Resize Partition on Android
When you installed a custom rom on your android phone/tablet, the default partition allocated to maximize storing data. Sometimes you want to resize a partition because its too small, or remove it because its no longer required. In this case, you will remove two partitions, and create a new larger /cache partition in that space.

WARNING: Back up all the important data before proceeding.

Make sure you put your android device in USB debugging mode
Boot your android device into recovery mode
adb shell
parted /dev/block/mmcblk0
unit s
print
write down the partition table (all starts and stops, you WANT to save this for reference)
rm 26 (current cache location, this will delete it)
rm 27 (old tombstones/preload location, this will also delete it, freeing up equivalent of about 250MB)
print (This is where you will see your changes, and now you are going to use the free space between block 25 and 26 for your new /cache partition)
mkpart
choose logical
Use the end sector from 25 as the start sector. (parted will tell you if this ok)
Take the start sector from 26 and subtract about 2-5MB of sectors (to get an idea of size, each sector is 512 bytes) This will leave enough space for a mmcblk27 placeholder, to maintain partition layout
enter ext2 (partition type)
print
mkpart
choose logical
Use the end sector of 26 as the start sector.  (parted will tell you if this ok)
use the start sector of 27 as your end sector
enter ext2 (partition type)
print
reboot into recovery
format /cache
reboot
