This means, that phone's modem part is damaged in your device. This can be Software (modem firmware is damaged or You have written unsuitable firmware) or HW problem.

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

Also try to write firmwares with other Android versions, not only 4.3.

If after of writing 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). Try to change eMMC.
