[Xperia SP Q&A, Help & Troubleshooting] Mumups:
Hi, so I'm trying to follow a tutorial to spoof a Samsung Galaxy S3 so I can download a game from the Google Play Store.

Here is the SP build.prop for reference

So, I changed to ro.product.model=GT-I9300 and ro.product.manufacturer=samsung

Deleted Google Play Store data and rebooted like the tutorial said.

I go into Google Play Store app, and still it says that it is incompatible (although the web version says I can install it - problem with that is after I push the download from the web version the phone fails to download it)

So I'm asking what more do I need to change in build.prop? The first time I tried this I put my phone into bootloop and I don't want that to happen again

Any help would be much appreciated.

P.S: My android version and phone is good enough to run this app so no problem there
