Could you re-enter DFU mode and try downgrading again with this command? /Applications/LeetDown.app/Contents/MacOS/LeetDown

You’ll then need to copy and paste the terminal log to here (or pastebin more preferably) to understand what’s going on.

Yes :)

I'm not quite sure, but I think it's a problem with futurerestore and not with LeetDown...

[rA9stuff]

It seems like your device got disconnected while LeetDown was uploading iOS 10.3.3 bootchain and failed to boot it. There are possible causes for this issue on M1 macs:

• You may not be disconnecting the USB cable from the mac itself (not the iOS device).
• You may have a bad USB cable and it may be causing issues sending the bootchain.
• ???

Could you provide the steps you're following while LeetDown is uploading the bootchain?

[enzovykm]

I disconnected the cable every "5 seconds cooldown" show up on screen but sill the same error.

As I cannot use an USBC to lightening cable, I use an USBC to USBA adapter then an USBA to lightening cable.
All that stuff is legit from apple and in good shape.

I opened a thread on Futurerestore but for the moment, I don't get an answer ...

[rA9stuff]

Make sure to reconnect the cable to the mac only when leetdown throws an error. Also, you may want to remove the issue from the futurerestore repo since the problem is not with futurerestore.

[enzovykm]

Okay, I just remove the issue from futurerestore.
Once again, there is still the same issue....
I might need to say that my device is on iOS 12.5.5 and its not Jailbroken

I had the same issue, finally I connect ipad to macbook directly，and it succeed. Do not use any adapter，when downgrading, remove all the adapter even though no device connect by.
