You should have read the note

- This method may not work for all games. Google and game developers use advanced security measures and server-side checks that can detect even minor tampering. Bypassing these security protocols is outside the scope of this guide.

I have learned to make Unsigned apk with google login and it worked. But the problem is with this method the game which has only google play games sync. I can't sync my google play game account. At first it shows the google Play pop up when I first install modified unsigned apk but when I exit and open again It doesn't connect anymore. Also the game progress and achievements don't sync.
ChatGPT says "your Core Patch successfully bypasses the local Android system signature check to allow the installation, but Google's cloud servers are rejecting the app identity and dropping the connection.
Question: How can I force Google Play Services to maintain the authenticated session and sync my progress/achievements with the modified APK?

Note: I don't have root , I use Virtual Master rom: Android 11

There is a reason I added a note: This method may not work for all games. Google and game developers use advanced security measures and server-side checks that can detect even minor tampering. Bypassing these security protocols is outside the scope of this guide.

Also, that's interesting that ChatGPT helps you with modding related, while it always refuses to help me with it

Actually it's google AI. If you ask him anything he will search related websites and give you appreciate answers but his solution are not consistent.
Also will you tell me is there any way to sync with google play games. Becoz with this method google play games shows error saying you are offline.

Use Swift backup to backup your data, install game from play store then restore data. May not work with some games because they even detect data restoration and it will proceed as no data are saved

How to backup app data using Swift Backup app (Root only)

Most users probably don't need a backup tool since most games comes with login system, or transfer ID. But some offline games does not offer an option to backup or you can't backup because you haven't paid the game, or using signed APK, or broken Facebook login. To use Swift Backup properly...

Please help me with this, I've been struggling for days.

I'm using core patch and it works because I tested a pre-made unsigned apk mod which had the mods working with in-app purchases available

I install the app through google play store, then use x-plore to move the officially installed app to my pc, where I use winrar to extract the meta-nf folder, stamp-cert-sha256, and essential signature files if needed. After everything's extacted, I uninstall the app, then use apktool mobile to decompile the apk mod, delete the meta-nf folder, replace it, add the stamp-cert-sha256 to the folder named “original”, then I do “compile this project” (both aapt versions and all the options for "select signature file" were tested) and install.

The apk mod works like normal, but it still doesn’t let me do in-app purchases.

Honestly, I don't even know if my method ever worked with in-app purchases. But this is expected for security reasons to protect users from purchasing things using tampered/infected APK, so I'm not looking into it.
