Help! Il2CPP Hex editing

[Maki ☽]

Hello, im new to modding and i decided to learn some modding and mod "Slime - Isekai Memories" so my problem is each time i edit something in the Il2cpp.so file and i compile the game and i open it it crashes, heres everything i do step by step, btw its not the apk or the emulator i've tried to run the original apk without editing anything and it works, but if u still want to know from where i got my apk and what emulator im using, got apk from "apkcombo.com" and the emulator im using is bluestacks 5


1.Decompile it using "Apktool"
2.Dump the Il2cpp.so file using "Il2CppDumperGUI 1.5.3"
3.Open Dump.cs with "Notepad++"
4.Open Il2cpp.so using "HxD"
5.Find the value i want to change for example lets say "get_GemAmountRequiredToRecoverStamina"
6.Copy the hex corresponding to "get_GemAmountRequiredToRecoverStamina" and find it in "HxD"
6.Edit the hex for example lets say Im trying to make the amount required to recover stamina as low as possible so, 01 00 A0 E3 1E FF 2F E1
7.Save the file
8.Replace the old file with the new file
9.Compile and sign the game once again using "Apktool"
10.Install it
11.Open it
12.Crash!!!

Am i doing something wrong?, help me please

Which lib folder did you get the libil2cpp from?

Only 1 lib folder appears when i decompile it which is "arm64-v8a", dont know why theres no "armeabi-v7a"

if its arm64, the op codes will be completely different. For example: 0 would be 00 00 80 D2 C0 03 5F D6

look up arm64 hex codes

It still crashes but now it crashes on the screen where normally the logo of the company would appear, when i was using the wrong hex codes it crashed instantly

I just tried 2 different games and they all crash, so idk what im doing wrong, btw this time i did use the correct hex code corresponding to the folder from where i got the lib file

In the other post you made where i gave you a subway surfers method, set it as false with the armv7 code since it only has armv7 libraries

@Sekeu002 you will mod Slime - Isekai Memories ? before you try mod make sure check your device phone was support arm64 or not.make sure your was above minimum andorid 8 and see the spec first before you play use cpuz or similar app. i recomended use phone not emulator. if you really want emulator than you must have powerfull gaming pc.
