Try to downgrade 5.1.1 if possible why put marshmallow on this phone.

They didnt upgrade the rollback protection bit it is still a 3. Just downgrade the modem to OJ1 and use z3x 23.9

@ markhaines1985 are you tested this solution ?
when flash with different modem phone gone unknown modem and imei null
whats full firmware android 6.01 work with modem G925f Oj1 without imei null

[markhaines1985]

Look at the 3 firmwares below. The middle digit in all of them that I have underlined is what is called the rollback protection bit (RP). As long as that bit is the same or higher than the one of the current firmware on phone you can flash that rom. PBF has same RP as OJ1 that means you can flash OJ1 on a phone with PBF without any issues. That means you can downgrade just the modem without causing an unknown baseband. However, if your phone is on PBF and you flash the OFN rom to it it will cause the baseband to be unknown since the RP is 2 which is lower than the RP of 3 on PBF.

Muchas gracias Markhaines1985, me sirvio tu aporte.
Luego de la actualizacion a 6.0.1, un cliente me trajo un G925F que decia "solo llamadas de emergencia". Luego de 2 dias tratando de reparar redes, escribir cert, etc logre solucionarlo flasheando el modem que dejaste.
Me tiraba error z3x, tanto como octopus antes de flashear tu modem.
El procedimiento lo hice con z3x Samsung Tool Pro V24.7 y salio sin problemas:

1 - Flasehar MODEM_G925F_OJ1, con Odin v3.10.6 en la pestaña PHONE
2 - Rootear con CF-Auto-Root-zerolte-zeroltexx-smg925f
3 - En z3x pestaña "Repair" dar a Reset EFS (recuerden hacer un backup antes)
4 - Escribir nuevamente el IxxI, dar en "Repair"
5 - Dar en "Patch Certificate" (Luego de esto ya deberia dar señal, pero si ponen *#06# veran que S/N figura vacio)
6 - Para recuperar el S/N vuelven a escribir la EFS. Pestaña "Backup" dan en "Write EFS" y buscan el backup que habian hecho anteriormente.

Esa fue mi experiencia y todo se realiza con Samsung Tool PRO v24.7. En octopus no alcance a relizar el procedimiento pero calculo que se debe solucionar tambien. Gracias
