<![CDATA[Unable to use ADB on Oneplus 3t]]>Hi, I've been trying to troubleshoot this issue but have not been able to figure it out. On my Oneplus 3t, I enabled developer mode, and confirmed on the phone with

ls /usr/bin/ | grep adbd

that the daemon exists. Adb is also installed on my laptop, but it cannot find my device. When I use:

sudo adb devices

It doesn't list any device. I am able to transfer files over MTP and am also able to SSH into the phone. Is there a hardware ID or something missing that prevents ADB from recognizing my device? I don't get any pop-up on the phone for me to hit "allow" with.

I also had it working on my 3t in the past, i'm just not sure why its not working anymore

My feeling is that it's related to the authorization pop-up just for some reason not popping up.

Other than that I can/have transferred files back and forth between phone and laptop via usb. I have tried ssh but get a syntax error and need to look into it further from my side.
You do have to keep switching Dev mode on after reboots and restarting but I mention that just in passing.

I can not help other than suggesting to look into it.

For the sake of help, i tried a last thing, i qwanted your problem, and got a ping, see :
https://honeywellaidc.force.com/supportppr/s/article/How-to-fix-adb-devices-shows-unauthorized-device

Possible solutions if "adb devices" shows a device as "unauthorized":
_
C:\Users\JohnDoo>adb devices
List of devices attached
17310D821D unauthorized
_

  1. Disconnect USB between PC and device
  2. Stop adb server by entering "adb kill-server" in command window
  3. On device use "Revoke USB debugging authorizations" in "Developer Options"
  4. On PC delete "adbkey" file in user directory, for example "C:\Users\JohnDoo.android"
  5. Reconnect the device to the PC
  6. Open a command window and enter "adb devices". Watch the device's screen for any Authorization message and allow the connection.

The device should now show as "device":
_
_
C:\Users\JohnDoo>adb devices
List of devices attached
17310D821D device
_
If the above does not help, re-installing adb and or USB drivers may help.

You can revoke USB debugging authorization with UTTT like you probably saw.

Now i must go to work, hoping you succeed ^^

I suppose I'll use SSH for now, but I really appreciate the help!

OK, i understand. I don't know why your device is unauthorized, your phone has a pin, dev enabled and in recovery (and for sure i assume bootloader is unlocked), PC adb drivers and terminal installed, that should work (use USB2 not 3, and good data usb cable).

SSH appears to have a little lag

Does your device is locked by pin code when you shut screen off, then on back?

Which is nice to see. How do I get it authorized?
