...

did you try "fastboot oem unlock-go" ?
and did you try other methods of fixing imei that don't require root? see https://www.hovatek.com/forum/thread-116.html ; modem meta, sn writer e.t.c

To root, patch stock boot.img using magisk @ https://www.hovatek.com/forum/thread-21427.html and flash the patched boot.img using SP flash tool
