Have Honda Accord X 2019 Have 8 inch for based on android 6.0.1 Find how on USB debugging find how on adb mode. Now have problem: when I enter "adb devices" the command on the computer. I get a response device number and that the device is not authorized. I would have to confirm on the device usb debug but I think that Honda blocked. I try in Ubuntu Insert key files from your phones that passed authorization. nothing helps. please tell me what else can be done. you can simulate the situation on any phone just by request do not confirm usb debug and try to do something after the command "adb devices".

Try this:
1. Go to the developer options on the phone and click "Revoke USB debugging authorization" if option is present
2. Disconnect device
3. Delete folder %USERPROFILE/.android
4. Re-start ADB server
Code:
adb kill-server
adb start-server
5. Re-connect device
Code:
adb devices
I do this dont help. "unauthorized". You can verify this in your phone just dont confirm usb debuging when ask.

That your problem, you have to confirm when you connect your device, also make sure u use the latest version of adb, it can be downloaded here: https://developer.android.com/studio/releases/platform-tools
Problem i cant confirm on phone. Need use adb without confirm on phone
Re-create RSA keys
Code:
adb kill-server
adb keygen %USERPROFILE%\.android\keys\adbkey.pub

Hi!
How did you solve the problem?

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
MK

"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!
https://www.xda-developers.com/install-adb-windows-macos-linux/
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.

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.
I have Samsung Galaxy Tab S2 that I attempted to root earlier today. I used Odin and CF auto root method. Everything appeared to go fine, until it restarted itself after it was done. When it booted back up, the WiFi was not working. When I turn it on, it is simply stuck on "Turning on...." and nothing happens.
Problem 2: When I connect the tablet to a computer via USB cable, it does not recognize it. I'll hear a chime, so it detects it, but it does not show up in the file explorer. The tablet is set for a MTP USB configuration.
I tried a factory reset, but that did nothing.
I'm not sure what to do now. I do have a micro SD card, so I'm able to move it back and forth from the tablet to my PC to install APKs and other files. I'd like to try flashing a custom ROM to see if that fixes it, but now I'm not rooted. I used the SD card to install a couple of the one click root apps, but they were either unsuccessful, or require an internet connection to use.
I don't know if it's possible to actually install a custom ROM on a device that doesn't have internet access and can't use a USB cable.
If anyone has suggestions as to either of my problems, I'd love to hear it, because as of now I can't do anything with my tablet.
You can try to:
wipe data/cache from recovery and reboot it again to see if the wifi error still exists, or you can flash it again.
You can get and use adb/fastboot, if you haven't already, and check if fastboot (execute fastboot devices in cmd) recognizes your device after the chime sound. If you're lucky and your device is displayed, you can flash it again. All the best!

Thanks. Executing "fastboot devices" returns an empty list, however "ADB devices" returns some sort of serial number with "offline" next to it.
edit: I've been running adb kill-server and adb-start server commands, followed by adb devices, and that will switch the device status from "offline" to "unauthorized". I'm not sure how to fix that. I navigated to my .android folder on my PC and deleted the adbkey file but that didn't help.
In developer settings Enable USB debugging, revoke current USB debug authorizations and allow your PC's fingerprint. You can also enable OEM unlock in case you plan to play with the bootloader and custom ROMs.
Next in cmd after plugging the device in, check if it gets detected: adb devices
If you get the list you've mentioned, execute: adb reboot bootloader
This should boot your device into the fastboot mode where you have full access to your phone, so be careful what you're doing.
If you need more info on fastboot and adb, check out the forums.
Good luck!

Unfortunately it's still showing the device as "unauthorized". I've toggled developer options and USB debugging on and, and repeatedly tried "Revoke USB debugging authorizations" but it hasn't help. I can't execute the adb reboot bootloader command while it's unauthorized.

Have you been asked for a new computer ID to accept after revoking old ones and plugging the device in again?
As long as you don't add new fingerprint of your computer to the device, your device will be unauthorized.

You need to restock your tablet via odin (to put modem back aka Wifi)
After you restock Install Twrp and install magisk to root, instead of cf-root like you did (this will not breaking the safety net or knox even the modem)
(Note:before install magisk backup your "BOOT" via TWRP)
A friend gave me phone to recovery. His son add a lockscreen and forgot it, now after i turn on the phone
"phone locked" try again after 15270 seconds"
So i try to factory reset from recovery menu but there also got "enter a locksceen password"
Is any way to bypass this, restore to defualt by pc or smth ?
I trying to do wipe from pc, using ADB
but see something like this
C:\adb>adb devices

It's likely that ADB isn't correctly enabled:- the RSA keys dont match this because probably currently used computer isn't same as computer when ADB got enabled 1st time.

Check and uncheck the USB Debugging option in the device. If that doesn't work unplug and plug in the USB a couple of times.
At some point, the device should show a message box to ask you to authorize the computer. Click yes and then the device will be authorized.
I can;t do that, phone is blocked after reboot i got only "Phone is blocked "Try again after 14950 seconds"
But i don't know the pin to unlock it.
i want my phone restore to factory
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

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)
