Raspberry Pi 4 boots PongoOS

[Halconmilenario21]

Hello, I am using Checkra1n build 0.1337.2 on a Raspberry Pi 4 to jailbreak an iPhone 7 plus with iOS 15.7.3. It boots into a PongoOS shell, loads the KPF, the ramdisk, the overlay and boots in verbose mode, but I don’t see the Checkra1n app on the screen and I can’t SSH with iproxy. I’ve thought that either the ramdisk or the overlay was corrupted so I’ve extracted them again nd I’ve got the same result. The rdsk and the overlay are put in a specific memory address by the KPF, so they are there. Could XNU be omitting the ramdisk? If not, is the ramdisk not loading the overlay?
