KWIQ-ICS

First off, this Rom is based off Evervolv-Acies-2.2.0a1-supersonic with permission of preludedrew.. Please go hit his donate button, he's done more than a lot to bring true ICS to our OG's.

This rom is something I've been working on for fun and to get a better handle on what works for mods and tweaks on 4.x.x roms. I chose Evervolv's base because of it's minimalistic & stable qualities. This is 4.0.4 with HWA combined with what IMO is the fastest most stable kernel I have ran so far on any ICS roms. Most all mods and tweaks are built into the ram-disk so they are present at first boot every boot. This seems to provide for a more responsive experience with the proper settings. I do not claim the settings I've used to be the best possible for ICS or any other roms at this time, the current version will reflect settings I have tried out with positive results. Those parameters are a WIP and I will continue to update as I'm aware of and find better settings, all input and suggestions is highly welcomed. Feel free to run your favorite scripts tweaks and mods, if you would please share your results and best settings. Please read and follow "How To Flash" below for best results

Thanks and enjoy!

How To Flash

​

1) Download rom to sd and verify md5
2) In recovery manually wipe everything except sd card
3) Flash [URL="http://xdaforums.com/attachment.php?attachmentid=452272&d=1291053174"]THIS[/URL] or another cleaner script.
4) Flash rom, when prompted flash GAPPS
5) Reboot
6) Enjoy my bootani, (had the lockscreen up after the 29th "flash", I know..)
7) Skip the set up and disable auto sync
8) Allow phone to "settle in" for a minimum 5 minutes
9) Sign in/sync etc.
10) when all set up reboot

I recommend changing the governor in Evervolv Toolbox/ performance and see what works best with your phone.
