As it says. I've used this cable to unlock/root my HTC M9, and the Win10 machine I have shows the Shield's storage when connected. However, neither ADB nor Fastboot are connecting. Error message says 'Error: device not found" or something like that. What am I doing wrong?
Disregard. Had to install the device drivers for Win10 from Nvidia.
adb reboot bootloader works but not fastboot oem unlock
I can reboot bootloader and get to the fastboot menu, but the fastboot oem unlock command does nothing, the command window simply says "waiting for device".
When I go to device manager on my PC to change to the Nvidia drivers, windows says I already have the best driver installed.
Any ideas what to do to get this working properly? Is the "hardware method" better somehow?
Thanks.

So I am having a lot of problems with trying to root my nexus 7. I'm pretty sure it boils down to a driver issue but I'm not sure. I have tried installing the correct drivers over and over again also uninstalling other hardware manufacturers drivers and I cannot get adb to recognize my device when it is shut off and in the boot loader.
When the tablet is on and I have debugging on, adb shows up and is recognized, however my problem is that whenever I reboot into the boot loader I lose adb recognition. So therefore I can't root or do anything else. Fast boot commands work fine its only the issue with adb.
If anyone has any suggestions as to what I can do I would really appreciate it. I don't know if its just a hardware issue or something I am doing wrong on my end.
This is also not my first time manually unlocking/rooting a device
When you initially connect, the device shows up as a "Nexus 7".
When you reboot into the boot loader, the device name changes, and there is no driver for that device.
As far as I could tell, I would have to do the root process under Linux to avoid this issue.
As for me, I just ignored the issue. By the time you reboot the bootloader, you are already rooted.
The only thing you do after the reboot is rename a file. For now I am missing that step...
Yeah I'm using windows xp. When its in boot loader it does change names. I can unlock the bootloader via fastboot but can't do anything with adb. Lol I don't know what else I can do, I'm at a loss.

Like I said - I think you are done...
Install a terminal on the Nexus and see what it says to "su". I use one called "terminal emulator". Works fine.
I think fastboot uses adb.
If you connect your Nexus, and type "adb devices" in a command window what does it say?
I believe it says devices attached or something like that. (Not at my computer) but doesn't give me a serial # like I think it should.
If you do not have USB Debugging checked, "adb devices" will just show the List of devices line.
If I set USB debugging on, "adb devices" also shows the Nexus serial number.
If you don't see that, I would double check the device driver you are using.
Under Device Manager, Android Phone, Android Composite ADB Interface it shows:
Driver: Google Inc.
Date: 5/24/2012
Version: 6.0.0.0
Digital Signer: google inc.
Well if I have USB debugging on and tablet on and do adb devices I get the serial # but once I go into boot loader and do adb devices I don't get the serial #.
For device manager I can choose adb interface or adb original interface. I'll have more info when I get out of work and at my computer. Do you have a link to the drivers you used? Or where to find them. Because I have tried a couple of different drivers posted around to no avail.
BTW thanks for helping me out.
I would not use any posted driver - you don't know where that thing has been.
Download the SDK from Google; the correct driver is in there.
Just point the device manager to it when you install drivers.
There are a lot of good descriptions on installing drivers in the other nexus forums
But - again - I think your device driver is fine. You will not be able to talk to the Nexus from ADB after you boot the bootloader
Bootloader has a different device name which ADB can't use under Windows.
Use Linux if you want to do that.
ok, so pretty much what happens is when my tablet is powered on with usb debugging everything is fine and ADB is recognized. Now my problem seems to be when i reboot into the bootloader it seems as though the drivers dont stick and it asks me to install the drivers again and this is where i have had all of my issues. When i type in adb devices in, it just tells me "list of devices attached" and wont let me do anything else (fastboot works). Like i said i was able to unlock my bootloader but i cant flash recovery or do anything else.
When i go into device manage to select the drivers it gives me the option of choosing between adb interface, adb bootloader interface, adb orignal interface and nexus 7 bootloader interface. I have tried all options and nothing seems to work. I have tried multiple usb cords and ports.
If anyone else has any suggestions it would be much appreciated.
I didn't read through everything but your initial problem is adb doesn't work in the bootloader that's where you use fastboot commands either boot into a custom recovery or just boot up normal and make sure debugging is checked.
Try running fastboot devices and see if it shows up. What you need to do is have bootloader unlocked and dismiss the super user zip floating around here pot that on sd card download cwm recovery image floating around boot into bootloader then
fastboot devices
fastboot flash recovery name_of_file.img
fastboot reboot bootloader
select recovery from the menu
Flash the super user zip
Or download a rom that has root and put that on sd card instead of super user zip and after doing the steps above then selecting super user zip select the rom you downloaded and flash. If you're on Linux run sudo first.

I just got a new grey LeMax2 X822 with 16S stock rom. I have enabled USB debugging and bootloader unlocking, enabled MTP device when plugged, I can see it as "Le Max2" MTP and can browse internal storage. I've tried different android adb drivers and two computers (win10 and win7). There is no yellow question mark, and device is recognized as "Le Max2" on win10 and "Android ADB" on Win7. However when i run cmd and type "adb devices" the list is empty, and when I type "adb usb" - I get "device not found". I've tried everything I could think of. What's the problem?
I want to install CWM recovery and a rom. But I can't! Please help, I don't know what else to try.
Update: updated to stock 20S via stock recovery. "Fastboot devices" works and I was able to install TWRP with "fastboot recovery twrp.img" command. So I guess I will try to flash the custom ROM now... ADB still doesn't work.

OK, problem somehow solved. As I had fastboot command access I flashed CWM recovery. After I've done that and booted to recovery, and connected to PC, there was a unknown MTP device in device manager with yellow exclamation mark, as if there is no drivers. However "adb devices" suddenly returned "device code - recovery". So I pulled full CWM backup to PC and was able to flash madsurfer's 20S ROM. So far so good. Will test how it works...

Had this issue on my just received Le Max 2, and this did it. Thanks a lot.
guys I'm in a bad situation, phone is without OS and I can only access to recovery or bootloader, I have a twrp installed and I can't access to an USB otg (simple usb doesn't even blink like they are not working, If I connect an hdd it doesn't recognize it but gives it power) and I can't access to the phone as MTP or with adb devices or adb sideload. Even on bootloader mode device isn't showed when I try the command "fastboot devices" and it says "download mode = DISABLED".
so I only have access to twrp with those limitations, I need a big help, phone is with BTL unlocked and with expired warranty.
thanks in advance

Download mode=disabled is the default (normal) displayed in bootloader mode. You seem to infer that is what fastboot returned when you typed devices? MTP works in TWRP automatically when it loads. Sounds like you may have a PC driver/cable issue. When you plug the device into your PC, how is it recognized?

You are using OSX, right? Fastboot commands should start with ./ before each command. For example: ./fastboot devices, or ./fastboot flash, or ./fastboot reboot bootloader. Same applies for adb commands. If you are already familiar with flashing images, read my post below about OSX and fastboot.
Do not click into the thread because it is for the Nexus 5X new users guide.

Hi, I've my new essential.
I can't flash a factory image, my device is dectected in fastboot, I have unlocked the bootloader, but when I click on flash-all in the image files, I have "waiting for device". I can't understand why because ALL OTHER COMMANDS have worked : fasboot flashing unlock, USB debugging, fastboot devices...
What can I do ? (In the control panel, device is detected without a yellow mark or something else. Everything should be fine.

Still seems like a driver issue. While in bootloader, you could confirm this by trying the command "fastboot devices". If nothing shows then check your device manager. If you are seeing Mata, it's your issue. For some reason every few times I plug in, it'll default back to that and have to manually update the driver to the bootloader driver. Just choose from list of installed drivers as the update method.
Also, if you have USB 2 ports, try one of those. I couldn't get anything to flash when I had it plugged in one of my USB 3 ports.
Could be cable issue, USB port issue, driver issue or you can try updating your adb setup etc... I used the Minimal ADB and Fastboot. Mine was out of date and wouldn't recognize device in fastboot after the Oreo sideload.
Works perfectly with the Essential official drivers in Win8.1Pro now.
The cable is brand new by anker, and works perfectly. Drivers and adb are updated.

Something that was odd that may help (assumed it was just my environment setup). I had adb installed to C:\adb and only way fastboot will work consistently for me is to run commands from that directory. Could be unrelated but thought I would mention it.

Try copying fastboot to the folder that has the flash all.bat
What operating system?
Where did you get your driver's?
Reason I ask is at first I had driver's auto install from a Samsung device that I used previously. Caused an issue where it wouldn't start the fastboot process and device got stuck at first step.
Take the system driver of your operating system from essential homepage... Was the trick for me

It's always recommended to use the adb/fastboot provided by Essential (gets installed along with the Windows driver). From the error message, it looks like you are using a different fastboot executable. If you have more than one adb/fastboot package installed on your PC, make sure to use the one from Essential. You can see the path to the executable by running "fastboot --version".

Ahh... Yeah, that's often the issue. Still doesn't make a lot of sense to me, because your error msg was "unsupported option". Well, good that it worked for you.
I'm dumbfounded. I have unlocked bootloaders and rooted for years. Just got my OP8P.
I also have a new Microsoft Surface Pro with Windows 10.
I installed ADB, installed Fastboot.
Unlocked developer options and turned on USB Debugging and Developer Unlock.
Windows device manager shows ADB INTERFACE for the my device in device manager.
I can open can open Power Shell and/or the CMD prompt. I've done both.
I can type adb devices in the command prompt and I CAN see my device.
I can reboot it fastboot from the CMD prompt so I KNOW Wndows sees my phone.
BUT ONCE I'M IN FASTBOOT, the problem starts.
Fastboot does NOT see my device. Commands return the words "Waiting for Device..."
I BELIEVE the issue is with the drivers. When I boot into Fastboot, my device location changes in Device Manager from USB>ADB Interface to Portable Devices>Android.
The Android Device icon has a yellow triangle with an exclamation mark. It's says the driver for this device is not installed. But everything was working fine and the drivers were fine while the device was powered up normally.
If I try to manually install the driver it fails and says "cannot update drivers for your Android".
What heck is going on? What did I do wrong?
I've uninstall and reinstalled the drivers direct from Oneplus. I've uninstall and reinstalled the drivers direct from Google. 'I ve uninstall and reinstalled the drivers direct from Windows.
Why can't device and drivers be recognized in Fastboot. And why can't I update the drivers for the "Android" device?
