I have a GT-i9070 S Advace with similar problem.

It comes with bootloop.
Reflashed with ODIN, cace/data reformat, now working but no sound on back speaker (mic working), no WIFI signal (BT not checked) and no IMEI, shows null / null.

How can i restore the calibrations?
(I assume all of the calibrations are lost, and IMEI is a part of that.)
