[Q] adb push problem - Galaxy S 4 Q&A, Help & Troubleshooting

Hi
Brand new to the forum so not sure if this is the right place for this question.
I am trying to load the D2XX libftd2xx drivers from a windows 7 command prompt via this adb command:
adb push D2XX/libftd2xx-jni.so /data/data/com.ftdi.d2xx/libftd2xx-jni.so
I am launching adb fro within the tools folder, (shift right click etc)
The file libftd2xx-jni.so is within the D2XX folder which is within the tools folder (same as ADB).
I have tried various combinations of the above path name , even a full C:\ path with no success.
I keep getting this error message: Failed to copy 'D2XX/libftd2xx-jni.so' to '/data/data/com.ftdi.d2xx/libftd2xx-jni.so' : No such file or directory
Not sure what the problem is. Phone is NOT rooted so may be a permissions issue although I would expect to see a 'permission denied' sort of message?

How to push files through ADB

Prerequisites have...
A:android-sdk-windows installed
B: (on your phone) go to menu>settings>applications>developement and make sure usb debugging is checked.
C: the file you are pushing must be placed in the tools folder of adb so if you are pushing file "build.prop.txt" this needs to be downloaded/copy and pasted in C:\android-sdk-windows\tools
1: go to run and type cmd (or just open your command prompt)
2: cd C:\android-sdk-windows\tools
3: adb remount
4: adb devices *if everything is set up right this should output a serial number*
5: adb push FFFFFFF.FFF /#####/###### *i hope my notes help here you need to put the file name in for the F(s) and in the pound signs you put the destination on the devices example adb push build.prop.txt /system/bin
6. repeat step 3 for multiple files
7. adb reboot this is how you finish

i had the same issue with something i was trying to push. I think you need to make sure you have exactly the same file name like caps and all. i was trying to push rootexplorer.apk and i got the same message but i then changed it to RootExplorer.apk and it work.(notice the difference in caps)
just watch this and it'll explain everything.

Does it matter where sdk is installed my file path is
C:\Program Files\Android\android-sdk\tools
instead of
C:\android-sdk-windows\tools.
I just installed it in the default location.
I type adb remount and get the not recognised command.....
Thanks.
I don't think my phone is being picked up?

Make sure your have the drivers for your phone installed first of all.....Then, in your command prompt you have to change directories to the sdk (which you made harder by not installing to C:\
Try: cd Program Files\Android\android-sdk\tools
Then type: adb devices
That should return "xxxxxxdevice" connected....Then you know you have it set up.
Look in kyouko sig he has all the commands for adb

Flashing fresh ROM via ADB in Linux
Hello there.
M volumeUp and VolumeDown buttons are broken on my rooted Desire HD, so I cannot go through CWM any longer.
With regard to this post, I would ask the followings:
1) can this method be used to flash a new ROM (i.e. Coredroid, Leedroid..) without the need of those 2 buttons ?
2) My PC runs Linux. How does it work with this O.S. ?
Thanks

There is a thread somewhere on how to flash without a SD card and flashed using adb I believe, but don't take my word for it. Adb works fine with Linux, just have to set it up differently. Look in my sig and select the compile aosp on Ubuntu one and follow instructions on getting the USB set up.

Hi I need help. I accidentally wipped my phone in CWM and now I'm trying to use adb push to push the update.zip into my phone sd everything seems to work but then in CMW it says there are no files..
any suggestions?
[Edit]
nevermind
I kept trying different locations
not sure which one did the trick but I'll list the one's I tried
so \update.zip /sdcard/
.... /sdcard/update.zip
(note I put "/update.zip" thinking maybe it needed to be reallocated to the same file/destination
Can i use adb push *.apk /system/app to push several files at once, and then repeat but using *.odex instead of *.apk? I keep ending up getting the same error, and i want to find out which app is messing with me...

[Q] Error: adb is not recogzined as an internal or external command

Error: adb is not recogzined as an internal or external command, operable program or batch file???
i successfully installed the android sdk 08 and still got this message.
Has winxp, tmobile GT
I had this same exact problem, but I was just able to get it working. First, this website is helped a lot:
http://www.londatiga.net/it/how-to-use-android-adb-command-line-tool/
Also, make sure you download the Java SDK package from the link given on that website.
Second, when the website says to "Run Windows command line tool (cmd) and go to D:\android-sdk-windows\tool" open command prompt and enter this code:
cd (enter the path to where the android SDK was installed), for example:
cd C:\android\android-sdk-windows\platform-tools
Notice how I entered "platform-tools" instead of just "tools" because this is the folder where the adb file is download with the android SDK. After you do this, you should then be able to apply adb codes (make sure the screen on your tab is on because you will have to accept superuser prompts, therefore your tab needs to be rooted).
Every time you open command prompt, you will have to enter:
cd thentheplacewheretheandroidSDKisinstalled
as stated above before you are able to enter adb commands.
Hope this helps!
@caveman999 is giving good advice. Working in the command window is weird to those who did not use old pc-dos environment.
You have to be in the tools directory or you have to edit your PATH in windows so you can use adb from any prompt.
thnaks for both of you guys i installed the java jdk and also specified the path in environment variables but still error message!
I could only get adb to work error-free when I was in the same directory as adb.exe program. Just change directories cd..(enter) etc until you are in that directory.

I had the same error, until I downloaded and placed the .adb files accordingly.
Source: http://theunlockr.com/2009/10/06/how-to-set-up-adb-usb-drivers-for-android-devices/
"UPDATE: If it says adb not found or something similar, download the ADB files and extract them into the Tools folder of the SDK (they were taken out by Google in the R08 version for some reason and need to be put back)."
download adb files from here: http://www.megaupload.com/?d=RTEY0Q97
The important thing is to put the files really under the "tools" folder.
When you check out above Source I am sure your problem will be solved

[Q] ADB Can't Read Sideload

So, I've been trying to force over the 4.2 update to my N7 with adb. And every time I try to sideload the update, I get "adb cann't ready sideload"
I don't understand why it won't work. Every other adb command works fine. I'm on rev. 21 for sdk tools and 16 for platform tools. I literally just downloaded the SDK.
Any ideas?

I'm in the same boat! I tried, today, several times to sideload the update but I'm constantly getting the cannot read sideload error message. I guess I'm off to other sites to see what the fix is.
I had this problem too, but solved it this way:
Place the file you're trying to sideload is in the same adb directory, f.i. C:\Android
And when in the CMD window, change the active directory to this directory before you type: adb sideload [name of file]
So:
- run CMD window
- change your active directory to adb C:\Android
Code:
cd\
cd android
- type:
Code:
adb devices
(List of devices should indicate a number of the connected device)
- type:
Code:
adb sideload [name of file]
YES! i have found the solution. i just registered to share it to anyone with the same problem. i spend HOURS and HOURS, literally sweat and frustation like i've never experienced before to update this POS. i was ready to smash my one week old Nexus 7.
the solution is so simple and stupid that i want to smash my forehead on my keyboard.
i was using this video as a guide to manually update the N7 youtube /watch?v=iQhyerPfGes
what it doesn't say is that you DON'T HAVE TO UNZIP THE FIRMWARE!!!
You have to issue the command from the platform-tools folder (or the directory in which adb.exe resides). Right-click n the folder window and choose "open command prompt here." Then type
adb sideload 094f6629314a.signed-nakasi-JOP40C-from-JZO54K.094f6629.zip
Click to expand...
Click to collapse
remember, don't unzip the firmware
my Nexus 7 still doesn't finish the update because it say something about an error, but that's another problem
but at least i'm not getting "cannot read sideload" anymore :laugh:
I might be just an idiot but why are you guys trying to SideLoad a system update?
AFAIK... sideload is merely to install apps into your rom that Jellybean or the Playstore doesn't like.
I think you guys want to use "ADB Fastboot" commands instead. Get a guide before you attempt to do this though. I used Wugs Toolkit to install the bootloader from 4.2.2 update.

:laugh: true
For clarity:
- adb sideload can used for installing zip updates from PC, as an alternative for using the ROM/recovery manager on your tablet/phone.
Code:
adb sideload update.zip
- fastboot flash is used for installing img files to a specific partition (boot, recovery, system)
Code:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img

I was getting that message because my zip file already was a zip file and I named the file update.zip. Had to remove .zip from the file name then it worked.

This is what got me on the right trail. I opened the command prompt, navigated to the correct folder, used the sideload command and copied the name of the update file into the command prompt window, but it wasn't until I appended it with the .zip extension that it finally worked.:victory:
Hey guys! I don't have the sideload problem anymore, but, I get this error. cannot read '(name of file).zip'
I am either really dumb or this isn't working! I have it connected to adb device number and all working fine. I have the zip in platforms-tools cmd window opened etc. when i go to adb sideload and then top of cmd window edit paste the name of the file add .zip and it says can not read file!
Please help!!
Same problem...fixed
I had the same cannot read sideload problem.
The problem was when I renamed the update package (so i don't have to type in the ridiculously long file name), i renamed it as "kk.zip".
Because this was done in windows, the file system recognized it as "kk.zip.zip".
Just rename the file without ".zip" (just "kk")
then try again - in my example: adb sideload kk.zip
it works~

So I had a similar experience. when I tried to use
Code:
adb push
, it would say error:closed. This was weird since the device showed up when I ran
Code:
adb devices
.
When I tried to do
Code:
adb sideload xxx.zip
I would get the
Code:
cannot read sideload
error. I have Windows set to show file extensions, but decided to rename the file and remove the extension. Then I renamed it again and re-added the extension. After that, sideload worked like a charm. I have no idea what changed (if anything), but it worked for me!
Fix
For me all that worked was using an aosp for the sideload, and then copying the real rom once I had android booted.

Try addind ".zip" at the end of the file name in CMD. So if the name in the directory is ROM, type into cmd "adb sideload ROM.zip"

oddly this helped me a lot with another device. i was having the exact same problem and found this topic in searching for a solution. but after removing the extension, renaming, then renaming and re-adding the extension it worked. i also had to type adb sideload fielanme.zip.zip to get it working.

ADB Push/Pull simple guide

ADB Push/Pull Simple Guide​To Push a single file from PC to Android, in this case a ROM.zip, you must place the ROM.zip inside the same folder as your ADB and Fastboot files. Right click anywhere inside that folder while holding the shift key down to open the cmd prompt and run these commands:
adb devices
adb push ROM.zip /sdcard​
To Push multiple files at once using a single command do this:
In your SDK/Platform-tools folder, or whever you have your ADB files, create a folder called "tmp"
Place all the files you want to push into the tmp folder then run this command:
adb devices
adb push tmp /sdcard​
--Simple eh?
To Pull a file (In this case a TWRP backup located on the sdcard in a Subfolder of TWRP called BACKUPS) from device to PC or HARDDRIVE.:
Create a folder inside SDKplatform tools or where ever you have your ADB located. I call mine TWRP_Pulls. Inside that folder create a subfolder and give it the name of the backup/File you are pulling. In my case I name the folder by the backups date and numbers.
FOLDER Inside the ADB folder-->TWRP_Pulls
FOLDER Inside TWRP_Pulls-->2016-05-03--17-54-24​The full command would look like this:
adb pull /sdcard/TWRP/BACKUPS/ANDROIDSERIAL/2016-05-03--17-54-24_cm_surnia-userdebug_6.0.1_MHC19Q_bdf9ce04cf C:\Users\Name\Desktop\SDK\platform-tools\TWRP_Pulls\2016-05-03--17-54-24​
(Where ANDROIDSERIAL is your devices serial number and can be found by entering "adb devices")
Make sure you place a space between the first pull and the /sdcard and another one after the ROM.zip and before the <path to location>
adb pull[Space]/sdcard/TWRP/BACKUPS/ANDROIDSERIAL/
2016-05-03--17-54-24_cm_surnia-userdebug_6.0.1_MHC19Q_bdf9ce04cf[SPACE]C:\Users\Name\Desktop\SDK\platform-tools\TWRP_Pulls\2016-05-03--17-54-24​============================================================
CREATED BY: BillyMumphry for educational purposes only. I hope it will help some people as I know I sure fumbled with these Push Pull commands when I was learning.

Cannot Revoke USB Debugging Authorizations

So I've come across a quirk that I haven't been able to resolve and haven't noticed before getting my G5. When I run
Code:
adb devices
on my computer with my phone connected, it shows my device but says unauthorized. I cannot seem to authorize my device. I have tried:
Revoke USB Debugging Authorizations (option not available in Developer Options)
Delete adb_keys in /data/misc/adb/ (No adb_keys file in the folder)
Create adb_keys file on my computer using the computers public key (Phone deletes this file on boot)
I realize this is more of a general Android question, but as it hasn't happened to me on any other phone, I wanted to see if anyone else was having this trouble.
Same boat here, haven't been able to fix the issue. I believe there's a testboot3.img floating around that fixes it. I downloaded it awhile ago as I keep a eye on everything for this device. But I don't know if it does and if you flash a new boot.img I'd think it would override it. I've tried your method as well.
I am also having this issue. Does anyone have a solution?
To update this for those that need it; this toolkit worked to fix this issue for me in Linux. I just hit the red block in the upper left that says "unauthorized device" when the phone was plugged in. Not sure what the kit did but then my phone finally asked if I wanted to allow the computer access. After doing that I finally got "authorized" when running "adb devices" in ubuntu.
https://forum.xda-developers.com/g5-plus/development/toolkit-moto-g5-plus-toolkit-root-t3605203
A fix if you are running Windows (or Linux)
I just found a fix that worked for me.
(Although i got the "unauthorized" status with the phone running as usual, I didn't get the same problem when in recovery mode.)
I followed instructions from this site but needed to change Linux commands to simliar Windows commands: http://www.neuraldump.com/2017/05/how-to-fix-adb-unauthorized-error/
If you are using Windows, you'll need to follow the commands below:
- First things first:
- Phone: Check if you have a file called adb_keys located at: /data/misc/adb/adb_keys. If you have it, i would recommend you to backup the file. (I didn't have it.)
- Windows:You'll need to have a file called adbkey.pub located at C:\users\UserAccount\.android\
- Boot into recovery mode.
- Plug your phone into PC.
- Open cmd and run adb devices. It would show "recovery" instead "unauthorized".
- Create a new file called adb_keys file on your PC:
Code:
type NUL > adb_keys
- Now you need to copy the contents from the adbkey.pub to adb_keys, the new file you just created:
adbkey.pub is located at C:\users\UserAccount\.android\
(Needless to say you need to replace "UserAccount" when running the command)
Code:
type c:\users\UserAccount\.android\adbkey.pub > adb_keys
- Upload the adb_keys file to your phone:
Code:
adb push adb_keys /data/misc/adb/adb_keys
- Reboot and run adb devices. It should be working now.
(Thanks to Tony, the guy who posted this fix in his blog).
need help please. Cant do it. I have that problem on my moto g5 plus. Dont understand this. Windows 10 pro computer.
Edit: I solved using the adb_keys from my xperia and using root explorer on my moto g5 plus and paste on data/misc/adb/adb_keys
Awesome! You may need to change permissions like I did from using root user within a debian chroot. Just like ssh keys....
From twrp recovery console.
chmod 0644 /data/misc/adb/adb_keys
chown -u shell /data/misc/adb/adb_keys
That got me authorized and running a root shell to spoof fingerprint before getting past first Hello page of setup
Yep, it works on my side as well on a Samsung galaxy Note 3, RROS 8.6.1, very good tip!:good:
@mnoguti
thank you, this fix my Verizon Note 4 issue with Smali Patcher not detecting my phone.
Thank you! My Galaxy S4 GT-i9505 also had this issue and your guide let me succesfully use adb normally again!

type c:\users\UserAccount\.android\adbkey.pub > adb_keys
- Upload the adb_keys file to your phone:
Code:
adb push adb_keys /data/misc/adb/adb_keys
- Reboot and run adb devices. It should be working now.
(Thanks to Tony, the guy who posted this fix in his blog).
