Help! Game won't launch if recompiled

[eco999]

I'm modding GrandChase. If I get a clean APK, decompile it, recompile and sign it, I can install the APK. However, I will get an error upon launching it saying "Unofficial app detected. Please download the official version", and the game won't load. I didn't even make any changes yet the game recognises that it's been decompiled and recompiled. How can I get around this?

I've tried searching the error message in the .smali and .xml found no results.
Tried searching "cheat" in dnSpy but the results don't seem related to an anti-cheat.
Tried ticking "Keep original signature" in Compile settings for APK Easy Tool.
Tried ticking "Prevent decoding/copying of unknown asset files" in Decompile settings for APK Easy Tool.

This game is heavily protected, and requieres bypass to even recompile it.

Thanks for the info.

Try to kill the signature, instead of using the same one, if this isn't working try to do a signature bypass with lucky patcher. Reminder: All can be hacked.

Thanks, I'll try that.

Try adding .apk files as an extension reference in WINrar so you can pull what you need without having to decompile or extract the archive in anyway, then sign it with lucky patcher or apksigner from the playstore works just as well for me try that maybe. If not sorry I lack the expierence to give much suggestions
