[Q] How do I change sdcard location mapping? topic

I installed a custom rom on my phone and now my sdcard mapping is backwards with the internal memory mapped as sdcard0 and the externall sd card mapped as sdcard1. Now I need to change these back to the way they should be as all apps are being installed to the internal storage and not the external sd card. I was told that changing a couple of lines in the vold.fstab file does this but it still isn't working correctly as I am only getting the option to move apps to internal memory or phone memory, not sd card. I have the default install location set to sd card but it is actually the internal memory that is being used.

Sorry if this sounds confusing :o
