Offline Method for Step 6 part A: Download and unzip this pack, place the two wad files you get into the wad folder on your SD Card. Load WAD Manager, load iOS249, SD Slot and disable NAND Emulation. Navigate to the wad folder, highlight iOS53-v5406 [TB].wad, press A and install. Do the same for iOS55-v5406 [TB].wad
For me ios249 didn't show up, so I loaded ios36, I didn't see any option to disable NAND emulation. I installed iOS53-v5406 [TB].wad and iOS55-v5406 [TB].wad.
I then loaded Priiloader and got the message "CIOS infected IOS detected, aborting mission".
Where have I gone wrong?
