Hey, I am having trouble pushing TWRP onto my op3 via fastboot. I managed to unlock my bootloader successfully but after that, I know cannot flash TWRP. When I type in "adb devices" It returns a string, however "fastboot devices" does nothing. I've uninstalled and re-installed oneplus usb, fastboot and adb drivers countless time and even reset my PC twice. Any ideas? This is really frustrating as I was on TWRP fine before I had to RMA my op3 where they put it back to stock. Any ideas? Thanks

But phone starts ok in OOS system?
If, yes, download TWRP 3.0.2.1 original & TWRP 3.0.2.1-19 modified. Put them in phone sd card. Download FLashify from Play store and flash recovery .img. Then go recovery to test if it works.
One of those will work.

Got the same problem too, after unlocking the bootloader the fastboot devices cannot find anything :rolleyes:
Tested several drivers and even another laptop :/

Rom: OOS 3.2.7
PC: Windows 10

Yeah me too, same ROM and PC OS. Very strange

I've solved that problem by installing Windows 7 on a Virtual Machine the phone Was recognized and has installed the drivers by itself. And fastboot was working :D
I don't know why fastboot is not working on Windows 10....

Had the same issue, here's what fixed it for me:
(On Windows 10)
1 - Plug your device while on and install the OP3 drivers that appear as a removable disk, I reinstalled them also, so no harm in doing that again.
2 - Run admin command prompt from wherever you have your adb and fastboot
3 - get your device into fastboot/bootloader mode "adb reboot bootloader"
4 - press windows key + X and go to device manager, look for the Android device with exclamation mark
5 - right click on Android Device > update driver software > browse my computer... > let me pick... > look for Android and then select Android Fastboot Interface if memory serves me right.

And that's it. Fastboot should be recognized now. That's what worked for me when windows recognized adb but not fastboot, hope it helps out.

I'm sorry to hear it didn't work, I'd try to reinstall adb and fastboot then using Minimal Adb and Fastboot found in this thread http://forum.xda-developers.com/showthread.php?t=2317790

I have the same issue. Got my OP3 yesterday and have been trying in vain to get my Windows 10 install to recognise the phone in fastboot mode, but to no avail. I am unable to unlock my bootloader. :(

Got some news for you:
I was so frustrated that I decided to install Windows 7 over my Windows 10 and have a try.
Well what should I say: everything worked on the first try, without any problems with the original driver which comes with the op3 when you plugin the phone.
Hope I could help ;)

It appears to be an issue with Windows 10 drivers. I have used an ancient install of Xubuntu on an older EeePC in order to unlock the bootloader and flash TWRP and SuperSU. I've still had no luck getting fastboot to be recognised on Windows 10, though on Xubuntu, it is recognised instantly with no issues.

I'm not at my pc atm but I'll try my best:
If you plugin your op3 there will be a cd mounted with the setup for the driver.
I just installed this driver with the setup.exe (on a complete new instance of Windows 7).
After the installer was finished, I opened cmd.exe and could use adb and fastboot.

    I think you might find something is showing but it isn't broken out with an exclamation. I don't remember what mine was called when in bootloader but it wasn't obvious, it was in one of the bottom couple of sections. I want to say usb devices but don't recall. I found it be plugging my phone in and out over and over while checking each section for a device coming and going. It could not be seen at opening tree and nothing changed there when plugging and unplugging.

    I had this exact issue and fixed it.

    Fastboot would never see my device, no matter which driver package I tried or no matter how I tried to install or force the correct drivers. Turns out Windows 10 (and Windows 8) has a feature that completely prevents installation of unsigned drivers, which blocks the fastboot driver. If you're seeing "Kedracom" or "Android Device" in the device manager, then your driver is NOT actually installed. This is true even if Windows doesn't throw you an error message during install, or if you appear to force the installation. Even though it looks like you're doing the install correctly, Windows just ignores your unsigned drivers.

    You need to temporarily disable the security feature to permit installation of unsigned drivers. This involves invoking a special restart function. Here's the howto for Win10: http://www.howtogeek.com/167723/how-...igned-drivers/

    Once you've done this you, you can do a forced install of the drivers you downloaded for the OP3.

    I'm running Win10 Pro x64 Anniversary Update, this is how I fixed it:

    -I uninstalled all existing ADB drivers I had
    -I disabled driver signature verification (start, change advanced startup option, (Under Advanced startup) press Restart, Troubleshoot, Advanced Options, Startup Settings, press Restart, select 7) Disable driver signature enforcement, reboot)
    -I installed the OnePlus USB drivers
    -When in fastboot mode in Device Manager, "Kedacom USB Device -> Android bootloader interface" shows
    -Right click, Update Driver Software, Browse my computer...,"Let me pick from a list....", Choose OnePlus Android Bootloader Interface, Next.
