I am getting "unfortunately key hash doesn't match any game" error when I try to link a facebook account with this game.
EDIT of Resolution:
I was able to fix the issue.
How to reproduce the problem:
I downloaded "[APK - Forum Link] [v4085] [MOD - Unlimited Lives & Coins] " the very first one. NOTE: I did not had installed the official one, this was a from scratch installation on this Samsung Galaxy tabet. Upon launching the app I got the "Hacked by ..." prompt which was expected, so far so good. The game started, I was able to start playing, I was on level one, I was getting the walk-in tutorial as a new member. Where the problem occurred was when I tried to link the game to my game I already had in progress on a facebook account. When I enter the facebook ID and password I would then get the KEY error that I mentioned earlier, this error would perpetually repeat itself until I force closed the app.
RESOLUTION:
I uninstalled the hacked app and I installed the official app. On the official app I was able to link the facebook account to the game, I saw my current level (level 52), then I closed the app. I installed Titanium Backup and Restore, performed a full backup of Toy Blast (Official app) and all its DATA. Then I uninstalled the official app. Then I installed the hacked app named above (v4085), but didn't opened it. Then I fired up Titanium Backup and Restored, browsed to Toy Blast and restored JUST the DATA. After doing that I went ahead and opened the app. I got the "hacked by...." logo, the app opened normally but this time I was on the facebook's game progress, I was linked to facebook account finally.
I played one game and in level 52 after exhausting all the 42 moves or so I lost, I initially through that the hack wasn't working properly since I was expecting unlimited lives, so I closed the program, I installed (as an in-place-upgrade) the hacked .apk without uninstalling Toy Blast (the hacked version), the installation succeeded, possibly performing any modifications to DATA (if it did, I dont know, can't confirm). Well anyways I played the level again, and I lost, but this time it hit me, by "unlimited lives" it meant that I had unlimited coins, I can purchase 5 additional moves perpetually until I win, and so I discovered how the "hack" for the unlimited moves works. With this said it was PROBABLY not necessary for me to had done that last installation of the .apk in place of the existing hacked app, it would have probably worked at that stage.
