Okay, I'm currently on 4.2U and have bootmii as boot2 and as IOS, HBC is 1.0.7(soon will be 1.0.8). I don't remember what I had to do to get Monster Hunter Tri, NTSC-U to work on my system, but in terms of installing cIOS's, i did all of that. Im on cIOS 17 i think. I want to be able to use the Shop channel. I can't cuz I need to update. Now, I don't know if there is a work-around so I don't have to update to use the shop channel, but would it be easier to work around the update, or update and fix it. If it's easier to update to 4.3, can somebody please explain to me how, and for installing cIOSX 20, what numbers should I use for the whole thing(meaning what IOS for the base and what one for the other options). If it matters, I normally play using Config USB Loader. Even if you can just provide links, that'd be great. But please don't link me to the first post when what I need is on page 20 or something like that.
