Host: Macbook Pro 2017 / macOS Ventura 13.6.5 Device: iPad 6 / iOS 17.4.1

Executing 'palera1n -c -f' following a DFU restore on an iPad 6 running 17.4.1 results in either a hang or an error that suggests that a fakefs already exists. "cannot create fakefs over an existing one".

Interestingly, the error appears on device after unplugging it from USB. If I do not unplug the device, it appears to hang (forever?)

I then tried executing 'palera1n --force-revert -cf' which resulted in an error - (I have typed up an extract of the log):

mount(...)
hfs: mounted palera1n on device disk3

IOServiceOpen: 0

this operation is not permitted. (this apfs volume role is not recovery role [0x0002 != 0x0004])
cannot delete fakefs disk1s8: 53 (os/kern) denied by security policy
Assertion failed: (0), function create_remove_fakefs, file fakefs.c, line 271.

Rootless mode appears to work correctly.

Palera1n beta 9 for iPadOS 17 does not support the creation for rootful, I would recommend you try and just do palera1n -l as thats the only supported option.

As for the issues you're encountering, a failsafe is being triggered as it thinks the fakefs location is at /var/mobile.. because obviously you wouldn't want to overwrite a system partition. It would end up badly, so it just fails.

Hi! could you please try the nightly builds here? https://cdn.nickchan.lol/palera1n/c-rewrite/artifacts/main/420/binaries/

Setup fakefs: ./palera1n -cf --cli Setup bindfs: ./palera1n -Bf --cli Boot rootful: ./palera1n -f --cli Remove rootful: ./palera1n -f --force-revert --cli

[khcrysalis]

^ these are builds which have those issues fixed, would recommend you try them!
