[Q] How to remount /sdcard to my ACTUAL SD card?

view story

http://forum.xda-developers.com – I have a SD card installed in my i9500. As you know, i9500 has 16GB built-in RAM, and I found that /sdcard (also /mnt/sdcard) is mounted to internal storage(seems /storage/sdcard0), external SD card is located in /storage/extSdCard ( /mnt/sdcard mounted to here). But some old apps don't support customizing download destination, and most downloaded files went to the internal storage. Also there's some game saves in external SD, but they won't be detected:mad:. How I can fix that? ps: Sorry for my bad English:silly: (HowTos)
