Help/Support Cydia new repos for non jailbroken

[MrVibe 0 iPhone Xs Max 12.3]

Hello I’m getting in to the iOS world not very long ago and decided to jailbreak my iPhone XS Max but I cannot find anything for this model running iOS 12.3 beta, I do have cydia installed and been looking like crazy for a way to get the game CSR 2 installed on my phone, I search for it on the iOSGods.com and found but just on the forums and I don’t have no idea how to use those ipa links when I search for the game on the iOSGods app game section I can’t find it, I sent a message to Dida regarding a VIP membership to see if he or someone can help me figure something out, any help is welcome, thanks!

You can’t install mod menu on that beta. There is JB for iOS 12-12.1.3

Thanks for the fast response, where can I find the version of the jailbrake, from what I understood i have to downgrade my version of iOS and then re-install cydia then jailbrake on a earlier version of iOS is that correct? If you don’t mind pointing me to the right direction I really appreciate! I just did a backup of my apps so I’m going to reset my phone once I get the link to the jailbrake, thanks again
