Most likely, there was KNOX enabled in your device or phone has secured boot. You should write the same firmware version, that was in the phone before (when it was working).

once you downgraded the phone you can not return to the lower version even it was working before but now the only way to solve is by flashing the latest version with odin ,i fixed 1 M919 this way

Hello.

Install the latest Software version (Software), disable KNOX, root the phone and perform the Repair IMEI operation. Then post here full Software log.
