        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.

          Same when trying access adb when booting phone on recovery after enabling dev mode on?

            @keneda Awesome, so in recovery mode it shows up as:

            List of devices attached
            57489492	unauthorized
            

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

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

                  ADB only works in recovery. MTP should work iirc or use ssh https://docs.ubports.com/en/latest/search.html?q=ssh&check_keywords=yes&area=default

                      @keneda It provides quicker shell access than SSH since it doesn't rely on the local network's strength. SSH appears to have a little lag

                        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).

                          You can check with UT Tweak Tools from open store, in "system" setting tab, "usb settings" "ADB parameter" to see if it is in MTP.

                            @keneda I checked it is in MTP mode. I found someone from 2019 who was in a similar situation:

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

                                @shearflux said in Unable to use ADB on Oneplus 3t:

                                List of devices attached
                                57489492 unauthorized

                                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 am not sure if the 3t has this same issue but the 6t does not have working ADB and you have to use ssh to manipulate the device folders. I can not help other than suggesting to look into it.

                                  OnePlus One with UT OTA-15 daily driver. I would be testing the Halium 7.1 port if I could roll back to OTA-15

                                    ADB only works during the installing process that is the only time I have seen it work (this is the same on a few devices now). 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.

                                      @keneda Sorry for the delay, but I tried the instructions above to no avail 😞 . My feeling is that it's related to the authorization pop-up just for some reason not popping up.

                                        @lakotaubp ADB seems to be the method of choice during any tutorials on various things. I also had it working on my 3t in the past, i'm just not sure why its not working anymore
