Hello.

As You can see from Software log, phone's modem part is damaged:
This can be Software (modem firmware or EFS is damaged, or You have written unsuitable firmware) or HW problem.

You should re-flash the device with different firmwares one by one and check, whether modem is correct (not Unknown). And only then (when phone's modem part will be correct) perform "Repair EFS" and "Write Cert" operations. It is not possible to repair IMEI, if phone's modem part is damaged.

If after writing of all firmwares, which You have, phone's baseband is still null or unknown (SW version is Unknown) - most likely, this is HW problem (problem with eMMC flash chip).

Can i repair emmc or not

If after writing of all firmwares, which You have problem remains the same - yes, You can try to repair EMMC with tool which supports this model.

Thanks .
