most probably split apks. Download from here .

Thank you, now it's at least clear how to do it.
However now I'm able to only change some specific characters. When I tried to change whole string to another one with smaller length, it broke app completely.
So I can replace it with same length strings only.
Another question to those who may know:
there are tools like UABE/utinyripper, they allow to extract resources from the game. But what if I need to simply replace one image with another? Is there any simple way of doing it?

Personally, I have never tried that, but try using UABE and UnityEX. Both of these are commonly used to achieve what you aim to do.
It's unity, I was able to open up the project in unity after extracting with UTinyripper, most things was there (I have used unity for more than a year now) so I doubt it's split apk as you say. This is the game if you are interested in taking a look "My Foxy Girlfriend"
(I mean most things but without the scripts of course) this is my first time trying this but I read a lot of tutorials already. This game seems to be a lot more difficult than the norm.
Edit: and yes, there is no Assembly-CSharp.dll either
Download from here. Chose default , arm7 , default and download apk.

I also want to ask, could you direct my to some resources I can read to learn about that ARM opcodes or whatever it's called? The values I want to change are method arguments and I can't find any suitable method just returning int32 which is what's covered here.
well here we see how to modify the values returned by a function that returns an int32, but the game I'm trying to hack does not have any function like that for that value I want to modify. It just has public properties and set methods with an int argument. Like SetPoints(int point) or soemthing like that
Ok ... On Arm arguments comes with R register. First Arg as R1 , 2nd one as R2 and so on. If you want modify it , just return a value on the register that getting the value of R1. Or Maybe xerf and set R1 a value for R1. Or try storing value on the field. Its kinda advance topics. Better start with basics. And if you on Discord can add me Gourov #4039.
Very impressive guide. You're the best
I have a question
You said below
01 00 A0 E3 = MOV R0, 1 = ldc.i4.1
It's hex code, arm assembly and opcode
so ldc.i4.1 = MOV R0, 1 and I can change this asm code at the Online ARM to Hex convert
Perfect!! except one thing
How do you know opcode ldc.i4.1 is MOV R0, 1.
I know opcode and can make some function or edit code but I don't know how to convert to ARM asm code
Please tip to me

Its not about converting its about return type. On IL opcodes Idc.i4 returns integers. Idc.i4.1 returns 1 or true. On Arm MOV returns int thats why MOV R0 , #1 returns 1 or true. I dont think you can convert IL to Arm. rather than you should learn Arm.
Hello, thanks for the thread. It's easy to follow but i don't know why but i can't install the apk
Step one to seven , done
First I checked the arm code first
I tried to experiment a bit as I only want to change the value and I'm not sure if the crit calculation stop only from there so i didn't input the ret. But wait folks, don't raise the pitchforks yet for not following the guide as I did that as my next attempt.
I copied it to HxD and save the lib then i move it to my apk.
For my signer, I used One Click Signer.
I tried the excactly same as the tutorial when inputing the arm in the example after using the converter but still "App not installed".
