ah I got it now :D sorry, I thought you couldn't copy the kernel/initramfs to the archos because you use a linux on your desktop or something like that.

Hm.. Have you tried this?
  1. Start Terminal Emulator
  2. # su
  3. $ sh
  4. $ cd path-to-usb-storage
  5. $ ls -al
(note: replace "path-to-usb-storage" with the path you tried to write to)

what does it say?

Hi,

First i go root: su
then i open busybox: sh
then go to /mnt/storage/: cd /mnt/storage (here i got usb_host)
then i did ls -al

Result:

...
...
drwxrwxrwx 5 1000 1015 32768 Jan 1 1970 sdcard
dr-xr-xr-x 1 1000 1015 20480 May 4 11:39 usb_host


This meens that usb_host isn't writeable.
I Tried chmod 777 usb_host but then i get "chmod: usb_host: Read-only file system".
I get this with every USB i try (just a usb-stick or an external hard drive (250 gb, 1 tb, ... everything i have ))

Thx in advance for checking this out!

I have a question or problem. When I go to update firmware it says ...... USB connected ....... Click ok to disconnect .... I click ok ... But I dont have a usb connected and it never will update firmware. I get same message with or without the usb connected. I can manually push firmware but how do I push z1mage? Thanks in advance.

Is it really so hard to understand that you have to connect usb to a computer and copy the files BEFORE pressing the button?

This is weird. I tested this just a minute ago on my A101IT:
Code: 
$ adb shell


BusyBox v1.7.2 (2012-02-28 22:48:59 CET) built-in shell (ash)
Enter 'help' for a list of built-in commands.

/ $ su
su
# sh
sh


BusyBox v1.7.2 (2012-02-28 22:48:59 CET) built-in shell (ash)
Enter 'help' for a list of built-in commands.

/ # cd /mnt/storage
cd /mnt/storage
/mnt/storage # ls -al usb_host
ls -al usb_host

everything works as expected. the usb stick is formatted with fat filesystem, what is yours?

check "mount | grep usb_host" for more information

I'm sorry but how and where?
-> this link currently does not work
-> this link currently says that 2.4.83 is the latest version
-> this link currently says also that 2.4.83 is the latest version

Please tell me what you are refering to or I cannot help you. :(

    Hello community

    First of all, thanks to dogmaphobia for his initial work (click for fw 2.0.71)

    Don't forget: I'm not responsible for anything ;)
    Installing SDE or rooting your Archos device in any way may or definitly will void your warranty. You can find more information about it on the Archos website: link

    Now here we go, you need four things:
    1. An Archos Gen8 device (e.g. A101IT)
    2. Archos Firmware
      - 2.1.02: [Archos server]
      - 2.1.03: [Archos server, Mirror #1]
      - 2.1.04: [Archos server, Mirror #1]
      - 2.1.08: [Archos server]
      - 2.3.20: [Archos server]
      - 2.3.26: [Archos server]
      - 2.3.81: [Archos server]
      - 2.4.19: [Archos server]
      - 2.4.65: [Archos server]
      - 2.4.80: [Archos server]
      - 2.4.81: [Archos server]
      - 2.4.82: [Archos server]
      - 2.4.83: [Archos server]
    3. Archos SDE
      - [Archos server], [Mirror #1]
    4. Rooted initramfs + kernel
      - [fw 2.0.71 +rw]
      - [fw 2.1.02]
      - [fw 2.1.02 +rw]
      - [fw 2.1.03]
      - [fw 2.1.03 +rw]
      - [fw 2.1.04]
      - [fw 2.1.04 +rw]
      - [fw 2.1.08]
      - [fw 2.1.08 +rw]
      - [fw 2.3.20]
      - [fw 2.3.20 +rw]
      - [fw 2.3.26]
      - [fw 2.3.26 +rw]
      - [fw 2.3.81]
      - [fw 2.3.81 +rw]
      - [fw 2.4.19]
      - [fw 2.4.19 +rw]
      - [fw 2.4.65]
      - [fw 2.4.65 +rw]
      - [fw 2.4.80]
      - [fw 2.4.80 +rw]
      - [fw 2.4.81]
      - [fw 2.4.81 +rw]
      - [fw 2.4.82]
      - [fw 2.4.82 +rw]
      - [fw 2.4.83]
      - [fw 2.4.83 +rw]

    *: +rw = permanent root, changes to filesystem will be stored in /dev/mmcblk0p2. it has ~30 megabytes free, this should be sufficient for most changes and scripts.
    BE CAREFULLY: if you delete or corrupt important system files and aren't able to boot anymore, you have to flash the "non-rw" root kernel+initramfs, go to /mnt/system/unionfs and remove the changes.

    Then you have to the following:
    1. Install SDE (you only have to do this only once, it will even survive a full reformat)
      • reboot Archos device and hold down "Vol-" button after screen went black
      • choose "Update Firmware"
      • connect your Archos device by USB to your computer
      • upload the SDE firmware file to your device
      • safely disconnect the USB connection
      • press ok on Archos device
      • reboot
    2. Install android firmware
      • reboot Archos device and hold down "Vol-" button after screen went black
      • choose "Update Firmware"
      • connect your Archos device by usb to your computer
      • upload the Android firmware file to your device
      • safely disconnect the USB connection
      • press ok on Archos device
      • reboot
    3. Install the custom kernel + initramfs
      • reboot Archos device and hold down "Vol-" button after screen went black
      • Go to "Recovery Menu" and then "Developer Edition Menu"
      • choose "Flash Kernel and Initramfs"
      • connect your Archos device by USB to your computer
      • upload zImage and initramfs.cpio.gz to your device
      • safely disconnect the USB connection
      • press ok on Archos device
      • reboot and hold down "Vol-" button after screen went black
      • choose "Developer Edition"
      now you have temporary root (you always have to boot "Developer Edition" to get root again)
    4. (optional!) permanent root
      thus it will boot always the custom kernel (to revert, reinstall Android firmware)
      • reboot Archos device and hold down "Vol-" button after screen went black
      • Go to "Recovery Menu" and then "Developer Edition Menu"
      • choose "Remove Android Kernel"
      • reboot

    For Updates:
    Just go like this:

    I was in the same situation as you are: 2.1.03 and permanent root.
    Then did a firmware upgrade from the rescue menu, flashed the new kernel and initramfs and removed again the stock android kernel --> working :)

    If it says "update failed" the aos file might be corrupt
