When in doubt, use the noob thread. So, I don't really know where exactly I stand with all this stuff. My Wii has been through a lot of shit, and it's still working just fine with hacks.
4.1U, bootmii as boot2 (have Nand backup), installed with TP hack on 3.2.
But I've got random outdated version numbers of just about everything. I think I'm on preloader .29 and HBC 1.03. Being a fool, like I was back in the day, I used cioscorp so I could run burned discs through the disc channel, which I have learned later is really bad for the Wii and thus making it unable to update preloader and HBC. Now that I've invested into another external hard drive, I'm using my old smaller one to be dedicated for USB loading. I believe I no longer need the disc channel hacks, if I understand this correctly.
I have read that updating to 4.3 of course is very bad, but I'm under the impression that I can update to 4.2 and still Bannerbomb, rehack and whatever. But my questions are, what's the best way to remove all the cioscorp bullshit? If I update to 4.2 will I lose the ever so important boot2/preloader? (I think that last one's a yes, actually, based on some research).
All in all, what I'm aiming for is, 4.1U menu, preloader/boot2, no Cioscorp, still keeping Trucha bug, and all that important stuff.
Thanks.
