I installed Light Biz OS firmware on GeekBox yesterday, but I’ve quickly realized many applications such as Gimp Inkscape would not install due to the small 1.94GB “internal partition”, so I asked how to increase the partition size in GeekBox forums last evening, and got an answer overnight from “dewet”.
The good news is that it worked so I’ll share the steps I followed in a computer running Ubuntu 14.04. It might also be possible to perform the same tasks within a Windows machine with Rorkchip’s Factory tools
- First let’s download the utils with relevant scripts and binaries:
12git clone https://github.com/geekboxzone/utilscd utils/rockdev - Now copy your device or board’s firmware file “update.img” to the working directory, and unpack it:
1./unpack.sh update.img
The output should look like:
1234567891011121314151617181920212223242526start to unpack update.img...********RKImageMaker ver 1.61********Unpacking image, please wait...Exporting boot.binExporting firmware.imgUnpacking image success.Android Firmware Package Tool v1.0Check file...

The files will be in the “output” directory. - For our purpose “parameter” file, and especially the last line (CMDLINE) where we will want to adjust the userdata partition size:

This can be done manually in a Linux editor, but I played it safe and instead downloaded and installed RK_ParamEd.exe for windows, and change the 2048 MB set for userdata partition to 6144MB (6 GB).
Save, and we can see how the end of CMDLINE changed:
10x00C00000@0x002BC000(userdata),0x00020000@0x00EBC000(radical_update),-@0x00EDC000(user) - Now we can repack the image, after moving the content from the output directory to rockdev directory.
12mv output/* ../mkupdate.sh
A successful repacking should look as follows:

- Done! I now have a 6GB internal storage partition in Android 5.1 based Light Biz OS operating system.

I Was trying to resize partition for internal storage on my android image and found a trouble

Unpacking image, please wait…
Error:Check update.img failed!

Do you have any advice?
Here is a much simpler way. Step one use rkflashtool to back up the raw image and change the partition.txt to the size your want it and reflash it and back up the new image thats bigger. Step two mount both the images as loop devices. Like so: losetup -f User1gig.img losetup -f User2gig.img Step three sinces they are raw ext3 or ext4 images your can just use dd to clone them. dd if=/dev/loop1 of=/dev/loop0 Now just resize /dev/loop0 with gparted. loop -d /dev/loop0 / 1 Now you just reflash back your new image resized to whatever you want it… Read more »
small comment, command to clone needs “.git”
git clone https://github.com/geekboxzone/utils.git
hello
its possible increase partition recovery android ?
use program RK PARAM???
you suggestions step by step examples, to recovery???
tankyou…
