I want to unlock my cousin's tab who recently passed away and no one knows the passcode so after some googling i found that you can do it via ADB.
(https://forum.xda-developers.com/showthread.php?t=2620456)
The device successfully connects with my pc but when I execute "adb devices" it shows;
.......................... unauthorized
and running adb shell shows;
This adbd's $ADB_VENDOR_KEYS is not set; try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device.
With the device locked Im unable to authorize my computer so I decided to search something for that too and found this article where it tells u to pull keys from another device and push it into your locked one while in recovery mode and this is where Im stuck. Whenever Im in recovery mode, adb devices shows nothing so if someone of you could help me would be awesome.

Enabling USB Debugging through ADB? Im Stuck at Black Screen W/ "Unauthorized" in ADB
So I've had a few problems lately, all leading up to my Kindle being Bricked at Black screen after Recovery reboot attempt.
Using ADB, My Device is showing up, however I am getting "Unauthorized" and cannot access any root functions, or push commands to the Kindle.
I'm trying to do a Reset/Brick Fix by flashing the OTA update and start from scratch(Stock), but have no way of doing so via ADB because I can't push anything to my once rooted device, now saying it's UnAuthorized.
Is there an ADB command to either Root this thing, or even just to enable debugging mode via usb without actually going into the system? My System appears to be missing, or not running for whatever reason.
Is there ANYTHING I can do to get this thing up and running again? ADB Is Recognizing the device, but "ADB Shell" is giving me the same Unauthorized error.

Same problem - can't boot into the os so can't enable USB debugging to get to adb access.
adb devices returns the SN with "unauthorized"

error: device unauthorized.
This adbd's $ADB_VENDOR_KEYS is not set; try 'adb kill-server' if th
ng.

that means you havent enabled debuging mode yet. that or you did and you just need to unplug and plug phone back in to get the dialog box to pop up
Hello
I have e Lenovo a1000 mobile phone with a soft brick.
The problem that when i want to access to fast boot with adb
Code:
adb reboot bootloader
the famous message appear
Code:
error: device unauthorized.
This adbd's $ADB_VENDOR_KEYS is not set; try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device.
In addition to that, when i combine buttons (Vol+/- + power) nothing happens.
Please i can't go to phone settings or browse files, the phone turning in bootloop.
Is there any solution to bypass this error?? I'm using Ubuntu OS.
And thanks.
Hi, I'm trying to learn to use adb/fastboot and here are a few random things I ran across I'd like to ask to understand better how it works.
Does adb work only when the phone's on and usb debugging also on or do some commands also work in other modes? Example: phone's off (Honor 6) and "adb devices" doesn't recognize it but all "adb reboot" commands work no problem, why?
Could some adb commands be blocked by the manufacturer? On another device (Prestigio), "adb reboot recovery" works but "adb reboot bootloader" doesn't do anything. Is there a way to safely stopping a running command?
Example: in the recovery mode, I accidentally started the adb sideload and the phone prompted me to enter the full path to the sideloaded file (in the PC terminal); trying to enter a non-existing path didn't do anything, the sideload screen on the phone was still there; holding the power button didn't help; removing the battery would probably do the trick but it's not removable so is there a safe way to stop the command? Maybe adb kill-server?
Hello everyone, hope you're fine,
Unfortunately, I had bad luck and utterly smashed my device display (Samsung Galaxy A72) which has a PIN to unlock the device access.
My problem here is that I'm unable to accept the authorization for adb connection, just can't touch the accept popup (which I suppose is "being displayed" on the broken screen).
There is by any chance, a way to send a touch signal using the adb prompt?
The current status when I try any command except the
Code:
$ adb devices
is:
Code:
$ adb shell
adb: device unauthorized.
This adb server's $ADB_VENDOR_KEYS is not set
Try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device.
In case I can get this resolved, the next steps would be to try to send the adb input keyevent accordingly in order to unlock it by PIN.
Thx in advance to anyone who is able to help
Note: I'm using Linux or Mac, so MS Windows wouldn't help too much.
