[HELP] Swapping Internal & External SD?

[chauf]

Hello.

So this is my first post on here. I previously had a UHost2 where swapping the internal/external SD cards I could just edit the vold.fstab file and reboot. Now I've upgraded to an MK902 running Quickshot 3.1.

There's no longer a vold.fstab file in KitKat so this method doesn't work any more. I've been searching around and found a build.prop tweak which also didn't work.

I've come across a few variations of an init.d script that unmounts the SD cards and then remounts them swapped. However, all the variations had different numbers in them for the blocks. I was wondering if anyone would be able to set it to the right numbers to work on the MK902. I haven't tested this script yet because I'm scared that if it doesn't work it'll mess up my device.

Here is the init.d script:

#!/system/bin/sh

LOG=/data/extsd2.log
echo 'mark 1' > $LOG
umount /storage/sdcard0
umount /storage/sdcard1
umount /mnt/secure/asec
umount /mnt/media_rw/sdcard0
umount /mnt/media_rw/sdcard1
mount -t vfat -o umask=0000,uid=1023,gid=1023 /dev/block/vold/179:33 /mnt/media_rw/sdcard0 1>>$LOG 2>>$LOG
mount -t vfat -o umask=0000,uid=1023,gid=1023 /dev/block/vold/179:33 /storage/sdcard0 1>>$LOG 2>>$LOG
echo 'mark 2' >> $LOG
mount -t vfat -o umask=0000,uid=1023,gid=1023 /dev/block/vold/259:0 /mnt/media_rw/sdcard1 1>>$LOG 2>>$LOG
mount -t vfat -o umask=0000,uid=1023,gid=1023 /dev/block/vold/259:0 /storage/sdcard1 1>>$LOG 2>>$LOG

Can anyone change it or get it to work on the MK902?

Or does anyone have another way to swap the internal and external SD cards on KitKat?

Thanks.

Search for it, somwhere bob explains that. In kit kat you can swap the sd card through vold.fstab but that is located in the boot.img if i remember well. You need to disassemble the boot.img find vold.fstab in there and reassemble it again and then flash it to your tvbox

Bob made me a boot swapped.img to do this, just flash the boot swapped.img & all will be good.. untick everything in the flash tool except boot,replace the original boot with this one

This method usually works for tv sticks like mk802iv, dont know if it works for tablets. Try to ask at the tablets place here on freaktab

It is easy to do it for mtk devices uder kitkat: Use the linux pack/unpack scripts for mtk (http://forum.xda-developers.com/show....php?t=1587411)
Unpack your boot.img file. Update the 3 fstab files, rebuild the new boot.img and flash it.

If you add the following line, you will also enable the OTG (you will be able to hot mount usb keys):

/devices/platform/msm_hsusb_host/usb2 auto auto defaults voldmanaged=usbdisk0:auto

will give it atry

Works fine again.
