Try resetting the device and inserting a USB firmware upgrade key to perform the recovery. You can place the zip file on the USB and follow the README guide in the link below to start the process.

That sounds really frustrating! It’s strange that the recovery isn’t working. In my experience, pressing the hard reset button before powering it on and waiting for 15-20 seconds might help. Good luck!
