I have a major problem but i think there is a way to fix it, i just cant figure it out. i was adding google wallet on my rooted s3 and when reverting the build.prop file to its original form, i just copied and pasted the backup and renamed it to the original build.prop to replace the new one using root explorer. my phone does not boot up now i get the samsung startup screen and it shuts off. i could get into cwm recovery mode. any way to fix the build.prop without being able to fully boot the phone? i am on a mac but i could have access to a pc tomorrow if i need.
