Help/Support Modifying IPA makes it crash

[R3tr0_X 0 iPhone 11 Pro 17.0]

So I modified an iPA using WinRAR, and sideloaded it on my Jailed iPhone. But it immediately crashed and kicked me out. 
 

Is this because I have to resign the iPA? If so, how do I resign it? 
 

I’m on iOS 17.0 my device is Jailed and I have a Windows Laptop. 
 

If anyone knows how to resign it please help me.

Depends on what you're modifying. Sideloading via Sideloadly will re-sign the IPA for you and may help. Sideload Spoofer would also assist.

Well Rook thanks for replying.
I am using sideloady but the game crashes and kicks me out. but I'll use Sideload Spoofer to see if the game still crashes or not.

Editing an IPA directly using a HEX editor can be challenging. If it's crashing then you have done something wrong. Could be wrong hex values or the wrong spot for the hex value.
