Hi, if anyone is still interested...
I have got Real Racing 2 HD working on the Galaxy tab 7.7
What you need is the following:
1) Real Racing 2 .apk (version 000 366) or Demo from market
2) Mali SD Data if you can find it on Google placed in correct file path which we all should know by now.
3) Internet connection
4) Real Racing TB Backup
What I did, was anstall the .apk and then I used root explorer to place SD data in File location. after launching the game it didnt fully load up but wanted to start downloading extra data.
Let it download if you can, sometimes you get a NaN indication or it will seem as if nothing is happening but it should start, if not and force closes or comes up with download not complete and progress saved, just start it over, it took a few times for mine to work, I also jumped from wifi to carrier network while starting the download so not tsure if that helped or was maybe a cracked .apk to start with but mine downloaded and was playable, if it turns out to be the demo then just google the net for Real Racing 2 Titanium Backup and restore the data only.
Sorry for the very mixed up way but after many atempts to install this game this was my only way of getting it to work
Enjoy!
EDIT: I have got the full correct version now working, all menu options correct.....use the latest version (000 640)
Download new data, working 100%
