Kindle Voyage can't proceed past the initial "tree" screen

Hello,

I recently purchased a kindle voyage from a secondhand shop. I was using Calibre and had a whole bunch of documents in the kindle that I just wanted to delete and start over, so I deleted everything in the documents folder, transferred content via Calibre (to the machine memory - or so it said). Deleted things from the kindle cloud and then took disconnected the kindle via the proper steps (Disconnecting the usb via the pc first, then unhooking the usb.)

Upon unhooking the usb it gave me an error saying I didn't disconnected it and it needs to fix. I got impatient after an hour and tried to reboot to have it get stuck at the tree screen.

I tried charging it until the light turned green restarting via long-pressing the power button and plugging it into the pc and all those steps to get it to work to no avail.

The Kubrick method appears to not work for the Kindle Voyage and from what I see, I can't add any files onto my kindle as it doesn't allow me to access its folders (it does show it is connected, and that is a kindle device - but nothing else)

Anyway, am I shit out of luck or is there some miracle solution?

Any help would be appreciated :).

Thanks
