I see you've found my post over on xda-developers.
Trying to piece everything together and understand how to do things from there can be very confusing (and they seem to make somethings even more complicated than they already are). Anyway...
For people running either Windows XP or Windows 7 on their computers...
I have just finished work on putting together a full package with everything needed to install the 'rooted' stock Archos 4.0.7 firmware. It contains:
The ADB USB Driver and instructions for how to install it (with pictures).
The needed ADB files.
The 'rooted' 4.0.7 firmware and matching Kernel files.
The UN-official SDE installation files.
And one jim dandy of a .bat file that can take you through just about the whole process.
I've zipped it all up into one 210Meg .zip file. You should be able to download it from this link
For those that really know what they are doing and only want/need the UN-official SDE...
I've created a smaller 12Meg .zip file that does not include the 'rooted' 4.0.7 firmware files.
You should be able to download it from this link
If the download links do not work for you then send me a private message and I'll see what else I can do.
Just remember that I will not be responsible for any damage or data loss that may occur.
You would be doing this totally AT YOUR OWN RISK!!!A note about the Archos Video and Music Player apps (aka MediaCenter)
Since the official Archos 4.0.26 firmware uses a different method of indexing media files than older firmware did, when you try to use 'rooted' firmware versions based on older Archos firmware you may need to do the below for the MediaCenter apps to be able to find your video/music files:
- Open the system settings.
- Open the "Apps" category in the left pane.
- Switch to "ALL" in the right pane.
- Scroll down the list to "Media Center" and click it.
- Hit "Force stop" and confirm the warning.
- Hit "Clear cache" (if it is not grayed out).
- Hit "Clear data", confirm the warning again.
- Hit the back button in the lower left screen corner.
- Find "Media Storage" in the same list of apps.
- Repeat the process of force stopping and clearing the data.
- Go to "Repair & formatting" in the left settings pane.
- Hit the "Reset multimedia library" item and confirm on the next screen.
