[SH-03C]Expand sdboot space

//Please reboot your SH-03C with bootkit and press focus key to stop the count timer.

// Initialize.
> adb shell
$ _su
# /bin/sh
~ # sd
~ # rw /mnt/sdcard

// Make "data_ex.ext2" file and format it!
# dd if=/dev/zero of=/mnt/sdcard/sdboot/data_ex.ext2 bs=1M count=[expanded size(MB)]
# losetup /dev/block/loop0 /mnt/sdcard/sdboot/data.ext2
# losetup /dev/block/loop1 /mnt/sdcard/sdboot/data_ex.ext2
# mkfs.ext2 /dev/block/loop1

// Mount SDcard.
# mkdir /data /dataex
# mount -t ext2 /dev/block/loop0 /data
# mount -t ext2 /dev/block/loop1 /dataex

//Copy data area to dataex area.
# (cd /data && tar cf - .) | (cd /dataex && tar xvf -)

//Then, please cd to /mnt/sdcard/sdboot to change the filename.
# cd /mnt/sdcard/sdboot/
# mv data.ext2 data.ext2.old
# mv data_ex.ext2 data.ext2

// Unmount all mounted point and reboot.
# cd /
# umount /data /dataex
# reboot recovery

//After your device reboot, please go to Android "settings" -> "microSD & phone storage" and check Internal phone strage. If you got more space, congratulations!
//Of course, you can remove "data_old.ext2", but you should backup this file before you remove because new "data.ext2" file may have some problems^^;



<<If you are using sdboot_r2, please try this.>>

// Initialize.
> adb shell
$ _su
# /bin/sh
~ # sd
~ # rw /mnt/sdcard

// Make "data_ex.ext2" file and format it!
# dd if=/dev/zero of=/mnt/sdcard/sdboot/data_ex.ext2 bs=1M count=[expanded size(MB)]
# losetup /dev/block/loop0 /mnt/sdcard/sdboot/data_app.ext2
# losetup /dev/block/loop1 /mnt/sdcard/sdboot/data_ex.ext2
# mkfs.ext2 /dev/block/loop1

// Mount SDcard.
# mkdir /data_app /dataex
# mount -t ext2 /dev/block/loop0 /data_app
# mount -t ext2 /dev/block/loop1 /dataex

//Copy data_app area to dataex area.
# (cd /data_app && tar cf - .) | (cd /dataex && tar xvf -)

//Then, please cd to /mnt/sdcard/sdboot to change the filename.
# cd /mnt/sdcard/sdboot/
# mv data_app.ext2 data_app.ext2.old
# mv data_ex.ext2 data_app.ext2

// Unmount all mounted point and reboot.
# cd /
# umount /data_app /dataex
# reboot recovery

// I think you can't get more space in "microSD & phone storage", but don't care.
// If you want to check whether you could got more space correctly, please type these command.
> adb shell
$ busybox df | busybox grep /data/app

// After you type these, you can see these messages.
df: /mnt/secure/asec: Permission denied
/dev/block/loop1	655104	60484	561340	10%	/data/app
					^This means available space!
