Hello.
You should wipe security and write correct QCN file.
We support for now just secruity operations in EDL mode, QCN operations will be enabled in near time.

Enable it's digonestic port and write good qcn and repair imei. For enable it's digonestic there r some engg code u can search it

Dear sir help me
 

But i dont have qcn file and cant find anywhere so please help me

Try with reflash modem file
 

Boot into Fastboot mode and flash NON-HLOS.bin from flash file . If not solve then try to flaah with same version as written on back .

Should b fix.
