Is there a list somewhere for the commands because i tired to do the "dir" to get a list of files in the folder but it work. (on terminal or adb shell).
* Also what is the best file manager? Is there anything that has a password so that other people cant get into it?
'ls' is the unix command to list contents in a folder
Ok thanks. just been a long time since i messed with Linux shells i guess i should get my books out and start reading again
Android's Linux commands
although he got the wrong command for list files, he raises a good point, the android linux is far from having all commands other linux system have - does anyone have these documented somewhere? what it has and what it doesn't have?

if you are running jf 1.31 then you have busybox installed.. google busybox and you will find out all the terminal commands you can run from your phone terminal or over adb shell.....

ls /system/bin
ls /system/xbin
ls /system/xbin/bb
that should give you a fairly complete listing of the commands available.

I just noticed this myself. I need to remove a symbolic link and recreate it by "unlink" and "rm" dont' seem to work. Is there a busybox command that will do it?
A quick google search brought up this annotated list for those new to these commands:
http://www.busybox.net/downloads/BusyBox.html
JF Thanks for that, I was looking for that folder earlier and could not find it for the life of me. Blame it on drowsiness ...or just plain not wanting to be at work.
That list is only valid for modified Android. Stock Android runs toolbox, which has a much neutered list. Aside from JF's method, you can also look at the tpolbox links in update-script of an official update.zip
Hmmm.. does this mean overclocking is possible? Not that we "REALLY" need it right now but.....
adjtimex [-q] [-o offset] [-f frequency] [-p timeconstant] [-t tick] Read and optionally set system timebase parameters. See adjtimex(2).
Options:
-q Quiet
-o offset Time offset, microseconds
-f frequency Frequency adjust, integer kernel units (65536 is 1ppm)
(positive values make clock run faster)
-t tick Microseconds per tick, usually 10000
-p timeconstant
If you read any manpages on the command you would see that it's for correcting system clock drift.
If you type in "busybox" (without quotes) it will give you the list of commands. Enter "<enter command here> -d" for a description of the command you entered. Hope this helps...
"busybox --help" anybody? i thought the bb we had on our androids was not supposed to be the full busybox?

Hi,
I have made a little .sh script as a test.
But when i use terminal emulator to run it i get the 'permission denied' error even though my phone is rooted. Please tell me what to do to run a .sh file on my phone.
Script:
#!/bin/sh
echo hi
Thanks in advance. Any help will be greatly appreciated.
i think that if you do:
su (to get superuser privileges)
sh your_script.sh
might work....
alternative is to install gscript and put your script in the gscript folder on sdcard....
The console needs to be granted superuser access, then ran as sh script.sh or bash script.sh. afaik at least. Youll probably have to use su like the person above said.
I did the su command. But i still can't open it. All other commands work.
Ok so it sorta worked.
I used the cd command to get to the file.
I used su command.
Then i typed sh script.sh .
Nothing happened, no echo or anything, just a new line with # on it.
What's happening.
Btw thanks for the replies.

Maybe stating the obvious, but did you CHMOD the file to be +X ? Use Root Explorer or chmod at a SU capable command line to change the file mods to allow execute.

This should be the solution. X is the execute bit. Basically without that bit set on the file permissions, the OS won't allow that file to be executed as a program.
chmod +x filename.sh
Try running that command in terminal emulator and it should clear things up.
Sent from my Inspire 4G using XDA App
I used that command and it said 'bad mode'.
It still doesn't work.
If you are running the script with this:
Code:
sh script.sh
then the executable bit doesn't need to be set in order to execute it, since you are specifying 'sh'. If you were trying to run it with this:
Code:
./script.sh
then it would require the executable bit to be set.
In an attempt to answer the question, where abouts is your script saved and which user owns it? Just as a quick test on mine, I made a script named test.sh (containing the same lines as yours) on the root of my sd card, cd'd to it and ran sh test.sh, and that seemed to work. That script ended up being owned by 'system'.
As a test to make sure sh is behaving, can you run the following from the terminal:
Code:
sh -c 'echo hello'
EDIT: note that all of the above was run as a regular user, not root.
Yeh it said hello when i did the command you said.
It must be a problem with the file in some way then. Can you run the following from the folder that your script is in and give the output?
Code:
ls -l | grep script.sh
Also, what did you use to make the script - terminal in Android, or adb'd it from your PC etc?
(Aside: just a thought, you probably can't do chmod's on sdcard files if it's formatted to FAT32 since FAT32 doesn't understand Linux permissions)
you can also try an app i found some time ago. SL4A
I made the file with silveredit. Just renamed .txt to .sh.
Btw i got it working with gscript, thanks for everyone's help

it's because android doesn't know about these command, this is a native linux command, try to install busybox, edit your script like this
Code:
busybox ifconfig usb0 192.168.137.2 netmask 255.255.255.0 up
busybox route add default gw 192.168.137.1 dev usb0
busybox setprop net.dns1 8.8.8.8
busybox setprop "net.grps.http-proxy" ""

Even though your device is rooted, android environment won't allow applications to execute 'sh' commands.
As android security architecture says, applications run within a secured execution space inside Application Sandbox, sh execution can bypass this security.
If there are any exceptional cases where few devices allow 'sh' execution, well... OEM's needs to be reviewed again.

Maybe you can try the method that I have specified and check whether it works

You have to put the script somewhere that it has permission to execute from, copy it to /data/local/tmp first. Then in your terminal run each of these commands;
su
cd /data/local/tmp/
chmod 0755 MyScriptName.sh
./MyScriptName.sh
INFORMATION
This guide is intended to make a full backup of your android phone (the entire memory block with all partitions) or a single partition (including sdcards, etc) directly to your computer, in either
Block level (with dd): for single partitions or whole memory block (all partitions in one piece). The backup always has the same size which is the size of the partition.
File level (with tar): only for individual partitions. This only includes files and folders, so occupies much less space, depending on how much filled is the partition.
It can be done with the phone powered on or from ClockWorkMod Recovery (from both ADB works, while in Fastboot doesn't so won't apply). Unless specified the commands meant to be used from Windows. For Linux and Unix is similar.
REQUIREMENTS
Rooted Android Phone
Busybox installed on your phone
If you are using Linux / OS X you have native tools, for Windows download Cygwin, and install with it netcat, pv and util-linux. Get them from Cygwin's setup.exe
ADB installed.
Make sure adb.exe is in your windows' path. See here and here, or use Path Manager.
Android phone with USB Debugging enabled, and the proper drivers installed on Windows so the phone is recognized. Typing 'adb devices' on a terminal should show your device.
PARTITION IDENTIFICATION
You now have to identify the partition or block device that you want to backup. For a single partition you can use either tar or dd, while for the entire memory block you can only use dd.
For example, on Galaxy Nexus you have the list of partitions here and for Galaxy S2 here.
Usually on android, the entire block containing all partitions is located at /dev/block/mmcblk0 and the data partitions is a subpartition of it. You can push parted with GPT support to your device and see all information on a partition or block.
Whole phone memory -> /dev/block/mmcblk0 (may vary, in some phones this is the sdcard)
Subpartitions -> depends on each device. Usually at /dev/block/platform/dw_mmc/by-name/ there are listed by name linking to the real device.
Back up of the whole memory block (via adb)
Connect the phone in ADB mode and unlock the screen.
Open one Cygwin Terminal and enter (replace mmcblk0 if needed):
Code:
adb forward tcp:5555 tcp:5555
adb shell
su
/system/xbin/busybox nc -l -p 5555 -e /system/xbin/busybox dd if=/dev/block/mmcblk0
You will see the cursor blinking at the left. Now the phone is waiting to send the block over the network.
Open another Cygwin terminal and type:
Code:
adb forward tcp:5555 tcp:5555
cd /path/to/store/the/backup
nc 127.0.0.1 5555 | pv -i 0.5 > mmcblk0.raw
You will see how the image size is growing until it finishes. Now you have the whole phone backed up in raw format. You can see the contents of the GPT partition with gptfdisk tool, available for windows, linux and such. See official website and sourceforge to get it. You can do it the same from ClockWorkMod Recovery but you have to mount first the /system partition since the busybox included with clockworkmod does not come with netcat and you have to use the one from the system partition.
With further linux tools you could edit or extract single partitions from the whole block.
You can use adb via wifi as well with applications like WiFi ADB.
Back up of the whole memory block (via wifi)
Original post: [Q] Nandroid directly to computer w/o sdcard
We need to install a FTP server on the computer or the other device, configure a user with a password if we want to, and set some port. It uses by default 21 but this example uses 40. We must set a home dir for the user with write permissions.
Usually is a good idea to put myfifo in /cache not in /data because we may overwrite sensitive data in case we want to use that raw image for data recovery.
Open one Cygwin terminal
Code:
adb shell
su
mkfifo /cache/myfifo
ftpput -v -u user -p pass -P 40 COMPUTER_IP block.raw /cache/myfifo
Open another Cygwin terminal
Code:
adb shell
su
dd if=/dev/block/mmcblk0p12 of=/cache/myfifo
Tips:
- Fifos only can be made on linux native filesystems, for example on a FAT partition is not possible.
- Reading from a partition does not modify it.
Now check on Filezilla Server the speed
Back up of the whole memory block (USB tethering, Wifi tethering)
To use tethering you have to disconnect the computer from all networks and connect it only to the phone with the type of connection you want.
Once you connect it, you can view the IP of the computer and the IP of the phone from connection properties. The ip is the computer ip and the gateway is the phone's ip.
Wifi Tethering: Computer <---Wifi---> Phone <---3G---> Internet
USB Tethering:
Computer <---USB---> Phone <---Wifi---> Internet
Conputer <---USB---> Phone <---3G---> Internet
This is exactly the same as via wifi, except that the transfer speed is much higher because the computer and the phone are directly connected, instead of using a router as a gateway. In this case, the gateway is the phone. USB tethering has the highest transfer rate.
Back up of a single partition (raw = every bit of the partition)
It is exactly the same as the the previous but replacing mmcblk0 by the corresponding partition. You can use in this particular case several software to read the partition from windows, depending on partition filesystem: DiskInternals Linux Reader, Ext2Read, Ext2 File System Driver for Windows, Ext4Explore, plugin for Total Commander and ImDisk Virtual Disk Driver. You can also use recovery software on individual partitions like Recuva in combination with VHD Tool or command line tools included with operating systems.
Back up of a single partition (tar = only files and folders)
In this case, you need the partition mounted. To see the list of mounted partitions type on Cygwin Terminal
Code:
adb shell mount
Now you need to know where is mounted the partition you want to backup, for example the firmware is mounted on /system, which is the ROM.
In this case you will have to open three terminals, because of android limitations:
Open one Cygwin terminal and create a fifo, in /cache, for example, and redirect the tar there
Code:
adb forward tcp:5555 tcp:5555
adb shell
su
/system/xbin/busybox mkfifo /cache/myfifo
/system/xbin/busybox tar -cvf /cache/myfifo /system
We have to do it this way because redirecting the tar to stdout (with - ) is broken on android and will corrupt the tar file.
Open a second Cygwin terminal and type:
Code:
adb forward tcp:5555 tcp:5555
adb shell
su
/system/xbin/busybox nc -l -p 5555 -e /system/xbin/busybox cat /cache/myfifo
Open a third Cygwin terminal and type:
Code:
adb forward tcp:5555 tcp:5555
cd /path/to/store/the/backup
nc 127.0.0.1 5555 | pv -i 0.5 > system.tar
You can browse the tar file with Winrar, Total Commander, PeaZip and almost any compression tool. Note that you shouldn't extract files or edit it since the tar format saves the permission and owner data for each file, that is lost when extracted to FAT / NTFS partitions and you will mess things when restoring.

mohsyn said:
On newer android versions (Im on 7.2) data folder has a folder media which is link to sdcard and one ends up backing up entire sd card. I had a 64gb backup which wasn't necessary
In order to avoid skipping the media folder i had to do some trial and error because busybox tar command is not completely the same as GNU tar.
Would appreciate if you can mention it in the mail guide to use the following command to backup /data folder without copying sdcard files
In first terminal
tar cv --exclude data/media/0 -f /cache/myfifo /data
in 3rd terminal
nc 127.0.0.1 5555 | pv -i 0.5 > data.tar
no change in second terminal

You've done almost everything! But you skipped the section "make sure adb is in your path"
Probably you have adb.exe in the path
Code:
C:\Program Files (x86)\android-sdk\platform-tools\adb.exe
So you have to just add it to the Cygwin's path (would be better if you had added it earlier to the windows' path and cygwin will import it automatically but it is ok)
Code:
export PATH="/cygdrive/c/Program Files (x86)/android-sdk/platform-tools":$PATH
Remember to backup the path previously if you want.
Code:
echo $PATH > mypathbackup.txt

You don't have installed pv and netcat on cygwin. Run the setup.exe and install them.
If you run
Code:
whereis pv
whereis nc
should give you some path (in cygwin) but applies similar inside android.

No idea what you may be doing wrong
Listen, I appreciate the guide, and it being basically the only one which popped up in google results, I can't gripe too much, but... you really, really need to make it more clear.
The point of a guide is to help a large group of people with varying degrees of knowledge (and if it's a guide targeted at a specific group of people, i.e tech savvy, then it needs to be indicated as such).
With that working definition in place, it follows that you should be as specific as possible; think of *everything*. By doing so, you not only avoid headaches for the people reading the guide, but for yourself as well since you don't have to reply to comments which might've otherwise been avoided.
I would post a question, but I'll probably have figured this out (with a good 1+ hours of searching no doubt) before anyone responds.
Here are some examples of what could be more specific:
"ADB installed." - what is ADB? Where's the link? It's not reasonable to assume people use these tools on a regular basis or remember them.
"You can push parted with GPT support to your device and see all information on a partition or block." - okay, so we know what it does but not how to install it or use it.
"ADB mode" - is this important? What is it? Not sure because it was glossed over.
These are just some examples. It's not the most horrendous trespass ever committed, but definitely annoying. Just spell it out from one step to the next, it works far better than topics with subheadings and unintuitive concepts being assumed as general knowledge on the behalf of noobs like me.
Edit: I'm just going to take everything off my SD card, use nandroid, and then copy the nandroid backup to computer as well. Please improve the guide, thanks.
Greatly appreciate this!
For me, a long-time UNIX and Linux administrator, this little guide was a breath of fresh air. Scandiun, *Thank You* for putting it together. It makes perfect sense to me -- just treat the phone as the linux machine it is. I'm becoming convinced that most of the more recent "developers" hanging around the android community have never used a linux machine before -- they don't seem to know what's going on, they go way out of their way to write overkill tools to do things clumsily that can already be done cleanly and quickly from the command line, and then they wrap those tools in so much mystery, black magic, and script-kiddie terminology that I can't figure out what they do either, and I certainly don't trust them doing things to my phone.
For example, I've got a new Galaxy S3, and just wasted a whole day digging around on xda, reviewing all of the "kewl rooting mods" until I got sick of it. Why the *heck* are people flashing entire partitions just to install a setuid /system/xbin/su on these devices? The rooting method I wound up using was dirt simple -- just find an rc exploit and use it to install an 'su' binary, by typing a few commands via adb. I used a variation of the exploit mentioned in http://seclists.org/fulldisclosure/2012/Aug/171, and elaborated in http://forum.xda-developers.com/showthread.php?t=1790104, http://forum.xda-developers.com/showthread.php?t=1792342, http://galaxys3root.com/galaxy-s3-root/how-to-root-u-s-canadian-dual-core-galaxy-s3-on-mac-osx/, and http://forum.xda-developers.com/showthread.php?t=1827518. If you are a UNIX person, you'll recognize what's going on with that exploit and be able to come up with something that suits your own needs. If you aren't a UNIX person, then you'll be completely lost. Sorta like this guide.
For anyone who doesn't yet know what adb is, or who's never used standard UNIX/Linux tools like dd, netcat, gparted, or busybox, I agree that this guide is not only not going to help you, but may actually aid you in shooting yourself in the foot with extreme efficiency. But please don't criticize or nag the OP in return for helpful advice freely given. You won't learn much about UNIX tools on an Android-related web site in any case. I recommend starting with a Linux systems administration book -- the Nemeth series is always good. But if you do take that route, you need to expect to take time to learn the basics.
Absolutely beautiful!
Thank you for this work. I was able to recover deleted files from my Galaxy Nexus' internal memory using this technique. I made a [GUIDE] using most of what you accomplished here: http://forum.xda-developers.com/showthread.php?p=34185439
Thank you, thank you, thank you! It can't be said enough. I had family photos that I would not have been able to reproduce. Much love to you and yours!

nc is an abbreviation for netcat. On Cygwin, you choose to install either, but for the original, written by the *Hobbit*, that allows direct execution of commands with -e and -t, you have to uncheck "Hide obsolete packages" on Cygwin's setup.exe.
The two of them are here:
Netcat 1.10 (netcat.traditional): http://www.netgull.com/cygwin/release-legacy/netcat/
Netcat 1.107 (netcat.openbsd): http://www.netgull.com/cygwin/release/nc/

parted seems to not work fully with Samsung galaxy Y = SGY proprietary rfs filesystem
on SGY mmcblk0 gives you the sd card, not internal storage with android.
backing up my sd card was a thing I could even do before I read this (lol)

Can you post where is your whole memory block then or even the PIT file for that phone? You have an example here:

I don't know where the "whole memory block" is or what it is. is it internal storage = NAND ?
here is the pit file:

Yes it is the NAND. See your pit analysis here:

OK

very interesting tool.
but how do I backup NAND in one piece on SGY ?
mmcblk0 = sd card
???blk0 = NAND
it must be somewhere ...

Is almost sure that is under /dev/block. Please post the output of
Code:
ls -lR /dev/block
I have successfully rooted my HTC Wildfire S but now I am trying to reinstall HTC Mail after deleting it in error!
I am using the adb command to copy files from my sd card to the system folder on the ROM e.g. adb push/sdcard/Mail.* /system/app. However, when I press the enter key I just get a list of the adb commands and switches and it doesn't copy the files across.
Any ideas as to why this may be happening? My Android Debug version is 1.0.26
If I could just download the HTC Mail app and install as usual that would of course be preferable but I think it's only available as a factory install. I've tried the K9 mail app but I have a feeling there is a connection timeout bug that means it doesn't disconnect from the POP mail server for ages after it's 'pulled' messages. I've had many senders complain they have message failed errors when they try to send to me but they haven't had them since I uninstalled K9 and started using HTC Mail. And in case you're wondering, I started using K9 because the old version of HTC mail would not save my SMTP settings but the new version is OK.
Thanks for any help.

Looks like you've used the wrong command.
adb push framework-res.apk /sdcard/framework-res.apk
adb shell dd if=/sdcard/framework-res.apk of=/system/framework/framework-res.apk
Obviously swap framework-res for your apps name.
adb command fails
Thanks XperienceD. Will try your syntax later.
adb command fails
XperienceD
The syntax you suggest is not compatible with the adb I'm running i.e. dd is not a vaild switch. I'm trying to use adb to reinstall an app to an HTC Wildfire S.
From what I've read elsewhere the syntax I used should work but doesn't...

Did you start by mounting the system - adb shell mount -o remount,rw -t yaffs2 /dev/block/mtdblock2 /system ?
Hi,
I have a Verizon Samsung Galaxy S3 SCH-I535.
I have rooted it using this guide. I realize there was probably an easier way to root it, but regardless it worked fine, I have root access.
The phone is returned to factory condition, pretty much, but I need to recover data from it. There is no microSD card.
I have tried to follow this guide for recovering the internal memory without being able to transfer the internal memory to my computer. I'm stuck at the data transfer point.
I've followed the guide to the letter, except I'm trying to recover memory block /dev/block/mmcblk0p23 (and I've also tried simply /dev/block/mmcblk0), so I've modified the commands to the following:
Code:
adb forward tcp:5555 tcp:5555
adb shell
/system/xbin/busybox nc -l -p 5555 -e /system/xbin/busybox dd if=/dev/block/mmcblk0p23
And in the other Cygwin terminal:
Code:
adb forward tcp:5555 tcp:5555
cd /nexus
nc 127.0.0.1 5555 | pv -i 0.5 > mmcblk0p23.raw
Screenshots attached. I'm not sure why, but the data stays at 0 B/s no matter how long I let it run.
Am I missing something? Am I doing something wrong? I've installed Busybox on the phone (it's in xbin, not bin, hence the modified syntax). Cygwin (with pv and util-linux), Netcat, and ADB on the computer. USB debugging mode is enabled on the phone (ADB connection works).
I really need to pull the internal data off of this phone soon... can anyone help me get this figured out please? Thanks.

Are you running cygwin as an administrator? Are you requesting superuser access by typing su after adb shell?

Hi billard, thank you for the response.
I have tried using su (# prompt instead of $ appears, so yes it is working) after adb shell, with no change in results.
I hadn't tried running Cygwin as administrator, but just made that change as well to see if it would make a difference. Still no dice.
I've also ensured NTFS permissions in the /nexus folder (C:\Cygwin\nexus) are "full access", and there are no issues there, either. Screen shot attached of latest attempt (Cygwin is "run as administrator"/su command used).

Don't know why I didn't catch this sooner. But what lead you to believe it was mmcblk0p23 you needed to use? I'm not sure exactly what that partition is(if it exists) but the data partition is mmcblk0p15 I believe on the US S3's. Try that

I was guessing it was the highest numerical memory block, and /system/dev/block ls lists 23 as the highest number.
I just tried with mmcblk0p15 and have the same exact frustrating 0 B/s indefinite results. -_-
