KV My Kindle stuck on the tree screen after updating to 5.9.8.2

Hi,

My Kindle Voyage was running the firmware 5.8.9 after I manually updated it to 5.8.9.2, it is stuck on the tree screen.

I did 40 seconds hard reset, and I also left it on charging for at lease 1 hour then 40 seconds hard reset again. They didn't work.

Is there anything I can do before I contact Amazon, please?

Thank you!
