sony xperia m c1904 (single sim)imei null

[shikhasharma]

I rooted my sony xperia m c1904 and i upgraded it to android kitkat (4.4.4 )
and then by mistake i flashed a wrong boot.img on my phone using flashtool....
my phone got bricked . I restored the back up ( of kitkat 4.4.4).
It's working now . But it's not detecting the sim card ..I checked IMEI no. Then it's showing null.
Service menu , engineer mode are also not working .
Please help.
