Is the imei you have now the same as that at your battery compartment of your phone? I.e is it the original IMEI?

Can you get another TECNO CM CA6?

If you can, read nv ram from it and write to your phone https://www.hovatek.com/forum/thread-25457.html (note that this is possible with the latest version of miracle, you need box)

Am unable to flash the NVRAM files using SP flash tool due to locked bootloader... I get SECURE BL error. And sometimes it gives authentication file error

Try unlocking the bootloader then flash the NVRAM. You can re-lock bootloader afterwards.
Do not hold any button when connecting to PC
