[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 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!

How do you know if your card is exfat or fat32?

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.

If you have a microsd card adapter (i highly recommend having one), plug it into your computer and do right click->properties for windows, others should be similar. Go google it.

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.

Do you guys use more than 16gb of app space??

If you play a lot of games, GTA is like almost 1GB, the real 16GB internal only provides 10GB in reality, meaning if you play more than 10 games like GTA you run out of space real quick.

But I don't use that much space.

I'm not very found of kernels yet, but I'm running synergy ROM r50 does this change my system to a supported kernel?
