First: open up multiman or have your ftp ready, navigate to the file manager/mmOS
Second: open PS3 root/dev_hdd0/home
Third: there will be a bunch of folders depending on how many accounts are on your system and it will start with 6-7 zeros, now say you have 5 users on the ps3 it will go in order the first folder will be the first account on your ps3
Fourth: open whichever folder has the banned psn then go to friendim/avatar and there are all of your friends dont mind the .png its just the picture but the name should appear for all friends added on the account
Or an even easier option is to have a PS4 and send the banned account a friend request (you don't need to accept it) then browse the friends list with the PS4.
So basically make a new account send a friend request to the banned account with the new one and browse the friends list and add them.
Just make sure you don't have the privacy settings on to stop it but this is what I do
This works for anyone without the need for a CFW.
