I recently bought an Archos 50 Neon, it's a nice phone but with slight touchscreen delay (I hope you get what I mean by that).
I saw a firmware update for this phone but the link didn't work, NOT ANY link to a firmware update on the Archos website works! So my question is: Does anyone have a (custom) ROM or the file of the update. Oh and one more question: The update is only loading a update.zip file on the root of the phone, so if you can just name a costum ROM it update.zip should a custom ROM work without root? (this question has low priority)

Thanks For Your Help
