Re-flashed my S3 back to stock to sell it; how to test it?
Had some problems with data on my S3 and couldn't fix it, so I got an S4 as a replacement.
I want to sell the S3 now but obviously want to make sure it is working correctly. I flashed a stock ROM via Odin, etc., so I think it would all be working again.
Can't I simply log into my Sprint account and put the "old" phone back on my account to see if voice, text, data, etc. are working? Then change it back without CSR intervention?
