if you can boot into recovery mode (power off the device then vol up + power button), perform a factory reset
if it doesn't fix it then download and flash stock firmware ; download depending on your build number @ https://www.hovatek.com/forum/thread-35594.html

next time, don't clear frp using miracle, instead format frp partition using sp flash tool @ https://www.hovatek.com/forum/thread-21638.html
