Hacking Downgrading for Boot2 installing?

[Yepi69]

Is there a way to downgrade my Wii's System Menu in order to install BootMii as boot2? I soft modded my Wii with 4.3E using Letterbomb and of course have installed bootmii as a IOS and backed up my Wii, but I am a security maniac like that and what I read around Wiihacks is the new 4.3 version had something patched up so Boot2 modification would be impossible, but since 4.2 and previous didn't had so, I was wondering if there's a way to downgrade to those versions, install bootmii as boot2 and possibly put 4.3 again (since boot2's already modified, I'm sure 4.3 will do nothing to boot2)
Thanks

No, if the hackmii installer won't let you install bootmii as boot2, then you don't have the right hardware to do this. Downgrading your SM doens't change anyhting about that.
Bootmii and System menu are independent of eacht other, and to install bootmii as boot2 you need to have a vulnerable boot1(which has a read only memory, so can't be changed)
