Project Marvel Contest of Champions

[AgriosApsu]

Hy guys,
This is my first attempt to mod a game...
I know that is difficult to mod...
But I have some programming knowledge.

I am dividing the project into 4 steps:
1- Extract
2 - Understand .dll code
2.1- Change a simple variablr
2.2- Decompile .dll
2.2.1 - Change de code
3- Zip apk
4- Sign apk (Meta-inf)


I am trying to use APKMuiltTool and AdvancedAPKTool for steps 1,3,4
And .NetReflector with reflexil...

Steps 1, 2, 2-1 it's OK...
I thought that steps 3 and 4 would be easy..
I thought...
I am trying to recompile using the two tools. The APK is generated, but it stops at the communication with the server screen.

Someone could help me...

I figured it might be in the use of the .netReflector. So I used IDA and HEX but in the same place. Any idea where I'm going wrong?

@icry4u
The problem is in certification.
What are you guys doing with signed games?

 

[Alamo March]

GitHub - Fuzion24/JustTrustMe: An xposed module that disables SSL certificate checking for the purposes of auditing an app with cert pinning I am using this for eXposed or this GitHub - iSECPartners/Android-SSL-TrustKiller: Bypass SSL certificate pinning for most applications for substrate

Hey buddy how are u getting on with this mod? I have looked all over the net and all i can find is one hack for apple devices. Where they are using something from cydia to downgrade the version of the app, and a mod to go with.

Anyway do u think youll be able to do one? If so what features u going for?

Regards

Any modification implies a new signature.
So far without success in passing this phase.
I tried some antiLVL techniques, but without success ...

So, you applied the changes and compiled apk back, but you can't sign it? Can you share modified code, I might be able to help with signature

i am also doing reverse engineering on mcoc I found that mcocmod uses some kind of API to bypass SSL certification

 

[Jason305]

Hope you manage to get somewhere with this. On that note,mcocmod was able to play on developers server it seems. He had access to all the character and all new content long before official release. There was even talks that he had plans to make his own server and mod where we could pay to be able to join it and play all content with all characters seperate from global? It would be amazing and cool if you guys could achieve something like this
