Hey, first of all thanks a lot for the reply, and I indeed did not know about checksum verification, I googled and yup everything went over my head but atleast I got my answer as to why it was happening, and since you didn't say anything about bypassing it, I don't suppose its possible? I will share with you the (.hl) file structure if you want and the il2cpp.co or whatever (I browsed the net and found out this il2cpp also has something to do with checksum and I just checked my game files and yup this is there too)
Anyways let me tell why I was doing what I was so maybe there's a better way to do it, as I already said in my post its for getting old items into my new ID, earlier it used to be possible because I could just change the date on my emulator and the game would work I downloaded the previous version and set the right date, but now it doesn't work, earlier I used to go back even 6 months and get older items, but now I can't even go back more than a month, and the game says 'failed to load cloud data" and goes into " offline mode" so I can't even access the store even though the items are right infront of me
Now my thought process was like this-
Want old items>go to previous version and date like before (failed)>check if game guardian can help(no game guardian can only forward the time)>check if something can be done through game files(yes found out the information of my account like items, accessories, currency stored in .hl file)>try to modify(checksum verification failed and ID got reset to new, all progress lost)
I even tried to look into game files through Cheat Droid, APK Editor and other similar apps, I did find a lot of things but unfortunately I didn't understand any of it
So please tell me,
1. If there's a simpler way to access the store when I go back to the date with the right version, like if we can disable/enable something in the app files to get it enter online mode like before and sync the cloud data
2. Or if this checksum verification can be bypassed and I can simply use the .hl file of my old ID to have the same items in my new ID
3. Or if Game Guardian can help my in getting the items by figuring out the code or address or anything because I have access to the old ID also
Please keep in mind I'm totally new to this so I can follow instructions but don't have the knowledge of any of this stuff apart from what little a google search can tell me
