Nexus 7 2012 bricked, adb/fastboot connection ok but unauthorized. Can You help? - Nexus 7 Q&A, Help & Troubleshooting

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.

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.

I'm in a similar situation. I was asked to use latest CWM. I happened to use Tenfar's CWM that came with the boot loader unlock.
I haven't tried it yet. Will give a shot this weekend
Hi!
I'd suggest the following:
1. Install ADB from the Android SDK.
2. Turn on Settings -> Applications -> Development -> USB Debugging.
3. Connect your phone to a computer. (If you do not have a cable, have it connect to the same local network.)
4. Select 'Motorola Phone Portal' as connection method.
5. Reboot while holding Vol. Down.
6. When you see 'Fastboot', tap Vol. Down until 'Early USB Enumeration' appears.
7. Press Vol. Up.
8. Go to a command line where your ADB executable is.
8a. If you have connected by network, find out your device's IP address and type adb connect <IP>
9. Type adb wait-for-device
10. Type adb logcat
Now, Android's system log should appear. Scroll up and carefully look for error messages - the cause for this could be widely different, I had the same problem with 'Error: ID mismatch' or something along those lines. It is likely that the application itself is the problem, and that uninstalling it will fix things. If you come to that conclusion from the log:
11. Terminate logcat (Ctrl+C, usually)
12. Type adb shell
13. Type cd /data/app
14. Type ls *gapps* (If that fails, type ls and look manually)
15. Take the file name for Gapps' .apk and type rm <filename>
16. Reboot
17. Rejoice
Sincerely,
V

I can't turn on my phone, or DO ANYTHING with it, the only thing is that I get "M" screnn taht's all, if i want to turn it down I hae to do a battery poll.
Excactly, that's what Early Enumeration is for Usually, USB is loaded when the OS is up, I suppose - at least you can't normally connect with ADB during boot. However, with Early Enumeration set, you can connect while the phone is still booting and access every capability ADB or the shell is able to provide. (Granted, uninstalling the .apk in question with adb uninstall did not work for me, that's why I posted the manual approach, but that may have been an error on my side.)
I wonder if my issue is the same. Mine is stuck in a 'dual core' reboot over and over.. I can't get into recovery mode or anything. Sometimes I hate phones.

[Q] ADB error: device unauthorized and device offline

I'm currently getting some strange errors while trying to control my N4 over adb.
http://prntscr.com/1km24i
On Ubuntu I get "device unauthorized" and on Windows 8 I get "device offline".
Same thing happens over USB.
Any idea?
PS: I'm currently on 4.2.2. I where on 4.3 yesterday but installed 4.2.2 again after some strange errors.

As the message have stated, you need to allow the adb access on your phone.
You need to first connect the phone to your PC with USB cables, then the authorization message will pop out on the screen. Tick remember your choice, then allow it.

I'm not getting any message.
Maybe because I already authorized my pc before. A few weeks ago adb worked just fine.

Remove /data/misc/adb/adb_key, reboot your phone and try connect again. The message should come up.
Perfect, worked. Thanks!
I just got my phone back from LG (the mainboard "Fried"). I have the new update pushed to the phone. I have to re-root the phone now as its basically a new phone.
I am getting the Device offline as well message in ADB. As I don't have root, how can I fix this error? I can't navigate to that particular directory. I had no authotization message show up on my computer when I plugged the phone in for the first time... so not sure how to get past this...

This shouldn't be happening on new phone, because the key won't be created if you haven't authorized it.
Can you check your adb version? Try updating it with android sdk manager.
I am going to try and re-download the ADB SDK. I think it's an issue with whatever version I downloaded. I've tried to run the ADB Manager.exe and nothing happens. Currently flying to London so it will have to wait until I get back. Nice of LG to fix my phone and they didn't charge me a dime. Although I did lose everything.
Hello,
I'm having the same problem "Please check the confirmation dialog on your device", but there is no such dialog on the device.
Things I tried and DID NOT SOLVE:
1) Remove /data/misc/adb/* - Failed, there was nothing there (full wipe before flash a new rom)
2) Try different ROMs - Failed, tried AOKP Milestone 1 and 2 and CM10. Dialog never showed up.
3) Try different usb cable OR usb port - Failed, adb is recognized, but no confirmation dialog on the device (device shows as unauthorized)
4) Removed all drivers and installed them again - Failed, same problem;
5) Updated android-sdk (or full delete and reinstall [remembering to adb kill-server]) - Failed, problem continues even with platform-tools up-to-date.
6) Removed all folder C:\Users\Myself\.android - Failed, it was never recreated;
7) Tried to connect via adb over wifi, device is found but unauthorized persists;
Things that gave me some clues:
1) Reboot to recovery mode allowed me to use ADB without any authorization (only while in recovery);
2) Recovery sideload works without any problem;
3) HOWEVER, when connecting to another computer (Windows XP, fresh install on a virtual machine), dialog appears and adb works!
The scenario:
1) Devices tried: Galaxy Nexus / Galaxy S3 I9300
2) ROMs tried: AOKP (4.2.2) / CM10 (4.2.2)
3) Windows 7 x64
The problem is on the computer side, that's a fact. However, I would like to SOLVE it without having to reformat my computer, or change my OS.
Where to start?
Thanks!

After removing your .android directories, you need to restart the adb server to send fresh credentials to the phone.
First unplug the phone from your computer, then run:
Code:
$ adb kill-server
$ adb start-server
Now plug your phone back in and you should see a dialog on the device asking to confirm new credentials for your computer.
After confirming the credentials you should be able to connect to your device.
I hope that this helps...

I know that this post is old, but I came across the same problem while attempting to root my Galaxy S4 today. This ended up being the solution:
1. Grant yourself root access on the PC that is running adb
2. Remove RSA Keys:
rm /home/username/.android/*
3. Restart adb server:
adb kill-server
adb start-server
I hope that this helps.
SOLVED!
I guess I should have read the previous post before I posted this but anyway maybe this helps.
I had this happen to my Verizon Samsung Galaxy S4 SCH-I545 running 4.3 (VRUEM2K) after I rooted using saferoot, then removed the SuperSU app using SuperSU's so-called "safely unroot" menu option. It will no longer request the RSA key from the Ubuntu system I previously authorized (and used to root) and won't re-root using saferoot or motochopper. But since I dual-boot Windows 7 (I hardly use it, came with the laptop), I figured I'd give Odin a try and re-flash it to stock which didn't do anything to the "custom" flag and I still got "unauthorized" in adb in Ubuntu, but I noticed it does show up fine with adb in Windows. I tried the windows verison of saferoot and it was able to re-root my phone and re-install SuperSU just fine. Phone still showed "unauthorized" in Ubuntu.
After posting this I saw the previous comment saying to rm -rf ~/.android/ in Ubuntu. I also cleared all previously authorized computers and disable dev mode on my phone, rebooted, turned dev mode back on, rebooted again. Not sure if this helped, but I went through the following steps as root:
[email protected]:~# adb kill-server
[email protected]:~# adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
15506b89 unauthorized
At this point I pretty much said "F it, not gonna work" and walked away to get a snack, leaving my phone plugged in. I was only gone a couple minutes and when I came back, the RSA authorization request had popped up on my phone. I checked the box to always allow this computer and authorized it. Then SUCCESS, as seen below:
[email protected]:~# adb devices
List of devices attached
15506b89 device
Removing the .android directory seemed to do it, but you need to wait a few minutes for the computer to re-request the RSA key.
after a week of searching. I NEVER KNEW it pop to accept to authorized. WOW cant believe it... after reading this thread im lol'ding right now.
I had tried to kill adb etc but keep saying aunauthorized. solution was to reboot my phone with usb connected,after boot it the dialog to connect appear and my s4 got authorized. backup success.

[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.

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

[GUIDE] Install Windows ADB Drivers for Fire HDs ("Newbie Friendly")

➜ No big ol’ SDK ➜ Latest Google drivers ➜ No messing with inf files ➜ ADB from any location ➜ Drag and drop files
Figured XDA needed a couple more ADB driver guides, so I'm bringing these down from Google drive where they've been getting a lot of use--with no complaints so far. :fingers-crossed:
Follow the steps below to install the Google ADB driver for "normal" (OS) mode.
Follow post #2 to install the driver for sideload mode. You must do this to sideload OS .bin files via stock recovery.
See post #3 for basic info/tips for using the command window and entering adb commands.
[EDIT September 21, 2015] If you're running Windows 10, read this:
At step 3 you install 15 Second ADB Installer. Some Win 10 users are reporting a problem. Please do this to help track it down:
- Be sure to run as Administrator.
- If you get an error, post the exact error and when it happens. Do not rerun Installer until someone replies to post.
- If you do not get an error, please post and say so and tell what type of Win 10 you have (home, pro, enterprise, etc.)
Thanks!
Install ADB Driver for "Normal" (OS) Mode
This uses @Snoop05's 15-Seconds ADB Installer. It provides the driver and software you need and puts the path to adb.exe into your PATH variable so you can run ADB commands from any folder.
Before you begin:
(1) Turn off anti-virus software
(2) Disconnect other physical devices that use adb and shut down any virtual ones. This can go very smoothly if you're not running anything that uses adb, including emulators, some photo-sync software, Gatesjr debloater, etc.
1. Make sure adb debugging is enabled on the the device. (Settings->My Device->Developer Options: Debugging)
To open Developer Options: In Settings -> My Device, tap on the serial number until Developer Options appears at bottom of screen.
2. If you've never connected Fire HD to computer, connect now and read this:
a. You may see a USB debugging message on tablet, tap "Always" and "Allow."
Even if you don't see message, Windows should try to install generic MTP drivers (not ADB!). Wait until you see success or failed message.
b. Unplug/replug and wait for Windows Explorer OR for message that prompts what to do when device is connected and choose Open window to Display Files, check Always do this and then OK.
c. Disconnect..
3. If you KNOW there’s no adb driver installed for the device, go to next step.
. . . If driver might already be installed, do hidden steps.
Connect to computer, open Device Manager (instructions below) and see if a driver is listed under Android Device.
- If a driver is NOT listed, go to next step.

If you see an ID followed by “device,” the driver is installed correctly. DONE!
If you see an ID followed by “unauthorized,” look at the tablet for “Allow USB Debugging?” message and tap OK.
If debugging message disappears before you say “OK,” unplug/replug tablet to see it again.
Repeat the adb devices command and confirm it now looks like above. DONE!
If you do not see an ID, the driver may not be correctly installed or USB debugging might still be disabled on your tablet. Verify all connections and reboot tablet and PC and repeat this step. If adb devices still doesn’t return an ID, follow this guide from the beginning again.
Install ADB Driver for Sideload Mode
Windows can’t recognize the Fire in sideload mode until you install the driver for it.
Note: These steps are pretty much identical to Post #1. Refer there for illustrations.
1. Connect the tablet to the computer and put it into sideload mode, like this: Reboot to recovery, use the volume buttons to highlight “apply update from ADB,” and press power button.
To reboot to recovery:
- From CMD window, run: adb reboot recovery
or
- Manual: (a) Power off the Fire. (b) Hold the power and volume-up buttons until Amazon logo appears, then let go.​
2. Open Device Manager, find KFARWI under Other Devices, right-click it and select Update Driver Software.
If you don't see KFARWI under "Other Devices," see hidden text.
When KFARWI isn't under Other Devices, first be sure you "clicked" Apply Update from ADB on tablet to get into sideload mode.
If you did, see if "Android Device" is listed at top of Device Manager with a driver under it.
If Android Device is not listed, unplug/replug the tablet and see if KFARWI shows up under Other Devices. If it does, go to step 3. If it doesn't, post the problem.
If Android Device is listed, open CMD window in folder containing adb.exe and run adb devices command
- If adb devices returns an ID, this driver is working and you don’t need to install a different one.
- If adb devices does not return an ID, in Device Manager, right-click the driver, select Update Driver Software and go to Step 4.
3. Press Browse my computer for driver software and then Let me pick from a list of device drivers on my computer.
[See “Select your device’s type”]
4. Click Android Device.
[See "Select the device driver you want . . .”]
5. Select the same driver you use for “normal” OS mode (post #1, step 10) and press Next.
6. Click Yes at warning screen.
Driver is updated!
7. In CMD window, run adb devices command and confirm you see your device ID and "sideload," like this:
8. DONE! Issue the sideload command or reboot to exit sideload mode.
Note (shouldn't happen, but . . . ) If you don't get a device ID and you had a driver installed at step 2 and updated it, you'll have to uninstall the driver.
In Device Manager, right-click and uninstall the driver under Android Device.
Restart computer and reboot tablet (to get out of sideload).
Go into sideload mode, right-click KFARWI under Other Devices and see if it has Update Software option.
- If YES, update the driver.
- If NO, reboot once more and go into sideload and you'll have Update option. Update the driver.
Info and Tips for Using the Command (CMD) Window - for "Newbies"
Here's some basic info for using the CMD window and entering commands found in the guides.
Open CMD window
Hold down the shift key, right-click an empty space in an open folder (including desktop), and choose "open command window here"
Give commands on-the-fly
If you used 15-Second Installer (post #1) you can open the CMD window from any convenient location, so you can easily give adb commands "on the fly."
Example: Open CMD from desktop and run adb devices to confirm adb recognizes your Fire.
Install an app (or sideload a bin file)
Open CMD window in the folder containing the file and enter the command: adb install filename.apk
If you open CMD from a different folder, include the full path: adb install "full_path_to\filename.apk"
Format: If there are spaces in the path or filename, put quote marks ( " ) around "full_path_to\filename.apk"
Drag & drop files and copy/paste commands
To enter a long or complicated command or file name into the CMD window, use drag & drop or copy/paste.
Drag and Drop
Type: adb install <--type a space after "install"
. . . then drag and drop your file into the window. The "full_path_to\filename.apk” will be inserted at cursor.
Copy and Paste
Select the command or long file name and use CTRL-C to copy it. In CMD window, type adb install(space) as above, right-click the top bar of the window and choose Edit then Paste.
Installing drivers for sideload
Is there a discussion or a fix for installing the ADB drivers for sideload using windows 10? I'm not sure if Windows 10 is the issue, but instead of getting KFARWI in device manager, I get MT65xx android device. I've followed the instructions after step 9 several times with no luck. I've tried updated the drivers with the ones mentioned in step 3 but ADB device doesn't list a device. Any suggestions?

Sounds like you're opening Device Manager while in recovery, not sideload mode. Look at step 1 again: Reboot to recovery, use the volume buttons to highlight “apply update from ADB,” and press power button.
Once in sideload mode, you should see KFARWI.
(I edited OP to make step for getting into sideload more obvious)

I followed a guide to install Lolipop on my device, I managed to get the 15 Second ADB Installer but could only get the 1.3 version to work.
When I try to do it now it states on the device that I need 1.3.2 or higher. The 1.4 download gives me an Access Denied message and installed 0 drivers.

Someone else encountered this with 15 Second installer. Are you running Win10? What flavor (pro, home, etc)? At what point exactly is "Access Denied" displayed with version 1.4.2?
Also, do you have folder, C:\adb or C:\users\username\adb? If yes, what files are in it?
Please let me know these things so I can try to find a fix. EDIT: @MRDirtyPixels I'll post how to update the driver when you reply. Thanks!
Fire HD 6 on 4.5.3
Win7 Ultimate x64
I'm having an issue at "Apply update from ADB". I do not have this option in recovery - only "Reboot your Fire", and "Reset to Factory Defaults".
I've had ADB drivers installed from past projects. Tried it, got this issue. Went back and installed the ADB drivers from the 15 second installer to see if that helped, still have this issue.
Also, at no point is my Fire listed under "Other Devices" - I don't even have that listed as a category. The Fire is always listed under "Android Device" > "Android Composite ADB Interface", so I figured my drivers were all set.
Any ideas would be greatly appreciated.
**EDIT: Should I somehow remove/uninstall all ADB related drivers and software and try again?
You use sideload mode to downgrade to 4.5.3 from OS 5. (It's only an OS 5 recovery option.) Since you're on 4.5.3, presumably with OTA blocked, you don't need sideload. Sounds like your drivers set up right for OS mode. Go root!
EDIT: @jiznon Be sure OTA is blocked. Else you'll OTA update as soon as you turn on wifi to root!

NO! you'll have to turn it off and use wifi to root. Run these commands:

Well, it's the step you do before turning on wifi to root. Notice that first step says that if you're on 4.5.3, get kingroot and go to step 6. So you're right there, at step 6.

Right. I'm still at "Before You Begin:
Install adb device drivers if you don't have them.
Here's an illustrated guide for Windows drivers. Install driver for both OS mode and sideload mode."
Wanted to make sure I don't miss anything. Looks like I'm on the right track. Thanks!
**EDIT: Everything went smooth. Thanks everyone!
Hi DoLooper, I'm currently following your [Root] OS 4, 5.0.n and Install Lollipop & Gapps ("Newbie Friendly") guide to root and update a Fire HD 7 and that's how I got here. I have successfully completed this guide, but only after I solved a problem that I ran into along the way. I solved it myself, so I want to share how I did it.
I had a Samsung phone before, had Samsung Kies (bringing along drivers) and "Minimal ADB and Fastboot" installed. I had removed all of these and all traces of them I could find. But when I got to step 4 of your first post in this guide, it always asked whether I wanted to install a driver with the name "Google, Inc. SAMSUNG Android Phone". I was worried the driver might be set wrongly in some way and I would brick my Fire tablet during the rooting process because of that (possible?). I continued anyway and after the driver installation finished, it didn't refer to the Fire as a Samsung device in the device manager anymore and the other steps in this guide were successful as well. So I guess I'm safe now.
However, I do have to add that when the Samsung drivers from Kies were still installed (I forgot about them at first), the device manager did refer to the Fire as a Samsung even after step 4. So I guess the moral is that you have to clean your system of other Android drivers/software thoroughly and restart first - and only then begin the procedure described in this guide.
Last but not least, thank you very much for spelling everything out step by step, it all seems like a doable task now.

This is helpful and I'd like to add it, but I'm a little confused. Step 4 is just installing the 15-second Installer software. I don't think it asks anything. Could you please clarify the step where you got that prompt? Also, when it was listed under Samsung, you were able to right-clicking and choose Update and install the google drivers, right? Thanks.
Well, at the end of step 3 the program 15 Second ADB asks "Do you want to install device drivers?" and then a windows prompt appears. This is when I got the following prompt on top of that (only have it in German, sry): imageshack.com/a/img911/8983/bBg2q0.jpg I assume it's some kind of driver, as 15 Second ADB calls it. Is it really specific to a device?
As for your second question, if I remember correctly I was able to do that (I had to dig for it like you explain in step 9 after ". . . If Android Device is not listed, look here."). But afterwards it was still displayed as a (fully installed) Samsung portable device in my device manager. No chance I would go ahead and root from there. That's when I found and removed the Samsung drivers which came with Kies, rebooted, and started the procedure from the beginning.
ADB not cooperating
Ok. I am on a Fire HD 7 Gen 4 at OS 5.1.1, and attempting to downgrade to 4.5.3 for rooting purposes. (My eventual goal is to get CyanogenMod or another 'pure android' ROM on it, if you can help with that, great) When in sideload mode, Windows doesn't detect my device at all (no KFARWI or any other 6-letter combo) but ADB can detect it in both sideload and OS mode. My problem is this: Whenever I attempt to flash a .bin stock recovery, adb stalls for about a second, while on my Fire I only see:
Now send the package you want to apply to the device with "adb sideload <filename>"
Finding update package...
Opening update package...
Verifying update package...
before the device reboots. On adb I then see: "failed to read command: connection reset by peer" Any subsequent attempts without a manual reboot into sideload mode just instantly time out. I have a feeling this has something to do with the weird reboot, but how do I prevent it?

OnePlus 5 fastboot won't recognize in Windows 10

Y cant i get fastboot drivers to read in Windows 10. I have updated the software to the latest update. Developer options are turned on. USB configuration is set to file transfer. In a regular state Windows 10 readds the phone and I can access the contents of the phone. I opened a power shell (regular and as admin) I typed "adb devices" it reads. (I have enabled advanced reboot.) I use the command "adb reboot-bootloader" in boots to fastboot. Now it loses connection. I Open the Run dialog box by pressing Windows Key+R. Type “devmgmt.msc” besides Android is a yellow triangle, then click Update Driver.A new window will pop up. Select the ‘Browse my computer for driver software’ option. I copied the drivers from the OnePlus 5 folder. Try to install but nothing. This is where in stuck. Please help. Thanks
