There have been so many questions on this during my few days that I have been here, that I decided to make a short tutorial on how to do it.
Perhaps someone finds it useful enough to make it sticky.
I found it very simple and did the copying into the root directory only once (for the first time) and then did it with the RKAndroid.
That's really simple. You get it here
My operating system is Windows 7 Ultimate 32bit but I also tried it on the Home Premium 32bit. And I read that Home Premium 64bit and Windows XP are also working.
One thing in advance: For the flashing with the RKAndroid software your device must be switched off !
So do this right now. Draw the power switch to the left until you get prompted to power down the device. Achknowledge twice.
Then push the switch into the "lock-position" to the right.
After that make sure that the device is connected to the power cord
and connect it to the computer with the USB cable.
Now turn the Archos round and put a pin the reset hole and push it.
When you do this the first time the driver is probably not installed yet.
Windows tries to install it but will leave you with an error message.
Please forgive me having a German Operating system. I will try to translate the most important things.
It says driver had not been installed.
If you take a look at the device manager you will see an unknown device listed there.
Double click on this and "update driver"
Choose the update from your local computer
Now look for your RKAndroid directory and go to the place the driver is stored e.g. E:\Archos 7\RKAndroid_ENG\Driver\x86\win7 for Windows 7 32bit.
For the 64bit system choose the equivalent.
Acknowledge and install.
Now you have been successfull. In some cases it occurs that you get a warning as this driver is not certified. Ignore and install anyway.
As you can see now the device is known now to the operating system as RK28USB
After that you can either start the Apad-flasher
or the RKAndroid
. They are both the same. You have to start the program as administrator.
Click on the open button with the "..." and choose your Image.img that you want to flash.
Say open and click "Restore".
Acknowlegde the warning and do it !
After you get the success window unplug your device from the USB and power it on.
If it can't be switched on directly reset it one more time and move the switch.
It will then carry out the update.
