WTF
Revision as of 07:12, 1 April 2018 by Ryan Kovatch (talk | contribs) (added links for PurpleRestore and Apple Internal Apps)
This is run on DFU Mode and loads a secondary DFU-like interface. WTF Mode stands for "What's The Firmware" according to PurpleRestore and a quick look at some internal binaries.
Version 1
This doesn't appear to do anything. It calls the same functions in the VROM that the VROM calls to run the DFU. The only observable difference is that this WTF is slower. This may also allow large files to be uploaded.
Version 2
Version 2 enumerates a new DFU with PID 0x1227. This DFU does proper signature checking and allows IMG3 files to be uploaded.
