[patsfann]

Was hoping someone (dev) could make a ROM just for Wi-Fi ..without any network searching for this phone its not connected,, I just use it like a tablet... Thank you in advance. P.S. (preferably jelly bean or kit kat)......

I don't know about JB or KK, but here is an ICS rom for deactivated devices such as yours
[ROM][For inactive devices]Ubersonic RC3 is … | HTC EVO 4G | XDA Forum

Heavy debloated system
Removed as many traces as i could find of access to phone such as:
Signal bars (wifi and bluetooth still show)
No service is finally gone and so are the Emergency call things on secure lock screens
Dialer, contacts, messaging, calendar, email, and many others
Baseband setting and device info, cmstats, and system update
