Thanks Ithian! Have checked. The wiiflow version does not have any R## to it thus should be the original v1.1
There was no \apps\wiiflow folder in the HDD. I think it is the full channel that was installed as I can wiiflow without any boot.dol files.
How would it be to go about updating to R25 if the full channel is installed? I do not have a HBC. Have tried installing it but it failed (installer does not work as no vulnerabilities- tried using the guides in wiihacks.com but to no avail). Tried using wad manager as well but apparently it does not work also (both in installing the R25 wads that Bamboo 77 has so nicely shared and in replacing some ios files so as to install HBC) have some error ret -1 message. Think it might be some incompatibility problems of the wad manager with my wii.
Sorry understand that it might not be relevant to post HBC stuff in this thrend. But would just like to share the things that I have attempted in order to upgrade my wiiflow to at least R25.
Thanks so much for your assistance!
