Trying to Config My ONT from My OLT Using ont-load Function

Hi, guys. After reading the following post:

https://forum.huawei.com/enterprise/en/how-to-upgrade-an-ont-on-the-olt/thread/523185-100181

Tried to reproduce this procedure in my lab. BTW:

FTP server and OLT are both pings reachable.

Here is my procedure:

MA5680T#diagnose 
MA5680T(diagnose)%%ont-load 
{ info<K>|select<K>|start<K>|stop<K> }:info 
{ <cr>|configuration<K>|ftp<K>|program<K>|sftp<K>|tftp<K> }:configuration 
{ filename<S><Length 1-80> }:HG8546M.xml
{ <cr>|ftp<K>|sftp<K>|tftp<K> }:ftp
{ <cr>|server-ip-address<I><X.X.X.X>|username<S><Length 1-16> }:172.30.10.102
{ <cr>|username<S><Length 1-16> }:olt_user
{ <cr>|password<S><Length 1-16> }:olt_321
  Command:
          ont-load info configuration HG8546M.xml ftp 172.30.10.102 olt_user olt_321
MA5680T(diagnose)%%ont-load select 
{ <cr>|frameid/slotid<S><Length 3-15> }:0/12 
{ <cr>|portid<U><0,7> }:7
{ <cr>|ontid<U><0,127> }:7
  Command:
          ont-load select 0/12 7 7
MA5680T(diagnose)%%ont-load start
{ <cr>|activemode<K> }:
  Command:
          ont-load start 
MA5680T(diagnose)%%display ont-load 
{ info<K>|result<K>|select<K> }:select 
{ <cr>|frameid/slotid<S><Length 3-15> }:
  Command:
          display ont-load select 
 --------------------------------------------------------------
   F/S/P          ONT ID         Load state      Load progress 
 --------------------------------------------------------------
   0/12/7              7               Fail                 0%
 --------------------------------------------------------------
MA5680T(diagnose)%%

After doing "ont-load start", I can see:

Mon May 18 16:04:54 2020 1 ::ffff:172.30.10.105 150331 /home/olt_user/HG8546M.xml b _ o r olt_user ftp 0 * c

At my FTP server ... so the XML file is downloaded ... What can I do next to finish ONT loading the XML file?
