PMT FREE MOD Barbie Dreamhouse Adventures Ver. 2024.8.0 MOD APK | Premium Unlocked

Should this be unlocking Barbie Dreamhouse VIP Club or any of the content locked behind it? I still get the subscription popup when I try to access any of that.
 
Had some time during lunch to figure out apktool, Smali, and Ghidra. Pretty cool stuff! I don't have a publicly rootable Android device to mess with the save files directly and my daughter was begging me for VIP and coins. I managed VIP but the best low effort patch for coins ("Dream Dollars") I could figure out was unlimiting the daily $50 gift timer. I'd share but I only bothered with the 32-bit version since that's what her tablet runs.

I started by patching IsPurchased(Ljava/lang/string;)Z to always return true:

Code:
.method public IsPurchased(Ljava/lang/String;)Z
    .locals 1
    
    .line 528
    const/4 v0, 0x1
    
    return v0
.end method

Then I did the same for a handful of functions in libil2cpp.so with some ARM assembly: SubscriptionManager$$get_IsSubscribed, LockableItem$$IsPackUnlocked, and DailyGiftManager$$HasEnoughTimePassed.

Generally, I just added 01 00 a0 e3 mov r0, #1 after the function prologues immediately followed by the epilogue.

I was initially going to patch in some code to write new values to the save file but hesitated when I saw some annoying salt fields. I did go ahead and neuter SignedSaveFile$$IsSignatureValid in the meantime. I also saw some code that looks like they can hotpatch remotely, so I imagine I'll need to work on a root if I want to persist my changes while also persisting her save.

Was cool to figure out how to use all these tools!
