Changing ROM in Dell Venue 7 Wifi I have a Dell Venue 7 (only Wifi) which is a piece of crap - too many bugs and Dell has stopped supporting it. Is there a way to put Cyanogen or anything else on it?
You can root Dell Venue 7 and put some custom roms on it (if there are any). But I think, best you can do is root the phone and play with it.

Root: 


Download One Click Root. Install One Click Root onto your PC or Mac.
Connect your device to computer by a standard USB cable.
Enable USB Debugging.
Run one click root.


Custom Roms with custom recoveries: (Read EDIT below)

Note: Sadly it is a Intel-based phone with less popularity, it doesn't have enough research or tools provided by developers to try out cool roms.

Here is the link to custom roms &amp; recoveries for venue, you can try them 

(I've doubt if they will work for Venue 7):

EDIT: Pointed out by Andy Yan, that custom roms provided in above links are for the original Venue (phone) released back in the days of Android 2.2
