Note: If you screw up your tablet doing this, it will not be covered under warranty. Hardware defects should still be covered. If you have found anything helpful, please click "thanks" on my post, and visit the original threads of our amazing developers and leave thanks there too! Before you go on, please BACKUP ALL IMPORTANT FILES YOU DO NOT WANT TO LOSE TO A SAFE LOCATION.
If you have rooted other android devices before, rooting your Archos G9 may be a little difference. Instead of rooting stock firmware, We first install SDE (special developer edition) firmware using official ARCHOS firmware. Once SDE menu is installed it adds an option in recovery to install developer firmware. This is when we install a modified firmware that has busybox and super user included. This guide is very safe to follow. Chances are most problems you run into are very easy to recovery. Please view the FAQ at the bottom of this post if you have questions or run into problems. Because we don't have to flash recoveries or mess with the bootloader like some Android devices require, and because all methods are universal to G9s, this rooting process is very safe and easy to follow. This guide is very easy: No need to install any drivers, root methods, anything! Not even ADB is required. So easy, your grandma could do it...? Quote from ARCHOS:
Important notices to be acknowledged before downloading and installing the SDE firmware:
- Once the SDE firmware is installed on a device, this device will be watermarked and ARCHOS will be able to detect that this firmware has been installed once.
- After SDE firmware installation, you will not be able to play DRM protected content anymore.
- Installing the SDE firmware is considered by ARCHOS as a voiding of the warranty and ARCHOS declines all liability and responsibility for any issues resulting from the installation of this SDE firmware.
- ARCHOS strongly advises that only experts in embedded software development should install this firmware.
- This firmware is provided "as is" and is not supported by ARCHOS.
The firmware must be installed on a unit with a firmware version above 4.0.1 (Ice Cream Sandwich). Once the SDE firmware is installed, powering on the device while pressing the 'volume down' button will now trigger a "Boot Menu". This menu allows to select which operating system is to be launched (Android, the newly installed Developer Edition or the Recovery System). If the device is powered on while pressing jointly the 'volume down' and the 'volume up' buttons, the Developer Edition will be launched. If the device is powered on without any other button pressed, Android will be launched.
Installing a new ARCHOS (Android) firmware WILL NOT remove the SDE firmware. In order to uninstall the SDE, boot into the recovery using the Boot Menu, select "Developer Edition Menu", then "Uninstall Developer Edition".
STEP 1: Install SDE
Step 1: Download SDE firmware HERE
Step 2: Boot into recovery by holding the volume rocker up and pressing the power button simultaneously
Step 3: Select "Update Firmware"
Step 4: Plug your device into your computer using the USB cable that came with your device

This method may void your warranty if you screw up something software related. Your device will be marked and Archos can detect if you have this installed. If you wish to follow a slightly more difficult (possible dangerous) method, which will not mark your device, you can follow it here (note you will need ADB installed): http://forum.xda-developers.com/show....php?t=1542058
