I've searched and can't seem to find a way to solve the issue.
I'm trying to install a metamorph to make the engadget widget transparent and I need to movie the apk from /data/app to /system/app (according to this post: http://forum.xda-developers.com/showpost.php?p=6319426&postcount=102)
In doing so I've received the cross-device link error.
I've tried these sets of commands:
(note: I am typing the below commands from memory, I got them by searching and I typed them word for word even if the commands below may be incorrect)
Code:
mount -o rw,remount /dev/block/mtdblock5 /data
mount -o rw,remount /dev/block/mtdblock3 /system
mv /data/app/name.of.apk /system/app
HTML:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
mv /data/app/name.of.apk /system/app
I've even tried using root explorer and while it shows a progress bar and says it's moving the apk, nothing happens.
I've tried rebooting the phone and the issue still persists.
Can anyone help? Thanks!
Go into /data/data and /data/dalvik-cache and delete all files affiliated with that apk and reboot, the move a copy of the apk file to /system/app, fix permissions and reboot.
let me know if this works.. i'm curious. i had to resort to
Code:
cat /data/app/name.of.app.apk > /system/app
to get it to work. i read somewhere that mv doesn't sit well on android 2.1. cat worked fine, but maybe i didn't realize if mv required the data & dalvik-cache to be wiped.

That didnt' work either.
To the both of you, thanks for the help so far. I appreciate it.
:-/
Try putting the apk file directly on the c: drive, go into adb shell, do command: mount /system, then command: exit, the command: adb push c:\name of app.apk /system/app
That works for sure, but I'm still left wondering why I can't move a file from one directory to another on the device.

hmm.. that worked, but mv and cat didn't? that's really weird.
I am also receiving this message. I am trying to:
mount -o remount,rw /dev1/block1/mtdblock4 /system
# mv /sdcard/bootanimation.zip /system/customize/resource
failed on 'bootanimation.zip' - Cross-device link
any ideas??
This workshop was held in #android-learning on irc.freenode.net by XDA Member Adrynalyne. All credit to him for this guide, I simply am taking it and turning it into a guide. Here we go!
You can find the raw IRC log here
Good evening folks, and welcome to my ADB workshop. This is by no means a full explanation on the subject, but more of a crash course to help folks get up to speed, and get more from their devices. There may be some things you already know here, so please be patient and respect those who do not.
Reference Files
http://adrynalyne.us/files/How to install adb.pdf
http://adrynalyne.us/files/Using ADB.pdf
So, lets just start with the basics.
What is ADB?
ADB stands for the android debugging bridge and is used for testing and debugging purposes by developers.
However, we like to get more out of our devices, and its a great way to fix things.
Knowing adb can mean the difference between a paperweight and a working phone.
So, to start with, we will look at installing ADB.
Generally speaking, the Sun/Oracle JDK is required to run all SDK functions.
ADB is but one tool in the SDK arsenal.
So, we begin by downloading and installing the JDK. This can be found here:
https://cds.sun.com/is-bin/[email protected]_Developer
Choose your OS, download and install. I recommend that 64 bit users use the regular x86/32 bit version as well.
Moving ahead, we download the Windows sdk from here:
http://dl.google.com/android/installer_r08-windows.exe
Due to already installing JDK, you won't be stopped by the install process.
Now, if you notice, I installed it to:
C:\android-sdk-windows
I did this because it makes things easier when setting up path variables.
I encourage everyone to do the same, but obviously it is not required.
So, this SDK is handy, but is only good up to 2.2. We want the latest and greatest! (Well I do)
So, we navigate to:
C:\android-sdk-windows\
and we run SDK Manager.exe
If you notice in your PDF file for installing adb, you will notice that you can update, and I made a choice not to include earlier sdk versions.
I won't go into full detail on that, but depending on the version of SDK you have, 8 or 9, it WILL make a difference in using adb.
By default, for version 8 adb.exe resides in C:\android-sdk-windows\tools
By default, for version 9 adb.exe resides in C:\android-sdk-windows\platform-tools
We will assume version 9 in this guide
Really, the SDK is installed and adb is usable right now, but in my humble opinion, its not enough
I like the ability to use adb in ANY directory on my machine.
To do this, we edit Windows's environment variables.
Specifically, the system path.
To do this, we click on start, or the orb (depending on OS), and right click on Computer, left clicking on properties in the menu.
If its windows XP, I believe it brings you into advanced system properties immediatly. Vista and 7 need a second step.
On the left hand side, as you notice I have highlighted in the pdf, left click advanced system settings.
Under advanced tab, we left click environment variables...
There are two boxes here.
We are concerned with system variables, however.
So we scroll down the list and highlight path and click edit.
Ignoring all the extra stuff in here, make sure you are at the end of the line, and type
Code:
;C:\android-sdk-windows\platform-tools
The semicolon allows us to separate it
from the previous path statement.
Click ok all the way out.
We now have ADB setup globally. We can use cmd.exe (I use powershell) and no matter what directory we are in, adb is recognized.
If it is not, make certain you entered the path into system variables, and made no typos.
If you installed to a different location, you will need to adjust the path accordingly.
This concludes the section on installing the Android SDK to use ADB.
This next section will be on using ADB, so please open that pdf now.
Now, this applies to any OS, not just Windows.
Well, with the exception of the USB drivers.
I will not go too much into that, but if you take a look at the PDF, it goes through installing usb drivers for the sdk, and how to download them.
Fiarly straightforward, in that rspect.
Now, to setup our phones to use with the SDK and ADB, we must change some settings.
First, we go to menu softkey, then settings.
We scroll down to Applications and tap it.
Under Development, we will check Enable USB Debugging. Please note the SGS phones are different in this respect.
The USB cable must be unplugged before enabling or disabling this setting.
Once this is done, we are now ready to play with adb
One quick note: If you get device not found/conencted, please reboot your phone. DJ05 has a quirk in it where ADBD randomly crashes on boot.
A reboot will fix this
ADBD= ADB Daemon
Ok, continuing on.
Lets look at installing applications. This is also known as sideloading.
Unlike installing from the SD card, it does not require unknown sources to be enabled.
The command for this is
Code:
adb install packagename
This assumes that you are working from the directory where the file is located.
This will install the application to /data/app.
It will also show sometimes useful errors if install fails.
That is not something you will see from the Android GUI.
Now, a lot of us have probably deleted files with apps like Root Explorer. While this isn't really a bad thing, it leaves behind databases and data for the application removed.
This is where the 0kb applicaiton entries come from.
If you take that application entry name, you can uninstall the extra data via adb.
First we go to the adb shell which logs into the phone.
Code:
adb shell
If we end up with a $, we will want admin rights, in many cases. This is not one of them, I don't beleive.
To get admin rights, you want to type
Code:
su
Look at your phone if this is the first time, it may prompt you to allow access. Else you will get permission denied.
If you are not rooted, this will not work either.
Ok, now that we are logged in, we will type
Code:
pm uninstall packagename
where packagename is the name of the 0kb listing.
Now this seems like a pain in the a** and I agree.
HOWEVER
There will be a time where Manage applications crashes when you try to uninstall it from the phone. In this case, a factory reset, or this method is the only effective way to fix the problem.
Moving on.
How many of us have removed system applications or renamed them? Did you know that you can simply disable them from the system?
Code:
adb shell
su
pm disable appllicationname
This will disable it, and the system will ignore it.
This can be seen as safer than deleting or renaming things, but your mileage may vary.
On the other hand, you can also re-enable these applications.
Code:
adb shell
su
pm enable applicationname
Please note: Not all applications will properly re-enable. I believe a factory reset or reinstall of said application will fix the issue.
Also, application names are absolutely case sensitive.
*nix based Operating Systems see the letter 'a' and 'A' as two different things.
when you log into adb shell, you are playing by android rules
Ok, a lot of us tweak and mod our phones and turning off the device to get to clockwork recovery, or battery pulls, or multiple button holds to get into Download mode are troublesome and annoying at best.
ADB can help us here.
Here, we do not need to be logged into the shell
If we want to merely reboot the phone:
Code:
adb reboot
If we want to go to recovery (works well with voodoo5)
Code:
adb reboot recovery
If we want to go to Download Mode because we need Odin, heaven forbid:
Code:
adb reboot download
Its instant. No waiting on animations or anything else.
Its also handy if Android has locked up, but yet still works in adb.
I for one hate taking my case off to battery pull.
So now we move on to pushing and pulling files.
Sometimes, I don't feel like mounting my sd card to copy a file over to my phone.
I can use this command to push a file straight to my sd card:
Code:
adb push filename /pathtodirectoryonphone
So for instance, if I have test.txt that I want to send, I would type:
Code:
adb push test.txt /sdcard/
and there it goes.
Ok moving on
Pushing files can be done to any directory, however, some are protected.
For instance, /system is going to give you a permission denied or a read only filesystem error.
To get around this, the easiest thing to do is push the file to your sdcard, then log into the shell:
Code:
adb shell
Code:
su
We will then mount the system as writable
Code:
mount -o rw,remount /dev/block/stl9 /system
Then we can use something like
Code:
cp /sdcard/test.txt /system/app/test.txt
cp stands for copy
and it requires the path of the file and destination path. The name of the file is optional
When you copy it, you can rename it to whatever you like.
For instance, if we wanted to backup a file
Code:
cp /sdcard/test.txt /sdcard/backuptest.txt
Now, lets assume you do not have busybox installed.
You non rooted users will not.
Then you must use a slightly more complicated command called dd
This is used like this:
Code:
dd if=/sdcard/test.txt of=/system/app/test.txt
if is for inputfile
of= output file
Not every user friendly, but probably one of the safer copy commands.
Ok, moving on to pulling files.
Lets say you want to get a file from your phone, to modify, backup, etc.
To do this, we simply use adb in this manner:
Code:
adb pull /pathtofile/filename destinationname
For instance, if I wanted to backup ADW launcher in system/app
I would do this
Code:
adb pull /system/app/ADWLaucnher.apk ADWLauncher.apk
And it will pull the file from the phone and put it in the current directory.
Like above, you can specifcy where it goes.
pushing files to the sdcard, it seems prudent to talk about changing permissions.
sdcards are typically fat32, which destroys permisisons, and Android is heavily permission based.
So if you push an application to your sd card, then try to copy it to /system/app/ bad things are going to happen, or the app may not even show up.
So in that case, we use something called chmod.
This is used in this manner
Code:
adb shell
su
chmod 755 /pathtoapplication/applicationname
Keep in mind
you dont want to do this while its still on your sd card.
an example
Code:
adb shell
su
chmod 755 /system/app/ADWLauncher.apk
755 is good for applications and script files.
Just a couple more topics to cover.
Lets go over deleting files.
This becomes especially handy for removing rogue applications.
To do this, we must be in the adb shell.
Code:
adb shell
su
rm /system/app/ADWLauncher.apk
You may need to remount system as writable with:
Code:
mount -o rw,remount /dev/block/stl9 /system
That applies when using chmod as well.
So what I did above was delete ADW Launcher from system/app
However, what if I wanted to delete the entire contents of a directory?
Same thing as before, except
Code:
adb shell
rm -f /data/dalvik-cache/*.*
I just cleared my dalvik-cache with that command
very quick, very effective.
If you just tried that, please reboot your phone now
Ok....this leaves us with the final topic: logcat
logcat allows us to log what the OS is doing, and possibly delve information for when things are not working
its quite simple Reading it is another.
To use logcat
Code:
adb shell
logcat
To logcat to a certain file do
Code:
adb shell
logcat > /sdcard/logcat.txt
Now we let the log settle down to a reasonable amount of data coming in and not a wall of scrolling, then start the app in question. When it gives an error, we hit ctrl-C and kill the adb shell session.
This should have captured enough data to see the error. Now, I prepared an example. A user came to me on IRC, and Google Maps was force closing. Clearing data didnt fix it, Clearing dalvik-cache, and fix permissions did not fix it. In this case, the user did not know how to use adb So I had him grab an app called alogcat from the market and email me the log. This is also a very valid method.
this file explains what the problem was, and highlights what to look for as an example.

This concludes the guide from Adrynalyne, there will be more workshops such as this one in irc.freenode.net #android-learning.
Thanks to everyone in #samsung-fascinate !
Reserved for possible extension of topic
Great, saves a lot of questions/answers & search
Every new user should read this!!
Thread stuck as valuable reference thread
Just to add, if I may, a little about the permissions...
============================================================
File permissions for Unix... which Android is based, just so those who tinker with the file permissions may know what they are getting into.
============================================================
Use the chmod command to set file permissions.
The chmod command uses a three-digit code as an argument.
The three digits of the chmod code set permissions for these groups in this order:
1.Owner (you)
2.Group (a group of other users that you set up)
3.World (anyone else browsing around on the file system)
Each digit of this code sets permissions for one of these groups as follows. Read is 4. Write is 2. Execute is 1.
The sums of these numbers give combinations of these permissions:
0 = no permissions whatsoever; this person cannot read, write, or execute the file
1 = execute only
2 = write only
3 = write and execute (1+2)
4 = read only
5 = read and execute (4+1)
6 = read and write (4+2)
7 = read and write and execute (4+2+1)
Chmod commands on file apple.txt (use wildcards to include more files)
Command Purpose
chmod 700 apple.txt Only you can read, write to, or execute apple.txt
chmod 777 apple.txt Everybody can read, write to, or execute apple.txt
chmod 744 apple.txt Only you can read, write to, or execute apple.txt Everybody can read apple.txt;
chmod 444 apple.txt You can only read apple.txt, as everyone else.
Detecting File Permissions
You can use the ls command with the -l option to show the file permissions set. For example, for apple.txt, I can do this:
$ ls -l apple.txt
-rwxr--r-- 1 december december 81 Feb 12 12:45 apple.txt
$
The sequence -rwxr--r-- tells the permissions set for the file apple.txt. The first - tells that apple.txt is a file. The next three letters, rwx, show that the owner has read, write, and execute permissions. Then the next three symbols, r--, show that the group permissions are read only. The final three symbols, r--, show that the world permissions are read only.

Thanks for the guide. Helped me pick out the stupid stupid mistakes I was making...so just a problem. I'm able to use fastboot easily but I seem to be unable to use ADB still on my windows 7. It says there are no devices and I'm dang well sure I have USB debugging on. Is it because Windows 7 is missing drivers for the nexus one or something else?
wonderful guide. I would like to add it to the guides thread.
Really awesome work, thumbs up.
But we should also take a guide on installing adb with Ubuntu/Linux, which isn't a very difficult thing...

This is good but I have a problem, when I try to remove an .apk file from /system/app it fails and says 'rm failed, Directory not empty'
I have followed exact instructions many time but never succeeded :s any help!!
(I am runnging these commands in device mod)
when I am in recovery mod I get this prompt ~ # and I am not able to enter su mod. how to get rid of this??
Well when the $ changes to # it means you have SU access

Ok i think you need to do a recursive force delete which should be rf but i am not too sure! could somebody please confirm/ correct this?
Well, I don't think so ^^ As he doesn't want to erase a whole directory, but only a file.
What surprises me the most is the returned message... You're trying to delete an apk, and it says it's a directory :/
Could you please give us the output of this :
Code:
su
mount -o rw,remount /dev/block/stl9 /system
ls -l /system/app/mytouch*
Perhaps you don't even need the su and mount lines, but I'm not sure about that, and that can't harm your system ^^

I know he doesn't want to delete a whole directory, but since the apk isn't compressed perhaps android looks at is as a directory and not a file? i don't know since what was returned suggested that it was a directory i presumed it was a directory! :S

How To Deodex Your Device Tutorial
What is odexing?
What is deodexing?
Why you may consider deodexing over odexing.
Disclaimer: This tutorial is meant as a guide for education purposes only. If you decide to take the initiative to perform a deodexing operation on your device a family member’s device or a friend’s device – you (the surgeon) assume all responsibility for you own actions. In other words… Your problems are your own… Read before dissecting!
What is Odexing? – Within the Android Operating System applications come in the form of .APK packages compiled with .odex files that work with the primary application. Odex files are compiled with portions of the main application manifests and hold partial instructions for how this application will boot, how it will run and how it will act within the entire file structure. These odex files hold instruction for an application to pre-boot, pre-launch and how the service (if any) will function. Some assumptions are that the speed of the file system and application will be increased by way of pre launching the application prior to usage. My thoughts on this are that battery usage and memory are also being consumed while you may not even draw on that particular application. Simply put, the Odex file holds a set of functioning instructions for the application it belongs with. Think of it as sort of a pre-buffer and caching at the same time.
What is Deodexing? – Deodexing is the process of removing the child instruction file from the parent file and importing all the information that has been removed from the odex file into the APK. Full freedom to perform on its own without the aid of little odex.
Why may you consider deodexing a file system over having an odexed file structure? – Application modifying can be near impossible with many instructions for a single application existing in various places of the file structure. Consolidating all the functions of an APK in a single location will help to simplify the process.
Are you ready to become deodexed…?
So, get your scalpel ready and let’s begin…
This process will be described working within a Windows environment.
You will need to have a few things in order before we begin:
1) A Rooted phone – (A Must)
2) A working Windows workstation or desktop
3) xUltimate Utility v2.2.1 (see the link from my prior post to download the tool)
http://forum.xda-developers.com/showpost.php?p=12024563&postcount=126
4) Developers SDK toolkit – or – the ability to run adb commands
5) A little time to burn
Let’s get started:
1) Assuming that you have already downloaded xUtility v2.2.1 – unzip the package to a directory you can easily access.
2) Make sure to put your device in debugging mode and plug the USB cable from the PC into your device.
3) You can run the Test.exe to verify that the xUtility sees your device, but it’s not necessary and may cause a doubling effect with adb so that your device won’t be seen – so just execute the Main.exe and wait for the device to communicate with the application.
4) Once your device has been read by the xUtility, answer the questions in the prompts according to your make and model. (You do not need to upgrade to a newer version of xUtility because this is the newer version – regardless of what the application states)
5) Execute Action 1 then follow the instruction at the prompts
6) Execute Action 2 then follow the instruction at the prompts
*Note: For any reason the process fails to begin or hangs during the process – verify that there is only one instance of adb running on your PC or this could result in issues.
*Note: If issues occur, you can always perform an adb pull to the origi_app directory (within xUtility) and then the origin_frame directory (within xUtility)
*Note: This could take some time depending on the size of the directories
7) When the migration is complete - perform Action 3 in xUtility - This will perform the deodexing of the application APKs.
8) When the Application Deodexing is complete - perform Action 4 in xUtility - This will perform the deodexing of the framework APKs. (Mainly Java Files)
9) For safety purposes – backup the files in both the origin_app and the origin_frame directories and put them in a safe place just in case.
10) Close the prompt for xUtility – the process should be complete.
11) Exit debugging mode with your device and enter into mass storage mode. You will need to remove the USB cable before performing this, then plug the USB cable back in once the mode shift has occurred.
11) You should now see your device in Windows as a mass storage drive.
12) Go into the xUtility directory and copy the 2 folders named – “done_app” and “done_frame” to the root of your internal SDCard.
13) Get your command prompt open and get ready to type some code
Just my preference - Prior to migration of the deodexed files I chose to wipe the dalvik-cache from my device to ensure no rouge variant cached instructions would be present after the next boot. – You could CWM into the next soft boot and perform a dalvik wipe if you choose.
At The Command Prompt: Code Below:
adb shell
# su
# stop
# mount -o rw,remount -t ext4 /dev/block/mmcblk1p21 /system
# cp /sdcard/done_app/* /system/app/
# cp /sdcard/done_frame/* /system/framework/
# rm /system/app/*.odex
# rm /system/framework/*.odex
# chmod 644 /system/app/*
# chown root.root /system/app/*
# chmod 644 /system/framework/*
# chown root.root /system/framework/*
# mount -o ro,remount -t ext4 /dev/block/mmcblk1p21 /system
# reboot
After your device reboots it will take longer than usual to load the new file settings – so be patient and don’t panic.
You now have a deodexed device!

If they knew enough to flash a custom ROM then they should know if the ROM that they flashed was deodexed or not if posted by the developer.
Then they wouldn't be on this thread reading this post unless they wanted a bit of an education on the topic.
Hence making your remark quite pointless!

agreed. so many people dont even bother to read the OP on a rom thread and ask if feature X exists, when its clearly labeled as such in the OP
not something I'd be willing to do regardless if my phone has a deodexed rom or not. seems a lot could go wrong if you made a slight mistake especially with running commands on your phone.
but at least I now know what deodexing is now

Yeah, I guess I was reaching on that statement... anticipating the best - but real world scenarios prevail!
What can I say... I prefer to be an eternal optimist.
But the statement was written to read "they should know" like as in if you lick the inside of a freezer door... "you should know" that it is highly likely that one would remain there until the thaw...minus a few layers of skin of course
Basically I got the idea to write this tutorial when reading a few threads whereas many users wanted to make some cosmetic mods to their devices, but really didn't want to jump out of their factory installed file systems. I noticed a few theme developers creating a skin pack for certain features, such as lock screens, docks, etc... and it required a deodexed file system. Many people didn't understand or even know what deodexed meant, let alone some never even heard of the word.
I posted in one of the threads that If I were feeling ambitious that I would create an educational tutorial and guidelines to perform the operation if one was interested... after getting injected with some knowledge.

I Agree with you on this.....WELL SAID! And Thank You for the time invested on a great tutorial/ lesson. I too learned a thing or two.
I would like to add four lines of code to the set of commands you type in adb shell
adb shell
# su
# stop
# mount -o rw,remount -t ext4 /dev/block/mmcblk1p21 /system
# cp /sdcard/done_app/* /system/app/
# cp /sdcard/done_frame/* /system/framework/
# rm /system/app/*.odex
# rm /system/framework/*.odex
# chmod 644 /system/app/*
# chown root.root /system/app/*
# chmod 644 /system/framework/*
# chown root.root /system/framework/*
# mount -o ro,remount -t ext4 /dev/block/mmcblk1p21 /system
# reboot
The reason for these additional commands is that when any files get moved to /sdcard, and directories under it, the ownership of the files becomes system.sdcard_rw and the permissions for the files become rwxrwxr-x. When these files are copied back to their original subdirectories under /system, they retain the new ownership and permissions. The original proper ownership and permission for the files before any changes were made was root.root and rw-r--r--. The four commands I added restores them to that original state, and therefore does not create any unintentional security risk. If anyone has already done the procedure. They can fix the files by doing just this in an adb shell.
adb shell
# su
# stop
# mount -o rw,remount -t ext4 /dev/block/mmcblk1p21 /system
# chmod 644 /system/app/*
# chown root.root /system/app/*
# chmod 644 /system/framework/*
# chown root.root /system/framework/*[/COLOR]
# mount -o ro,remount -t ext4 /dev/block/mmcblk1p21 /system
# reboot

Raj, thank you for providing the additional lines of code. Yes, you are absolutely correct. It was very late.... uhm very early in the AM when I was was proofreading and it didn't pop out at me then. Now, it pops.
The OP now reflects the additions and credit was given to you for the additions in the edit.
Thank you again my friend.

This is the tutorial that I'm looking for. I already ask many times how to deodex my captivate but nobody answer it until I find this thread. Two thumbs up.
ps: could you add a video tutorial? I think a video is more informative for me because I don't have any experience with adb so that I little bit confuse if there is a command line using adb.

The actual creation of an arm linux chroot image is probably out here on teh internetz somewhere, but I can assist with my mounting shell script (which works).
My image is of a debian arm chroot, and the image filesystem is ext2 (a good idea for fewer writes. ie innately non-journaling), has been used extensively on fw DE .17 and I'm currently trying it out on WW .29 (thank you, miloj).
I would upload my debian img somewhere, but I've actually broken it somewhat (it works for my needs, but it's nonetheless a bit too hacked up to be reliable).
I've modified it somewhat for generalization, some of it is probably wrong and/or redundant, and it IS hackish and ugly, but it works for me (tm).
* the chroot image only need a root account (and probably bash installed, but it usually is)
* You need busybox installed.
* You need to upload your chroot image named linux.img to the internal sdcard in a folder named linux
A shell script to set things up is attached.
What you need to do:
push the install script and run it:
Code:
adb push installlinuxstuff.sh /data/local/
adb shell sh /data/local/installlinuxstuff.sh
Now you can (from adb shell or terminal emulator on device):
Code:
su -
/data/local/mnt/linux.sh
/data/local/mnt/notlinux.sh
Feel free to remove the install script at
/data/local/installlinuxstuff.sh
when you've got it up and running.
Alternative way to run the scripts from adb shell:
Code:
adb shell su -c /data/local/mnt/linux.sh
adb shell su -c /data/local/mnt/notlinux.sh
I usually symlink start and stop (in my case deb and undeb) shell scripts placed in /data/local/mnt in /system/bin (ie shell scripts with 'su -c /data/local/mnt/whatever.sh' in them) for easy start an stop from terminal emulator, and if you've gotten this far you may welcome the small advice. (in other words - don't do this unless you _really_ know what you're doing)
Debian ARMHF or ARMEL?
If you would uploaded it (good place is google drive , sharing as public, as there are no ads or bull**** and the download is extremely fast) I would love to try your image - after modifying your script so it can work on a UHS-1 class MicroSD I want to try running this off of (should give it a little more speed).

Armel (I use the same chroot installation on my phone in a smaller image file (with less stuff installed)). I've got loads of personal stuff all over it and besides - it's somewhat broken. I really don't want to try to fix it.
So I'm working on retracing my steps, creating a clean armhf ext2 image (debian wheezy base installation for now) and redo the mount script, but I can't make any promises on a release date.
Anyhu - there are loads of images (armel, at least) on teh internetz (BT5 and too many ubuntu, for instance).
Just check so our kernel can mount the filesystem.
Edit: if not you can just create a new image file with a filsystem that's mountable and copy the chroot files to it.
So the ideal image for this tablet is armhf? If I wanted to create a Gentoo image, I would go with armv7? I'm just not sure exactly which ARM architecture this tablet is.

The CPU is the Tegra 3 if you want to google it and it is an ARMv7 w/ NEON extensions chip. ARMv7 specification requires hardware fp so naturally it is ARMhf.
Nice to hear, keep us updated on your progress. I'm currently running an armel copy of Ubuntu 12.04 but it has problems with some packages and others are armhf only.
When I run linux.sh, I get an error that /sdcard can't be mounted because it doesn't exist.
Code:
mount: mounting /sdcard on /data/local/mnt/linux/sdcard failed: No such file or directory
I also tried changing the script to mount /mnt/sdcard, but that didn't work either.

Yes, it is somewhat hackish, like I wrote. My image has got an sdcard folder (/sdcard) inside of it where I mount /sdcard from android. (Ie chroot and mkdir /sdcard)
followed this:
http://androlinux.com/android-ubuntu-development/how-to-install-ubuntu-on-rooted-transformer-prime/
make sure you have busybox installed der. Or at least the cp command in /system/bin
works well on my TF300T, Yea its not native but im currently configuring it for kernel building ;-D

Why does the mount script remount a non-existing block device with an ancient (according to android) filesystem?
Code:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
Edit: I read all the scripts, and they all mount that crap. It's not made for transformers, and on the android device it's made for it leaves /system mounted rw after you've run it, and WHEN run (installed) it modifies too much in /system/bin
Code:
# At first it copies loads of crap to /system/bin, and then:
cd /system/bin/
chmod 4777 *
It's not even "hackish" - it's just... wrong...
Will loop1 work every mount?
Code:
mknod /dev/loop1 b 7 0
losetup /dev/block/loop1
I'm almost only asking, since this thread was supposed to be about scripts?

Thanks. I created /sdcard, and it works almost perfectly now. However, mounting devpts at /dev/pts doesn't seem to work. I replaced that line with
Code:
mount --bind /dev $mnt/dev
and it seems to work fine. Is there anything wrong with my method?

I'm assuming you're talking about the link in the post you quoted, even though you seem to be referencing the OP's use of the word "hackish". The script in the OP doesn't do any of that stuff. It just creates a few directories in /data/local/mnt/ and writes the mount/unmount scripts, which themselves only un/mount appropriate directories for the tablet. As for your question, I'm not nearly experienced enough to answer it. Sorry.

AFAIK your mount seems to be more complete, ie more android hardware goodies accessable from the chroot environment. However - that means more things possibly going wrong (like writing to a device who's critical to the android environment).
Personally I'd try to find what "hardware goodies" and whatnot I'd need to get the chroot environment working optimally, and not mount ALL of /dev.

Yes, and the OP is very honest about his script(s) being "hackish", which I interpret to mean 'not optimal, possibly redundant but working', all of which it is (and I applaud the early release, since for instance I could get things rolling), but the ubuntu image installation and mounting scripts from the other poster ( whom I was addressing ) are plain faulty.
I am looking for a armhf build of ubuntu or debian that I can chroot (newer the better), if anyone knows of such a build that would be fantastic but if not does anyone know of an easy to follow guide to compile such a thing?
I found two pretty good guides. I mostly followed THIS ONE, but I found that it doesn't mount enough before "first boot", so what I did was follow the guide until the point where you move the image to the tablet. Then I ran the OP's installlinux.sh script, and then the mount script. However, the mount/unmount scripts need to be edited before using them. Comment out the sdcard line and probably the devpts line (mounting devpts didn't work; Bash complained that devpts didn't exist; I had to replace it with the line I mentioned a few posts above, but as /dev/void says, it could be problematic, so be careful). Mount the image, make the /sdcard directory, exit, unmount, and edit the scripts again to mount/unmount /sdcard.
Next time you enter the chroot, feel free to run the
Code:
sh /debootstrap/debootstrap --second-stage
command to build the image, and follow the linked guide until the next time it tells you to exit the session (NOTE: The second echo "whatever" > sources.list command is wrong; it should be echo "whatever" >> sources.list; Also, remember to replace "squeeze" with the appropriate Debian version, in my case, "testing"). Instead of exiting right after the apt-get update, I'd recommend playing around with the chroot and configuring whatever apps you install. You can just use the OP's scripts now and ignore the script in the linked guide.
When the guide I linked above gets to this line:
Code:
sudo debootstrap --verbose --arch armel --foreign squeeze /mnt/squeeze/ http://ftp.debian.org/debian
just replace armel with armhf, and if you want a testing image, replace squeeze with testing.
Sorry I'm not attaching my image. I made it gigantic (5GB), so I don't really have anywhere to store it, and you probably wouldn't want to download a file that big. Plus, it already has Openbox and a bunch of other things you probably don't want installed. I'm assuming you'd want GNOME or KDE instead.
I can't figure out how to delete some of the system apks off my rooted Nook Simpletouch. Running 1.2.1, and Nootered it. Tried to ADB uninistall Phone.apk, but it just reports failure. I could use some help.
/system is usually read-only.
To make changes in its content you need to remount it read/write:
Code:
stop
mount -o rw,remount /dev/block/mmcblk0p5 /system
The stop is to be on the safe side, it stops the android subsystem.
After you are done making changes it's best to:
Code:
reboot

Just rename them. add ",bak:" to the end or similar. This will disable them, and if you notice instabilities because of getting rid of them you can just remove the appended extension. If everything runs well, you can then delete them with no worries.
I've renamed some of the recommended ones and have an error that comes up. "A problem has occurred, contact support". I need to figure out what is causing that to happen. its annoying but doesn't seem to be an actual problem.
What does "mmcblk0p5" represent?
mmcblk = multimedia card block device, 0 = first device, p5 = fifth partition
Thanks Renate, but It's not working. In order to rename or delete an apk off my Nook simpletouch, would someone please give me step instructions? I feel I'm missing something.
Code:
stop
mount -o rw,remount /dev/block/mmcblk0p5 /system
cd /system/app
mv BoringApp.apk BoringApp.bak
mv TediousApp.apk TediousApp.bak
reboot
And don't tell me that you have no boring or tedious apps!
The advice here is correct, better to rename sysapp extensions (.bak or .ap_) than delete as some might be needed by future apps/sys hacks/kernels. For those who can't adb by cable or keep it up wifi-wise, this is the easiest way even easier than root explorer:
https://play.google.com/store/apps/details?id=com.ghisler.android.TotalCommander
for sys or user app removal if you have to and can't use adb or even total commander, but then you shouldn't if not knowing sys file structures (I use Pro version, for removing many apps i just tested in a batch, sorted reminder):
https://play.google.com/store/apps/details?id=com.jumobile.manager.systemapp
I renamed talk telephone music audio etc apks on nst but Gallery is the only one I removed on all android devices & nst as it's just nasty which has never been missed by later hacks and quickpic is much better anyway:
https://play.google.com/store/apps/details?id=com.alensw.PicFolder
I created another directory under /system called archive. I move apps I don't what to use and fonts I change into /system/archive then I can just move them back if I have issues.
This still isn't working. My commands keep getting rejected. It isnt allowing stop to work. Also, I tried "adb cd /system/apps" and when that didn't work, I tried
"adb shell"
"#cd /system/apps"
No dice.
EDIT: Got it. needed to call it shell instead of adb. I also accidentally wrote "apps" instead of "app".
