Thanks Ankur for help. bypassed activation by pressing Vol Up, Vol Down, Back, Home and menu on Configuration Screen.
Now phone is in NV mode and all phone status parameters are showing Unknown.
Phone No,MIN,ESN, MEID Hex, MEID,IMEI, PRL,ICCID, IMSI.
DIAG mode says Excess MSL failure. phone will power off. any suggestion for that?
