INTRODUCTION
Today I resized my mother's Kobo Glo from 2GB to 4GB without opening the reader. The default configuration in some countries* only uses half the space that is available. This guide takes full advantage of the space available. It also works for the Touch according to xping.
(*See posts in this thread for a discussion on where Kobo has or has not put in 4GB SDcards.)
I upgraded my Kobo Aura HD using info form here. You exchange the SD-card on the inside of the reader with a bigger one. I am not doing this again, because I found that the reader became less rigid after opening and closing it a couple of times.
So it entails a few steps:
When you have done that the result is this:
32,6MB Used space / 3,14GB Free space.
THE STEPS
1. Install telnet.
2. Telnet into the reader over wireless network.
3. Repartition using fdisk.
I'm just going to give you the cleaned log of my session:
4. Do a factory restore.
You will lose all your books and added software when you do a full reboot. Backup your books and data before doing a factory restore!!!!
You have to power off first. Then hold the frontlight button while you pull the power switch.
The ereader goes into factory restore. It will reformat partition 3 (/dev/mmcblk0p3 ) and copy partition 2 to 3. After that it will try to upgrade to the newest firmware.
That's it!

1. Install telnet.
- Download Kevin Short's telnet hack from the thread telnetd broken with firmware 2.10.0?
- Plug in your ereader and connect to PC.
- Unzip an copy the file KoboRoot.tgz to the .kobo directory on your ereader.
- Safely remove the device and let it restart.
2. Telnet into the reader over wireless network.
- Install putty (Google it)
- Start internet on your ereader. Go to settings, go to Beta functions or extra, tap internet browser.
- Go to settings, go to information about device, write down IP-address. For me it's 192.168.1.88.
- Start putty. Put the IP-address in the box "Host Name (or IP address). Check Telnet under Connection Type. Click Open. This will start your terminal session to your ereader.
- At "(none) login:" type "root" press enter. Your now at the Bash shell prompt. Enjoy!
3. Repartition using fdisk.
I'm just going to give you the cleaned log of my session:
Code:
[root@(none) ~]# fdisk /dev/mmcblk0
The number of cylinders for this disk is set to 121008.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

The ereader goes into factory restore. It will reformat partition 3 (/dev/mmcblk0p3 ) and copy partition 2 to 3. After that it will try to upgrade to the newest firmware.
