Hello.

Try to write different Cert files. IMEI of Cert file, which You've used might be in "black" list of Network provider.
If problem will persist, or if IMEI is fine, please read out QCN from another, correctly working SM-G900F and write it into your phone.

If IMEI is "clean" and You've used QCN of correctly working phone, but problem remains the same - phone might have HW problem. Please check phone's HW.
