==== Repartitioning ====
Download partition table [[http://ac100.wikispaces.com/file/view/part.cfg|part.cfg]]

and command file in the same dir
<file bash repartition.sh>
#!/bin/bash

# Change this paths to you own
nvflash=~/ac100/ldk/bootloader/nvflash
fastboot=~/ac100/ldk/bootloader/harmony/fastboot.bin


mkdir work
cd work
$nvflash --bl $fastboot --sync || exit 1
echo -n "Making a backup .."
for i in $(seq 2 6)
do
    $nvflash -r -q --read $i part$i.img || exit 1
done
echo " Done"

read -p "Press [Enter] key when device rebooted to new recovery mode ..."
echo -n "Creating new layout .."
dd if=part2.img bs=1 count=4080 of=original.bct
ln -s $fastboot bootloader.bin
$nvflash --bl bootloader.bin --bct original.bct --setbct --configfile ../part.cfg --create --verifypart -1 --go|| exit 1
echo " Done"

read -p "Press [Enter] key when device rebooted to new recovery mode ..."
echo "Restoring backup .."
$nvflash --bl $fastboot --sync || exit 1
$nvflash -r -q --rawdevicewrite 0 1536 part2.img
$nvflash -r -q --rawdevicewrite 1792 1024 part4.img
$nvflash -r -q --download 5 part5.img
$nvflash -r -q --download 6 part6.img
echo " Done"
</file>


You should power on you device in recovery mode and connect it to the computer via USB.\\
Edit **repartition.sh** to fix pathes for **nvflash** and **fastboot.bin**\\
and run **repartition.sh**\\
While repartion you also need to reboot ac100 in recovery mode twice (script will ask you for it).\\

You could return default layout back using this file: [[https://raw.github.com/Stuw/ac100-repart/master/configs/default.cfg|default.cfg]]
