Hi, I have a Xiaomi phone with the 3 buttons apparently broken.
I'm trying the adb commands to power up the phone, but unfortunately I don't have the adb enabled on the device (infact when I try to use the command "adb reboot" the system gives me the message "device unautorized").
do anyone knows how to use the adb commands to enable the adb on the phone to power up again?
thank you very much (I'm so depreeeeessed)
ADB ( read: ADB daemon ) is part of Android OS.. Thus it should be obvious when Android isn't running you can't run any ADB command where it doesn't matter whether USB debugging got enabled or not.

Hi!
I have RN2 with MIUI 16.6.7.0 with root access.
ADB v1.0.32
Win 8.1
If I run "adb devices" when phone is running system, I get response "s/n device" as I should. But when I boot phone to recovery (MI-Recovery 2.0.1) I get "s/n unauthorized".
I have tried rebooting PC and phone, disabling and enabling USB debugging, deleting adbkey and adbkey.pub on PC (only instance was in users/user/.android/), revoking USB debugging authorizations, changing USB ports. Nothing.
The last thing I did:
1. reboot phone to system.
2. developer options > turn developer options on/off > turn debugging on/off <> Revoke USB Debugging Authorization
3. reconnect phone to PC
4. was asked: RSA key fingerprint + always allow from this computer > OK
5. run "adb devices" gives "s/n device"
6. disconnect phone
7. power off phone
8. phone to recovery
9. reconnect phone
10. run "adb devices" gives "s/n unautorized"
11. disconnect phone from USB
12. run "adb kill-server"
13. run "adb start-server"
14. reconnect phone
15. run "adb devices" gives "s/n unautorized"
I guess something is wrong with recovery mode on the device. Any ideas?
Thank you

+ run "adb shell" gives " 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."

"On the device, vendors public keys are installed at build time in /adb_keys. User-installed keys are stored in /data/misc/adb/adb_keys."
On my device user-installed keys are stored in /data/misc/adb/adb_keys. The only other instance of adb_keys is /bin/adb_keys. If it has any relevance.
You need to check in the device the popup, the device ask if you want authorize your computer for connection with adb, remember you need to enable adb debug first with push 7 times on miui version into about device.
In recovery adb isn't available you can enable only the adb transfer from the advance menu.

Hi!
Thanks a million for your reply. :good:
I did all that already in steps 2, 4 and 5 and it worked. My problem is adb in stock recovery mode.

Damn I have much to learn (hundreds of pages in a few days and I still dont know anything . So stock recovery doesn't come with ADB access and I am trying to do something that can not be done? ClockworkMod recovery for example should have ADB support if I understand correctly?
I also have that proble my device not connected to phone what I do tell me..

If problem is PC <> phone then install drivers for your phone on PC.
Or describe your problem better.

Downloaded and installed ADB. Following tutorial here:
https://www.xda-developers.com/nexus-6p-bootloop-fix/
Specifically:
- Connect your smartphone or tablet to your computer with a USB cable. Change the USB mode to “file transfer (MTP)” mode. Some OEMs may or may not require this, but it’s best to just leave it in this mode for general compatibility.
- In the Command Prompt window, enter the following command to launch the ADB daemon: adb devices
- On your phone’s screen, you should see a prompt to allow or deny USB Debugging access. Naturally, you will want to grant USB Debugging access when prompted (and tap the always allow check box if you never want to see that prompt again).install adb
- Finally, re-enter the command from step #6. If everything was successful, you should now see your device’s serial number in the command prompt. Yay! You can now run any ADB command on your device! Now go forth and start modding your phone by following our extensive list of tutorials!

I did all the above. But don't see anything from:
C:\ADB>fastboot devices
C:\ADB>fastboot flash boot 6p48C.img
< waiting for any device >
Nexus 6P was plugged into the USB cable on Win10 machine. Am in MTP mode. Most recent Google USB drivers installed.
I have done OEM Unlock in setup|Developer options. I have also turned on USB debugging in same options.
I am [obviously] lost. Anyone know what else I might try?
OK, I have made a little progress messing around on my own. It seems that running from the CMD line in Win 10, ADB command works but Fastboot does not. WHY? Bith are in the same directory.
If I type Fastboot by itself, then I get a list of the associated parameters, which means that the CMD system DOES recognize the Fastboot command.
Now, if I run CMD====> "ADB devices", it looks like my device is recognized and attached (that is my serial# below).
But if I try CMD=====> "Fastboot devices", as the instructions require, I get nothing. And if I try to run the flash job via Fastboot, that does not work either.
==================
C:\ADB>adb devices

Wondering if I need to install the Android SDK on Windows for this process to work?
I Think You need to Redo The process from Step One.
I Heard about This and Never Did An OTA.
If it Persists Try Using A Different PC and If After That It doesn't work Then Yes Android SDK is The last Option.

Solved. I needed to add the ADB install directory to the environmental path. Don't quite understand why, but doing so allowed me to get the problem fixed.
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 Friends,
I have recently Purchased an Oppo F15, I have enabled developer mode, OEM Unlocked, and USB Debugging, with the latest adb drivers installed on my PC.
while I am running the command "adb devices" it returning with the device name I have connected i.e. Oppo F15 but when I am running the command "adb reboot fastboot", "adb reboot-bootloader", "adb reboot bootloader" the device reboots but not going to fastboot, it just reboots in normal mode.
Please help me if I am missing something in this. My device is running with Android version 9.
@Venomiest
Try this commands sequence
Code:
adb reboot
adb devices
adb reboot bootloader
fastboot devices

The bootloader is blocked by code combination. If you try to see more attentive you'll notice the tiny message on the black screen while rebooting.
Not Working

I just got a new F(x)tec Pro-1X and I want to root it. I'm following the instructions to use Magisk from the F(x)tec team which involves 1) installing Magisk, 2) connecting adb and authorizing, 3) adb pushing the Pro-1X boot.img, 4) Running Magisk and patching the boot.img, and 5) downloading the patched .img.
Then I run "adb reboot bootloader" which leads me to a screen where I can choose Recovery mode and then I get to an Android screen that says "No command". I believe it's here that I'm supposed to run "fastboot flash boot magisk_patched-25200_HsxJg.img"; however, when I run "adb devices", I get unauthorized, and trying to run fastboot anyway fails:
$ adb devices
List of devices attached
8ce396c8 unauthorized
$ fastboot flash boot magisk_patched-25200_HsxJg.img
< waiting for any device >
I found elsewhere that from this screen, I can hold the power button and press the volume up key and then release both and I see the Android recovery screen. Then I scroll down to Enter fastboot and press power to enter that and I see fastbootd, but I get the same "waiting for any device" output if I try the fastboot flash command here.
If I go back to recovery mode, and instead go to Apply update from ADB, I then see the following from adb devices, but I still can't run fastboot flash:
$ adb devices
List of devices attached
8ce396c8 sideload
I'm running the latest Android Studio and platform-tools on a Lenovo X270 running Fedora 37 and Linux kernel 6.0.17. I'm connecting using a USB-2 port without a hub and tried multiple USBC cords.
A commenter on the F(x)tec forums said that he could never get his Lenovo X250 to work and he had to buy a Raspberry Pi 3 model B.
Are there any alternatives or diagnostics I can run to help solve this "unauthorized" error?
Did you enable usb debugging in the developer options and validate the box after connecting with a USB cable?

Yes. That was required for steps 2-4 for pushing and pulling the image. When I did that, I had to authorize my laptop on my phone. There's no such dialog during recovery mode. Is there some way to pre-authorize recovery mode with my laptop, or otherwise disable this authorization?
Option below USB debugging, which is: Revoke USB debugging authorizations.
or
read this:
ADB Android Device Unauthorized
Since I reinstalled Eclipse (simply deleted and downloaded it again) I can't debug my applications on Samsung Galaxy i9001 (with CyanogenMod - Android 4.4.2). It worked fine before reinstallation.

Thanks, but none of that worked. My problem is authorizing during recovery mode, not during normal operations. It seems what I really need is to either modify /data/misc/adb/adb_keys on the device, or run adb disable-verity, or set ro.adb.secure=0, but I don't have permissions to do any of those.
It's interesting that another F(x)tec user says this works with a Raspberry Pi, and also says it does not work with his Lenovo X250 running Linux, which is similar to my laptop. This suggests there's some sort of limitation or additional security related to the Linux kernel 6.0.17 and/or Fedora, but I can't find what that is or how to diagnose it. I don't have SELinux running on my laptop.
Good day,
I'm use adb tools from my fedora 37
Your issue is related to how you call adb.
Try this:
adb kill-server
sudo adb start-server
sudo adb devices
The same game with fastboot tools
Its works perfect with selinux on

Doesn't work:

For reference, attached are pictures of all the places where I try the commands and they fail.
I bought a Raspberry Pi 3 B and microSD, installed Raspbian, installed adb and fastboot, connected to phone (normal boot), authorized the Pi, ran adb reboot bootloader, entered recovery mode, phone goes to "No command" screen, but then I get a popup on my Raspberry Pi desktop that says:
Unable to open MTP device "001,013"
Clicked OK and ran adb devices, and I'm back to the "unauthorized" status and adb and fastboot don't work. Tried this in the Raspberry Pi as both a normal user and root (with adb kill-server in between).
Tried with another USB C cable and got a similar error, although it ended with "001,016".
Any ideas?
Resolved by running fastboot on the START screen! (And worked through my X270)
