I have and Archos 35 Home Connect I upgraded recently to latest firmware (2.4.83)

Unfortunately, I have some issues now and I would like to downgrade it

So I'm trying to find older firmwares but this seems to be impossible

Indeed, all the links I found point to Archos website where only the latest version is available (2.4.83); all previous ones have been removed .

Does someone have a copy of them or is there somewhere I can find them ?

Note : I do not remember which version I had before I upgrade but I assume it was not a very old one
