there will be message [secure boot]... in the logs if the device has secure boot. there's none in the log you posted
how did the device go totally dead? by reading info in nck box or it was dead before then?
disconnect / reconnect the battery of the device then use SP flash tool to attempt flashing firmware then post the result here

firmware is listed @ https://www.hovatek.com/forum/thread-15631.html
there's no indication that the device has secure boot so use default DA and you've not answered any of my previous questions
