The original guide here: [How To] Swapping the internal and external SD cards - ZTE Blade V - MoDaCo on the ZTE vital its basically the same but with a few differences. This mod should be done on a fresh phone. Or at least don't have any apps installed to the SD card. Having apps on the SD card before this mod could cause abnormal behavior and corruption. Its also not a good idea to have large games installed. On my VM supreme your looking for vold.fstab in the /system/etc/ folder. open the file as text and scroll to the bottom and you will find this. PHP: #dev_mount sdcard /storage/sdcard0 auto /devices/platform/msm_sdcc.3/mmc_host #dev_mount sdcard /mnt/sdcard2 auto /devices/platform/msm_sdcc.3/mmc_host dev_mount sdcard /storage/sdcard1 23 /devices/platform/msm_sdcc.1/mmc_host dev_mount sdcard2 /storage/sdcard0 auto /devices/platform/msm_sdcc3/mmc_host In order to swap the cards, you simply change sdcard1 to sdcard0 and sdcard0 to sdcard1 in the last two lines. It will look like this: PHP: #dev_mount sdcard /storage/sdcard0 auto /devices/platform/msm_sdcc.3/mmc_host #dev_mount sdcard /mnt/sdcard2 auto /devices/platform/msm_sdcc.3/mmc_host dev_mount sdcard /storage/sdcard0 23 /devices/platform/msm_sdcc.1/mmc_host dev_mount sdcard2 /storage/sdcard1 auto /devices/platform/msm_sdcc3/mmc_host After done, reboot. Instead of the measly 1.5gb, you now have the space of your external SD card.
