This is a link to the page for Pattielipp's Miunia ROM.
He advises that you install this rom from a clean froyo install. To do so, follow the instructions on this thread.
OH CRAP I SCREWED MY PHONE UP!!! recovery guide.
The purpose is different, but it will put you at stock froyo for this rom.
This rom is extremely light, and heavily tweaked. It uses IMNUTS hacked stock kernel with several mods for performance. Unlike Nuckin's and Clean, this ROM is an Odin flash.
Also, while advised to install this from stock froyo, it is not required, if you don't feel comfortable doing so. Installing over your current rom, and wiping dalvik will suffice.
The only bug I have noticed, personally, is that my GPS based apps force close. But, that seems to be a rare occurance. Over all, users give this rom high reviews.
One other note. Due to the fact that it is advised to do a clean install, you need to make sure your data (apps, contacts, and anything else you want to keep) is backed up, before you start the install process.
Don't forget to hit his thanks button if you use this rom. Also, please post any kudos or bugs over here, as well as over there. That way other users know what you have experienced. Thank you.
