Homebrew 9.2 to 2.1 downgrade failing.

[DHall243]

Since I can't get into the IRC to ask, I guess this is my last resort.
Ive now tried 4 times with Plaisysupdater and 1 Time with Safesysupdater to downgrade from 9.2 to 2.1, what am I missing. This has failed each time at 0004003000008f02 or CTR-N-HMME. Is it not possible to do this unless you update (or use to be able to update) the Emunand and then downgrade?

In my testing, I had better luck downgrading from 10.7 to 2.1 than I had with downgrading from 9.2 to 2.1. I haven't yet tested downgrading from 11.0 to 2.1, but it should work so long as you're booting your cfw with a 10.2 or 10.4 firmware.bin

Let me try that, quick

That sir was successful, you are my HERO lol Thank you. Upgraded the emunand to 11.0, rebooted, put the 10.2 firmware.bin in luma folder, booted the emunand, launched plaisys and it succeeded
