How to run applications off the sdcard (Updated 6/3/09)

DOES NOT WORK ON CUPCAKE 1.5. Try one of the other apps to sd card threads.
I decided to create a new thread for hacking a rooted g1 to allow applications to run from the sdcard. The original thread's instructions don't work without some modifications and the original poster doesn't seem to have the time to update it.
I'll try to keep the original post as up to date as possible as new information comes.
Prerequisites:
1. Rooted g1 with jesus freak version 1.30 or 1.31, 1.41 (rc30, rc33) Works with all rooted US, UK, international versions of the g1.
2. Have "adb" from the android sdk installed on your desktop machine.
Sdcard preparation:
Divide your sdcard into 2 partitions. The first partition should be FAT, the second partition should be EXT2. This can be most easily accomplished using a linux or mac machine. For windows, you can use "paragon partition manager 9" to do this. It will allow you to partition your sdcard and format the 2nd partition to ext2 fs. It is very important that the 2nd partition be formatted as EXT2 or the rest of the procedure will NOT work. The 2nd ext2 partition will be used to store your installed apps.
In the original thread, somebody mentioned a HP sdcard partition tool program, but I don't believe that will allow you to format the partition to EXT2 fs.
Procedure:
1. With the phone off, insert your newly partitioned sdcard into the g1.
2. Connect your g1 to your desktop via the usb cable and turn it on.
3. Backup your original mountd.conf and initrc.rc files from your g1 by running the following commands on your desktop from the cmd shell:
adb pull /system/etc/mountd.conf <dir on your desktop>
adb pull /system/init.rc <dir on your desktop>
4. Mount your g1's /system directory as writable via the desktop cmd shell:
adb remount
5. IMPORTANT! Create a /system/sd directory on your g1 via the desktop cmd shell:
adb shell mkdir /system/sd
adb shell ls /system and make sure that the directory has been created.
6. Download the attached modified mountd.conf and init.rc files to your PC.
7. Push the modified mountd.conf to your g1 via the desktop cmd shell:
adb push /<dir on your desktop of modified file>/mountd.conf /system/etc/mountd.conf
8. Push the modified init.rc to your g1 via the desktop cmd shell:
adb push /<dir on your desktop of modified file>/init.rc /system/init.rc
9. Reboot your g1
10. Connect to the g1 shell via the desktop cmd shell:
adb remount
adb shell
11. Check to see that the ext2 partition has been created and mounted:
busybox df -h
You should see a line that looks similar to this:
/dev/mmcblk0p2 1.2G 9.1M 1.1G 1% /system/sd
If you don't see this line, you didn't partition your sdcard correctly. STOP! Go back and do that.
12. From the G1 shell run the following cmds to copy your app and app-private directories from the internal g1 storage to the sdcard.
busybox cp -a /data/app /system/sd
rm -r /data/app
ln -s /system/sd/app /data/app
busybox cp -a /data/app-private /system/sd/app-private
rm -r /data/app-private
ln -s /system/sd/app-private /data/app-private
13. Reboot, enjoy all the extra storage!

Instructions without adb using terminal app by LucidREM
this is a form of the instructions from this thread .. but modified slightly to be used directly from the "Terminal" .. i did not use my USB on my phone to root or run apps .. everything i did was on the G1
$su
#mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
#mkdir /system/sd
6. Download the attached modified mountd.conf and init.rc files to your SD.
#busybox cp -a /sdcard/mountd.conf /system/etc/mountd.conf
#busybox cp -a /sdcard/init.rc /system/init.rc
9. Reboot your g1
$su
#mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
#busybox df -h
You should see a line that looks similar to this:
/dev/mmcblk0p2 1.2G 9.1M 1.1G 1% /system/sd
If you don't see this line, you didn't partition your sdcard correctly. STOP! Go back and do that.
12. From the G1 shell run the following cmds to copy your app and app-private directories from the internal g1 storage to the sdcard.
#busybox cp -a /data/app /system/sd
#rm -r /data/app
#ln -s /system/sd/app /data/app
#busybox cp -a /data/app-private /system/sd
#rm -r /data/app-private
#ln -s /system/sd/app-private /data/app-private
Reboot your g1
Update 1/19/2009:
Installing non-wipe custom themes shouldn't cause any issues. I just installed the BUUF theme and I didn't have to re-do the procedure.
Update 1/20/2009:
Added undo procedure by heldc
Update 1/27/2009:
Added procedure for moving data directory to the sdcard, without performance issues.
This is not stable so I've moved it to the bottom.
13. Copy /data/data directory from internal storage to sdcard. This is OPTIONAL as some people are still reporting issues.
mkdir /system/sd/data
cp -rp /data/data /system/sd
rm -r /data/data
ln -s /system/sd/data /data/data
Reversal procedure:
rm /data/data
cp -rp /system/sd/data /data
Update 2/7/2009:
Add instructions by lucidrem that doesn't require adb. Allows you to apply the hack from the g1 using terminal app

going to try this right now..i will tell you if it works on my G1

i followed all the steps and i was able to boot into my phone without any problems. I was also able to install apps from market BUT when i instaled them my STORAGE LEFT went down from 54 to 51MB.
**I can see all the apps i installed in /system/sd/apps
please help,
thanks

Running apps off the SD card show any signs off slowness or laggyness?

Hey I would like to know what software are u using to create the partition on the sd, I tried partition magic 8 and partition mananger but the softwares can't see the sd card.

I use Paragon Partition Manager 9

Only the apk files are moved to the sdcard. The apps database files are still on the internal storage and all the cache files are still on the internal storage. Its still a good idea to manually move them over to the sdcard.
So as you install more apps, the internal storage will still shrink, but not as much as before and will go down slowly.
You can try to also move the /data/data directory over to the sdcard, that will move all the database files from the internal storage to the sdcard, but I haven't tried that. If you have a class 6 sdcard, try it and see if that slows things down.

Now I have to figure out how to do the partition in Ubuntu Lol

hi,
i'm a total noob to this. I've managed to pull the mountd and init files to back them up. When I get to step 5: adb mkdir /system/sd when I press enter the cmd shell gives me the adb menu. How can I tell if the dir was created?
Thanks for any help you guys can give.

1) adb shell
2) mkdir /system/sd

thanks a lot.

For the person that asked how to partition your sd card in Ubuntu you can use partition editor under system-administration- partition editor

Thanks for the info but I just find out tha paragon partition mananger can creat ext2 partitions too
everything went right with the software it create my fat32 partition and the ext/2. what I don't know is if the ext/2 is formated and my computer with linux does not see sd card at all so right now I don't now how to confirm this.
ps. I try to look for the option SYSTEM THEN ADMITNISTRATION and it does not have the partition editor installed.

Try this and see if it works... I haven't tried it myself as I only have the stock sdcard and I know its going to be too slow.
adb shell
cp -a /data/data /system/sd
rm -r /data/data
ln -s /system/sd/data /data/data
reboot
If this doesn't work or its too slow, to reverse it do the following:
adb shell
busybox cp -a /system/sd/data /data/data
If this works well, I'll modify the original post...

ok.. strange that your internal storage is still at 52mb though.. something else must be eating it...
do this:

please help me move my apps to sd card

i know theres a thread but i'm confuse about what to install and run to transfer my apps to my sd card.
my sd card is already partitioned to 6gb fat32 and 2gb ext2 and its rooted with jf1.41 as well.
please give me a specific instructions cuz im a noob when it comes to adb shell sdk cmd or whatever computer words.
thanks in advance!

Well i'm a noob as well can't seam to finish the last step myself but i'll try my best.
Just a wild gues u r running Windows right?

yeah im using windows xp but it has vista transformation pack if that will make a difference.

Ok.
Have u got "modified mountd & init.zip (685 Bytes, 475 views)" wich is an attachement at the bottom of http://forum.xda-developers.com/showthread.php?t=468959 ???
Download this small zip from http://modmygphone.com/wiki/index.php/Setting_up_ADB . Unzip the files to a desktop and copy it to system folder after that follow this link http://www.computerhope.com/issues/ch000549.htm.
let me know when u r done???
But remember i am also a big time noob but just trying to help as much as i can when no one else will so if i get some thing wrong don't get angry with me just let me know what i told u that was wrong and that way we can help each other out and correct one n other.

if you copy the modified mount.conf and init.rc files to the SD card at the root then this would be the way in "Terminal":
$su
#busybox cp -a /sdcard/mount.conf /system/etc/mount.conf
#busybox cp -a /sdcard/init.rc /system/init.rc
#mkdir /system/sd
now that the modified files are there you MUST reboot .. this is all done after you have root and after you have done the double partitions on your SD card .. once you reboot you should go back to the "Terminal" to make sure everything's good
$su
#busybox df -h
if you don't see a line like this:
/dev/mmcblk0p2 1.5G 94.4M 1.3G 7% /system/sd
then something didn't mount properly .. so if you DO see this line now you can continue:
#busybox cp -a /data/app /system/sd
#rm -r /data/app
#ln -s /system/sd/app /data/app
#busybox cp -a /data/app-private /system/sd
#rm -r /data/app-private
#ln -s /system/sd/app-private /data/app-private
now the apps are all on the EXT2 partition of the MicroSD .. happy downloading

I don't know what i have done wrong but eveything i try i keep getting errors and u have been more then help full but i am proberly to stupid to do it my self and i know i can do it if only i could find a video toturial from youtube or so but can't find any so i am stuck here.
But thank you very much for all ur help i would never have gotten to the last step with out ur help.
So now my only option is a help video or remote pc help if that is possible.
Ps. xda should make u a Moderator or Admin cause u r very help full and u know what u r talking about.

it's a nice thought .. not really sure i'd want to hold that kind of responsibility tho .. i think it'd be like calling me "Mr. President" when i drive the local garbage truck .. these guys are doing great here .. i'm just glad to lend a hand and hope it helps out

Hey guys just thought i'd chime in.
Firstly just to clarify are you using adb from your windows system or are you trying to do this all on the terminal app because these commands are issued to terminal after replacing both mount.conf and init.rc as described above
$su
#busybox df -h
as above you should see a line "/dev/SOMETHING" "size data" "/system/sd"
if you don't see this line then there's most likely a problem with your card format, did you make sure you had fat32 first then ext2 in that order on the card, fat32 must be first. i find it helps to check if camera can use the sdcard, if it can't, reformat, unmount and check camera again.
Assuming you've gotten this right so far
#busybox cp -a /data/app /system/sd
#rm -r /data/app
#ln -s /system/sd/app /data/app
#busybox cp -a /data/app-private /system/sd
#rm -r /data/app-private
#ln -s /system/sd/app-private /data/app-private
and hopefully your apps should all work, but not appear as downloaded in the market (don't worry this'll change if you reinstall them from the market)
if you're using adb from windows to try the above the commands will be slightly different:
Procedure:
***********************************************************
- this can be skipped if you've already replaced the mountd.conf and init.rc
adb remount
adb shell mkdir /system/sd
adb shell ls /system
adb push LOCATION OF FILE/mountd.conf system/etc/mountd.conf
adb push LOCATION OF FILE/init.rc system/init.rc
(LOCATION OF FILE = the folder you have the modified files)
adb shell
reboot
***********************************************************
If you've skipped ahead
adb remount
adb shell
busybox df -h
as above you should see a line "/dev/SOMETHING" "size data" "/system/sd"
Again if this line doesn't exist you've missed something, go back
busybox cp -a /data/app/ /system/sd
rm -r /data/app/
ln -s /system/sd/app /data/app
busybox cp -a /data/app-private /system/sd/app-private
rm -r /data/app-private
ln -s /system/sd/app-private /data/app-private
reboot
and hopefully your apps will all work and again, not appear in market.
If this doesn't help please advise what error messages you are getting and exactly where everythings going wrong, maybe we can get you back on track.

just reformated the card from fat 16 to fat 32 as u said hope it works now lol.
And thanks for the help.
Keep u posted.

why does it say "No space left on device"???

untd.conf': No space left on device

Ok might be fine but better safe than sorry your last line says:
/dev/block/mmcblk0p1 1.3G 4.0K 1.3G 0% /sdcard
That means that you're sdcard in fat32 format is only 1.3gbs in size is that correct? I assume this means you're using the sdcard that came free with the phone (2gb) if your card is larger say an 4 or an 8 something has gone wrong, but if this is correct lets move on.
cool so your sdcard is now partitioned fat32 -1.3gb followed by 0.7gb ext2
better safe than sorry redownload http://forum.xda-developers.com/attachment.php?attachmentid=139735&d=1230107855 the files and place them (the 2 files, not the folder) in the same folder as adb (do not mount your usb card)
>adb remount
>adb push mountd.conf system/etc/mountd.conf
>adb push init.rc system/init.rc
>adb shell
#mkdir /system/sd
#ls /system
(make sure a folder called sd exist)
#reboot
When your android reboots
>adb remount
>adb shell
#busybox df -h
Cross fingers, pray, beg, bargain and look for the line
"/dev/SOMETHING" "size data" "/system/sd"
in case this doesn't work i'm going to pm you my email, we can chat on google messenger and try and get this sorted

Quick question are you remembering to "adb remount" when you attach the phone - if you don't the phone wont be writable, which may explain the no space issue here:
C:\Users\Illuminator\Desktop\G2>adb push C:\Users\Illuminator\Desktop\G2\/mountd
.conf /system/etc/mountd.conf
failed to copy 'C:\Users\Illuminator\Desktop\G2\/mountd.conf' to '/system/etc/mo
untd.conf': No space left on device
*********but here you are trying to write to a location that doesn't exist, unless you see the magic line ending system/sd you cannot proceed
# busybox cp -a /data/app/ /system/sd
busybox cp -a /data/app/ /system/sd
cp: write error: No space left on device
cp: write error: No space left on device

Jesus this is killing me!!! yesterday i got all the way to step.12
And yes the sd came with the phone sdcard in fat32 -1.3gb followed by 0.7gb ext2 - yes that's correct.
And in case u where woundering then yes my phone is rooted wich was a pice of pie compered to this lol.

You're not kidding i've done this 5 times (on 3 phones - updates) never had this much trouble!
do you have the same problems if you sit the files on your sdcard and do the following? if so as much as it sucks to lose your data i would strongly suggest doing a wipe before hand (reboot phone holding home and at prompt alt + w)
>adb shell
#busybox cp -a /sdcard/mount.conf /system/etc/mount.conf
#busybox cp -a /sdcard/init.rc /system/init.rc
#mkdir /system/sd

C:\Users\Illuminator\Desktop>adb shell mkdir /system/sd
mkdir failed for /system/sd, File exists

fantastic, well that's something! how about the other two did both copy successfully? and if so does the magic line appear after reboot?

I can not understand why occupies 66% of the space is has NOTHING within the directory
I tried using the command "fastboot erase system", and the command says that cleared the system, but it does not clear these 66%
what should I do to fix this?

How can i erase block size?

Hi Guys,
I am facing a small problem that will not let me install any Android system on my device.
I have a BLU DASH 3.5 and the problem seems whenever I use the command "busybox df" ... it always returns me:
Code:
~ # busybox df
busybox df
Filesystem 1K-blocks Used Available Use% Mounted on
tmpfs 80612 48 80564 0% /dev
/dev/block/mtdblock1 225280 215936 9344 96% /system
/dev/block/mtdblock4 179200 1152 178048 1% /data
/dev/block/mmcblk0p1 3850240 118560 3731680 3% /sdcard
/dev/block/mtdblock2 61440 1180 60260 2% /cache
My folder /SYSTEM is always full.
I've tried deleting the folder using the "rm" command and it works, the command clears my folder / system, except that when I create the folder again using "mkdir" and remount the partition with the command: "mount -t yaffs2 /dev/block/mtdblock1 /system" the space occupied remains just seen... 96% used.
I tried to:
- delete /system folder
- delete /dev/block/mtdblock1 (also mtdblock2, mtdblock3, mtdblock4, mtdblock5 and mtdblock6) but when devices reboot, everything back as it was before.
- remount in other partition
I dont know what to do
is there any way to clean/wipe/recreate the /system partition?

[Q] s5570i - virtual sdcard

hi friends
on my s5570i, cause the sdcard reader is broken, i have created a virtual sdcard with this step:
1) dd if=/dev/zero of=/data/storage.img bs=1024 count=13000
2) mkfs.vfat /data/storage.img
3) losetup /dev/block/loop0 /data/storage.img
4) ln -s /dev/block/loop0 /dev/block/vold/179:1
5) mount -t vfat -rw -o dirsync,nosuid,nodev,noexec,relatime,fmask=0702,,uid=1000,gid=1015,dmask=0702,allow_utime=0000,utf8 /dev/block/vold/179:1 /mnt/sdcard
and now i see my virtual sdcard with "mount" command so:
/dev/block/vold/179:1 /mnt/sdcard vfat rw,dirsync,nosuid,nodev,noexec,relatime,uid=1000,gid=1015,fmask=0702,dmask=0702,allow_utime=0020,codepage=cp437,iocharset=iso8859-
1,shortname=mixed,utf8,errors=remount-ro
( is this correct? )
now...i can use it, copy file ecc, shot photo but only with ICS camera, and use normally with Root Browser Lite.
My question is.. why like Myfiles.apk or stock Camera.apk don't see the virtual sdcard as a real sdcard ?
What should I do to make it recognize at other app as for example Camera.apk or Myfiles.apk ?
I hope someone can help me
thanks friend
