You can use the command "adb reboot-bootloader", I didn't see anyone else try this on here. Unfortunately, fastboot still doesn't recognize the device. I used the stock USB cable, I also tried doing it with my factory cable, but the device rebooted to a black screen and I got it recognized as "Qualcomm QH-USB QDloader"

Really? & just what command did you send using fastboot? Unless you have a magic kernel & bootloader, there is no fastboot access without passing the key. The way updates are performed on the KF HDX are fairly abnormal compared to other devices, which is why you see two kernel, stream writer & other such files & apps.

I used getvar, and it worked fine (but most the of parameters don't), boot and idme don't work because it's locked, and oem unlock doesn't exist. But what your saying is that I shouldn't even be able to do any of this?
i look at the picture and the kindle is not hdx.
i've searching for fastboot cable on ebay but didn't found, the cable only work for kindle HD
so for there is no fix for bricked kindle fire hdx
You can turn HDX into fastboot mode by "adb reboot bootloader" if device is alive.
But you can not flash anything anyway - error "flash not allowed for locked hw".
Fastboot cable perfect fit to HDX too. But it turn device in Qloader for QPST.

Hello,
I'm trying to flash a TWRP, but for some reason the phone doesn't show up any more in adb when in fastboot mode (at the bottom of the phone screen it tells me to connect a USB cable). It was showing fine until yesterday. I have tried several different USB ports. The cable is definitely working (in fact plugging and unplugging it causes Windows to notice and make a sound, and also it works fine in ADB when the phone is booted up.
The only thing that I can think that happened since I had last connected to it in fastboot mode (to unlock the bootloader) is that I connected my PC to a couple other phones (Galaxy S3 and Nexus 5) using them in MTP mode. I have reinstalled Google and universal drivers several times, deleted the device from device manager, etc etc. No good.
Any ideas?
We gonna start off with are you using the right commands? Using Fastboot devices?
You must remember ADB and Fastboot are two different things. ADB is only when the phone is on and fastboot is only in bootloader mode

Arghhhh :-|
that was it, I was using adb devices. Thanks! (I feel dumb now)
I have followed Heisenbergs instructions to the letter but when I issue the adb devices command it just returns the string "list of devices" and that's it. Fastboot devices doesn't work either.
So I'm stuck at the start. Can anyone help me? From what I can tell I may need drivers but I'm new to this so I don't know.
I can give anyone more info if they need it.
I believe part of the instructions are to install the Platform Tools, which should include drivers. Try running the SDK Manager and updating or installing the drivers again. Also ensure you have USB Debugging ON in your Developer settings and OEM Unlocking enabled. Lastly, tap the notification in your shade about the USB connection (I think it defaults to Charging Only) and change it to various modes. Mine seems to only work on PTP mode. When you run the adb devices command you will need to authorize the connection on the phone end the first time by clicking OK so make sure the screen is on and unlocked so you can see it.
Hope this helps.

Me personally do not get any strings of data returned when im on fastboot
i open CMD, run ADB DEVICES, get message saying the port is opening, and then listing devices... which is empty
but i am able to flash anything i want using fastboot....
try this command and see if it works after that... fastboot reboot-bootloader
it should reboot bootloader for u.. thats a easy way to know its responding to u

Yeah I tried every option. Nothing.
The instructions say the fastboot devices command should return my serial number and it does not.
When booted into the bootloader one it tells me on one line phone LOCKED and on another line says download mode DISABLED.
Don't know if this has anything to do with my problems but I still cannot get a return on the fastboot devices command in order to proceed with the unlock command of "fastboot flashing unlock"
remember that u need latest fastboot for this to work.
did u updated the SDK manager to the latest? i had to do that in order to work for 6P

I had the same issue ,it was down to when I plugged the phone into the PC for the first time,it installed the Google.USB driver ,but it didn't install the driver for the adb interface,I had to download it from Google and install it manually
I also had the same issue, I had an old Clockworkmod generic driver that I was using for my Samsung Galaxy S5 installed.
Go to Device manager (either type it in the start menu, or: right click This PC, click manage, and click device manager), plug in your unlocked Nexus 6P phone and watch for a new item to pop up. If it says android something, uninstall it. I had to uninstall 3 times, then reinstall the drivers from the SDK before it would work.
I used the skipsoft toolkit to install the fb drivers; worked for me. http://forum.xda-developers.com/nex...ol-skipsoft-android-toolkit-nexus-6p-t3234159
but like others said, you may have to manually remove any that are already installed in windows, although I think that is one of the options in the toolkit.

I'm trying to unlock the bootloader on my XT1622.
I can transfer files etc and backup when connected to PC and in Windows
I have installed the drivers and fastboot and adb and opened a cmd window in Admin mode in the directory where fastboot.exe and adb.exe are installed.
I have restarted the phone in fastboot mode (power up plus Vol Down) and connected by USB cable to my PC but when I type adb devices I get no information coming back.
Does anyone have any idea, please, where I may be going wrong?
Anyone able to help, please?
My post above is getting a number of views but sadly no replies.
Since posting I have tried different cables, different USB ports and even installed the drivers on my wife's laptop, but to the same effect - the device is seen in File Explorer but after booting into bootloader both fastboot devices and adb devices return blanks.
I think I'll just give up on the idea, which is a shame as accomplished it easily on my old Nexus tablet and on previous Moto G iterations.

adb mode doesn't work when you are in the bootloader. But fastboot should. Boot into your phone and go to settings/Developer options and make sure you have OEM unlocking and Android debugging both enabled. Then on your PC connect your cable and open a command window. type the command "adb devices" and see if your phone shows up now. If so you can then boot into the bootloader via the command "adb reboot bootloader" While in the bootloader type the command "fastboot devices" and see if your phone shows up. If so you are good to go.
Oh, and I am assuming you have a non-Amazon model?
Still no show
Thanks Palmyra. I have followed those instructions to the letter.
In Developer options both OEM unlocking and USB debugging are switched on.
When I connect to the PC and run adb devices in a CMD window it first responds that daemon has been successfully started then that the list of devices is attached but it then returns me to the command prompt.
I did then try 'adb reboot bootloader' but it returned 'error: device not found' - not unexpected given the first command result.
In File Explorer however under this PC it does list Moto G(4) and I am able to explore the phone contents there.
It is not an Amazon model.
I really am at a loss to understand why this is happening.

Thanks. Yes, I have installed Motorola Device Manager. In Windows Device Manager the MotoG4 shows under Portable Devices only when USB set to Charging or File Transfer and as an Android device with Motorola Device Manager when connected as PTP. The situation has persisted since updating to Nougat and 'adb devices' draws a blank no matter which USB connection mode I use.

Did an RSA key dialogue ever pop up when you plugged it into your PC?
If fastboot shows no devices when your phone is in fastboot mode (voldown+power hold), then something is seriously off. Have you tried multiple USB cables?
On your wife's PC did you make sure to install adb/fastboot and drivers: https://forum.xda-developers.com/showthread.php?t=2588979
And make sure to run the cmd shell as administrator/root? (right click cmd, click run as admin)
Will double check everything
Will double check all of those pointers over the weekend and report back. Thanks
Success at last
Went onto my wife's computer and deleted all that I could find relating to SDK and Motorola. Re-installed adb tools and the Motorola drivers and now adb devices return the details of the connected phone. Onto the next stage of unlocking the bootloader and then rooting. Thanks for the help.
After moving to Lineage 14 from stock 21s, I came to realize Android Pay will not work if the bootloader is unlocked.
So I went to go and lock the bootloader (with TWRP and Lineage still installed) and for some reason when I do a "adb devices" the phone is not seen.
I uninstalled the driver, reinstalled.
Tried unplugging, launching ADB, then plugging in..
Plugging in then launching ADB...
Then i put ADB on my wife's laptop (A PC I have never plugged the leeco pro 3 on to), then plugged in for the first time already in fast boot. Still no dice.
Anyone have any ideas?

That is what I am doing, but I am still concerned about the ADB not seeing the phone in fastboot mode. If I have some type of catastrophic issue where i need to restore from fastboot i will be screwed.

If you boot into fastboot mode (Volume Up + Power), does the phone show up in 'fastboot devices'?
If so, then IMHO you should be fine in catastrophic situation.

No, that is the issue, lol
Do you have adb drivers, and did you try completely deleting your device drivers from Device Manager, then reinstalling them by plugging your phone in via USB Debugging? Are you using the platform-tools package? Did you connect via USB Debugging, and did you authorize the computer (the message should pop up on your phone)? I can't fathom why your phone wouldn't be recognized...

Yes to everything, lol
And when I am connected to the phone while in the OS, ADB works fine, shows in when I "ADB devices"
Where'd you get your phone from? Banggood, Geekbuying, Gearbest? Did it come with a vendor ROM? Did it not pass SafetyNet on the original ROM it came with?
Are you following these instructions? Of course, replace the required stock ROM with the one for your version (x720 or x727). So does the issue come up when you reboot the phone via ADB while in the OS?
In any case, try asking on the http://www.leeco.re/ forums as well.
Hi,
I am trying to unlock Google Camera using this guide. It needs me to use the fastboot mode in my ASUS Zenfone Max Pro M1. As far as I can see, I have followed the guide pretty well.
Enabled debugging mode on the phone
Downloaded the adb and fastboot files
Am using cmd with admin privileges
adb drivers are installed
checked connectivity with "adb devices" command and it is showing the serial number
However, none of the fastboot commands seems to be working for me.
As soon as I try to run the command from guide, mobile just goes dark with one line saying Press Any Key to shutdown. Also, if I try
Code:
fastboot devices
command at the CSC Fastboot Mode screen, it just shows
Code:
???????????? fastboot
and goes to the press any key to shutdown. When I try the command to enable the camera, it shows
Code:
fastboot oem enable_camera_hal3 true
...
FAILED (command write failed (No such file or directory))
finished. total time: -0.000s
The build number is OPM1.WW_Phone-15.2016.1901.339-20190108.
Any help is greatly appreciated!
Regards,
pallups
The exact same happened with me. I tried everything but nothing worked, I even tried every single driver and ADB version out there. I only got it to work when I tried to do the same thing on another computer, and it was successful in the first try. Good luck, I hope you manage to get it working!

I agree. I'm using command prompt not PowerShell. So that shouldn't be an issue.
I don't have a second PC. Any idea on how to solve this on my existing one?
I also used CMD. You could try uninstalling every single android related driver, adb program, file, etc. If it doesn't work, probably, only another PC would do the trick. Also, try another USB ports, and make sure you are using the original USB cable that comes with the device.
If you uninstall everything, make sure you install "15 seconds ADB first", then, plug the device.
Go to your computer BIOS Setup and change the USB port to 2.0 and use the original USB cable.
Let me help you.
The problem is the driver.
Shut down your phone, and go to fastboot mode.
Connect to your PC.
Then, open device manager and see "other devices"
There must be an exclamation mark, update the driver and select manually (let me chose from your computer).
Select the fastboot driver, install.
Voila.
You now should be can use "adb devices" command on cmd or powershell.
Sorry for bad English
I found a workaround solution. Use a multi port USB hub regardless is USB 2.0 or 3.0, connect Android devices to USB hub and USB hub to PC. The problem shall solve regardless of how many times you run "fastboot devices"
