HTC Droid DNA Bootloader Unlock App Method (Difficulties)

I have been trying to do this new method to unlock my DNA but im having difficulties getting my computer to recognize my phone. I installed the app and followed directions perfectly. But when i enter fastboot and enter the "fastboot oem readcid" command in the command prompt window it says "waiting for device". I have my phone connected via USB and i followed all directions, i want to unlock and get rooted. Anyone who could help or just tell me what i am doing wrong i would appreciate it very much Thank You.

Yes i enable debugging, and when i get to the fastboot screen and enter the command "fastboot oem readcid" in the prompt window it excepts the command and says "waiting for device" like the PC is not recognizing my phone.

that's why i asked you to do a fastboot devices when in fastboot mode as that would list the devices attached, also are you on mac or windows and if windows which windows version, also please PM a mod and ask him to move this to the DNA q&a section, you'll get more help there.

As soon as I get back to the house in going to do that. But I have a PC with windows xp that I'm using.

[Q] "adb devices" command not listing my Nexus 7 (2013) !

When I try to run the "adb devices" command in the cmd prompt, its is just saying "List of devices attached", but the device Nexus 7 (2013) itself is not been listed. I am able to Kill and start the server. "adb reboot" command not working.
I checked the Device manger; It is listing the device as "Google Nexus ADB Interface" !
Also the "USB Debugging" is checked along with "MTP Device"
What could be the problem?? Any issue with drivers. I have already downloaded the adb and fastboot tools in the drive and running the cmd prompt from that path.

It's driver related, install these, then reboot the PC, then with the device plugged in, delete the Google Nexus ADB Interface from within device manager, delete the driver from system if prompted, and leaving the device plugged in, reboot the device, it should redetect the device properly, wait for it to boot up all the way, then unplug the device and plug it back in, and test, you will want to do this for every mode combination, as per my post found here: http://forum.xda-developers.com/showthread.php?p=50253887#post50253887
The important part is making sure the device is plugged into your PC and set to the mtp/ptp/debug mode you want detected when you reboot the device after deleting the driver from device manager.

Thank you for helping out. I found what was wrong. The drivers were ok. I had ticked the MTP device option earlier. When I ticked the Camera (PTP) instead, the ADB commands started working. I even rooted and installed custom recovery through adb interface.
Thank u once again.

You're welcome, fwiw, if you follow my suggestions, you can make it so adb works in ptp and mtp, but if it's not important to you, then it's not dire.

RSA fingerprint

Hello all,
I have tried on different laptops, with different cables but my pixel c will not show the rsa dialog to allow access for adb/fastboot. I have tried NRT as well but the device cannot be found. The device is running the lastest software version as of 9/18/16

I think more detail is required. Device configured correctly? - Developer options - usb debugging enabled (also revoke debugging authorisations causes a request for RSA confirmation on a previously "connected perfectly" device). Guessing you're using Windows - what "adb" driver (if any) is shown in Device Manager

I've tried to revoke authorizations but nothing happens, and I can access the devices internal storage. However, when I plug the pixel c in, it immediately goes to charging mode and there isn't an mtp button in the storage settings in 7.0 so I can't toggle it on/off. I've also tried enabling/disabling debugging while connected and nothing happens.

I'll assume you have an "adb" driver of some form showing in Device Manager and adb.exe and fastboot.exe in a directory that I'll call "ADB".
Connect the Pixel C and unlock. By default it should have notifications for USB debugging enabled and "USB charging". Adb will work at this stage.
Open a command prompt and change to "ADB" Try the command "adb devices" and it should show your tablet.
Try "adb reboot bootloader" . I expect this command on your PC to fail because it holds no authorisation. But it should trigger:
a) get your tablet to request RSA authorisation
b) start the process of installing the "Android Composite ADB Interface" device driver (under "Android Device" in Device Manager.)
Repeat "adb reboot bootloader" and your tablet should reboot into a "waiting for fastboot command" screen
Try "fastboot devices" should show the tablet and then "fastboot reboot" will restart your tablet.

Pixel c not show up on adb devices list

Fastboot - not devices found in cmd

I'm trying to work out unlocking bootloader, but when I get to the point where device should be in fastboot mode, and on computer I write fastboot oem get_unlock_data command in cmd, it shows "waiting for any devices" and nothing happens. Tried writing fastboot devices, but it shows blank list.
USB drivers are PROBABLY installed with some bugs, I cannot install nor unistall them now idk why, during installation process it shows error "Parameter is incorrect" and then Motorola Driver Installation Utility shows up, which stays at half of the process of scanning drivers. When I choose the "clean only" option, Runtime error shows up at some point. Choosing update driver does nothing.
Any ideas what to do?

turn on your mobile and make this cmd.
adb devices
a window will open on your mobile, check the box and restart the unlocking of the mobile.

[HELP] MI a2 lite Fastboot Exits aAutomatically

I have a mi a2 lite and i want to unlock its bootloader, i have alrready enabled oem unlocking on developer options, when i boot my device in fastboot and connect to computer, command window says waiting for device and after 15-20 seconds of connecting my device to my pc, fastboot mode automatically exits and shows charging animation. Please anyone can help?
My device is in andoid pie (stable).

Check if you have installed drivers and run "fastboot devices" to see if device is recognised.

Agree something with your PC.
Phone will automatically exit fastboot if no connection in timely manner.
Check drivers are installed, reboot your PC.
Also be sure USB debugging is on in Dev option and trust PC.
For me, I generally boot Android normal. Then plug into PC and from command line, "adb reboot bootloader". That should verify adb, If that doesn't work, your PC not talking to device.

I reinstalled the drivers and the command "adb reboot bootloader" works for me that means it boots to fastboot mode but when in fastboot mode, when i enter a command "fastboot devices" it does nothing and when i enter command "fastboot oem unlock" it again says waiting for any device.
i have attached a screenshot of it.

I've tried restarting my pc as well as my phone and after 5-6 attempts it is now unlocked.
Thanks guys for supporting and giving response to my post
Love ya'll

The solution for fastboot disconnecting after a few seconds are the windows drivers. There are different drivers for our phone, normal, bootloader and fastboot. Windows loads these drivers depending in which state the phone is.
If you still didn't find the correct drivers, you should try installing MiFlash, as it contains all the needed drivers for our phone
If you like to try the Linux way, there's a distro called FWUL linux here on XDA

Yeah, just go to windows drivers, click update device driver, browse my computer, let me pick, choose android > next > and choose another version or try whatever you feel is appropriate
