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 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).

Nevermind, I thought it was a data2sd type thing, not just an SD swap. This is very nice! I prefer everything to be on my external card!

I use GL to SD for that. I think the mod is a great idea, but after seeing so many non-readers, surely some Rom flashers will format the wrong partition and bring their blame to the devs...sad really.

What I would like to see is a mod that brings back android 2.x "move app to SD" functionality.

Thanks man! Been wanting this since day 1 and almost started regretting getting a 16gb S3.

Downloading now and will be testing out in my FAT32 64gb sdcard on Synergy 1.7.

EDIT: should have investigated further about what this is doing.

Note that if you want to delete, you must use a ROOT Explorer, and Enable Both Root and Mounting of System to delete the file.

Sent from my Rooted, Synergized (1.7) and now unlocked bootloader VZW S3!

I flashed this at the same when flashing Bean's latest and greatest. So now I see the SDcard and EXTSDcard show the same files and the same size. How can I browse the Internal SD? It does not appear when I plug it in my computer or when browsing using Root Explorer or Astro

Might be not compatible with Bean's. That happens when the script isn't working correctly, you should see two different sizes.

    I really liked the idea of having the 16gb on the phone, than adding the 32gb as extra storage, but i know we can't install programs to the ext sd, but with your program it should work. But what happens to that internal sd? Or does it just make the whole system work on the 32gb of the card?

    exactly, your internal becomes sd, sd becomes internal.

    I don't want to make a flame and I have read the credits but.... This is exactly my mod with a small check if sd is in.

    Op never asked me if he can make this thread. My mod is free do download but.. I don't think is a good behavior to take it, repack it, make a small modification and change the name.

    Please op, revert the name to the original one and link my thread for native support. This thread can be used for specific support for this specific version of gs3 not for other things. Since this is exactly my mod I don't confusion... We can name it extsd2internalsd for Verizon gs3 but I want it's clear that is a simple port with small hack (from you of course! And all credits for his are yours don't worry...).

    Thanks for attention guys!
