Downgrade MIUI from JB to ICS

[Mie]

Hi. I'd like to downgrade my I9100 from JB back to last ICS version, so my question is if it's possible and how. Is full wipe sufficient for downgrade? I couldn't find any similar thread, if there is any just post here a link please. Thanks.

Thanks. I have one following question. If I want to flash default miui kernel is necessary to flash it before or i can just make a wipe and then flash rom?

Make wipe ,flash rom and you have MIUI with default kernel .
