Beginner’s Guide: iOS IPA Modding Using Windows

( No Jailbreak – No Frida – Static Modding )

Personal Note:

I don’t know everything, and it took me quite some time to figure this out. But I’ll still explain everything in as much detail as I can, using simple and easy language to help beginners like me.

Important Note: This method is only for those who want to try modding on Windows. It’s not as powerful as some of the advanced tools you can use with a jailbroken iPhone. Also, it can be time-consuming if you don’t know what you’re doing at first—so keep that in mind before you start.

I don’t know how to attach pictures here, so sorry about that—lol.🤣🤣

Tools and Files You Will Need:

Spoiler

1: Windows PC
2: IPA File of the Game
3: HxD (Hex Editor) – Free, Download Here: https://mh-nexus.de/en/hxd/

4: Il2CppDumper – Free, Download here: https://github.com/Perfare/Il2CppDumper

5: Notepad++ – Free, Download here: https://notepad-plus-plus.org/downloads/

6: Sideloadly – Free, Download here: https://sideloadly.io/

7: Apple ID – Needed for signing apps with Sideloadly.
8: 7-Zip – Free,
• OR WinRAR –

Read These Things First :

What You Can Do with This Method:

Spoiler

   •   Modify offline iOS games that use Il2Cpp structure.
   •   Change game values like coins, health, damage.
   •   Disable unwanted features by changing hex codes.
   •   Perform Static Modding (editing the game’s static code).

What You Cannot Do with This Method:

Spoiler

•   You cannot bypass server-sided checks.
   •   You cannot live test changes without reinstalling the app.
   •   You cannot bypass advanced anti-cheats with just this method.
   •   You cannot modify Swift-based or encrypted games easily.

Limitations of Windows-Only iOS Modding:

Spoiler

   •   No live testing: You must install the IPA every time you make changes to see if it works.
   •   No dynamic hooking: You cannot use tools like Frida without jailbreak or macOS.
   •   Trial and error required: You need to test several RVA addresses and hex edits repeatedly.
   •   More time-consuming: No instant result like Android modding with Frida.

What is Static Modding?

Spoiler

   •   This method is called Static Modding because:
   •   You are editing the compiled game files directly (libil2cpp.dylib) using a hex editor.
   •   The changes become part of the IPA permanently.
   •   You cannot dynamically change anything while the game is running.

How to Download Decrypted IPA (Required for Modding:

Spoiler

When modding iOS games, you must have a decrypted IPA. Normal IPAs from the App Store are encrypted and cannot be modified.

Method 1: Download from iOSGods (Decrypt Store)
   1.   Open your browser and go to:
👉 https://armconverter.com/decryptedappstore/us

   2.   This is the Decrypt Store by iOSGods.
   3.   You can search for the game you want. Example: “Subway Surfers” or any offline game.
   4.   Look for a decrypted version compatible with your iOS version. Download the IPA file directly to your PC.

Notes About Decrypted IPAs:
   •   The decrypted IPA is already ready for modding.
   •   The encryption is removed, so you can extract it, edit, and resign it.
   •   If the game you want is not available, you may need to dump the IPA yourself from a jailbroken device.

Why Decrypted IPAs Are Important:
   •   App Store IPAs are encrypted for security.
   •   Encrypted IPAs cannot be opened, dumped, or edited.
   •   Decrypted IPAs allow us to extract libil2cpp.dylib and global-metadata.dat for Il2CppDumper

Step 1: Prepare the IPA File

Spoiler

   •   Change .ipa to .zip.
   •   Extract it using 7-Zip or WinRAR.
   •   Go to: Payload → GameName.app
   •   Find these files:
   •   libil2cpp.dylib
   •   Data/global-metadata.dat

Step 2: Dump the Game

Spoiler

•   Open Il2CppDumper.
   •   Load libil2cpp.dylib and global-metadata.dat.
   •   Wait for dump.cs file to generate.
   •   Save dump.cs safely.

Step 3: Analyze dump.cs

Spoiler

   •   Open dump.cs in Notepad++.
   •   Search for keywords:
   •   coins, currency, gems, gold, health, damage, setHealth, addCoins, getCoins, etc.
   •   Write down the RVA (Example: 0x1D7280C) of suspected functions.

Step 4: Open Hex Editor

Spoiler

   •   Open libil2cpp.dylib in HxD.
   •   Go to: Search → Goto → Enter RVA address directly (remove the ‘0x’ part).
   •   This will bring you to the instruction in the hex.

Step 5: Known iOS Hex Codes for Common Functions
   •   NOP (No Operation) → 00 00 → Used to skip instructions.
   •   True (MOV R0, #1) → 01 00 A0 E3 → Makes a condition always true.
   •   False (MOV R0, #0) → 00 00 A0 E3 → Makes a condition always false.
   •   BNE (Branch if Not Equal) → Change to BEQ (Branch if Equal) to reverse condition.
   •   Compare Instruction (CMP) → Sometimes you can remove this to disable checks.
   •   Add Value Example (ADD R0, R0, #1) → Change to higher numbers to increase gains.
   •   Subtract Instruction (SUB) → Try to NOP it to stop decreasing values.
   •   Jump (B instruction) → NOP a conditional jump to always pass.

👉 You need to understand patterns and compare similar functions to guess what to change. Justg Do alittle Research How it works ,

Step 6: Save Your Edits
• After editing in HxD, click Save.
• Do not corrupt the file size or structure.

Step 7: Repack the IPA

Spoiler

   •   Make sure the folder structure is correct:
   •   IPA → Payload → GameName.app → (all files here)
   •   Select the Payload folder → Zip it → Rename to .ipa.

Step 8: Resign the IPA

Spoiler

   •   Open Sideloadly.
   •   Load your modded IPA.
   •   Connect iPhone.
   •   Enter Apple ID → Start signing.
   •   Install the IPA.
   •   On iPhone → Go to Settings → General → Device Management → Trust your Apple ID.

Step 9: Test the Game
   •   Launch the game.
   •   See if your changes worked.
   •   If not, try other RVAs, other hex edits, or revisit dump.cs.

Important Notes Keeeeeeep Thisssssssss Innnnn Mindddddddd:

Spoiler

   •   Each game is different; you may need to try many times.
   •   Always backup original files before editing.
   •   You will fail several times before succeeding. Trial and error is the normal process.
   •   Static modding takes patience but works for many offline iOS games.
   •   If you don’t understand some parts, you can search on YouTube or Google, or ask in modding communities for help.

Warning Cause You Knowwww 👀👀👀👀:
   •   Do not attempt to mod server-sided games. Cuz You cant not Possible.
   •   Do not use this method on multiplayer or ranked games. Very Hard You have to Try and check tons of Stuff , Often tese games are completly server sided too .
   •   This guide is for educational and personal offline testing only. Yeahhhhhhh
