I have the QCN file of redmi note 7, but I am not able to solve my network problem, if you can help me I will be grateful. the link from the QCN file QCN Archive

Dude your QCN file is corrupted! That's why you can't restore it! Find a QCN file, replace your IMEI,MEID and MAC then restore it on the phone!
