovery image).
All drivers are installed on both Windows and Ubuntu (I even removed all drivers on Windows and added them again) and just to make sure everything gets installed I disabled driver signature verification on Windows, but as I said - still no luck.
Edit: Of course USB Debugging and OEM Unlocking is enabled (my bootloader is also unlocked since I already had tried out multiple roms)
Had the same Problem, Win10 is the Problem + the old OP Drivers + the new Update to Win10 etc.
Nothing worked, tryed everything. Created a Thread last week here also...
After that i created a new Partition and installed Win7 on it. All works fine, only thing is while Boot ur System u have to pick ur OS or it waits 30sec to boot up but thats ok.
Now i have Win10 for everything and i reboot to win7 for Fastboot/OP3

Can't solve your problem, but OP3 fastboot does work in Windows 10. I did have to disable driver signature verification to install the driver in the first place, and you'll have to leave it off for the driver to stay functional, but it definitely works on Win 10.
I dont tryed ur Way, so yes after disable Driver sign. it works like u Said but i did not Test it.
i had the same problem to find the correct adb driver spent many hours but it didnt work so after that last i try to update windows 10 and find adb driver there after updating window its work like charm so all u have to do is just connect ur phone with data transfer mode on and search the window automatic updates .
Same here
It's driving me crazy. I've updated from a rooted stock OS (incl TWRP) via full OTA directly to 3.2.7, which removed TWRP and root.
I now cannot enter a Fastboot mode which detects the USB connection. Thus I can't flash TWRP again and can't root my phone, making lots of apps unusable.
I've tried every suggestion on every thread but nothing works...

Also got kedacom on my device manager after automatic driver update but my phone still isn't recognised in adb devices, does everyone else's serial number show up?
You guys still have the problem?

Managed to solve it: Disable driver signature verification (follow howtogeek guide) then reinstall Drivers from Oneplus. Go to device manager chose the Kedacom Device and select the correct Oneplus Driver instead then reboot PC and Phone and now it should work

Well I didn't really solve the problem on win 10 so i just decided to use Ubuntu instead. Worked well

I tried that too, but didn't work. What driver did you select in Device manager?

Rebooted both devices, OP3 was in fastboot. Then there was a Driver called Oneplus Bootloader Interface (or something similar)

The driver that shows up as a spare drive when you connect the phone? Tried that too, no good. Going to boot Ubuntu later today, hope that works. I just need twrp, then I'm good ?

Yeah that one. After disabling the driver signature verification you have to re install it, when it's not disabled windows just doesn't install it although it says it does. After I disabled it Windows actually showed a completely new window during installation to install the driver properly
