[Q]for surdu_petru How to Undo things?

[55mls]

Since, for whatever reason, Archos seems to refuse to provide anyway to ever go back to older firmware versions...

I followed surdu_petru's instructions on how to install an UN-official SDE after the mess Archos made with their 4.0.25.

That all went well, and I could install his "stock" Archos 3.2.80, his "stock" Archos 4.0.7, and even tried several of his other custom ROMs.

Found I had to do a total re-format to get rid of the Apple screen crash animation of one of them though to get back to normal, but now here's my REAL question:

Just what do I have to do after all of that to actually revert back to a totally clean stock system with no traces of any of that stuff left behind?

In other words, how do I totally clean things up in case I need to send it back to Archos or if I want to sell it to someone else?

I know I can go into Recovery and re-format it, and also remove SDE, but does that really remove ALL TRACES of having been rooted and the other ROMs I've installed? Or, do I need to use ADB to clean things up, and if so, just what ADB commands should I use?

Hi!

You can clean your device 100% if you have not installed officialy SDE.
SO, go back to un-officialy sde, remove sde, format system- reformat device and copy official Archos firmware 4.0.26 .aos and flesh it!
Good luck! :good:

So, I should first boot into SDE and select remove sde and then come back into recovery to reformat, and then install the official Archos .aos. That will remove ALL traces of all of the other rooting and custom ROM stuff I have tried out correct?

After the mess with the Archos 4.0.24 and 4.0.25 firmwares, my only hope to ever get back to 4.0.7 was by following your instructions to use ADB to install the un-official SDE. A REALLY HUGE THAN YOU for those instructions and especially for posting the Enable_SDE.zip file. That made things real easy!

And, i did not even need to install the Google SDK at all (that is mentioned in many places otherwise).

I just put the tablet into developer mode, installed the ADB USB Windows driver (from the Archos website), downloaded and extracted your Enable_SDE.zip file, and then followed the rest of your instructions to then install your stock 4.0.7 rooted. I only had 2 minor problems...

I had to work around some odd stuff with the way the ADB USB Windows driver installs. Was just another of Window's odd quirks with that.

The other problem was the reboot after adb pushing the rooted firmware. My G9 tablets do not seem to catch the volume button being held in with a reboot. Works better to do a shut down at that point instead. Then it does catch the volume button being held in on a fresh start up to get into SDE to copy the 2 kernel files onto the device.

Again, many, many thanks for all of your help and hard work!
