Soft brick, but can't even get drivers to install - Nexus 6P Q&A, Help & Troubleshooting

I was trying to install the October security updates on my rooted 6P and thought I did so successfully. However, when it rebooted, it just hung on the Google screen for an hour and I tried to investigate. It appears that I no longer have a recovery or OS and that all I can do is go into the bootloader and reboot the bootloader.
I'm using a Windows 10 64-bit laptop with two USB ports and a USB-A to USB-C cable from Anker. When I started this process, I was able to get my device to appear when using -adb devices-, but now it won't any longer. I've installed, uninstalled, and reinstalled the drivers, both manually and by using both Android Studio and SDK manager (like in Heisenburg's Rooting instructions, post 1, Prerequsites: paragraph 4), but nothing will help it appear on my devices list.
As I understand it, I need to enable USB debugging on my phone, but since I can't boot, that seems not to be possible.
Any help would be greatly appreciated. I've searched dozens of websites looking for suggestions but nothing I do seems to get my phone to appear on the devices list.

Use fastboot from the bootloader instead of ADB. Use fastboot to flash the factory image. Same thread you mentioned.
ADB does NOT work from the bootloader. Only fastboot does.
You use ADB while booted into Android or in recovery. From the bootloader, you use fastboot.
Try again with "fastboot devices" instead of "adb devices"
Hate to say it, but you wasted a lot of your time reinstalling those drivers. If you had it working earlier, I can't see it just stopping. You just used the wrong command. ADB will only ever work booted to the OS or in recovery. Never from the bootloader, even if correctly installed. Same for fastboot, only from the bootloader and never from recovery or booted into Android, even though everything is installed correctly.
Read over that thread you mentioned a few more times. :angel:

Amazing. I have no idea how I could have not known that. Thank you for your help.

Glad you got it sorted!

Fastboot not detecting device on Windows XP

First let me get the stats out of the way in case it's a compatibility issue (doubtful):
Mytouch 3g 32b
Hboot 1.33.2005
Radio 2.22.23.02
Running on the last cm6 nightly (307, i believe)
Using this kernel: http://droidbasement.com/db-blog/?p=1531
All flashed through recovery.
Ok, so the problem..
Following this guide, http://forum.xda-developers.com/showthread.php?t=532719, I successfully got the ADB to work properly (calling "adb devices" on a terminal returns my device). However when I boot the phone into fastboot, connect it to the PC via USB and call "fastboot devices" through the terminal (yes, I first cd to the android-sdk/tools folder), it returns nothing. Calling something like "fastboot reboot" simply returns "<waiting on device>" indefinitely.
I googled for HOURS last night searching for a solution but to no avail. I uninstalled the drivers via the Device Manager and tried the PDANet method, but nope. Uninstalled drivers again, rebooted everything, and reinstalled using the method posted in the above guide again, pointing it to the google/usb_drivers folder, just in case I had f*'d up somewhere along the way. I just ended up with the same problem. ADB works. Fastboot doesn't. What am I doing wrong? :/
Basically, I'm stumped. While it's not completely necessary to get this working, I'd like to free up some ram on my phone (http://forum.xda-developers.com/showthread.php?t=831139) and for this I need fastboot. I'm not that noobish so I'm willing to experiment. Any help is appreciated.
Nobody? :/
Thanks to my persistence I finally got it working. I'll share in case anyone else has the same problem.
Apparently there were still old HTC related devices under the Device Manager that would not show even when I clicked on "Show hidden devices." I fixed this by adding a new system variable.
Variable name: devmgr_show_nonpresent_devices
Variable value: 1
This allowed me to see a bunch of HTC labeled grayed out devices under 'Disk drives' and under 'Universal Serial Bus controllers,' some grayed out USB Mass Storage Devices and one USB Composite device which I believe was also a culprit. Uninstalled all of them.
I then restarted the process of setting up ADB using these drivers, mediafire.com/?wzdjcmowziw, which I got from the guide I link to in the first post. Then when I hooked up the phone to the PC under fastboot mode, I used the drivers supplied by PDANet. Worked immediately.
Thanks for all the help. (sarcasm)

Need Help Unbricking Nexus 7

The problem is I can't unbrick and restore my nexus to stock rom.
I can't boot the device and I'm only able to boot to bootloader. However, my computer doesn't recognize the nexus. It keeps saying Window cannot recognize it whenever I plug my tablet to the computer in bootloader. I tried uninstall and reinstall driver several times, but none of them seems to work . ----> That means I can't even use adb to restore the phone simply because my tablet is not recognized in window.
Is there anyway to fix this problem? I really need your helps as soon as possible.
Thank you for reading !
Get to bootloader. Then use Wugs toolkit, open advanced options. On the very left is something like "temp boot to recovery". Once that boots it to recovery, ADB should work. It did for me. I was in some trouble last night and got out by this. If you know how to use adb/fastboot commands, you should be good. And I uninstalled my drivers and when I plugged it in the device automagically reloaded the drivers. But you have to do it a few times. Had to do it in bootloader, recovery, and another point. Anytime it asks to load drivers/etc do it.
I can't boot to recovery through Wug Tool Kit. It keeps saying Fastboot device was not found >"<
By the way, whenever I connnected my device to computer, the bootloader freezes :|
What were you doing before you go into this situation?
I was on Glazed Jelly Bean rom and wanted to go back to stock rom. I used nexus 7 toolkit to do all the work for me. However, there was something wrong like the toolkit didnt extract the stock img right or something like that, my tablet got bootloop, and what happened next was what i had been telling you guys.
Best bet is if somehow you could get into recovery or get adb working. Might want to uninstall drivers and install again and reboot computer. I would suggest using this thread and flash things manually back to stock. http://forum.xda-developers.com/showthread.php?t=1907796 but you would need adb working.
When you power off device and use volume and power can you get it to go into boot loader then plugged into computer try to get to recovery or adb.
Consider deleting the drivers from Windows after uninstalling them otherwise Windows may try to be "clever" and reinstall the bad driver when you plug the device in. The Nexus 7 drivers from Asus can be downloaded here and Google's USB drivers are here

try connecting to the usb port at the back of your computer
Paranoid flashed with the bricked kernel did this to me once right after the move to 4.1.2. Even with a full wipe and all the usual safety precautions it just stuck on bootloop forever and wouldn't let me in. I chalked it up as that's what I get for being the guy that's never satisfied with stock. I was unable to get my nexus7 fixed. I sent you a suggestion on pm though.
Never mind everyone. Thank you so much for your help.
I tried install the nexus 7's driver on another computer and it recognized my device in bootloader mode, and restore everything back to stock now. Thank you so much!!!!
Mine did that to the first time I tried. After I got it to work, the permissions were all messed up and I could not get it to download anything off the web and I was getting a playstore error 90% of the time as well. I finally just wiped everything on my tablet, installed the stock rom via N7 toolkit, then reflashed smooth rom, and all is working now. It may have been a bug with the older version of N7 toolkit, as I updated it before I reran everything.

Soft brick? (No ROM installed but can sort of boot into recovery)

howdy y'all,
so im trying to help out my buddy. he currently has no os installed as well, but can boot to bootloader and twrp recovery 2.5. no idea how he has that but I figure I could just mount some zip files and be on my way. Currently whenever we try to do anything in twrp(ie wipe/mount) it is just hung up on unable to mount /radio even when all I have checked is system. I can't use adb or fastboot as far as I'm aware of; I've tried to use the unified android toolkit from skipsoft but its no dice since I was never able to turn on debug mode to begin with? So yeah any help would be much appreciated
oh and I know its not my cable or usb ports since the tablet can still charge.
Also this is the 2012 N7
Hi,
You'll need to get adb and fastboot working, best approach is to wipe and flash factory images through fastboot but may also need to use adb for e2fsck

I don't understand how I'm supposed to get fastboot working since I was never able to enable debug mode on the device in the past let alone now that it has nothing installed. And from what I can understand from the instructions I need the drivers to be installed after I plug in while under debug mode for the sdk to work.
I attempted to install the nexus 7 driver from here: http://support.asus.com/download.aspx?SLanguage=en&m=Nexus+7&os=32
However it looks like I already have the files on my computer from a previous attempt with Skipsoft's Android toolkit?
Because of this I'm unsure of how to move forward with this fastboot business.
fastboot doesn't need debugging on or an os installed, just a functional bootloader
You will probably need to manually update the drivers yo the proper ones
I see, how do I go about manually installing this driver then? I'm assuming I need to go through some sort of windows device tree? Or can I just extract a file somewhere?
You can download usbdview (just search Google for a free download) to see what driver is selected when you plug in your tab easily
Or you will need to go into device manager and select to manually update the drivers, don't allow windows to select but manually choose it
There are loads of instructional videos on YouTube for you if needed
I know this is a super late response, but I never managed to get around to trying to find out how to do a manual install. Just tried today using the Nexus Root Toolkit v.1.9.9. I still can't figure out how to manual install the driver because my issue is that windows doesn't recognize anything is plugged in, and all of these guides do state that I should have had usbdebugging checked. I can't seem to find a specific guide that correlates to setting fastboot up exclusively like you mentioned.
Also, using usbdeview like you said I could see that I have installed a google nexus adb interface, a google galaxy nexus adb interface, as well as the mtp usb driver.
Sorry for all the handholding, but this really is an issue that I've never have encountered and I can't seem to manage.
Hey again
There is a fastboot guide in the first post I linked you to
If you can't get fastboot to recognize device in bootloader mode it is possible the USB port is broken, but more likely an issue with drivers, cord or PC
So try a new USB cable, or a different PC
Try try again with drivers, uninstall and reinstall
Unfortunately this type of trouble shooting is hard to do without device in hand

Need help - OP 6t not recognized in fastboot

Hello, a few weeks ago i got my OP 6t. Due to my positive experience from my previous phones (LG G3 and G5) and what i heard from OP i tried to flash twrp and planned to install magisk. I followed the instructions here on xda to unlock the bootloader, it got recognized as device in adb and i could reboot it into the bootloader, but then it didnt recognized it in fastboot, it looks like im missing some sort of drivers, because when im in fastboot in the win 10 device manager its called "android" with a yellow triangle, i tried multiple guides already, but i had no success. Its the unbranded version with 8 gigs and 128 gig. I can provide more info if needed. Help would be very appreciated.
Did you follow funkwizard's guide in the guides/news/discussion forum? It's stickied at the top.
Anyhow, if you followed the guide, he provides this link (https://drive.google.com/file/d/1L7EZGx5mgeQYXO19Vsp9FWu9GXhF45Qs/view?usp=drivesdk) for the OP6T drivers that need it be installed.
He then provides this link (https://drive.google.com/file/d/1-uWQn-oHu_ROuDVCzIyrExoRbsSBYTtU/view?usp=drivesdk) to update your ADB/fastboot to the latest version.
Complete both of those steps and your phone SHOULD be recognized in fastboot. Good luck.
I have read his complete thread and im still stuck with the same problem. I deinstalled all phone related driver and only installed the one from the thread, opened the command prompt via admin and under device manager is still the yellow triangle beside the android device. I tried to install the driver manually via the google universal driver, but windows never found any compatible drivers.
And just to be certain, do you have USB Debugging enabled in developer options?

Yupp, but i have to say that i had to tap it four to five times until the confirmation window popped up.
I had this problem few hours ago, and this is W10 fault. For me solution was that:
instal drivers from guide,
enter fastboot mode,
remove phone from device manager and unistal drivers,
replug phone,
let windows find drivers automaticly when in fastboot mode.
And that's it, fasboot comands works now.

Fastboot Not Recognized

I am not able to get Fastboot to reconginze my One Plus 6T. I have reinstalled the drivers numerous times to no avail. I have changed ports to no avail. I have change USB cables to no avail. Is anyone else having a similar problem and if so, any solution?
BTW, I am using a Windows 10 computer.
Also, I was able to install the International Version on my TMO variant One Plus 6T via the MSM tool method, so the drivers appear to be installed correctly.
Thank you in advance for any assistance.

Delete the drivers you have installed, boot into fastboot and have Windows automatically detect and install for you. Have you tried that? What source did you get your fastboot drivers from?

Oh man, I had issues getting my 6t to connect to my PC when I first got my 6t. The answer for me was to plug my phone into a USB 2.0 port on the BACK of my PC instead of the front USB ports my PC has. Try using the back USB ports and let me know if that works for you!
Thank you all. I will try these suggestions later today and report back.
I tried the suggestions and still no success in fastboot connecting with my device. Thanks again for the suggestions.
After trying to multiple times reinstall the drivers, manually selecting "Android Bootloader Interface" did the trick for me on win10:

Thank you! I can't believe I didn't think to check that.
it is solved for me oneplus 6t not recognized in fastboot
{ solved for me } hello brother, i got this problem also my head was about to explosing, install/uninstall drivers and adb drivers also, without any success, when the device is on normal mod the adb terminal can recognize it and in fastboot mod not recognize my devie (the list empty).
i was trying to install TWRP, so i have reboot my device to fastboot mod, and i didn't think about List of devices (because it not show my device) i wrote the comand to install TWRP directly so it success to install 100%,
so no need to write : adb devices when your device is in fastboot mod, it will not show you in the list, but you can apply what you want normally
good luck

This is why I use Linux in my LOS Install Guide. You can boot Linux from a USB without installing it. Fastboot and ADB just work, without any drivers. Install TWRP, reboot and your PC will be back to windows. My guide covers installing TWRP.
Really need help. I'm going in circles and wasting a lot of time:
I'm attempting to root a OP6T A6013. Its already been unlocked.
My device is recognized when powered up as an ADB device.
But when i boot into the bootloader it isnt recognized as a fastboot device, and my laptop (Win 8.1) shows ""device malfunctioned. USB not recognized". I've also been trying to install the OP driver but I'm not sure its working correctly. But would that cause the problem with recognizing fastboot?
I've root my OP7Pro (twice, actually) and though I had some driver issues then eventually figured it out. But I never had issues with fastboot.
Any tips or direction?
Hey all , replying to share my solution to this exact problem I was having..
My OP6T (T-Mobile converted to international) was not showing in fastboot devices but showed in ADB.. after hours of searching google and XDA , I ended up just plugging my 6T into another computer and it worked! , instantly recognized my device without hassle.
So just a fyi, it could be something simple as switching USB ports or even another computer.
hopefully this helps if someone get's stuck at this point.
I had this issue with a OP8Pro... I went to Windows Update and selected View Optional Updates and found Android Bootloader Device on the list. I selected this to download, and then fastboot worked perfectly.
