[MOD]App2ExtSD2 [Works for all U.S. Galaxy S3!]

This is a hack that that allows you to swap internal storage with your external SD card so you can increase your app data storage.
All credits go to original i9300 App2ExtSD Hack by mattiadj. I simply hacked it to work with U.S. versions and also I've added code so it will disable this feature when you don't have a microSD card inserted (app storage will default to internal when no microSD card is inserted).
E.g. If you have 16GB internal storage on Galaxy S3, you can install this witih a 64GB microSD card and swap the storage and get 64GB on your app storage instead of 16GB.
Before you can use this, you will need:
1) Rooted Galaxy S3 (SCH-I535/SPH-L710/SGH-T999/SCH-I747) or also Canadian versions too (i747m, etc...etc...)
2) A ROM/kernel with init.d support!
3) I've only tested this with TouchWiz-based ROMs, so it should work on stock ROMs and any TouchWiz-based ROMs, not sure on CM9 or CM10.
4) You must use the FAT32 or EXTFAT zip file below, depending on what format your microSD Card is in! (e.g. if you have a FAT32 microSD card, use FAT32)
To get this working, simply flash the zip files in your CWM Recovery:

If you are on stock ROM or any TouchWiz-based ROMs, you can flash my new HighOnAndroid kernel to get init.d support on your phone here:
http://forum.xda-developers.com/showthread.php?p=30718496
If you do not have init.d support, you can also enable on any rooted phone by using Script Manager, here's a quick tutorial:
I recommend you to FORMAT your microSD card once to get camera working flawless before using this hack!
How to disable this:
If for some reason you are having trouble, simply delete /system/etc/init.d/11extsd2internalsd.
OR
if you leave your microSD card out during boot (then re-insert it after), your phone will work as normal (internal storage used for app data).

Sounds awesome thanks

MAX TO THE RESCUE!!! I've been waiting to see this! Much love Zedo, I always hold it down for you with my signature links! I really hope your going to come back to YouTube one day though. But. in the meantime I'm glad your still putting all of your content out there for us!

Is it best to wipe first, or will this move all the app data from the internal to the external for you?

It is best to do a wipe to start on a clean slate, or you can also copy the contents of your internal to external.
OR, I like using Titanium Backup to backup app and its data then restore after putting in the microSD card.

it works great, thanks for the mod, will report if I find any problem w/ it.

Great work max! I was using stock rooted rom.. Now I need to look for one I like that has int d support.
Thanks for this though appreciate it!

Would it be possible for you to create a Stock kernel with just the init.d supporthe?

My SD card is reporting "vFat" as the type......is that FAT32 or EXTFAT or neither? lol

yes let me see if i can upload it tomorrow

Is there a way to tell what first the sd card is from the phone? Not really sure on what first it is

When I use Camera to take picture, picture are not stored
Anyone else has the same problem, or could you please test the Camera.
I didn't to the clean wipe.

do you have the setting enabled to save all pictures and videos to the external sd card?

This is kickass! Can't wait to get home and format sd.
Zmax...thank you.

I meant format. Sorry about that. Autocorrect got me again.

This is great! I'm curious if this mod sticks if I flash an updated/new rom? Do I need to flash this zip after I flash the rom? Also, what happens if I wipe my phone when I have this mod? Do I need to re flash as well?

[Q] My Rom is Telling me I'm phone is almost full but...

When I look from the perspective my computer I can;t identify where I have fill all 15 GB from?
Could this be a possible error from the Rom its self or is it hidden files that wouldn't be seen by my computer that is causing these kinds of issues?
I have also tried switching to have most my app and information stored on the SD card but nothing seem to be working.
Thanks for any help in advance.

Do you take a lot of pictures and/or video? If you're using a TouchWiz-based ROM, then you can tell the camera app to use the external storage (SD card) instead of local storage.
You can move them over with any file manager app.
Otherwise, I'm not sure. It's possible you have some games installed that simply can't be moved to SD, but that's pretty rare now days.

Nope
I don't really take any pictures nor do I store anything on my phone really.
Here are the screenshots I took of my memory usage.
My SD card is more Full than the internal memory.
I had tried doing a factory reset which did lower the totally memory usage but still had the system memory issue.

Thanks for this suggestion but I tried to down load it and my phone said I didn't have enough storage despite the storage information I had previously posted.

I would go for a fresh, clean install. Backup, wipe all and reflash.

Agreed but I don't know 100% what to do about it.
I have done a wipe but it seems like its always still full which doesn't make sense.
I looked into storage after I installed a 4.2 rom and it said I have 4.2GB from CWM but then I can't find the files to back that up when I look from the computer side.
Any Ideas?

How many nandroid backups have you made?
I'm thinking you got a few you could get rid of.

Lost.dir is for a repair recovery thingy for Mac I think. So basically, you can delete it's content if it's not something you wish to recover.

Ext SD Card Question

Don't mean to sound stupid but ill feel better if I at least ask. I for the first time bought a micro sd card for my phone. Before I start to move files to it id like clarification on a couple of things. If I move my apps to the sd card, what happens when I flash a new rom? Do I have to install all of them again? Are they automatically recognized and installed automatically? Is. There anything I shouldn't move to the sd card? Also can I move TWRP to the sd card? If I can and boot into recovery the phone will know where the program is located? Dont mean to babble but whenever I try something for the first time like this I just like to get as much info before I proceed. Thanks for any help I can get on this.

You can back them up. You have to have the Pro version of titanium backup but you can upload your apps to cloud storage and re download them. I'm not 100% on that because I never restored apps. I could be wrong but you can for sure backup apps before flashing

[Q] can't write to the external sd card (Aosp)

I don't know what the prob is but I was able to write to my sd card this happened like a week ago I was on a 4.4.2 two rom and had no issues with it then I went to an aosp room still no issues then I flashed another aosp rom and that's when I noticed the problem I can read the sd card I can even copy stuff from my external sd card to my internal one no prob but when I try to copy something from my internal to external I get an error message saying read only file system I tried those sdfix apps I tried a couple of them and they all say I'm good I have permissions to write on the sd card but I still can't. Has anyone had this prob or can point me in the right direction any help will be appreciated.

You could also try formatting the SD card, or try a different one if you have a spare

External SD card issue.

I have an external sd card. It needs the fix for kitkat. But can not use the fixes in the market they all need root. How are you guys dealing with this issue.

You just have to deal with it until root is achieved, there is not way that I'm aware of to fix the KitKat SD card changes without root.

I don't get why we have to wait for root. If the phone supports 64gb sd card out the box why is this an issue. People that don't have xda experience will be thinking something is defective. Correct me if I am wrong.

Yea it's truly starting to get annoying. Another thing I noticed is we have no cast to screen ability with chromecast.

Yes I noticed that also. You shouldn't need root to fix that issue. Most people don't root there phones.
