Post Jailbreak Fixes

  1. Fix AFC2 Error : Blackra1n doesn’t adds the afc2 support to your jailbreaked iPhone. iPhone browser, iFunbox, Diskaid etc uses the afc2 service to access the file system and allow the transfer of files such as Winterboard  themes, NES ROMs or eBooks to the iPhone. In short you can’t access root partition of your drive with desktop clients.
  • Launch the cydia and search for afc2add and install this patch.
  • After installation reboot your phone and you’ll be fine again.
2.   Fix no WiFi after the Blackra1n : To fix broken WiFi Reset network settings, then reboot and WiFi will work again.
