On Device Manager (Window 10). Were updating the driver, I can only see ADB interface but no Fastboot interface. I'm on the latest version SDK from Google and have OnePlus driver installed. I can command ADB but not fastboot. What am I missing? My device is OnePlus 7T TMobile is sim unlocked and I can toggle OEM unlocking and is on.
Not sure what mean, but fastboot only works when you're booted in bootloader. (Adb reboot bootloader)

That's correct but when I fastboot cmd it get stuck on "waiting for device". So I read around on XDA on how to fix it and I tried to follow the instruction on PC - device manager, still no go.

I myself have never had this problem, I can only suggestion reinstalling OnePlus drivers.
Hopefully you figure this out

I reinstalled couple of times. Still no go! This is the first time that this happening. Never had problem since day one on Nexus devices. I'm going to try again and search more around.
You can also use the universal drivers by clockworkmod https://adb.clockworkmod.com/
Here's what I did.
1) Extract the android sdk platform tools and put on your c:// drive
2) Install the universal usb drivers
3) Enable usb debugging on your one plus and connect to computer. Switch to usb debugging mode and accept the popup on your one plus to allow the connection.
4) Open cmd and run "cd C:\platform-tools", then run "adb devices" to ensure that your devices is connected properly
5) Run "reboot bootloader" and device will restart into bootloader mode and fastboot will now work
*This is all assuming that you've already oem unlocked your devices as well already*
It work till fastboot. Still stuck at "waiting for device".

Are you trying to open? Command shell? In windows 10 right? So for your information in windows 10 it's not supported , you have to open that platform tool folder which you installed already named as adb, platform tools , sdk may go into that folder and you will see a folders directory above there .. just click on that and type cmd and hit enter and cmd will pop up now you can use all your commands it's not your fault it's windows 10 fault ..maybe hope it may work for you
That how I done it. Fastboot Command appear on my Google Pixel 2 and 3 but I can't do it on my 7T. I don't get it
Thanks for the help! I tried working on Device Manager on PC yet doesn't work. Adb shell command work but no Fastboot command.
I found the solution! This is what I did and it worked for me! Here's the link for anyone who has the same issue I went through. Here you go and follow the instruction. http://www.wtfandroid.com/fix-fastboot-device-not-recognised-problem/
Mod you can close this thread. Thanks again for everyone who tried to help me. :highfive:

Hey everyone,
Alright so I have been trying to root my phone for the past 4 hours. I have unlocked it and flashed a custom recovery using adb. Or at least I thought I did. I tried flashing the clockworks recovery and when I would reboot it into the recovery, I would get an icon of a phone and an exclimation point. I assumed a bricked the phone and freaked out. A minute later the phone rebooted out of recovery and works fine afterwards. So I assume that the problem is the recovery. Something went wrong and I am not sure what.
Here are the steps I followed:
I was fine up until step four when I was trying to flash superuser.
No idea what to do from here.
HTC Unlocked = Bootloader is unlocked?
Not to take away from the OP, but i created a guide for a guy here at work and thought others might benefit from it.
Unlock Bootloader and Root
Unlocking your bootloader will wipe all data from your phone. Meaning you will loose everything make a backup.
Step 1: ADB Installation Instructions. NOTE:You must have ADB installed on your PC even if you use method 2b to unlock the bootloader. You will need adb to install recovery in Step 4.
1. Go to http://developer.android.com/sdk/index.html and download the sdk.
2. Follow installation instructions found here. Note: This is not a forum for this device DO NOT do anything but the adb installation on your system.
Step 2a: Download software from HTC to allow your bootloader to be unlocked.
1. Go to http://www.htcdev.com/
2. Login to the website. NOTE: Register for an account if you haven’t already. You must provide a valid email address.
3. Select “All Other Supported Models” from the drop down list and click “Begin Unlock Bootloader”
4. Follow online instructions.
1. SuperUser http://androidfiles.org/securekey.ph.../superuser.zip - Copy this file you phone. Special thanks to jmztaylor his link.
2. Recovery of your choice TWRP Recovery http://forum.xda-developers.com/show....php?t=2161702 or CWM Recovery http://forum.xda-developers.com/show....php?t=2161706. Put this file in the ADB Tools folder. NOTE: You must type the name of this file perfectly when using adb to flash it in step 4.
Step 4: Using ADB to install recovery
1. Open command prompt ( shift + right click, then choose “Open command window here”) and type “ADB devices” you should see you phone listed, if you do not start over at Step 1. NOTE: Phone must be plugged in and USB Debugging must be checked in settings.
2. Type “ADB flash recovery recovery.img” without the quotes. NOTE: the red is actually the title of the recovery file that you copied in step 3. If it’s different substitute your files name instead.
3. Once complete type “ABD reboot recovery”.
4. You should at this point backup your device
5. Once you create a backup, Choose install and navigate to the SuperUser file you put on your phone in Step 3.
6. If all goes well you are now rooted. Select reboot system to restart phone.
There is some very good information here but its spread out pretty thin. Guides IMHO are very usefull to fill the gap between devs/powerusers and the newbs.Most people that come here have a hard time with the things we take for granted such as adb commands, or adb its self (most will be setting it up for the first time). I tried my best to put it in a knowledge base that everyone can understand if for some reason you do not understand what i was trying to say please ask. I don't own this phone, just helped a friend root his, but if you need to get ahold of me pm me. I'll get back to you as soon as possible.
Any help? Just trying to get rid of the bloatware -_-
Did you copy superuser to your phone? And are you sure you are using the correct file location for adb in the command prompt? You must make sure you are and that all files you want to flash are also in the same folder as adb. Please respond if you have superuser on your phone and if you are positive you are using the correct adb folder location for the command prompt. I'm not the best at this however, I read up a lot on it just to root my phone. Took me 4 hours about as well, but that was before the recoverys came out. I suggest trying to flash twrp recovery, it's a bit buggy (for me) but I find it easier to use.

Code:
ADB flash recovery recovery.img
that is your problem to start with its not "ADB flash"
boot your phone into bootloader with usb connected to PC, Phone should read "fastboot"
Go the your adb directory in command prompt.
ex.
Code:
C:\PcUser\Master\Androidsdk\adb\
Make sure all drivers are installed, from CMD prompt window type "fastboot devices" to check your phone is showing.
if you see your device then you can type
fastboot flash recovery [drag your recovery image into cmd window] and hit enter and it should flash
once recovery is flashed you can either "fastboot Reboot" or on the phone use the Vol rockers to navigate to menu and hit bootloader then from there choose recovery
Hi,
I have the same issue about 2 days, I install TWRP Recovery and all it's ok, and flash in fastboot mode with adb like ilostchild tolds You.
It seems that I met the same problem.
My issue is the phone only boot into CMW mode, although I tried to restart it many times. When connect to usb cable, lappy did not recognize the phone so I can use adb command.
Please help me.
I can't make ADB recognize the device, I already installed the SDK the HTC Sync program but the device appears either as "My HTC" or "Android 1.0" and won't appear under "adb devices", any help? I have been googling for 3 days for a solution but I haven't found anything so far.

Try using another computer!!! Install all neded drivers, searxh google and let windows automaticly install some. Connect via fastboot and it should say
Fastboot usb.
Also....dont search for adb devices, just enter commands starting with fastboot like... Fastboot install recovery cwmrecovery.img

Uninstall HTC sync then try adb devices be possitive you are using the correct location for adb. Usb debugging MUST be on as well. Copy paste the commands into the prompt to make sure you are entering them right. Be sure you have the downloaded files in the same folder you are using with adb.

Already tried uninstalling HTC Sync, after that I deleted every trace of it. USB Debugging WAS ON before the phone crashed but I can't activate it now because the phone keeps looping between reboots.
Try to flash it via htc sync. Download the update and rewrite everything!

Ok, I *have* searched the forums and googled this, but none of the standard solutions seem to work.
I have the Verizon HTC One and successfully ran the rumrunner S-OFF (root, unlocked, etc). Now I want to flash a recovery using fastboot, but no matter what I do, I cannot get "fastboot devices" to show anything (or I get <waiting for device> if I try anything else with fastboot). ADB works fine.
On Ubuntu 11.10:
I downloaded the back-ported android-tools (apt-get install android-tools-fastboot/adb from the ppa:nilarimogard/webupd8 repository).
I tried fastboot as root, and I also tried with a udev rule (SUBSYSTEMS=="usb", ATTRS{idVendor}=="0bb4", MODE="0666").
adb works fine (I used it to reboot in fastboot-usb mode)
I tried different USB ports.
On Windows 7:
I tried both fastboot from the Android SDK and from the "Minimal Tools".
ADB works fine.
I un-installed and re-installed drivers as I plugged in and unplugged my phone into the USB ports.
Note that Windows 7 does complain about the drivers and says that the device is unplugged when it isn't. It seems to timeout when trying to install drivers from the internet
I tried installing and uninstalling HTC Sync, PDANet.
I would prefer if there is a way to make it work in Ubuntu so that I can eliminate the Windows drivers from the equation. Anything obvious that I missed? Does the version of fastboot matter?
Thanks in advance for any suggestions.

Do you have Fastboot turned off in system settings?
Unless I'm mistaken, you need to be sure that's switched off to utilize fastboot mode.
If it's already switched off and you are still having the issue, then ignore this post.

I have fastboot checked in settings and fastboot commands work... When I'm in fastboot mode.
OP, I have made the simple mistake of not putting it in fastboot mode before. Were you booted into fastboot mode? I.E. reboot into bootloader, with fastboot selected hit the power button and ensure that it says deadbolt at the top? Something really simple that had tripped me up before!

This is worth a shot, as I've read in previous post. Only plug your HTC One into a usb 2.0 instead of 3.0. What does this mean? If you look inside the usb on your computer and the color you see is blue? Don't use that one. For whatever reason, when using the commands, usb 3.0 doesn't work with the HTC One. If you only have the 3.0 ports... I have nothing.

ADB works fine over USB 3.0 for any Android device if you have the proper drivers installed. If you have a mixture of 2.0 and 3.0 ports, as I do, use the 2.0, as it is more reliable, though slower. I'm using ADB on my device via USB 3.0 as I type this, using Windows 7 x64.
If your motherboard has an Intel chipset, you can try this method to get Fastboot working over USB 3.0, just disregard the download links about making it work on Windows 8, as the drivers were designed for Windows 7. My motherboard has an Asmedia USB 3.0 controller, and I am unable to use the Intel drivers, and thus unable to use Fastboot over USB 3.0, which isn't really a problem for me, as I also have the USB 2.0 ports.

So just to be patently clear. To boot into fastboot, I reboot into the bootloader with USB attached, select "fastboot", then it says "fastboot USB" and I select "Reboot", correct? I have never noticed the word "deadbolt". Is there a way to check on the phone that I've booted into fastboot?
I have been using USB 2 ports (tried different ones).
I have fast boot unchecked in my settings.

Don't click reboot once your phone says "Fastboot USB". That's where you're going wrong.
You say that ADB works on occasion. Trying downloading the newest drivers from this thread. Plug your phone in and type "adb devices". If it displays your phone's serial number and says "device" next to it, you're doing fine. Then type "adb reboot bootloader". It will bring you to where you are able to type fastboot commands. Type "fastboot devices". If it shows your device's serial number and says "fastboot" next to it, then your Fastboot commands will work properly.

Open a terminal emulator on your phone then get root access:
su
After that, cd to the location of the .img file: (i.e. if it was on the root of the sd card then...)
cd /sdcard/
Finally, flash the image to the recovery partition:
dd if=recovery.img of=/dev/block/mmcblk0p21 (not sure if this location will be different on this phone..someone else may want to chime in)
Then exit the terminal emulator and reboot.

Thanks, not clicking the reboot made it work with fastboot (even in Win7!). I was confused by the statements about rebooting "into fastboot" and assuming that once it displayed "fastboot USB" I should reboot. Took me 2 seconds to install TWRP once this PEBKAC was resolved .
I would've tried the dd option from the terminal, but I'm glad I didn't have to (have used that wrong once on a Linux system and it was not pleasant!).
Glad you figured it out, even with my typo!

Hi, I have been trying to debrick my tp and I've posted in forums asking basically this question.. seems it goes fine till failed to install/find Fastboot.. would you send me the command? thanks..
Dear all,
I have worked on building Android from source code for few weeks. It used to be fine to me with my galaxy nexus, I can connect to my device via adb and fastboot and flash either the factory ROM or ROM built by me into my device. However, when updating the phone into 4.3, I forgot to extract drivers into the built directory and flash the built image into my device. Is surely can't work, and the screen turn off once "Google" is shown, so I would like to reflash it back to other image. However, my laptop can't recognize my Nexus S anymore in the bootloader. I can use "adb shell" once the device is normally booted (even without screen), but once I type "adb reboot bootloader", the connection is lost! Both "adb and fastboot devices" show nothing....
I have searched the forum and stackoverflow all day but can't find helpful information. There are many threads talking about unable to connect devices but 70% of them are driver-related issue and 30% of them, ex: sudo adb, just don't work for me. I think I am not facing the driver issue because I still can use "adb shell" once the device is normally booted (not in bootloader mode). Moreover, I also tried few debrick tools contributed by xda community but with no luck.
I am wondering if there is any way that I can reflash image to my device without accessing it in bootloader mode? (ex: push image in to device via adb shell when device is normally booted?). I am also wondering if there is any way to fix this problem. Any suggestion is very appreciated!: crying:
Thanks

ps. the most closed thread I found is called "ADB can discover devices but not fastboot" in stackexchange (I am not allowed to post the link)
but it seems there is no answer in this thread
I'm not a expert, but do you know how is the DD command ?,
I wonder, is you can DD the boot loader into the nexus partition?

Thanks for the reply. I am not sure what I should do with dd command? Could I use it to reinstall the drivers into device?
by the way, I found there is a error showing up in the bottom of screen in fastboot mode, "Fastboot Command Read Error -2147483647", and many closed threads (sorry that I am not allowed to post url because I am new). Some suggests are to reinstall drivers (even thought I don't get if they mean reinstall the usb driver for laptop or for android), but it seems not solved yet.

Dear all, I think I have tried all potential solution about "fastboot command read error -2147483647" that I can find at internet......
Here is what solution I have tried:
1. sudo the command of adb and fastboot
2. update drivers
3. update sdk
4. use another cable
5. install other drivers (win7), ex: naked driver
6. Wug's root kit
What I can't try:
1. enable USB debug mode at phone (because I don't have screen of it but only adb shell)
2. remove(uninstall) other software such as PDA net...etc (I don't try this because my system is clean-installed win7/MAC/ubuntu)
I think this problem is kind of common but my situation seems slightly different from others, that I can find the device when my device is normally booted but I can't recognize it when it is rebooted into bootloader (showing "fastboot command read error -2147483647" at bottom). I am starting to believe it either be the problem that I don't activate the USB debugging in my new flashed image (but I can connect it with adb when the device is normalled booted) or the usb driver in my device is broken.
Anyone has any idea.....:crying:

Dear all,
This is my latest update. I wipe out the whole system of Ubuntu and Win7 and restart everything from the first step. Magically, the new Win7 + Wug's root kit can successfully flash new image into my phone. But also magically, the ubuntu system faces the same issue as I described (no connection in bootloader with the error code but connection is fine after the device is booted). The bright side of this is that I am finally able to try other solutions, e.g., enabling debugging mode, but the sad part is that I still get no luck at Ubuntu and MAC.........can't believe it works at Win7 but not at Ubuntu and MAC.....

I've installed ADB/Fastboot/USB Drivers from http://forum.xda-developers.com/showthread.php?t=2588979 (tried both 1.3 and 1.4.2 versions.
Booted my SW3 into Fastboot (whitescreen, with fastboot written on it) - attached to the PC, Device shows up as SAMSUNG Android Phone > Android ADB Interface
Ran CMD as an Administrator.
Typed, adb reboot bootloader.... Error: device '<null>' not found.
Typed adb devices... not listed.
Okay, so using a driver stripper (and windows program uninstaller), removed all Samsung phone USB drivers, KIES and existing ADB drivers. Re-ran the top tool to re-install everything. Repeated process, still showing up as SAMSUNG Android Phone > Android ADB Interface. Still not detected.
No idea at all what's going on here. I've tried cleaning the drivers multiple times. Other USB ports (2.0 & 3.0). Tried manually updating the driver to Google Inc. driver variants (9.0-11.0)
Really appreciate any help here.

Mind if I pick your brain on that point. I'm used to ADB on a smartphone, I really expected this to be similar but there's clearly some catches.
I don't think I'm into bootloader yet because the command 'adb reboot bootloader, or adb reboot-bootloader' doesn't do anything other than throw the error mentioned above.
However, typing fastboot devices gives me.

But this doesn't allow me to process to run through the other ADB commands I need to complete. 'adb devices' still lists nothing.
In short, I'm trying to downgrade my SW3 to LCA32, as required to turn on the NFC functionality https://github.com/pimpimmi/LibreAlarm/wiki/How-to-install-NFC-on-Sony-Smartwatch-3
It's to assist in enhancing a medical device that uses NFC.

Okay progress, I see what you mean now adb reboot bootloader doesn't work. But fastboot reboot bootloader does. This is allowing me to move through the necessary TWRP and img steps. Thanks.
so I'm trying to fastboot flash TWRP. That way I can root it after the custom recovery is set up.
My HTC is S-OFF, I installed android studio for the adb fastboot command prompt. Then installed all HTC drivers. I then plugged in my HTC into my pc which is running windows 10 via USB port which are 3.0
I opened up the folder where the fastboot was installed when I downloaded android studio. Then I pushed shift and right clicked and chose open command promp. I then typed: adb devices
The command prompt runs and it shows my HTC in the device list. Then I typed: adb reboot bootloader. It boots to the fastboot.
And so here is my problem........... once I boots to fastboot I thenjoy again type: adb devices. Cmd runs and the device list is blank. I checked my drivers and device in device manager and everything is fine. Even I'm fastboot it reads the drivers no problem.
I've tried everything. I've read to try reinstalling the drivers, try installing universal drivers, try different USB cables, try different USB ports that arent 3.0 port, I even tried a different adb fastboot software and still came up with the same outcome. I've read a bunch of different threads and just can't find anything. I am just stuck I don't know what to do. And am asking for help please. I would really appreciate the help and guidance. Because....... this s**t is driving me crazy haha. I've rooted galaxies and have my s5 on lollipop rooted. But
I'm still a noob and especially with HTC. So please some one lend me a helping head I am at a complete loss.

so I'm trying to fastboot flash TWRP. That way I can root it after the custom recovery is set up.
My HTC is S-OFF, I installed android studio for the adb fastboot command prompt. Then installed all HTC drivers. I then plugged in my HTC into my pc which is running windows 10 via USB port which are 3.0

You're using the wrong command.
You can't use adb commands when booted to bootloader, only while booted to system, as you did the first time.
Once you do adb reboot bootloader use fastboot devices and your phone will show in cmd. You need to use fastboot commands while booted to bootloader.

Wow that was so simple...... (face palm)
You are a saint haha. Thank you very much that was getting to me. It did show up was able to flash twrp.
No where did I see anything about typing fastboot in cmd instead of adb while phone was in fastboot. Well it might of and I might of just not of understood it when I read it. Again thank you I appreciate it
