The focus of this thread is to sort out the Apps2SD issue in cyanogenmod-darch 2.1 ROM (like the title says). Please do not post here unless it relates to this issue.
That being said, here is where I was at in the original darchstar 2.1 thread:
watzone69 said:
Taken from the instructions darchstar gave in the first post of his thread...
Code:
adb remount
adb push e2fsck /system/bin
adb shell
cd /system/bin
chmod a+x e2fsck
a2sd
reboot
First, the "chmod a+x e2fsck" command doesn't work for me (EDIT: I discovered that it WILL work in recovery mode). I had to use "chmod 777 e2fsck". After entering "a2sd" it gets enabled. After rebooting, apps2SD is NOT enabled anymore. I realized this by doing this test:
Code:
adb shell
cd /data/app
pwd
If your apps2sd is enabled, you will get "/system/sd/app" returned to you.
If you get "/data/app" returned instead then apps2sd is NOT enabled!

After you restart, can you re-enable a2sd by running a2sd from a terminal as root?
If so, do all your apps still appear and are they usable?
If the above is true, try adding this to the end of gumbo.sh
Code:
su -C a2sd
for a quick fix.
Start a thread (to keep things less cluttered) about it and I'll help you guys dig into the boot image and see why it's not sticking.

So, I rebooted and tried to run "a2sd" from the android terminal but it spits out a long string of errors:
Code:

+++ Apps-to-SD successfully enabled
So, there is no "app" or "app-private" in the "system/sd". Is a2sd supposed to generate those directories or are they supposed to be there before hand?
Anyway, the result is that I lose all of my shortcuts to the apps and market shows them as not installed even though they are.
BTW, I am not a dev or even that great at code or linux but I can usually pick stuff up fairly quickly. Just want to help fix this!
EDIT: The only thing I have found to work is to flash this kernel:
http://forum.xda-developers.com/showpost.php?p=5712377&postcount=1406
However, some people get stuck in a boot loop after flashing this.
Running into the same issues as Watzone so I can confirm that he is doing it correctly. =P
Here are all of the related commands that have been suggested whenever the question of apps2sd has come up in the darchstar 2.1 thread.
Code:
adb remount
adb shell
mkdir /system/sd
Code:
adb remount
adb shell
busybox --install /system/xbin
a2sd
Code:
cd C:\android-sdk-windows\tools
adb remount
adb shell
chown system.system /data/app
chmod 0771 /data/app
For the next command, boot into recovery and do the following:
Code:
adb shell
mount /system
exit
adb push e2fsck /system/bin
adb shell
cd /system/bin
chmod 777 e2fsck
Now, boot normally and go back to your CMD prompt...
Code:
adb remount
adb shell
a2sd
EDIT: In other threads I have seen the command...
Code:
apps2sd on
...used to enable apps2sd.
Doing all of these WILL allow the final "a2sd" command to enable (testing with the "pwd" command) but it all goes KAPUT after a reboot.
why it's not being enabled at boot time is because the init.rc isn't calling /system/etc/init.d/04apps2sd . I'll be sure that we fix that in my next release
And there you go.
It works here, but now I know why. I'm still using an old version of the boot image that looks for /system/bin/a2sd to load it, and an older version of the ROM. No sense in me to keep flashing fixes until I'm done tweaking the kernel. When darch says the kernel is good, then I'll catch up lol.
We might as well use this thread to learn to play with the boot image though, that is if you guys want to.
Awesome can't wait for the next release then! Lotsa apps out there calling out to me! Thanks guys =)

You bet. It's about time I got my hands dirty.
I'm game let me know if you need me to test anything!
Cool deal. You need Linux to extract and compress the boot.img, and you need to be current with Perl and running jre5 or higher.
Ubuntu 9.04+ is set up out of the box, but any version can be made to work.
Then grab these files from Lox -

http://forum.xda-developers.com/attachment.php?attachmentid=234040&d=1254622769
and extract them into your sdk/tools dir. (or any dir in your path)
get all that, then pick a boot.img from a rom and put it in a work folder.
Holler when you get that far, or if you have any q's.
I wanna learn myself. This should apply to mac os as well?
I have Mint on another machine. Gimme a bit to get caught up...

np. I'm @work so going slow is better anyway lol.
ok i just ran the files in terminal. so i guess it might work.
I'm back
Inisde the work folder you dropped the boot.img into, run this from a term:
extract-kernel.pl boot.img
extract-ramdisk.pl boot.img
it will give you several files and a new directory. That dir is the unpacked ramdisk. The init.rc file is the one we're looking for. Open it with a Unicode editor and read it. It has it's own syntax, but it's almost like bash and not too hard to figure out. Hopefully you loaded a bootimg that has a2sd in it. Look near the bottom of the file for the a2sd start up line. It will have a2sd, apps2sd, a2sd004 or something like that. Once you find it so you can see the name used, search the rest of the file for that name.
Those lines will show you how a service gets declared and called at boot time.
I'm up and running now. I downloaded python 2.6.4. Do I need to install it or just extract it somewhere? Please forgive my linux noobness.
The other 2 zip files are extracted and in my tools folder. I'm getting the boot.img now.
idk if this will work as i too am a newb to android and the way they deal with the boot process is somewhat a bit different from what i'm used to, but heres a new boot.img if you guys want to flash it to see if apps2sd works. note, this is not a zip, remove that suffix.
to flash it to your phone just move the boot image to your sdcard then reboot into recovery. from there go into adb and mount your sdcard, then flash the new boot image.
Code:
adb shell
mount /sdcard
flash_image boot /sdcard/newBoot2.img
reboot
tell me if it fixes your apps2sd problem or not.

you gotta make it executable
inside the directory with the perl scripts do this
Code:
chmod a+x ./
My Xoom is rooted and running tiamat 1.41.
I'm trying to push a file onto the xoom and having trouble with it.
I have the Android SDK installed.
When I type ADB DEVICES, it shows my xoom listed as a long string of letters and numbers.
I figured out I could get into the shell by using ADB -s ###### shell (where #### is the numbers/letters shown as the device).
If I type remount, i get permission denied.
If I try to push a file onto the Xoom, I get permission denied.
What am I missing here and how do I mount the Xoom so that I can push files onto the it?
Anyone know where the libflashplayer.so goes? I have the official flash installed and don't see it in /system/lib
you have to cd into the directory where adb is. most people put it right on the root of there C drive so in terminal type "cd c:\android-sdk-windows\platform-tools" without quotes then type "adb remount" and you should be mounted
if you need more help with adb check out this guide http://androidsamurai.com/forum/viewtopic.php?f=12&t=4&sid=b8c229b771793d03bb84efbcf562e55b
I have tools and platform-tools directories in my PATH so I can run them from any directory. Even running it from the directory containing the executable fails with 'remount failed - operation not permitted'
you could try uninstalling and reinstalling android sdk

You're not in insecure mode. I thought flashing that kernel would put you into insecure mode? Maybe you need to reflash?
If you still actually have a working su binary, copy the file somewhere writeable, then su to root, then copy it from there again to the location.
Hey Guys,
can someone help me ? I will raun the Data Recovery Program of Testdisk and Photorec on my Transformer HC3.2 as SuperUser in a Terminal Emulator for Android. The Terminal Emulator runs great. At same time a tested it with an SSHD.
I have Downloaded the Linux Version of Testdisk (Linux, kernel 2.6.x i386/x86_64)
If i will start the file "testdisk_static" solo and with su command but every time it says "permission denied". In File Explorer i set the PErmissions of the file and in the command shell two times with chmod 7777 but se thame problem.
Permisson Denied !!!
Has someone any idea how i can fix this problem ???
Here is the Link of the Programm : cgsecurity.org/wiki/TestDisk_Download
I think testdisk and photorec are not include in Busybox. As far as I know, you just can't run them directly on Android.
Problem:
I've worked with every available distribution of Linux, trying to get the damn thing working on my phone. Troubleshooting the ***t out of it, and no deal. Constant errors/files not found etc. So, rather than post my logs and ask for help troubleshooting them (as I've obviously been unable to do), I thought I'd just ask:
Does anybody have a Linux build (besides android!) working on their phone that's running Gingerbread or ICS? If yes, can you post your software specs?
Here are mine currently:
Busybox- v1.19.3-Stericson in /system/xbin
Firmware Version- 2.3.5
Baseband Version- T959VUVKG6
Kernel- 2.6.35.7-T959VUVKI3-CL611444
Build Number- Gingerbread.VUVKI3
Mod Version- Octaine Team Acid
Thanks, this has been a pain in my **s for too long now!

I had both Fedora and Ubuntu working on Froyo at one point through lots of modifying and editing of the scripts.
What do you need them for anyway? I think it's more of a hassle to set them up than it's worth.
Well, I am working quite a bit now with linux for servers and such, and it's good to have a system (even minimal) that I can use/reference, plus it helps me get better at it.
Get this: I was so frustrated that I went back to BlackIce (keeping my gb bootloaders) and the damn thing loads right up, ubuntu 11.04, no problem. So, I then loaded up Valhalla's GB build and, sure enough, that works too. So, going with my luck I load octane 2.x GB which i've been digging of late and no deal, ubuntu just won't load.
Now, trying the same trick I cannot get it to work. It just won't load now when I SH it. Here's the instructions that worked before (and I've tried them all!):
http://www.nerd65536.com/2011/07/installing-ubuntu-in-android-version-2.html
Also, I hard bricked again (corrupted bootloaders from a Parallels Windows stallout) but did Adam's UnBrickable Mod and that's all better. Everybody needs to check it out, it's awesome:
http://forum.xda-developers.com/showthread.php?t=1333424
So FBI, any idea why linux is so temperamental? Once it SH's properly, it always works.
(Thanks to all the developers for their great roms!)
Yeah I noticed that slight changes from different ROMs based on the same kernel base had that effect too. I'm thinking it had to do something with the busybox installations since I had to edit the script sometimes. For some reason on some installs running mount won't work unless you use it as busybox mount. It was very iffy like that. I haven't even tried it again because of how frustrating it is to get even a boot. The other thing is that if you try to do a shutdown from ubutu/fedora it doesn't even kill the processes all the way so the only way you can clear some ram up with with a reboot.
Yeah man, I was figuring Busybox myself. I've tried old installs, new installs, xbin only, bin only, xbin & bin, etc. It's so frustrating because I can't figure it out. When it was working it was great, pretty stable.
So the first problem always lists as:
Remounting /system rw...
Mount: no such file or directory
Usage: mount [-r] [-w] etc, etc
So does this tell us that the system is not mounted rw? I used the Mount/system r/w application, but I cannot verify it's doing it's job. Everything is rooted properly, CWM also.
In Terminal on the phone I ran:
"mount | grep system"
which gave me
"/dev/block/st19 on /system type ext4 (rw,relatime,barrier=0,data=writeback)"
which leads me to believe the system is r/w.
I'm converting the system back from ext4 using CWM Voodoo to disable Lagfix and system Lagfix to see if this has any effect. Will report.
No deal. Didn't do a damn thing. I'm going to crack this if it's the last thing I do....
I'm using Better Terminal Pro, Bash shell, and under command line in options it lists the Shell as: /system/bin/sh-
The sh install.sh also tells me:
"Mounting: Loopback mount
mknod: /dev/block/loop254: File exists"
Does this mean that all (255) of my loops are used? Do I need to remove programs?
The available loop device thing never got resolved. Nameless originally fixed it by making it use 254 so that there was a low chance of the loop device being available, but the phone's OS is very iffy about letting a new loop device get assigned to a system image file. Can't really help you out since I never got it to consistently mount with different roms.
Linux on SGS4G Working! Done and Done!
Figured it out.
I can get Ubuntu 11.04, 11.10 & Debian 6 to mount repeatedly in all sorts of ui updatable configurations using this information:
http://www.nerd65536.com/2011/07/installing-ubuntu-in-android-version-2.html
It's a friggin Christmas Miracle! Can't tell you how much time I've wasted working this out, and it all boils down to the sh and run scripts.
So, without further ado, here goes.
!!Make sure you're rooted!!
!!The quotes just tell you what to type. Don't type them!!
1.
Download one of the three builds on the website listed above (or build your own, it should work fine). Extract it from tar.bz2, they should all extract to a linux file, this includes the necessary scripts. Put it on the sd-card on your phone.
2.
Download the new scripts that (Nerd) listed found here: http://ohm.nerd65536.com/android-linux/scripts-latest.tar.bz2
And extract them. You'll have another file that says linux. Open it, take the three files inside (install.sh, root-scripts & scripts) and paste them in the linux folder you moved to your sd-card. They will overwrite the ones currently there. These scripts work for sgs4g, the originals did not.
3.
Install the latest BusyBox in xbin if it's not already installed (must be rooted). Latest is 1.19.3
4.
Download a terminal client, like Better Terminal Emulator or Android Terminal Emulator. I use the first. The terminal needs to run the commands as root, especially the linux vnc command as it didn't want to work for me no matter if I started by typing su. Better Terminal Emulator has a check box to always start in root.
5.
Open up your terminal emulator and type su if you are not rooted there. Then change directory to the linux file on the sd-card. run the sh file there.
Like this:
"su"
"cd /sdcard/linux"
"sh install.sh"
If it works, the resulting dialog in terminal won't throw up any problems.
6.
Get back to / on sd by typing in terminal:
"cd /"
You should then have a: / # prompt, which means you are still rooted.
Enter:
"linux"
Which should result in a: [email protected]:/#
This means Linux is running. Congratulations. It should continue to run unless you shut down your phone.
7.
Download a VNC client, like Android VNC Viewer (free) or Remote VNC Pro, which I use. Add a new entry in it, with the following settings:
Host: localhost
Port: 5901
Password: cheesecake
Color: 24-bit
Name: Linux
When that's done save if you can or back out if you can't, and go back to your terminal emulator.
8.
It should still say: [email protected]:/#
If it doesn't, fine, if it does, just go back to root prompt by typing:
"exit"
Which should get you: / #. Then type:
"linux vnc"
Which should run itself and mount the chroot environment. It should tell you your new 'X' desktop is localhost:1, and have a: / # prompt again.
It might also ask you for a password, if so then put whatever password you'll remember in that's longer than 6 characters and verify it. This only happens once.
9.
Go back to your VNC client and if you entered a password in step 8. then edit your listing to your password instead of cheesecake, if not then don't.
Click on the Linux link and BAM! (shameless Emerilism), you're at your Linux desktop which should be running a iceWM desktop interface, which is fast. The LXDE desktop is nicer and if you want that then go into you're terminal and get into the linux shell by typing:
"linux"
And then switch to LXDE by typing:
"apt-get autoremove icewm- lxde+"
Which will run through the removal/ installation, and verify you want to download the <400mb files. Type:
"y"
And give it time to finish. When finished, just go back to your VNC client and hit Linux again, and you will have a nice looking functional desktop, with a cpu load graph on the bottom. I tried using Gnome desktop and Unity 2d, but both of these would install and not fully run with all options. They are heavier and slower, but cool non-the-less. Let me know if anyone has luck with these on Android.
Notes-
You only have to type "linux vnc" once in terminal to start linux every time you boot your phone. Otherwise, just open your VNC client and click on Linux to use it. Easy!
You will want to update and upgrade your linux after install, do so by typing in terminal:
"apt-get update"
"apt-get upgrade"
Also, you might run across a problem if you try to add-apt-repository, that's because that python command is not present. To use it, enable by typing:
"apt-get install python-software-properties"
Also of note, the downloadable linux builds are sized to about 2.15gig on your sd, which is big enough for most. There is a way to resize them which I tried but it gave me trouble in loading. I will try again and see if I can get it to work.
Here's the link from Dangermouse:

You're welcome.
It's actually a lot easier than that to make the image larger. Just pop the SD card into a Linux machine and:
(Assuming the original file is: /media/phone/linux/linux.img)
Code:
resize2fs /media/phone/linux/linux.img 4095M
And you're done. resize2fs is made of magic!
Note: Most SD cards are FAT32, which has a filesize limit of 4GiB. The above instructions will make the file a megabyte less than that.
nerd65536:
Thanks! Worked like a charm. Had to e2fsck -f /media/SDCARD/linux/linux.img (phone plugged in to Mint) before i did it to check over the file system, but then it ran immediately. Much appreciated.
Have you had any luck on native boot? I've been working a little on this, as I can't run BackTrack arm well virtually, it gets buggy. Granted the telephony systems won't work during, but the functionality should be pretty good if we could run it standard.
Also, while I'm thinking of it, is it possible to run the img from an ext4 partition on the card? I have an existing one being used for link2sd files and would much prefer using it as it's a far superior file system to fat32, without the 4G limits. Vnc should have no problem graphically, but would the linux.img chroot properly?
It would probably work but you would have to alter the script to mount the other partition if it doesn't do it automatically and change the path. Shouldn't be too hard.

Hi! I'm new to android and I'm trying to install the command "file". file is a unix command that is used to determine the filetype of a file. I use this command a lot on my computer and would really like to have it on my phone as well. I downloaded the source but when I run ./configure I get permission denied even if I run as root and chmod 777. What am I doing wrong? Is there a precompiled version?
