Is your spark 3 kb7 or kb7j? If you’re not certain which is your phone’s exact model then you’ll have to try both firmware.
Download the firmware @ https://forum.hovatek.com/thread-27738.html
use software download tool @ https://forum.hovatek.com/thread-23709.html to flash the firmware.

The flashing shouldn't have even taken place. You should have got an error at the very beginning which would cause the phone to go dead. If this is correct, then what you need is https://forum.hovatek.com/thread-808.html
BTW, why would you even think of flashing spark 2 on spark 3?
