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

GUIDE : How to modify the cust.img

Hey there.
Does anyone knows how to modify the cust.img file of the latest official 2.3.5?
I want to remove some firmware apks (swype to install another version which support greek).
Thanks!

Hi I got this information from That-Guy:
1. Download Slitaz Linux 3.0 Live CD
2. Open terminal
3. Copy cust.img from phone to /home/tux folder
4. mkdir tmp
5. mount cust.img /home/tux/tmp
6. cd /home/tmp/hw/default/app
7. Delete apk files what you don't want
8. unmount tmp
9. Copy cust.img from /home/tux folder to phone

Thanks. I did the following and worked:
In Linux (ubuntu 10.04):
1)copy the cust.img file from your .cust_backup/image folder of your mobile somewhere in your computer (ex Desktop)
2)open a terminal and type sudo su (root permissions) and then your computer password
3)Go to "somewhere" : with command: cd somewhere (ex cd ~/Desktop )
4)type at terminal mount -o loop cust.img /mnt/
5)type sudo nautilus . This should open you a navigation window.
6)navigate to: file system --> mnt/
inside the hw/default/app are the apks of the default cust.img.
Edit it as you wish.
to unmount type at terminal (with root permissions again): umount /mnt/
you are ready to copy the cust.img back to your phone and replace the old one

can someone give us a clear cust.img and the apps to a folder in order to let us choose which of them we want to install?
I'm not so familiar with linux OS and i am afraid to do it on my own. :/

How to flash a custom rom via Odin

Hi guys. How can I create a flashable tar.md5 file via Odin? I need it to install a custom rom.. For first I installed the rom via recovery, then I made a backup of the /system partition using dd command line. After made the backup with the ext4.img extension (like stock firmwares), I converted it in tar.md5 using these commands on Ubuntu 14.04:
Code:
tar -H ustar -c customrom.ext4.img > customrom.tar
md5sum -t customrom.tar >> customrom.tar
mv customrom.tar customrom.tar.md5
Then I flashed the tar.md5 file via Odin but it gave me always fail.. There's anyone that could help me?

[GUIDE] Extract Samsung *.tar.md5 files on Linux

Hey. While trying to port a TouchWiz ROM, I came across tar.md5 files. For some reason, every guide to open this format assumes you're using Windows. I use Linux Mint, so it was a bit of a problem. I found the solution, and thought I should post it here.
Materials required:
Android Kitchen
Linux distro with p7zip
Basic Terminal knowledge
Procedure:
1. Download Android Kitchen here: http://forum.xda-developers.com/showthread.php?t=633246
2. Download and install p7zip (for Ubuntu-based distros):
Code:
sudo apt-get install p7zip p7zip-full p7zip-rar
3. Open a Terminal in the directory where you have your tar.md5. Do:
Code:
7z e SomeReallyLongNameHowDoesSamsungRememberThis.tar.md5
And wait for the shell prompt to appear again. When it does, go to Android Kitchen's original_update folder and paste the boot.img and system.img that were extracted there.
4. Open a Terminal in Android Kitchen's directory. Do:
Code:
./menu
1
(just press enter, type nothing before it)
(type number corresponding to "system.img and boot.img" and press enter)
When it asks you for your password, give it the password. It needs that for mounting the IMG file.
Now your /system folder is in WORKING_whatever, and you can make a ZIP from Android Kitchen. Done.

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.
–>># Copy and paste each individual line in the Terminal window one by one and wait until each command finish processing.
dumpimage -i boot.img kernel.uImage
dumpimage -i boot.img -p 1 ram
dd if=ram of=ramdisk.img.gz bs=64 skip=1
gunzip ramdisk.img.gz
mkdir ramdisk; cd ramdisk
cpio -i < ../ramdisk.img
–>>#The ramdisk files are uncompress in the hpboot/ramdisk directory
–>>#Open file fstab.tenderloin using (text editor) change mnt_flags of/system ext4 from ro to rw
–>>#Look like this when change from (ro ) read only to ( rw ) read and write.
–>>#<src> <mnt_point> <type> <mnt_flags and options>
–>>#/dev/store/cm-system /system ext4 rw,errors=panic
–>># Save and close the fstab.tenderloin file
–>># The next 3 steps will repack the files into the ramdisk and merge Kernel to create the finish boot image.
find . | cpio --create --format=’newc’ | gzip > ../ramdiskRW.img
cd ~/hpboot
mkimage -A arm -O linux -T ramdisk -C none -a 0x00000000 -n “TENDERLOIN RW SYSTEM RAMDISK” -d ./ramdiskRW.img ./ramdisk.uImage
mkimage -A arm -T multi -C none -n “Tenderloin RW System” -d kernel.uImage:ramdisk.uImage uImage.Android_RW
–>>#Boot the touchpad into TWRP, connect to PC, copy uImage.Android_RW to the external Micro SDCard.
–>>#Select MOUNT and touch Boot, go back, touch Advanced, File Manager, touch external_sd, select uImage.Android_RW, touch Copy File, touch boot, touch select Current Folder.
–>>#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!
