Maybe you did not disable verified boot
Flash stock boot and recovery for your current build number with mtkclient https://www.hovatek.com/forum/thread-40866.html

Disable secure boot using MTK Bypass @ https://www.hovatek.com/forum/thread-37957.html

Then Flash stock boot.img and recovery.img using SP Flash Tool @ https://www.hovatek.com/forum/thread-159.html
