idevicerestore Restore failed with macOS IPSW greater than 15.4 on Apple silicon Mac (M1)

When using idevicerestore to restore my Macbook Air M1 with a macOS build version greater than 15.4 (15.4 and 15.4.1), after sending restoreKernelCache, the MacBook restarts into DFU again, therefore the restore process fails.

If using any macOS IPSW before 15.4, the restore process proceeds normally

How should i debug this problem ?

Ubuntu 24.04.2 idevicerestore 1.0.0-231-ga5905b7 (libirecovery 1.2.1-13-g638056a, libtatsu 1.0.4-8-g7e1647b) usbmuxd 1.1.1-69-g523f700

The macOS version is actually 15.4, but I can confirm that it happens for me as well. macOS 15.3.2 is the newest version I can restore.

Yeah, I somehow mixed up the macOS version with the iOS version—sorry about that.

Can confirm this on M1 Macbook Pro (2020) was able to install macOS 15 (Base) and upgrade to latest version. Anything after 15.4 is borked

I am also experiencing this issue for M1 Mini. Restores on M4 Mini appear to function, though missing the restore progress screen.

I have tested on an M2 Mini, and it works for the M2. So it may be isolated to the M1. I will see if I can do other tests as well.

Not sure what I am doing differently, I am running it in Arch Linux off a Raspberry Pi. I have used both the AUR install for idevicerestore, as well as compiling versions.

Here are the versions I am running. idevicerestore 1.0.0-232-g8061f08-dirty (libirecovery 1.2.1-13-g638056a, libtatsu 1.0.5) usbmuxd 1.1.1-69-g523f700

I see the same behaviour with current tip of master (2914bf6) on my M1 Air 2020 - 15.3.2 works, any later version fails with the same error

Please re-test with latest code, I pushed a commit that hopefully fixes this.

@nikias can you confirm that the fix is related to device failing at exact kernalcache moment and restarting ? My m2 pro is literally dead tried a lot and it always fails at that point like OP here mentioned. In My case no file worked.

The error was fixed after updating to the latest commit (Tested using ipsw 15.6.1 on my M1 Mac). Thank you ~
