Default [Q] SM-N9005 no network imei different

dear experts, my friend bought this phone from UAE, and after OTA update the phone has lost network and imei has changed, device is not rooted and knox is still 0x0, so nothing was externally flashed. the current ver is 4.4.2, baseband is N9005XXUENC2, build num is KOT49H.N9005XXUENC2.

Please Help.. THANKS.

P.S.... problem solved after flashing Modem LTE ZHUENB5 from ValenteL's thread
