imei repair and remove frp is available in sigma.

For flash & factory reset 1st authorize by sigma and use sp flash tool.

Code:
This option is designed to service Mediatek devices that require authorization of the bootloader. This solution opens up more opportunities of servicing using other third party service software, like*FLASH TOOL, etc.
