Default [TUT] How to Install Official SDE menu and rooted firmware (updated 19 Nov 2012)


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:

  • 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

 
Prerequisites: You must own an Archos 80/101G9 and be on fimrware 4.0.1 (ICS) or higher.

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
Step 6: A new drive should appear in "My Computer", copy the file you downloaded "firmware_archos_it4.aos" to this device
Step 7: Press the power button and wait for the instalation to finish


STEP 2: Install rooted firmware.

 
Before you begin, you will need SDE installed. Please follow step 1 before you begin if you have not already. If you have SDE installed, you can continue. Any downloaded applications and personal media should remain untouched. 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". Please download files to your PC hard drive.

Please visit the following thread by surdu_petru and download and extract:
- Stock_Root_4.0.25.zip - 206.48 MB

http://forum.xda-developers.com/show....php?t=1955910

Step 1: Power your device on
Step 2: Once your device is on, and your home screen is visible, plug your device into your PC. If you do not have ADB installed on your computer, skip steps 3-6 and follow step 6a.
Step 3: Open a command prompt on your PC and type
Code:
adb devices
Step 4: Ensure your device shows up so you know it's connected properly and adb is active
Step 5: Type
Code:
cd desktop
This is to change the directory to where you download the two files

Step 6: Type
Code:
adb push archos.ext4.update /mnt/storage
Give it some time to transfer, it is a large file and will take several minutes, you will be presented with transfer info once the transfer is complete.

Step 6a: If you followed steps 3-6, no need to follow this step. If you do not have ADB, you can simply copy archos.ext4.update to the root of your Archos storage (the main folder when you connect your Archos).

Step 7: Power off your device
Step 8: Boot into recovery by holding the volume rocker down and pressing the power button simultaneously
Step 9: If you see "Archos Boot Menu" or something similar, select "Recovery System"
Step 9: You should now see "Archos Recovery" with the following options "No" "Reboot" "Update Firmware" "Repair System" "Format System" "Developer Edition Menu". Select "Developer Edition Menu"
Step 10: Select "Remove Android Kernel" (if the option is present, if not, skip)
Step 11: Select Flash Kernel and Initramfs
Step 12: Copy zImage and initramfs.cpio.lzo to the drive that appears
Step 13: Reboot your device. Your device should now be rooted.


Frequently Asked Questions! (FAQ)
Will this guide work for my Archos 80 G9? For my 101 G9? I have Archos 101 G9 OMAP 4430. I have 250GB hdd model! I have turbo edition!
 
Yes this guide will work for ALL Archos G9 users. This includes 80 G9s and 101 G9s. This includes all 8gb G9s and 16gb G9s and 250GB G9s and 1.0 GHz G9s and 1.2 GHz G9s and 1.5 GHz G9s and OMAP 4430 G9s and OMAP 4460 G9s and board version V5 etc etc. ALL G9s!


Can I just drag the .zip file to the RAMDISK that appears when I flash zImage and initramfs?
 
No! Archos recovery cannot read ZIP files. You must first EXTRACT, then copy the contents of the extracted folder. NOT the folder itself. This means you will have two files on the RAMDISK, and no additional folders. If you don't know what a RAMDISK is, try Google or Wikipedia. If you get stuck in a boot loop because you forgot to extract archos.update.ext4 or drive.zip, you must follow the instructions below.

Help! I am stuck in a bootloop! Archos splash screen appears and keeps rebooting. I messed up when I was rooting, and now android will not boot! I accidentally formatted my device, and now I cannot boot into android.
 
This is a simple mistake and in 99% of cases it is easy to fix. Follow these steps:

Step 1: Download official Archos G9 firmware for ALL G9 tablets (aos file) HERE
Step 2: Boot into recovery turning your device off and then holding volume down + power at the same time
Step 3: Choose "Update Firmware"
Step 4: Connect USB cable to computer and tablet
Step 5: A removable device should appear (RAMDISK), copy the file you just download straight to that drive
Step 6: Press the power button once the file is done copying. DO NOT UNPLUG your device until it has finished updating and has booted back into android.

If you did not format your tablet or delete any personal media, your files should be unaffected.

Will I lose SDE menu if I update my tablet with official AOS or OTA update
 
As of the latest update, no official update from Archos has removed SDE menu. You should be fine, and your SDE menu should remain untouched.



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

Hi!

It's OK !

..once you removed Android Kernel -> the second time does not appear....so the option is not present !

Android kernel is "official" one and bootloader uses it by default (reboot= stock firmware is loaded)

Recovery checks:
-if stock kernel is present- option Remove Android Kernel is visible in SDE menu
-if SDE kernel is present- option Uninstall SDE is visible in SDE menu
No kernel=no option to remove it
Code:
setprop persist.world.domination 1

I have installed SDE using your previous guide (I haven't rooted it yet, since I'm still sceptical). Is it safe to remove it and install the official one? I remember one post on the other thread, which said that you can't add it again if you uninstall it. Here it is.

Also, can you unroot by just flashing the official firmware?

not sure where he got that from. you can always add it again if you've uninstalled it...official or nonofficial

Yes its always safe to remove the SDE menu, sde firmware etc. If you run into troubles, simply reflash official firmware. It's worked for everyone else. If you have SDE, then getting sde firmware is simple and safe. I'm not sure what you're sceptical about or what you mean "you haven't rooted it yet". you mean you have SDE menu, just no SDE firmware? if so, simply place archos.ext4.update on the root of your internal storage, then boot into recovery and flash zimage and initramfs

I have since stated why re-installing SDE was not working.

http://forum.xda-developers.com/show....php?t=1648538

One can always get SDE back after uninstalling.
Even easier, now that the official SDE .aos has been released.
