I currently have the firmware 7.1.1 on my modem.

I will need to go to another hub which uses 7.0.5

I understand that I am supposed to downgrade.

Now i know 7.1.1 has two files, the cumulative and the remote package files.

the 7.0.5 has only the remote package file.

so is it the same procedure to downgrade but with only one file?

Select "Download Package"
Select the OPEN button,
Find the remote-7_0_5.pkg file and select it,
Select options: "Dont' check versions" and "Download image only" and "Dont Reset"
then hit start
then once done, hit close
then upload option file and reset

is this procedure correct?

pls advise

Sounds like you have a solid plan.   It should work.

thanks

worked just fine.
