唯科V90D旗舰版如何对调SD卡和USB存储器的方法

novafan

     之前用的是NEO-N01的一台机器，这个机型我参照了http://bbs.ydss.cn/forum.php?mod=viewthread&tid=139325&extra=page%3D1%26filter%3Dsortid%26sortid%3D47%26sortid%3D47这个帖子进行操作就成功了。对此非常感谢！
     
     后续入手一台唯科V90D旗舰版的机型，按照上述方法，ROOT成功后用R.E找到etc/vold.fstab文件后进入的界面不一样了，具体界面如下：

dev_mount sdcard /mnt/sdcard emmc@fat /devices/platform/goldfish_mmc.0 /devices/platform/mtk-sd.0/mmc_host
dev_mount sdcard2 /mnt/sdcard2 auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-sd.1/mmc_host
## Example of a dual card setup
#dev_mount left_sdcard /mnt/sdcard1 auto/devices/platform/goldfish_mmc.0/devices/platform/mtk-sd.0/mmc_host/mmc0
# dev_mount right_sdcard/mnt/sdcard2 auto/devices/platform/goldfish_mmc.1/devices/platform/mtk-sd.2/mmc_host/mmc2

## Example of specifying a specific partition for mounts
# dev_mount sdcard/mnt/sdcard2/devices/platform/goldfish_mmc.0/devices/platform/msm_sdcc.2/mmc_host/mmc1

请问该如何修改呢？谢谢！
