+==== Repartitioning ====
+Download partition table [[http://paz00.ru/index.php/File: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 ..."

+$nvflash -r -q --download 5 part5.img
+$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]]
