[HOWTO] Change CM7 Internal SD Location To Stock

So many people have been wondering why thier internal sd is mounted in /mnt/emmc and that is because thats cm7 standard.
But what if you have games that have all the data on the internal sd and want to play them?
Well here is how to change it to stock.
Open Root Explorer.
Mount R/W (On Top)
Go to /etc
Open vold.fstab in text editor (Long Press)
Look for these 2 lines:
Code:
# external sd card
#dev_mount sdcard_ext /mnt/sdcard-ext:none:lun1 auto /devices/platform/tegra-sdhci.2/mmc_host/mmc2 /devices/platform/tegra-sdhci.2/mmc_host/mmc1
# internal eMMC
#dev_mount sdcard /mnt/sdcard 18 /devices/platform/tegra-sdhci.3/mmc_host/mmc0
Remove the # in front of them.
Look for these 2 other lines:
Code:
dev_mount sdcard/mnt/sdcard auto /devices/platform/tegra-sdhci.2/mmc_host/mmc2 /devices/platform/tegra-sdhci.2/mmc_host/mmc1
dev_mount emmc /mnt/emmc 18 /devices/platform/tegra-sdhci.3/mmc_host/mmc0
Add # in front of both lines
Should look like:
Code:
# external sd card
dev_mount sdcard_ext /mnt/sdcard-ext:none:lun1 auto /devices/platform/tegra-sdhci.2/mmc_host/mmc2 /devices/platform/tegra-sdhci.2/mmc_host/mmc1
# internal eMMC
dev_mount sdcard /mnt/sdcard 18 /devices/platform/tegra-sdhci.3/mmc_host/mmc0
#dev_mount sdcard/mnt/sdcard auto /devices/platform/tegra-sdhci.2/mmc_host/mmc2 /devices/platform/tegra-sdhci.2/mmc_host/mmc1
#dev_mount emmc /mnt/emmc 18 /devices/platform/tegra-sdhci.3/mmc_host/mmc0
Reboot.
Do the opposite to return back.
You can also just copy the file from other roms like Ninja, Alien, etc.

How do I open it in text editor and edit it?
Edit: nevermind the long press has scroll lol

In RootExplorer make sure you are r/w and long press on it and select open in text editor

Wait in your "what it should look like" you still have # in front of the first two things. Should they be there?

This slept with my wife... But I won't hold you responsible. Thanks for sharing.

Good post, I made this suggestion and had my head bitten off....

I've tried it both ways--editing the file and swapping it in from another ROM (setting permissions and ownership appropriately after the latter)--and the internal "card" is mounted as /sdcard, but the external card doesn't seem to be mounted at all. Is there another obvious step that I'm somehow missing?

Can this Mod be packaged as a CWM file?

The same thing happened to me brother. You're not doing anything wrong. I tried editing the file 30 times and got the same result each time, it's nothing you're doing.

Can we mount internal as SD card and external as sdext?

CM works differently, using the method posted you won't be able to mount the sdcard. You will have to mount one as emmc. If you want to mount the sdcard as emmc, then you need to change:
Code:
dev_mount sdcard_ext /mnt/sdcard-ext:none:lun1 auto /devices/platform/tegra-sdhci.2/mmc_host/mmc2 /devices/platform/tegra-sdhci.2/mmc_host/mmc1
to
Code:
dev_mount emmc /mnt/emmc auto /devices/platform/tegra-sdhci.2/mmc_host/mmc2 /devices/platform/tegra-sdhci.2/mmc_host/mmc1

oooohhhh emmmmmm geeeee.....while running thru the vold.fstab file i figured out how to automatically mount a usb powered device without the use of terminal emulator or a script... (sorry if i'm late with this "finding" lol) but all u have to do is go to "/mnt/" then create a folder named "usbdisk_1.0" and change the permissions to --xrwxr-x then plug in your external hard drive/flash drive and boom!!!
edit: seems u have to create the folder every time you restart the phone :/ anyone knows how to make the folder stay??

Nice find and same here with the folder deleting itself on reboot.
Also to those who managed to get thier internal sdcard in /mnt/sdcard but cant find thier external sd, same happened to me, but if you go into settings , storage you can see it is saying that the external sd is the interal storage and the internal is external storage so if someone could help me figure out how to fix this and properly mount each sdcard, then thanks, until then to use your external sd you need to change it back to cm7 stock and to use the internal sd then change it back to moto stock.

the post above mines that u quoted shows u how to get the external sd card working, but mounted as emmc.

Can someone explain this feature of CM7 to me? From what I gathered, CM7 by default mounts the internal storage to emmc and the external SD card to sdcard. Apps use sdcard for storage, so all the data gets saved to your external SD card in CM7 by default. Can you just copy the folders from your internal card to your external card as a workaround?

[How To] Swap the mounting points on ICS (CM9) for emmc and sdcard.

This is a quick tutorial I want to write up based on a recent experience I've had recently with my micro sd-card. (More info on that below)
This how to shows how to switch between the internal sd card and the external sd cards mounting points (so the external is accessed via /sdcard, and the internal is accessed through /eemc)
The nuts and bolts how to:
0. Perform backups on System, i am not responsible for any damages or boot loops.
1. Download root explorer (or any other file explorer with root privileges)
2. Go to /system/etc, and mount R/W
3. Long press on vold.fstab and select Open With... , select Text Editor
4. You will find a line with sdcard in it a few times, change this section:
dev_mount sdcard /mnt/sdcard
Click to expand...
Click to collapse
To:
dev_mount emmc /mnt/emmc
Click to expand...
Click to collapse
5. Do the same thing with the emmc section:
dev_mount emmc /mnt/emmc
Click to expand...
Click to collapse
To:
dev_mount sdcard /mnt/sdcard
Click to expand...
Click to collapse
6. But you just flipped the first section around? Yes I did, this changes the mounting points. But not the original location of where it is being mounted......
7. Please don't change anything else in this file....
8. Reboot, enjoy!
I had to do this hax because the current nightly of CM9 doesn't support there being no external sd card, and mine got corrupt (eep!), it then continued to mount the internal sd card location to emmc instead (wtf?). So i did this quick hax so i could take pictures with the stock camera and use several applications which just default to the internal sdcard (and doesn't allow changing that).
Hope that helps some random Googlers......
Note: This has only been tested on CM9 Nightly apr-9th on SGSII, but i see no reason for this not work across all ROMs and devices( with ICS, the emmc thing wasn't on GB and below i don't think) as long as you don't do anything as foolish as change more than the lines specified above.
An example of a swapped file is (DO NOT COPY AND PASTE THIS, YOU PROBABLY WONT BE ABLE TO BOOT):
# internal sdcard
dev_mount emmc /mnt/emmc 11 /devices/platform/dw_mmc/mmc_host/mmc0/mmc0 encryptable_
# external sdcard
dev_mount sdcard /mnt/sdcard auto /devices/platform/s3c-sdhci.2/mmc_host/mmc1
Click to expand...
Click to collapse
Please note that the latest CM9 nightlies lets you do this from the system menu! This was written pre that advancement. This is for the curious and other ROMs/phones.

Is it possible to use something in the lines of:
dev_mount emmc /mnt/external_sd ? To just bind the external sd to the stock location?

If I understood your question right, that's the default behavior in CM7/9 so you don't need to change anything.
(internal gets mounted as /sdcard and external as /emmc. At least that's how it always behaved on my device -takes a bit of getting used to but it's manageable once you know the trick)
edit : aw sawry, mistook /mnt/external_sd for /mnt/sdcard. But it changes nothing besides the name of the mountpoint, easily adjustable.. Although why you would want to have it named like that is beyond me, it makes for more keys to hit when typing it... xD

Its the same technique....
So remember this:
Format: dev_mount <label> <mount_point> <part> <sysfs_path1...>
Click to expand...
Click to collapse
So <label> doesn't really matter, but we may as well keep it sane (and have it the same name as the mount point)! And <mount_point> is where its mounted. Make sure the folder exists first though! leave <part> and <sysfs_path*> alone and it will work correctly.
So if you were to create a folder /mnt/hammertime , then make a line look something like this (taken from my example in first post)
dev_mount hammertime /mnt/hammertime auto /devices/platform/s3c-sdhci.2/mmc_host/mmc1
Click to expand...
Click to collapse
That will work correctly.
Hope that helps!

I didn't think so either, but i had the problem, hoped it was like its Linux cousin and searched for fstab, i found it. Swapped the mounting destinations around. And voila, done.....

Swapped but CWM Recovery still the same
Hi, first of all nice guide you did here.
Here's the thing: somehow somewhere by flashing nightlies i ended up
with /sdcard being treated as my external SD while /emmc was for internal.
So I wanted to fix that and using your guide although the other way around
I was able to make it as such: /sdcard = internal storage; /emmc = external storage.
ALL IS GOOD however when i booted to CWM recovery:
CWM still mounts my internal storage as /emmc.
SO in recovery internal storage = /emmc while when in CM9 internal storage = /sdcard
Is there anyway i can change CWM so that internal storage = /sdcard? to be more uniform and not confusing

Yeah CWM doesn't read the /system stuff, it has its own partition....
I've got no idea sorry, but its just a little inconvenient in CWM thats all.... But im sure you can check it out... Just search for fstab when you figure out how to explore the recovery partition (I've got no idea , short of modifying a flashable zip first and rekeying it.)

Forgot to post back with my results, Got HFS & AOKP to see the changes, however something broke when I did a PC mount. After playing with the lines "Experimentation" if you will, I ended up needing to rebuild my partitions! No fault of yours, I just wanted to see if I can have that functionality through the whole phones usage and features eg. mounting to the PC.
Thanks for the guide though, I'm seeing now that some devs are including the option to use the internal memory via a menu select, I wonder how there implementing that.

Probably something very similar but programmatically instead of the haxy file editing method I'm noting to use .
PC mounting is working as per normal for me here though...... (I don't have an external card right now so that may be a variable)

That it is, cause I can see my internal, but it doesn't mount the external.

Purpose
What is the purpose of this? Does it mount the EMMC so that the system thinks EMMC is actually an external sd card?
I am trying to figure out if there is a way to make the above mentioned happen. Or is there a way to re-partition it so that EMMC is used as system memory... or maybe even both? It seems that since ICS better integrates with on board memory, there would be a way to better integrate the internal memory of older devices with the system.

This guide shows you how to "flip" the points. Several ROMs have it differently preconfigured. But if this is your current situation:
Code:
Emmc: External SD Card
SDcard: Internal SD Card
It will make it:
Code:
Emmc: Internal SD Card
SDcard: External SD Card
And vice versa obviously (its a flip).
This guide will do what your wishing it to do.
The folders sdcard and emmc (or there /mnt varient more closely) are just soft links, meaning they don't really exist, but just point to another location. We can modify which folder they are linked to in the fstab.void file.

so to make emmc to external_sd i change "dev_mount emmc /mnt/external_sd"?

Worked great on a Captivate running AOKP-36 right after a wipe data/factory.

lol you need no guide on cm9
you can switch them in storage settings by a simple checkbox
its mentioned in team hacksung's FAQ

Im on CM9. Can someone post the code so i can just do a simple copy and paste? I wanna switch emmc to external_sd
(there is no storage settings simple checkbox for me)

Never use a copy and paste for the file in this operation. You only need to modify partially two lines (which you can copy and paste from the OP).
Your just swapping two words around really. Its fairly easy, just follow the steps and it will work, it looks daunting at first if your not used to doing this sort of thing, but its fairly easy.

IDEA: Hacking internal/external sdcard mount paths

Hello.
I'm using the latest aurora and I'd like to discuss an idea I had.
Since the U8800 has plenty internal memory and it's quite fast comparing to an average sd card, it'd be great if we could use the internal memory for the tasks that need "speed" instead of "space".
Running apps from the sd card is the perfect example!
So the idea would be, while keeping the external sdcard mounted on /mnt/sdcard, having /mnt/sdcard/Android/data, for instance, point to the «internal sdcard path»/Android/data.
What do you think would be the best solution:
- hacking the mount points?
- using links?
- other solution?
Any developer or filesystem savvy user can point the advantages or dangers of using this solution?
- e.g.: the system or some apps may check if the external sd-card is mounted before trying to read/write to /mnt/sdcard/Android/data... that would mean the system/those apss may think that path isn't reachable with the ext-sdcard unmounted, altough they can be read.
Suggestions? Rants? Ideas?
Regards!

I have wondered if the /data/app or maybe the whole /data partition could be mounted in the internal storage partition. That would give 2gb space for apps and associated files instead of 3-400 ish and would mean no need to move apps to sd card which would mean faster loads at startup due to internal memory being faster.

Well this is known for a while now . Quoted from my thread here:
vold.fstab - CHANGE THE DEFAULT SDCARD: -thanks to julle131
There is this file named vold.fstab at your /system/etc/ folder, which controls which of your sdcards (Internal/External) will be mounted when you connect your phone to the PC. The last 2 lines are the only that matter. These are the two possibilities:
EXTERNAL SDCARD MOUNTED (DEFAULT):
dev_mount sdcard /mnt/sdcard auto /devices/platform/msm_sdcc.4/mmc_host
dev_mount emmc /mnt/sdcard1 14 /devices/platform/msm_sdcc.2/mmc_host
INTERNAL SDCARD MOUNTED:
dev_mount sdcard /mnt/sdcard 14 /devices/platform/msm_sdcc.2/mmc_host
dev_mount emmc /mnt/sdcard1 auto /devices/platform/msm_sdcc.4/mmc_host
change them as you wish with a root explorer or before flashing.

Make this change and every app will use the internal sdcard. Gallery works ok with images to external sdcard, it just might take a while for the first refresh. But I don't know if you'll notice any difference in terms of speed....

That's not what he talked, I think. He said that the apparel would be installed on the external sd card, but the data would be moved to the internal one. And we have speed, but the main card would be the external one.
I think its a great idea if I understood it right!

Oh I see! Sorry about that. As far as I know apps are not choosing were to put their data. They just say to the OS "I want these things to be at the sdcard" and the OS puts them at the correct place. So you can't "hack" the app to "see" at somewhere else. On the other hand the OS initialises on boot which card is the primary and which is the secondary. So my knowledge stops there and I can't imagine a way to make this separation between app data and the rest...
I hope for someone else's help!

Maybe this cannot be done, because I think that the mapping of the partitions and mounts comes from the bootloader, but there is already the solution of resizing the data partition using the space of internal storage.

That's a great idea!
I almost don't use the so called "internal sd card", therefor I have 2GB of fast empty space being wasted.
Why not simply mounting the internal sd-card partition in the data folder and the data partition on the internal sd card folder?
I only use the internal sd card to hold ringtones and other small stuff that I need to be in accessible 100% of the time, so a few hundred MB are enough!
Me gusta!
Every ROM flashes it's own fstab, right?
So all we'd need to do would be, editing the fstab before flashing it.
-----------------
Regarding the my first idea... I don't think one can simply mount a path on another path. We'd need a "virtual" device pointing to /mnt/sdcard-internal/data/ then mount that virtual device on /mnt/sdcard-external/data/.
My knowledge of unix mount/filesystems is not much more than what's explained here: https://help.ubuntu.com/community/Mount
OK, just found this:
http://askubuntu.com/questions/11079/mount-a-directory-to-look-like-a-drive
there is a FUSE filesystem named bindfs that probably does exactly what you want. For example the following:
bindfs -n /media/USB-HDD-01/ISO/ /home/johnc/ISO-images
Click to expand...
Click to collapse
would result in ISO-images to show up as a mounted filesystem in the Places sidepanel in Nautilus. The -n is required because otherwise bindfs tries to use the allow_other FUSE option, which by default is not allowed for regular users (if you use bindfs in /etc/fstab this is not a problem).
The first directory you give is the existing one, the second directory you give is an empty directory under which the contents of the existing one will appear.
Click to expand...
Click to collapse
So, bindfs depends on FUSE... and there's a port of fuse to android: https://github.com/seth-hg/fuse-android but looking at the README I get the feeling that it's not really working. The last step would be having a kernel with FUSE support... and regarding that, I have no idea, how easy it is to get a kernel like that for our U8800 :\

Finding such a solution to expand the DATA partition indirectly would be great!
I used to apply genokolar's custom partition method as "1.2G DATA + 1.46G INTERNAL SD" before, but i found out that it has some issues with Official 2.3 Roms. One of them -the most important IMHO- is the BOOTLOOP problem occurring in some specific situations!!!
See the details in my post here:
http://forum.xda-developers.com/showpost.php?p=25853141&postcount=134
(Seems that I don't encounter the bootloops on Custom Roms, but i'm not %100 sure and never will be )
So i unfortunately gave up using it, and revert to the stock partition .
I will be grateful to the one who will find a better and reliable solution. Hope to see it soon...

I still have to gather more information on the official update "modus operandi".
My goal is to simply reformat both partitions and then swap their mount points.
If the official update formats the partitions before applying the flashing official ROM files, then partitioning changes shouldn't cause any failure on the official update.
But like I said, I'm still yet to confirm that info.
Gen's idea was great (I learned a lot just by looking at his scripts) but resizing partitions has its dangers.
Since "no one" really uses the internal memory, why not simply exchange its room with /data, right?

This would be awesome! I would love to have 2gb for apps, instead of cluttering my phone.. plus the 2gb of internal storage are just a waste for me.. I never use them.. so this would be great!

[Guide] Enabled Link2SD and later swap

Hi all Users, I show here how you set up your microSD for Link2SD. This How to is from einstein.frat but I got his permission to offer this guide for the S3 mini. Thanks einstein.
Important!
From now on your SDCARD should not be Unmounted or ejected when phone is on.
Only eject SDCARD if phone is off!
Requirements:
- a rooted rom
- init.d support
- MiniPartitionWizard (HomeEdition)
- ext4 partition on your microSD
- swap partition on your microSD
Info:
I recommend to create the swap partition because I want to fix the swap script from the Desire C device.
Do I need to Backup my SDCARD contents?
Not needed, but if you want you can, it doesn't erase your sdcard data unless you did something wrong.
01/ This Guide is for your windows machine.
02/ Unmount your microSD card on phone eject it and insert your microSD with a card reader in your PC.
03/ Install the MiniPartitionWizard (HomeEdition).
04/ Run the MiniPartitionWizard.
05/ Look for your SD card along the bottom and identify your FAT32 Partition.
Now we start:
06/ Right click on it and choose "Move/Resize Partition".
07/ Use the down arrow in the middle field "Partition Size:" To change the value and consequently the value of the "Free Space". After: field as well until you have created around 2307 MB of free space.
08/ Click "OK".
09/ Identify the new unallocated space on the drive map.
10/ Right click on it and choose "Create".
11/ When you get the warning about the partition not being able to be used in Windows click "Yes" to continue.
12/ Choose "Ext4" for partition type. Primary, Resize to 2000 MB.
13/Right click on empty 300 MB left, Create: Linux swap partition, set as Primary.
14/ Make sure it is all primary not a logical partition.
15/ Name it if you want.
16/ Click "OK" to continue.
17/ Click the BIG "Apply" button in the top left of the window.
18/ Choose "Yes" to continue from the pop up.
19/ The tool will start to work.
If it is successful, congratulations, the first section is completed!
Now to the second section:
1/ Eject and place your microSD card back into your phone.
2/ Install Link2SD from the Android Market.
3/ Run it.
4/ On first run it will ask you the type of partition your second SD card partition is. Choose Ext4 depending on which you made it.
5/ Follow the directions to reboot your phone.
Yes, Link2SD is working on your device!
1.choose the funnel and choose User.
2.choose multi select and select apps to to be moved to sd-ext and choose actions then create link choose all 3 checkbox.
At this point I recommend you Menu click and go to Settings and choose "Autolink" to automatically link programs (.APK), dalvik cache files (.DEX) and library files (libs) to your SD Card 2'nd partition when a new program is installed.
Now for some strategy!
Posted by einstein.:
You say, "I've got all this external space! Why bother putting any programs on the internal space?"
Well...SPEED MAN! SPEED!
I keep Launchers, Widgets, Background processes like Titanium Backup, etc, on the internal as space allows to allow for speed when booting. The internal memory is faster than your SD card and keeping these programs here helps a lot in speeding up your boot time. This is an option with Link2SD that you DON'T have with Data2SD or Data2Whatever!
You can also keep commonly accessed programs like Tapatalk for example, on this internal fast memory.
You can also mass move by multi selecting, several programs to and from either internal, SD card, or SD card second partition. Ideal for your initial move to your new second partition of your apps pre-installed prior to link2sd.

So it should have been first and if I have fixed the swap script then I update this thread but swap is not essential to life (my opinion) because it is only activated when the RAM is full!
For question (problems) I`ll help and I would be happy when you press the thanks button. I wish you much fun with Link2SD. :fingers-crossed:
Thankslist:
einstein.frat, faria

I understand I expands the internal memory of your phone with a two GB SD card?
And you can create a partition instead of 2 GB to 25 GB or more to display more data or do the sd card with ext4 filesystem?
What you need to do to work with the remaining games on SD memory card in FAT file system.
Help please. Thanks in advance.
P.S Sorry for my english. I used google translate.:good:

Hi, sorry my English is not so good for explanations but I try it now and edit the post. One moment please.
Greeting
Edit:
So the size of the ext4 partition which you mess on your microSD is depending on the size of your microSD. You can not create on a 2gb microSD a 2gb ext4, why? You have not more space on your FAT32 (microSD) partition for your personal files. I do not know how big is your memory card, at a 2gb you can also create a 1gb ext4 partition for your apps, or even 800MB. That does not matter but you can not make from a 2gb memory card a 20gb. That is not the function of Link2SD. If you have only a 2gb microSD then create a 1gb ext4 partition and is your ext4 full, sometime, then move your apps back to your device. It is the best when you have at least a 4GB microSD. Better is 8gb, 16gb. You can do with much more with Link2SD as APPS2SD or Data2SD. Believe me I've tried many things over the last 9-11 months (HTC, Moto +++), and I'm glad I have also the good dev DSCPLX (einstein.) in the XDA. For questions, write quietly. If I can help I will do it. I wish a nice day.

Thx for answer.
Mutual, you too :fingers-crossed:
My external SD card with a capacity of 32 GB. So if I understand correctly I can create additional internal SD memory card up to 20 GB + + instead of 2 GB that is completely have my external card at an ext4 partition.

Hi, slowly ... No, you create not a new internal SD. The ext4 format is from linux and for your android device is the ext4 and swap partition of your microSD invisible. On a Linux system, these partitions they are visible but not on a windows machine.
I still do not understand quite what you have always with 20gb? Under Linux, it is so that there is only one guarantee for ext4 partitions to 2GB. So I know the statement.
You have a 32gb microSD and then create a ext4 of 2048MB and that's just enough. A smartphone is not a Alienware machine, lol. :fingers-crossed: Fun!
You can use the ext4 partition also test with a 2.5 gb ext4 partition but I can not guarantee for the permanent functionality.
Regards leather.face
PS: I hope you understand my english, lol.

For those of you with questions, look up the old A2EXT process for the G1/MyTouch 3G. This is the same thing.

Hi, thanks for your info but Apps2SD have not the same mode of action as Link2SD, why? In Link2SD you can always move as you want ... You can move 1 app or 2 apps or 30 apps to your ext partition or move the apps individually back to your device. This is the sense from Link2SD and at Apps2SD need to move all the apps mandatory. I've worked in my career with Link2SD, Apps2SD and Data2SD but Link2SD has the best mode of action for a phone. Link2SD is faster then Apps2SD and Data2SD.

A2SD in Android has two meanings:
1) A2EXT: This is the method outlined. As I previously posted, Google it and read up on some Android history.
2) A2FAT: This was introduced with Eclair.

should i have this init.d ? where to download it and where to put it on the momery...
please help.

Hey leather.face!

i have read this threat and your other about the init.d support and scripts made/collected by you (i can't post in the other threat due to permissions)

I'm confused as well. This guy created a 2GB partition but he doesn't explain why it can or can't be larger than that. I use Linux at home and you can have an ext4 partition as large as you'd like it

So. 2 GB is used for apps. What happens to the rest of my 8GB SD card.

Hello,
first of all thanks for this guide. I followed it perfectly, but when I run Link2SD, after having configured the Ext4 parameter, if I click on the location parameter I then receive this error message :
"App2SD is not supported by your device. Because your device has a primary external storage which is emulated from the internal storage. You can link the app in order to move its files to your SD card."
All my apps are linked to the SD card, but when I try to move them to the SD Card, I have again the error message saying "App2SD is not supported by your device etc ...".
I have a stock rooted ROM, I installed the init.d feature, I installed Busybox, my SD Card is well prepared (a 12 Gigs partition in FAT32, then an Ext4 partition of 2000 Mb, then a Swap partition of 340 Mb).
So I don't understand what's wrong on my device.
Is this working as expected ? I mean is it impossible on a S3 Mini to move apps to the SD Card ? Only linking is possible ?
Is there custom ROM which would allow us to move apps to SD Card ?
Thanks !

Hello everybody.
Thanks to y'all
I have done this before, when I was using Galaxy Ace §5830. The guide is a treasure but I experienced certain things like the apps being linked and not moved. So later on, I couldn't install more apps and big games.
***********Questions*********
Now am on Galaxy S3mini 4.1 2 Jelly bean, and I'll love to play big games on the device. 1. I want to know if doing this will help me move the game data (which is usually large) to sd card.
2. I want to know the best way of doing this for Galaxy S3mini I8190
And (easy way) how to do it. ( possible suggestions on partitioning 32Gig sd card)
3.I want to thank all you once again for listening to a person like me.
4. I'm waiting for the first reply starting from now.

For games with obb-files in sdcard/Android/obb, you can move them to external sd and mount it with foldermount
Saves alot of space.

First of all Thank you for this wonderful guide. i have done everything and linked my apps to sd. my question is can my sdcard be reverted to how it was before? Why?
well because i can't use my phone as an MTP when i connect the usb cable. any solution to this that i'm missing? Thanks in advance.

So quick question, I have a 64 gig card, I created a 16 gig ext2 partition, can link2sd even read the space after 2 gigs?
I need to get this working

[Q] Rooted to Liquid Smooth and can't move apps ?

Hello guys and gals!
I've recently flashed my first rom on to my SG4 and when I got it from sprint with the stock rom (4.2.2 , MF9) it would allow me to move apps to my 64gb10 class sd card but now it won't even give me the option with the new rom, the rom is fantastic no glitches or lag and as it was restoring my internal storage was full in a few minutes and when I tried to move my apps there was no button (option) at all for it.
I've tried to swap external with internal memory no luck so far :[
Please help any help would do. I'm new to the fourms and i have tried searching as far as i can get no one else is posting same post as mine. I'm a noob on the tech stuff not super smart or too dumb average. Also if i do a factory rest on my rooted liquid smooth rom will it get bricked or will it go back to liquid smooth, as it was on first time install.

Yupp, exactly what he said. You are no longer on TouchWiz software so there is no apps 2 SD unless AOSP adds it in. There are apps on the Play Store I believe though that can do this.
