Tell us about your setup:

  1. What iDevice are you using? iphone6s
  2. On what version of iOS is it? 12.1
  3. What version of checkra1n are you using? 0.12.4 and i compile the pongoOS myself
  4. What is your host system (OS version? Hackintosh? VM? etc.)? macos 11.5
  5. How are you connecting to the device (USB-A? USB-C? Apple/3rd party cable? Through a USB hub?)? usb-a

What are the steps to reproduce the issue?

  1. run ./checkra1n -k PongoConsolidated.bin -p
  2. run "./pongoterm" 3.run "sep pwn" there shows that "please upload a valid sepi img4 to run this attack" on the phone. I don't know why because it's work well on my iphone7, i've read the sourcecode of PongoOS, it seems that SEPFW is in the memory? But why does the SEPFW of iphone6s can't be parsed well?
