itunes says that i should remove password before i download itunes, but my iphone is disabled!!

In other words - you don't need the itunes app on your phone to enable your phone.

You need to connect your phone to a computer that has itunes on the computer. (Or if it is a mac running catalina or later, you use finder on the computer)

Do not confuse iTunes Store app (on an iPhone) with iTunes app on a computer.

To regain access to your iPhone, you need to connect it to a computer running the latest version of iTunes, as per these instructions:--> If you forgot the passcode on your iPhone, or your iPhone is disabled

Disabled phone

If you forgot the passcode on your iPhone, or your iPhone is disabled

Can you open your phone normally or does it say it is disabled?

If it says disabled them I gave you a link and you need to use the exact combination of button presses given there.
