I create a modded IPA for non jailbroken users and it works with appsync, I just cant sideload it... I cant even sideload the Original non Modded IPA,,,I have tried many Methods even downloading the old version of iTunes just to get the IPA file  and it still crashes

Are you sure your modification isn’t causing it to crash? You shouldn’t need to sideload it regardless, and if the only solution is to use a jailbreak, then have it as such for the time being.
