Don't listen to this tard.
To answer your question, yes you
can, but I would never recommend that. If anything you can sell your CFW and get good money for it. Also if you have a CFW with mods on it, then update to 4.21, you will still have the GTA IV mods you originally put on it, you just will never be able to change the mods or add things to it in the future.
