press *#0011# and check imei certi if fail you have to write cert file, if pass you should try with qcn file. If still problem check hardware solution

Hi. I have S5 Plus (G901F) in hands with same problem - no service. Someone tried to unlock the device. Don't know how, but now it can't connect to any network. The IMEI is OK (original one), the IMEI Certi status in ServiceMode menu is PASS (see screenshot), but I think the QCN data maybe was damaged in unlocking process. I tried to write QCN from device that is confirmed healthy by another user, but situation doesn't change. And I see in logs something strange:

What exactly is the CP in this device - MDM9635 or MDM9235 ?
The exact QCN I'm using to restore data contain: MPSS.BO.1.0.c1-00091-M9635TAARANAZM-1 in its code.

No progress till now. If anyone has an idea lets share with me / us. Even the CERT is PASS and original IMEI is present, and healthy QCN was written - result is no service. Because of the log I already shared, it looks suspicious that in Reset EFS command the Modem board is recognized as MDM9235, and on QCN read/write modem is detected as MDM9635. Is it possible this model manufactured with two different CPs/modems, so QCNs are not cross compatible between two modifications?
