Im having an issue where everytime I try to tether, i'd simply get a message saying "Tethering started with errors. Check log to view problems" but everytime I check the log it says "error: file log does not exist". My phone is rooted and I did set the profile to S3. My only issue is that everytime I set the profile to S3, it says "profile set to GT-I9300". My model is SPH-L710. Could this be the issue?
