Cool HACK: swap your external SD card and your usb storage!

Tired of that small 5gb usb storage? Here is my hack to swap your external SD card with the USB storage!
This is usefull especially if you use GPS apps that download maps or games that download big data files! I got the idea and studied several hacks for the galaxy 1900 so partial credit goes to whoever made those hacks.

DISCLAIMER : I have only tested this on the 4.0 U.S version running 2.3.5 and am not responsible for a brick (although it seems impossible to brick your phone while messing with this file).

So basically start by going to /system/etc using root explorer or similar (yes, you need root). Once there backup the vold.fstab file to somewhere ON ROOT (I put it in /data/app/)! This is important so you can access it if you need to restore it (also make sure root explorer is installed on device memory, not SD card). Now take my modified vold.fstab and replace the original in /system/etc. If all goes right after you reboot your device, USB storage should now be your SD card and vise versa! Be aware any apps on your USB storage will now have to be transfered using a PC, move the .android_secure folder to your SD card. Hope it works!

Well it's now 152 views of the message, but 0 views of the attached file, called void.zip. Perhaps some are concerned about the file name.

Many more are probably like me. I just wanted to understand the message title. I don't have the hardware, and am unlikely to buy it.

So there you go...some feedback.

Steve

I have one but I haven't run into any space constraints yet so... yeah. I haven't rooted my player yet either - still looking for an excuse.

(I am so going to have my geek card revoked for admitting this)

Well, thanks for the feedback! I just found it usefull for downloading large GPS maps without being worried about running out of room (I was already down to 300mb), I had a 32gb card, so I figured why not?
I just wanted to share my work, so this is here if anyone ever needs it.
Personally I would do this first thing when you get your player so you don't have to move a bunch of files.

I've had an Optimus phone for a year with a 16gb card, it's only got 8gb on it, and 5gb of that is music. My plan with the SGP is to use my Google Music account and not put much music on my actual player. I'll probably add an 8gb card, but I can see using up the 5gb internal (I wouldn't add more than "Texas" in maps).

I love the fact that Android really is just Linux lite.

And just like Linux, Android has a great community.

Cheers!

Ran into a potential problem that has the potential to create a real problem although, if you are careful, it won't. However, the risk factor made me decide to revert pending much more research.

The problem is if you pull the SD card, you also lose access to internal memory, even if you reboot. That is because it gets mounted as a sub-folder of the external memory card, so essentially, it can't exist by itself. Which would apply if your memory card got fragged at some point.

What needs to happen is that both memory storages need to have their own separate mount point in the MNT folder and I don't know if this is not possible in Android or if it is just undocumented.

What is really needed is an app mover that can offer all memory locations to APPS2SD and let you chose where to move things. I've asked the developer of ROM Toolbox Pro and he has said he will look into it.
