Help me bypass GoogleSignatureVerifier!!!

Hello guys,
I've already written there but I think that was the wrong forum.

I need to bypass google signature check in application Waze in order to mod Waze and bring back radars in France!

I think I've found the smali files to patch which is googleSignatureverifier.smali.
I try to spoof the genuine signature but I get crashes every time!

I think some of you have already broken this type of security since it is necessary to mod GAPPs!
