New and improved Apps to SD(more stable, more powerful, etc) Tutorial

Well, some of you may have heard my ramblings around here that I've been working with some of the devs here(JF and MartinFick deserve major praise, probably more than me) on getting a better way to do the whole apps to sd thing.
After 3 days of talking/discussing/working on it, I've finally reached the fruits of that investigation and thought I'd share. This new method uses the filesystem unionfs to essentially meld the /data directory with the /system/sd directory, so that they appear to be one. This has the potential to allow users to move specific apps to or from the sd card, is far more stable than the normal symlink method(will still boot, etc even if there's no SD card) and should be easier to set up. Now, onto the tutorial of setting this up.
BIG DISCLAIMER NOTE: This is a major hack of the phone and it is fully possible that it will break your phone(I've seen no permanently bricked phones but that doesn't make it impossible). Use this method, and my app along with it at your own risk.
REQUIREMENTS:
1: This only works on JF(possibly only on 1.5, not sure about the others) and The Dude's v.1.0 or greater. The Dude's 1.0 or greater actually does the steps in this tutorial for you so you can just run appstosd2 and set it all up from there if you're using his ROM.
2: This still requires you to have 2 partitions set up, first FAT32 and second ext2. Although you can use the appstosd2 app attached to this post and available in the market for $0.99 which will partition the card for you.
3: If you want your apps to go to the sd card, you must have a directory "/system/sd/app" If you didn't have apps to sd before on the ext2 partition do the following in terminal emulator or run my appstosd2 app after finishing the tutorial:
Code:
su
mkdir /system/sd/app
If you want the private-apps, or dalvik-cache moved you can replace "app" in that code with ""app-private", or "dalvik-cache" respectively. Do not copy "data" to the sd card. My script will delete it on the next reboot.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------
Alright, first there's some files you need.
1: init.rc in .zip attached to this thread
2: a2sd.sh in .zip attached to this thread
All the above listed files should be put on your sd card(my tutorial will assume they are in the root directory of the sdcard(the topmost folder)
-----------------------------------------------------------------------------------------------------------------------------------------------------------------
If you need to undo the normal apps to SD first do the following in the recovery terminal(it's not strictly necessary but I'd recommend it):
Code:
mount data
rm /data/app
mkdir /data/app
if you moved the dalvik cache, repeat steps 2-3 with "dalvik-cache" instead of app. Ditto with "data" for the data cache.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------
Then go to terminal emulator and type the following:
Code:
su
cp /sdcard/init.rc /data/
cp /sdcard/a2sd.sh /data/
Then reboot and you're set. By default all future apps are installed to the sd card. In order to move an app to the internal memory do the following in terminal emulator:
Code:
su
cp /system/sd/app/[the app you want to move] /system/intmem/app/
rm /system/sd/app/[the app you want to move]
I will be incorporating this into my appstosd app soon(probably as a JF and TheDude-only version until the rest of the devs get on board).
I have included a copy of appstosd 2, which will copy all apps from internal memory to the sd card with an option to remove them from the internal memory. This will only work if you have followed this tutorial.
If you don't have partitions set up, appstosd2 will now do that for you with user-set partition sizes.
NOTE: If you're using The Dude's ROM and find yourself with an outdated version of this since he doesn't always update his ROMs at the same time I update this, do the following in terminal emulator to update(after putting a2sd.sh from the attached a2sd.zip on your sdcard):
Code:
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
rm /system/bin/a2sd.sh
cp /sdcard/a2sd.sh /system/bin/
reboot
For JF1.5, do the following to update:
Code:
su
rm /system/intmem/a2sd.sh
rm /system/intmem/init.rc
cp /sdcard/a2sd.sh /system/intmem/
cp /sdcard/init.rc /system/intmem/
reboot
NOTE FOR UPDATERS: If you had your data on the sdcard(/system/sd/data), it WILL GET DELETED with the new version. This is a necessity in order to get both wallpaper and protected apps working. I recommend moving it back to the phone.
EDIT: And here's another tutorial from ThatsBS(might be easier for the less tech savvy to follow?):
I am still learning a lot everyday from this forum. So for people new to this process let me noobify it, if I can, as I am one too.
Start by reading the first page!! Get all the stuff you need from page 1. (apps2sd2.zip and a2sd.zip )
I started from a fresh wipe and flash of jf1.51 adp.
A newly formatted fat32, non partitioned sd.
Put the init.rc and app2sd.sh on the sd (the files NOT the zip)
Then go to the terminal emulator and typed:
su
cp /sdcard/init.rc /data/
cp /sdcard/a2sd.sh /data/
Then reboot
Next I ran the apps2sd 2 app. It will ask you how much to you want to partition. I did 3000mb the first successful time and the dreaded low mem notice would not leave the status bar. I have read not to make it more then 1500mb. Have a good connection, dont force close it. It will reboot.
Next, after the reboot, I ran the apps2sd 2 app again and pressed "copy apps to sd" (let it do its thing)
Reboot.
Next I went back to the emulator and typed:
su
mkdir /system/sd/app-private
mkdir /system/sd/dalvik-cache
Reboot.
Go back to the apps2sd 2 app and hit move dalvik-cache.
Reboot for good measure and your done.
I did this in about 10 mins. Worked flawlessly.

I have a ?, if i have been using your app what dod i do diferent or what should i change?
Thanks

Good job, thanks!

JF1.5 build has already unionfs.ko in it, doesn't it? Is there any difference between this unionfs.ko and the one included?
1. I hear unionfs is not really stable at this point, is it true?
2. Why do you want to move the whole /data folder to sd, instead of just /data/app, /data/app-private?
3. You might want to add a command to remove previous app2sd changes (i.e. delete symlinks, create folders.)
4. How do you put selected apps to internal memory after this? Copying to /data will copy to sd card again.
The whole idea is really interesting! Thank you for your work!

You don't have to do anything different. It will find all the apps you put on the sd card. If you want to set the phone back to normal(so the phone memory apps can still be there), you can do the following in the recovery terminal:
Code:
mount data
rm /data/app
rm /data/dalvik-cache (only if you moved the dalvik-cache)
mkdir /data/app
mkdir /data/dalvik-cache
@Dimath: yes, I did mean SD card, good catch
1:JF didn't mention it and from a little bit of using it, it seems stable to me. Plus, no matter how much I've screwed up, I haven't managed to boot loop my phone yet.
2: You could just mount those independently. I might end up doing that eventually but for now the way it is works for reasons I'll get to.
3: True, although it's not strictly necessary. If apps2sd already works, this won't break it. I'll put in a guide on undoing the symlink method
4: Actually, no. My script sets the internal memory as the main file system in the union, so apps automatically go there. Moving apps to the sd card just involves copying them to /system/sd.

Ok, just a little confusing.
I didn't use the apps2sd to move apps over to my SD card. What I did was set it with the busybox ls command. I guess that's the symlink.
My question is, if I didn't use apps2sd, can I still use your method? I also moved the dalvik cache also, everything works fine for me now, my apps go directly to the SD card when installing since my memory stays at around 65 MB no matter what I do.
Just need some laymen terms to help me understand that if I'm NOT using apps2sd, and I just linked them with the recovery method, what's my pitfalls / advantages?
Thanks.

Yes, any other method of apps to sd currently uses the same symlink method, so following the directions as if you installed my app will work. A note though is that all future apps will install to the internal memory by default. I did that because it's MUCH easier to move apps from the memory to the sd card than vice versa. You can use the code I posted if you want it the other way around.

would this also work for /data/data and app-private?
or is this particular setup only for dalvik-cache and app?
oh and before I do this, just wondering, so in theory, since I have a 1.5GB ext2 partition, my free memory will be 1.573GB (1.5GB + 73Mb internal)? The internal memory will just run down and switch over to the sdcard when needed (but be seen as one filesystem)?

This works for the whole /data folder and everything under it. Everything is automatically installed to the phone memory right now so you can just move over anything you don't want on it(will be making an app to do this automatically)
EDIT: oh and anything you already moved over to the sd card will still show up.

Code:
su
mount -o remount,rw /dev/block/mtdblock3 /system
cp /sdcard/unionfs.ko /system/
cp /sdcard/init.rc /data/
cp /runme.sh /data/
cp /sdcard/a2sd.sh /data/
I see, when I run these lines of code (I can do this from adb also right using adb remount) this IS the new symlink method. It's just all at one time without me having to manually link anything.
Right?

Wrong, no symlinks here. Pure unionfs goodness. Basically it convinces the operating system that /data and /system/sd are the same thing. So anything that's on /system/sd shows up under /data but everything that's normally under /data is still there. Think of it like what happens in windows when you merge folders with the same name, but in this case in actuality everything stays exactly where it was.

New news: If you haven't seen it, I updated this tutorial(and the scripts with it) quite a bit and would now consider it to be completely fully functional.
Also The Dude will be sending me an advance copy of his next ROM tomorrow to verify it works. In his build the apps to sd will be automatic, with no user setup(although if you want apps on the sd card you'll have to make an app directory under /system/sd(mkdir /system/sd/app), ditto for dalvik-cache and data).
Finally, I will attempt to add this into my apps to sd app tonight, thus rounding out everything I can do.
After all this, the only thing left is for Haykuro to build it into his ROM and me to make an app to move specific apps to/from the sd card automatically.

This will no doubt be the method of choice in no time. Great work. Sticky?

If anyone dl'd the latest version(that fixed the race condition, etc), please download the one I just put up. I made that one in windows and I believe the funky carraige return(that indicates a new line) that windows uses screwed it up

So I got some kind of error, and I don't know what is going on.
I put in all the lines in the terminal emulator app..
but after line cp /runme.sh /data/ it gives me an error
it says "cp: cannot stat '/runme.sh': No such file or directory
Any help? I rooted my phone just so I could run my apps off of my SD card.. and now I can't figure out how to get it to work. Somebody help me please.

Ok, I am going to re-partition my memory card.. and then re flash to JF1.5 and try it again.

Just tried it, one issue I'm seeing is android seems to install [email protected]@[email protected] into /system/intmem/dalvik-cache at boot. Is there anyway to have that only in my dalvik-cache on the sdcard?
Its a fairly large file at 3megs so I want it to reside solely on the sdcard and even if I delete it from intmem, whenever I reboot it gets added again.
Now when I display the internal phone storage from the settings menu, it shows up at 835 megs.
I wonder if this is possible to use unionfs and make an ext2 fs object as a file on the FAT fs. That way no 2nd partition is necessary. Plus, if you remove the sdcard, everything will still work.
Maybe we could combine unionfs and this method that uses an ext2 image on the fat32 for apps to sd.

I've been looking at that possibility with JF and MartinFick as well, seems like it could be a good plan but I wanted to get this bit done first. It's a good point about the dalvik-cache, but in order to fix it JF(in this case) would have to change /init.rc to make sure to do this bit before building the dalvik-cache.

Can't download apps from market
hmm so I didn't hit any errors when doing this, but afterwards I am unable to download any apps from the market. It just continually says "Starting Download..." Everything else seems to work well.
I had this same issue when I tried to manually setup apps to sd using the symbolic links. I narrowed the issue down and figured out this only occurred after I moved the dalvik-cache over to the sd card. I'm assuming I'm doing something wrong, but can't seem to figure it out. Any pointers in a general direction would be most helpful
I'm using JFv1.50 ADP1.5, not the modded version by LucidREM. For some reason the bootloader couldn't pickup his version on my phone and --edit-- I'm pretty sure I have the SD card partitioned correctly... everything else seemed to work ok. The ext2 partition shows up as the correct size
*EDIT* So apparently my issue was the SD card as well. Just did a format of the sd card and it fixed it. I also formatted data and cache (alt+w in recovery mode). Thanks MarcusMaximus!

If I have apps2SD and the dalvik-cache both moved on the dudes builds already, do I still have to create those directories or will my existing setup still work fine? I would like to know what kind of issues I may run into when the dude releases .95 with this (hopefully, not getting my hopes up just in case).

How to get more internal space on galaxy fit

firstly I'm not responsible for any kind of damage caused to you
but I have tried all the things on my galaxy fit before explaining here
It's not copied from somewhere instead It's based on my experience on my galaxy fit.
For Non Rooted Devices
There is nothing other then using app2sd apps. Then move all the movable items to sd card. After installing app2sd all newly installed apps are automatically moved to external storege.
I uses app2sd by sam lu.
But for non rooted users I will highly recommend to root there device and make the best use of this smartphone.
for beginners everything about rooting/custom roms/nandroid backups etc is explained in this thread
http://forum.xda-developers.com/showthread.php?t=1606380
thanks a lot to A.cid for this wonderful guide
For Rooted Device
apps required
1.Root explorer or similiar
2.Link2SD (Link2sd Setup is explained later in this post)
step 1.Removing Useless system apps from stock or custom rom
go to /system/app using root explorer and mount as r/w
now delete unwanted apps
I will prefer freezing the app first using link2sd and then if phone is working fine then you can unfreeze and then delete that app
Step 2. Removing dalvik cache files
go to /data/dalvik-cache
now search for the dalvik cache files of deleted system apps
it will having name like
[email protected]@[email protected]
delete this file
Step 3. Linking files to Sd-ext or second partition of Sd card
if you have finished Link2sd setup then you can proceed further
open link2sd and then create Link for all the apps you want to linked to sd card
check all the 3 box 1. link apk 2. link dex 3. link lib files
and then your app will be moved to the sd-ext partition
if there are apps which are used very frequently then i prefer not linking dex files to sd card. link only apk for them.
currently system apps can't be linked using link2sd
In the case if app is not working properly after linking then remove links for that app.
Plz help me to improve this article.
suggestions and questions are welcomed.
forgive me for my poor english

Plz help in improving this article. If there is anything wrong in this post let me know. and if you have any other simple method to do this plz post here and help beginners to get more space. But try not to post complicated method which beginners find hard to perform

Link2SD steup on galaxy fit
Copied from A.cid main article from
http://forum.xda-developers.com/showthread.php?t=1606380
There are a lot of ways and scripts to transfer apps from your internal memory to the sd ext partition, but the most consistent method I found was Link2sd.
This method works across all roms (rooted stock and custom, both) that I’ve tried, even on all variations of CyanogenMod7 (CM7) as well as on ICS CM9, and is very easy to setup and use.
However, if a custom rom already has DarkTremor's a2sd (a2sdgui app will be present) or any similar script, then DO NOT configure them.
for example: Creeds v3 has a2sdgui, and if i want to use Link2sd, then after flashing Creeds, i SHOULD NOT run a2sdgui, and directly install (and configure) Link2sd...if you run/configure a2sdgui, then it will clash with the working of Link2sd.
Similarly, if any custom rom has any memory hack already implemented, then you cannot use Link2sd...
Steps to setup Link2sd:
• Download Link2sd from Play Store (it’s a free app).
• After it gets installed, run it, and allow root access.
• You will get a message to select the format of your sd partition, select “ext3”.
• Link2sd will then automatically create mount scripts that it requires to work, and will then tell you to reboot your phone.
• Do a proper reboot, and not a ‘hot reboot’.
• After rebooting, open up Link2sd, press menu then select “settings”.
• Select/check the options “automatically link newly installed applications to sd”, “auto link notification”, “relink lib files at boot” (and “fast scroll”, if you want).
• For “install location” option, select “internal”.
• Then go to “auto link settings” and select/check all the three options (you can skip/ unselect “link dalvik-cache file” if you wish)
• Done
Now, every new app that you will install will automatically be moved to your sd ext partition.
Link2sd is also an excellent (and fast loading) app manager, with which you can freeze, uninstall, re-install…though you can move only user apps to sd-ext partition.
Also, there is no point in having your entire phone memory empty, so you probably should unlink the dex (dalvik cache) of your apps. I usually link only the apk and lib files, and leave the dex files unlinked and on the phone storage, so as to avoid any sluggishness in operation., though if your phone memory still fills up, you can link the dex of your rarely-used apps, and leave the dex of important and frequently used apps on the phone storage.
Suppose a custom rom has s2e/app2sd pre-implemented, then after a fresh install, FREEZE the app (rather than uninstall), and then install Link2sd...
Also, if you get error "mount script not created", then choose partition as ext4 (rather than ext3 mentioned below), even though your partition might be ext3...(don't know why this happens with some roms )
In some custom Roms Link2sd doesn't mount sd-ext partition even after selecting correct type of partition in that case try to select other types whether they are working or not
Like in Chocobread v3.2 it worked after selecting partition as ext4

What happens when we install a new app??
I'm not a developer but this is what I experienced
/data directory is the space which is shown as Internal Storage in phone
/system directory has nothing to do with this internal storage
when we install a new app then it during the installation process three things happens
1.it creates an apk file in /data/app
2.creates an .dex file in /data/dalvik-cache
3.creates one folder in /data/data
when we move apps to sd that apk file moved to sd storage in
.android secure folder and creates an .asec file there
so basically that .dex file and data files are responsible for eating our internal space and for the apps which can't be moved to sd that apk file is also responsible.
we can't use widgets if app is on sd storage.
so in order to use widgets we have to move back to internal storage.
this is where Link2sd helps us
link2sd links selected files to sd-ext partition and for system it still appears in internal storage but it's not there actually.
While for system apps
.apk files remains in /system/app
only .dex files are in data/data directory
we can use widgets of system apps even apk files are not in /data/app directory
so it is recommended that if you want to use widget of the app but you don't want it on internal space(as it is using much more space while it is in internal memory)
here is the solution
create an apk file for that app using any backup app
then move that file to /system/app
change the permissions to rw-r--r--
for this simply see the permissions of any other system app and apply same here
to system

partition ur sd card through cm recovery then install s2e from play store now all cm7 rom come with pre install s2e script .

Another way is to use terminal emulator .
Download terminal emulator from the PlayStore and then run the following codes:
Code:
su
*grant/allow superuser permissions*
Code:
pm set-Install-Location 2
exit
exit
Note: sometimes if you get an error you may have to run
Code:
pm setInstallLocation 2
if it fails.
All this does is it allows moving many apps that aren't normally movable to the SD card. After running these codes you should be able to move apps to the SD card via Settings>Apps.
This code also sets the default location for apps to install into as the SD card.

What i do for more internal memory..!
Partitioning your sd card is an option. But if you have a sd card of less storage then this option is ruled out. I use a 2gb sd card and partitioning it is not very feasible for me. so...
1. If I'm on a stock gingerbread ROM i use this script http://forum.xda-developers.com/showthread.php?t=2303856 .
(I dont use it very often. Only if necessary.) And i odex the ROM if it is de-odexed by using http://forum.xda-developers.com/showthread.php?t=2303856 Universal Odex Script by MatrixDJ96. Odexing works very well!!! :good:
2. For a custom ROM not many modifications are needed. I just remove the unwanted apps using Link2SD. :good:

[Q] Link2SD not re-mounting the partition after flashing new ROM

Hi,
First of all, thank you a lot for all the development effort that has been put in to bring the AOKP ROM up to this fantastic standard. I have been using the ICS AOKP for quite a while, and just switched over to the JB ROM. It feels a lot faster and smoother, thank you!
I have got a question on Link2SD after flashing this ROM. Apologies beforehand, if this is not the forum to post that. I had used Link2SD while on ICS to move most of the apps to the SD card. Now after flashing JB, Link2SD does not re-mount the SD card secondary partition. I selected all the options mentioned (ext2/3/4/FAT) but it fails to mount with any of those options. So I'm not able to re-link any of my apps. Does anyone know how to fix this and get my apps back?
I also tried the following as per suggestions in some of the threads: 1) mounting it in recovery: not working; gives the message error mounting sd-ext (2) deleting some of the apps like Downloads and Email: still not working even after deleting those two apps.
Any help will be much appreciated. Thanks in advance!

I never had any problem with link2sd and ANY rom. Im on CM 10.1
Till ICS it was easy to directly download and flash roms and Gapps.
But JB roms need trimming.
What i do is.. after a clean wipe I flash any JB rom. Then remove unwanted apps.. Instal Link2sd..
change few minor system apps to user apps (not recommended, if you dont know.. what you are doing).
After linking these apps.. I always have enough mem for Gapps.
In Gapps also you have few apps which you can convert to user app and then link it.

After linking these apps.. I always have enough mem for Gapps.
In Gapps also you have few apps which you can convert to user app and then link it.

My issue is now fixed, but in a hard way. Formatted the secondary SD card partition, and then Link2SD automatically recognized it. All the apps are gone, but at least I got the secondary partition active. Spent another half-hour downloading all the needed apps again from the Play store.

Link2Sd not working for me on CM10.1 Rom
I am using TouchWiz JB V2 Rom
I have tried ti install int2Ext+ (CronMod Fixed version fro 4.2.2) Still no luck

Hi
І have also had the problem.
I removed the system software of Google voice search, voice dialing, search . (Titanium Backup / un-install all user & system apps)
format ext2 or ext4.
Run Link2sd
Apparently there was no room in the system or chmod / chown

Can you tell which version of kernel you are using?
If you are on 3.x.x version, sorry to tell you that these scripts are not working till today.

Thanks a lot man Pavai

The standard and not-really-necessary idea of doing a factory-reset wipe when flashing is the problem here. I also had that zong my sdext making it read-only and nothing, nothing except re-partitioning the sdcard helped.

not working !
hi ! I have a problem , I've tried to partition sd card with cwm, minitool partition , tried ext 2,ext 3 , ext 4 , flash again ROM , install first link2sd , recreate mount scripts every time i change the method but no matter what i do , it keep telling me that the 2nd partition is not mounted and wont let me recreate mount script . ( Mount script cannot be created ) . If anyone can help me , i'll very much appreciate . Thanks !

Hi,
First of all, thank you a lot for all the development effort that has been put in to bring the AOKP ROM up to this fantastic standard. I have been using the ICS AOKP for quite a while, and just switched over to the JB ROM. It feels a lot faster and smoother, thank you!
I have got a question on Link2SD after flashing this ROM. Apologies beforehand, if this is not the forum to post that. I had used Link2SD while on ICS to move most of the apps to the SD card. Now after flashing JB, Link2SD does not re-mount the SD card secondary partition. I selected all the options mentioned (ext2/3/4/FAT) but it fails to mount with any of those options. So I'm not able to re-link any of my apps. Does anyone know how to fix this and get my apps back?
I also tried the following as per suggestions in some of the threads: 1) mounting it in recovery: not working; gives the message error mounting sd-ext (2) deleting some of the apps like Downloads and Email: still not working even after deleting those two apps.
Any help will be much appreciated. Thanks in advance!

Hi, you can do one of these things, by adb shell run e2fsck -fpDC0 /dev/block/mmcblk0p2 to your second partition or using gparted run a full check of second partition of your SD card in a computer card reader, after that will work. I have the same problem, but in my case i have to do this procedure EVERY DAY because at next start the read only problem starts over... ANY BETTER SOLUTION APRECIATED !!!

After factory reset, I had a read-only ext4 partition. Had to start over.
Common cause of link2sd not creating its mount scripts is too little room on /system. Try adb shell df | grep system. Need a few meg. If this be the problem, need to trim the ROM.

Can,t understand ... How to Do it In Micromax A27...in custom Rom
tell me how to do it in Micromax A27 in custom Rom Dreamboltxv2

A lot of separate issues here and in various threads:
1. Sd-ext read only after factory reset. I never do that. Had that very thing happen. Save all data from partitions to computer, repartition and copy it back.
2. Not enough room on system to process/form mount script. JB and onward, ROMs need trimming. > 3meg needed, 9meg should be plenty.
3. No room on data. Link2sd can still work and fix that. If sdext can be mounted, that is ... and a launcher can live long enough to get to lin2sd and start it!
4. Other errors creating the mount script. I am now getting "device busy ... maybe ext4 not supported ... try vfat ... etc." Ext4 is supported. I have a copy of the script which I can place myself.
5. Data integrity problems in Kitkat based ROMs. Repeated recreation of dexes on data, using it up (Link2sd's Achilles heel). Sometimes, recreating that script can stop this. If one can get it re-created. Issues 3, 4. Link2sd can get the space back, problem is keeping it.
I have raised the issues with Link2sd authors.

Link2SD Mount Script Error. [4]: can't create /system/etc/init.d/11link2sd

I have a Micromax Canvas Fire A093 (rooted). I had been using Link2SD Plus without any problems until the night I was forced to factory reset my device because a friend of mine set a pin which he forgot.
I installed every app successfully except Link2SD. Although, I could install Link2SD but I could not make it run. The problem sets in when I try to create mount script. It says, "Mount Script Error. [4]: can't create /system/etc/init.d/11link2sd: Not a directory".
I browsed to the /system/etc/ folder using ES File Explorer only to find that there is file named init.d (and no folder as such). It contained some strings and nothing related to Link2SD. I even tried to create a new folder named init.d but the operation failed. I also tried copying a blank folder named init.d (created somewhere else) but nothing happened.
I reformatted my 2nd partition of SD Card with ext2/3/4 or FAT and filled with zeroes; the error still persists.
I hope experts here at the XDA may help me out sorting the problem.

Try installing universal init.d from Google play store.

try using foldermoumt for the same purpose for which you are using link2sd.
it will work better

Possible solution
- Turn off the phone
- Turn the phone back
- Enter Link2SD
- Run menu option "Restart" to Link2SD
The problem is because during phone startup, can not mount the second unit of the SD. It does later. Making quick restart of Link2SD des only the user interface is restarted and will work correctly.
For more details visit "h t t p : / / w w w . l i n k 2 s d . i n f o / f a q "
"Q. Every time the phone boots have a message" mount warning "quick and i must reboot the phone in order to see my linked apps, Which Could be the cause?
Some roms (for example new Samsung Gingerbread ROMs) do not have any install-recovery.sh and init.d scripts 2nd partition to mount at boot.
THEREFORE Link2SD mounts the 2nd partition after mounting system finishes and you need to perform "Quick reboot" after each "real boot".
This problem has been fixed starting from version 1.9.11. If you still experiment esta problem, Please install latest version and run "Recreate mount scripts" from the menu Within Link2SD. "

Link2sd mount script error fix.

Hi everyone. This is my first thread and i aint any dev. Link2sd is the peoperty of its owner and i am here with just a small fix which is faced by many.
This is a fix to the MOUNT SCRIPT ERROR that is faced by many Link2sd users.
The error is faced while creating mount script, a message pops up [SIZE="5]""mount: mounting /dev/block/vold/179:2 on /data/sdext2 failed: device or resource busy"" [/SIZE][/B] or [B][SIZE="5"]""mount: mounting /dev/block/vold/179:2 on /data/sdext2 failed: nos uch directory found""[/SIZE]
If you too are facing this problem then here is the fix. The fix wont brick your phone or damage it and result is guranteed. Please follow the below steps.
Before Proceeding further Keep in mind the requirements:-
1. Rooted device
2. Partitioned memory card (First partition to be used for media is to be in Fat32 format and 2nd partition to be used as secondary internal storage is to be in ext4 format (or ext2,ext3 but i prefer ext4) (Refer to any tutorials of partitioning a memory card available on the internet. I prefer to use Minitool partition wizard in a pc.
STEPS
1. Install Link2sd (From market)
2. Install App2sd (from market)
3.Convert Link2sd into System app.
This can be done by installing any app from the market which converts user app into system app. Or follow this steps A) Go to /data/app/com.bauk.Link2SD-1 B)Copy base.apk C) Go to /system/app D)paste the apk E) Rename it to com.bauk.Link2sd-1.apk (Do not create any folder) (You will need a file explorer with root access such as root explorer or es explorer)
4.Restart your phone.
5.Now open App2sd
6. Select Link application (or something like that option)
7. It will ask for mounting scripts. A pop up will occur with options to select.
8. Select the format of the 2nd partition (Ext2,Ext3 or Ext4 preferably) and method is to be selected "Normal" (If available)
9. Click on apply.
10. Restart your phone
11. Open link2sd and click the 3 dots in the top right corner and click on Storage info. If Sd card 2nd partition shows the size then you are good to go.
12. Uninstall app2sd.
13. Done
14. Enjoy
Note:- Name of apps mentioned above such as Link2sd, App2sd, Minitool partition wizard, Root explorer, Es file manager are not my creation and are property of their respective owner.
Thank you

Well... I'll try it out later. Thank you so much for this solution. Hope this works.

Hi, there are several Apps2SD apps on PlayStore....... Which one is the one to use ?
Thx
UPDATE : Well, the answer to my "Link2SD issue" is : Apps2SD Pro ( note the "s" after App, there are many App2SD apps out there....... so it's " Apps2SD Pro"
With this app I could partition and format my sdcard, create the mount script and move most system and user apps to the sdcard. However, the developer does not recommend moving any "Google apps" to the sdcard ( I moved Google Drive before I read this and it works fine. Just be careful ! Also, the Pro version does not have ad's and has many, many additional features and this app is updated frequently.
Now I am happy !

tried everithing with this A2107A-H and nothing works my mount path is /dev/block/platform/mtk-sd.1/mmcblk1p2

if i do the same thing what u say everything is ok with partition but it still not shows the storage on storage info and if i try to move to sd card it gives me a java error i restored 3 times my phone and trying 2 days to get it work but it not works im using galaxy s8 plus with nougat and my memory card is exfat im converting it to fat32 and creating an ext2 partition but IT NOT WORKS
NO ONE HAVES A GOOD METHOD FOR THIS PLS SOME ONE SAY ME HOW TO USE THIS APP!?!?!?!?!?!?!?

Thank you very much....!!!
I just tried it and for the moment it works ... we will see how it evolves with the passing of days .... and several "intentional" reboots (verify that the script is not lost).
Again thank you very much, I looked for lost the link2sd on android 7.
Greetings.
This is a Google translation.

Mount Script Cannot be Created
I can't find com.bauk.Link2SD-1 anywhere with ES Explorer nor with the file manager. Tried after installing Link2SD several times still no result.

I used Samsung Galaxy Note 3 N9005 with Resurrection Remix Nougat v5.8.3 with Magisk v12.0 and Dual Boot Patcher.
I had the same problem with Link2SD, got the same error.
The Link2SD developer suggested me to upgrade to Magisk v16.0. I also upgraded to Resurrection Remix Nougat v5.8.5.
This solved the problem with Link2SD at least in my case.

I used to have SM-N9005 but I lost it so for something different , got a moto g4 plus.
I have Magisk v16.0 and lastest RR Nougat.
I was able to get Link2sd to recognize the partition but best I can get is the link to sd function, will not move any apps to sd.
Was wondering if that is just the same as integrating the Ext4 partition as internal?.
Do I need bother with Link2SD if it will not move the apps?.
