Now you can safely update to 4.3 using WaninKoko updater. You can keep the HBC now with no worry of being deleted!

Edit: Now that I have tried this app, I would say that its not entirely safe. Since I didn't test it completly, I would just sit back and wait untill a new version of Hackmii installer comes out, and then I would test it. For now, this app is a fail. (Maybe.)

Right now there's absolutely no benefit of updating. I really don't get why you would. google translate gives me a shitty translation, does this stop all the patches ninty put in (anti trucha/hackmii stuff?)

Actually I just tried it myself and I got screwed. When I was going to update, I forgot to put "Patch" and It took me to a regular 4.3 menu. Its risky, and I dont want to downgrade again even though I know how to do it using Dop-Mii. So, I think this app is a No Go. If you have Wiiexplorer or Loadmii, and know how to downgrade carefully to 4.2 be my guest, but I think its just to troublesome to try this again. So If you want to give a shot, and it works for you then tell me. But still, its not worth it. I had to reset all my IOS's and ISO's and its very time consuming.

Oh, I have no intention of upgrading, at least not until an new version of the hackmii installer comes out, and even then I may not.

Yeah, I may just do the same thing.

umm if you got screwed put somthing in the title

By the way, I am just letting you know that I didn't get completly screwed since I had the WiiExplorer channel to access my apps. Oh and, the JODE wad for hbc = FAIL. The wad didnt even boot up after the 4.3 installation. If a new exploit or Hackmii for 4.3 comes out, I will test it and tell you if its safe, patches, block updates, etc. For now leave this app alone

There was an update to this app, I dunno if it fixed your issue though

Where is the link to the update, I may try it again.
