[Q] Working with ADB & Fastboot

Has anyone gotten this to work? When I type ADB devices, I get:
Code:
????????? no permissions
I rebooted into fastboot with no luck either. Except now ADB doesn't even pick up any devices. And yes, I enabled USB debug mode and unauthorized sources.
Thanks!

I'd guess you are using an older version of the toolkit. Try downloading the latest SDK and using it to see if that helps (it'll also update to the latest drivers). Good luck.

Which OS are you using (Windows, Mac, Linux)?

Linux - Ubuntu to be more specific.
So I figured out the issue. I rebooted into the bootloader (unplug NP, plug it back in, immediately hold the button located on the bottom of the player until the light flashes), typed fastboot devices and it finally recognized the device. ADB still however did not recognize the device while in the bootloader until I powered it back on. Very strange... Not sure if the order I did things made a difference but I'm able to connect to the interface now.
Hope this helps someone. Cheers!

I had the same issue on Ubuntu. You need to run ADB with sudo...why? I have no idea...but I found a post suggesting it on StackOverflow and it worked...so I'm not questioning it.
Before doing anything below, have you installed adb via apt-get? If so, remove it and just put a link to your SDK manager adb and fastboot in a folder included in your PATH or add the directory to the path, then start a new shell before proceeding. The adb and fastboot provided by apt-get are old.
Do the following:
Have your device plugged in and fully booted and with USB debugging enabled
run this command: "sudo adb kill-server && adb start-server"
You should be prompted on the device to authorize the access of your computer via adb
run "adb devices" to make sure that it all worked correctly

Nexus 7 2012 bricked, adb/fastboot connection ok but unauthorized. Can You help?

Hi.
I have a nexus 7 2012 edition which turns on with The Google written logo and under the screen with a padlock. After that it will be in bootloop with a black screen ( I can see the backlight turning on/off). This is also if pressing the power+volume down combination. Seems bootloader is corrupted. Anyway I installed everything on pc plus I'm using the WugFresh Nexus Root Toolkit and here are some examples which show what errors I'm encountering when trying to flash stock firmware .
Log:
Checking ADB/FASTBOOT Connectivity
adb devices
015d4a5ed8500c01 unauthorized
fastboot devices
There is also a notification popup which tells me:
"An ADB Interface device was found but it was listed as "unauthorized"
-Accept the RSA security prompt and check "Always allow from this computer"
At this point I don't know what to do, can you help me?

Same issue - following
I have the same issue now after trying to flash a kernel to fix the slow charging issue. Following this post for any update.

Hi, Sunil_511...
Bit speculative this, and I can't say for certain if the following solution would work, because I've never had this problem myself. It also requires that your Nexus 7 be in a fully bootable state.
Go to your Nexus 7 Developer Options in the devices settings and tap on 'Revoke USB debugging authorisations'. Tap on OK to confirm. See attached screenshot.
This, theoretically, should wipe the slate clean.
Reboot both your N7 and your PC/laptop and when you next reconnect your N7 to your PC/laptop, you'll be asked to authorise this new USB connection when you perform some action that requires it.
Well, that's the plan anyway.
Good luck?.
Rgrds,
Ged.

Nope, in my case my tab is not booting to recovery or system. The only option is adb and it is showing unauthorized. My last option what i think off is to change the motherboard.

I have the same error and like to follow

Google search is your friend. I found the following two methods which seems to have worked for some people.
1. If you are using OS X*:
Reboot your phone into recovery mode.
Connect it to your computer.
Open the terminal and type:
cd ~/.android
adb push adbkey.pub /data/misc/adb/adb_keys
All done! Just adb shell reboot and feel the power!
*For Windows 10, .android directory is located in your the base of your C:\User\user_name directory.
2. Go to where you have stored adb files, open that folder and press "CTRL+SHIFT+Right Click" and select and click on Open Command Prompt option
Now enter following command
adb start-server (Enter)
adb usb (Enter)
After that your device is no longer unauthorized and you should be able to use any command in your Android Mobile using PC/ Computer.
If these fixes don't work, SEARCH.

thanks buddy, i have tried pushing the adb keys but no luck. I will try tge second option. Will let you know after trying.

No difference still the same

Tried your suggestion.. Which i might have tried eventually from googling.. Doesn't make any difference.

Fixed
After doing all the researches, i had to buy a new motherboard and then replace it. Installed new rom and now using it. Spared about 1400INR for a 32 gig version.

[Partialy Solved] G5 plus rooted, and now cannt use ADB.

Phone is rooted, TWRP installed, (almost) everything is OK.
What is not OK is that now I cannt ADB connect. The "Allow USB debugging" window with the RSA key does not open at all.
Another thing I've noted - the "Revoke USB debugging authorizations" option in the Developer options - does not exist.
Any ideas as to how to solve this ?
I'm using linux (Arch, 64 bit). Another phone (an older, stock Moto G2) connect with ADB without any problem - so this is not a problem on the computer side, nor a USB cable problem.
Thanks.
Ben

Solved (almost).
After more googling I've found a solution on stackoverflow (as a new user I cannt insert a link) :
Code:
Reboot your phone into recovery mode.
Connect it to your computer.
Open the terminal and type:
cd ~/.android
adb push adbkey.pub /data/misc/adb/adb_keys
All done! Just adb shell reboot and feel the power!
Now the G5+ is recognized as a "device" with adb.
It's a partial solution because the "Revoke USB debugging authorizations" option is still missing.
Hope this helps future generations

+1 to this solution. I have a very similar problem on my HTC One M8. No prompt, also missing the "Revoke USB debugging authorizations" option.
Between this thread, a few others, and that same stackoverflow answer, I was able to come up with a couple of solutions:
[SOLVED] ADB 'unauthorized', no RSA prompt, and no 'Revoke USB debugging' option

I'm experiencing this now, except I still have my "revoke USB auth" option under Dev Options.
I'll try the adb push method now...

[SOLVED] No ADB on G5 Plus

Trying to run adb results in the USB notification to cycle off/on on the new Moto G5 Plus. I've tried multiple cables, computers, and a factory reset of the phone (both times with the factory image).
Has anyone encountered such an issue?
Basically, I can enable debugging mode and connect my computer, but the moment I issue `adb start-server` the USB notification on the phone begins to cycle. There is no message to authorize the device or anything. For what it's worth, this computer works fine with another device (as does the other). I've deleted the .android directory and saw no change, too.

I'm confused... What are you trying to do? I've never used that command...

The `start server` command just begins to run the adb daemon. It is run without explicitly issuing this command if you run something like `adb devices`. It's like setting up the environment without actually querying anything on the device.

I tried this just out of interest... revoked all ADB authorizations, rebooted my phone and PC, and connected and did a "adb start-server". It popped up the authorization windows like normal, I approved it and it worked like normal. Subsequent kill-server and start-server commands had no unusual effects either after revoking authorizations or not.

OK, I tried using a different Android SDK (grabbed from https://dl.google.com/android/repository/platform-tools-latest-linux.zip) and now it's working. There must be something about the one my distribution packaged that is broken.
Code:
$ adb version
Android Debug Bridge version 1.0.39
Revision 8.0.0_r11
$ LD_LIBRARY_PATH=$PWD ./adb version
Android Debug Bridge version 1.0.39
Revision 3db08f2c6889-android
Installed as /home/badhat/Downloads/adb/platform-tools/adb

Unable to adb

Been trying to get an adb connection to this phone. I'm on the latest Sprint available OTA (NMJ32F). Have not side loaded the later version. Never rooted.
When connecting the phone to PC, device manager shows "Essential Phone ADB" is working properly. I also tried the Google generic ADB driver. The phone also shows a notification "ADB debugging is connected. Tap to disable".
"adb devices” always returns empty. I am able to adb other devices.
I think the problem is the phone is not asking me to authorize the ADB connection as my other phones and tablets normally do.
Any idea?

Did you get permissions on your phone when popup appears?

No. The phone doesn't pop up the permission question. But I don't know why.

Don't know but as long as you don't give permission you can't sideload

Try the usb driver and SDK platform tools directly from Essential website:
https://www.essential.com/developer/current-builds

I am using the drivers from Essential website. However, I was using the lastest Unified Android Toolkit for the adb command. Looks like it may be outdated, as the adb.exe and it's dll's in the link from Essential website is newer. I will try the platform tools from there and see if there is a difference.
Thanks!

Is USB debugging enabled in Developer settings?
Are you in Fastboot? Did you try "fastboot devices"?

ADB devices returns your device is offline?
