Did you try accessing adb while in recovery?
If I type adb devices it says list of devices and its empty..i thought its because I disabled usb-debugging...???

ok tried now and it worked...strange..ok happy anyways...

I have the same problem as I renamed the framework-res.apk file and now stuck on boot screen...
How can I activate the USB debugging mode now if I cant access the settings tab in the GUI?
How can I restore the framework-res.apk ????
Also adb shows no Device?
Please help!!!
Do adb kill-server and then adb devices again, should work.

I can only see one page and I read it completely. Here is description of my problem:
I already rooted my kindle fire, downloaded android market I loggedin using a google account. After that I was unable to change the google account. Browsed web and I saw the post of the video. I followed the instructions in the video.
steps followed: using root explorer, went to /system/framework and renamed framework-res.apk and and after I completed the renaming, the device crashed (or I clicked something; hence crashed?) and stuck in blank carrousel page.
So, I rebooted and all I get now if boot logo of 'Kindle fire'. It doesnt go any forward.
I connected to PC and I am able to see the device in ADB. But no root access in shell. So, any adb command I give I get back errors like: no permission; read-only folder, etc.
When I use the Kindle fire utility v0.9.3 and try to do temp root or root, I get.
Error type 2 android.util.AndroidException: Can't connect to activity manager; is the system running?
adbd cannot run as root in production builds
PC detects the device as 'Android Composite ADB interface'. But cant do anything in adb. I can push files to /data/local/tmp folder. Thats about it.
when I do
adb shell mv /system/framework/framework-res.apk.bak /system/framework/framework-res.apk
I get:
failed on '/system/framework/framework-res.apk.bak' - Read-only file system
Can someone help rename this file back to original framework-res.apk?
Thank you very much;
Oh! by the way, I also have a cable jigged as described in another thread. I plugged in the cable, did adb and the device is recognized. But no root access so all commands come back with permission denied; read-only file system, etc.

First off, you're asking for help on your Kindle Fire in a forum for the GT-I9100. Totally different device...
That said, if you're getting "failed on '/system/framework/framework-res.apk.bak' - Read-only file system", this means your system folder needs to be remounted as read/write before you are allowed to rename or otherwise alter files in the system folder.
You need to do "adb remount" before you do "adb shell mv /system/framework/framework-res.apk.bak /system/framework/framework-res.apk"
EDIT: I'm also confused... Why the heck are you trying to rename framework-res.apk to solve what sounded like an issue with changing the google account attached to the device? No offense, but it doesn't sound like you should have root on your device at all. At least, until you understand what you're doing.
EDIT 2: Alternatively to the "adb remount", can you boot into recovery and rename the file there? I don't know anything about Kindle Fires, but on my I9100, I can boot to recovery, run an adb shell, and have root access to rename /system files once I remount.
But again, since you have a Kindle Fire, I don't know if that will work for you.
Is there a kindle fire forum?

I used root explorer, made a copy of my original and named it original, then copied over another build.prop from my SGSII to play with MC3 and now the prime wont boot.
Im sure I will have to wait until i get home to use my USB cable but is this something I can fix through ADB?
how can i get the Prime into state that ADB can talk to it since now all i get is a black screen after the Eee pad splash screen?
Can you get into the recovery?
yes but it it shows the little android on his back with a red triangle.
is that because im rooted?
see if you can get adb access, if so push back an original build.prop...
note... never ever push a build.prop from a different device.. its the most stupid thing you can do.
yes i feel extremely stupid. i hope i didnt brick my prime doing something this retarded.

i hope so to bro, although i did read someone messed up his build.prop before on his prime, dunno how that went afterwards... u might need to search for that
If you have access to either adb.. or maybe if you can flash zip files from your recovery you're good to go.
Using Adb:
Running "adb devices" should print your Device #, if it prints nothing, it won't work..
adb pull /system/build.prop build.prop.bootloop
adb pull /system/original.build.prop original.build.prop (>> Edited to original.build.prop as per your last post)
Then if you look at the files on your PC..
build.prop.bootloop would be the one you have right now that's causing loops
build.prop would be your backed up working build.prop.original
Then just push the good one:
adb push original.build.prop /system/build.prop
adb pull/push usage:
adb pull remotefile localfile
adb push localfile remotefile
You may be able to go this route and reflash the entire rom if you dont have adb access. From what I understand is you rename the update.zip file to whatever it says in the link to rename to and put on the root of sd card and do the power + volume and go into recovery.

i can get the device into APX mode because i installed the APX driver and when i hold VOl UP and Power, my windows 7 computer shows Asus Prime APX under System Devices and it goes away if i unplug it and vice versa plugging it back in however ABD stil shows Blank for connected devices.
not sure what Im doing wrong so im uninstalling my OLD SDK from last year and reinstalling the latest SDK to see if that helps.
ok so my Prime boots into APX mode according to windows 7 Device manager. it shows APX not greyed out.
however despite this, in CMD when i type ADB Devices it shows BLANK and of course any adb commands return no device found.
if i let the Prime reboot into its Boot loop, then ADB Composite appears in Device manager.
if i go to CMD and type ADB Devices, it always says ADB Server out of date killing server and then it shows Daemon starting and then says Failed.
if i try 2 times back to back i eventually get the Device Serial number.
so then i try PULL command and that works no problem
when i try the PUSH command i get an error that says READ ONLY FILE SYSTEM and it fails.
i'm stuck now

I think its bricked... because from the research Swift and I did on a battery mod, he tried a mod I don't remember what and it ended up in boot loop. ADB won't work because of the boot loop it doesn't stay long enough in a booted state for ADB to send/receive the commands. If your still in your return period try for exchange.

The file system will be read only by default. You need to remount /system as read/wrire.

You need a micro sd and rename a file, easy, poof, fixed.
As far as adb goes
adb remount
or
adb shell
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system

Unfortunately i can not remount the system. if i try to remount it says either device not found or error it can not.
its like it never listens long enough..
for example if i type ADB Devices, it will say "ADB Server out of date killing server and then it shows Daemon starting and then says Failed"
if i try that 2-3 times then it will eventually say Devices and list my Serial number.
if i try immediately after that to go to ADB SHELL, it starts and then i type:
adb push original.build.prop /system/build.prop
as soon as i hit enter it says Device not found.
even if i try that command 5 times in a row hoping that it takes one of the times, it does not.

i cant remount, i can shell but if i do that then it says no devices connected.
wow, i royally screwed things up with this stupid build.prop like an idiot.
For the record, once in adb shell it's not adb push anymore..
That'd be
cp /system/original.build.prop /system/build.prop
I doubt this will do you any good, it seems you just can't stay in adb long enough because it reboots.
You don't gave a working custom recovery do you? (like clockwork mod)
I think I've seen people with custom recoveries on their primes.. that'd allow you to adb properly or flash a zip file with your build.prop..
Also, Did you look at this thread?
http://forum.xda-developers.com/showthread.php?t=1514088
They have a few unbrick solutions and something about getting adb to work from recovery. Recovery wouldn't bootloop while you're trying to adb..

THIS!!!
i downloaded the latest stock firmware .15 from asus support site. renamed it to
EP201_SDUPDATE.zip and copied to a micdro SD card.
held VOL DOWN + Power and when i saw the white text hit VOL UP twice
and the recovery manager detected the file on the SD card and started flashing.
no more RED triangle android anymore.
im sooo excited this worked and will definitely take more caution in regards to the build.prop file. never realized how much of an integral role it played in the android OS.
thank you very much for all your help and to the others thanks for your help with ADB. even though it didnt work, i played with ADB so much last night and today that i feel much more comfortable with it.
I searched the forum but did not find anything related!
I have a Motosmart XT303 - Android 2.3.6.
Somehow too stupid, I just deleted the folder "/system/app" with "Root Explorer"
I have the backup folder, however, the phone obviously went into bootloop.
Is there any way I can use adb push to put the applications folder in /system/app?
-When trying to use 'adb push /app /system/app' it shows me the message "error: device not found", looking for this error, I discovered that it is because the USB debugging, however, I can not even pass the boot screen, is there any way to enable debugging via ADB?
Thank you! awaiting answers.
Hi guys,
EDIT: See the last posts - I have figured this out, and tried to include helpful information, if you are having this problem too.
Firstly please accept my apologies if this has been answered already. I have searched the forum, and the Internet, and cant find specific instructions, or a guide that I can follow with any success.
I stupidly deleted system files from my Kindle, but now I have purchased a fastboot cable, and I'am able to get it into fastboot mode.
I have correctly installed the ADB Drivers, and the device is now recognized by my Windows 7 Device Manager. It shows 'Android ADB Interface'.
I would guess that I need to flash the entire Kindle, but I'm unsure of how to do this, as I cannot seem to access the device at all. It currently loops when booting, giving me no time to see it as external storage via My Computer.
Please would someone more versed in this, guide me specifically through how to get myself back up and running again? I would be forever greatful.
I have SDK and JDK installed, but do not have the knowledge I need to learn how to use them properly.
Thanks so much in advance.

You definitely need the fastboot cable to push files through the ADB Interface dude. You can buy one for dirt cheap on EBay. Then all you do is simply plug it into your PC and Kindle, and it should put the Kindle straight into Fastboot mode.
Then you need to install the ADB Drivers for the Kindle.
From there, I'm stuck I'm afraid.

OK，I think I'm gonna get one and give it a try. the only way to fix this brick is in the ADB Interface I'm sure. though I also don't know How to do.
I've finally figured out how to get ADB up and running, and how to start command prompt. I found this link helpful:
developer.amazon.com/public/resources/development-tools/ide-tools/tech-docs/05-setting-up-your-kindle-fire-tablet-for-testing
If anyone needs help pushing files through ADB, I recommend that link!
Do the following to detect your Kindle Fire tablet through ADB:
Open a command prompt window.
Change directory to your Android SDK platform-tools directory. - To do this, find out where SDK is installed on your PC. Copy the path.
Type cd in command prompt, then space, then paste the directory path. EG, C:\Users\Administrator\sdk\platform-tools
Hit enter, and the command line will change to read C:\Users\Administrator\sdk\platform-tools.
Run the following commands and confirm that the serial number for your Kindle Fire tablet appears in the list of devices.
adb kill-server
adb start-server
adb devices
Then follow the rest of the guide. I think all you need to to do, is push a system update through, by putting the file in the tools folder of SDK. This should make the device update, and put back any critical system files that you had previously deleted.
Now I'm just having issues with it finding the device, so I'm going to charge the Kindle for a few hours, and then try it again.

In command prompt, there is an ADB push command, so I think all you do is type that, then the path of the file.
To list all the commands you can use, change command prompt to your platform-tools folder within SDK, type ADB in command prompt, and it will give you all the options.
You'll need to unzip the update file first I think.

Working with the HDX 8.9.
I think I have deleted some of the system files also. I was reloading a safestrap backup and rebooted but the backup had failed to complete. I don't know what may be missing from the system files and would like to push the system files onto the device.
Right now I get a gray kindlefire screen for about 90 seconds, during which I have adb access, then it goes to the color kindlefire screen and asks if I want to Restore to Factory Defaults or reboot. I finally subjected it to the Restore to Factory Defaults, but that just wiped the cache and data partitions, I don't see where it did anything to the system files. It did not change my adb access.
In adb I can push files to some locations but others say: failed to copy ....: Read-only file system.
I cannot run shell commands
# adb shell
soinfo_link_image(linker.cpp:1617): could not load library "/vendor/lib/libNimsWrap.so" needed by "/system/bin/sh"; caused by load_library(linker.cpp:745): library "/vendor/lib/libNimsWrap.so" not foundCANNOT LINK EXECUTABLE
I was working in Windows 8.1 but have switched to Suse Linux but the results are the same so far.
I have the stock system files but I am not sure how to push them to the device, if it can be done, while the device is trying to reboot.
fastboot
I can put the HDX in Fastboot mode with the adb command. But when I try to pass commands to the HDX I get:
< waiting for device >
and I have to Ctrl-c to stop the process.
Do the fastboot commands only work if you have a fastboot cable???

Its finally here guys, the moment you've been waiting for, ROOT for the Lenovo Tab S8-50. To Root Your Device, All you have to do is enable developer options/mode by tapping on your build number multiple times. Then navigate to Developer Options and make sure you enable USB Debugging or else your PC wont recognize the tablet. Make sure that you have Installed the proper ADB drivers for your device and its Drivers.
Requirements and conditions:
1-Make sure that your computer is not connected to other Android devices
2-Make sure that you have installed the ADB drivers for S8-50 tablet
3-Make sure that the machine is turned on USB debugging
4-Connect the device to your computer via USB
5-Download the below attached file, extract it, and run the program
6-If all the conditions and requirements are met, after working program closes automatically, the device will reboot automatically and will appear on the unit program SuperSU .
Download Links will be provided at the end of this post ! I/we are not responsible for any harm or damage done to your device during the process of rooting it. If it fails and bricks, that's your fault. I've successfully rooted mine and it was easy.
If you get an error during the rooting process that said "adb server is out of date killing adb server didn't ack" or something like that, there is a way to fix it. Open Task Manager on your PC and try closing adb.exe and restarting it, or just Google the error and you will most likely find a way.

6-If all the conditions and requirements are met, after working program closes automatically, the device will reboot automatically and will appear on the unit program SuperSU .
Download Links will be provided at the end of this post ! I/we are not responsible for any harm or damage done to your device during the process of rooting it. If it fails and bricks, that's your fault. I've successfully rooted mine and it was easy.
If you get an error during the rooting process that said "adb server is out of date killing adb server didn't ack" or something like that, there is a way to fix it. Open Task Manager on your PC and try closing adb.exe and restarting it, or just Google the error and you will most likely find a way.

The download isn't working for me. It's not downloading as a zip? Any suggestions?
If youre using windows, download a program called 7-zip and downoad the file. right click the root software and click extract here. or open with 7-zip. You could also use winrar. The format of the file is in .7z right ? that means search up http://www.7-zip.org/
Any idea how to unroot?
Not sure. Have you tried the full unroot method in the su app?

Thanks both of you. I ended up returning it, root and all, but I'm sure your suggestion would have worked.
After rooting, has there been anything anybody's been able to do about battery life? I don't imagine there's been any Roms built for this device yet, but didn't know if maybe someone's figured out something that's helped extend their battery life, because when playing certain games like clash of clans for instance, I'm lucky to get an hour and a half of game play, and that's with my brightness turned all the way down. Any suggestions would be greatly appreciated. Thanks

This root guide works on s8-50f! thanks Xakep
This is a very easy and usefull root instruction, i rooted my tab s8-50f with no problems.
I followed the steps described and got instant root without any issues.
My machin is windows pc with windows 8.1 pro 32bit. Plug your tab and windows recognized the drivers just make sure your device mngr shows lenovo s850 and you are all set. Then just run the flash tool and it will run in less than a minute your tablet will reboot and your tab will be rooted.
Yes this is probably the easiest I've ever rooted any device in the past. If at first it doesn't take, don't worry it will. Just repeat the process till it does. Thanks Hash.h for putting up this thread and passing along the info

Where can I download the ADB drivers for S8-50 from?
I think drivers come with tablet. Try to connect the tablet and it will show CD drive on which is the driver.
error: device offline?
I followed this with no luck. I have adb installed and running "adb devices" shows the tab connected, but when I run the tool "error: device offline" scrolls repeatedly and no root.
Any suggestions?
Thanks
Worked great. Thank you.
Awesome little tablet.

Tried on another computer and succeeded.
This worked brilliantly...
but then I upgraded my firmware using the in-built system and it de-rooted. Now the exe no longer works.
New firmware is S8-50F_S000200_150121_ROW
Exe -appears- to run well, but appears to fail on the last command. Unfortunately it disappears off the screen before I can check the exact nature of the error. It appears to go fine until the final attempt to copy the SU binary into place fails with a 'File not found' error.
I've also tried the other method here:
http://forum.xda-developers.com/general/rooting-roms/guide-lenovo-s850-row-t2927400
The flashtool fails to find the device (I know the drivers are installed), so I'm unable to install the new boot image.
ADB shell fails
mount -o remount,rw /system
with the response
mount: Operation not permitted
so none of the 'push' operations will complete as the /system folder is read-only.
Any suggestions?

Same problem here. Lost root after the last update and now I can't get either root method to work.
After fighting with this for nearly a month and reading dozens of threads on xda, stack-overflow, etc... I finally figured out this issue, so I'm putting it here in hopes it saves someone else the frustration.
The issue presented itself on my HTC One (M8) running the ViperOne 6.1.0 ROM.
I'm putting this thread in the general section though since I've seen many people with very similar, if not the same issues on a wide variety of devices.
I believe the root cause of my particular issue may be the way HTC sets their devices to simply allow all debugging without authorization if the phones are s-off.
Mine is still s-on, but I have another M8 that's s-off with the exact same ROM as well as an s-off M9, and both of them go straight into debugging, no questions asked, no prompt.
I'm wondering if maybe the ROM was developed using a developer version of the phone and is just missing the prompt, or something similar, but this is just conjecture.
The basic problem was that, when I tried to connect ADB, it showed the phone as "unauthorized" and no matter what I did, the prompt would not come up on the phone to allow debugging.
Also of note, I was missing the "Revoke USB debugging authorizations" menu item entirely (I could search for it, but it wasn't actually there in the menu)
I tried many different combinations of changing drivers, USB modes, enabling/disabling debugging, different machines, deleting the public and private keys for ADB on the computer, etc... all to no avail.
Finally, after much research and testing, I found this comment on stack-overflow and figured out how to manually authorize keys.
Note: This will require root, a custom recovery, or some way of writing the the system partition (I used TWRP at first, then TerminalEmulator later)
The key was to understand what clicking the dialog to 'always allow' a machine actually does.
When you click to always allow, android appends the public key from ADB on the computer into a specific file on the phone.
Since my phone wouldn't connect in the first place though, I didn't have that file or understand the format, etc...
The file is called adb_keys, it is a file (not folder) which is located at: /data/misc/adb/
The format of this file is one public key per line.
Thus, there are a couple of ways to go about manually authorizing a machine for debugging.
First, manually building the adb_keys file. (This is what I did at first)
Second, copying an existing adb_keys file from another device (Which doesn't need root)
For manually building the adb_keys file, the first step is to find the public key on the computer.
For me (Windows 10) it was located at C:\Users\<my profile>\.android\adbkey.pub
For Linux and OSX, I believe it is at: ~/.android/adbkey.pub
If you only need to authorize one computer:
Simply copy the adbkey.pub onto the device location: /data/misc/adb/ and rename it from adbkey.pub to adb_keys
chmod 0644 and then reboot.
Now, the phone should accept debugging from the computer just as though you clicked the dialog.
If you need to authorize several computers...
As mentioned, the /data/misc/adb/adb_keys file is actually a list of all the keys which have debugging permissions, one key per line.
First, collect the adbkey.pub files from each computer you want to authorize.
Then, using a text editor which supports linux style line breaks (Notepad++ if on windows) simply create your own adb_keys file by appending the contents of each adbkey.pub file, putting a line break between each key
Now save the adb_keys file you just created, and put it on the phone's /data/misc/adb/ folder using whatever method you prefer, and chmod 0644
If you need to revoke debugging permissions, (like the menu option, if the menu option is missing)
Simply delete /data/misc/adb/adb_keys
And finally,
If you have access to another device (does not have to be rooted) and want to replicate its debugging permissions
Plug the 'donor' device into the computer first, then issue:
adb pull /data/misc/adb/adb_keys c:\temp\adb_keys
(Or replace "C:\temp\adb_keys" with whatever file path works for you)
Then, copy the file to the 'target' device in the same location (/data/misc/adb/adb_keys) and chmod 0644
I've tested all of these methods and they worked well.
In the end, I used the last method since my tablet had all the debugging permissions I wanted on my phone.
Thanks,I have the same issue with the same rom. I tried your solution and it worked.
Hi, I ran into this issue with my Moto G5 plus. The only difference is that I'm not missing the Revoke Auth option, even though using it does nothing for me, and I still fail to get the Authorization popup when connecting via USB/using ADB.
I tried the above method of copying the adbkey.pub file to my device directory, renaming, etc. I am doing something wrong and would like a hint.
I copied the adb_keys via Windows Explorer to my devices root directory. There was a /data/ directory, but only Titanium Backup had a subdirectory within, so I created .../misc/adb/, and placed the adb_keys file there.
I rebooted to the TWRP recovery Terminal, and navigated to the /data/misc/adb directory. I ran chmod, and the system could not find the file specified. Listing directory contents also showed the directory to be empty (yet when viewed in Explorer or LineageOS, it's visible).
Did I place the keys file in the wrong place?
Copying via windows explorer does not place it in the device root.

I was trying to Copy one donor device's Adb key file to my broken android phone to mirror it on my PC, Following the guide of another post, and somehow i stumbled across this post, after failing to copy from Donor device. Now i managed to copy the adb_key from Donor device but LOL my broken Android device is Unauthorized. What should i do? IS THERE ANY SOLUTION?

Do you have any way of writing to the /data/misc/adb/adb_keys file on the broken device?
I think i just did!

I rebooted into recovery mode, copied, but still the mirroring application is not working, still prompting for allowing USB debugging. Now i connected the donor device on That mirroring application and Saved the RSA of Mirroring application, and going once again. Wish me good luck

Well it didn't work since the Adb server of Cmd and mirroring application were different, so i searched for another application which has same server as Cmd, and luckily i found a great software by Genymobile, named scrcpy, from github, just one click on scrcpy-noconsole and boom? Thanks for all the help.

Cool, glad to help.
For a while, I looked for ways to get around this from a different angle (for example, making the keys match on the ADB server side) but I ran into some issues and ended up getting what I needed via the steps in the OP.
Glad you got it working though!
"And finally,"...you should have led with that
I cannot thank you enough! Other proposed solutions to this hellish problem made my head hurt. This was beautifully simple - copy file from the working device onto non-working, change permissions and BOOM! It works.
Thanks again, you're awesome!
Happy to help!
Oh my god, it's not a folder! Thank you so much! I was about to give up, this was driving me totally crazy. Everywhere on the internet they just keep repeating the same advice that did nothing, I actually created that as a folder and no wonder it wasn't working.
I still can't believe it's working now, ahhh...
can't believe in my eyes. work perfect for me. thanks you so much!!
I am trying to use the 'copy keys file from another device' method.
I've copied the adb_keys file to my PC.
Now, how do I copy that file from the PC to the data folder?
adb won't allow it as it's not authorised, what am I missing?
Thank you in advance for your help!

You can't copy to the device through ADB until you get ADB authorized... that's the whole point... you have to use some other method to get the file there.
I used TWRP custom recovery to copy the file from an external SD card the folder.
If you don't have an external SD card, use USB MTP/PTP, Mass Storage, a USB OTG adapter and thumb drive... if you desperate, zip the file and email it to yourself... pretty much endless methods of actually getting the file onto the phone somehow.
But you'll need root (or a custom recovery) to copy the file from wherever it is on the device to the correct location (/data/misc/adb/adb_keys)
You could potentially use several methods, for example you could use terminal emulator or a root file explorer to get the file to the correct folder.

Hey NFSP G35, thank you for the reply!
I figured there was something I was missing, I just don't know the steps to do it right.
I have a Moto X Play that has a broken screen, so no display, and does not accept touch input.
It powers on and is working as it was before the screen broke as far as I can tell, so I'm trying to connect it up to the PC to get all the data off it.
However, before it broke, something happened with the software that meant Google Play disappeared.
The device is stock Motorola device, so not rooted, no TWRP etc. USB debugging is enabled but not authorised.
What would you recommend is the best way to get the adb_keys onto the phone given the issues above?
Your help is greatly appreciated!
Sorry, given your circumstances, it's likely impossible or very difficult
?? Thanks, it worked perfectly on Samsung J6 run Evolution X 4.0
Thank you it's working
