I've got a droid razr; rooted, stock rom
I broke the screen accidentally and now the screen isn't showing anything and touch isn't working.
I'd like to recover all the data off my device, but since it's locked, it won't budge. Drives won't mount when I plug it into my PC.
I've got a previous backup which is a little older, but i'm interested in backing up the actual databases (texts, call logs, etc) and system data too, along with my images and personal data.
Is there any way I can perform a whole backup while the system is locked like this?
I've already searched the forum for previous threads with similar issues, but I couldn't find one with a viable solution.
Any help is appreciated, thanks in advance.
Partial Update
Hey all-
I've partially solved my problem.
I was able to get ADB working miraculously. I downloaded the Motorola Device Manager and installed it, also downloaded the Android SDK/Java SDK;
Using the sdk manager i installed the google usb drivers (im not sure it helped any way, but just in case)
after that I ran through the process of adb
Code:
adb kill-server
adb start-server
**plug in device**
adb wait-for-device
adb get-serialno
From there I was able to use "adb shell" and navigate around the file system; used su, went to /data/system/ and did "mv gesture.key gesture.key.bak"
I then restarted my phone and did a repeat of wait-for-device, and get-serialno just to verify the phone was connecting properly.
I then browsed to my computer and amazingly, the drives mounted, my sdcard, and sdcard-ext as removable drives and I was able to view the contents.
-------
So now, I'm stuck here with a device that's NOT locked, I can view my files, and I can navigate the file system.
My end goal is to be able to copy everything from /data/ to /etc/ /system/ /root/ /sdcard*/ /vendor/ /xbin/ and any other system file that's not available through the mounted drives.
I'll keep this thread updated, and if anybody has any help or clue on how I'd do this, it'd be greatly appreciated.
So far I've tried variations on "adb pull" using / as a root dir; trying to find a way to use the shell to invoke scp, ssh, or some other file transfer, but I get no network connection. While in the adb shell and doing any file operations, I get an error stating that it's a read-only file system as well.
Fixed
I just wanted to let you all know that I've resolved my problem.
Let me state the issue again.
- Screen and touch broke.
- Device locked with pattern
- Rooted
- ICS - Stock Verizon ROM
- USB Mode was UMC, not PTP/MTP
- USB Debugging enabled
I used ADB to delete /data/system/gesture.key and rebooted, effectively removing the device lock, and allowing drives & data on my SD cards to show up in explorer after a reboot of the phone.
After futzing around for a bit, I realized the phone was tied to my Google account, and I remotely installed "Droid VNC Server" (app name org.onaips.vnc)
From there I found a way to activate the VNC server through the ADB command line
Source: android.stackexchange.com/a/31957
Code:
Application located in
/data/data/org.onaips.vnc/files
With a root shell, run this
chmod 766 /data/data/org.onaips.vnc/files/androidvncserver
Then you can execute the vnc server from the command line
/data/data/org.onaips.vnc/files/androidvncserver
Run this to forward the port
adb.exe forward tcp:5901 tcp:5901
On your VNC client, connect to localhost:5901
From there I was able to get access to my home screen and pulled the notification drop down and changed from USB Mass Storage to Camera/Media Mode
Rebooted the phone, started the vnc server again, connected to it and moved some files around to my SD Card
In another adb shell as root, I was able to copy files from /data/data/ (or anywhere else I wanted) and write them to anywhere on /sdcard-ext/
From there in another command shell, I ran adb pull /sdcard-ext/datafolderfile
=========================================================================
I believe this to be the overall gist of things, though I ran into hiccups along the way, while I was messing around, I changed some permissions which caused my su executable to break and only be allowed to run shortly after booting the phone; and also because of the broken screen, something would cause the phone to reboot every so often, breaking my connections, backups, file transfers, and etc
There's also a cool option in adb
Run
"adb backup" and it'll give you all the switches, you'll have to confirm the backup on your phone, so be sure to be running VNC and confirm it, but adb backup should be able to grab everything you need. Like I said it didn't work for me because my phone would reboot;
I hope everybody that sees this can benefit from it

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???

I have been recently messing with a Verizon ellipsis 7, it is rooted and I was trying to install some android 5.0 apps, boot animation, and fonts. Well I got a bootloop so I adb'd in and undid my modifications by pushing my backup of /system. Well that is where I went wrong Im guessing, I know have no access to adb shell, everytime I give that command I get this error
Code:
C:\android-sdk\platform-tools>adb shell
soinfo_link_image(linker.cpp:1635): could not load library "libc.so" needed by "
/system/bin/sh"; caused by load_library(linker.cpp:757): too small to be an ELF
executable: libc.soCANNOT LINK EXECUTABLE
Next I did adb pull /system/lib/libc.so and it is 0k in size. Now here comes the interesting part I did not modify my tablet yet to allow me to run adb in root mode so I cannot push the correct libc.so file to regain access to the adb shell. I am now stuck on the android screen (it is just stuck there not looping) can not run adb logcat because I have no access to shell and cannot push anything to the /system folder because I cannot run adb as root. So what do yall think, am I screwed?
Anyone have any idea?
im in the same mess, i messed with my system directory, got stuck on the verizon screen adb'd a backup but no go. wish i could help.
any idea of how to get root inside factory mode? my backup wasnt rooted
Hello everyone,
I have a Samsung Galaxy S II (I9100) with Cyanogenmod 11 (Snapshot M12) installed. Recently I dropped my phone and the screen was completely shattered. The display does not work, neither does the touch. However, the phone works fine as I can turn it on and connect it via USB to my computer and access the data on my internal memory. Although USB debugging is enabled on my phone, I am unable to do anything because the computer isn't authorised i.e. I cannot press "OK" on the authentication prompt that I would have otherwise normally seen on the screen (screenshot attached). Is there any way to bypass this prompt or a workaround for it? I basically need to get a Nandroid backup of my phone and then factory reset it.
P.S.: I tried to access my phone via a program called "Android Control" but apparently it is practically useless without the debugging privileges.
Thanks.
Solved!
This guide assumes that USB debugging was enabled on your device before you broke it. You can enable USB debugging via recovery using:
Code:
adb shell
echo "persist.service.adb.enable=1" >>/system/build.prop
echo "persist.service.debuggable=1" >>/system/build.prop
echo "persist.sys.usb.config=mass_storage,adb" >>/system/build.prop"
reboot
After digging through various threads I finally managed to bypass the secure USB prompt on my Galaxy SII with a shattered screen.
For this method to work you need another device running Android 4.4.2 or above with USB debugging enabled and the same computer authorised from that device i.e. connect that device to your computer and press "OK" on the authorisation prompt that appears on screen for secure USB debugging. Let us call this device the "authorised device".
"adb_keys" is the file we need from the authorised device which is located in /data/misc/adb/
Normally you must be rooted to take the adb_keys file from the device using "Root explorer" or "ES File Explorer" but I will assume that the authorised device is unrooted. You don't need to root it. However, if your authorised device is rooted then simply copy the adb_keys file on your computer and jump directly to Step 5.
Steps:
Connect the authorised device to your computer using USB (debugging enabled) and open a command prompt with administrator privileges.
To get the "adb_keys" file, use this command:
adb pull /data/misc/adb/adb_keys <destination path>/adb_keys
For example:
adb pull /data/misc/adb/adb_keys c:/adb_keys
The above command will save the adb_keys file to the root of your C: drive. You can change the destination folder to your liking. Now the job of the authorised device is done. You can disconnect it and disable USB debugging.
Once you get a copy of adb_keys, reboot the phone with the broken screen into recovery.
Now connect the broken phone to the computer using USB.
We need to copy the adb_keys file to the broken device. Use the command below:
adb push <file location> /data/misc/adb
For example:
adb push c:/adb_keys /data/misc/adb
After the file is copied, reboot your device using "adb reboot" and voila! You can now use adb shell.
Special thanks to torankusu for this post which helped me compile this guide.
Check out this thread by k.janku1 if you want to have full control over your device even with a broken screen (requires Java Runtime Environment and Visual C++ redistributable). This tool lets you use your device through your Windows PC even if your touchscreen doesn't work or you can't see anything.
P.S.: My broken device was a Samsung Galaxy SII running Cyanogenmod 11 (M12) and my authorised device was an unrooted Moto G running stock ROM.
Thanks man.
I'm (noob) trying to follow the guide which exactly fits my situation.
Status : Broken SGS7 screen with USB debugging enabled but cannot accept the computer
SGS4 backup phone where i extracted the adb_key
both are not rooted and running stock OS
Unfortunately i get stuck between step 6/7... When i reboot to recovery mode the windows does not recognize neither of the phones when conneted to USB. Therefore i cannot run the ADB command and copy the key on my broken phone (SGS7).
i can choose the "aply update From ADB" and then the computer recognizes the phone and i can find it in ADB devices "sideload" but here i cannot use the command "adb push....."
Ii've tried updating drivers googled alot, but without luck...
what am i missing?
input very appreciated
I too am a noob who was trying to follow this guide, which also exactly fit my situation. My status was a broken Sony Xperia screen with USB debugging enabled, but I was unable to click on the "accept" button whenever I hooked my phone up to my PC. I extracted a working adb_key from my new Asus ZooXS phone; neither phone is rooted, and both are running stock Android OS.
Unfortunately, I got stuck right between Steps 7 & 8; Windows did not allow me to use the ADB Push command to copy the key onto my broken Sony Xperia. I could Pull the key from my Asus using ADB just fine, but not the other way around.
I did eventually find an alternative solution: I used an OTG device & hooked up a mouse to my Sony Xperia so that I could get past the broken screen issues & navigate to Settings > Bluetooth. I then borrowed a Bluetooth Mouse & "discovered" it with my broken Sony Xperia. I could then unplug the OTG device & re-connect my phone to my PC via USB, & then click on the screen using the Bluetooth Mouse to "accept" my computer as always being authorized to perform USB debugging. Afterwards, I was able to use Helium backup to pull off most of my important data from my phone.
Hope this helps others who are running into the same problem....
i don't get it - authorizing adb via adb
The steps maq_ posted helped me rescue my data from my broken OP3. Combined with the information from here: https://stackoverflow.com/questions...b-rsa-key-with-broken-touch-screen-on-android which indicates the files between the computer (running adb) and the key file you copy to /data/misc/adb should "match" with each other. Indeed, you might need to have been bootloader unlocked (with a custom recovery) to use adb push to copy the adb_keys file to your broken phone. For me, since my broken phone was rooted I used a terminal emulator with the 'su' command (after successfully getting the file onto my broken phone) to copy the file over to /data/misc/adb.
Some tips that might help newbs before following maq_'s steps: First, re-install another copy of adb (remember the path you installed to on your PC). Second, erase contents of c:\Users\$name\.android\ (which contains existing keys generated by adb). Third, run adb kill-server to make sure other instances of adb don't confuse things.

Thanks for clarifying TWRP and UNLOCKED bootloader is required.
TWRP is not available for some devices. Luckily i found a ported recovery.img for my broken tablet. Unfortunately adb shows device as offline in TWRP, adb does not work in recovery.
I finally managed installing adbkey.pub via script. does not work on dm-verity, KNOX enabled or locked devices!
1. install ODIN (Samsung) or SPFLASH tool (MTK)
2. get the firmware for your device (fw.updato.com)
3. unpack system.img
4. add your own shell script (backdoor) to /system/etc/init.d, /system/etc/install-recovery.sh or whatever
5. repack your custom system.img
6. flash system.img
7. copy RSA Key to /sdcard via MTP
My (backdoor) shell script was a watchdog looking for another shell script on /sdcard. The second shell script was copying adbkey.pub from /sdcard to /data partition. This worked without root because init scripts run with root permissions on boot.
With this method i was able to backup userdata from my broken tablet via adb. TWRP has adb backup option too, in case touch screen is broken.
I will explain in detail on request.
edit: for experts only: instead of flashing whole system.img, you can do slight modification using Tarek Galal inception Utility via ODIN, for example "Place your adb keys, configure USB debugging"

ThanK You Senior for posting the solution.
Can you please help me in this.
I am using mediatek device
Didn't find /system/etc/init.d
Didn't find /system/etc/install-recovery.sh
But found "" install-recovery.sh "" inside /system/bin folder
Now do i have to only paste the your given rsa_copy.sh scrip in this file?
and paste the pub_keys from authorize device to /sdcard/
That method will most likely fail because dm-verity deny booting if any modifications detected. You can however patch boot.img with Magisk (to disable dm-verity). What android version/mediatek device you have?
Yes you can replace install-recovery.sh or add line
Code:
/system/bin/sh /path/to/rsa_copy
/system/bin/sh /path/to/99userinit_daemon
But I do not recommend this method any longer, modifications in /system should be avoided. Instead you could simply disable RSA authorization and enable usb-debugging in default.prop

I recommend AIK it is capable of re-signing AVBv1-signed boot.img
I have android 7

I attempted this trick with working phone's boot.img (working img) but even after repacking boot.img without edits phone stuck/hangs on boot (without animation)
Recommend me a good tool for unpacking and repacking boot.img with guide.
(I already tried with android kitchen on Linux (This one's boot.img make phone report after boot animation) and unpack/repack Tool on windows ( http://www.mediafire.com/file/nvo2popw26k4mit/IMG_Extractor_2.0.rar/file) and this one's boot.img doesn't boot phone to boot animation and hangs on initial logo)
I tried this on other working phone
@osm0sis may have a look into boot.img can you upload please?

Yes please,
LT700 is for testing purpose workig phone.
Both phones are almost from the same manufacturer (Note: but different models) Even unmodified repacked file does make phone boot success.
Uploading both stock and magisk patched working images of both phone
Here is how I succeeded to enable USB debugging (also adb and remote view) on Samsung Galaxy Note 4 with broken screen.
1. Following the DeathDrifterz's advice I was able to set the device in recovery mode with ROOT access and adb :
DeathDrifterz said:
So, I have a Galaxy Note 4, broken screen, broken digitizer. Do not have access too an MHL cable or Mouse to hook up to TV. The phone has a password and usb debugging disabled, so kies and the computer won't recognize it. Not even when in download mode. I did flash CWM rcovery to the phone, but this still wouldn't allow me to see the phone in recovery mode. What did work was I downloaded the trial version of Wundershare Dr. Fone, booted phone into download mode, let the program run and start searching for files. Stopped the program. Unplugged the phone. Exited Dr Fone. Opened cmd in the platform-tools folder of the SDK platform. At this point, I was now able to see the phone, in recovery, listed under ADB Devices.
So Dr Fone took the phone from download mode (vol down + home + power, then press vol up after vibrate) to recovery mode once it started finding files. Disconnect the phone from the PC, exit Dr Fone and reconnect the phone to the PC. It will still be in recovery mode. Open cmd prompt in the platform-tools folder. adb devices shows phone in recovery, used adb pull /sdcard/ and it worked like a charm. All files on the phone have now been downloaded.
Broken screen, no digitizer, password locked, USB debugging disabled, and it was free. Took 5 minutes once Dr Fone was downloaded (will take longer if you don't have the sdk tools.)
Hope it helps.

2. In other forum I found tutorial how to enable USB debugging from recovery with root access :
Connect the device to Mac or PC in recovery mode. (I had to map the process in my mind as the screen was broken).
Now open terminal/CMD in computer and go to platform-tools/. type and enter ./adb devices to check if the device is connected in recovery mode.
To mount the respective directories, type:
Code:
./adb shell mount data
./adb shell mount system
Get the persist.sys.usb.config file in your system using:
Code:
./adb pull /data/property/persist.sys.usb.config /Your directory
Now open that file in a texteditor and edit it to mtp,adb and save.
Now push the file back in the device:
Code:
./adb push /your-directory/persist.sys.usb.config /data/property
Get the build.prop file:
Code:
./adb pull /system/build.prop /your-directory
Add these lines:
Code:
persist.service.adb.enable=1
persist.service.debuggable=1
persist.sys.usb.config=mtp,adb
Push build.prop back into the device:
Code:
./adb push /your-dir/build.prop /system/
This way you enabled USB debugging on your device. But you still can't connect. Why? Because it asks for RSA verification. If you could view your display then you could easily tap on YES to authorize the device.
3. Skipping RSA verification :
The ADB keys (after authorization) are saved in /data/misc/adb/adb_keys, so I have one Samsung Galaxy S3 with working display which already authorized my PC.
So I got the adb_keys file from it. I connected the Samsung Galaxy S3 to my PC and use :
Code:
./adb pull /data/misc/adb/adb_keys
Then reconnected the Note 4 and pushed the file in it:
Code:
./adb push /your-dir/adb_keys /data/misc/adb/adb_keys
4. Reboot! And Voila: the devices boots normally and adb connects without asking for verification.
After that I used Vysor chrome extension and Vysor apk to view the device screen and act with the device.
I installed the apk with :
Code:
./adb install apk_name.apk

It works! With the first method.
I have Samsung Galaxy s5, lineage os 14.1,
After my screen broke, I couldn't see my device through adb devices, no matter what driver I have installed - and believe me I've tried all the methods.
Then I've installed CWM recovery, adb recognized it in devices but I wasn't able to pull sdcard with adb pull command in Windows 7. I got access denied.
Then I saw this post and I got access to sdcard!
Works on OnePlus One with Lineage 14.1
Works like a charm on my OnePlus One with lineage 14.1
Just want to mention that if you have problems mounting /data and/or /system
I got help from this post: https://forum.xda-developers.com/galaxy-s2/help/mount-adb-t1107545
Basically, the dirty solution I found with help from kaukassus post was:
1.
Code:
adb mount
- to view name of available mounts and identify /system and /data
2.
Code:
adb shell mount -o rw,remount -t yaffs2 /dev/block/[U]mmcblk0p28[/U]
underlined is the part that is different
- to mount the data folder. Do the same for system. Then I just followed the steps from this tutorial.
The part with the RSA verification I resolved with a little help from https://gist.github.com/varhub/7b9555cdd1e5ad785ffde2300fcfd0bd
Enable ADB (2/2): RSA verification
For the RSA verification that you asked to bypass, I don't know whether it would work in your device, but it worked in my little experiment. In Lollipop, the ADB keys (after authorization) are saved in /data/misc/adb/adb_keys. Your private key is saved in computer. In Linux the directory location is $HOME/.android/. On Windows that usually translates to %USERPROFILE%.android, but keys might end up in C:\Windows\System32\config\systemprofile.android in some cases.
adb push ~/.android/adbkey.pub /data/misc/adb/adb_keys

Thanks for post
Worked top to bottom, on my Galaxy S5 6.0.1 (ALEXNDR ROM)!
Used step .2, .3 and oledolez tips aswell.
Got the screen cracked and black, went crazy because I had the SD card encrypted and couldn't get the stuff outta there...
Thanks a lot!

GS5 CWM Stock ROM
Hello ! I broke my gs5(sm-g900f)'s screen and now it is constantly black. I tried everything on the thread and my device is always shown as unauthorized in vysor or when checking in ADB with /adb devices. This means I have succeeded to enable USB Debugging through ADB, however I must be having problems with the RSA key. Any help would be appreciated!!
Thanks in advance !
Dan
P.S The phone was completely stock when I broke it and I blindly installed cwm-6.0.4.7 and CF-auto-root with odin, so maybe there is a problem with that ?
what if the partition is encrypted? How I would enter the boot password with a broken screen?

I had the same problem and fixed it in TWRP doing this command:
Note: Use this command only if your /data/ partition has the ext4 file system. There are some other similar commands for other file systems, but i don't remember they.
Code:
adb shell make_ext4fs /dev/block/[B]mmcblk0p20[/B]
(Bold part can change depending of your device)
Then just do a normal wipe and flash again the ROM.

Dear experts,
I've been trying to follow the above steps but cannot get data and system mounted:
PS C:\Users\Azubi\AppData\Local\Android\Sdk\platform-tools> adb devices
List of devices attached
52001077b43913d3 recovery
PS C:\Users\Azubi\AppData\Local\Android\Sdk\platform-tools> adb shell mount data
mount: mounting /dev/block/mmcblk0p21 on /data failed: Device or resource busy"
I'm trying to access a Galaxy S5 mini with broken screen and digitizer. It's rooted and runs with TWRP and Lineage OS.
The aim is to enable usb debugging in order to mirror the screen on pc.
Has anyone been encountering this already and could help?
Many thanks
Max
