How to remove signature verification in apk skinermax?

[RomanFR]

Hello masters. I have the full modded skinermax apk, but I'm trying to modify it with apktool and apkeditor. Exactly I want to remove the time limit in which he asks to update forcefully. After compiling it, I install it and when I open the game I get a message that the application has been modified or is corrupt, then when I accept it, it sends me to install it from google play. Without doing any modification the same thing happens (only decompile and recompile). Also try to delete the verification code but in doing this the application does not open. Could you tell me with what program or in what way can I remove the verification? Or how did you crake it before? I am new at this. Thank you.

that's because compile/decompile would change signature and/or hashcode. given you still get the verification popup, that means you haven't cleanly removed things

Thanks for answering master BTG. Then how would i clean it properly?
This type of security would be in several smali files? because I only saw that a file has this. I am new at this. It would be so kind please to pass me some tutorial, to be able to guide me. Thanks again.
