Modifying iOS ipa files using ida - Bad_apple - Dec 20, 2017

I have an iPhone X not jail broken and can sideload apps downloaded using VShare helper and Cydia impactor easily.  

I have an ipa I downloaded that I have modified some Boolean values in ida by changing some binary and patched it to the ipa. My question is after doing this can I just sideload the ipa like other ones I have downloaded or does the app need re packaged somehow or re signed??

I have tried just side loading the ipa with Cydia impactor and vShare helper but they both just error.  Actually vShare helper gives me more detail saying the bundle identifier is not prefixed.  I don’t need a how to or a tutor just someone to point me in the right direction. Thanks!
