i don't follow why you are inquiring about WiiFlow, but posted a video about GX... you are much more likely to get responses if you communicate intelligibly, so use some punctuation next time.
if you want WF4.1.3 from a much earlier, deprecated version....
0. install d2x v8 final...Modmii is your friend. ideally, you want IOS[56]249 and IOS[57]250 minimum. ...might as well also make sure you have IOS58 installed at this point too.
1. delete or rename :\wiiflow and :\apps\wiiflow. this will essentially be a fresh install.
2. create :\apps\wiiflow and place the 4.1.3 boot.dol in it.
3. launching this via HBC will create the required folder structure (:\wiiflow\ and :\apps\wiiflow\wiiflow.ini). note: don't expect an outdated forwarder to work properly. delete any old forwarder and replace with an appropriate new one.... IIRC, new ones require IOS58.
4. once this is done, you can populate your covers and/or cheats back into it if desired. old themes will cause issues, so just get rid of those.
if you have issues, post a syscheck.
