Hi guys,
Can anyone offer me any advise with Apps to SD?
I have rooted my Hero and installed the RA-HERO-v1.2.3 recovery image.
I have then wiped my SD card and selected the option to partition the card in the recovey menu.
However when i boot up the Apps to SD application it says that my card doesnt seem to be partitioned correctly and wants me to set up the EXT2 partition?
After a bit of Googling i found theres some adb commands that can set this up after partitioning (which i assume is set up correct - any way to tell?) The commands are :-
Code:
adb devices
adb remount
adb shell
cp -a /data/app /system/sd
cp -a /data/app-private /system/sd
rm -r /data/app
rm -r /data/app-private
ln -s /system/sd/app /data/app
ln -s /system/sd/app-private /data/app-private
However i get as far as the cp commands and it says it is an unknown command?
Any help would be much appreciated - was up til past 2am this morning trying to figure this out with no luck
Thanks
Paul
Try this guide, worked perfectly for me.
Thanks for that - it at least let me check everythings partitioned up correcty.
Still Apps 2 SD wont work.
One thing i forgot to mention previously is that i'm using an official HTC rom - does this only work with custom roms? I thought the only requirement was Root access?
Ive spotted 2 versions of Apps2sd on the market
Apps2sd - gives error 'Either an incorrect ROM is installed or your SD card is not formatted correctly'
Apps2sd 2 - gives me the option of creating an EXT2 partition (with a slider)
Cheers
Paul
I'm not a 100% sure(maybe someone else can confirm) but yes I think it only works with custom roms. I rooted my Hero the day I got and have never used the stock rom.
Unless there is a specific reason you need to use a stock rom maybe consider using a custom one? Now that the source code is out I would have though more roms will be coming soon.

I just received my new 32gb SD card, and am wondering how to ensure that my ext3 partition is also copied over, not just the fat32 files. I have found some other threads regarding this process but I still have some unanswered questions.
FYI, I am using MIUI 1.11.4 on a rooted Acer Liquid E (and malez-recovery, which is based on CM).
1. The general consensus seems to be to do a nandroid backup, partition the new card with gparted, and restore that backup (and obviously copy the fat32 files to my computer and then transfer back). I'd just like someone to tell me I'm correct before I try it.
2. On every single one of the threads I found, it always says to do a nandroid backup. Do they really mean a nandroid+ext backup?! Will the basic nandroid backup do the trick (I don't see how)? I'm concerned about this because I always get errors when I attempt a nandroid+ext backup. I plan to run nandroid-mobile.sh -b -e via adb once my file transfer is complete (stupid slow old sd card + computer), but I'm not confident that it'll work. If it doesn't, what options do I have for accessing the ext3 partition? **UPDATE: I ran nandroid-mobile.sh, and it eventually said "--ext2 specified but unable to mount the ext2 partition". I'm still Googling but I haven't figured out a solution yet. Ideas?
3. Every thread recommends using gparted but provides no justification as to why. Since I am using Windows, the whole process seems over-complicated. Can I not just use the "partition sd card" available through recovery? Why is it better to use gparted?
Thanks for any help you can give a semi-n00b!

1. Do that (just do it ; in case anything goes wrong, you can restore the nandroid backup and have your device up and running easily). If you don't create one (make sure you do) you will have a hard time getting your device to work again (and depending on your device, it may not be fixable).
2. Just make a nandroid backup. Some roms have it enabled by default (access to the partition). See here: http://forum.cyanogenmod.com/topic/19160-modhow-to-apps2ext-for-cm7-updated-03312011/.
3. Using GParted is the easiest method (which is why it is recommended): http://gparted.sourceforge.net/.

I doubt that my ROM does an ext backup by default.... I have now run nandroid-mobile.sh and eventually got the following message: "Warning: --ext2 specified but unable to mount the ext2 partition". I'm still Googling but I haven't yet figured out a solution for this. In the meantime, I have copied /sd-ext to my computer, which might end up being a decent workaround...but I'd still love to know what's going on!
**UPDATE: Something I've noticed...:
If I access the phone after a "normal" reboot, /sd-ext definitely exists (I can see it using simply ls, and also mount and df), but no scripts are available in /sbin.
When I go into recovery, /sbin contains all the scripts (so I can now run nandroid), but /sd-ext doesn't appear!
I've a strong suspicion this is why the partition can't be mounted during the nandroid backup.
So how do I fix this?!

You cannot "fix" it. That is one reason but it also really depends on your device. For example: http://www.jayceooi.com/2011/01/12/...tition-on-sd-card-with-clockworkmod-recovery/ - This device is able to do it from recovery and it is easier than the GParted method (at least on that device).

I think we're mixing up 2 different issues now.
Forget the partitioning method, I'll just use gparted.
But now there's a major issue: I can't make a nandroid+ext backup. I've used adb to copy everything from my current ext partition and can load it onto the new card's partition, but that might not be an effective solution -- will it break all the symlinks? I'm trying to figure out whether symlinks ultimately store a path (therefore links won't break because the directory structure is still the same) or an address (which will break the links if I'm just copying + pasting). I'm finding conflicting answers.
So now I'm asking about what this error means (why won't it mount), whether the behaviour I described in the "update" above is normal (no sbin in normal mode, no sd-ext in recovery), and what alternatives I have! (Oh, and also my symlinks Qs) Plenty of people using the same recovery have created nandroid+ext backups without problems, and all the posts I'm finding about the issue relate to older versions of AmonRa.

It's quite likely that it will break the symlinks (just like .android_secure issues). Are you able to make a nandroid-only backup?

What recovery are you using (include version)? It is a known problem for some recovery not being able to have access to the SD-ext partition (e.g. ClockworkMod Recovery 3.0.0.5 on some if not all devices). So you should be able to access the SD-ext partition in recovery, and you should be able to access sbin normally.

Yes, I can do a nandroid backup of the internal partitions. Also not sure what issues you're referring to. I did some research on symlinks and posted on a linux forum and concluded that it shouldn't break....

(I don't have enough posts to insert URLs) I am using Malez recovery 0.6.1 (current is 0.6.2, nothing in the changelog suggests any relevant fixes though). I've searched extensively and it seems that I'm the only malez user having this problem.
Also, I can access sbin, but its only contents are adbd and ueventd. /sd-ext just plain doesn't show up in recovery mode.
Question: who is the owner of your /system, /sd-ext, and /system/sd partitions?
And a possibly unrelated question: what's the point of running a command through busybox (e.g., busybox ls instead of just ls)?

Busybox adds additional commands that the normal android command system does not have/understand on it's own (It gives you additional LINUX/UNIX based commands). See here: http://busybox.net/about.html.

When you run ls -l the 3rd and 4th columns show the 'owner' and 'group', respectively. It'll say things like root, system, etc., or maybe 0, 1000, 500, etc.

So there's no point in running a command like ls through busybox, right?
New question:
All that /system/sd contains is a 0-byte file called 'placeholder'. I can't find much info about this, but it sounds like this is intentional. But I know that this is where the ext partition is supposed to mount to. Does yours look like this (in either normal mode or recovery)? (edit: in recovery mode, the placeholder is gone, replaced with another 0-byte file called 'empty')
Also, do you think you could paste the output of mount when run in recovery?
BTW, A2SD seems to work perfectly otherwise. The only oddity I've noticed is that when I run a2sd forcecheck near the end it tries to unmount the partiton and can't.
Code:
[ ] Launching Apps2SD Start Program with forcecheck
[ ] Starting Darktremor Apps2SD in forcecheck mode
[ ] Creating Force Check Flag File...
[ ] Unmounting /dev/block/mmcblk0p2...
umount: can't umount /sd-ext: Device or resource busy
[ ] Rebooting phone...
Ironic that I can't mount it in recovery yet I can't unmount it normally!
Guys any idea how to change the default appdata storage...
\data\data\com.google.android.apps.currents
to
sdcard\Android\data\com.google.android.apps.currents
coz currents stores both cache and data to internal mem...which takes a whopping 100-150mb itself
can i change some vaules to make it store in the sdcard instead.....
I dont know why Google does some stupid stuff it does...
and pl dont suggest s2e app2sd, link2sd etc etc...
i already use s2e...w/o data moved ...
i want data on internal only

Just download 1Tap Cache Cleaner and clear your app caches once in a while. All apps accumulate some cached data so you can free space by clearing them. It's much easier this way.

Remap Cache folder to SD card
So the combined size of Currents cache and content is more free than your internal memory? Not a for sure fix, but looks like folks were able to use terminal commands to remap their market cache to SD card, could try modifying the instructions found here, but substituting the folders that apply to your problem with Google Currents.

That one I think I understand... but, unfortunately the answer is that the Dalvik cache partition (where the market APK's are downloaded to) on many original Samsung devices (i.e. Fascinate) is only about 35 MB in size. Anything larger will get rejected as being too big. Most of the newest devices have a larger download partition.
I've seen a few posts on different forums on remapping the download cache to a different, larger partition... but nothing specific to our devices. I've tried following other posts just to see if it works, but suceeded only in either having no effect or messing it up worse and having to reinstall the ROM (not a big deal, but frustrating).
Until one of the smart people here tells us how to remap **our** cache to a larger partition... I'd do a Google search for the APK of the app you are trying to install. That worked for me to install an app about 40 MB in size.
** edit **
I see that you were able to download the app after deleting everything in the cache folder. I guess your device is lucky enough to have a larger download partition than mine does
Glad to see you got it to work!
** 2nd edit - How to remap your market cache to the SD card **
-- UPDATE -- (Thanks to grickson here at XDA)
Problem: Insufficient Storage Space Available (Android Market)
Possible Solution: Remap cache folder to your SD card
** WARNING **
I am not responsible if you mess up your device doing the following. It manually remaps your market cache to your SD card to give you extra space. The only caveat is that if you remove your SD card (or while the SD card is unmounted) the market will not work. If you are worried about losing market functionality, DON'T try this. If you mistype (or the world suddenly tips over or some other unforeseen consequence), you can ruin your ability to run the Android Market at all. Please remember, you can repeatedly clear your Dalvik cache as often as needed to continue downloading apps. you can also get most larger APK's if you spend a few minutes browsing for them. You have been warned!
** END WARNING **
1.) Download and install a terminal emulator
2.) Open the terminal emulator and type su
3.) Allow the app to always have root access and exit
4.) Restart the terminal emulator and type su, the prompt should change to a #
5.) Type the following commands:
# cd /data/data/com.android.vending
# rm -R cache
# mkdir /sdcard/cache/
# mkdir /sdcard/cache/marketCache
# ln -s /sdcard/cache/marketCache cache
- What these commands do are (in order): change directory to your cache folder, delete the entire cache folder, create a directory on your SD card named cache, create a subdirectory in that one called marketCache, link the phone's market cache to the newly created folder on your SD card
To reverse this process (hopefully):
1.) Open the terminal emulator and type su
2.) Type the following commands:
# cd /sdcard/cache/
# rm -R marketCache
# mkdir /data/data/com.android.vending/cache
# ln -s /data/data/com.android.vending/cache cache
Alternately, (from what I understand) you can just repartition your device and reinstall your ROM of choice using ODIN and your market should be back to the way it was.

I have the same issue. Since this was posted 2 years ago I hope you have solved it. I want app data which gets download internally to be saved in my internal storage.
I have edited the apk so that it gets installed in my internal storage but I can't find a way for app data.

sorry for late reply, i didn't find any promising solution and finally got myself a phone with bigger space.
Its 2020 , has anyone found a way to change apps data path ? I thought could fix problem when trying Kali linux on phone even though moved it to sd card . I installed VMOS and moved it but same problem .
Hi, I'm using an LG Optimus L9 and running 4.3 bassed PAC-man rom.
The internal memory is 4GB and after installing a few apps, I started getting "Not enough storage space" warnings.
So, I checked the /data folder and found that there's directory called lost+found which is taking up a lot of space (Above 1.5GB).
I tried deleting files using ES Explorer with the data folder mounted as R+W, but it says "error deleting files"
Is it safe to delete the lost+found folder?
And if yes, how can I delete it since I'm unable to delete it with a file explorer app.
It would be really great if could recover thelost internal memory

Using TWRP.
If I backup first, it will also back up the lost+found data
And restoring data will bring it back.
I did format data and system before flashing the rom. So I don't know why the lost+found has so large size.
What should I do?

I was having the same problem. My phone is Samsung Galaxy S2 (GT-i9100). I was on stock Jellybean. But it was starting to feel sluggish and slow. So, having heard about the new Android Kitkat's lower memory requirements and smoother performance, i decided to install Cyanogenmod 11 on it.
Installation was not without problems. At first i flashed Clockworkmod Recovery 6.0.2.9. The phone bricked into a bootloop with a yellow triangle on it. Flashing the Cyanogenmod 11 resulted an error of "Status 7". So i searched for the latest Clockworkmod Recovery, which was at 6.0.4.5. After flashing the 6.0.4.5, Cyanogenmod 11 installed successfully. Performance was really smooth. No lags, no jitter, and everything worked like a charm.
The problem started when i re-installed my applications. Suddenly i got a message of "insufficient storage". This has never happened before. Note, that i previously had large games on my phone like Real Racing 3 and Bard's Tale. This time, i haven't even installed those large games. So i looked at my Storage, and found out that i only had 141mb of free space. But the weird thing is, my reported Apps was only 353mb, from 1.97GB internal storage. So there was over 1GB of storage just vanished.
I browsed for a solution to this problem, and landed on this thread. After reading reply from fabiosirigu, i decided to brave myself, and deleted the content of the lost+found folder (but not the folder itself). I accessed the folder with the built-in File Manager from Cyanogenmod, and set it to "Root Access Mode", and select all folder in the folder, and deleted it. The deletion took quite a few minutes, which felt like ages. Just sat on my bed, crossed my fingers, hoped that nothing will go wrong.
After the deletion, i rebooted my phone. the cyanogenmod logo appeared, and the system booted as usual. I just exhaled a massive sigh of relieve. I went straight to the internal storage, and now it is showing the correct report, 1.67GB of free space.
Thank you for your reply fabiosirigu. Really solved my problem.
lost+found genesis
Let somebody correct me if I'am wrong.
lost+found directory is standard for some unix/linux filesystems. All ext(s) 2, 3 and 4 contains it by default.
The operating system collects unidentified, broken files and its parts inside of l+f dir.
No one of these junks is used by running system.
So - you can look in l+f for some lost, missing files. If you don't miss for any (who knows it better?) then you don't need l+f content.
This is a mystery. I have a Verizon Samsung Galaxy Note 2, running 4.1.1, rooted. A few days ago I ran out of space on the internal storage so I wanted to move /data/media/Download to /mnt/extSdCard/ and then symlink to it. But I screwed up and accidentally moved all of /data/media to the external SD card. I realized I did that and immediately moved it back to /data/. I did this using the Move command in RootExplorer.
Now I find I can no longer write to /storage/sdcard0/. For example, my S-Note files go there but when I try to save a note it says "Unable to save file". I have another app that also keeps data there and it too complains that it can't write to its own directory on /storage/sdcard0/. I also find there are files on sdcard0 I can't delete myself either with RootExplorer or from a terminal window, even with a "#" prompt.
/sstorage/sdcard0 has perms of 775, owned by root in group sdcard_rw. /storage has perms 775, owned by system in group sdcard_r.
I'm really stumped here. What the heck did I do to my phone? Any help would be *greatly* appreciated. Thanks!

This is a mystery. I have a Verizon Samsung Galaxy Note 2, running 4.1.1, rooted. A few days ago I ran out of space on the internal storage so I wanted to move /data/media/Download to /mnt/extSdCard/ and then symlink to it. But I screwed up and accidentally moved all of /data/media to the external SD card. I realized I did that and immediately moved it back to /data/. I did this using the Move command in RootExplorer.

Do you have a nandroid backup? extsdcard and sdcard0 will stay untouched but maybe all you need its the system and data back to working order. I figure that's the first idea. I couldn't say what's happened though.

That would be nice but unfortunately I don't have nandroid. I just back up my files to the external SD card with Titanium Backup and then store a copy on my PC. To be honest, I was afraid of screwing up something by running nandroid so I never got it.
In the meantime, none of my apps that are parked on /storage/sdcard0 run anymore, all claiming they can't create files there. The only thing I've been able to do there is chmod and chown but it doesn't seem to help. If I delete a file with Root Explorer, it says it's deleted but when I refresh the directory, it's still there.
I don't see how the two could be related, but I keep coming back to /data/media. I also have a Galaxy S3 that's working. /data/media on the S3 is 775, whereas it was 770 on the Note 2. I changed it to 775 and rebooted - didn't help. I changed the group of /storage from sdcard_r to sdcard_rw - didn't help either.
Could you tell me what the properties are on your Note 2 of /data, /data/media, /storage, and /storage/sdcard0? I'm thinking that Root Explorer munged up something when I moved /data/media/ to the extSdCard and then back again. The subdirectories and files are all there but sdcard0 isn't happy now.
Thanks very much for the reply.

Did you want to know what permissions those directories have?
/data rwx rwx --x
/data/media rwx rwx ---

Yes, thanks. That's the same I have on the Note 2, so that's not the problem (though oddly enough, on the S3, /data/media is rwxrwxr-x).
Still, it has to be *some* permission somewhere that's wrong and is preventing apps from writing or deleting files they have in sdcard0. What about /storage? I've got:
/storage r-xr-x--- owner=system, group = sdcard_r
/storage/sdcard0 rwxrwxr-x, owner = root, group = sdcard_rw
/storage in particular doesn't seem correct. ???
FWIW, here's someone else with the exact same problem - unfortuntely he didn't get a resolution: http://androidforums.com/android-lounge/716573-unable-delete-move-files-directories-sdcard0.html
And this one too: http://android.stackexchange.com/questions/30113/cant-delete-any-files-in-my-download-folder I tried the same things suggested there and they didn't work for me either.
I dont know enough about the permission system. You said you tried terminal. Maybe try another root enabled file explorer. I've only used es and root browser. Maybe your binaries need to be updated.
You might consider starting fresh if you can't find a solution. From here on out I'd take care to be meticulous and read up on the how to threads for rooting and unlocking bootloader just so you have an idea of where what your going to do fits in with everything else. It sounds like you've just beet rooted and left your phone stock.
Perhaps the internal memory need to be reformatted and everything taken back to a stock working order? If your bootloader is unlocked and you have a custom recovery (like twrp or cw) you could back up all contents of your ext and internal sd to a computer, do a nandroid backup(just in case), and back up your apps with titanium, then wipe everything, system data cache dalvick through recovery then reformat internal sd and re flash the stock rooted image of 4.1.1 or 4.1.2.
If your bootloader is locked up still you could use Odin to get back to stock factory image. You would no longer be rooted but you can then reroot. This is always the end of the line and one can run into some bigger problems here.

Yup - I've tried Root Explorer, File Expert, Terminal Emulator, and adb USB from the PC. Same result from all of them. Oddly enough, Root Explorer and FE both claim that files I select on /storage/sdcard0 have been deleted, but when I refresh the file list, they're baaaack...

Yes, I only flashed the Verizon rooted stock ROM because that's all I needed. I just want to be able to use apps like Titanium Backup, get rid of that stupid clicking sound the camera makes, and other things you need root for. I'm happy with the other features of the standard ROM. I never bothered unlocking the boot loader.

Yes, I've considered that, and it may come to that. But it's not a very intellectually appealing solution. It's sort of like burning down your house because you've got termites. I'm still hoping there's a less drastic solution. In the meantime, this may be locking the barn door after the horse is gone, but I downloaded a nandroid app and took a nandroid backup. Don't know if wiping and then restoring that will also restore the problem.

Yup, if that doesn't do it, it's time for a new phone
UPDATE:
I started looking at /data/media and comparing permissions there to what my S3 was showing. It seems /data/media was owned by media_rw in group media_rw on the Note2, but owned by root in group root on the S3. So in adb on the Note 2 I did #chown root:root /data/media. To my surprise, that worked. I then changed the permission from 770 to 775 to match what the S3 has. I then tried saving an S-Note - didn't work. So I went into /data/media/S Note and changed *its* owner/group to root, and permissions to 777 also. I tried saving a note and ... success! It saved it OK.
I'm starting to think that when I copied /data/media back to /data from /mnt/extSdCard/data/media, Root Explorer bollixed up the owner/group/permissions. I'm going to try some other directories there and see if that helps too. And see if this survives a reboot. So that's some progress at least...
That is indeed good news. At least the permission will work through terminal on a subdirectory basis in the media dir. You could recursively change permission for all subdirectory in media. I belive -R probably best to Google that.

Well that seems to have done it. Everything is working once again. In the final analysis, it appears that you just can't change permissions or delete files from /storage/sdcard0/. However, this is apparently just a mount point (I may be wrong here) for /data/media/ and you *can* change permissions/owners/etc. there. Once I did that, the apps I had that had installed themselves on sdcard0/ started working again. Go figure.
And as a bonus, I got the motivation I needed to start doing nandroid backups and learned a little about the storage hierarchy of Android. So big thumbs up for taking the time to read all this and help me out.

Yeah I leaned more bout this too. As an after thought, I have only ever moved items from sdcard0 to extsdcard by going to /storage then copying items from one to another. I too believe this is just a mount point. Nevertheless, probably most items in /data/media you were trying to move to extsdcard are found in sdcard0 and accessible through the mounting folder: /storage, well at least /downloads are there in /storage/sdcard0/ and i have always navigated to /storage first then to /sdcard0/ to grab /downloads or /android/data/ to copy to external whatever.
I know the thread is more than a year old, but I have the same issue here on the Xperia T.
Can't write on /storage/sdcard0
However, I have no idea what to do to fix it. I found a step by step actionplan here:
http://forum.cyanogenmod.org/topic/104879-cm12-issue-with-sd-card-and-wifi-network-detection/
is this what you did?
