there is a post on xda forums with full instructions
So if I get this correct, and it does sound logical, all I need to do is edit the file so tht the extsd below is the sdcard nd vice versa. Then the sdcard will point to the external card...
*** GUYS DONT DO THIS UNLESS YOU KNOW WHAT YOU ARE DOING, AS NOT SURE MYSELF *** - Code: Select all
# Mounts the first usable partition of the specified device
#/devices/platform/awsmc.3/mmc_host for sdio
dev_mount sdcard /mnt/sdcard auto /devices/virtual/block/nandi
dev_mount extsd /mnt/extsd auto /devices/platform/sunxi-mmc.1/mmc_host /devices/platform/sunxi-mmc.0/mmc_host
DO NOT DO THIS UNTIL SOME ONE WITH REAL TECHNICAL ABILITIES SAYS HOW IT CAN BE DONE.
Looks like someone tried my simple suggested change with dire consequences....

You do this at your own peril.............
there is no peril imo,it works absolutely fine,as above post I have tried it on cyanogen mod the only thing it does do is break updateme for some reason -have no idea why though
it is easiest by far on a clean install with minimal apps installed to the flash memory as you will need to duplicate all apps from flash to the microsd card first
I did it with around a gb of data on the internal flash & using a file manager it took the best part of 2 hours to copy data to the microsd
will run through the steps I did
download file manager (rhythm software) from the play store
open it ,open settings (3 dots bottom left of screen)
tick the root explorer box & the mount system folders box
go up through the directories until the up box turns grey & you will be in the system folders area
open system directory,then etc directory
long press the vold.fstab file
select copy,then go up a directory & press paste
go back to etc directory,long press the vold.fastab file again & select rename,rename to something like vold.fstabbak or similar (it doesnt really matter what)
go up a directory again (to where you copied the file) short press it,open as text with text editor
change the 2 lines to
dev_mount sdcard /mnt/extsd auto /devices/virtual/block/nandi
dev_mount extsd /mnt/sdcard auto /devices/platform/sunxi-mmc.1/mmc_host /devices/platform/sunxi-mmc.0/mmc_host
press escape/back button (next to volume on top of tab) twice to save
long press the file again,select copy
go back to the etc folder & press paste
,the above copy/rename steps above are
1. to give you a backup file
2.because you cannot edit the vold.fastab file while it is in the system directory for some reason (I know you can rename it but for some reason it cant be edited until it is outside of the etc folder - at least not in my experience)
you now need to copy all the data from your flash memory to the microsd card,either by using file manager again,or by disabling usb debugging,connecting to pc & using windows.
once done ,reboot the tab,your internal memory should show as whatever size sd card you are using,try a few apps etc,if all seems good you can delete all data from the 8b onboard flash- it is now only good for media files as the microsd card was before
please, though even I consider this safe,make a backup using cmw before doing any of the above - for the sake of 10 minutes its well worth it
