trying to configure mgmt port on cisco 4331 router

[moman62]

port is up:

Interface IP-Address OK? Method Status Protocol
GigabitEthernet0/0/0 unassigned YES NVRAM administratively down down
GigabitEthernet0/0/1 unassigned YES NVRAM administratively down down
GigabitEthernet0/0/2 unassigned YES NVRAM administratively down down
GigabitEthernet0 10.0.10.5 YES NVRAM up up

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.10.5, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)

interface GigabitEthernet0
vrf forwarding Mgmt-intf
ip address 10.0.10.5 255.255.255.0
negotiation auto

I was finally able to login to the webui after:
My IOS is (isr4300-universalk9.17.09.04a.SPA.bin)

connecting to my laptop
configuring laptop ethernet adapter to ip address that is matched to my vrf subnet
configure mgmt port on 4331 router. once configured with ip address/submask it will use default name Mgmt-intf
creating a static route for vrf traffic
creating a username and SHA256 password aka PBKDF2

Hello, i will wrote on this thread because i have same router.

So basically i have this router, configured mgmt interface Gigabit0 with IP/submask then save the config / then reload.
When the router reboot, there is no config file saved , no mgmt port configured.

Tryed 3 times, what i am doing wrong?

enable

conf t

interface gigabitethernet 0

ip address 192.168.1.2 255.255.255.0

no shutdown 

exit

write memory

copy running-config startup-config

reload

after reload there is no configuration.

LE: I have tryed with no reload command, and worked.
I have successfuly accesed the config interface in browser 192.168.1.1 

to upgrade firmware, isr4300-universalk9_npe.17.09.05f.SPA.bin i need license? Where i can download from free?
