I tried to downgrade my phone to a custom version of 4.2.8 and it booted and showed no MEID apparent problem however I shut it off and now it's stuck in DFU mode I got a 160X error and now keep getting -1 errors for the most part and tried to boot the phone with redsn0w. Will apple notice if I take it in the genius bar that it has a custom IPSW?
