Non responsive iPad (A1893 6th gen 9.7")

Hi,

My iPad went into a boot cycle loop, it wasn't low on battery and I had no indication that there was any problem with it.

When I picked it up to use, it was in the boot cycle loop.

So I tried the hard reset option, it would reset but came back up in the same boot cycle loop.

Next I tried putting it into the recovery mode in order to try and restore it to operation that way, I tried this in both the restore and recovery options.......

Several times for both...

Every time I get a message indicating that it is not possible to restore/reload my iPad with the error code 4013.

Is there anything anyone can suggestI try at this point, to do I have a completely dead and unrecoverable iPad.

Any assistance would be gratefully received.

Thanks

NB: I should have mentioned it was already running iOs16.2, before the problem described above occurred.
