Thumbs down converting sm-p602 to sm-p601

Hi Mates, i have region specific SM-P602 ( 3G/Wi-Fi ) it is same as p601 but phone call restiricted firmware. With macrostr patch it is possible to converting firmware to SM-P601 but i cannot install new 601 firmware directly.
How can i install p601 firmware with odin? Do i need PIT file?
