[Solved] SD internal to SD external Swap

Required

ROOT

i installed FX explore (free)

and installed the FX explore root addon also free

You must have root to edit the etc/vold.fstab file ok

all you have to do is edit the etc/vold.fstab file and swap the items marked in red ok then save and reset the iconia with a pin next to power button

when it reboots you will have the external sdcard as the main internal memory and the old internal memory will be shown as the new external sdcard this gives you a internal memory upto 32 gig

the guide..

gain root

install fx explorer and root addon

run fx explorer

when it opens click on the System(root) icon

a popup will ask to confirm root access click ok

open the folder etc

scroll to find file volt.fstab

at the bottom you will see menu items file , view , Tools , windows, click on tools item

select the option mount read-write

on the popup tick i understand the risk and then ok

tap on vold.fstab and a open with box pops up select text editor

look at the text and you will see 2 lines that do not start with a #

those are the 2 lines you need to edit

only 4 edits are required ok

on the first line to edit swap the first 2 0s to 1s

on the 2nd line to edit swap the first 2 1s to 0s

check below to see what it should look like and make sure yours looks the same

then after you have edited it select the menu item file and hit save

reboot your iconia and enjoy all that extra space to install crap to :)

this is what it looks like BEFORE the edit

dev_mount sdcard /storage/sdcard0 emmc@fat /devices/platform/goldfish_mmc.0 /devices/platform/mtk-sd.0/mmc_host

dev_mount sdcard2 /storage/sdcard1 auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-sd.1/mmc_host

this is what it looks like AFTER the edit

dev_mount sdcard /storage/sdcard1 emmc@fat /devices/platform/goldfish_mmc.1 /devices/platform/mtk-sd.0/mmc_host

dev_mount sdcard2 /storage/sdcard0 auto /devices/platform/goldfish_mmc.0 /devices/platform/mtk-sd.1/mmc_host

below is my edited file ok

notes

if you do this and then remove the sdcard the iconia will still boot but will have no internal sdcard as the original internal sd will still be set as external sd.

also any apps you have installed on the sd card you have removed will still show up on the iconia desktop but if you click to run one it will say NOT INSTALLED

just reinsert the sdcard and all will work . the reason im saying this is i have 2 32 gig sdcards and have the desktop setup in folders so i can switch sdcards and run apps

that are on the current inserted sdcard this gives me almost unlimited storage .
