I am getting this on my 2023 Macbook Pro M2, that machine has the hard-drive wipped and I just wanted to install Somona again.

I got the same error with the following debug log when restoring an iPad.

NOTE: No path for component iBEC in TSS, will fetch from build_identity

In my case I can see in the debug it tries to send the iBEC, it doesnt error at all however it looks the device doesnt seem to be responding. I've been using a generic ThunderBolt 4 cable, I praying this is the issue. I've an official apple as the official procedure suggest, early waiting to test it all again with it.

[Leon-cam]

I've encountered this issue before. After I updated the libirecovery and rebuilt the whole project, the issue was resolved. Hope that would help.

[felipedbene]

I've found the reason, I was putting the machine into recovery (not DFU). After setting up dfu correctly, even Apple official tool worked.
