Unable to boot device after restoring about downr1n

[dualra1n]

I'm trying to downgrade iPhone 7 to 14.8

futurerestore completes successfully, but when I run ./downr1n.sh --boot I get this:

[*] Pwning device

usb_timeout: 5

[IOKit] Waiting for the USB handle with VID: 0x5AC, PID: 0x1227

CPID: 0x8010

Found the USB handle.

Stage: RESET

...

There are hundreds of [IOKit] Waiting for the USB handle... lines.

Additionally, while executing device cyclically appears and disappears in Finder. It doesn't react to button combinations at all, so I can't re-enter DFU or perform force restart.

I used ./palera1n --dfuhelper to exit DFU, it just prints <Info>: Waiting for devices, finishes and nothing happens.

Sometimes it shows <Error>: libirecovery error: -3 (Unable to connect to device).

I tried to downgrade multiple times, run ./downr1n.sh --boot on another PC with Linux - behaviour the same. However, in this state, I can restore and update device using Finder.

First: execute sudo ./binaries/$(uname)/gaster pwn, if that start to loop (like never finish) Force reboot when the loop stop please press home button (or volume down) and stop gaster by pressing ctrl + c in your computer and after 10 second execute the command again. Remember before you run --boot you must be sure that you are in the real dfu mode

It works. Thanks!
