Downgrade iPhone from 4.3.5 to 4.3.3

Thursday, July 28th, 2011

I upgraded to ios 4.3.4 and then 4.3.5 and finally wanted to go back to 4.3.3. At this point I tried to download the ipsw of 4.3.3 and restore with it via itunes. But I get the error:

The iPhone could not be restored . This device isn’t eligible for the requested build.
  1. Upgrade to 4.3.5 OOOOOPssss
  2. Add

    to the end of /private/etc/hosts

  3. Download the 4.3.3 ipsw
  4. Use Pwnagetool in expert mode, giving it the 4.3.3 ipsw, this creates a custom ipsw
  5. In Itunes option+restore using the custom ipsw
  6. After that restore is done, RE-option+restore in iTunes, this time with the regular 4.3.3 ipsw
