what do you want to do with the img? dump it or just flash it?

if you got some kind of linux distro installed, just go (in terminal) to the dir where the image file is located, and type "file filename.img" if it returns something like ext2 filesystem, simply do:
mount -o loop filename.img /mnt
and the file will be mounted on /mnt, so you can access it using cd /mnt
if it returns something like VMS Alpha executable, you will have to download unyaffs, and if you want to repackage it later on, mkfs.yaffs2,
to get the file's content, just run unyaffs filename.img, and you will have the file content right in the folder with the img file...
if you don't have a linux distro installed, you can simply get virtualbox, and download the latest ubuntu iso file... mount the file in virtualbox and install ubuntu (it's quite easy)...
oh and incase you need them some basic commands:
Code:
ls - lists current folder content
cd folder - allows you to switch to a specific folder, like if you type ls, and you get the folder android listed just type cd android... if you want to go back to your home folder, type ~/...
sudo command - allows you to run specific commands as superuser (root... you can also just switch to user root by typing sudo su, so you won't need sudo every single time)
rm file / rm -R folder/file - allows you to remove files and with the parameter -R also folders ;)
hope this helped

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

Welcome to XDA and Android! Are you trying to get help for your Nexus One? This forum here is specifically for the HTC Hero CDMA.
You will probably find better and more specific help in the Nexus One forums which are here: http://forum.xda-developers.com/forumdisplay.php?f=556

Great post, very easy to follow, thank you.

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...

Guide to install LXDE on samsung galaxy s

So 3 days of trying to install ubuntu on chroot and a little knowledge of linux and terminal, i was rather surprised to log into it and there i was, faced with an LXDE interface.
I want to thank coralic, burningbroccoli, lifehacker, josh_axeY and backfireNL for supplying the information i needed to make this possible.
So a brief overview of whats going to be done. First we will need to root our galaxy s in order to access terminal. An ubuntu image will be created and used in chroot environment by mounting (loading) it. Finally a vnc server will be setup and will be logged in using androidVNC.
So for the guide i suppose!
Guide:
First your going to need to root your phone. This is to access terminal and enter the commands required. This is taken from backfireNl's easy way to root your phone.
1. Download: 2.1 Update .zip
2. Put update.zip to root of /sdcard (not /sdcard/sd) (not on the physical SD card but the Internal SD card/Phone Memory)
3. Turn off phone
4. Hold down volume up + home button + power (tip: release the power button for half a second when you see the samsung logo)
5. Phone will reboot into recovery mode
6. Wait until you see the Recovery Screen and then release the buttons
7. With the volume down key go to the option: "apply: /sdcard/update.zip"
8. Press the home button
9. Phone will start updating
10. Phone reboots... and there you go! your phone is rooted!
So that wasnt too hard was it? Although once you have done this, you will need to download a couple of programs from the market. Goto market and download the following programs:
-Busybox
-Terminal Emulator
-androidVNC
Ensure all of these are installed as this is what you shall need in order to successfully run LXDE on your phone.
Next is the image for the install! i will post up an image file for download although for the sake of people wanting the whole info on how-to here it is.
1) login on your ubuntu machine and fire up terminal.
2) login as the super user by entering "sudo su"
3) you will be required to enter your su password, enter this and you will be logged in as root
4) In terminal enter "apt-get install rootstock"
5) One this package is all installed, enter the following code into the computer terminal:
sudo rootstock -f localhost --login ubuntu --password ubuntu --imagesize 1G --notarball --dist lucid --seed ssh,tightvncserver,lxde,expect
6)The image will be stored in the home folder. The image will need to be a .img file or it wont work. So extract the file if necessesary and rename the file so it reads "ubuntu.img"
7)Now you will need to put the ubuntu.img on the phone. The directory which it needs to be installed into is "/sdcard/ubuntu/"
8) All done for this step!
Ok so you have everything setup and ready to do the fun part! so lets get everything mounted and configured!
1)Open up terminal emulator on your phone
2)enter "su". this logs you in as superuser
3)I found you will need to make the following directories in order to work, so in terminal emulator enter:
mkdir /data/local/mnt
mkdir /data/local/mnt/proc
mkdir /data/local/mnt/dev
mkdir /data/local/mnt/dev/pts
4)enter "cd sdcard" then "cd ubuntu"
5)You will then be in the folder with the image. Type into terminal:
export HOME=/root
export USER=root
export PATH=$bin:/usr/bin:/usr/sbin:/bin:$PATH
busybox mount -t ext3 ubuntu.img /data/local/mnt
busybox mount -t proc proc /data/local/mnt/proc
busybox mount -t devpts devpts /data/local/mnt/dev/pts
busybox chroot /data/local/mnt /bin/bash
/etc/init.d/ssh start
6) Although it doesnt seem it, your now into your distro!
Okay so your into your distro but it looks all horrid and "text based". wouldnt it be lovely to see a proper desktop? so lets go!
1) enter into terminal "apt-get install x11vnc" this installs x11vnc to your phone. This may take a while depending on how your connected to the net
2) once x11vnc is installed, type "x11vnc -storepasswd" and enter a password. It will ask to verify the password so enter it again, then enter "y" to setup a password for it
3) first enter "vncserver" to initiate the server on your distro. For some reason without this, androidVNC will start to connect then crash
4)finally enter "x11vnc -usepw -find"
now your x11vnc is setup using a password hooray! last step in this guide and you will be away in no time! So is everyone ready?
1)hit the button on the bottom to return to the desktop but keep terminal emulator running
2)goto androidVNC and enter the following:
Nickname: root
Password: (whatever password you setup in x11vnc)
address: localhost
Port: 5900
color format can be anything, i set it to 4 bpp and use local mouse pointer
3)Simply click "connect" and viola! welcome to your impressive lxde environment!
This has been done before although i tried to do every step, base it around the phone as much as possible so no connecting to the computer.
any questions or problems i will try my best to help you guys, and thanks for the guys who helped me on this voyage.
i will write a bash script soon to try and incorporate as much of the manual typing in as possible
good luck!
Things which need to be done:
Upload image: Completed! - http://www.megaupload.com/?d=H55O5UEM
Bash script for terminal emulator: Completed, needs to be uploaded
Bash script for setup process of terminal emulator: Not completed
Startup script for image: Not completed
Youtube video: Not completed
Include internet browser and x11vnc in image file: Not completed
If anyone has any recommendations on how to make the process easier please let me know and i will try my best

Good to see the info consolidated into one post!
Cheers for the shoutout.

no probs your information helped me soo much, i just thought it would be good for someone to goto a post and go "oh yeah thats how to do it" instead of going to loadsa websites

i will try it very soon, thank you.

awesome!
When will you post your img file? I'll have a try.
I have no ubuntu installed, I'm using ArchLinux.

okay ive written a bash script to automate most of the process although there are a few things i could tweak before im fully happy
i have also posted a youtube video to demonstrate how easy it is! the first post will be updated with the link.
people ask me the reason for doing this and i have 2 replies:
1)to show the true potential of this phone (and working in a phone shop it really works)
2)for development purposes. Things like this are the next step in unlocking the true potential of the phone
lijgame: Im just uploading it now for you

Good work, will give it a try. And what about any browser ? Like firefox ?

hi.
okay so this is installing ubuntu into a chrooted environment and vnc'ing to it.
does anyone know if it is possible to blow away android and install pure debian on it? does anyone know of a hardware list on the sbc in this thing and what sort of support one might need to hack in to get a such a thing to work?

I will apologise now for the delay in image upload, the image file is 1gb and im having trouble finding a place to upload it.
In terms of installing a clean debian would need more than just a straightforward port. You would be looking at making an environment which supports the arm architecture, porting all of the drivers over, creating an option to support telephony, messages and gps too. If you wanted a debian environment it would probably be best to either run it like how the n900 does or getting a distro of it which is specifically made towards mobiles and modifying it.
Although you have an extremely good point there! Tell you what, once ive got everything running on here i will have a look and see what i can do in terms of atleast getting a debian shell running or a limo version

Just create zip/tar-ball of img file and it will become around 300MB. Then you can upload it on multiupload (or megaupload/rapidshare/mediafire).
I just created that image too and will be testing on my Galaxy S soon, so if its working for me then I will upload my image too.
Thanks for your good work

haha i shouldve really thought about compressing the file really
this will be a pre-image im just working on getting a better image with optimization, x11vnc and firefox

okay guys the first post is edited with the image for the install.
http://www.megaupload.com/?d=H55O5UEM
I am currently in the process of playing about with images to include everything you need, so soon enough i will have an image with everything you need to get started

Tnx for the credit!

Ubuntu image is uploaded and ready to go, im currently working on a better image so when ive finished that, it shall be released.
Also i have recently installed an internet browser and it is functioning properly. I will post screenshots soon

The image is only 11MB and is corrupted
Moreover, I tried to mount my ubuntu.img to /data/local/mnt but it is giving error (sort of -> loop back device can't be mounted: No such file or directory) although I created and checked /data/local/mnt directory which exists

Try creating a second loop device with: mknod /dev/loop2 b 7 0

im guessing because the image is corrupt, your unable to mount it.
I have just uploaded my bash script making it easier to mount each time.
bash script: http://www.megaupload.com/?d=CEU6R5J4
Image file: http://www.megaupload.com/?d=H55O5UEM
ensure you have made the directories explained in my first post.
pop the hsetup.sh file inside /sdcard/ubuntu (along with your image)
then fire up terminal emulator and type:
su
cd sdcard
cd ubuntu
sh hsetup.sh
This mounts everything for you and logs you into LXDE, all you need to do after is type in:
/etc/init.d/ssh start
vncserver
x11vnc -find
Then log in using androidVNC
i will attempt to upload the file to another location and i will test the image file to ensure its not a compression error

i apologise, ive just looked at the zip file and it is corrupt.
just compressing a new one and i will upload it

[Error] Unable to apply PUSH Command in ADB

Hello mates,
I am trying to Copy the BUSYBOX file to my /data/local/bin directory. But when i use the 'push' command it say adb: command not found. Hereby i have attached the image of my terminal.
Would you please help me in copying my files to the directory "/data/bin/local"
Also, where should i put the files which i need to copy. Eg. Since i need to copy 'busybox' to the /data/local/bin/, should i put the busybox in my Desktop, i.e. /home/android/platform-tools directory?

You should've not run the command from within the adb shell. Just go to the tools folder and type "adb push busybox data/local/bin" ofcourse without the ""
The busybox should be indeed be present in the folder from witch you run adb, in your case the "tool" folder.
Good luck!

Make ROOT Permanet / System Read and Write to all Android ROMS for Tenderloin

Extracting ramdisk image to change fstab.tenderloin to make system read and write allowing permanent root access using any ROM ever created for the HP Touchpad.
I am using Ubuntu 18.04.1 LTS 64-bit (All the software is open source and free, you can get the packages necessary for your distro)
Create a folder in /home (root) name it hpboot ( on the PC ) all work is done on the PC.
Open the custom ROM zip file and extract boot.img to the created directory hpboot
Open Terminal in the hpboot directory, all the commands needs to be enter there.
Text beginning with –>># are for information only. Do not paste into the Linux terminal window.
–>># The following will extract images from boot.img file located in the hpboot direcory.

–>>#You should have free space on your boot for both images. At the boot screen you will have the option of Android (with no permanet ROOT access) and Android_RW (RW System), you need to install SuperSu. You can use any of the two options or delete uImage.Android and then rename uImage.Android_RW to uImage.Android for one boot option.
You do not need to re flash the ROM, you can add this boot file and use it with your current installed working ROM.
The process works for all boot.img created for the HP Touchpad. If you have a ROM and would like to have system read and write access then you can do this.
Hopefully a Linux Guru will create a script for this, which will automate the process to 3 seconds!

I like tinkering with my TP but I am running @Windows 7 on a 32 bit.. any suggestions?

Android is base on Linux OS.
Install vmware player and run ubuntu as a virtual machine, both are free.

Here's a shell script that automates the process (rename the extension from .txt to .sh). Put the script and boot image file in any directory and type
Code:
./rwcreate.sh
If it doesn't execute, it probably needs its permissions changed.. Right click the file you created, select 'properties'. In the properties window, select "Permissions" and check "allow executing as ..." or type
Code:
chmod +x rwcreate.sh
in a terminal window

Thanks for your help and dedicating your time to make it easier for others.
I made suggestion to the script on correcting an error, on DU forum.
Now is just a click to get it done, but if we were in a perfect computer world, it could be even easier as to connect the HP Touchpad to PC using USB.
Then run the script and everything is complete!
Using adb pull command to get (boot.uImage) from hp boot directory, to PC.
Changes are done as per script.
adb push command new boot.uImage to hp boot directory, all done!
But making it easier, will make it more complicated and having to install more software and confusing!
