I have the same issue with my iPhone 5s. |

Same issue on an iPhone 6, tried both the included ramdisk and one from armbian. |
|
My iPhone 6 is on iOS 12.5.6 as well. I tried it on an iPhone 5s also running 12.5.6 and I got the same result |
|
iPhone 6 on 12.4.8 |

This PR should fix at least this issue for you :) https://github.com/konradybcio/pongoOS/pull/4/files |

@jrote1 that definitely did the trick for me on an Apple TV Gen 4 👍 |

Following HOWTO.md, I compiled pongo on a macbook (intel macbook pro running macOS 11.6.5) and booted into pongoOS using checkra1n 0.12.4, on an iPhone 6 running iOS 12.5.6. Here's the output from checkra1n:

Again following the guide I compiled the kernel, this time on a vm running Ubuntu 22.04.1 LTS. following the rest of the steps and running load_linux.py, it seems to be a success and i get the following output:
Waiting for device...Loading initial ramdisk...Initial ramdisk loaded successfully.Loading device tree...Device tree loaded successfully.Loading kernel...Kernel loaded successfully.Booting...Success.However here's what shows up on the iPhone screen:
After maybe 5 seconds, the iPhone just restarts and iOS comes up as normal. I'm not sure where to begin troubleshooting so any help would be appreciated
