adb/fastboot - Nexus 6P Q&A, Help & Troubleshooting

Hey guys,
Back May when dp3 came out, I went ahead and installed it. Now I'm stuck without a working twerp because I'm encrypted. Problem is I can get dab to work when the phone is on but cant connect to it from bootloader. I'm using the same pc from when I first rooted it...so I know that end is ok. Here's what I've done so far.....I've uninstalled all other drivers and have installed and checked with googles usb driver and clockwork mod universal drivers. I've used usbdeviw to make sure I had no conflicts there. I've tried all usb ports and different cables. I'm using win10, sdk is system wide, everything is up-to-date.

One more way to confirm is by connecting your device to another PC, and check if fastboot works while your device is in bootloader mode, and adb, when your device is booted in the operating system.

While it is booted in the operating system, can you get it connect through MTP?

So while in operating system, and USB debugging enabled, you cannot detect it through the "adb devices" command?

ADB doesn't work in the bootloader, only in recovery and booted in Android. You must use "fastboot" <command>, like "fastboot devices" while in the bootloader.

Mate you are doing it wrong here. ADB only operates when Android is loaded into the operating system or when sideloading. While in the bootloader, you need to operate over fastboot. So the right command command would be:
Code:
fastboot devices

Root GT-N8013

Hello All,
I've been trying to root my device following this thread:
http://forum.xda-developers.com/showthread.php?t=1957002
However once I reboot the device pressing the volume down, I don't get the ID:COM to light up in yellow.
If I plug the device in while its on, I do get the ID:COM to light up, so I'm guessing the drivers are correctly installed.
I have no idea what to do...
The reason for using this specific method, is because its supposed to be good for beginners.
I cant seem to find much additional information about what else to do.
Honestly I'm clueless and been searching around for a while online.
Any help would be appreciated.

Bricked for good?

Hi, I tried to push the 4.3 update and unroot my device through Wugfresh kit and all went well. But when it initially booted, I had this constant popup saying that "Bluetooth Share has stopped working" making the device unusable as it was stuck on the welcome screen. So, I rebooted into bootloader and tried to use the "Unroot + Stock" option saying my device had a soft brick and flash 4.2.2. But now nothing starts, it stays on the Google screen and that's it. I am however able to boot into recovery. I've checked the manual way of doing it but it says my USB debugging needs to be turned on (but I can't boot into the OS to do that)... To top it up, my computer isn't recognizing my device. I've used mskip's toolkit as well, no go. Are there any solutions or is my table gone for good?
Thanks
Oh yeah I tried again with Wugfresh it says this

You need to install this to use ADB in recovery.
Thanks, I've downloaded those drivers and followed the instruction for windows 8 but still adb doesn't recognize my device and I cannot boot into the device to change it to debugging mode as I cannot go past the Google screen =\ any other ways to make it recognize my device?
my brother has a nexus 7 do you guys think if I deleted all the drivers and put his into debugging mode it'll install drivers for mine too?
What you installed is needed to use ADB while in recovery. Here is the latest Android Composite ADB Interface Driver from SDK that you need for use of ADB while booted and fastboot in bootloader.
http://d-h.st/kDu
You do not need USB debugging to use ADB while in recovery or fastboot.

Hi, thanks again. However, I have no idea what to do with those files (the drivers) with ADB
Install or update through device manager.
I had a similar issue. My pc went to BSOD in the middle of writing system. To made it worse, fastboot stopped working altogether. My solution was to do the flashing from my Linux partiton. I know it's a crazy advice, but linux commands never fail, and you won't need drivers at all.
Still, try to use the "flash-all.bat" from the factory image, and stay away from toolkits.
When I plug in my nexus in (while in bootloader) on my device manager this pops up but then I try to update the drivers it says it can't update unknown device
You may have to disable Window's Driver Signature Enforcement.
I do not have a linux partition I'm using a windows 8 and I have 2 other PCs with win7 and xp. My windows 8 digital signature checking is disabled.
EDIT: plugging my bro's nexus did not make mine get recognized by the PC. I am installing linux on my other PC just to see if it works + i've never used linux so a new experience
running it on ubuntu 12.04 did not help either =\ while in bootloader in terminal I type in adb devices and not devices are listed under "List of devices attached"
When you are in boot loader mode you need to use fastboot instead of adb, I.e. try:
fastboot devices
(I suppose you have the latest SDK installed ...)

Well guys, I've been doing this for about 12 hours straight lol and I'VE FINALLY DONE IT THROUGH UBUNTU OMG I LOVE UBUNTU! YES!!! Thank you all for the amazing support and advice! Much appreciated. Thank you ALL! :highfive:
It's not as if your device was bricked in the first place
Installing the drivers in Ubuntu is very easy using "sudo apt-get install android-tools".

My g2 stuck at fastboot mode

Hi all,
I'm really desperate because my LG stuck in a boot loop and it can only get in the download mode.
I've read the thread about using fastboot command to restore to stock but my condition seems to be a little bit difference
First
i've got these command while plug my phone in
[860]fastboot mode started
[1070]-reset-
[1080]-portchange-
[1150] fastbootrocessing commands
Normally there would be a [910]udc_start() in the second line but i don't have it
Second
my command such as fastboot reboot or fastboot erase all stuck. When i unplug the usb cable it appear the too many link line like this
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Is there any other way for me to return to stock or i can't use my phone anymore?
Note: i've tried to change the usb cable, usb port and even another computer and all of them stuck at the command line.

TWRP Not Opening And adb Showing Unauthorized.

Help Me Anyone Guys, I'm In Extreme Problem.
Unfortunately, I Did Something With TWRP Backups, And Then TWRP Is Not Opening, It Just Restarts, And When Connected To PC, adb Shows Device Unauthorized And Doesn't Show Any Authorisation Pop UP On Mobile. What Should I Do?
I Can't Even Factory Reset From Settings As It Makes A Reboot And Does Nothing.
Help Would Be Extremely Appreciated.
Thanks In Advance.
Reinstall drivers properly, mostly don't try in win 10, 10 is **** causes bugs, use win 7 or 8 or 8.1 also enable oem unlocking from settings and enable USB debugging

Hello Brother, Meeting U After Many Days.
First, I Have Moto Stock ROM, And That **** Doesn't Has Revoke Option.
Last, Yes I Was Using Windows 10 And It Detects The Device But Doesn't Gets Authorized By Phone Due To No Pop Up.
Thanks
EDIT : TWRP 3.0.2-2 r2 I Think.
EDIT 2 : I Restored My Old Backup And Unfortunately I Forgot To Wipe Partitions And Then Got This Problem.
I am not what exactly went wrong. Boot into fastboot mode and If you're PC is detecting fastboot, try booting into TWRP using an image and see if you can restore a backup.
Or if you have your personal files backed up, just flash the Stock Nougat ROM via fastboot.
That will clear up everything. Or if you want a more flexible ROM, just go for a custom one

Did you tried other computer/laptop, or change the port you are using, try to change the data cable as these are the basic steps we do in these cases.
If problem continue persist try to use the Windows 7 for flashing via abd, also try to boot into safe mode and then try the adb may help you.

Need some help for a bricked pure

I have not touched this phone in a year, so forgive me if im rusty.
I embarked on a project of compiling slimroms 7.1.2 for this device a year ago, and made a rom that made it onto the device. Now, Here is my mistake. At the time when i built the rom, the nougat bootloader for this device was not out yet(i think, as my bootloader is on a0.4d aka dated 2016-11-30) Giddy that i had finally built a custom rom that worked, i hurriedly flashed the device through the recovery(twrp at the time) and thats when the issues happened. The device will not charge past 1 percent, and in an effort to fix, without knowing that my outdated bootloader was the issue, i decided that installing stock recovery was the best option. BIG MISTAKE. as i now cannot flash anything in recovery. i keep getting signature verification failures and what not.
With that backstory out of the way, here is my issue. I cannot flash anything in fastboot, because when i connect the device to windows i get
Code:
Windows has stopped this device because it has reported problems. (Code 43)
A request for the USB device descriptor failed.
Yes i have updated the drivers and when i install the motorola drivers manually i get this:
Code:
This device cannot start. (Code 10)
A request for the USB device descriptor failed.
this is the single most thing that is keeping me from reviving this device. I have tried using linux, but the device just doesnt show up. I have tried multiple usb cables. so i know thats not the issue. any help would be very appreciated.
UPDATE: i have done some digging around and no loader files are working. (using a 32gig class 10 microsd). Also, It is on stock recovery so i cannot flash anything other than stock images, which if i am correct, none are recovery flashable, only the otas are. When i try to flash an ota it doesnt work because it is expecting stock apps in system, which are not there since i am on a slimrom rom.
TLDR: i have stock bootloader and recovery, (24.49-18-8/4) but have a non rooted slimrom 7.1.2 which shows up in windows as get device descriptor failed(unknown device). if there was a way to root slimrom 7.1 without usb and with stock recovery that would help alot.

Its noones fault but my own, so i will chalk this one up to a loss lol
