Is it possible to fix my A10X iPad stuck into recovery mode after DelayOTA?

[i1itione]

The device is iPad Pro 2 (12.9 inch), it was iOS 13.7 and I used Chimera to jailbreak it, but now I want to upgrade it to iPadOS 16.6, therefore I follow the DelayOTA guide, setup every needed things and restore RootFS in Chimera before applying OTA.

After OTA downloaded, I press install button to start installing the update, and the iPad reboots few times and there is progress bar, but now the iPad stuck into recovery mode, maybe something wrong happened during installing OTA files?

Is it possible to fix this problem via SSHRD? Because I don't want to updgrade this iPad to iPadOS 17 by iTunes.

Have you tried using the command line tool iRecovery?
./irecovery -n

Yes, but no luck, then I tried using FutureRestore with dumped blobs via SSHRD, I got a problem with firmware key not available.

(the device info seems contain personal id, I replace it with xxxxxxx here)
