[Q] Android side adb push - EVO Shift 4G Q&A, Help & Troubleshooting

I wanted to know if there is some way to run an equivalent android-side version of the adb push command, with "file1" being located somewhere on the sdcard instead of on the computer
Code:
adb push file1 /data/local/tmp/file1
Becomes
Code:
/sdcard/file1 /data/local/tmp/file1
The phone running this command would be unrooted. I have tried using "mv", but it gives me the message "error: cross-device link".
Any help would be appreciated
This is for an unnamed project that I am working on, though some of you might be able to figure out what it is....

The commands are the same. Just like Linux users can follow Windows directions but with some substitutions.
Download the SDK here: http://developer.android.com/sdk/1.5_r3/index.html
Follow the instructions here: http://developer.android.com/sdk/1.5_r3/installing.html
Once you have the SDK setup, you can follow the steps given in the rooting threads/wiki. Any time it says to enter a command you do it in your terminal (which on OSX i think is Terminal.app, use Spotlight to find it).
Hope this helps a bit.
i dont get this:
Code:
On a Mac, look in your home directory for .bash_profile and proceed as for Linux. You can create the .bash_profile if you haven't already set one up on your machine
i don't have that .bash_profile how do i create it?
thanks
Google easy to use and always there for you.

yeah but all tutorials are made for xp or even linux.
I have tried to create it using vi command then edited with the path o the sdk tools
but when i type adb it doesn't do anything
i am stuck there
Did you check my link for your bash_profile ? This help at all?

Try reading this:
http://www.tech-recipes.com/rx/2621/os_x_change_path_environment_variable/
Sounds like the Path variable may be in a different file. It is the same on linux, I think it can be in a few places.
Irf you want to use adb without messing with your path you can do the following:
Code:
cd <android-sdk-location>/tools
./adb devices
This is convoluted so get that PATH working and everything should be nice and easy! Good luck.
I use a Mac, and when I was getting started I used the linux tutorials with no problem.
i can push the 2 files using commands to my sd. Adb devices shows my htc ok
but after i enter to fastboot mode the device is no longe shown
i type
Code:
./fastboot boot recovery-new.img
but the only thing i get is
Code:
-bash: fastboot: command not found
i am on tools directory on terminal
i think fastboot is not in the tools directory ...
i'd rather say the error is caused by that then a missing connection.
Does the phone write "FASTBOOT USB" ?
if you type "ls", can you find a file named fastboot in your directory?

The files have to be executable. You can do that by running:
Code:
chmod -R +x /path/to/tools
This makes all the files in the tools directory executable with ./
About the .bashrc or .bash_profile if you don't have one in your home directory you can safely make one. With the following command:
Code:
echo "export PATH=$PATH:/path/to/tools/" > ~/.bashrc
or if the file exists just do:
Code:
echo "export PATH=$PATH:/path/to/tools/" >> ~/.bashrc
Remember to restart the shell after you are done with this.
the reason adb work for you is because adb is in tools directory
fastboot does not. You have to get fastboot somewhere else
Whenever you get command not found, you can run another command to check
ls <program you ran>, and see what happened
Example
in your tools directory, where you have no problem running adb push, try doing "ls adb", without the quote
in your tools directory, where you have problem running fastboot, try doing "ls fastboot", without the quote
and you should see what's going on
BTW, this is fairly basic unix environment. If you are having trouble at this stage, you need to get yourself more familiar with unix environment, which is what osx is based on
I am sorry, but i don't really know where's good tutorial on unix
On google, i just search for "mac osx unix shell tutorial:, and come across this site
http://www.osxfaq.com/tutorials/LearningCenter/
Hope this help
Edit 1: btw, here's where you can find fastboot for MAC. Put it in your tools directory. IF you keep the filename as is, you need to type fastboot-mac whenever you see someone mention fastboot
http://www.htc.com/www/support/android/adp.html
yeah you're right fastboot is not on that tools directory. in fact i have looked into the whole sdk folder and i can't find it.
thanks
hey i managed to apply the update thanks to having fastboot-mac on tools folder
but after booting i go to terminal to apply the final step and i get this
Code:
MBdeluxe:tools cesarleon$ ./adb shell flash_image recovery /sdcard/recovery-new.img
error reading /sdcard/recovery-new.img header: Is a directory
what's wrong ?

Are u sure that recovery.img got transferred properly? Maybe check the rights on it (it not read only or something). What if you mount the sdcard in OS X and copy and paste (vs push)?
If you're trying to flash the recovery image, try
Code:
adb shell mount -a
adb push recovery-new.img /system/recovery.img
adb push recovery-new.img /sdcard/recovery-new.img
adb flash_image recovery /sdcard/recovery-new.img
Hope that helps
adb shell mount -a

Very odd error message
Do this to check what your phone's sdcard looks like
Code:
adb shell ls -l /sdcard/recovery-new.img
Next, you should grab the file from your phone to your computer. This step assume you are in your tools directory
Code:
adb pull /sdcard/recovery-new.img recovery-new-phone.img
Finally, try to compare the file you have on your computer against the one you got from your phone, and see if they are the same. This assume you have your working recovery-new.img in tools directory
Code:
diff recovery-new.img recovery-new-phone.img
I have not try this diff command, and I assume it'l handle binary diff
If diff can not handle binary file, do ls and check file size. both file should match
Code:
ls -l recovery-new.img recovery-new-phone.img
If your computer and phone recovery-new.img are not the same, download to phone again

You will get Failed Mounts when u run
Code:
adb shell mount -a
You CAN ignore them.
See here: http://forum.xda-developers.com/showthread.php?p=4029461
This may not be the right way to do it but I always just downloaded the recovery to the tools directory of the android sdk. Then fire up the phone in fastboot mode and do:
./fastboot flash recovery recovery-new.img
(replacing recovery-new.img with the name of the downloaded img file.)
I'm sure there is a reason people are doing it the other way, but for myself one command to do the flash is alot easier!

[WINDOWS][TUT]ADB tutorial, setting up ADB, usefull commands, collecting debug info.

Hi all.
Everyone here on our forum wants to help devs by testing different stuff but devs wants testers to send debug info to them so they can resolve bugs. Notifying bugs without logcats is useless and some users don't know how to collect these debug data.
To collect debug info there is a tool named ADB (Android Debugging Bridge). we r very small community and there are not plenty of sgr users around here so we have to worry about knowledgeable testers. so i m making this basic instructional guide to ADB. about how to set up ADB on windows and some basic usage.
Setting up ADB on windows.​
Know this first.
> ADB requires usb drivers. So first of all install kies so that ur pc detects ur phone and ADB can recognise ur phone.
> Android is linux based and in linux commands are case sensitive so while typing these command use propare case otherwise commands won't execute.
> Windows uses back slash [\] and linux uses forward slash [/] so while typing file locations. For location of file in ur pc use back slash and for files in ur phone/sd card use forward slash.
there are two ways to setup adb on ur windows pc.
1 > download the android sdk, it includes the adb
u can download latest android sdk from HERE.
2 > only download adb package, no need of downloading the whole sdk.
look at the end of post to find the zip file of adb package.
now after downloading:
if u have downloaded sdk read this:
> after downloading sdk, extract it to ur desired location.
> after extracting, open that folder and goto "platform-tools" folder.
> now hold the shift key and hit right click in that directory
> click "open command window here"
> u will see command promp, type "adb" in command prompt. if adb executes means u have successfully setup adb on ur windows.
if u r using without sdk:
> just extract the package
> hold shift key, hit right click and choose "open command prompt here"
> type "abd" in command prompt and check if adb executes.
now as we have successfully setup adb lets begin to some basic commands.
first of all connect ur phone using usb cable. make sure u have checked usb debugging in settings>applications>development>check usb debugging.
now open adb as mentioned above and type
Code:
adb devices
u should see
Code:
list of attached devices
xyz device
xyz will be name of ur device, as default it will be some number.
Basic usefull ADB commands​
1.
Code:
adb pull
this command can be used copy files from ur device to ur pc.
for eg.
Code:
adb pull /system/app/Camera.apk
this will copy the camera app to the directory where adb is extracted.
if u know the path u can copy anything using this command.
2.
Code:
adb push
this command can be used to push files to ur phone.
type the command, drag and drop the file in command prompt and than type location where u want to push that file and hit enter.
for eg, if i want to push image named android.jpg stored in my C drive.
Code:
adb push C:\android.jpg /sdcard/
this will push that image to sdcard.
sometimes we have to push some packages in specified folders. just type the location after file name.
for eg
Code:
abd push C:\sanim.zip /system/media
3.
Code:
adb install
with help of this command we can install apps to our phone dorectly from pc.
for eg. type "adb install" than leave one space with mouse choose apk file of app u want to install and drag and drop it in command prompt. path of that app will be displayed in command prompt. like this.
Code:
adb install C:\adb\Camera.apk
by executing this command u can install the app u have dragged and dropped in command prompt.
As i have written for windows but these commands can be used on ADB on linux/MacOS as well but i have only mentioned the set-up guide for windows only.

Getting Debug Infos (Logcats)​
1. logcat
logcat is a report from android logging system which runs in background from the moment u boot ur phone. and it haves all the info what went wrong with system.
generally we can see logcat by typing
Code:
adb logcat
but that will show the constant data flow so better save it as file so can be sent to dev or u can study it later.
Code:
adb logcat > log.txt
this will store the logcat to directory of adb and collect log in text file.
2. bugreport
Code:
adb bugreport
bug report prints dumpsys, dumpstate, and logcat data to the screen. which can be used for bug reporting.
3. Java Debug Wire Protocol
Code:
adb jdwp
this command prints the list of available JDWP processes on connected device in command prompt.
Logcats On Mobile​u can directly generate logcat on ur mobile using Terminal Emulator app, there are many terminal apps in market. CM comes with pre-loaded Terminal Emulator.
some terminal apps:
Android Terminal
Terminal Emulator
RomToolbox
u will need root access to generate logs
open terminal app, u will see following screen
Code:
$ export PATH=/data/local/bin:$PATH
$
now type su and hit enter.
allow super user permissions.
now to get a logcat type following command.
Code:
logcat > /mnt/sdcard/logcat.txt
this will generate text file named logcat.txt on root of ur sdcard which is containing logcat.
to get DMESG (Kernel Debug)
open terminal and type following command
Code:
su
dmesg > /mnt/sdcard/dmesg.txt
this will generate text file named dmesg.txt on root of ur sdcard which is containing kernel debug log.
Kernel Debugging.​
we can use adb to debug kernel issues.
Code:
adb shell
dmesg
this will generate a log which is very helpful to resolve kernel issues, we just have to send this log to dev, he will look after it.
sometimes after flashing kernel we go into bootloop in that cases generate logcat using this commands and send to dev it will be very helpfull for dev to know and resolve reason causing bootloop.
Code:
adb shell
cat /proc/last_kmsg > /sdcard/last_kmsg
this command should be executed immediately on reboot otherwise it will be over written by new kernel message. the file will be stored on root of ur sdcard named last_kmsg. send this file to kernel dev it will help him great to resolve the problem.
Read this if u dont know how to get files from ur sdcard even if ur phone is not booting and stuck at bootloop.
u must have CWM to do this.
>boot ur phone in recovery mode (by holding VOL UP and HOME key together on boot)
>goto "Mounts and Storage"
>Select "Mount USB Storage" and plug in your data cable.
>Now u can access ur sdcard on ur pc, after ur work is done click "Unmount"

Hello I am trying to create a batch file that has an infinite loop and was wondering if there are any adb commands that can do this.
I am also looking for an adb command that waits x amount of seconds before performing the next command.?
Any help would be greatly appreciated

ADB

Hello, I have a problem. I'm trying to do some things from my pc in the phone with the ADB Shell and not let me.
My problem is that I put adb: not found.
I do this:
i1141.photobucket.com/albums/n582/RyuuDrakonShis/7.png
Worth up here all right but when I have root permissions and everything working I put the commands and none let me get adb remount such or adb pull and nothing makes me adb: not found.
Thank you.
I'm not sure if that's a screenshot from your own computer or not.
On my computer adb resides in C:\adb. So when using it I type:
cd C:\adb
Then, to make sure it sees my device, I type.
adb devices
If it returns a device, great. Otherwise check your usb cable and driver.
I have a feeling you need to tell cmd prompt where to look for adb by using the cd (change directory) command.
For instance, if your adb install is located in C:\Users\User1\adb, you would type cd C:\Users\User1\adb, and hit enter.
adb stands or Android Debug Bridge. It's a command line tool that comes with the Android SDK (Software Development Kit). If you develop for Android, you should know where it is.
Anyway, in my case it's in C:\Program Files (x86)\Android SDK\platform-tools\adb.exe
Google Android SDK to get it.
If you have adb, and you're typing: adb shell, then you go to the Android shell. You don't need to type "adb" inside the shell again!
What I mean is:
Code:
adb shell ls
it's the same than:
Code:
adb shell
ls

[GUIDE]( Easiest) All about ADB, logcat, shell

ADB:-
Android Debug Bridge
Very useful program made itself by Google for Programmers and developers. Its based on command line and basically communicates with your Android to respond to certain commands. There is vast amount of knowledge about adb but its most useful commands limit to getting:-
Logcat:-
A real time log of what is happening in background of our devices. It is really useful for developers to see which component has malfunctioned and helps to narrow down their search for what failed and what needs to be fixed. Several times users are asked to give logcats of their devices which are giving errors. We will go in detail that how to get logcats in every and easiest way possible.
App Installation and Management:-
adb proves really handy if you want to install apks directly from your PC or want to batch install or delete them.
Shell Execution:-
You must have heard of Terminal Emulator. It is an app for android to execute shell commands(linux commands) which are basically present as applets in /system/bin, /system/sbin or /system/xbin(in our case) folders. A very imporant applet called busybox is installed there mainly used for execution of basic commands during root browsing or ROM installation. Many times updater script of ROMs use busybox commands to install it. Well, these commands can be initiated from your device too but they can be initiated from adb also making it easy for programmers.
Pushing and Pulling:-
Most used commands of adb. adb makes it a piece of cake for new device developers to get an ideo of structure and basic knowledge of devices by pulling command. We can pull out i.e copy any files or folders from our devices to our PC, even the root directories without rooting the devices. It help rooters and ROM chefs of new devices to get an idea and implement their mods on them. Pushing is also very useful command. It copies your files and folders from PC to your device. Very useful in pushing some /system apps and other things
Remounting and setting permissions
Basic commands:-
Of-course basic commands such as reooting and rebooting in recovery ode and download mode are supported.
Others:-
There are several other features of adb such as fastboot, aapt, etc
Setting up ADB
Pre Requirements:-
A little amount of brain
PC(This is a windows guide, if asked I will add linux and mac guide later)
Java Runtime environment or Java Developing kit
Your Device Drivers
An Android Device
Assuming you all these ready and working properly, we continue
If you are having trouble completing Pre-Requisites, there are several guides featuring them too
Start
1. First Download Android SDK. Roughly about 70 MB
2. There may be any compressed zip file or exe file
If zip file, then extract it to C:\android-sdk
If exe file then double click on it and install it in C:\ Drive(or any other drive you want)
3. Now to get adb and other tools, you need to download 'Platform Tools'
To download them, go to the android-sdk folder and double click on SDK Manager
It will ask you which package to download? However, it is your choice which package to Download, but here, we will only talk about platform
Tools. So, simply tick on Platform Tools and click on install. Once you have done it. Go to the platform-tools folder in the directory where you installed android-sdk. You will find several files there like adb, fastboot, aapt, etc
4. Now, you can backup the whole folder of android-sdk to any external storage that will make you not download package
again if you want to. You can have it placed in any computer and run it as it does not require registry to work
5. Now, you are just one step away from using adb. Next step is SKIPPING SETTING ENVIRONMENT VARIABLE
Many guides on internet say that it is to be done for making it easy for users and if you have some basic knowledge of Command Prompt,
you will know that to execute any application with command prompt, you first need to change the directory to the one where application is
placed. And to skip changing the directories every time you open CMD, you need to put that application is environment variable. Howeve, we will not do so.
6. Type cmd in the search bar. Copy cmd.exe from there. Go to the directory where you have installed android-sdk. Go to platform-tools folder. Paste cmd there, right click on it and in the settings, select Run as Administrator.
7. You are done. Now what to do in it?
ADB Commands
Type adb in command prompt. And several commands will show up on your screen. It is very difficult to analyse these all commands, so we will only talk about most used and important commands
Connect your device via USB cable
And open the CMD in platform-tools folder(Make a shortcut of it on desktop). And type the suitable commands
Code:
adb devices
Will show the list of devices attached to the PC andtheir serial numbers. If this shows up correctly on your PC, then it means that everything is fine for continuing.
Logcat
Code:
adb logcat
It will display the real time log of your device
Best time to do it is when your device boots up
Now, many users ask me how to copy the logcat and upload it from CMD
There are several methods:-
1. Right click on the Title Bar of Command Prompt. Hover the cursor over edit and select mark. Select all the things you want to copy and then click enter. All the things will be copied to clipboard.
2. This is the correct way of getting logcat saved.
Code:
adb logcat > logcat.txt
This command will create a logcat.txt document in platform-tools folder with the complete logcat of the device. Ofcourse you can type any name instead of logcat.txt
3. I prefer taking logcat this way as it neatly compiles logs of different time
Code:
adb logcat -v long > logcat.txt
This is a very nice way to get logcat.
Installing Apps
Code:
adb install %PATH OF APK%
This will install an app on your Android
For example, if my app AreeB.apk is in G:\ drive (G:\AreeB.apk)
Then I will type
Code:
adb install G:\AreeB.apk
Be sure your apk is not in a folder that has space in its name, else the command will break at space bar.
For eg:-
G:\Program Files\AreeB.apk
Mounting
However, I never found any problem in tweaking with system files with adb, but some users said that they couldn't do it, so the problem was that their system partition was mounted as Read Only(R/O)
So, it is necessary now to tell how to mount system partition as Read Write(R/W)
Code:
adb remount
It is easiest way to do so, if it does not work then
There is another method that we will discuss in ADB Shell commands section
Pushing and Pulling
For pushing,
Type
Code:
adb push %PATH TO BE PUSHED% %PATH WHERE TO BE PUSHED%
Suppose I have an app named SystemUI.apk(PATH = G:\SystemUI.apk) which I want to push in /system/app/ on my android(or in other words, install an app as a system app). Then I would type
Code:
adb push G:\SystemUI.apk /system/app/
More examples
G:\Dance.txt file to be pushed in Dance folder in sdcard
Code:
adb push G:\Dance.txt /sdcard/Dance/
OR
Code:
adb push G:\Dance.txt /mnt/sdcard/Dance/
G:\Movies folder to be transferred in SDCARD in Videos Folder
Code:
adb push G:\Movies /sdcard/Videos/
G:\system\framework\framework-res.apk to be pushed in /system/framework/
Code:
adb push G:\system\framework\framework-res.apk /system/framework/
For pulling,
push command replaces with pull and paths are swapped
Code:
adb pull %PATH TO BE PULLED FROM% %PATH TO PLACE PULLED FILE%
Example,
All system apps are to be pulled to G:\ROM\system\app
Code:
adb pull /system/app G:\ROM\system\app\
build.prop to be extracted to desktop
Code:
adb pull /system/build.prop C:\Users\Areeb\Desktop\
However, if a folder is in platform-tools folder, you don't need to type full path
Suppose if I type
Code:
adb pull /system/ system
Then a folder named system will be created inside platform-tools with all the files in system in it
If a file is in platform-tools folder, then also no need to type full path
For example,
There is an app name DeskClock.apk in this folder then, to push it to /system/app, type
Code:
adb push DeskClock.apk /system/app/
ADB Shell Commands
This mode of adb allows you to execute linux shell commands from your PC
These commands can aldo be executed through the mobile using Terminal Emulator
To initiate shell mode
Type
Code:
adb shell
You will get an prompt like this
sh-3.2#
Now you are in shell mode
adb commands won't work here and a new set of commands will work here. But we will only go in a little detail here.
Assuming you are in adb shell mode, I will only type commands that will work on shell. Note:- These commands won't work if you type them alone on cmd. But, these command will directly work on your mobile's Terminal Emulator
As these commands can also work on mobile, I am going to tell you a way of taking logcat on mobile
Type
Code:
logcat
You will see log of your device
To save this
Type
Code:
logcat > /sdcard/log.txt
A file named log.txt will be generated in sdcard
Uninstalling Applications
Code:
cd /data/app
This will change the directory to /data/app
Code:
ls
This will show the list of files in there
Suppose, there is an app named com.opera.browser (Opera Mobile) you want to uninstall it
Type
Code:
rm -r com.opera.browser
This will uninstall the app
Mounting Command:-
Code:
mount -o rw,remount /dev/block/mtdblock3 /system
Miscellanous commands:-
su: Initiates root request
du: Shows file foldrs and size
date: Shows todays date
Forgot next ones, will write later

[Q] Help using ADB to find & recover files from D4 with dead screen?

Hi everyone.
I have a Droid 4 (maserati) that suddenly died last week. I think the connection between the body and screen broke. Nothing shows on the screen, and there's no touch input available. But the device is still able to power on, reboot, and is recognizable from my Windows PC. I'd made a fairly recent nandroid backup, so I'm not in an emergency phase, but there are some files and photos I'd still like to try to recover from the broken device. Basically just files on the internal SD card. I was rooted, running stock Android on the latest OTA.
I'm not very experienced with ADB, but have started to give that a shot. I've tried various ls commands, but am stuck at a point where I get an error. Using a console (Console2), I ran ADB, then used this command:
Code:
adb shell ls -R /storage/sdcard0/
I got this error:
Code:
/storage/sdcard0/:
opendir failed, Permission denied
I'm not sure if this error is because I didn't open shell with root access. But when doing that, I run into other trouble because I'm not familiar with the linux-style commands. Another small issue I've bumped into is that when running the ls command on large file trees, the results are cut off by the console's 9999 line buffer.
Can anyone help me find a file list. Or better yet, can someone just help me pull all the data from the entire internal SD card?
Thanks!
