[Q] Cannot Unlock Bootloader on Windows 8.1

Hello,
I cannot get the bootloader unlock working on my Win 8.1 laptop by any means. If I try through hasoon2000's toolkit, I get the error that the ADB server did not ACK (whatever that means). If I try using the command line and HTC's official method of getting the TokenID, I get a message that a certain ADB-related dll is not installed. I have installed the USB drivers that come with hasoon2000's toolkit about 4 times now. I installed the Android SDK and even Samsung USB drivers. I'm going to uninstall everything, can someone walk me through the step-by-step to get things working? I've read that USB 3.0 is the problem, but I only have USB 3.0 ports on my laptop.

Use another computer if you can.

I had similar problems until I used this version of adb

Run everything from the downloaded folder.
First of all ensure you have USB DEBUGGING enabled in DEVELOPER OPTIONS in the phone settings.
Open the downloaded folder then right click inside the folder while holding shift then choose 'Open command Windows here'
Plug in the phone using the original HTC usb cable then in the command window type ADB DEVICES. The response should be a device comprised of letters and numbers.
If you don't see any device attached try swapping the cable to another usb port. If you see your device attached then follow the unlock instructions at HTCDEV as its the most reliable way.
If still no device then it could be a usb driver problem. You should here a ding when you plug your phone in.
Make sure the Unlock_code.bin is in the above folder when unlocking.

That version of ADB didn't work for me either. Anyway I was able to get fastboot to work but not ADB so I was able to unlock and root and everything through a strange method using only fastboot.
Second question, if I am switching between AOSP roms, say for example CM to PA, can I dirty flash or do I have to reset?

ADB does not work with USB 3.0 ports yet on Windows 8 or 8.1. You have to use it on a USB 2.0 port. I have had best results with Windows 7. Fastboot, however, works just fine on 8.1 and 8

Not so, I and others have ADB working fine on USB 3.0 ports.
The problem is Windows 8 driver signing enforcement blocking the install of drivers. You need to go to advanced startup options to disable it.
Download these drivers first and extract: http://www.mediafire.com/download/i3lcm7dwl581518/ADB_Fastboot_Drivers_Win81.zip
Follow these instructions to disable driver signing enforcement: http://www.isunshare.com/windows-8/...gnature-enforcement-in-windows-8-and-8.1.html
Once fully booted go into device manager and you should see a device called 'Android 1.0' with an exclamation mark.
Right click 'Android 1.0' then 'update driver software' then 'Browse my computer for driver software'
Click the 'Browse' button and then browse to the driver folder 'ADB_Fastboot_Drivers_Win81' extracted earlier then click next to install the driver.
You will get a warning about unsigned drivers, just ignore and continue.
The drivers should install and you should see a new entry in device manager called 'Android phone' which means the ADB driver is installed.
ADB should now be working.

Thank you so much for this. Have been wondering for a very long time

It sounds like you've got plenty of technical help already, but I will say that I use ADB perfectly fine on my desktop with Win 8.1 so it's possible. I also use hassoon's toolkit occasionally with no issue.
Before I could get the desktop to recognize the M8 I had to completely uninstall all drivers related to my previous galaxy nexus as well as remove any mention of the device in Window's USBdeview. After a reboot, I just plugged in the M8 and windows automatically installed the necessary M8 drivers. I can then run fastboot and adb from the toolkit.

I ended up uninstalling the MSFT USB 3.0 drivers and use the Intel USB 3.0 drivers instead on my Win8.1 laptop that has only USB 3.0 ports. Works great.

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!

What does "adb devices" return?

Screenshot:

for bl unlock, you need to be at fastboot mode, and installed right driver, for me working any of stock Google USB package fastboot bootloader driver.

Go to fastboot mode and do "fastboot devices", then try unlocking bl.

You can install the driver after disabling the driver enforcement..

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.

Same here. When I reboot in fastboot mode, the driver adb interface disappears and I get the Android Bootloader Interface (Kedacom USB Driver).
"waiting for any device" each time.
Thx for help

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

I tried this but didn't see any new/different entry in DM when I rebooted into bootloader. Didn't see OnePlus under manufacturers either.

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

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.

Windows 10 and fastboot driver | Nexus 5X

I can not use fastboot on my pc with Windows 10 to flash something on my Nexus 5X.
I've installed Ubuntu and adb/fastbook works correctly. With Ubuntu I've installed TWRP and SuperSU.
On Windows 10:
- Adb works.
- I've Android Studio with the latest platform-tools.
- I've tried with 15 seconds ADB Installer v1.4.3.
- I've tried with this answer.
- I've already removed all usb-driver (as Nexus Root Toolkit suggest) and retry all.
What can I do?

Let windows download the fastboot drivers from the network.
boot into fastboot, connect to pc
open up
win-r
devmgmt.msc
right click the 5x device and search network for drivers (or wherever that option is)
It'll come it with something like marshall london bootloader interface. That is fine, it works, it is for different phone that is also android based. The bootloader interface is the same.

I had the very same problem when I first received my 5X. I tried every damn think on to get Windows 10 to see the device, including all listed here and manually installing the drivers downloaded from Google and various other sites. Installed various Windows 10 packages. Even LG driver packages. I believe the issue lies in Windows 10 and I think perhaps maybe compounded by other drivers installed on the computer. I'm willing to bet it would work just fine on 7 (did on every machine I tried). Eventually adb and fastboot magically started working but I still could not use MTP. The ONLY thing that got it working was, strangely enough, a reinstall of Windows 10 (chose to kept files/documents) and then updating with the Anniversary Update). I know that is like the LEAST desirable option.
Windows 10 is really just not great for this sort of thing.

I don't know if google fixed it, but the 11.0 Google USB drivers don't have the fastboot USB IDs for the 5x but most people wouldn't notice because win10 is probably configured to get drivers automatically from net.
I noticed because I don't have that enabled.
On a win10 box that is configured to get drivers from net, for 5x, adb, mtp, and fastboot work without installing any extra drivers.

Yeah, that's exactly how it's worked every other android device I've owned too-only had issues with this device and this particular Windows 10 machine. This machine is configured to get drivers automatically, but for whatever reason I just couldn't get this to work. Of course, this was just my experience but there have defintiely been other folks out there with similar (maybe not exactly the same) problems. It was infuriating!
I can't really comment intelligently regarding what Google may have done to fix this. I'm shaking my head to hear that their drivers for Nexus devices is missing the fastboot USB ID's for a Nexus phone lol

Can't use ADB

So I uninstalled all of the previous Samsung/Koush/Intel Android USB drivers for and downloaded SDK Google USB driver. But I can't get adb to work - when I connect the phone, it says Pixel XL under Portable Devices in Device Manager (Win 7.) I can transfer files, but ADB just won't work.
I used some Intel and Koush Android ADB Device drivers previously, and the Google Nexus ADB device did appear in Device Manager, but adb was still a no go.
Does anyone know how to fix this?
Thanks.

Just to make sure, you did enable adb debugging in developer options, right? When you connect the phone to your computer, are you choosing the transfer files option? What is showing up in device manager?

I enabled debugging in developers options.
I tried most of the settings - charging, file transfer, ptp.
When I connect the phone, only one thing appears - Pixel XL under Portable Devices.
I can transfer files as mtp and ptp.
I can also update the driver for Pixel XL and force Google Nexus ADB driver (I believe it comes from something like 2013-2014 USB driver package by Koush.) When I do that, Pixel XL disappears and Android ADB device replaces it under Android Devices. But ADB still doesn't work, when I do adb devices - nothing shows up.
I can also update this driver with a current Google USB driver from the latest android SDK. I think it's version 11. When I do this, Android ADB device gets replaced with Pixel XL under Portable Devices. Still no adb.
I have updated Java SDK, I have updated Windows 7. I spent literally 4-5 hours on this, and I can't figure it out.

When you see it as adb under device manager, try removing the driver by right clicking and uninstall. Unplug the device and replug it in. Then make sure it's using the newest SDK driver, that's what worked for me.

Tried a different computer. Adb worked as soon as I installed the 15 seconds adb installer.
There's something wrong with my main computer. I already tried uninstalling and reinstalling the driver - it just doesn't work - every time the device is recognized as mtp usb device.

Any tips would be greatly appreciated!

You could try using the adb minimal with fastboot at the xda link below. It was updated on 10-22-16 this is what I use.

If it's an OP 3 then why are you using Samsung drivers? You need OnePlus drivers, obviously. I always followed this guide (exactly like it says) and never had an issue with my drivers so far.
This is from an OP 8 group, but the drivers should be the same:
To install the drivers, ensure that driver signature verification is disabled. Instructions:
How to Disable Driver Signature Verification on 64-Bit Windows 8 or 10 (So That You Can Install Unsigned Drivers)
64-bit versions of Windows 10 and 8 include a “driver signature enforcement” feature. They’ll only load drivers that have been signed by Microsoft. To install less-than-official drivers, old unsigned drivers, or drivers you’re developing yourself, you’ll need to disable driver signature enforcement.
