Easy way to resize kindle partition?

[zxcvbs]

hi is there any easy way to resize a kindle 2/3 root filesystem?

To get more mb i had to:

Backup

dd if=/dev/mmcblk0 of=/mnt/us/mmcblk0_7688.dmp bs=512 count=7688
dd if=/dev/mmcblk0p1 of=/mnt/us/mmcblk0p1.dmp
dd if=/dev/mmcblk0p2 of=/mnt/us/mmcblk0p2.dmp
dd if=/dev/mmcblk0p3 of=/mnt/us/mmcblk0p3.dmp

cp the files to a local machine. and

Edit partition table

sudo sfdisk -d mmcblk0_7688.dmp > ptable.txt

edit the partition table on ptable.txt

sudo sfdisk --no-reread -f mmcblk0_7688.dmp -O PT.save < ptable.txt

cp mmcblk0_7688.dmp to kindle storage

ssh kindle

dd if=/mnt/us/mmcblk0_7688.dmp of=/dev/mmcblk0 bs=512 

umount mmcblk0p2 mmcblk0p3 mmcblk0p4

mkfs.vfat /dev/mmcblk0p4
mkfs.ext3 /dev/mmcblk0p3
mkfs.ext3 /dev/mmcblk0p2
dd if=/dev/mmcblk0p1 of=/mnt/us/mmcblk0p1.dmp


cp mmcblk0p1.dmp to a local machine

Resize Filesystem

local machine

tune2fs -O ^has_journal mmcblk0p1.dmp
e2fsck -f  mmcblk0p1.dmp
resize2fs  mmcblk0p1.dmp
tune2fs -j mmcblk0p1.dmp

cp mmcblk0p1.dmp to kindle usb storage.

kindle
dd if=/dev/mmcblk0p1 of=mmcblk0p1.dmp

Reboot.

Im on the work, so some commands are missing, this is more a question than a procedure to resize.
Always flash your kindle with Yifanlu custom kernel before or you will brick it (and have at hand a restore.bin backup).
