Just so there isn't any confusion here.
- Currently there is NO working 3.56 CFW, spoofed or otherwise
- 3.56 OFW can be decrypted, but not customised and SIGNED.. yet
- You do NOT have to update, and it is strongly advised not to
- Devs are looking into it as we type, but it could be a while yet
- The DNS 'trick' is confirmed working for some, but not all users
- Recovery mode / update via USB has NOT been removed in 3.56
Bottom Line: Hold tight on your current OFW/CFW until further notice.
